Introducing GlintCode ✨ I've been building GlintCode , a lightweight scripting language for the browser that runs on top of JavaScript. The goal is simple: make building browser apps easier with a clean, beginner-friendly API while still using the power of JavaScript under the hood. Features 🚀 Runs directly in the browser 📝 Uses <script type="glint"> 🌐 Built-in DOM helpers 🎨 Simple UI creation functions 🔁 Built-in loop helpers 📦 Optional module system ⚡ No build tools or compilation required Hello, World <script src= "https://fast4word.github.io/glintcode/glint.js" ></script> <script type= "glint" > page ( " Hello " ) heading ( " Welcome to GlintCode " , 1 ) paragraph ( " Your first Glint app! " ) button ( " Click Me " , () => { print ( " Hello from Glint! " ) }) </script> Why GlintCode? JavaScript is incredibly powerful, but for beginners or small browser projects it can sometimes feel more verbose than necessary. GlintCode provides a set of simple, readable functions that make creating interfaces and interacting with the page easier, while still letting you use JavaScript features whenever you need them. Because GlintCode runs on top of JavaScript, you can gradually learn the underlying language without giving up access to the browser's APIs. What's next? I'm continuing to expand GlintCode with new functions, modules, examples, and documentation. Future plans include additional built-in libraries, a richer module ecosystem, and more developer tools. I'd love to hear your feedback, suggestions, or ideas for features you'd like to see! GitHub: https://github.com/Fast4word/glintcode

Stop memorizing ANSI escape sequences. I built a browser tool to generate them visually — pick colors, styles, and get the code ready to paste. Try it 🔗 ANSI Color Code Generator — DevNestio Features 3 color modes : 8-color, 256-color palette, RGB truecolor (24-bit) 8 text styles : Bold, Dim, Italic, Underline, Blink, Reverse, Hidden, Strikethrough Separate FG/BG : Set foreground and background colors independently 3 output formats : Shell ( echo -e ), Python ( print ), Raw escape sequence Live preview in a simulated terminal box How ANSI sequences work ESC [ <codes> m Multiple codes are separated by ; . Reset is ESC[0m . 8-color : codes 30-37 (FG), 40-47 (BG), 90-97 (bright FG) 256-color : ESC[38;5;<0-255>m for FG, ESC[48;5;<0-255>m for BG RGB truecolor : ESC[38;2;<R>;<G>;<B>m 256-color palette calculation function get256Color ( i ) { if ( i < 16 ) return standardColors [ i ]. hex ; if ( i < 232 ) { const n = i - 16 ; const r = Math . floor ( n / 36 ) * 51 ; // 255/5 = 51 const g = Math . floor (( n % 36 ) / 6 ) * 51 ; const b = ( n % 6 ) * 51 ; return `rgb( ${ r } , ${ g } , ${ b } )` ; } const v = ( i - 232 ) * 10 + 8 ; // 24 grayscale steps return `rgb( ${ v } , ${ v } , ${ v } )` ; } Output examples # Bold red text on black echo -e " \e [1;31mHello, Terminal! \e [0m" # RGB orange (Python) print ( " \0 33[38;2;255;128;0mOrange text \0 33[0m" ) Tested with 128 assertions covering code generation, color math, and format strings.

I built a browser-based bitwise calculator that performs AND, OR, XOR, NOT, NAND, NOR, XNOR, arithmetic/logical shifts, and rotate operations on 32-bit integers — with a live clickable bit grid. Try it 🔗 Bitwise Calculator — DevNestio Features 13 operations : AND, OR, XOR, NOT A/B, NAND, NOR, XNOR, SHL, SHR, SHRA, ROTL, ROTR Visual 32-bit grid : Click any bit to toggle Operand A on the fly Multi-base input : Auto-detect 0xFF , 0b1010 , 0o17 , or decimal 4 output formats : Hex, decimal, binary (grouped), octal — all with copy buttons No server, no upload — everything runs in-browser The JavaScript integer trap Bitwise ops in JS coerce values to signed 32-bit integers. To get unsigned results you need >>> 0 : case NOT_A : return ( ~ a ) >>> 0 ; // without >>> 0, ~0 shows as -1 case XNOR : return ( ~ ( a ^ b )) >>> 0 ; case ROTL : return (( a << s ) | ( a >>> ( 32 - s ))) >>> 0 ; Rotate without a dedicated instruction JavaScript has no ROL/ROR, so combine two shifts: // Rotate left by s bits (( a << s ) | ( a >>> ( 32 - s ))) >>> 0 Tested with 99 assertions All core logic — parsing, computing, edge cases like XNOR with ~0xFF = 0xFFFFFF00 — covered in a Node.js test file using assert .

