If you've ever built a feature that extracts text from PDFs, an Arabic-speaking user has probably filed this bug: "the words come out in reverse order." Not the letters — the words . Every line reads last-word-first. I spent the better part of a year fixing this class of bugs while building Confileo , a free PDF toolkit with first-class Arabic support. Here's what's actually going on, because almost every explanation online is wrong or incomplete. The four distinct failure modes People say "Arabic breaks" as if it's one bug. It's four: 1. Visual vs logical order (the reversed-words bug) A PDF doesn't store text the way a Word file does — it stores positioned glyph runs : "paint these shapes at these coordinates." For left-to-right scripts, the paint order happens to match the reading order, so naive extraction works by accident. Arabic is right-to-left. Many PDF generators emit the glyph runs in visual order — the order they appear on screen, left to right. A naive extractor concatenates the runs as stored and produces every line word-reversed. The text was never "reversed" in the file; your extractor just assumed paint order == reading order. Fix: reconstruct logical order using glyph positions + the Unicode Bidirectional Algorithm (UAX #9), not the content-stream order. Libraries like PyMuPDF already return text in logical order — a common mistake is "fixing" that output by reversing it again, which is how you get double-reversed text. Rule of thumb: never reverse Arabic yourself. If it looks backwards, your rendering layer lacks bidi support; the data is usually fine. 2. Disconnected letters (the ransom-note bug) Arabic letters are contextual: ع renders differently in initial, medial, final and isolated positions, and letters join. That joining is applied at render time by a shaping engine (HarfBuzz being the standard). If any step of your pipeline round-trips text through a non-shaping renderer — a canvas library, a barebones PDF writer, an image caption filter

Every business that has ever typed a web address into a browser owes a small debt to a company most people have never heard of. On March 15, 1985, a computer maker called Symbolics registered Symbolics.com and, in doing so, became the first ever holder of a .com domain name. More than forty years later that address is still registered and still resolves - making it the oldest .com domain on the internet. Who was Symbolics? Symbolics Inc. was a Massachusetts company that built specialized computers called Lisp machines - workstations designed from the silicon up to run the Lisp programming language, then the darling of artificial intelligence research. These were serious, expensive machines aimed at labs and universities, and the company sat right at the cutting edge of 1980s computing. So it was fitting, if a little accidental, that they were first in line when commercial domains became available. The domain name system itself was brand new. DNS had only been introduced in 1983 to replace the unwieldy HOSTS.TXT file that every machine on the early internet had to keep in sync. The now-familiar top-level domains - .com , .org , .net , .edu , .gov - were defined in 1984. When registration opened, .com was meant for commercial entities, and Symbolics grabbed theirs before anyone else did. A slow start for the web's most valuable real estate What is striking today is how little demand there was. In the whole of 1985, only a handful of .com domains were registered - names like BBN, Think, and a few other technology companies trickled in over the following months. There was no gold rush, because there was no web yet. Tim Berners-Lee would not propose the World Wide Web until 1989, and the first website would not appear until 1991. A domain name in 1985 was a technical convenience for reaching a machine, not a brand or a piece of property. That makes Symbolics.com a kind of time capsule. It was registered before the web, before browsers, before e-commerce, and before anyon

OAuth recovery emails look harmless until you test them the lazy way. A team sends password reset links or recovery codes into one shared mailbox, confirms that something arrived, and marks the job done. From a security view, that test is too weak. It can hide token reuse, wrong-user delivery, or log retention that exposes sensitive account events. For non-production checks, I like using a disposable email address that belongs to one test run. Some teams build that inbox layer themselves, some use tempmailso, but the core principle is the same: isolate the recovery event, inspect it quickly, and delete the evidence you no longer need. That is helpful when Authentication and OAuth changes ship together. Why OAuth recovery emails deserve their own threat model Recovery email tests are not just "did the mail send?" checks. They sit on the edge of account takeover risk, so the message itself matters almost as much as the login flow. A decent threat model for these emails should ask: did the message reach only the intended inbox for this run? does the link or code expire when the product says it does? is the message revealing too much user data in subject lines or previews? can an older token still be used after a new recovery request? do logs or test fixtures keep the recovery secret longer than they should? This is where shared inboxes become dangerous in a subtle way. Even if nobody has bad intent, mixed test data makes it harder to prove which token belonged to which request. The same operational confusion shows up in email change confirmation checks , and it gets worse when the email can restore account access. OWASP recommends testing authentication recovery features with the same care as sign-in and session controls, because weak recovery paths are a common bypass route for stronger primary login defenses: https://cheatsheetseries.owasp.org/cheatsheets/Forgot_Password_Cheat_Sheet.html A safer test flow for recovery links and codes The cleanest pattern is one inbox

