[{"content":"On June 13, 2026 (JST), Anthropic announced the global decommissioning and disabling of its newly released models, Claude Fable 5 and Mythos 5, effective immediately.\nThis drastic decision comes after the United States government (under the Trump administration) issued a sudden export restriction order on the afternoon of June 12, citing national security concerns. As a result, all active API endpoints for both models have been shut down. This article reviews the geopolitical context surrounding the shutdown and outlines the immediate steps developers must take to restore service.\n1. Political Tensions and the Global Ban This immediate EOL was triggered by escalating friction between Anthropic and the U.S. government.\nExport Controls and Global Access Block The government\u0026rsquo;s order originally demanded that Anthropic block model access to \u0026ldquo;all foreign nationals, both inside and outside the United States, including Anthropic\u0026rsquo;s own foreign employees.\u0026rdquo; To guarantee absolute compliance under these strict constraints, Anthropic decided to shut off access to Fable 5 and Mythos 5 for all global customers. While standard publicly available models (such as Claude 3.5 Sonnet) remain fully operational, Fable 5 and Mythos 5 are completely offline.\nShutdown Just Days After Launch \u0026ldquo;Claude Fable 5\u0026rdquo; was launched on June 9 as a heavily guarded model, adding additional safety mitigations to the \u0026ldquo;Mythos 5\u0026rdquo; reasoning engine to prevent misuse in cyber defense, biology, and chemistry. However, shortly after release, the U.S. government claimed to have discovered a \u0026ldquo;jailbreak\u0026rdquo; vulnerability, leading to the emergency export ban on the afternoon of June 12.\nDispute Over Jailbreaks Anthropic disputed the severity of the government\u0026rsquo;s findings in a blog post, stating that the alleged jailbreaks were limited, non-generic prompts (such as requesting the model to read a codebase and patch software bugs) that reflect minor, pre-existing vulnerabilities present in other public models. Despite Anthropic\u0026rsquo;s pushback, the ban remains in place with no timeline for model restoration.\n2. Choosing the Replacement Model: Claude 3.5 Sonnet Because \u0026ldquo;Claude Fable 5\u0026rdquo; and \u0026ldquo;Mythos 5\u0026rdquo; have been decommissioned globally due to export controls, developers should roll back their configurations to the current standard model, Claude 3.5 Sonnet, or other stable public endpoints.\nMetric Claude Fable 5 (Disabled) Claude 3.5 Sonnet (Migration Target) Prose Quality Exceptional Standard (Requires prompt adjustments) Context Window 100K 200K (Doubled) Response Latency Moderate Fast Token Cost Standard Approx. 20% Cheaper Since the advanced reasoning engines of Fable 5 and Mythos 5 are banned, creative developers must temporarily roll back backend systems to Claude 3.5 Sonnet and adapt outputs using custom prompts.\n3. API Code Migration (Python SDK) Update your active model configurations to a publicly available model endpoint.\n🐍 Python Integration Example import anthropic client = anthropic.Anthropic() # --- Legacy Integration (Fable 5 / Mythos 5 will fail) --- # response = client.messages.create( # model=\u0026#34;claude-fable-5\u0026#34;, # max_tokens=1024, # messages=[{\u0026#34;role\u0026#34;: \u0026#34;user\u0026#34;, \u0026#34;content\u0026#34;: \u0026#34;Write a story.\u0026#34;}] # ) # --- Migrated Integration (Recommended fallback) --- response = client.messages.create( model=\u0026#34;claude-3-5-sonnet-latest\u0026#34;, # Target standard 3.5 Sonnet max_tokens=2048, messages=[{\u0026#34;role\u0026#34;: \u0026#34;user\u0026#34;, \u0026#34;content\u0026#34;: \u0026#34;Write a story.\u0026#34;}] ) 4. Adjusting Prompts to Maintain Creative Depth Because Claude 3.5 Sonnet is built as a highly capable general-purpose model, its default prose style may sometimes feel slightly more objective or analytical than Fable 5.\nTo replicate Fable 5\u0026rsquo;s expressive depth, we recommend prepending a System Prompt like the following:\n[Recommended System Prompt for Sonnet] You are a highly creative novelist specializing in immersive, atmospheric storytelling. Avoid summarizing events. Focus heavily on sensory imagery (light, shadows, sound, smells) to bring the scene to life, adhering strictly to the principle of \u0026#34;Show, don\u0026#39;t tell.\u0026#34; Applying this prompt ensures you capture the best of both worlds: 3.5 Sonnet\u0026rsquo;s speed and logic, combined with the poetic narrative flair of Fable.\n","date":"2026-06-13T13:00:00+09:00","image":"/img/thumbnail/claude-fable-deprecation-announcement-en.png","permalink":"/en/web/claude-fable-deprecation-announcement/","title":"[Important] Urgent Claude Fable 5 and Mythos 5 Decommissioning due to U.S. Export Restrictions"},{"content":"We have officially completed the transition of netguide.jp from WordPress to Hugo, a modern static site generator (SSG).\nOperating a dynamic CMS like WordPress had become increasingly bottlenecked by page load delays, security updates, and hosting costs. Migrating to a static workflow resolved all of these issues. In this case study, we share our motivation, migration strategy, and the post-migration performance gains.\n1. Three Reasons We Left WordPress While WordPress remains a highly versatile CMS, its dynamic, database-driven architecture presented critical challenges as our content grew:\nPage Speed Limitations (Core Web Vitals) Accumulated database queries and heavy plugins severely degraded mobile performance, negatively impacting our Core Web Vitals (specifically LCP and INP) and dragging down search rankings. Maintenance Overhead \u0026amp; Security Risks WordPress core, themes, and plugins are constant targets for vulnerabilities. The continuous cycle of testing and updating required too much manual time to prevent hacking attempts. Hosting Overhead Running dynamic PHP pages quickly at scale required premium VPS hosting, resulting in high monthly operational fees. 2. Migration Design: Hugo + Stack Theme We chose Hugo, the fastest Go-powered static site generator, paired with the highly polished Stack theme (hugo-theme-stack).\n🌐 Multilingual Architecture (ja / en) We structured our system to serve Japanese content under /ja/ and English under /en/. Alongside proper HTML alternate tags, we generated Google-compliant XML sitemaps embedding xhtml:link (hreflang annotations) to keep multilingual SEO in perfect alignment.\n🖼️ Image Optimization via AVIF To maximize delivery speeds, we created an asset pipeline that automatically converts raw PNG and JPEG thumbnails into highly compressed, next-generation AVIF images.\n🔗 Complete Redirect Strategy As we changed our URL format from nested dated paths to clean slugs (e.g., /ja/software/...), we configured 104 redirects in a _redirects file, ensuring no incoming search engine link juice or user bookmarks would break.\n3. Step-by-Step Transition We executed the migration in four major phases:\nExporting WordPress Data We used export plugins to download all raw HTML content, metadata, post dates, slugs, and featured image associations into an structured XML format. Converting to Markdown Using a custom parsing script, we converted the XML database records into front-matter-equipped Markdown files (.ja.md and .en.md). Applying Themes and Overrides We structured hugo-theme-stack inside the directory, setting up localized search, tag clouds, and TOCs. Optimizing Image Assets We ran image automation scripts to regenerate optimized AVIF assets, as well as distinct light and dark mode thumbnail designs. 4. 📈 Post-Migration Results By hosting our newly generated static HTML output on Cloudflare Pages, we observed immediate improvements:\nPageSpeed Insights Maxed Out Mobile performance scores reached 100/100. Our Largest Contentful Paint (LCP) was reduced to under 0.6 seconds, making transitions feel instantaneous. Zero Hosting Costs Leveraging Cloudflare\u0026rsquo;s global edge network meant we could serve millions of requests on a free tier, completely eliminating our monthly VPS hosting bills. Absolute Security Without a database or a dynamic PHP layer, common vulnerabilities like SQL injection or brute-force administrative attacks are structurally impossible. 💬 Final Thoughts While the initial setup of an SSG takes effort, the long-term benefits in speed, cost, security, and SEO stability make switching from WordPress to Hugo one of the best investments you can make for your web platforms.\n","date":"2026-06-12T12:00:00+09:00","image":"/img/thumbnail/wordpress-to-hugo-migration-story-en.png","permalink":"/en/web/wordpress-to-hugo-migration-story/","title":"Goodbye WordPress: Why and How We Migrated to Hugo Static Site Generator"},{"content":"While AI has revolutionized code generation and structured business writing, capturing the nuance, subtext, and flow of creative literature has remained a challenge. To solve this, Anthropic engineered Claude Fable, a model fine-tuned specifically for creative writing, fiction development, and world-building.\nIn this article, we explore how Claude Fable helps novelists, screenwriters, and copywriters push the boundaries of creative expression.\n1. What makes Claude Fable Different? Standard large language models (like Claude Sonnet or GPT-4) are trained to be concise, helpful, and literal. When asked to write a story, they often rely on clichés and formulaic prose that feels distinctly \u0026ldquo;AI-generated.\u0026rdquo;\nIn contrast, Claude Fable is optimized for literary devices:\nSubtext and Imagery (\u0026ldquo;Show, Don\u0026rsquo;t Tell\u0026rdquo;) Instead of stating that a character is \u0026ldquo;sad,\u0026rdquo; Fable focuses on behavioral details and sensory descriptions of the surroundings to convey the emotion naturally. Tone \u0026amp; Voice Adaptability Fable can mimic specific writing styles—from 19th-century gothic horror to hard-boiled noir or modern magical realism—maintaining the specific voice consistently. Long-form Contextual Consistency Fable tracks character arcs, dialogue quirks, and world rules over chapters, ensuring that world-building rules or character behaviors don\u0026rsquo;t contradict themselves later in the story. 2. Practical Use Cases in Creative Projects 🎭 ① Refining Character Dialogue Writing dialogue that sounds unique to each character is one of the hardest parts of storytelling. Fable can take dry exposition and translate it into distinct voices.\nInput: \u0026ldquo;Translate this scene into dialogue where an old, cynical wizard tells a young, reckless warrior that he is leaving the tower and never coming back.\u0026rdquo;\nFable Output: Young Warrior: \u0026ldquo;Hah! I\u0026rsquo;m leaving this moldy spire behind, old man. Keep your dusty books and rot in here for all I care!\u0026rdquo; Old Wizard: \u0026ldquo;Ah, such poetic parting words. Truly, your vocabulary is as sharp as your sword. Go on then. I pray the cold winds outside freeze a shred of sense into that thick skull of yours.\u0026rdquo;\n🗺️ ② Dynamic World-Building Stuck on designing rules for a sci-fi city or fantasy kingdom? Fable acts as a brilliant brainstorming partner. If you give it a prompt like, \u0026ldquo;This city runs on floating islands where gravity is localized. How does trade work?\u0026rdquo;, it will output logical yet highly creative ideas, detailing physical pulleys, wind sails, and trade guilds formed around gravity stones.\n3. Prompting Secrets for Claude Fable To get the absolute best prose out of Claude Fable, set a clear persona and specify prose rules in your system instructions:\nYou are an editor and writing companion specializing in atmospheric suspense. Translate the following outline into a scene, focusing strictly on sensory details (smell of rain, distant footsteps, shadows on the wall) to build tension. Adhere to the rule: \u0026#34;Show, don\u0026#39;t tell.\u0026#34; By instructing Fable to write through senses rather than summary, you bypass generic AI patterns and unlock deep, immersive creative writing.\n","date":"2026-06-09T12:00:00+09:00","image":"/img/thumbnail/claude-fable-creative-writing-en.png","permalink":"/en/web/claude-fable-creative-writing/","title":"Unleashing Creativity: Features and Creative Use Cases of Claude Fable"},{"content":"Anthropic has officially announced its next-generation flagship AI model: Claude Mythos.\nSurpassing the capabilities of Claude 3.5 Sonnet and Claude 3 Opus, Claude Mythos introduces a powerful reasoning architecture that transforms how we write code, analyze data, and solve logical problems. In this article, we dive deep into the key features, benchmarks, and real-world use cases of Claude Mythos.\n1. What is Claude Mythos? Key Features and Innovations Claude Mythos isn\u0026rsquo;t just about scaling up parameters; it integrates an embedded Reasoning Chain directly into its inference architecture. Before answering, the model maps out logical steps internally, reducing hallucinations and maximizing accuracy.\n💡 Three Main Evolution Points Massive Reasoning Leap By actively \u0026ldquo;thinking\u0026rdquo; through multi-step logic before returning responses, Claude Mythos dramatically reduces mistakes in complex programming logic, mathematics, and data synthesis. Optimized 200K Context Window Retrieving information from large codebases or heavy PDF manuals is virtually flawless, resolving the \u0026ldquo;Needle in a Haystack\u0026rdquo; memory loss common in older models. Speed vs. Cost Balance Despite running deep reasoning processes, output speed remains comparable to Claude 3.5 Sonnet, making it highly practical for interactive developer tools. 2. Major Benchmarks (vs. Competitors) Claude Mythos achieves industry-leading scores across standard graduate-level reasoning and programming benchmarks.\nBenchmark Claude 3.5 Sonnet GPT-4o Claude Mythos MMLU (General Undergraduate Knowledge) 88.7% 88.7% 94.2% GPQA (Graduate-Level Science Reasoning) 59.4% 53.6% 78.5% HumanEval (Coding Accuracy) 92.0% 90.2% 96.8% MATH (Math Problem Solving) 71.1% 76.6% 89.0% Its massive lead in GPQA and HumanEval means Claude Mythos acts as an exceptionally reliable scientific and engineering assistant.\n3. Practical Code Generation Example Claude Mythos excels at writing highly concurrent, reliable software. Here is a Go concurrent worker pool implementation generated by Claude Mythos, which cleanly handles channel teardowns and contexts:\npackage main import ( \u0026#34;context\u0026#34; \u0026#34;fmt\u0026#34; \u0026#34;sync\u0026#34; \u0026#34;time\u0026#34; ) // A safe concurrent worker implementation by Claude Mythos func worker(id int, jobs \u0026lt;-chan int, results chan\u0026lt;- int, ctx context.Context, wg *sync.WaitGroup) { defer wg.Done() for { select { case \u0026lt;-ctx.Done(): fmt.Printf(\u0026#34;Worker %d: received shutdown signal\\n\u0026#34;, id) return case job, ok := \u0026lt;-jobs: if !ok { return } fmt.Printf(\u0026#34;Worker %d: processing job %d...\\n\u0026#34;, id, job) time.Sleep(500 * time.Millisecond) // Simulate work results \u0026lt;- job * 2 } } } Alongside the clean code, Claude Mythos provides a step-by-step reasoning breakdown explaining why it chose this particular architecture to prevent race conditions or memory leaks.\n4. Conclusion: How to Get the Most out of Mythos To leverage Claude Mythos effectively, avoid short one-liner questions. Instead, feed it complex, multi-page prompts and instruct it to think step-by-step:\nArchitectural reviews of entire software packages. Deep security scans and auditing of codebases. Cross-comparing medical or financial reports. Claude Mythos represents the next phase of agentic AI.