Almost every time I'm working out of a coffee shop, and sometimes at the airport, someone spots the stand my laptop is sitting on and asks, "What is that? Where'd you get it?" It happens enough that I figured I'd just write down what I actually travel with, for conferences or any time I'm not working out of my home office. Some links in this post are affiliate or referral links, which means I may earn a small commission or credit at no additional cost to you. My work travel gear list Roost Laptop Stand . This is the one that starts the conversation. It folds down into something small enough to slide into a bag pocket, and it raises my laptop screen to a much more comfortable height, so I'm not hunched over it all day. Apple Magic Trackpad (White) . I used to use this at my desk too, but work gave me an MX Master 3, and I've since moved on to the MX Master 4. The Magic Trackpad is strictly a travel tool these days. A tiny, folding Bluetooth keyboard. I bought a Jelly Comb Ultra Slim Folding Bluetooth Keyboard years ago and I don't think that exact model is even sold anymore, but the category is the takeaway here: a folding keyboard that fits in a jacket pocket is genuinely great to have on hand. An Anker 25,000mAh laptop power bank with three USB-C ports capable of delivering up to 100W. This one's big enough to actually charge my MacBook when I'm away from an outlet, rather than just topping up my phone. An Anker 727 Charging Station . This is basically my travel power hub: two USB-C ports, two USB-A ports, two AC outlets, and a detachable five-foot extension cord, all in something about the size of a phone. It can charge up to six devices at once and delivers up to 100W, so when I have access to an outlet, I use it for my MacBook, phone, watch, AirPods, and anything else that needs power. I leave the regular Mac power brick at home and bring this, the power bank, and my MagSafe cable instead. It looks like this exact model is currently unavailable, but it's worth s

I once spent forty minutes at eleven at night debugging a deploy that wasn't broken. The release script ran the database migration, the migration threw connection refused , the script exited non-zero, the deploy rolled itself back, and I got paged. So I did the things you do. I read the migration. I read the logs. I checked the database — it was up, it was healthy, it accepted my connection instantly. I re-ran the deploy and it worked. I chalked it up to gremlins and went to bed, which is the part I'm not proud of, because it happened again two days later. That time I watched the timing: the script brought up a fresh database container and started the migration about six seconds before Postgres finished initializing and began accepting connections. The migration was racing the database's boot. Most of the time it won. The times it lost, I lost forty minutes. The script wasn't wrong about anything except one assumption: that a dependency is ready the instant you ask for it. In production, dependencies are eventually ready That's the mental model shift. Networks blip. A service you call returns a 503 for the two seconds it takes to finish a rolling restart. An API rate-limits you with a 429 it fully expects you to retry. A fresh container's database isn't accepting connections for its first few seconds. Treating the first failure as fatal turns every one of these normal, transient conditions into a paged engineer — and the script that handles them isn't smarter — it declines to give up on the first try. But retrying naively is its own trap. Retry instantly and you hammer a recovering service into staying down. Retry forever and a genuinely dead dependency hangs your script indefinitely. Retry a 404 and you wait a minute to confirm what you already knew. Good retries are bounded, backed off, and selective. A retry function you can reuse anywhere #!/bin/bash # Purpose: survive transient failures instead of dying on the first error set -euo pipefail CHECK = "✓" CROSS = "