This is a reprint from my tips blog. You can find the original article here: [ https://tips.ojapp.app/en/ios-android-pwa-goal-difference-3/ ] Android vs. iPhone: Different Goals for PWAs When people talk about PWAs, the explanation often sounds like this: Android supports PWAs. iPhone does not support PWAs very well. If you only look at the PWA specifications, this explanation is easy to understand. Android Chrome supports manifest.json, Service Worker, installation, notifications, shortcuts, and many other PWA features quite strongly. iPhone Safari, on the other hand, does not behave the same way as Android. But after testing PWAs on both iPhone and Android many times, I started to see the difference in another way. More accurately, Android and iPhone have different goals for PWAs. That is the biggest difference I noticed while testing repeatedly. Android tries to turn web pages into apps Android PWAs are clearly designed in the direction of making web pages feel closer to native apps. The idea is to take a website opened in the browser and move it toward a native-app-like experience. This direction is very strong on Android. That is why many PWA-related features are well supported. manifest.json Service Worker Push notifications Install Prompt Shortcuts theme_color background_color maskable icons display modes orientation Of course, it is not perfect. Manifest cache can be stubborn, multiple PWAs on the same domain can become confusing, and real-device testing can still create plenty of traps. Even so, when you build according to the PWA specification, Android usually responds in a fairly straightforward way. For example, if you set display: fullscreen , the app feels much more full-screen. theme_color is often reflected in the toolbar color. orientation also works quite strongly on Android. In other words, for Android, a PWA is an app made from the Web . iPhone starts from the experience of placing web pages on the home screen iPhone is different. Even before the

My father is a stroke patient. Watching him try to speak clearly again — with patience, repetition, and no small amount of courage — is what pushed me to build Voice Revive. It’s a free web app for stroke survivors and people with aphasia: pick a category, hear a word, say it back, get forgiving feedback. No accounts, no scores, no pressure. I vibecoded most of it with AI tools, but the reason behind it is deeply personal. If it helps even one person feel a little more confident speaking again, it was worth it. Let’s work together: Voice Revive is a personal project, and I’m open to: Collaboration — features, accessibility, reaching more people who need it Sponsorships — to keep the app free and accessible Part-time / freelance web development — I’m comfortable building with: What I work with today: Next.js & TypeScript Node.js (Express) Python (FastAPI) Tailwind CSS What I’ve built with before (freelance): Kotlin & Java for Android Development(previous experience - freelance) ESP32 & C++ for IOT Development Try it: https://voicerevive.online/ Connect with me: https://www.linkedin.com/in/aaron-mercado-163b02369/

I have been turning old code projects into sellable source-code products. The hard part is not changing the cover image. It is not renaming the ZIP. It is deciding whether the project deserves to be sold at all. A lot of old apps are useful to the person who built them. Far fewer are useful to a stranger who has never seen the repo, never heard the backstory, and only wants to know one thing: Will this save me time, or will it become another folder I regret buying? Here is the checklist I now use before treating a source-code project as a starter kit. 1. The buyer must understand the workflow "Full-stack dashboard" is not enough. A buyer should immediately understand the workflow the project helps with. For example: a review and scoring portal; a maintenance and work-order dashboard; an email-template governance tool; a runnable technical code lab. The more generic the product sounds, the harder it is to buy. I now try to answer this in one sentence: This kit helps [specific buyer] start from a working foundation for [specific workflow]. If I cannot fill that sentence honestly, the project is not ready. 2. A stranger must be able to run it "It runs on my machine" is not a product standard. A buyer needs a path from download to working state. That usually means: setup instructions; environment notes; seeded demo data; demo accounts or fixtures; expected local startup behavior; known limitations; a simple smoke-test checklist. The goal is not perfection. The goal is that a competent developer should not have to reverse-engineer the project before deciding whether it is useful. 3. The product needs proof, not adjectives Marketing adjectives are cheap: production-ready; powerful; scalable; enterprise-grade; battle-tested. Most of those words create more risk than trust if they are not backed by evidence. Better proof looks boring: screenshots; a short demo video; a verified release ZIP; install notes; architecture notes; included / not-included boundaries; a changelog;