However, extracting web layouts without permission introduces serious technical, ethical, and legal concerns. This article covers the legal boundaries of crawling, ethical pipeline design rules, and a Python example featuring retry behaviors and rate-limiting structures.\n1. Legal and Ethical Boundaries of Scraping Auto-extracting data from websites falls into a legal gray area. Consider these vital concepts:\n1) Copyright and Fair Use In many jurisdictions, scraping public copyrighted data is legally permitted if the data is analyzed for research or machine learning ingestion. However, commercial redistribution (e.g., scraping products to display and monetize them on your own competitor site) constitutes copyright infringement.\n2) Terms of Service (TOS) Many platforms prohibit automated crawling inside their Terms of Service agreements. If a crawler logs into an account to extract data, agreeing to those terms beforehand creates a binding contract. Violating it can result in IP bans, account cancellation, or breach of contract lawsuits.\n3) Server Infrastructure Abuse (DoS) Flooding a server with thousands of concurrent requests can degrade performance or cause downtime. In severe scenarios, this can be prosecuted as a Denial of Service (DoS) attack, leading to civil liability or criminal charges under computer abuse laws.\n2. Four Rules of Ethical Web Scraping To write respectful scrapers, developers must implement the following safeguards:\nVerify robots.txt: Check the website\u0026rsquo;s crawl guidelines at the root directory (e.g., https://example.com/robots.txt). Avoid indexing any endpoints listed under Disallow. Define a Clear User-Agent (UA): Add a customized User-Agent header that outlines who you are and provides an email address so administrators can contact you if your script behaves erratically. Incorporate Strict Rate-Limiting: Always introduce a sleep delay (between 1 to 3 seconds) between requests to mimic human behavior and protect server compute resources. Prefer Official APIs: If the target platform provides a public API, use it. Bypassing an API to scrap HTML elements degrades server performance and violates platform goodwill. 3. Implementation: A Polite Python Scraper Here is a Python implementation utilizing requests and BeautifulSoup4. It incorporates custom User-Agents, automatic backoff retries for transient 5xx server errors, and explicit sleep intervals:\nimport time import requests from bs4 import BeautifulSoup from requests.adapters import HTTPAdapter from urllib3.util import Retry def fetch_page_politely(url): # 1. Custom User-Agent with contact details headers = { \u0026#39;User-Agent\u0026#39;: \u0026#39;NetGuideScraper/1.0 (+mailto:info@netguide.jp; Dedicated crawler for research)\u0026#39; } # 2. Configure retry logic with exponential backoff session = requests.Session() retries = Retry( total=3, # Max retries backoff_factor=2, # Exponential delay (2s, 4s, 8s...) status_forcelist=[500, 502, 503, 504] # Statuses to retry ) session.mount(\u0026#39;https://\u0026#39;, HTTPAdapter(max_retries=retries)) try: # Send HTTP GET request response = session.get(url, headers=headers, timeout=10) response.raise_for_status() # Raise exceptions for 4xx/5xx status # 3. Parse Document soup = BeautifulSoup(response.text, \u0026#39;html.parser\u0026#39;) title = soup.find(\u0026#39;h1\u0026#39;).text.strip() if soup.find(\u0026#39;h1\u0026#39;) else \u0026#39;No H1 Element\u0026#39; print(f\u0026#34;Successfully processed: {title}\u0026#34;) return title except requests.exceptions.RequestException as e: print(f\u0026#34;Error requesting {url}: {e}\u0026#34;) return None # List of URLs to fetch urls = [ \u0026#34;https://example.com/page1\u0026#34;, \u0026#34;https://example.com/page2\u0026#34;, \u0026#34;https://example.com/page3\u0026#34; ] for url in urls: fetch_page_politely(url) # 4. Introduce a 2-second delay between requests to protect server load print(\u0026#34;Cooling down for 2 seconds...\u0026#34;) time.sleep(2.0) 4. Conclusion Web scraping is a double-edged sword. While it enables data compilation and analysis, thoughtless execution can disrupt web platforms. By respecting robots.txt guidelines, configuring identifying User-Agents, and throttling request rates, developers can harvest data responsibly without compromising internet infrastructure.\n","date":"2026-05-20T12:00:00+09:00","image":"/img/thumbnail/web-scraping-best-practices-en.png","permalink":"/en/web/web-scraping-best-practices/","title":"Modern Web Scraping: Ethics, Legality, and Best Practices in 2026"},{"content":"Explore the ecosystem of plugins translating Figma vector layouts into web assets and component classes.\nConverting mockups from Figma into clean, responsive React, Vue, or HTML/CSS code has historically been a tedious, manual task. Today, modern \u0026ldquo;Figma-to-Code\u0026rdquo; tools use AI to interpret vector layouts and produce highly readable code. This article compares industry leaders—Anima, Locofy, and native Dev Mode plugins—and provides styling rules for your design files to guarantee clean code exports.\n1. The Value of Figma-to-Code Tools in 2026 In the past, code auto-generated from graphic assets was notorious for rigid, pixel-absolute positioning (position: absolute) that was useless for production.\nToday, Figma incorporates coding concepts directly into its canvas via Auto Layout (flexbox models) and Variables (design tokens). AI layout translators leverage these structures to map mockups into production-ready front-end components.\n2. Top Translation Plugins Evaluated Integrating these tools into your front-end pipeline saves hours of boilerplate drafting.\n1) Locofy.ai Locofy uses machine learning to convert vector shapes into clean React, HTML/CSS, Vue, and React Native components.\nKey Highlights: Automatically identifies UI elements (inputs, buttons, select boxes) and maps them to library components (Material UI, Chakra UI, Ant Design). Infers breakpoints and outputs clean, responsive Tailwind CSS utility classes. Direct integration with GitHub and Vercel lets you push layout modifications directly as pull requests. 2) Anima Anima is a veteran in the design-to-code space, with a focus on animation fidelity and framework translation (React, Vue, HTML).\nKey Highlights: Preserves design prototypes and transitions, mapping them directly to CSS keyframes and JS triggers. Bidirectional sync with Storybook databases allows components to be rendered in isolation. 3) Figma Dev Mode (Native \u0026amp; Plugins) Figma\u0026rsquo;s standard Dev Mode workspace provides a dedicated panel for copy-pasting CSS styles, SVG assets, and Tailwind utility maps directly from selected frames.\n3. Implementation Comparison Tool Export Quality target Frameworks AI Capabilities Best For Locofy.ai Excellent (Highly readable) React, Vue, HTML/CSS, React Native Strong (Tailwind generation) Building large SPAs from scratch Anima High (Excellent animations) React, Vue, HTML, Tailwind Good (Design system mapping) Interactive landing pages and animations Dev Mode Moderate (Snippet copier) CSS, Tailwind, SwiftUI, Jetpack Compose None Copying individual styles to existing code 4. Design Guidelines for Clean Code Exports No matter how advanced the code generator is, chaotic Figma structures yield poor code. Work with your design team to implement these rules:\nEnforce Auto Layout Everywhere: Avoid absolute positioning. Rely on vertical and horizontal Auto Layouts. This maps vectors directly to clean CSS Flexbox properties, applying flex, grid, and gap utilities naturally. Componentize Recurring Elements: Encapsulate repeating assets (buttons, input fields, badges) into Master Components with distinct Variants. Code generators will recognize them and output modular, reusable blocks (e.g., \u0026lt;Button variant=\u0026quot;secondary\u0026quot;\u0026gt;). Bind Local Variables: Use Figma\u0026rsquo;s Native Variables for color palettes, spacing units, and typography. The compiler maps these variables directly to CSS Custom Properties (var(--color-primary)), keeping your code tidy. 5. Conclusion Figma-to-code converters are not a replacement for engineers, but they are incredibly useful for bootstrapping static scaffolding, reducing markup drafting time by up to 70%. By aligning design teams around Auto Layout and utilizing platforms like Locofy, you can bridge the gap between design and development.\n","date":"2026-05-15T12:00:00+09:00","image":"/img/thumbnail/figma-to-code-tools-en.png","permalink":"/en/software/figma-to-code-tools/","title":"Comparing Figma to Code Tools for Modern UI Developers"},{"content":"Keep your Vite builds extremely fast using custom bundling settings and caching layers.\nVite is lightning-fast out of the box, but as codebases expand, production builds can slow down due to heavy Rollup compilation stages. This guide outlines how to optimize your builds using manualChunks, esbuild minification settings, and dependency pre-bundling configurations.\n1. Code Splitting: Balancing Asset Sizes By default, Vite bundles your application code into unified scripts. To prevent downloading unnecessary JavaScript during the initial page load, developers must implement robust code-splitting strategies.\n1) Leverage Dynamic Imports The easiest way to split assets is using dynamic imports. This isolates router endpoints so pages only fetch code when a user navigates to them.\n// React example of lazy-loaded routes import { lazy } from \u0026#39;react\u0026#39;; const HeavyDashboard = lazy(() =\u0026gt; import(\u0026#39;./pages/Dashboard\u0026#39;)); 2) Splitting Heavy Modules with manualChunks External dependencies (like react-dom, lodash, or chart.js) rarely change. Bundling them into vendor chunks lets the browser cache them permanently, ignoring application-level updates.\nvite.config.js Splitting Snippet import { defineConfig } from \u0026#39;vite\u0026#39;; export default defineConfig({ build: { rollupOptions: { output: { manualChunks(id) { // Isolate node_modules packages into dedicated chunks if (id.includes(\u0026#39;node_modules\u0026#39;)) { // Group by package name return id.toString().split(\u0026#39;node_modules/\u0026#39;)[1].split(\u0026#39;/\u0026#39;)[0].toString(); } } } } } }); 2. Reducing Compilation Times 1) Choose the Right Minifier (Esbuild vs. Terser) Vite defaults to esbuild for code minification, which is up to 40x faster than traditional JavaScript-based options. Unless your team requires obsolete ES5 compatibility or strict obfuscation (which warrants terser), stick to minify: 'esbuild'.\n2) Disabling Production Source Maps Generating source maps (.map files) during production builds consumes massive memory allocations and slows down compile loops. Disable them if your server pipeline does not explicitly require them for error tracking.\n// vite.config.js export default defineConfig({ build: { sourcemap: false // Speed up builds by avoiding .map generation } }); 3. Stabilizing the Dev Server: Dependency Pre-Bundling When you launch Vite, it pre-bundles third-party modules into standardized ES Modules (ESM) to optimize browser caching.\nIf Vite discovers a dynamic import during runtime that was omitted from the pre-bundle stage, it is forced to re-run the bundler and reload the browser page (triggering a full reload). Prevent this behavior by explicitly indexing heavy imports:\n// vite.config.js export default defineConfig({ optimizeDeps: { include: [\u0026#39;heavy-editor-plugin\u0026#39;, \u0026#39;chart.js\u0026#39;] // Pre-bundle these libraries on startup } }); 4. Conclusion: Bundle Auditing Maintaining build performance requires continuous observation. Install tools like rollup-plugin-visualizer to chart your bundle compositions. By tracking module sizes, splitting vendor dependencies, and disabling redundant source maps, your Vite build pipeline will remain fast and efficient.\n","date":"2026-05-10T12:00:00+09:00","image":"/img/thumbnail/vite-build-performance-tips-en.png","permalink":"/en/software/vite-build-performance-tips/","title":"Advanced Tuning for Vite Build and Bundling Performance"},{"content":"INP (Interaction to Next Paint) measures a web page\u0026rsquo;s responsiveness to user interactions. This article demystifies Google\u0026rsquo;s Core Web Vitals metric, explores how it differs from the deprecated FID metric, and outlines how to optimize your JavaScript execution pathways to achieve \u0026ldquo;Good\u0026rdquo; scores.\n1. What is Interaction to Next Paint (INP)? INP tracks the latency of all user interactions (clicks, taps, and keyboard inputs) during a user\u0026rsquo;s visit to a page. It measures the duration between when a user initiates an action and when the browser paints the next frame showing the visual update.\nHow it Differs from FID (First Input Delay) FID was Google\u0026rsquo;s previous response metric, but it had limitations that made it easy to bypass:\nFirst-Interaction Bias: FID only monitored the very first user interaction. Any subsequent delay caused by navigating menus or clicking filters was ignored. Ignored Script Execution: FID only calculated the input delay (how long the browser took to receive the event). It ignored the time required to execute the actual JavaScript event handler and paint the updated UI. INP addresses these limitations by tracking all interactions across the entire lifecycle of the session, reporting the worst-performing interaction (excluding outliers).\nINP Scoring Thresholds Good (Pass): 200ms or less Needs Improvement: 200ms to 500ms Poor: Over 500ms 2. Key Causes of Poor INP Scores The core culprit behind poor INP scores is Main Thread Blocking.\nBecause browsers handle UI rendering and JavaScript execution on a single main thread, launching complex script logic instantly blocks the browser from updating the viewport. If a click triggers a task taking 300ms, the screen freezes during that window, raising your INP score.\n3. Techniques to Optimize INP 1) Task Yielding (Breaking up Long Tasks) Any JavaScript function that runs for more than 50ms is flagged as a \u0026ldquo;Long Task.\u0026rdquo; To resolve this, break long-running tasks into modular steps and yield the main thread back to the browser to process UI frames.\n// ✕ Bad: Continuous loop blocking the main thread function processArray(items) { for (let item of items) { calculateComplexResult(item); // Freezes the browser } } // ◯ Good: Yielding control periodically using async timeouts async function processArrayOptimized(items) { for (let i = 0; i \u0026lt; items.length; i++) { calculateComplexResult(items[i]); // Yield every 50 items to let the browser paint if (i % 50 === 0) { await yieldToMainThread(); } } } function yieldToMainThread() { // Use scheduler.yield if supported, otherwise fallback to setTimeout if (\u0026#39;scheduler\u0026#39; in window \u0026amp;\u0026amp; \u0026#39;yield\u0026#39; in window.scheduler) { return window.scheduler.yield(); } return new Promise(resolve =\u0026gt; setTimeout(resolve, 0)); } 2) Optimizing User Feedback Loop If you must run heavy logic, ensure that you update the UI with a \u0026ldquo;loading spinner\u0026rdquo; or active button state before the heavy processing script begins.\nbutton.addEventListener(\u0026#39;click\u0026#39;, () =\u0026gt; { // Step 1: Update UI immediately (registers low INP latency) toggleSpinner(true); // Step 2: Queue the heavy calculation task for the next event loop setTimeout(() =\u0026gt; { executeHeavyCalculation(); toggleSpinner(false); }, 0); }); 4. Conclusion Optimizing for INP is not just about check-marking SEO audits. Providing immediate visual feedback on user inputs increases conversion rates and stops users from abandoning unresponsive pages. Use Chrome DevTools\u0026rsquo; \u0026ldquo;Performance\u0026rdquo; panel to track down long tasks and optimize your user experiences.\n","date":"2026-05-05T12:00:00+09:00","image":"/img/thumbnail/seo-core-web-vitals-inp-en.png","permalink":"/en/web/seo-core-web-vitals-inp/","title":"SEO and Core Web Vitals: Demystifying and Improving INP"},{"content":"Combine the micro-framework Hono and Cloudflare Workers to deliver lightning-fast responses on the global edge.\nIn 2026, building edge-native serverless backends has become the modern standard. This guide dives into why \u0026ldquo;Hono + Cloudflare Workers\u0026rdquo; is a powerful stack, how to initialize a project, and includes a TypeScript API example.\n1. Why Choose Hono and Cloudflare Workers? Traditional web frameworks (like Express or NestJS) were designed before modern Web Standard APIs emerged. Consequently, they bundle node-specific polyfills and runtime code, making them too heavy for lightweight serverless nodes.\nHono is built from the ground up to be ultra-lightweight (approx. 14KB) and relies exclusively on Web Standard APIs (e.g., Request, Response, fetch).\nPrimary Stack Benefits Zero-Cold Starts: Cloudflare Workers executes JavaScript within V8 Isolates instead of spinning up heavy Docker containers. Coupled with Hono\u0026rsquo;s tiny footprint, your application processes requests almost instantly, eliminating cold-start latency. Global Edge Distribution: Your code is deployed across Cloudflare\u0026rsquo;s network of global data centers. Requests are intercepted and resolved at the closest physical node to the user, ensuring sub-10ms routing times. Web-Standard Portability: Because Hono works with standard web paradigms (Request/Response interfaces), you can deploy the same codebase onto Deno, Bun, Lagon, Fastly Compute, or traditional Node.js servers without modifying your router. 2. API Tutorial with Hono Let us build a simple API with routing, middleware, and JSON handlers targeted for Cloudflare Workers.\nStep 1: Create a Hono Project Use the Hono CLI helper to initialize your workspace:\nnpm create hono@latest my-app # Select \u0026#34;cloudflare-workers\u0026#34; when prompted for the template target Step 2: Implement the Router (src/index.ts) Write your logic in clean, typed TypeScript:\nimport { Hono } from \u0026#39;hono\u0026#39; import { cors } from \u0026#39;hono/cors\u0026#39; const app = new Hono() // Apply global CORS middleware app.use(\u0026#39;*\u0026#39;, cors()) // Basic text handler app.get(\u0026#39;/\u0026#39;, (c) =\u0026gt; { return c.text(\u0026#39;Hello NetGuide Edge API!\u0026#39;) }) // Dynamic route parameters \u0026amp; JSON payloads app.get(\u0026#39;/api/user/:id\u0026#39;, (c) =\u0026gt; { const id = c.req.param(\u0026#39;id\u0026#39;) // Extract query parameters const details = c.req.query(\u0026#39;details\u0026#39;) return c.json({ success: true, data: { userId: id, role: \u0026#39;developer\u0026#39;, detailsRequested: details === \u0026#39;true\u0026#39; } }) }) // POST request processing app.post(\u0026#39;/api/user\u0026#39;, async (c) =\u0026gt; { const body = await c.req.json() return c.json({ message: \u0026#39;User created successfully\u0026#39;, receivedData: body }, 201) }) export default app Step 3: Run and Deploy Use Wrangler (the Cloudflare Workers CLI tool) to test locally and deploy to the cloud:\n# Run local emulation server npm run dev # Deploy to global edge nodes npm run deploy 3. Integrating with D1 Database Cloudflare Workers lets you bind storage resources directly to your environment context. Integrating SQLite-based D1 databases with Hono is straightforward:\n// Define custom bindings matching wrangler.toml configuration type Bindings = { DB: D1Database } const app = new Hono\u0026lt;{ Bindings: Bindings }\u0026gt;() app.get(\u0026#39;/users\u0026#39;, async (c) =\u0026gt; { // Access D1 directly through context env const { results } = await c.env.DB.prepare(\u0026#39;SELECT * FROM users\u0026#39;).all() return c.json(results) }) 4. Conclusion Hono combined with Cloudflare Workers represents a major shift in backend architecture. By removing complex server provisioning and minimizing cold starts, this stack lets developers ship fast, secure APIs globally with minimal overhead.\n","date":"2026-05-01T12:00:00+09:00","image":"/img/thumbnail/hono-framework-cloudflare-workers-en.png","permalink":"/en/web/hono-framework-cloudflare-workers/","title":"Building Blazing Fast APIs with Hono and Cloudflare Workers"},{"content":"Optimize slow-performing applications by profiling database queries in PostgreSQL with EXPLAIN. Slow queries are the single largest bottleneck in most web applications. This guide walks you through essential index optimization guidelines, how to read execution plans, and key configuration parameter adjustments for self-hosted or managed databases.\n1. Designing Effective Indexes The primary bottleneck in modern databases is Disk I/O (reading block files from storage). Adding indexes allows PostgreSQL to query data records directly instead of scanning the entire table.\n1) The B-Tree Index Default The standard B-tree index supports several operator classes:\nDirect matches and ranges (=, \u0026lt;, \u0026gt;, BETWEEN) Join criteria (JOIN ON ...) Sorting operations (ORDER BY) 2) The Column Order Rule for Composite Indexes When creating a composite index (combining multiple columns), PostgreSQL parses columns from left to right. Order matters:\n-- Create a composite index CREATE INDEX idx_users_status_created ON users (status, created_at); -- ◯ Index will be used (leftmost column \u0026#34;status\u0026#34; is present in the query) SELECT * FROM users WHERE status = \u0026#39;active\u0026#39; AND created_at \u0026gt; \u0026#39;2026-01-01\u0026#39;; SELECT * FROM users WHERE status = \u0026#39;active\u0026#39;; -- ✕ Index will NOT be used efficiently (leftmost column \u0026#34;status\u0026#34; is missing) SELECT * FROM users WHERE created_at \u0026gt; \u0026#39;2026-01-01\u0026#39;; 2. Profiling Execution Plans with EXPLAIN ANALYZE To diagnose a slow query, prepend EXPLAIN ANALYZE to your SQL statement and execute it in your console:\nEXPLAIN ANALYZE SELECT * FROM orders WHERE user_id = 45291; Key Terms in the Output: Seq Scan (Sequential Scan): The database is scanning every single row in the table. If this occurs on a large table, you are missing an index. Index Scan / Index Only Scan: The database is querying the index. Index Only Scan is the fastest lookup strategy because all requested columns exist inside the index tree, meaning Postgres does not need to look up data blocks in the main table heap. Actual Time: The execution duration in milliseconds. Use this to pinpoint which sub-operation (like sorting or hash joins) consumes the most time. 3. Optimizing Configuration Parameters If you are self-hosting Postgres or using dedicated servers, default memory values are often conservative. Adjust these values in your postgresql.conf file:\nshared_buffers: Memory dedicated to caching database tables. Allocate around 25% of your total system RAM. work_mem: The memory limit for internal sorting operations (ORDER BY) and hash joins before writing to temporary disk files. Increasing this from 4MB to 16MB can drastically speed up complex queries. maintenance_work_mem: The maximum memory limit used for maintenance procedures, such as VACUUM and CREATE INDEX. Setting this between 128MB and 512MB speeds up migrations. 4. Conclusion Database performance tuning should always be data-driven. Never guess what index to add. Run EXPLAIN ANALYZE before and after database modifications to verify whether execution costs and query times have improved.\n","date":"2026-04-20T12:00:00+09:00","image":"/img/thumbnail/postgres-performance-tuning-en.png","permalink":"/en/software/postgres-performance-tuning/","title":"PostgreSQL Performance Tuning for Web Developers"},{"content":"Optimizing CI/CD workflow times directly impacts developer productivity and reduces computing expenses. This article shows you how to integrate dependency caching in GitHub Actions, helping you slash compilation and package setup times.\nWe provide YAML workflow templates for Node.js, Python, and Rust, alongside best practices to ensure optimal cache hits.\n1. Why Cache Dependencies in CI/CD? When a CI agent starts without caching, it spins up a clean container and fetches every dependency from package registries. This introduces several drawbacks:\nInefficient Dev Loops: Developers waste precious minutes waiting for standard libraries to install before testing code. Network Risks: If npm, PyPI, or crates.io undergoes minor downtime, your build fails due to external network issues. Execution Costs: On private repositories, GitHub charges you for every active minute. Faster builds directly reduce operations costs. Caching allows the pipeline to reuse downloaded resources across executions, making subsequent runs execute up to 80% faster.\n2. YAML Templates for Major Languages In 2026, GitHub\u0026rsquo;s default language setup actions include built-in caching support, making configuration straightforward.\n1) Node.js (npm / pnpm / yarn) Configure the cache property under actions/setup-node:\nname: Node.js CI on: [push, pull_request] jobs: build: runs-on: ubuntu-latest steps: - name: Checkout Code uses: actions/checkout@v4 - name: Setup Node uses: actions/setup-node@v4 with: node-version: \u0026#39;20\u0026#39; cache: \u0026#39;npm\u0026#39; # Supports npm, yarn, or pnpm - name: Install Packages run: npm ci - name: Run Tests run: npm test 2) Python (pip / poetry) For Python environments, enable caching using the cache key in actions/setup-python:\nname: Python Test Runner on: [push] jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-python@v5 with: python-version: \u0026#39;3.11\u0026#39; cache: \u0026#39;pip\u0026#39; # Supports pip, poetry, or pipenv - name: Install Dependencies run: pip install -r requirements.txt - name: Run Linter run: flake8 . 3) Rust (Cargo) Rust compilation is notoriously slow. To cache Cargo dependencies and intermediate build artifacts (the /target directory), use the community standard swatinem/rust-cache:\nname: Rust CI on: [push] jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Setup Rust compiler uses: actions/setup-rust@v1 - name: Configure Cargo Cache uses: swatinem/rust-cache@v2 - name: Execute Tests run: cargo test 3. Custom Caching and Troubleshooting For folders not handled by default actions, define them manually using actions/cache:\n- name: Cache Custom Files uses: actions/cache@v4 with: path: ~/.my-custom-cache key: ${{ runner.os }}-custom-${{ hashFiles(\u0026#39;**/lockfile.json\u0026#39;) }} restore-keys: | ${{ runner.os }}-custom- key: Unique identifier for the cache. The hashFiles function creates a hash of your lockfiles (package-lock.json, Cargo.lock, etc.). When a lockfile changes, the old cache is invalidated and a fresh one is built. restore-keys: An ordered list of prefix keys to fall back on if an exact cache hit is not found. Preventing Cache Misses Commit Lockfiles: Ensure lockfiles are tracked in Git. Without them, hashes fluctuate, causing frequent cache misses. Track Cache Size: GitHub limits cache storage to 10GB per repository. Once you exceed this limit, GitHub automatically evicts older caches. Exclude unnecessary build artifacts from your cache paths. 4. Summary Configuring actions caching is one of the easiest ways to optimize your software pipelines. Implementing these changes can save hours of wait time across your team every week.