I built GameDeck — a gaming platform where you pick a badge, type a name, and play. That's it. No accounts, no launcher downloads, no tracking. Here's how I built it and what I learned. The stack Frontend : Pure browser-based, vanilla JS Deployment : Google Cloud Run i18n : 3 languages (EN, 简体中文, 繁體中文) with instant switching Identity : Emoji badge system — no usernames, no passwords The architecture The entire app is a single-page browser app. No backend for user auth (because there is no auth). Sessions are ephemeral — nothing is stored. Multi-language i18n Adding 3 languages was the #1 feature request within 24 hours of launch. Simple key-value translation maps, no framework needed. The badge identity system Instead of usernames, users pick an emoji badge (🎮 ⚡ 🦊 🐉 🐼 🚀 🐱 🐯 🌟 🍿). This turned out to be the most talked-about feature. It's fun, zero-friction, and surprisingly expressive. Privacy by default No data collected. No cookies. No analytics. Just the game. Privacy isn't a feature — it's the absence of features that invade privacy. What I'd do differently Multi-language from day 1 More game variety before launch Better mobile responsiveness Try it : https://gamedeck-804028808308.us-west2.run.app Source : Built solo, open to questions! Would love feedback from the dev community — especially on the browser game architecture and i18n approach.

عندما توقف Claude Fable 5 عن العمل في 12 يونيو 2026 بموجب ضوابط التصدير الأمريكية، فعل فريقك ما فعلته أغلب الفرق: أعاد توجيه الإنتاج إلى Claude Opus 4.8 أو Sonnet 4.6، أصلح الأوامر المعطلة، وتجاوز الانقطاع. رُفعت الضوابط في 30 يونيو، وعاد Fable 5 للعمل اعتبارًا من 1 يوليو عبر Claude.ai ، وواجهة برمجة التطبيقات API، وClaude Code، وCowork. أكدت Anthropic إعادة النشر الكامل في إعلانها الرسمي . جرّب Apidog اليوم الخطوة السهلة هي التراجع عن آخر تغيير في التكوين واعتبار المشكلة منتهية. لا تفعل ذلك. الخدمة التي تعود إليها ليست بالضرورة مطابقة سلوكيًا لما استخدمته قبل الانقطاع: أُعيد تدريب طبقة الأمان، وقد تختلف جاهزية المنصات السحابية حسب المنطقة، وأصبح Opus 4.8 الذي استخدمته لثلاثة أسابيع خط الأساس العملي للمقارنة. تعامل مع العودة إلى Fable 5 كترحيل إنتاجي: تحقق، اختبر، قارن، ثم اطرح تدريجيًا. جرد ما تغير أثناء غيابك بين 12 يونيو و1 يوليو، تغيرت ثلاثة أشياء. وشيء واحد بقي كما هو. 1. أُعيد تدريب مصنف الأمان يأتي Fable 5 المعاد نشره مع مصنف أمان أُعيد تدريبه لاستهداف تقنية كسر حماية أُبلغ عنها أثناء الانقطاع. تقول Anthropic إنه يحظر أكثر من 99% من محاولات استخدام هذه التقنية. النقطة المهمة للتطبيقات الإنتاجية: الطلبات المصنفة لا تفشل بالضرورة. تُعاد توجيهها تلقائيًا إلى Claude Opus 4.8. الرد يحمل إشعارًا بذلك. أكثر من 95% من الجلسات لا ترى أي تراجع. هذا يعني أن أوامرك تعمل الآن أمام طبقة أمان مختلفة قليلًا. لا تفترض أن نتائج أوائل يونيو ما زالت صالحة؛ أعد الاختبار. 2. تحقق من حالة المنصة السحابية أعاد Amazon Bedrock دعم Fable 5 في 1 يوليو، في نفس يوم واجهة برمجة التطبيقات الأساسية، لكن ملفات تعريف الاستنتاج الإقليمية قد تُطرح بشكل غير متساوٍ. قد يكون Google Vertex AI وMicrosoft Foundry ما زالا في مرحلة اللحاق. توجيه Anthropic للمنصات المعلقة هو "بأسرع وقت ممكن"، بدون تاريخ محدد. إذا كنت تستخدم موفرًا سحابيًا، لا تغيّر الإنتاج قبل التحقق من: توفر Fable 5 على المنصة. توفره في المنطقة التي تستخدمها. توافق اسم النموذج أو ملف تعريف الاستنتاج مع تكوينك الحالي. 3. خطط الاشتراك لها تاريخ يجب مراقبته إذا كان أعضاء الفريق يستخدمون Claude عبر خطط الاشتراك بدلًا من مفاتيح API، فهناك تغ