Bootstrap 5 and Tailwind CSS are the two most popular CSS frameworks in 2026. If you're starting a new project and trying to decide between them, this guide gives you an honest comparison based on real-world usage — not just feature lists. The Core Difference Bootstrap 5 gives you pre-built components. Tailwind CSS gives you utility classes to build your own. That's the fundamental difference and it drives every other comparison. With Bootstrap you get a navbar, modal, card, and dropdown out of the box. With Tailwind you build those yourself using utility classes like flex , px-4 , bg-blue . Neither is wrong. They solve different problems for different teams. When Bootstrap 5 Makes More Sense You Need to Ship Fast Bootstrap's pre-built components mean you spend less time on UI and more time on business logic. For admin dashboards, CRM panels, and internal tools — where UI consistency matters more than pixel-perfect custom design — Bootstrap is the faster choice. Your Team Knows HTML and CSS Bootstrap has a shallow learning curve. Any developer who knows basic HTML and CSS can pick up Bootstrap in a day. Tailwind requires understanding its utility-first philosophy and memorizing class names. You're Building an Admin Dashboard Admin dashboards need data tables, modals, dropdowns, sidebars, and form components — all of which Bootstrap provides out of the box. Building these from scratch with Tailwind takes significantly more time. You Want Predictable Output Bootstrap's components look consistent across browsers and screen sizes without extra configuration. Tailwind output depends heavily on how well your team implements it. When Tailwind CSS Makes More Sense You're Building a Custom Marketing Site If your design is highly custom — unique layouts, non-standard components, pixel-perfect design system — Tailwind gives you more flexibility without fighting Bootstrap's default styles. You Have a Design System Already If your team has a defined design system with specific t

When I published the first article about the Neuron AI Router , I expected questions about routing rules. Which rule to use for structured output, how to write a custom one, how the round robin behaves under load. Some of those questions arrived, but the most frequent one was different, and it wasn't really about routing at all. It was about failure. What happens to my agent when the provider goes down? It is a fair question, and if you are new to building AI applications it deserves a proper answer before we look at any code. Here is the short version. The new fallback strategy in Neuron AI Router lets you define an ordered list of LLM providers for your PHP agent. When an inference call fails with a transient error, such as a rate limit, a timeout, or an overloaded server, the same request is automatically retried on the next provider in the list. The failover is transparent: the agent never knows it happened, and the conversation continues without losing state. The rest of this article explains why this problem exists, why the usual solutions fall short, and how to configure it. Why LLM providers fail in production An LLM provider is an external service you talk to over HTTP. Every time your agent thinks, it is making a network call to a machine you don’t control, operated by a company that is currently serving millions of other requests. These services fail in very ordinary ways. You hit a rate limit because your traffic spiked. The provider returns an “overloaded” error because their traffic spiked. A request times out. A deployment on their side causes a few minutes of elevated error rates. None of this means you did something wrong, and none of it is rare. If you keep an agent in production long enough, you will see all of these. In a classic web application, a failed call to a third party API is usually a corner of the system. You log it, maybe retry it in a queue, and the rest of the page still works. In an agent based application the inference call is not