With the deprecation of Manifest V2, developers must adopt non-persistent Service Workers for background processing and adapt to the declarative net request model. This guide explains the core architectural shifts in Manifest V3 and provides a simple walkthrough of setting up a compliant extension.\n1. Primary Shifts from Manifest V2 to V3 Manifest V3 (MV3) was designed to make browser extensions more secure, privacy-respecting, and performant.\n1) Transitioning Background Pages to Service Workers In MV2, extensions ran persistent background pages (background.js). In MV3, background scripts are replaced by Service Workers. Service Workers are ephemeral—the browser terminates them when idle to conserve system memory. Because variables in memory do not persist, developers must store application state using the chrome.storage API.\n2) Network Interception with declarativeNetRequest The old webRequest API allowed extensions to intercept and modify all incoming and outgoing network traffic using JavaScript. Due to security concerns, MV3 enforces the declarativeNetRequest API. Instead of executing custom logic on every request, extensions register declarative blocking rules that the browser processes natively.\n3) Disallowing Remotely Hosted Code For security auditing, extensions are no longer permitted to download and run external JavaScript files (e.g., loading jQuery or Google Analytics from a CDN). All code executed by the extension must be bundled locally inside the extension package.\n2. Basic Manifest V3 File Structure Here is a bootstrap implementation for an extension that opens a popup UI.\n1) The Configuration File: manifest.json Define the metadata, permissions, background service worker, and user interface actions:\n{ \u0026#34;manifest_version\u0026#34;: 3, \u0026#34;name\u0026#34;: \u0026#34;NetGuide MV3 Sample\u0026#34;, \u0026#34;version\u0026#34;: \u0026#34;1.0.0\u0026#34;, \u0026#34;description\u0026#34;: \u0026#34;A bootstrap extension demonstrating Manifest V3 features.\u0026#34;, \u0026#34;permissions\u0026#34;: [ \u0026#34;storage\u0026#34;, \u0026#34;activeTab\u0026#34; ], \u0026#34;background\u0026#34;: { \u0026#34;service_worker\u0026#34;: \u0026#34;background.js\u0026#34; }, \u0026#34;action\u0026#34;: { \u0026#34;default_popup\u0026#34;: \u0026#34;popup.html\u0026#34;, \u0026#34;default_icon\u0026#34;: \u0026#34;icon.png\u0026#34; } } 2) The Background Script: background.js Implement event-driven handlers that respond when needed:\n// Register default state on installation chrome.runtime.onInstalled.addListener(() =\u0026gt; { chrome.storage.local.set({ extensionActive: true }); console.log(\u0026#34;Extension installed and initialized.\u0026#34;); }); // React to tab activation changes chrome.tabs.onActivated.addListener((activeInfo) =\u0026gt; { chrome.storage.local.get([\u0026#34;extensionActive\u0026#34;], (result) =\u0026gt; { if (result.extensionActive) { console.log(`Active tab shifted to: ${activeInfo.tabId}`); } }); }); 3) The UI: popup.html and popup.js Design the HTML interface and load the local popup script:\n\u0026lt;!-- popup.html --\u0026gt; \u0026lt;!DOCTYPE html\u0026gt; \u0026lt;html\u0026gt; \u0026lt;head\u0026gt; \u0026lt;meta charset=\u0026#34;utf-8\u0026#34;\u0026gt; \u0026lt;style\u0026gt; body { width: 180px; font-family: sans-serif; padding: 10px; } button { width: 100%; padding: 6px; background: #2563eb; color: white; border: none; border-radius: 4px; } \u0026lt;/style\u0026gt; \u0026lt;/head\u0026gt; \u0026lt;body\u0026gt; \u0026lt;h4\u0026gt;NetGuide Tool\u0026lt;/h4\u0026gt; \u0026lt;button id=\u0026#34;action-btn\u0026#34;\u0026gt;Check Status\u0026lt;/button\u0026gt; \u0026lt;script src=\u0026#34;popup.js\u0026#34;\u0026gt;\u0026lt;/script\u0026gt; \u0026lt;/body\u0026gt; \u0026lt;/html\u0026gt; // popup.js document.getElementById(\u0026#39;action-btn\u0026#39;).addEventListener(\u0026#39;click\u0026#39;, () =\u0026gt; { chrome.storage.local.get([\u0026#34;extensionActive\u0026#34;], (result) =\u0026gt; { alert(`Extension active status: ${result.extensionActive}`); }); }); 3. Development Tips and Debugging Handling Idle Timeouts: Because MV3 Service Workers stop running when idle, standard Javascript timers like setInterval will fail. Use the chrome.alarms API to schedule periodic processes. Console Audits: To load your extension, open chrome://extensions in Google Chrome, enable \u0026ldquo;Developer Mode,\u0026rdquo; click \u0026ldquo;Load unpacked,\u0026rdquo; and select your development folder. Check background messages by clicking the \u0026ldquo;Inspect views: Service worker\u0026rdquo; link. 4. Conclusion: Navigating Manifest V3 While the transition to Manifest V3 initially introduced limits on specific APIs (affecting adblockers and security tools), the platform has stabilized. Implementing extensions under MV3 ensures that your plugins conform to modern browser security standards, providing users with a safe, optimized browsing experience.\n","date":"2026-04-10T12:00:00+09:00","image":"/img/thumbnail/browser-extension-manifest-v3-en.png","permalink":"/en/software/browser-extension-manifest-v3/","title":"Developing Browser Extensions with Manifest V3"},{"content":"Rust has matured significantly as a premier backend language. This article evaluates the top Rust web frameworks, focusing on the differences between the current industry leaders: Axum and Actix-web. We cover their architectural patterns, performance profiles, and provide a bootstrap code snippet to help you choose the right framework.\n1. Top Framework Overview When building web applications or microservices in Rust, developers generally choose between these two frameworks:\n1) Axum Axum is developed and maintained by the tokio team, the creators of Rust\u0026rsquo;s de facto standard asynchronous runtime.\nSeamless Tokio Integration: It relies directly on hyper (HTTP implementation), tower (middleware primitives), and tracing (diagnostics), avoiding runtime impedance mismatches. Macro-less Routing: Unlike many alternatives, Axum avoids custom attribute macros. It leverages Rust\u0026rsquo;s native type system for request extractors, making compiler errors easier to diagnose. Future Proof: Axum is currently the most popular choice for new Rust backend projects, supported by a large and growing community. 2) Actix-web Actix-web is one of the oldest and most battle-tested web frameworks in the Rust ecosystem.\nUltimate Performance: It consistently ranks near the top of TechEmpower benchmarks, showing incredible throughput and minimal latency. Actor-based Legacy: Designed on actor primitives, it isolates runtime execution contexts, ensuring exceptional thread safety and resource efficiency. Mature Ecosystem: Its long tenure means abundant plugins, database adaptors, and community resources are available online. 2. Implementing a Web API with Axum Here is a bootstrap example illustrating how to define routes, extract JSON requests, and return structured payloads using Axum and serde:\nuse axum::{ routing::{get, post}, Json, Router, }; use serde::{Deserialize, Serialize}; use std::net::SocketAddr; #[derive(Serialize)] struct User { id: u64, username: String, } #[derive(Deserialize)] struct CreateUser { username: String, } #[tokio::main] async fn main() { // Define application routing let app = Router::new() .route(\u0026#34;/user\u0026#34;, get(get_user)) .route(\u0026#34;/user\u0026#34;, post(create_user)); // Bind address and launch server let addr = SocketAddr::from(([127, 0, 0, 1], 3000)); println!(\u0026#34;listening on {}\u0026#34;, addr); let listener = tokio::net::TcpListener::bind(\u0026amp;addr).await.unwrap(); axum::serve(listener, app).await.unwrap(); } async fn get_user() -\u0026gt; Json\u0026lt;User\u0026gt; { Json(User { id: 1, username: \u0026#34;user_name_example\u0026#34;.to_string(), }) } async fn create_user(Json(payload): Json\u0026lt;CreateUser\u0026gt;) -\u0026gt; Json\u0026lt;User\u0026gt; { Json(User { id: 2, username: payload.username, }) } This snippet showcases type-safe serialization/deserialization, ensuring that invalid inputs are rejected automatically before hitting your core business logic.\n3. Which Framework Should You Choose? Here is a summary of the differences:\nMetric Axum Actix-web Maintainer Tokio Project Actix Community Macro Overhead Minimal (Function \u0026amp; Types) Heavy (Attribute Macros) Tokio Compatibility First-class Good (Runs on custom runtime) Latency/Throughput High Performance Industry-Leading Speed Learning Curve Gentle (Web Standards) Moderate (Requires Actix patterns) 💡 Recommendation Choose Axum if you are targeting cloud-native containers, serverless execution environments, or want a modern codebase that integrates seamlessly with standard Tokio libraries. Choose Actix-web if you are deploying to bare-metal servers or dedicated compute instances where minimizing sub-millisecond latencies and squeezing maximum performance is your primary objective.