Your portfolio is often the first impression a recruiter, client, or fellow developer gets of you. If it loads slowly, ranks nowhere on Google, or is a pain to update, it's working against you instead of for you. Here's how I approached optimizing mine — covering performance, SEO, and everyday usability. 1. Start With a Lightweight Foundation The biggest performance wins come before you write a single line of custom code. Pick a lean stack. Static site generators (Astro, Next.js with static export, Hugo, or even plain HTML/CSS/JS) ship far less JavaScript than a full SPA framework for a mostly-static portfolio. Avoid unnecessary UI libraries. A heavy component library for a five-page site adds kilobytes you don't need. Hand-roll simple components instead. Use system fonts or self-host web fonts. Pulling fonts from a third-party CDN adds an extra DNS lookup and render-blocking request. Self-hosting with font-display: swap avoids layout shift and speeds up first paint. 2. Optimize Images (This Is Usually the Biggest Win) Images are almost always the heaviest assets on a portfolio site. Convert images to WebP or AVIF — typically 30–50% smaller than JPEG/PNG at the same visual quality. Resize before upload. Don't serve a 4000px-wide photo in a 600px container. Use loading="lazy" on below-the-fold images so the browser doesn't fetch them until needed. Add explicit width and height attributes to prevent layout shift (this also helps your Cumulative Layout Shift score). <img src= "/project-thumb.webp" alt= "Project screenshot" width= "600" height= "400" loading= "lazy" /> 3. Minimize and Defer JavaScript Ship only the JS a page actually needs — code-split per route if your framework supports it. Defer non-critical scripts (analytics, chat widgets) with defer or load them after the page is interactive. Audit your bundle with a tool like source-map-explorer or your framework's built-in bundle analyzer to catch unexpectedly large dependencies. 4. Nail the SEO Basics Good perf

Every developer has that one project. The passion build that sits in the back of your mind for months—or even years—before you finally sit down, crack your knuckles, and make it a reality. For me, that project was building a modern, open-access bilingual digital lexicon bridging English and Assamese: AssameseDictionary.org . While it started as a personal milestone dream, it quickly turned into a massive data engineering and architecture challenge. Here is how I tackled parsing a massive vocabulary database and serving it globally with near-zero latency. 🏗️ The Core Challenge: Scale vs. Speed A dictionary isn't like a standard SaaS app or landing page. It lives and dies by its database depth. To make this a truly definitive tool, I compiled, cleaned, and programmatically validated an extensive vocabulary index mapping over 293,000 words . The dataset doesn't just hold simple translations; it maps complex bidirectional lookups, phonetic transliterations, advanced English definitions, context usage examples, and cross-linked synonym tokens. If I threw this massive dataset into a traditional relational database hooked up to a standard server setup, I ran into immediate roadblocks: Latency: Heavy search queries on a dataset this size can cause noticeable lag. Cost/Overhead: Maintaining and scaling database servers for unpredictable public traffic gets expensive fast. I wanted the search utility to snap back instantly. To achieve that, I had to ditch traditional server paradigms entirely. ⚡ The Architecture: Serverless Edge Caching To keep things ultra-lightweight, highly cost-effective, and blazing fast, I built the platform around an edge-computing topology: The Runtime: I offloaded the backend logic entirely to Cloudflare Workers . Instead of routing traffic to a centralized origin server, queries are intercepted and executed at serverless edge locations physically closest to the user. The Data Layer: Instead of an active SQL database bottleneck, I mapped the data mat