The Shop on the Corner: How I Learned System Design Without Building Amazon Nephew asks his uncle — 10 years deep into building large-scale systems — to explain "system design," and all the scary jargon that comes with it. Uncle refuses to start with the jargon. Instead: "Forget servers and databases for a minute. Just imagine you're running a small shop." What follows is a thought experiment, built one problem at a time — no cloud bills, no fancy stack, just a counter, a storeroom, and a lot of common sense. Part 1: The Counter — Your First "API" 👦 Nephew: Uncle, everyone at work keeps throwing around terms — load balancer, cache, index, sharding. I nod along, but I don't actually get any of it. 👨‍🦳 Uncle: Then don't start there. Close your eyes for a second and forget servers exist. Suppose — just suppose — you're running a small shop. One counter, one small storeroom at the back. A customer walks up and asks for something. What do you do? 👦 Nephew: I'd walk into the storeroom, find it, walk back, hand it over. 👨‍🦳 Uncle: That's it. That's the entire job of a server handling a request. You don't need to understand Amazon's warehouse to understand Amazon's problems. You need a counter and a storeroom, imagined clearly, and the patience to grow them one honest problem at a time. Here's the shape of what you just described, whether you realized it or not: 🧍 Customer 🧑 You (Counter) 📦 Storeroom (Database) | | | |── "Got Maggi?" ───────>| | | |──── Walk in, search ────────>| | |<─────── Found it ────────────| |<── Hand it over, ──────| | | take payment | | 👨‍🦳 Uncle: One customer, one request, one trip to the storeroom, one response. This is fine. This is correct , even, for a shop with five customers a day. Don't let anyone tell you a single counter isn't "scalable" — a shop that small doesn't need two counters, it needs someone to stop worrying and open the shutter. 👦 Nephew: So this is just... a server handling one request at a time? 👨‍🦳 Uncle: Exactly. Customer sen

Migration guidance and evolution specifications are also provided. By Daniel Curtis

สวัสดีครับเพื่อนๆ! 👋 วันนี้จะมาเล่าเรื่องน่าตื่นเต้นให้ฟังนะเพื่อนๆ สำหรับใครที่เป็นสาย SvelteKit เตรียมตัวอัปเดตความรู้ใหม่กันได้เลย เพราะตอนนี้เขามีของเล่นใหม่ที่กำลังอยู่ในช่วงทดลองใช้งาน แต่บอกเลยว่าว้าวมาก! เราไปดูกันดีกว่าว่ามันคืออะไร... 📡 Remote function คืออะไร เป็น function ตัวใหม่ ✨ (ที่คาดว่าจะเป็น new way to implement สำหรับ Sveltekit 3.0) เอาไว้ใช้สื่อสารพูดคุยกันระหว่างฝั่ง client และ server ของ Sveltekit นั่นเอง 💬 ความเจ๋งคือเราสามารถเรียกใช้มันจากมุมไหนของ Sveltekit ก็ได้ 🌍 ไม่จำเป็นต้องจำกัดแค่ฝั่ง server หรือ client แต่จุดสำคัญคือ การทำงานของมันจะเกิดขึ้นที่ฝั่ง server เสมอ 👍 นั่นหมายความว่ามันสามารถทะลุทะลวงไปดึงข้อมูลหรือโมดูลที่เป็น server-only ได้สบายๆ เช่น ตัวแปร environment ที่เราประกาศไว้ หรือพวกฐานข้อมูลต่างๆ ก็ดึงมาได้ชิลๆ เลย 😎 เวลาจะใช้งาน เราจะต้องใช้ท่าการ await แบบใหม่ของ Sveltekit ⏳ ที่ช่วยให้คุณโหลดหรือดึงข้อมูลแบบ promise มาใช้ใน component ของคุณได้ทันที 🚀 ⚠️ หมายเหตุ: ตอนนี้ทั้ง await และ remote function ยังอยู่ในช่วงทดลองใช้งาน 🧪 (experimental) นั่นแปลว่า syntax บางอย่างอาจจะมีการปรับเปลี่ยนหรือบินหายไปบ้างในอนาคต 🥲 แต่แกนหลัก (core functional) ของมันก็จะยังทำงานได้ตามที่เราคาดหวังแน่นอน ถ้าใครคันไม้คันมืออยากลองของใหม่ตอนนี้ สามารถไปเปิดโหมด experimental ได้ที่ไฟล์ svelte.config.js(.ts) ตามโค้ดด้านล่างนี้เลย 👇 svelte.config.js(.ts) /** @type {import('@sveltejs/kit').Config} */ const config = { kit : { experimental : { remoteFunctions : true } }, compilerOptions : { experimental : { async : true } } }; export default config ; 🏃‍♂️ Let get started!! เราสามารถเริ่มใช้ remote function ได้ง่ายๆ ผ่านการสร้างไฟล์นามสกุล .remote.js หรือ .remote.ts 📝 ซึ่งตอนนี้มี function ให้เราหยิบมาเล่นทั้งหมด 4 ตัวด้วยกันคือ: query (ที่เราจะมาพูดถึงกันในบทความนี้) form command prerender หลักการทำงานเบื้องหลังคือ เวลาที่เรา import ตัว remote function ไปใช้ในฝั่ง client มันจะถูกแอบแปลงร่างเป็นโค้ดที่หุ้มด้วย fetch ในช่วง build time 🏗️ นั่นหมายความว่าระบบจะใจดีสร้างเส้น HTTP endpoint ให้เราแบบอัตโนมัติ ✨ ด้วยเหตุนี้เราเลยเอาไฟล์ .remote.js หรือ .remote.