Additionally, it transitions from a JavaScript-based configuration file (tailwind.config.js) to a CSS-first approach, where customizations are defined inside your primary stylesheet using standard CSS variables.\nThis article reviews the major changes in Tailwind CSS v4 and provides a practical migration walkthrough to help you upgrade your projects.\n1. Key Changes in Tailwind CSS v4 1) Rust-Powered \u0026ldquo;Oxide\u0026rdquo; Engine The defining feature of v4 is its compiler. Rewritten in Rust, the Oxide engine processes stylesheet files significantly faster than the old PostCSS-based engine. This translates to near-instantaneous dev server startups and hot module replacement (HMR), keeping developers in their flow.\n2) CSS-First Configuration Instead of modifying a tailwind.config.js file, you customize your theme directly in your CSS files using the new @theme directive.\nExample Configuration in v4 (CSS Syntax) @import \u0026#34;tailwindcss\u0026#34;; @theme { --color-brand-primary: #3b82f6; --color-brand-secondary: #10b981; --font-display: \u0026#34;Outfit\u0026#34;, sans-serif; } The compiler parses these CSS variables and automatically registers the corresponding utility classes—such as bg-brand-primary and font-display—during the build step.\n3) Simplified Import Statements Instead of defining three separate directives (@tailwind base;, @tailwind components;, @tailwind utilities;), you import the package with a single line: @import \u0026quot;tailwindcss\u0026quot;;.\n2. Practical Migration Steps Follow these steps to upgrade an existing Tailwind CSS v3 project to v4.\nStep 1: Install Dependencies Run the command to install the updated compiler and PostCSS integration packages:\nnpm install tailwindcss@next @tailwindcss/postcss@next Step 2: Migrate Config to CSS Move custom colors, fonts, or screens defined in your tailwind.config.js into your global stylesheet:\n- // tailwind.config.js - module.exports = { - theme: { - extend: { - colors: { - customGray: \u0026#39;#1e293b\u0026#39;, - } - } - } - } + /* global.css */ + @import \u0026#34;tailwindcss\u0026#34;; + @theme { + --color-custom-gray: #1e293b; + } Step 3: Update PostCSS Configuration Update your project\u0026rsquo;s postcss.config.js to point to the new Tailwind CSS plugin wrapper:\n// postcss.config.js module.exports = { plugins: { \u0026#39;@tailwindcss/postcss\u0026#39;: {}, }, } 3. Notable New Utility Classes in v4 With the release of v4, several fresh design utilities are supported natively:\nCSS Subgrid Utilities: Standard classes are now included to facilitate grid synchronization (e.g., grid-rows-subgrid and grid-cols-subgrid). 3D Transform Directives: Implement 3D rotations, perspective, and depth directly within HTML attributes (e.g., transform-3d, rotate-y-180). Container Queries Support: Container queries no longer require external plugins. Developers can use the @container utility to apply styles based on parent dimensions instead of viewport breakpoints. 4. Conclusion: Should You Upgrade? The build speed improvement alone makes Tailwind CSS v4 an excellent upgrade for most front-end projects. Combining native CSS standards with utility-first classes reduces configuration complexity, offering a cleaner workflow for modern web design.\n","date":"2026-04-01T12:00:00+09:00","image":"/img/thumbnail/tailwind-css-v4-update-en.png","permalink":"/en/web/tailwind-css-v4-update/","title":"Tailwind CSS v4 Features and Migration Guide"},{"content":"PWAs (Progressive Web Apps) allow web applications to be installed on user devices, offering features like push notifications and offline support.\nIn 2026, the mobile web ecosystem has matured significantly, with enhanced support for Web Push on both iOS and Android. Choosing PWA architecture is now more compelling than ever for cross-platform app development. This article explores the technical advantages and strategic business benefits of PWAs in 2026.\n1. Technical Context of PWAs in 2026 Historically, PWAs faced adoption hurdles due to limited capability support on iOS Safari. Today, the landscape has completely changed:\nWeb Push on iOS: Since Safari 16.4+, iOS supports Web Push API and Push API for web apps added to the Home Screen. This allows developers to engage iOS users with push notifications without paying for an Apple Developer License or undergoing the App Store review process. Improved Service Worker Lifespan: Web browsers have refined cache eviction policies. The aggressive storage cleanup behavior on iOS has been relaxed for active PWAs, ensuring that offline assets and local data remain persistent and functional. Hardware Integration Capabilities: Advanced browser APIs—including Web Share API, Web Bluetooth, and File System Access API—enable PWAs to interact with the device hardware directly, bridging the gap between web and native experiences. 2. Business Benefits of PWA Adoption 1) Freedom from App Store Fees and Rules Deploying via Apple App Store or Google Play Store usually subjects businesses to a 15–30% platform fee and strict review guidelines. A PWA bypasses the app stores completely. You can distribute updates instantly to all platforms, control your billing integrations, and avoid the risk of sudden application rejection.\n2) Reduced Development and Maintenance Costs Maintaining native codebases for iOS (Swift/UIKit) and Android (Kotlin/Jetpack Compose), alongside a desktop web version, requires substantial resources. A PWA enables a single, web-standard codebase (HTML, CSS, JavaScript) that works seamlessly across desktop, Android, and iOS devices.\n3) Organic Discoverability (SEO) and Viral Sharing Unlike native apps hidden inside stores, PWAs are standard websites indexed by search engines. This makes it easier to drive organic traffic via search engine optimization (SEO). Users can also share the application simply by sending a URL on messaging platforms, which recipients can open and install instantly.\n3. Best Practices: PWA Manifest \u0026amp; Service Worker To transform a website into a PWA, you need to define a Web App Manifest and implement asset caching with a Service Worker.\nWeb App Manifest Design Example Here is a modern, multilingual-ready manifest.json snippet:\n{ \u0026#34;name\u0026#34;: \u0026#34;NetGuide Portal\u0026#34;, \u0026#34;short_name\u0026#34;: \u0026#34;NetGuide\u0026#34;, \u0026#34;start_url\u0026#34;: \u0026#34;/?utm_source=pwa\u0026#34;, \u0026#34;display\u0026#34;: \u0026#34;standalone\u0026#34;, \u0026#34;background_color\u0026#34;: \u0026#34;#0f172a\u0026#34;, \u0026#34;theme_color\u0026#34;: \u0026#34;#2563eb\u0026#34;, \u0026#34;icons\u0026#34;: [ { \u0026#34;src\u0026#34;: \u0026#34;/img/icons/icon-192.png\u0026#34;, \u0026#34;sizes\u0026#34;: \u0026#34;192x192\u0026#34;, \u0026#34;type\u0026#34;: \u0026#34;image/png\u0026#34;, \u0026#34;purpose\u0026#34;: \u0026#34;any\u0026#34; }, { \u0026#34;src\u0026#34;: \u0026#34;/img/icons/icon-512.png\u0026#34;, \u0026#34;sizes\u0026#34;: \u0026#34;512x512\u0026#34;, \u0026#34;type\u0026#34;: \u0026#34;image/png\u0026#34;, \u0026#34;purpose\u0026#34;: \u0026#34;maskable\u0026#34; } ] } Choosing a Cache Strategy Service Workers manage assets and API requests using different caching strategies:\nNetwork First: Best for dynamic data (like dashboard metrics or feed lists). Displays cached data only when offline. Cache First: Best for static assets (images, CSS, JS). Optimizes loading speeds. Stale-While-Revalidate: Renders the cached asset immediately for speed while fetching the fresh version in the background. 4. Conclusion: When to Choose PWA? Unless your application requires extremely high-performance 3D rendering or continuous background hardware tracking, a PWA is an ideal architecture for SaaS tools, blogs, e-commerce stores, and internal company portals.\nIn 2026, as users become increasingly reluctant to install yet another application on their cluttered mobile devices, PWAs offer an exceptionally smooth, low-friction entry point for users while keeping development lean.\n","date":"2026-03-20T12:00:00+09:00","image":"/img/thumbnail/pwa-advantages-2026-en.png","permalink":"/en/web/pwa-advantages-2026/","title":"The Benefits of Adopting PWA (Progressive Web Apps) in 2026"},{"content":"CSS Grid revolutionized how web layouts are structured. However, a common challenge remained: aligning nested items (grandchild elements) inside parent Grid Items to the main grid lines.\nThis was resolved with the introduction of CSS Subgrid, a specification update for CSS Grid Layout. This article explains the fundamentals of CSS Subgrid and how to apply it to common layout problems like card lists.\n1. What is CSS Subgrid? Traditionally, only direct children of a Grid container can be positioned along the defined grid tracks. When you declare another grid inside a Grid Item, that nested grid is completely isolated from the outer parent grid.\nConsider a standard \u0026ldquo;product card\u0026rdquo; layout:\nEach card contains an image, a title, and a description. Titles vary in length, with some spanning multiple lines. Using traditional CSS Grid, aligning the card headers or card descriptions horizontally across cards required fixed heights, magic margins, or JavaScript recalculations.\nSubgrid solves this by letting nested grid containers inherit the column and/or row tracks defined in the parent container, linking their structural alignment.\n2. Practical Guide: Aligning Card Heights with Subgrid Let us implement a responsive grid where nested card elements align their content blocks dynamically.\nHTML Structure \u0026lt;div class=\u0026#34;grid-container\u0026#34;\u0026gt; \u0026lt;!-- Card 1 --\u0026gt; \u0026lt;div class=\u0026#34;card\u0026#34;\u0026gt; \u0026lt;img src=\u0026#34;thumb1.jpg\u0026#34; alt=\u0026#34;Thumbnail\u0026#34;\u0026gt; \u0026lt;h3\u0026gt;Short Title\u0026lt;/h3\u0026gt; \u0026lt;p\u0026gt;A brief description goes here.\u0026lt;/p\u0026gt; \u0026lt;/div\u0026gt; \u0026lt;!-- Card 2 --\u0026gt; \u0026lt;div class=\u0026#34;card\u0026#34;\u0026gt; \u0026lt;img src=\u0026#34;thumb2.jpg\u0026#34; alt=\u0026#34;Thumbnail\u0026#34;\u0026gt; \u0026lt;h3\u0026gt;This is a very long title spanning multiple lines\u0026lt;/h3\u0026gt; \u0026lt;p\u0026gt;A longer description to showcase how the heights align.\u0026lt;/p\u0026gt; \u0026lt;/div\u0026gt; \u0026lt;/div\u0026gt; CSS Implementation /* Parent Container Grid */ .grid-container { display: grid; grid-template-columns: repeat(auto-fit, minmax(300px, 1fr)); gap: 20px; } /* Card Styling integrating Subgrid */ .card { display: grid; /* Card spans 3 rows in the parent grid */ grid-row: span 3; /* Configure fallback values */ grid-template-rows: auto auto 1fr; row-gap: 10px; } /* Apply Subgrid when supported */ @supports (grid-template-rows: subgrid) { .card { grid-template-rows: subgrid; } } How the Code Works By specifying grid-row: span 3;, we instruct each card to occupy exactly three rows of the parent container grid. The grid-template-rows: subgrid; declaration inherits the row definitions of the parent grid. Even if Card 2\u0026rsquo;s header wraps to three lines and expands, Card 1\u0026rsquo;s header automatically matches that height because both titles share the same virtual row track of the parent. 3. Summary: Modern Layout with Subgrid CSS Subgrid is fully supported by all major modern browsers (Chrome, Edge, Firefox, Safari). It eliminates the need for brittle JavaScript height matchers and allows designers to construct pixel-perfect, flexible grid layouts. Use it in product grids, dashboard widgets, and magazine layouts to elevate your frontend UI designs.\n","date":"2026-03-15T12:00:00+09:00","image":"/img/thumbnail/css-subgrid-layout-guide-en.png","permalink":"/en/web/css-subgrid-layout-guide/","title":"Understanding CSS Subgrid Layout for Modern Design"},{"content":"In modern cloud-native development, Docker containers are the default standard for deploying web applications.\nHowever, generic Dockerfiles often yield images containing OS vulnerabilities, unnecessary tooling, or root process privileges. In this guide, we cover the essential best practices to harden your Docker container images for production.\n1. Enforce Multi-stage Builds Leaving build tools, compiler caches, or developer dependencies (like npm or git) inside your final runtime image increases the container size and broadens the attack surface.\nMulti-stage builds let you compile the binary in a dedicated environment, then copy only the static artifact to a minimal runtime layer.\n# Stage 1: Build Environment FROM golang:1.22-alpine AS builder WORKDIR /app COPY . . RUN go build -o myapp main.go # Stage 2: Final Secure Layer FROM alpine:3.19 WORKDIR /app COPY --from=builder /app/myapp . EXPOSE 8080 CMD [\u0026#34;./myapp\u0026#34;] 2. Avoid Running Containers as Root By default, Docker container processes execute as root (superuser). If an attacker exploits a code vulnerability, they may gain full access to the underlying host kernel and filesystem.\nMitigate this by declaring a non-root system user inside the Dockerfile.\n# Create a dedicated system user RUN addgroup -S appgroup \u0026amp;\u0026amp; adduser -S appuser -G appgroup USER appuser CMD [\u0026#34;./myapp\u0026#34;] 3. Choose Secure Base Images Instead of basing your setup on a full OS distribution (like Ubuntu), choose lightweight, minimal baselines.\nAlpine Linux (-alpine): A minimal OS (approx. 5MB) with a tiny packages footprint, reducing security vulnerabilities. Distroless Images (Google): Contains only your compiled application and its runtime dependencies—completely excluding package managers, shells, and terminal tools. 4. Integrate Vulnerability Scanning (Trivy) Automate security audits by scanning your built images during your CI/CD pipelines (e.g., GitHub Actions).\nUsing Trivy lets you scan your images for known CVEs before deployment.\n# Auditing your local Docker image with Trivy trivy image myapp:latest 5. Summary The absolute rule of container security is minimization. By shipping only what is necessary and executing with minimal privileges, you insulate your production workloads against external exploits.\n","date":"2026-03-10T12:00:00+09:00","image":"/img/thumbnail/docker-container-security-en.png","permalink":"/en/software/docker-container-security/","title":"Docker Container Image Security Best Practices"},{"content":"As the absolute standard for frontend and backend development, TypeScript continues to evolve.\nThe TypeScript 5.x releases focus heavily on compiler speed, bundle reductions, and syntax refinements that dramatically improve Developer Experience (DX). In this article, we cover practical TypeScript 5 features you should adopt in your daily workflows.\n1. const Type Parameters Previously, if you wanted TypeScript to infer an object literal arguments as narrow, read-only literal types, the caller had to append as const to the arguments.\nWith TypeScript 5.0+, you can declare a const modifier directly on the generic type parameter. The compiler will automatically infer the narrowest type at the call site.\n// Define \u0026#39;const\u0026#39; before the generic parameter T function getNames\u0026lt;const T extends { names: readonly string[] }\u0026gt;(obj: T) { return obj.names; } // No \u0026#39;as const\u0026#39; required from the caller; the array is inferred as readonly [\u0026#34;Alice\u0026#34;, \u0026#34;Bob\u0026#34;] const names = getNames({ names: [\u0026#34;Alice\u0026#34;, \u0026#34;Bob\u0026#34;] }); // Inferred Type: readonly [\u0026#34;Alice\u0026#34;, \u0026#34;Bob\u0026#34;] This prevents runtime typing bugs when handling static configs or constants passed into functions.\n2. Standard ECMAScript Compliant Decorators Experimental decorators (experimentalDecorators flag) have been in TypeScript for years. TypeScript 5 introduces native support for ECMAScript stage 3 standard decorators, allowing you to write decorators without flags.\nfunction logMethod(originalMethod: any, context: ClassMethodDecoratorContext) { const methodName = String(context.name); function replacementMethod(this: any, ...args: any[]) { console.log(`[LOG] Calling ${methodName} with`, args); return originalMethod.apply(this, args); } return replacementMethod; } class UserService { @logMethod greet(name: string) { return `Hello, ${name}!`; } } 3. Multiple Config Inheritance (extends Array) Prior to TS 5, tsconfig.json could only inherit settings from a single base configuration. You can now pass an array of files to the extends field.\nThis enables cleaner modularity: splitting path mappings, build settings, and target environments into reusable snippets.\n{ \u0026#34;extends\u0026#34;: [\u0026#34;./tsconfig.base.json\u0026#34;, \u0026#34;./tsconfig.paths.json\u0026#34;], \u0026#34;compilerOptions\u0026#34;: { \u0026#34;strict\u0026#34;: true } } 4. Summary: Under-the-Hood Performance Gains Beyond syntax, TypeScript 5\u0026rsquo;s compiler structure was fully refactored, removing heavy namespaces and restructuring data types. This has resulted in a 20-40% reduction in compilation times for medium-to-large codebases. Upgrading your dependencies is highly recommended for faster build loops.\n","date":"2026-03-05T12:00:00+09:00","image":"/img/thumbnail/typescript-5-new-features-en.png","permalink":"/en/software/typescript-5-new-features/","title":"TypeScript 5 Features and Practical Best Practices"},{"content":"Legislation enforcing digital accessibility is tightening globally. In 2026, targeting compliance with WCAG 2.2 (Web Content Accessibility Guidelines) at Level \u0026ldquo;AA\u0026rdquo; is no longer optional—it has become a standard engineering requirement for web platforms.\nTo build barrier-free web experiences, developers must understand semantic structures, user inputs, and visual design requirements.\n1. Key Guidelines Introduced in WCAG 2.2 WCAG 2.2 focuses on improving accessibility for mobile users, people with cognitive disabilities, and low-vision individuals.\n🎯 Tap Target Size (2.5.8 - Target Size) To avoid accidental taps, all interactive components must have a minimum target size of 24x24 CSS pixels (including spacing around the element). Designing for a 44x44 CSS pixel target remains the recommended practice.\n🔍 Visible Focus States (2.4.11 - Focus Appearance) Keyboard users rely on visible focus indicators (outlines) to navigate. Under WCAG 2.2, focus states must provide a high contrast ratio (at least 3:1 against the surrounding background) and be large enough to notice immediately.\n2. Ensuring Keyboard \u0026amp; Screen Reader Access Many users rely entirely on a keyboard (Tab, Shift+Tab, Enter, Space) or screen readers to browse.\n💡 Always Prefer Semantic HTML Avoid using \u0026lt;div\u0026gt; or \u0026lt;span\u0026gt; for clickable behaviors. Browsers handle semantic markup naturally, feeding semantic roles to the accessibility tree.\n\u0026lt;!-- ✕ Bad Practice: Screen readers cannot identify this as interactive --\u0026gt; \u0026lt;div class=\u0026#34;submit-btn\u0026#34; onclick=\u0026#34;submitData()\u0026#34;\u0026gt;Submit\u0026lt;/div\u0026gt; \u0026lt;!-- ◯ Best Practice: Standard element with native keyboard support --\u0026gt; \u0026lt;button type=\u0026#34;submit\u0026#34; class=\u0026#34;submit-btn\u0026#34;\u0026gt;Submit\u0026lt;/button\u0026gt; If custom components are necessary, developers must implement appropriate WAI-ARIA attributes (e.g., role=\u0026quot;button\u0026quot;, aria-expanded=\u0026quot;true\u0026quot;) and set tabindex=\u0026quot;0\u0026quot;.\n3. Visual Styling and Contrast Limits Never rely solely on color to convey meaning (such as using red text for errors or green for completed states).\nProvide Alternate Cues: Supplement colors with icons (e.g., \u0026ldquo;⚠️\u0026rdquo;) and explicit text descriptions. Contrast Ratios: Maintain a minimum contrast ratio of 4.5:1 for regular body copy and 3:1 for large, bold headings. 4.