Introduction: Unveiling the Critical Vulnerability The recently identified CVE-2026-8037 vulnerability in Progress Kemp LoadMaster represents a critical threat to enterprise infrastructure. This remote code execution (RCE) flaw, stemming from an uninitialized heap issue , enables pre-authentication exploitation, allowing attackers to bypass initial security barriers without valid credentials. The root cause lies in the failure to initialize dynamically allocated memory regions, creating an exploitable condition where untrusted input can corrupt critical data structures. Attackers leverage this memory corruption to redirect program execution to malicious payloads, achieving full system compromise—from data exfiltration to operational disruption. Technically, the vulnerability arises during the software’s handling of untrusted input. When memory chunks in the heap are allocated but not properly initialized, they retain residual data or undefined states. Attackers exploit this oversight by crafting inputs that overwrite function pointers or control-flow structures, hijacking the program’s execution path. The causal sequence is precise: uninitialized heap → memory corruption → arbitrary code execution → system compromise. The pre-authentication nature of the exploit exacerbates the risk, as attackers require no prior access to execute their payload, rendering perimeter defenses ineffective. The implications are severe for enterprises relying on Kemp LoadMaster for load balancing and application delivery. Unpatched systems are exposed to infiltration, data theft, and ransomware deployment. Beyond the technical failure, CVE-2026-8037 exposes systemic deficiencies: insufficient input validation in software design and inadequate security testing during development. Organizations further amplify risk through delayed patch management , creating a critical window of opportunity for attackers. Immediate remediation is imperative to prevent catastrophic breaches that could under

Pricing is the single most powerful lever you have for growing SaaS revenue — yet most founders treat it as an afterthought. A 1% price increase can yield an 8-12% increase in operating profit, far more than acquiring the same revenue through new customers. This playbook covers the five core decisions every SaaS company must make: monetization model, value metric, tier structure, psychological pricing tactics, and pricing page optimization. Introduction: Why Pricing Is Your Most Important Growth Lever When founders think about growth, they typically reach for familiar levers: more marketing spend, bigger sales teams, viral features. But pricing is the one lever that touches every single customer interaction — and it costs nothing to change. Consider this: if you raise prices by 1% and lose 1% of customers, your net revenue still increases. The math works because the lost customers are often your least price-sensitive ones. In practice, companies that run pricing experiments typically find they can increase prices by 5-15% before seeing any meaningful impact on conversion. Yet pricing is also where most SaaS companies are at their most irrational. We underprice out of fear, copy competitors without understanding why, and avoid changes because we're afraid of customer backlash. Freemium vs Free Trial vs Paid-First Freemium Freemium offers a permanently free tier with limited features. It's a top-of-funnel machine — but it requires low marginal cost per user and a clear upgrade path. Aspect Freemium Best for Products with viral loops, network effects Conversion rate Typically 2-5% free-to-paid Risk High support cost for free users Example Slack, Notion, Canva Free Trial (Time-Limited) Time-limited trials give full access for 7-30 days, then require payment.

Introduction to Hydration and Rendering Strategies In the relentless pursuit of faster, more responsive web applications, developers have engineered a spectrum of hydration and rendering strategies . Each approach emerges as a response to specific performance bottlenecks, yet none is universally optimal. This section dissects the core mechanics of these strategies, their historical evolution, and the critical problem they aim to solve—balancing speed with practicality. The Problem: A Trade-Off Landscape At its core, the challenge is mechanical : how to deliver content to the user’s browser with minimal latency while maintaining interactivity. Traditional rendering methods (e.g., server-side rendering) prioritize initial load speed but often defer interactivity until JavaScript execution. Client-side rendering, conversely, delays the first paint but ensures seamless interactions post-hydration. The tension between these extremes has birthed hybrid strategies like incremental hydration and islands architecture , each addressing specific failure points in the rendering pipeline. Key Mechanisms Driving Strategy Evolution Advancements in Web Technologies : New APIs (e.g., Web Components, Streaming SSR) enable finer-grained control over rendering. For instance, streaming SSR reduces Time-to-First-Byte (TTFB) by sending HTML in chunks, but risks breaking the causal chain of DOM hydration if not synchronized with client-side scripts. User Expectations : Sub-second load times are no longer aspirational but expected. This pressure deforms traditional workflows, pushing developers toward pre-rendering or static site generation (SSG), which trade dynamic flexibility for speed by offloading rendering to build time. Competitive Pressure : Performance is a zero-sum game. Companies adopt strategies like partial hydration (hydrating only interactive components) to minimize JavaScript payload, but this risks breaking interactivity if the hydration boundary is misaligned with user int