The trust problem nobody scopes correctly When companies talk about trust in AI, they almost always mean trust in the model. Is the output accurate? Is it hallucinating? Can we rely on what it says? Those are valid questions but they're the wrong starting point. The trust that actually determines whether AI gets adopted or quietly abandoned inside an organization isn't about the model. It's about the system surrounding it. The four questions that determine Every team evaluating AI in a production workflow eventually runs into the same four questions. Not about model quality. About operational control. Can we understand the outputs? Not just "does the answer look right" but can someone on the team explain why this output was produced and whether it's appropriate for this specific context. An AI that generates correct-looking code or recommendations that nobody can verify is a system that runs on hope. Hope doesn't survive the first incident. Can we validate the decisions? When the AI recommends an action or generates an output that feeds into a business process, is there a way to check it against the actual requirement? Or does the team just trust the output because questioning it is harder than accepting it? The second one is more common than anyone admits. Can we intervene when needed? When something goes wrong, how fast can a human step in? Is there a kill switch? Is there a fallback path? Or does the AI output flow directly into downstream systems with no circuit breaker? The teams that skip this question are the ones that discover the answer during an incident. Can we trace what happened afterward? When an AI-generated decision produces a bad outcome, can you reconstruct the chain? What input went in, what output came out, what context was available, what wasn't? Without traceability, post-mortems hit a dead end, and the same failure happens again. Why opaque systems don't survive real operations There's a tempting argument that opacity is fine as long as the sy

Laravel middleware can be perfectly written and still behave unexpectedly. You may notice authentication running too late, permission checks failing, tenant initialization not working, logging middleware missing important data, or custom middleware executing in an order you didn't expect. In many cases, the middleware code itself is not the problem. The real issue is middleware execution order. Understanding how Laravel executes middleware is critical when building secure and scalable applications because every request passes through multiple layers before reaching your controller. Common Symptoms You may encounter problems such as: Authenticated users being treated as guests Permission middleware failing unexpectedly Tenant information not being available Request logging missing user details Rate limiting triggering before authentication Redirect loops after login Middleware appearing to be ignored completely These issues are often caused by middleware running in the wrong sequence. How Laravel Processes a Request A typical Laravel request follows this flow: Browser ↓ Global Middleware ↓ Middleware Group (Web/API) ↓ Route Middleware ↓ Controller ↓ Response ↓ Browser Each middleware layer can inspect, modify, allow, or block the request before it reaches your application logic. Because of this, execution order matters. Example Problem #1 Suppose you have two middleware: Authenticate User Log User Activity Your logging middleware expects an authenticated user. $user = auth()->user(); However, the log always shows null. Why? Because the logging middleware executes before authentication. The solution is ensuring authentication middleware runs first so user information is available when logging occurs. Example Problem #2 Multi-tenant applications often initialize tenant information through middleware. TenantMiddleware If another middleware accesses the database before tenant initialization, queries may use the wrong database connection. This can lead to: Incorrect data

I recently built a free online image processing tool that runs entirely in the browser. No uploads, no servers, no sign-ups. Here's how it works under the hood. https://img.aixiaot.com The Problem Most online image tools require uploading your photos to someone else's server. This raises privacy concerns and limits file sizes. I wanted to build something that processes everything locally. Tech Stack - Next.js for the frontend - TensorFlow.js + Real-ESRGAN for AI upscaling - @imgly/background-removal for AI background removal - Tesseract.js for OCR - Canvas API for compression, resizing, format conversion Features • AI Background Removal - one click, works for portraits, products, animals • Image Compression - reduce file size up to 96% • Format Conversion - JPG, PNG, WebP • ID Photo Maker - passport and visa photos with customizable backgrounds • AI Image Upscaler - 2x to 8x with Real-ESRGAN • OCR - extract text from images, 20+ languages • Image Resizer - enlarge or shrink Architecture All processing happens client-side using WebAssembly and the Canvas API. When you upload an image, it never leaves your device. The AI models (background removal, upscaling) run locally in your browser using TensorFlow.js and ONNX Runtime Web. Open Source The entire project is open source under AGPL v3. You can find it on GitHub: https://github.com/haizeigh/ai-image-tools Try It https://img.aixiaot.com I'd love to hear your feedback! What features would you add?