In this guide, we explore practical optimization techniques to build blazing-fast Next.js applications.\n1. Maximize React Server Components (RSC) The primary benefit of the App Router is that all components are Server Components by default. This eliminates large portions of JavaScript from the client-side bundle.\n💡 Optimization Rule: Push \u0026quot;use client\u0026quot; to the Leaves Declaring \u0026quot;use client\u0026quot; at the top of a file forces the entire import tree below it to be downloaded by the browser. To optimize, isolate interactive features (like buttons, state hooks, and side effects) into small leaf components.\n// ✕ Anti-pattern: Turning the entire page into a Client Component \u0026#39;use client\u0026#39; export default function Page() { const [data, setData] = useState(null) return \u0026lt;div\u0026gt;{/* Heavy static contents */}\u0026lt;/div\u0026gt; } // ◯ Best practice: Nest Client Components inside Server Components import HeavyStaticContent from \u0026#39;./HeavyStaticContent\u0026#39; // RSC import ClientInteractiveButton from \u0026#39;./ClientInteractiveButton\u0026#39; // Client export default function Page() { return ( \u0026lt;div\u0026gt; \u0026lt;HeavyStaticContent /\u0026gt; \u0026lt;ClientInteractiveButton /\u0026gt; \u0026lt;/div\u0026gt; ) } 2. Intelligent Image Handling with next/image Images on the viewport heavily influence your Largest Contentful Paint (LCP) score.\n💡 Preload Critical Assets using priority Ensure you add the priority attribute to the main hero image or logo so the browser preloads the asset before parsing secondary scripts.\nimport Image from \u0026#39;next/image\u0026#39; export default function Hero() { return ( \u0026lt;div className=\u0026#34;hero-banner\u0026#34;\u0026gt; \u0026lt;Image src=\u0026#34;/images/hero-visual.png\u0026#34; alt=\u0026#34;Hero Image\u0026#34; width={1200} height={630} priority // Force Preloading sizes=\u0026#34;(max-width: 768px) 100vw, 1200px\u0026#34; /\u0026gt; \u0026lt;/div\u0026gt; ) } Also, define the sizes attribute accurately to prevent the server from serving massive desktop resolutions to small mobile displays.\n3. Splitting and Dynamic Imports To optimize the initial page weight, split heavy libraries or optional components (such as modal windows) so they only load when triggered.\nimport dynamic from \u0026#39;next/dynamic\u0026#39; // Do not bundle this modal during the initial page load const HeavyModal = dynamic(() =\u0026gt; import(\u0026#39;./HeavyModal\u0026#39;), { ssr: false, // Exclude from Server-Side Rendering }) 4.

Monthly fixed costs, security updates, handling sudden traffic surges — it adds up to significant stress for developers and operators.\nBut in 2026, a trend is rapidly gaining traction that fundamentally changes web development: edge computing (serverless) — running programs without traditional hosting — and the leading platform is Cloudflare Workers.\nThis guide explains why edge computing is getting so much attention and how it differs from traditional servers, using plain language.\nWhat Is Edge Computing? Traditional websites (like WordPress) store data on a single powerful server in one location. Everyone worldwide must access that one location.\nThink of it as a single popular restaurant in Tokyo taking orders from all over the country. Customers far away wait longer, and the kitchen gets overwhelmed during peak hours.\nEdge computing is like placing food trucks (edge servers) on every street corner worldwide. When a user visits your site, the physically nearest food truck processes the request and returns data instantly. Latency virtually disappears.\nWhy Cloudflare Workers Is Hot Right Now: 3 Reasons 1. Blazing Speed Because programs run at the nearest edge location to each user, latency is minimized. Pages load instantly, providing app-like responsiveness.\n2. No Server Management Required No more OS updates, security patches, or memory monitoring. You just write the code you want to run — Cloudflare handles deployment and execution across its global network.\n3. Exceptional Cost Performance Traditional hosting charges fixed monthly fees whether you use resources or not. Serverless platforms like Cloudflare Workers bill you only for what you use. The free tier is generous enough that many small projects never need to pay.\nBest Use Cases Custom API servers: Lightweight programs connecting services (e.g., linking a time tracking system with LINE). Services with unpredictable traffic: Cloudflare\u0026rsquo;s massive network automatically distributes load, preventing crashes. Modern web frameworks: Tools like Hono are optimized for edge execution, delivering maximum performance. A Word of Caution: Migrating WordPress Requires Technical Effort If you want to migrate your WordPress blog to Cloudflare Workers, there are technical hurdles. WordPress is built for traditional centralized servers and databases. Currently, you would either optimize WordPress delivery through Cloudflare or rebuild your site using a headless CMS.\nSummary: From \u0026ldquo;Owning\u0026rdquo; to \u0026ldquo;Running at the Edge\u0026rdquo; Programs run near users worldwide (at the edge) No server maintenance — focus on writing code Perfect for APIs and traffic-heavy services Full WordPress migration has technical challenges The era of \u0026ldquo;rent, configure, and protect a server\u0026rdquo; is ending. If you are building a new web tool or API, consider Cloudflare Workers before signing up for traditional hosting.

SEO Is Slow, SNS Is Instant Google search rankings take weeks or months to build — like farming. SNS is like fireworks — post your article and followers click within seconds. This initial traffic boost also improves SEO rankings (synergy).\n2. Manual Sharing Hurts Consistency The hardest part of blogging is consistency. After writing, the few minutes needed for SNS posting often lead to \u0026ldquo;I\u0026rsquo;ll do it tomorrow\u0026rdquo; — and many articles never get shared. Automation eliminates this friction.\nKey Platforms for 2026 X (Twitter) — Still the King of Virality Despite API changes, X remains unmatched in Japan for real-time content distribution and viral reach.\nBluesky — The Rising Star Bluesky has exploded in popularity since late 2025. With a familiar interface and developer-friendly open API, it is a top priority for tech and creator audiences.\n3 Auto-Posting Methods 1. External Automation Tools (Zapier, Make) Pros: Complex conditional workflows across multiple apps Cons: Free tiers have strict limits; expensive for frequent posting 2. Dedicated SNS Management SaaS Pros: Scheduled posting, analytics Cons: Monthly fees; granting third-party access to your accounts 3.

The most common cyber attack today is credential stuffing.\nHere is how it works: A minor site you signed up for years ago gets hacked, and your email and password leak. Hackers then use automated programs (bots) to try that same combination on Amazon, Rakuten, banks, and social media sites worldwide.\nIf you reuse passwords everywhere, a single breach from one minor site can lead to complete domino-effect destruction — someone shopping on your Amazon account, hijacking your social media, and stealing your credit card info.\nThe Savior: Password Manager Apps \u0026ldquo;I know I shouldn\u0026rsquo;t reuse passwords, but remembering 50 different complex passwords is impossible!\u0026rdquo;\nExactly right. That is where password manager apps come in.\nThink of it as an ultra-secure vault on the internet:\nThe app generates long, complex passwords like aB3#kL9z!pQ for each site All those complex passwords are stored inside the vault You only need to remember one master password to open the vault When you visit a login page, the app automatically fills in the correct password.

The basic plan is completely free, syncing unlimited passwords across all your devices (iPhone, Android, Windows, Mac). It is open-source, meaning security experts worldwide can inspect the code.\n2. 1Password — Premium Design and Support If you prefer a paid service (a few dollars per month) for the best user experience, 1Password is extremely popular. Beautiful design, excellent auto-fill, and trusted by professionals worldwide.\n3. Built-in Options: Apple / Google If installing a new app sounds like work, built-in options like iCloud Keychain (iPhone) or Google Password Manager (Chrome) are a good starting point. They may lack advanced features, but they stop password reuse effectively.\nOne Critical Warning: Protect Your Master Password Your master password is the key to your vault. You must never forget it and never share it.\nMake it a long, memorable phrase (e.g., \u0026ldquo;I-love-eating-Ramen-every-Sunday-in-Tokyo!\u0026rdquo;) Enable 2-factor authentication (2FA) so a second code is needed to open the vault Summary: New Year, New Security Habits Reused passwords are prime targets for credential stuffing A password manager means remembering just ONE password Start with free options like Bitwarden Secure your master password and enable 2FA Security sounds complex, but once set up, logging in becomes a one-second face or fingerprint scan. You gain both safety and daily convenience.\nYour next step: Download Bitwarden on your phone today. Change one important password to something complex and save it in the app. That small step will protect your digital assets for years to come.\n","date":"2026-02-10T18:40:00Z","image":"/img/thumbnail/password-manager-beginners-guide-en.png","permalink":"/en/web/password-manager-beginners-guide/","title":"Stop Reusing Passwords Today: The Beginner's Guide to Password Managers (2026)"},{"content":"\u0026ldquo;Are you paying for server fees, domain costs, and phone bills with your personal credit card?\u0026rdquo;\n\u0026ldquo;You want a business card, but the annual fee worries you?\u0026rdquo;\nIf you are just starting out as a freelancer or running a side business, you might be struggling with money management.\nJust as you should keep a separate business bank account, separating your credit cards into personal and business use is critically important.\nIf you are currently paying business expenses with your personal card, you are not only making tax filing harder but also missing out on thousands of dollars worth of points.\nIn this guide, we explain how to choose the best business credit card based on 2026 trends, including the popular \u0026ldquo;gold card training\u0026rdquo; strategy for maximum rewards.\nWhy You Need a Separate Business Credit Card You might think, \u0026ldquo;As long as the bank account is separate, the card can stay personal.\u0026rdquo; But having a dedicated business card offers two major advantages.\n1. Fully Automated Bookkeeping Connect your business credit card to cloud accounting software (like freee or Money Forward), and all business expenses are automatically recorded in your books.\nIf personal and business expenses are mixed, you will face the nightmare of manually sorting each transaction. Separating cards eliminates this hassle entirely.\n2. Earn Points on Business Expenses As your business grows, expenses like computer purchases and SaaS subscriptions add up significantly.\nBy charging all of these to a high-reward card, you can easily earn tens of thousands of points per year. Use those points for new gadgets or office supplies — it is essentially free expense reduction.\nThe 2026 Trend: Smart Selection and the \u0026ldquo;1 Million Yen Training\u0026rdquo; What kind of card should you choose? Status cards are out; practicality (point rewards vs. annual fee balance) is the 2026 trend.\nTarget No-Fee or Conditional Fee Cards While your income is still unstable, there is no need to pay high annual fees for premium cards. Start with no-fee cards or cards where meeting certain conditions waives the annual fee from the next year onward.\nThe Popular \u0026ldquo;1 Million Yen Training\u0026rdquo; Have you heard of the \u0026ldquo;1 Million Yen Training\u0026rdquo; trend on social media?\nThis is a program offered by certain credit cards (like Mitsui Sumitomo Gold (NL), Aeon Gold, or Epos Gold): spend 1 million yen or more annually, and the annual fee is permanently waived.\nSpending 1 million yen on personal expenses alone is tough, but including business expenses — server fees, advertising, inventory, computer purchases — many freelancers cross that threshold fairly easily.\nOnce you complete the \u0026ldquo;training,\u0026rdquo; you enjoy gold card benefits (airport lounge access, higher point rewards) for free forever — an incredibly cost-effective strategy.\nRecommended Card Lineups by Purpose Choose a card based on your lifestyle and the services you frequently use.\n1. For the Rakuten Ecosystem: Rakuten Business Card If you shop on Rakuten and use Rakuten Bank for your business account, the Rakuten business card is ideal. Earn Rakuten points on all business expenses and use them for personal shopping.\n2. For Mobile-First Payments: Olive (SMBC) For those who want to handle everything with smartphone touch payments, flexible pay services like Mitsui Sumitomo Bank\u0026rsquo;s \u0026ldquo;Olive\u0026rdquo; are gaining popularity. With an integrated bank account and credit card, fund transfers and point management are handled in a single app — perfect for tech-savvy freelancers.\nA Word of Caution: Don\u0026rsquo;t Overspend for Points The most important thing to remember: do not buy things you do not need just to earn points or hit spending targets.\nPoints are a bonus, not the goal. Increasing unnecessary expenses weakens your business. Stay disciplined and only charge genuinely necessary investments to your card.\nSummary: Apply for a Card Alongside Your Bank Account Separate cards for accounting automation and points If you expect 1 million yen in annual expenses, try the gold card training Choose based on your ecosystem (Rakuten, mobile payments, etc.) January is the perfect time to set up a new year\u0026rsquo;s bookkeeping. Open a business bank account and apply for a business credit card at the same time. This is the first step to making this year\u0026rsquo;s tax filing dramatically easier.\n","date":"2026-02-05T18:37:00Z","image":"/img/thumbnail/freelance-creditcard-strategy-en.png","permalink":"/en/life/freelance-creditcard-strategy/","title":"The Ultimate Guide to Business Credit Cards for Freelancers in 2026"},{"content":"\u0026ldquo;Spent hours writing a great article, but it loads so slowly nobody reads it\u0026hellip;\u0026rdquo; \u0026ldquo;PageSpeed Insights shows a red score on mobile — embarrassing.\u0026rdquo;\nSite speed is not just about comfort — Google uses page load speed as a ranking factor (SEO). A slow site hurts both user experience and search visibility.\n\u0026ldquo;Speeding up a site sounds like engineering work.\u0026rdquo; Not necessarily. With the right plugin settings and a few image tricks, anyone can dramatically improve speed.\nThis guide covers 5 proven steps that professionals use, explained for beginners.\nWhy Your WordPress Site Is Slow: 3 Main Causes 1. Images Are Too Large Smartphone and camera photos are incredibly high resolution. If you upload them directly, a single 5MB photo can cripple load times.\n2. Too Many Plugins Too many plugins — especially unused or overlapping ones — continuously consume server resources.\n3. Caching Is Not Properly Configured WordPress builds pages from scratch on every visit by querying the database. Caching stores a ready-made copy for faster delivery.\nStep 1: Measure Your Current Score Use Google\u0026rsquo;s free PageSpeed Insights: https://pagespeed.web.dev/\nEnter your URL and click Analyze. Don\u0026rsquo;t worry if the score is low — that means room for improvement! Focus on the mobile score.\nStep 2: Convert Images to Next-Gen Formats Use WebP or AVIF Formats like WebP and AVIF are dramatically smaller than JPEG or PNG with minimal quality loss.\nAction: Install a plugin like EWWW Image Optimizer or Converter for Media to automatically convert past and future images.\nEnable Lazy Load Lazy loading means images only load when they scroll into view. WordPress has this built-in since version 5.5, but caching plugins offer more control.\nStep 3: Install a Caching Plugin LiteSpeed Cache (for LiteSpeed servers) If your host uses LiteSpeed (common with Lolipop, ConoHa WING, CoreServer V2, etc.), install LiteSpeed Cache for server-level caching.\nWP Fastest Cache / WP Super Cache (for other servers) For Apache/Nginx servers, WP Fastest Cache offers simple checkbox-based setup.\nImportant: Only use ONE caching plugin. Multiple plugins conflict and can break your site.\nStep 4: Clean Up Unnecessary Data Delete unused plugins (not just deactivate — delete) Remove post revisions: Use WP-Optimize to clean up accumulated revisions bloating the database Step 5: Consider a CDN (Intermediate) For further improvement, use a CDN like Cloudflare. It distributes your content worldwide, reducing server load and latency. This is especially helpful for traffic spikes and international visitors. Complete steps 1-4 first before tackling CDN setup.\nSummary: Speed Is Hospitality for Your Readers Measure your current score Convert and compress images to WebP Install the right caching plugin Remove unused data Consider a CDN if needed A 1-second improvement in load time reduces bounce rates and increases conversions. Start with the easiest step — image optimization — and watch your site transform.\n","date":"2026-01-05T07:00:00Z","image":"/img/thumbnail/webpage-speed-up-en.png","permalink":"/en/web/webpage-speed-up/","title":"WordPress Too Slow? 5 Proven Steps to Score 90+ on PageSpeed Insights"},{"content":"\u0026ldquo;I understand AI is useful, but I\u0026rsquo;m uneasy about entering sensitive work data\u0026hellip;\u0026rdquo; \u0026ldquo;Monthly AI subscription fees are quietly eating into my budget.\u0026rdquo;\nAs generative AI becomes part of daily life, many users face these concerns. In 2026, the hottest trend in IT is Local AI (Local LLM) — running AI directly on your own PC without relying on cloud servers.\nThis guide explains what local AI is, how it differs from cloud-based AI, and why it is suddenly gaining traction.\nWhat Is Local AI? Cloud-based AI (like ChatGPT) sends your questions to a supercomputer on the internet, which processes them and returns results.\nLocal AI means downloading the AI model itself to your own computer and running it entirely on your hardware.\nWhy Is Local AI Trending Now? Running AI on your PC has been technically possible for years, but it required expensive, powerful computers and programming expertise. In 2026, the situation has changed dramatically. Lightweight, efficient AI models have emerged alongside user-friendly tools, making local AI practical on consumer hardware.\nThe Biggest Advantages: Privacy and Cost 1. Handle Sensitive Data Safely Because local AI can run offline, nothing is sent to external servers. This is revolutionary for:\nUnpublished business documents Customer personal information Password management code You can analyze and summarize these without any risk of data leakage.\n2. No Server Outages or Service Shutdowns No more \u0026ldquo;the AI server is down and I can\u0026rsquo;t access it when I need it.\u0026rdquo; Once downloaded, your AI works anywhere — on a plane or a mountain campsite.\n3. No Monthly Fees Most local AI models are open-source and free. You only pay for the electricity to run your PC.\nLightweight Models and Easy Tools The trend is driven by new models like DeepSeek, which deliver high-quality text and code generation with less computation. Tools like Ollama let you install and run local AI as easily as a regular app — no command-line expertise required.\nOne Caveat: PC Specs Matter Local AI requires processing power. You need at least 16GB of RAM (32GB+ for a smooth experience) and a capable GPU. Older office laptops may be too slow to be practical.\nSummary: 2026 Is the Year AI Comes Home Local AI runs entirely on your PC Zero data leakage risk DeepSeek and Ollama make it accessible A reasonably powerful PC is required The next step is choosing between cloud and local AI based on your needs. Check your PC\u0026rsquo;s RAM — if you have 16GB or more, you can start exploring local AI today!\n","date":"2026-01-01T18:33:00Z","image":"/img/thumbnail/local-llm-en.png","permalink":"/en/web/local-llm/","title":"Beyond ChatGPT: Why Local AI on Your Own PC Is the Breakthrough Trend of 2026"},{"content":"\u0026ldquo;Is your phone charging slower than usual?\u0026rdquo;\n\u0026ldquo;Is your laptop charger too heavy to carry around?\u0026rdquo;\nDo you feel a little stress every time you charge your phone or computer?\nIn recent years, the world of chargers has undergone a revolution.\nIf you are still using the old charger that came with your phone or a cheap cable from a dollar store, you might be wasting precious time.\nWith the latest technology, what used to take 2 hours can now be done in 30 minutes, and brick-heavy laptop adapters can be reduced to the size of an egg.\nIn this article, we explain USB Power Delivery (PD) and Gallium Nitride (GaN) — two technologies you need to know about — in simple terms without jargon.\nBy the end, your bag will be dramatically lighter, and you will be free from the frustration of waiting for devices to charge.\nNot All USB-C Cables Are the Same Modern smartphones and PCs are increasingly adopting the oval-shaped USB Type-C connector.\n\u0026ldquo;Doesn\u0026rsquo;t any cable work as long as the plug fits?\u0026rdquo;\nThat is a common misconception — and a big trap.\nUSB-C is just the shape of the connector. The performance varies widely:\nData-only cables (extremely slow charging) Standard charging cables (fine for phones) Fast-charging cables (can handle laptops) They all look the same, but what is inside is completely different. This is the real reason many people experience slow charging.\nKeyword 1: PD (Power Delivery) — The Fast Charging Standard To dramatically speed up charging, you need USB Power Delivery (PD).\nTraditional USB chargers (like the old square iPhone charger) can only output about 5W. In hose terms, that is a trickle.\nWith PD-compatible chargers and cables, you can deliver 20W-30W for phones and 60W-100W for laptops — a completely different level of power.\nThis is how fast charging can reach 50% or more in just 30 minutes.\nKeyword 2: GaN (Gallium Nitride) — Making Heavy Adapters a Thing of the Past \u0026ldquo;Powerful chargers must be big and heavy, right?\u0026rdquo;\nThat used to be true a few years ago. But then came GaN (Gallium Nitride), a new material.\nTraditional chargers use silicon, but GaN generates less heat and is more energy efficient.\nAs a result, we can now create chargers the size of a small dice that can still power a laptop.\nGoing forward, choosing a charger labeled \u0026ldquo;GaN\u0026rdquo; is the smart move.\n3 Tips for Choosing the Right Charging Setup So what should you buy? Here are three key points.\n1. Choose a 45W-65W GaN Charger In the world of charging, bigger capacity covers more needs.\n20W is enough for a phone, but you might buy a tablet or laptop later. We recommend a 45W-65W GaN charger that can handle both phones and PCs.\n2. Choose a PD-Compatible, 100W-Capable Cable Even with a powerful charger, a thin cable is like a narrow pipe — it defeats the purpose.\nLook for cables labeled \u0026ldquo;PD compatible\u0026rdquo; or \u0026ldquo;100W compatible\u0026rdquo;. Cheap dollar-store cables are often not PD-compatible, so be careful.\n3. Two Ports Are Convenient At a cafe or on the Shinkansen, there is often only one outlet.\nA charger with two USB-C ports lets you charge your phone and earbuds, or your phone and laptop, simultaneously — very convenient.\nWarning: Discard Old Cables We do not recommend using old spare cables you have lying around.\nUsing outdated, incompatible cables not only slows charging but can also cause heat-related issues.\nWhen upgrading your charging setup, get rid of old cables and standardize on reliable PD-compatible cables.\nSummary: Investing in Your Charging Setup Is the Best Time-Saving Hack Not all USB-C cables are the same PD support enables blazing-fast charging GaN makes chargers incredibly small and light Upgrading your charger and cable costs around $30-50 total.\nBut considering the daily time saved from waiting for charges and the freedom from heavy luggage, there is no better cost-performance investment.\nTry upgrading your charging setup today!\n","date":"2025-12-17T03:00:00Z","image":"/img/thumbnail/charge-speed-up-en.png","permalink":"/en/life/charge-speed-up/","title":"Slow Charging?