We’ve all been there. You get a notification from your smartwatch saying your heart rate has been a bit funky, or your blood oxygen is dipping. Usually, we ignore it until it becomes a problem.

Loop Engineering — เมื่อการ Prompt Agent ด้วยมือไม่พออีกต่อไป แล้ว Programmer ต้องออกแบบ Loop แทน โดย Nokka (นก-กา) | 1 กรกฎาคม 2026 TL;DR — สำหรับคนที่รีบ กลางเดือนมิถุนายน 2026 ที่ผ่านมา วงการ AI developer สั่นสะเทือนด้วยประโยค 6 คำจาก Peter Steinberger ผู้สร้าง OpenClaw: "You shouldn't be prompting coding agents anymore. You should be designing loops that prompt your agents." ประโยคนี้มียอดวิว 8 ล้านครั้งในวันเดียว และจุดกระแส "Loop Engineering" ที่กลายเป็น buzzword ร้อนที่สุดของเดือน Loop Engineering คือการเปลี่ยนจากการนั่ง Prompt Agent ทีละคำสั่ง มาเป็นการเขียน Loop (โปรแกรม) ที่ทำหน้าที่ Prompt Agent แทนคุณ โดย Loop จะเป็นคนเลือกงานต่อไป, ส่งให้ Agent, ตรวจสอบผล, ตัดสินใจว่าจะทำต่อหรือหยุด คุณไม่ได้เป็นคนขับ Agent อีกต่อไป — คุณเป็นคนออกแบบระบบที่ขับ Agent 1. Loop Engineering คืออะไร? เกิดมาจากไหน? เรื่องนี้เริ่มต้นจาก Boris Cherny ผู้สร้าง Claude Code พูดบนเวที Acquired Unplugged ต้นเดือนมิถุนายน 2026 ว่า: "I don't prompt Claude anymore. I have loops that are running. They're the ones that are prompting Claude and figuring out what to do. My job is to write loops." สองวันต่อมา Peter Steinberger โพสต์บน X ว่า "You shouldn't be prompting coding agents anymore. You should be designing loops that prompt your agents." โพสต์นี้มียอดวิว 8 ล้านครั้ง [1] หลังจากนั้น Addy Osmani (Google Engineer, O'Reilly author) เขียนบทความ "Loop Engineering" บน O'Reilly Radar ให้คำจำกัดความว่า: "Loop engineering is replacing yourself as the person who prompts the agent." [2] และ @0xCodez ก็รวบรวมเป็น 14-step roadmap จาก "prompter" สู่ "loop designer" [3] ในมุมมองของผม Loop Engineering ไม่ใช่ buzzword ธรรมดา แต่มันคือการเปลี่ยน abstraction layer ของการทำงานกับ AI เหมือนกับที่เราเปลี่ยนจาก Assembly → High-level language หรือจาก Bare metal → Cloud แต่ก็ต้องยอมรับว่า Loop Engineering ยังเป็นแนวคิดใหม่ และยังไม่มี standard practice ที่ชัดเจน สิ่งที่ใช้ได้วันนี้อาจเปลี่ยนไปใน 3 เดือน 2. ทำไมต้อง Loop Engineering? ลองนึกภาพการทำงานกับ AI coding agent แบบเดิม: คุณพิมพ์ prompt → รอ → อ่าน dif