One question I get surprisingly often is: "How do you manage thousands of AI prompts without losing track of them?" The answer is simple. I don't treat prompts as conversations. I treat them as reusable software assets. Over the years, I've created prompt libraries across multiple AI projects, books, research initiatives, and client work. That means managing well over 10,000 prompts covering everything from Python development and AI agents to content generation and workflow automation. If you're still storing prompts in random ChatGPT conversations, you're making life much harder than it needs to be. Here's the system that works for me. Stop Thinking of Prompts as Temporary Most people write a prompt, get an answer, and move on. That's fine for casual use. But builders rarely solve the same problem only once. If you find yourself writing: API documentation SQL queries FastAPI endpoints Docker configurations Code reviews Git commit messages ...you're probably solving recurring problems. Recurring problems deserve reusable prompts. My Folder Structure Instead of organizing prompts by AI tool, I organize them by purpose. For example: AI-Prompts/ │ ├── Python/ │ ├── FastAPI │ ├── Django │ ├── Flask │ └── Automation │ ├── JavaScript/ │ ├── React │ ├── Node.js │ └── TypeScript │ ├── DevOps/ │ ├── Docker │ ├── Kubernetes │ └── GitHub Actions │ ├── AI/ │ ├── RAG │ ├── Agents │ ├── MCP │ └── Prompt Engineering │ └── Documentation/ This mirrors how software projects are organized. Finding a prompt takes seconds. Every Prompt Has Metadata A prompt isn't just text. It's documentation. Each prompt in my library includes: Category: Purpose: Model: Input: Expected Output: Version: Last Updated: For example: Category: FastAPI Purpose: Generate CRUD endpoints Model: GPT-4o Expected Output: Production-ready FastAPI code Six months later, I know exactly why that prompt exists. I Version My Prompts Developers version code. Why not prompts? For example: FastAPI_CRUD_v1.md FastAPI_CRUD_v

Base64 image data URIs are one of those web techniques that look like a magic shortcut the first time you use them. Instead of referencing an external file: <img src= "/logo.png" alt= "Logo" > you can put the image bytes directly in the document as text: <img src= "data:image/png;base64,iVBORw0KGgoAAAANSUhEUg..." alt= "Logo" > That can be useful. It can also make a page slower, harder to cache, and more annoying to maintain. Here is the practical rule: inline images as Base64 when self-containment matters more than caching. Keep normal image files when the browser should be able to cache, resize, lazy-load, or optimize them independently. What a Base64 image actually is An image file is binary data. Base64 rewrites that binary data as plain text using a limited character set. To make the browser treat the text as an image, you wrap it in a data URI: data:image/png;base64,iVBORw0KGgoAAAANSUhEUg... The first part tells the browser the MIME type. The second part tells it the data is Base64 encoded. The long tail is the image itself. Base64 is not compression. It is not encryption. It is just a text representation of the same bytes. When inlining an image is worth it 1. Tiny icons and UI assets For very small images, removing an extra HTTP request can be worth the extra bytes. This is especially true for small icons, logos, placeholders, simple UI sprites, or tiny transparent PNGs. Modern HTTP/2 and HTTP/3 make extra requests cheaper than they used to be, so this is not an automatic win. But for a one-off tiny asset inside a small page or widget, a data URI can still be a clean choice. 2. Single-file deliverables Sometimes the point is not raw page speed. Sometimes you need one file that carries everything with it: an HTML report an email template a CodePen or demo snippet a CMS block where you cannot upload assets a test fixture that should not depend on external hosting In those cases, Base64 is useful because the image travels with the HTML, CSS, JSON, or JavaScript.