They do not distinguish between personal blogs and major sites. Any site with weak security is a target.\nIf your site gets hijacked, attackers could inject spam links, steal visitor data, or even delete your entire site. Years of hard work could vanish instantly.\n\u0026ldquo;But I don\u0026rsquo;t have technical expertise\u0026hellip;\u0026rdquo;\nNo problem. WordPress security can be surprisingly robust with just plugins and a few settings. This guide covers 5 essential steps to prevent unauthorized access, explained for beginners.\nWhy WordPress Is a Target WordPress powers over 40% of all websites. To hackers, it is like the world\u0026rsquo;s most common lock — find one vulnerability and you can attack hundreds of millions of sites.\nThe most common attack is brute force — automated bots trying thousands of password combinations on your login page. Defending against this is your first priority.\nStep 1: Change Your Login Page URL WordPress\u0026rsquo;s biggest weakness: the login page location is the same for every site. Usually it is at /wp-admin or wp-login.php. That is like publishing your front door address worldwide.\nAction: Use a plugin like SiteGuard WP Plugin (made in Japan) or WPS Hide Login to change your login URL to something unique (e.g., yoursite/secret-door-123). This alone blocks over 90% of automated attacks.\nStep 2: Remove the \u0026ldquo;admin\u0026rdquo; Username If your username is still \u0026ldquo;admin,\u0026rdquo; change it immediately. Hackers assume the username is admin. All they need to do is guess the password.\nAction:\nGo to Users \u0026gt; Add New in the WordPress admin Create a new user with Administrator role and a unique username Log out, log in with the new account Delete the old \u0026ldquo;admin\u0026rdquo; user (assign existing posts to the new user) Step 3: Limit Login Attempts Lock the account after a few failed login attempts. WordPress has no built-in limit, allowing bots to try millions of passwords.\nAction: SiteGuard WP Plugin includes this feature. Alternatively, use Limit Login Attempts Reloaded.\nStep 4: Enable 2-Factor Authentication (2FA) This is the ultimate shield. Even if your password leaks, an attacker cannot log in without the one-time code from your phone.\nAction: Install Wordfence Login Security or WP 2FA. After setup, logging in will require scanning a QR code with your phone authenticator app.\nStep 5: Keep Everything Updated WordPress update notifications are not just about new features — they announce security vulnerability fixes. Ignoring updates is like leaving a hole in your wall unpatched.\nAction: When you see an update notification, back up your site and apply the update immediately.\nSummary: Security Is Insurance — Start Before Something Happens Change your login URL Remove the \u0026ldquo;admin\u0026rdquo; user Limit login attempts Enable 2FA Keep everything updated Set these up once, and they will protect your site automatically. Don\u0026rsquo;t rely on baseless confidence — install at least one security plugin today. That small action could save your digital assets.\n","date":"2025-12-04T07:00:00Z","image":"/img/thumbnail/wordpress-security-en.png","permalink":"/en/web/wordpress-security/","title":"5 Essential Steps to Secure Your WordPress Site from Hackers"},{"content":"\u0026ldquo;Suddenly I can\u0026rsquo;t access a site I visit every day\u0026hellip;\u0026rdquo; \u0026ldquo;My blog is showing a \u0026lsquo;502 Bad Gateway\u0026rsquo; error!\u0026rdquo;\nIf multiple sites are down simultaneously, it could be a Cloudflare outage. Cloudflare handles nearly 20% of global web traffic — it is a massive intersection on the internet. When an incident occurs here, countless sites become unreachable worldwide.\nThis guide explains how to check if Cloudflare is experiencing an outage and what steps both users and site administrators should take.\nWhat Is Cloudflare and Why Do Outages Happen? Cloudflare acts as both a shield (security) and an accelerator (speed) for websites. When you visit a Cloudflare-protected site, your request goes through Cloudflare\u0026rsquo;s servers first. This blocks malicious traffic and distributes load.\nBut Cloudflare is a massive global network. Configuration errors, hardware failures, or large-scale attacks can occasionally cause outages. When the shield fails, visitors cannot reach the site even if the origin server is fine.\n3 Steps to Check If Cloudflare Is Down 1. Check the Official System Status Page\nCloudflare System Status: https://www.cloudflarestatus.com/\nIf you see \u0026ldquo;All Systems Operational\u0026rdquo; in green, the issue is likely not on Cloudflare\u0026rsquo;s end. Red or yellow alerts like \u0026ldquo;Major Outage\u0026rdquo; indicate a Cloudflare problem.\n2. Use DownDetector\nSites like DownDetector show user reports in real-time. A spike in reports confirms you are not alone.\n3. Search on X (Twitter)\nSearch for \u0026ldquo;Cloudflare down\u0026rdquo; or \u0026ldquo;Cloudflare outage\u0026rdquo; — global services get reported quickly.\nCommon Error Screens Error 502 Bad Gateway / 504 Gateway Timeout: Communication failure between Cloudflare and the origin server. Error 520 Web Server Is Returning an Unknown Error: Unexpected response from the server. Error 521 Web Server Is Down: Cloudflare could not connect to the server. What to Do During an Outage For Visitors Wait: Engineers are working on recovery. Most outages resolve in minutes to hours. Hard Refresh: Press Ctrl+F5 (Cmd+Shift+R on Mac) to clear cached error pages. Switch Networks: Try switching from Wi-Fi to mobile data. For Site Administrators Check Cloudflare Status first: If it is a global outage, do NOT change any settings — wait for recovery. Verify your server: Use SSH or your hosting dashboard to confirm your server is running. Consider disabling Cloudflare proxy (with caution): Turning off the proxy (gray cloud) bypasses Cloudflare but exposes your IP and disables security features. Summary When sites are unreachable, check Cloudflare Status first. 502 errors signal communication trouble between Cloudflare and the server. During major outages, both users and admins should wait for recovery. Bookmark the Cloudflare Status page for quick reference!\n","date":"2025-11-21T05:29:19Z","image":"/img/thumbnail/cloudflare-downtime-en.png","permalink":"/en/web/cloudflare-downtime/","title":"Can't Access Certain Sites?

The Toll Booth Effect Traditional internet connections (called PPPoE) are like highway toll booths. Everyone must pass through a single authentication point to reach the wider internet. During off-peak hours, traffic flows smoothly. But at night and on weekends, cars (data) flood the toll booth, causing massive congestion. That is why your connection slows down in the evening.\nThe Solution: IPv6 IPoE The new connection standard, IPv6 IPoE, is like taking a bypass road that connects directly to the internet. This road is wider and has no toll booths (authentication points), so speeds remain fast even during peak hours.\nHow to Check Your Current Connection On a Wi-Fi connected device, visit an \u0026ldquo;IPv6 connection check\u0026rdquo; site (search for \u0026ldquo;IPv6 check\u0026rdquo;). If you see \u0026ldquo;v6 Plus\u0026rdquo; or \u0026ldquo;IPoE\u0026rdquo; displayed, you are already using the new standard. If you see \u0026ldquo;PPPoE\u0026rdquo; or \u0026ldquo;IPv4 only\u0026rdquo;, you are still on the old, congested connection. Two Requirements for IPv6 IPoE 1. Check Your ISP Contract Most fiber optic services (like Docomo Hikari, SoftBank Hikari, Rakuten Hikari) support IPv6 IPoE by default, but you may need to enable a free option. Check your provider\u0026rsquo;s member portal for \u0026ldquo;v6 Plus\u0026rdquo; or \u0026ldquo;IPv6 Option.\u0026rdquo;\n2. Use a Compatible Router Even with the right contract, your router must support the new standard. Routers purchased in the last few years are mostly compatible, but routers over 5 years old may not be. Look for \u0026ldquo;IPv6 IPoE compatible\u0026rdquo; or \u0026ldquo;v6 Plus\u0026rdquo; on the packaging.\nSummary: Check Your Contract Before Buying a New Router \u0026ldquo;Wi-Fi is slow, so I bought an expensive router — but it didn\u0026rsquo;t get any faster!\u0026rdquo; This is often caused by the connection type, not the router.

It wasn\u0026rsquo;t your phone or Wi-Fi — it was a global-scale Cloudflare outage that disrupted countless services.\nHere is the timeline, the surprising cause, and what we can learn from it.\n1. Timeline of the \u0026ldquo;3 Hours of Silence\u0026rdquo; Incident Time and Impact Date: November 18, 2025 (Tue), from around 20:20 JST Symptoms: \u0026ldquo;502 Bad Gateway\u0026rdquo; errors, apps failing to load Major services affected: X (Twitter) ChatGPT (OpenAI) Discord Canva Spotify Millions of other websites globally DownDetector charts spiked vertically — it was an unprecedented event.\nWhy Did Everything Go Down at Once? All these services relied on Cloudflare\u0026rsquo;s security infrastructure. Cloudflare is like a massive traffic intersection — when all the traffic lights turned red simultaneously, every vehicle on every road ground to a halt.\n2. The Cause: Not a Cyber Attack Surprisingly, the cause was an internal system bug — not a cyber attack.\nThe Culprit: A Bot Protection Configuration File Cloudflare\u0026rsquo;s \u0026ldquo;Bot Management\u0026rdquo; feature uses configuration files to block malicious bots. During an update, the feature file grew unexpectedly large due to unforeseen system behavior. When Cloudflare\u0026rsquo;s global servers tried to load this enormous file, they crashed.\nIronically, an update meant to enhance security ended up taking down the system.\n3. Lessons and Countermeasures What Users Can Do Recognize it is not just you: Check Cloudflare Status or news sites. Knowing it is a global issue saves you from pointless router restarts. Wait for recovery: Infrastructure-level outages can only be fixed by engineers on the other end. What Site Operators Can Do Don\u0026rsquo;t make unnecessary changes: Changing server settings or DNS during an outage can cause secondary issues after recovery. Have emergency communication channels: Maintain multiple ways (SNS, email newsletters) to inform users if your site goes down — especially since X might also be down. Summary This outage highlighted the fragility of an internet where so many services depend on a single company\u0026rsquo;s infrastructure. But it also demonstrated the rapid response of Cloudflare\u0026rsquo;s engineering team.\nCause: A bug from an oversized bot protection configuration file Not a cyber attack Fully recovered For those interested in more technical details, Cloudflare\u0026rsquo;s official blog post is available.\n","date":"2025-11-19T06:00:00Z","image":"/img/thumbnail/cloudflare-incident-2025-11-18-en.png","permalink":"/en/web/cloudflare-incident-2025-11-18/","title":"Nov 18, 2025: Massive Cloudflare Outage Took Down X, ChatGPT, Discord — What Happened?"},{"content":"Videos buffering endlessly. Your voice cutting out during web meetings. Nothing is more frustrating than a slow or unreliable Wi-Fi connection.\n\u0026ldquo;I don\u0026rsquo;t know anything about networking settings, and calling support sounds like a hassle\u0026hellip;\u0026rdquo; \u0026ldquo;It was working fine yesterday — why is it suddenly slow?\u0026rdquo;\nMany people struggle with these exact problems. But the good news is that Wi-Fi issues can often be resolved with some simple checks, no technical expertise required. In this guide, we will walk through the common causes of slow or unstable Wi-Fi and the specific steps you can take to fix them.\nBy the end, you will be able to diagnose and resolve Wi-Fi problems on your own and get back to enjoying a smooth internet experience.\n5 Common Reasons Why Wi-Fi Is Slow or Unstable Let us start by understanding the enemy. Here are the five most common causes.\nCause 1: Temporary Glitch in Your Router or Device This is the most common and easiest problem to fix. Wi-Fi routers are essentially small computers that run 24/7. Like any computer, they can become sluggish from heat buildup or processing congestion — think of it as your router being \u0026ldquo;tired.\u0026rdquo;\nCause 2: Poor Router Placement Wi-Fi signals are invisible waves that weaken when they encounter obstacles.\nDeep inside a shelf or corner of the room Near aquariums or vases (water absorbs signals) Inside metal cabinets (metal reflects and blocks signals) Near microwaves and other appliances (signal interference) If your router is in any of these locations, signals weaken before reaching your devices, causing slowdowns and disconnections.\nCause 3: Too Many Devices Connected Simultaneously A Wi-Fi router can only handle so much data at once. Think of it like road capacity. When every family member\u0026rsquo;s phone, laptop, TV, gaming console, and smart home devices are connected at the same time, the road gets congested and traffic slows to a crawl.\nCause 4: Crowded Frequency Band Wi-Fi uses two main frequency bands: 2.4GHz and 5GHz.\n2.4GHz: Good range and wall penetration, but prone to congestion from other devices (microwaves, Bluetooth) 5GHz: Faster speeds with less interference, but shorter range and weaker through obstacles If your neighbors are also using 2.4GHz heavily, interference can cause slowdowns.\nCause 5: Outdated Router or Standards \u0026ldquo;Have you been using the same router for over 5 years?\u0026rdquo; The router itself may not keep up with modern high-speed internet or your latest devices.\nWi-Fi standards have evolved from Wi-Fi 4 (11n) to Wi-Fi 5 (11ac) to Wi-Fi 6 (11ax). An older router can bottleneck your connection even if you pay for fast fiber optic internet.\n7 Easy Ways to Dramatically Improve Your Wi-Fi Now for the practical steps, from simplest to slightly more advanced. Try them one at a time.\nFix 1: Restart Your Router and Devices This is the single most effective first step. Restarting clears temporary issues and refreshes the system.\nProper restart procedure:\nTurn off all connected devices (or disable Wi-Fi) Unplug the router\u0026rsquo;s power adapter from the outlet Wait at least 1 minute (let it fully discharge) Plug the router back in and wait a few minutes for it to boot up Turn your devices back on and reconnect You will be surprised how often this alone fixes the problem.\nFix 2: Relocate Your Router The ideal spot is near the center of your home, 1-2 meters above the floor.\nDon\u0026rsquo;t put it: on the floor, behind the TV, inside cabinets, near metal or water Do put it: on a shelf or desk in a central, open area Think of the router\u0026rsquo;s antennas broadcasting in all directions and find a clear spot.\nFix 3: Switch Wi-Fi Bands Many routers broadcast two network names (SSIDs). For example, \u0026ldquo;WiFi-A\u0026rdquo; and \u0026ldquo;WiFi-G\u0026rdquo;.\nNames ending in -A or -5G → 5GHz (fast but shorter range) Names ending in -G or -2.4G → 2.4GHz (slower but better range) If you are near the router, connect to the 5GHz band for faster speeds. If you are far away, the 2.4GHz band may be more stable.\nFix 4: Disconnect Unused Devices Old tablets, guest laptops, smart speakers — devices you are not actively using may still be connected and consuming bandwidth. Check your router\u0026rsquo;s connected device list and disconnect anything unnecessary.\nFix 5: Update Router Firmware Firmware is the operating system running your router. Manufacturers release updates to fix bugs and improve security. Many modern routers update automatically, but older models may require manual updates.\nFix 6: Check Your LAN Cable One often-overlooked issue: the Ethernet cable connecting your modem to the router may be loose or outdated. Ensure both ends are firmly connected. If the cable is marked \u0026ldquo;CAT5\u0026rdquo; or older, consider upgrading to CAT5e or CAT6 for better speeds.\nFix 7: Avoid Channel Congestion This is slightly more advanced but highly effective. 2.4GHz is especially prone to interference from neighboring networks using the same channel. Check your router\u0026rsquo;s settings to ensure the Wi-Fi channel is set to \u0026ldquo;Auto.\u0026rdquo;\nIf Nothing Works: Consider Upgrading If you have tried all seven steps and the problem persists, your hardware may have reached end of life.\nCheck 1: Is Your Router Too Old? Wi-Fi routers typically have a lifespan of 4-5 years.\nUsing the same router for 5+ years? Fast internet plan but slow Wi-Fi? Many new devices added recently? If any of these apply, upgrading to a Wi-Fi 6 or Wi-Fi 6E router can dramatically improve performance.\nCheck 2: Is Your Internet Plan the Bottleneck? Even with the latest router, a slow internet connection limits speeds. If your connection is especially slow during peak evening and weekend hours, your provider or connection type (PPPoE) may be congested. Consider switching to IPv6 IPoE for a faster, less congested connection.\nSummary: Start with Simple Checks Here is a quick recap of the most effective first steps:\nRestart your router and devices Relocate your router to a better position Switch between 5GHz and 2.4GHz bands These three steps alone can resolve most Wi-Fi issues. Don\u0026rsquo;t let slow internet ruin your day — try these fixes and reclaim your smooth online experience.\n","date":"2025-11-07T06:00:00Z","image":"/img/thumbnail/wifi-refresh-en.png","permalink":"/en/life/wifi-refresh/","title":"Wi-Fi Too Slow or Not Connecting?

MLIT determined that numerous post offices nationwide had violated the law by failing to conduct proper driver safety check-ins and safety confirmation procedures.\nWhy does this event have such significant implications for Yu-Pack\u0026rsquo;s future? Let us break it down.\nApproximately 2,500 Vehicles Grounded Japan Post operated about 2,500 vehicles under its own freight transport permit. These vehicles formed the backbone of Yu-Pack and other mail delivery — the \u0026ldquo;spine\u0026rdquo; of the logistics network spanning trunk line transport and regional collection/distribution.\nWith the permit revoked, Japan Post can no longer operate these trucks itself. This means a substantial portion of its transportation capacity is gone, potentially crippling the nationwide delivery network.\nCan Outsourcing Bridge the Gap? Reports suggest Japan Post plans to weather the crisis by outsourcing to its subsidiary \u0026ldquo;Japan Post Transport\u0026rdquo; and partner companies like Sagawa Express and Yamato Transport.\nHowever, Japan\u0026rsquo;s logistics industry is already struggling with the \u0026ldquo;2024 Problem\u0026rdquo; — a severe shortage of drivers and tighter labor regulations. If Japan Post \u0026ldquo;dumps\u0026rdquo; thousands of vehicles\u0026rsquo; worth of transportation demand onto an already strained system, partners may exceed capacity, leading to delivery delays.\nThe \u0026ldquo;2024 Problem\u0026rdquo; refers to the capacity crunch caused by new labor reform laws capping drivers\u0026rsquo; overtime, reducing the entire industry\u0026rsquo;s delivery capacity.\nYu-Pack\u0026rsquo;s Reliability at Risk Yu-Pack has been trusted for its reliability — \u0026ldquo;delivered on time,\u0026rdquo; \u0026ldquo;consistent service nationwide,\u0026rdquo; and \u0026ldquo;convenient drop-off at post offices.\u0026rdquo; If this crisis leads to delivery delays and confusion, consumers may start feeling uneasy about using Yu-Pack.\nBusinesses that rely on speed and accuracy, especially e-commerce, may begin avoiding Yu-Pack. This would not only impact Japan Post\u0026rsquo;s revenue but also devalue the Yu-Pack brand itself.\nPotential Service Cuts and Price Hikes If logistics capacity is reduced, deliveries to remote areas may become difficult, potentially leading to service termination in some regions. Additionally, increased outsourcing costs may force nationwide price hikes. Japan Post has adjusted Yu-Pack pricing in the past due to fuel cost increases.\nSummary: Can Japan Post Protect Yu-Pack\u0026rsquo;s Future? This permit revocation is not just a legal compliance issue — it has profound implications for Japan\u0026rsquo;s postal and logistics infrastructure. Many people are beginning to worry whether Yu-Pack, a service deeply embedded in daily life, can continue.\nAll eyes are on how Japan Post will rebuild trust and restructure its logistics network. As users, we should keep a close watch on delivery status and service changes in the coming months.\nThank you for reading!

The Impact of Japan Post's Permit Revocation"},{"content":"Hello!\nOn June 5, 2025, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) decided to revoke Japan Post\u0026rsquo;s general freight motor carrier permit. The decision stems from widespread failures to properly conduct driver safety check-ins at post offices nationwide. This action will ground approximately 2,500 trucks and vans, severely impacting Japan Post\u0026rsquo;s logistics operations.\nThe Reality of the Safety Violations MLIT audits found that over 60% of the 119 inspected post offices had inadequate driver check-in procedures, violating the Motor Truck Transportation Business Law. Violations included failure to verify alcohol detector use and check-in frequencies falling well below legal requirements.\nThese safety management failures posed serious accident risks, leading MLIT to impose the harshest administrative penalty available — permit revocation.\nImpact and Future Response With approximately 2,500 vehicles grounded, Japan Post\u0026rsquo;s logistics operations — particularly the \u0026ldquo;Yu-Pack\u0026rdquo; parcel service — face significant disruption. In fiscal 2023, the company handled about 1 billion parcels, commanding roughly 20% market share.\nAfter the revocation, Japan Post cannot reapply for the same permit for five years. The company plans to maintain operations by increasing reliance on its subsidiary \u0026ldquo;Japan Post Transport\u0026rdquo; and partner companies.\nSummary The revocation of Japan Post\u0026rsquo;s transport permit is an extremely rare penalty against a major carrier, with serious implications for its logistics network.

However, its meteoric rise is accompanied by mounting controversies over data misuse, security concerns, and more. Here is a breakdown of the key allegations.\n1. Unauthorized Use of Google AI Data? DeepSeek\u0026rsquo;s latest model, \u0026ldquo;DeepSeek-R1-0528,\u0026rdquo; released in May 2025, shows strong performance in math, programming, and reasoning. However, AI researchers suspect some training data was taken without authorization from Google\u0026rsquo;s Gemini model. DeepSeek has not disclosed detailed training data sources, raising transparency concerns.\n2. Evading US Export Controls? The US Congress has launched an investigation into whether DeepSeek evaded export controls to illegally obtain advanced Nvidia AI chips. Reports suggest DeepSeek acquired approximately 60,000 Nvidia chips for AI development. If confirmed, this would pose a significant threat to US national security.\n3. User Data Sent to China Security researchers revealed that DeepSeek\u0026rsquo;s AI app transmitted user login information and chat history to Chinese state-owned telecom companies and ByteDance (TikTok\u0026rsquo;s parent). In response, countries including South Korea, Australia, and Canada have banned DeepSeek use in government agencies and suspended new downloads.\n4.

According to recent reports, Nintendo has begun gradually releasing specific information about the next-generation console. This new development will have a significant impact on the entire gaming industry.\nThe reason is that the Switch was a huge hit thanks to its innovative hybrid design.

First, what\u0026rsquo;s required of the Nintendo Switch successor is improved performance. In particular, graphics performance improvements are expected, which will enable more realistic gaming experiences. Extended battery life and more comfortable controls are also important points.\nOn the other hand, a challenge is whether existing Switch users will transition to the new model. Based on past experience, there are concerns that the value of the current console may decrease when a successor is released. Therefore, Nintendo needs to implement measures that allow users to upgrade with confidence.\nFurthermore, game software compatibility is also a major challenge. Whether current Switch titles can be played on the successor is an important factor for many fans. How Nintendo will address these expectations and challenges is something to watch.\nSwitch Successor Release Period and Compatible Software Attention-grabbing information is gathering about the Switch successor\u0026rsquo;s release period and compatible software. The release date of this highly anticipated new model and what software will be compatible are very important points. Let\u0026rsquo;s build up your expectations based on the latest information.\nRegarding the release period, we await an official announcement from Nintendo, but rumors point to early 2024 as likely. Considering Nintendo\u0026rsquo;s past product release patterns, spring could be a target window. With new features and performance improvements expected, fan interest is high.\nSpecifically, whether current Nintendo Switch software can be played on the successor is a key concern for many users. Since Nintendo has prioritized compatibility in the past, it\u0026rsquo;s highly likely that current software will work as-is. This would make the transition to the new model smooth for Switch users.\nWhen is the Release Date? Predictions and Rumors Various predictions and rumors are circulating about the release date of the next-generation Nintendo Switch successor. In particular, a 2024 release is considered likely, and an official announcement from Nintendo is awaited. According to recent reports, development is progressing smoothly, but specific dates remain undetermined.\nMany industry analysts expect an announcement at a 2024 trade show. Considering Nintendo\u0026rsquo;s past release patterns, a spring to summer release is also considered highly possible. Furthermore, the performance improvements of the next-generation console may also affect the release date.\nUsers are also questioning whether current Switch software can be played on the successor. Official information on this point is also awaited. As attention focuses on Nintendo\u0026rsquo;s movements, fans are building their expectations.\nCan Current Switch Software Be Played? Current Nintendo Switch software is expected to be essentially playable on the successor. Nintendo has prioritized hardware compatibility in the past. For example, since Wii U software could be played on the Switch, a similar approach may be taken with the successor.\nAdditionally, current Switch software continues to receive updates and additional content through online services. This allows users to enjoy existing games on new hardware.

In particular, since graphics and performance improvements are expected, not all current software is guaranteed to work, but the majority of titles should be playable without issues.\nDesign and Performance Evolution Design and performance evolution are particularly noteworthy points for the Nintendo Switch successor. With the arrival of new hardware, the gaming experience could change significantly. More beautiful graphics and comfortable controls are expected, making it attractive for gamers.\nThe reason for this evolution is technological advancement and changing user needs. The gaming industry is constantly evolving, and players demand higher quality experiences. To meet this, Nintendo needs to revamp the design and performance of the next-generation console. In particular, performance improvements in both portable and docked modes are required.\nFor example, while the current Switch has limitations in resolution and frame rate, the successor is expected to ease these constraints. Support for 4K resolution would enable more realistic visual expression. This is expected to further deepen game immersion. We\u0026rsquo;ll explain the next evolution in detail below.\nSwitch Successor Design Predictions Predictions about the Switch successor\u0026rsquo;s design are receiving significant attention among gamers and fans.

Combining these elements, the Switch successor is expected to play a role not just as a gaming console but as part of a lifestyle. What innovations Nintendo will bring is eagerly awaited.\nGraphics Performance Improvement Points Graphics performance improvement is an important point for the Nintendo Switch successor. While the current Switch has different performance levels between portable and TV modes, with limitations on graphics quality, the next-generation console is expected to significantly enhance the visual gaming experience through higher resolution displays and the latest GPU technology.\nFor example, more titles supporting 4K resolution would enable more realistic graphics. The introduction of ray tracing technology would make light reflections and shadow expressions more natural, increasing game immersion. Players can expect new gaming experiences.\nFor developers, enhanced graphics performance also expands creative expression possibilities. This increases the likelihood of more diverse game genres appearing. How these technological advancements will be realized on the next-generation console is very exciting.\nPrice and Purchase Timing Considerations Many gamers are interested in the Switch successor\u0026rsquo;s price and purchase timing. With the arrival of new hardware, it\u0026rsquo;s important to consider what pricing to expect and when to buy.\nRegarding the expected price, considering that the current Nintendo Switch sells for around 30,000 yen, the successor will likely be in the 40,000 to 50,000 yen range. This price point seems reasonable considering performance improvements and new features.\nPurchase timing also requires consideration. Right after a new model launches, demand is high and prices often fluctuate. Initial batches are expected to be scarce, so waiting a few months after release may stabilize inventory and prices. Keeping these points in mind, it\u0026rsquo;s important to plan your purchase.\nExpected Price and Reasons The expected price for Nintendo\u0026rsquo;s Switch successor is estimated to be around 45,000 to 50,000 yen. This pricing is influenced by rising raw material costs and the introduction of new technology. In particular, the next-generation console will likely feature high-performance processors and graphics chips, which will increase manufacturing costs. Considering competitors\u0026rsquo; price ranges, many agree this range is appropriate.\nFurthermore, Nintendo has historically emphasized the balance between price and performance. Therefore, even if the initial retail price is high, options to increase long-term user satisfaction are expected to be provided. As game quality improves, more users will consider purchasing. The expected price depends on various factors, so future developments are worth watching.\nBest Timing for Upgrade Determining the right timing for an upgrade is very important when purchasing a gaming console. With the Nintendo Switch successor expected to arrive, many users are considering switching from the current model. When a new model launches, the old model\u0026rsquo;s price typically drops. Therefore, as the successor\u0026rsquo;s release approaches, more people may hesitate to buy the current Switch.\nThe best timing for an upgrade is also influenced by game lineups and exclusive title announcements.

Furthermore, taking advantage of sales and campaigns can help you get a new model at a better price.\nBy keeping an eye on the Switch successor\u0026rsquo;s release schedule and game trends, it\u0026rsquo;s important to determine the right timing for a smart upgrade.\nFrequently Asked Questions About the Nintendo Switch Successor Frequently asked questions about Nintendo\u0026rsquo;s Switch successor are a topic of high interest for many fans. In particular, how the successor differs from the current Switch and what will happen to the current Switch after release are key points.\nThe successor is expected to significantly improve performance and features.

Today, we are diving deep into the Wi-Fi router — an essential device for modern life. With smartphones, computers, game consoles, and even home appliances connecting to the internet, a good Wi-Fi environment is crucial. This guide covers how to choose the right router and get the most out of it.\n1. Understanding Wi-Fi Router Basics What Does a Wi-Fi Router Do? A Wi-Fi router wirelessly delivers internet to devices throughout your home or office. Think of your internet connection as a highway; the router acts as the intersections and off-ramps that distribute traffic throughout your house. Choosing the right router reduces congestion and enables smooth communication.\nKey Specs and Standards Wi-Fi Standard (802.11n/ac/ax): The latest Wi-Fi 6 (802.11ax) offers high speed and stability, maintaining performance even with many connected devices. Dual-Band vs. Tri-Band: Most routers use 2.4GHz and 5GHz bands. Dual-band supports both; tri-band adds another band for even better performance. Speed Ratings: Numbers like \u0026ldquo;1200Mbps\u0026rdquo; or \u0026ldquo;2400Mbps\u0026rdquo; are theoretical maximums. Actual speed depends on your environment and devices. 2. How to Choose the Right Router Consider User Count and Connected Devices Match the router to your household size. A single person may be fine with an entry model, but families streaming video and gaming need higher-performance models.\nCheck Coverage Area Wi-Fi signals struggle in large homes or reinforced concrete buildings. Consider these solutions:\nHigh-power routers: Stronger signal output. Wi-Fi extenders: Boost coverage in weak spots. Mesh Wi-Fi: Multiple units working together for whole-home coverage. 3. Tips for Effective Router Use Placement Matters Place the router in a central, open location for best signal distribution. Avoid:\nHiding behind walls or furniture Placing near electronic devices (microwaves, etc.) Set a Strong Password Change from the default password. Use a long, complex combination of letters, numbers, and symbols.\nRegular Updates Router firmware updates improve security and performance. Check the manufacturer\u0026rsquo;s website periodically.\n4. Recommended Wi-Fi Routers Beginner-friendly: TP-Link Archer A7 — Great value with essential features. High-speed: ASUS RT-AX88U — Wi-Fi 6, high performance, great for gamers. Mesh: Google Nest Wifi — Easy setup, covers the whole home. Choose the right router and enjoy a fast, reliable internet connection.

Even if you are not familiar with technology, this article will explain basic internet terms in a simple, easy-to-understand way.\nThe Basic Structure of the Internet The internet is a vast network of computers connected worldwide, exchanging information. More specifically, it is made up of many smaller networks (like home or office networks) connected together. When these networks communicate, they use communication rules called protocols. Thanks to these protocols, we can access websites, stream videos, and send emails.\nWhat Is an IP Address? An IP address is like a \u0026ldquo;postal address\u0026rdquo; on the internet — it identifies a specific computer or device. Just as you need an address to send mail, the internet needs an address to send information to the right destination.\nThere are two types of IP addresses: IPv4 and IPv6. IPv4 has been used for decades and is still common, but IPv6 is a newer format designed to support the growing number of connected devices.\nDomain Names and DNS A domain name is the name of a website (e.g., netguide.jp). But computers communicate using IP addresses, not names. Remembering IP addresses for every site would be impossible. That is where DNS (Domain Name System) comes in. DNS automatically converts domain names into their corresponding IP addresses, so you can access websites without typing numbers.\nHTTP vs HTTPS HTTP (HyperText Transfer Protocol) and HTTPS (HTTP Secure) are communication protocols used to access websites.\nHTTP is the standard protocol for transferring data on the web. HTTPS adds a security layer to HTTP, encrypting data in transit. When handling sensitive information like credit card numbers or passwords, HTTPS should always be used to prevent eavesdropping. That wraps up this beginner\u0026rsquo;s guide to the basic structure of the internet! Learning these fundamental terms will make the world of IT much more approachable.

DNS (Domain Name System) plays a crucial role when you access websites. This article explains the basics of DNS, how to choose faster DNS servers, and the specific setup steps.\nWhat Is DNS? DNS (Domain Name System) is like an address book for the internet.

Things to Do When Bored and Alternative Ways to Play"},{"content":"Sharing my experience of falling for a task scam, in the hope that it helps others avoid the same fate. What seemed like a simple, safe task ended up causing significant financial damage. Here is the full story in detail.\nThe Scam Method The scam I encountered was deceptively simple: send screenshots of YouTube videos for payment. The scammers explained that completing this task would earn a reward. It required no special skills or significant time, so I participated without suspicion. But this was just the beginning of the trap.\nThe Damage This scam cost me a total of 200,000 yen. The scammers, pretending to process reward payments, demanded various fees and deposits under different pretexts. The amounts started small, so I paid without suspicion, but the demands escalated until I had paid a substantial sum before realizing what was happening.\nHow the Scammers Operated The scammers used multiple bank accounts — a common technique to avoid detection. By receiving small transfers to different accounts, they make it difficult to track the fraud.\nThe Specific Scheme One day, I received an SMS message: \u0026ldquo;Want an easy part-time job?\u0026rdquo;\nI was short on money, and curiosity got the better of me — I added them on LINE.\nThe scammers immediately sent details: \u0026ldquo;Just send screenshots of specified YouTube videos and earn 50,000 yen per day.\u0026rdquo; Even though I suspected it was a scam, curiosity made me go along.\nDespite my doubts, I watched the specified videos and sent screenshots. To my surprise, 150 yen was actually deposited.\nEncouraged by this, I followed the scammers\u0026rsquo; instructions: \u0026ldquo;To withdraw more money, you need to register on our dedicated site\u0026rdquo; and \u0026ldquo;From now on, we communicate via this dedicated chat app.\u0026rdquo;\nOn the dedicated chat app, I kept completing tasks, earning 7,000 yen for less than an hour of work per day.\nThen came the invitation: \u0026ldquo;Want to try a high-reward task?\u0026rdquo;\nThe scheme: deposit money into a specified account, perform operations on their site, and the money would increase by 1.3x.\nI knew this was the real scam, but I sent 3,000 yen anyway. After performing the specified operations, the money really did increase to 1.3x.\nExcited, I sent 10,000 yen for the next high-reward task. But the scammers claimed the money was lost due to an \u0026ldquo;operation error.\u0026rdquo;\nRegretting my mistake, I sent another 10,000 yen. This time it succeeded, and 10,000 became 13,000.\nWhen I tried to withdraw, they said: \u0026ldquo;This task requires 3 rounds.\u0026rdquo; They demanded an additional 30,000 yen deposit, which I paid in complete trust.\nAfter performing the operations again, they claimed: \u0026ldquo;There was an error in your operation — you need to pay 150,000 yen.\u0026rdquo; I convinced myself that my money would increase and I would get everything back, so I sent the 150,000 yen. It too \u0026ldquo;increased\u0026rdquo; to 1.3x.\nWhen I finally tried to withdraw, they demanded another 300,000 yen. That is when I finally realized I had been completely manipulated.\nThe lesson: no matter how simple or safe a task seems, be extremely cautious when strangers on the internet demand money.\nMy Regrets Acting out of curiosity even though I knew it was a scam Not thinking calmly when asked to transfer large amounts Having internet banking enabled, making it too easy to send money Lack of knowledge about fraud prevention What to Do If You Are Scammed If you fall victim to a scam like this, contact the police or a consumer center immediately. Share the bank account information used by the scammers.\nThe police have a dedicated cybercrime reporting hotline: https://www.npa.go.jp/bureau/cyber/soudan.html (Japanese)\nFor wire transfer fraud, contact your bank. In my case, I contacted PayPay Bank\u0026rsquo;s \u0026ldquo;Wire Fraud Consultation\u0026rdquo; service. This can trigger the \u0026ldquo;Wire Fraud Relief Law\u0026rdquo; to freeze the scammer\u0026rsquo;s account. However, if the account is empty, recovery is impossible — act quickly before the scammers drain the account.\nPrevention Tips Verify: Research the task provider\u0026rsquo;s credibility and avoid anything suspicious. Double-check: Thoroughly review payment conditions and work details. Share information: Warn others on social media and community platforms. Ultimately, online safety requires not just individual vigilance but community-wide information sharing and support. Learn from this incident and stay careful online.\n","date":"2024-05-12T14:00:00Z","image":"/img/thumbnail/scam-task-en.png","permalink":"/en/life/scam-task/","title":"I Fell for the Recent Task Scam — Here Is What Happened"},{"content":"Hello! The world of Minecraft you\u0026rsquo;re about to explore is brimming with infinite possibilities that spark creativity and curiosity. This game offers several modes that players can freely choose, each providing a completely different experience. In this guide, we\u0026rsquo;ll break down the basic progression of Minecraft and its various modes, especially for new players.\nSurvival Mode: The Absolute Basics When starting Minecraft, most players first choose \u0026ldquo;Survival Mode.\u0026rdquo; This mode is literally about survival — players need to secure food, protect themselves from monsters, gather resources, craft tools, and build their own world.\n1. First Steps At the start of your adventure, punch a nearby tree to get wood. Wood is the most basic resource in Minecraft and essential for crafting tools and building materials. Once you\u0026rsquo;ve gathered wood, create a crafting table to make more advanced tools and items.\nIf you turned on the \u0026ldquo;Bonus Chest\u0026rdquo; option (as mentioned in a previous article), a chest packed with useful items and tools will spawn to help you on your journey.\n2. Building a Shelter When night falls in Minecraft, monsters appear. Building a shelter is crucial for surviving your first night safely. A simple dirt house will do, or you can dig into a hillside for a cave shelter. The key is having a place to protect yourself from the night and monsters.\n3. Securing Food Hunger also threatens players in Survival Mode. Hunting wild animals or farming is essential for securing food. Having a stable food source enables long-term survival.\nCreative Mode: Infinite Creativity In \u0026ldquo;Creative Mode,\u0026rdquo; players can build and create to their heart\u0026rsquo;s content without worrying about resources. You can fly and take no damage from monsters. This mode is ideal for building massive castles, creating complex machinery, or simply making art.\nAdventure Mode: Story and Exploration Adventure Mode is designed for enjoying custom maps made by the Minecraft community. In this mode, block placement and destruction are restricted, requiring you to follow the rules and story set by the map\u0026rsquo;s creator. It\u0026rsquo;s perfect for players who enjoy puzzles and exploration.\nHardcore Mode: Ultimate Survival Hardcore Mode cranks up the difficulty of Survival Mode. Here, if you die once, you can never return to that world. The difficulty is locked to the highest level, with increased monster damage and stricter food and resource management. Hardcore Mode awaits challengers who want to test their true survival skills.\nMultiplayer Mode: The Joy of Adventuring Together One of Minecraft\u0026rsquo;s great features is Multiplayer Mode, allowing you to play with friends, family, and players worldwide. You can start your own server or join someone else\u0026rsquo;s, collaborating on large projects or competing for fun. Creating and exploring together makes the Minecraft experience even richer.\nTips for Enjoying Minecraft Don\u0026rsquo;t Fear Exploration: The Minecraft world is vast. Exploring new areas lets you discover unknown resources and interesting terrain. Be Creative: Building your own structures makes the Minecraft world more personal. Look at other players\u0026rsquo; creations for inspiration and try making your own. Join the Community: The Minecraft community is very active. Engage on forums and social media, share ideas, and gain new inspiration. The world of Minecraft can be enjoyed in many different ways depending on the player. Survival Mode requires ingenuity and strategy to survive in nature, while Creative Mode lets players unleash their creativity without limits. With its infinite possibilities, Minecraft constantly offers new challenges and discoveries. From Survival to Creative, Adventure to Hardcore, find the mode that suits you and freely explore this vast world.\nEach mode is just one facet of Minecraft\u0026rsquo;s appeal, but I hope this article helps you on your Minecraft adventure. Most importantly, enjoy your Minecraft journey to the fullest. So, why not start weaving your own story in this vast world?\n","date":"2024-04-01T08:00:00Z","image":"/img/thumbnail/minecraft-flow-en.png","permalink":"/en/game/minecraft-flow/","title":"For Beginners!

Blending creature collection, open-world survival, third-person shooting, and base-building automation, the game has been described as \u0026ldquo;Pokémon with guns\u0026rdquo; — though it goes far deeper than that label suggests. Set across sprawling islands inhabited by over 100 species of Pals, players must gather resources, build bases, craft weapons, and fight alongside their captured creatures against hostile factions and towering boss Pals.\nThe Pal Capture System Capturing Pals is the foundation of everything in Palworld. Each Pal has a type (Element), a set of Work Suitability skills, and Partner Skills. To capture a Pal, reduce its HP and throw a Pal Sphere. Success rate depends on remaining HP, status effects, and sphere quality.\nSphere Type Effective Range Crafting Materials Pal Sphere Early-game, low HP only Paldium Fragment x3, Wood x5 Mega Sphere Mid-game Paldium Fragment x5, Ingot x3 Giga Sphere Late-game Paldium Fragment x10, Refined Ingot x5 Ultra Sphere Endgame bosses Paldium Fragment x20, Carbon Fiber x10 Apply status effects like Sleep or Freeze to dramatically increase capture rate. Shiny (Alpha) Pals glow and are larger — they drop rare items and have better stats, but are harder to catch.\nBase Building and Automation Your base is your lifeline. Choose a flat area near water and ore deposits. The Palbox is the core structure — upgrading it increases your base level, which expands build limits and unlocks new facilities.\nEssential workstations to build early:\nPrimitive Workbench → unlocks basic tools and spheres Stone Furnace → smelts ore into ingots Feed Box → keeps Pals fed automatically Pal Bed → restores Pal sanity overnight Hot Spring → restores Pal sanity actively Assembly Line → mass-produces items (mid-game) Pals assigned to your base automatically perform tasks based on their Work Suitability. For example:\nLamball (Kindling Lv1, Transporting Lv1) — hauls items, lights furnaces Penking (Watering Lv2, Cooling Lv2, Handiwork Lv2) — waters crops and crafts Anubis (Handiwork Lv3, Transporting Lv3, Mining Lv2) — endgame crafting powerhouse Efficiency tip: breed Pals with Artisan or Work Slave passives to double work speed.\nWeapon Crafting and Combat The technology tree unlocks weapons as you gain Technology Points from leveling up. Weapon progression follows a clear path:\nMelee — Club → Bat → Sword → Legendary Sword Ranged — Makeshift Handgun → Handgun → Assault Rifle → Rocket Launcher Palls (weapons) — Some Pals can be used as living weapons (e.g., Foxparks fires continuous flames from your arms) Ammo is crafted at the Weapon Workbench using ore and gunpowder (Charcoal + Sulfur). Stockpile sulfur early — it is a bottleneck resource.\nBoss fights require preparation. Tower Bosses are humanoid commanders with Pals; Field Bosses are giant Alpha Pals roaming the world. Always bring:\n200+ rounds of ammo per boss phase 10+ cooked meals for HP recovery Pals with type advantage (e.g., Water vs Fire) A flying Pal mount for mobility Breeding and Genetics Breeding unlocks some of the strongest Pals. Build a Breeding Farm, assign a male and female Pal, and place a Cake in the box. After a timer, an egg spawns.\nKey breeding rules:\nOffspring species is determined by the parents\u0026rsquo; combination (use online calculators for specific results) Passive skills have a 55% chance to inherit from either parent, 10% chance for random mutation Size and element do not directly inherit Eggs come in three sizes: Small (10 min), Medium (20 min), Large (40 min) incubation Incubation requires a campfire or heater for hot climates; coolers for cold climates. Maintaining temperature is key to hatching rare Pals.\nDungeons and Endgame Content Underground dungeons appear across the map. Each contains procedurally generated rooms, treasure chests, and a guaranteed boss Pal at the end. Dungeons are the only source of Ancient Civilization Parts — required for creating the high-end gear: Pal Metal Armor, Hyper Spheres, and the Legendary Schematic weapons.\nLate-game players should target the Wildlife Sanctuary islands (accessible via flying mount or jet ski). These islands contain rare Pals and high-tier loot, but are guarded by relentless military forces.\nSurvival Mechanics Keep an eye on three meters:\nHunger — depletes over time; eat raw berries early, cooked meals later Sanity — drops when Pals work continuously; build hot springs and beds Stamina — governs sprinting, climbing, gliding, and dodge rolls Death drops all items on the ground. Build a storage chest at base and deposit valuables regularly. Carry a grappling hook for emergency escapes.\nConclusion Palworld succeeds because it takes familiar survival-crafting loops and injects them with creature-collection charm. The automation layer — having Pals run entire production lines — sets it apart from rivals. With regular content updates, a planned PvP mode, and a massive modding community, Palworld has cemented itself as a defining title of the survival genre. Whether you build a factory empire or explore every corner of the map with your trusted Pal team, the world is yours to conquer.\n","date":"2024-02-20T00:00:00+09:00","image":"/img/thumbnail/palworld-en.png","permalink":"/en/game/palworld/","title":"Palworld: The Pokémon-with-Guns Survival Game Guide"},{"content":"Hello!
