Debug Your Website's Issues with Print Statements and a Debugger

Real talk: You’re debugging for hours because you guess instead of checking. No logs. No clear errors. Fix: - Log important actions - Print actual error messages - Check logs before changing code Stop guessing. Start seeing. #Debugging #WebDev #DevTips #Backend

Imagine this: You’re debugging a critical issue, and your log file has 1GB+ and thousands of lines. Your tool? Notepad++. Sound familiar? A few years ago, I used an internal log viewer built by one of the developers at my company. It was fast, simple, and incredibly useful. Then I changed jobs. And suddenly… I didn’t have anything like it anymore. In most places I worked after that, debugging logs often meant using tools like Notepad++. Which works — but isn’t the most convenient when you’re dealing with thousands… or hundreds of thousands of lines. And definitely not when files grow to gigabytes. A few months ago, I decided to learn JavaScript and started with a simple experiment: build a basic file viewer that runs in the browser. When I saw the potential, I started thinking — what if this could work more like something between Monaco Editor and CodeMirror, but optimized for huge files? That led me down a deeper rabbit hole. I moved the core to C++ and compiled it to WebAssembly. And eventually ended up building a custom rendering engine focused on: * low memory usage * modularity * handling extremely large files with high responsiveness The result? FlixLines - a browser-based log viewer that: ✅ Opens multi-GB files (tested up to 20GB) instantly ✅ Scrolls smoothly at 60–160 FPS (yes, even for huge files!) ✅ Runs entirely on the client side — no backend, no uploads, no waiting ✅ Highlights syntax, detects patterns, and lets you bookmark lines ✅ Keeps everything local (no data leaves your machine) Where could this help? ✅ DevOps teams debugging server logs during outages ✅ Embedded devs analyzing firmware logs on air-gapped systems ✅ Security researchers parsing massive log dumps without risking leaks If you’ve ever struggled with giant logs, I’d love to hear: ✅ What’s your current workflow? (Notepad++? grep? Something else?) ✅ What’s the most painful part of working with large logs? Try the demo (works best on Chrome): https://lnkd.in/dXRFqb9K Or drop a comment — let’s discuss how we can make log analysis less painful!" #JavaScript #Emscripten #WebAssembly #V8 #Performance

Analyzing very large log files is still, in many places, a time-consuming and inconvenient process, which is why an approach focused on performance, high responsiveness, and fully local processing brings real value here. It is also worth highlighting the solid technical foundation and the clear focus on solving a specific, real user problem. This project is definitely worth checking out, trying the demo, and following as it continues to develop. 👍

Vite 8.0 is out: What’s new and why it matters 🧑💻 Recently, Vite released version 8 with a new bundler, Rolldown, introducing a major architectural shift. Earlier, Vite relied on: • esbuild for development • Rollup for production We no longer need separate bundlers for development and production. Vite is moving toward a unified approach with Rolldown, a Rust-based bundler designed for better performance and scalability, delivering significantly faster builds (up to 10–30x compared to Rollup). What I found even more interesting is a smaller (but impactful) change 🤔 Browser console logs can now be forwarded directly to the terminal (like VS Code, Cursor and other IDEs). 💡 Why this matters Browser errors can now be seen directly in the terminal, enabling faster debugging without switching to the browser and improving modern workflows where tools (including AI-assisted tools like Cursor, Claude, Codex and Copilot) can access these errors more directly in the terminal. As AI becomes a bigger part of development, tools are evolving fast. It will be interesting to see how other tools evolve in the future. #Vite #JavaScript #ReactJS #DeveloperExperience #WebDevelopment #FrontendDevelopment #FullStackDeveloper #SoftwareEngineering

🔧 A tool that improved my debugging speed. Today I relied heavily on browser DevTools. 🔍 Used for: • Inspecting elements • Tracking network calls • Debugging JavaScript ✅ Saved a lot of time. 💡 Learning: Right tools can 10x your productivity. #Frontend #Debugging #Tools

Vite 8 is officially here (March 2026) and it’s a GAME CHANGER for developers. Here’s why 👇 ⚡ 10–30x faster builds 🧠 New Rust-based bundler (Rolldown) 🔄 No more dev vs prod inconsistencies 🧰 Built-in DevTools & TS path support 🔌 Works with existing plugins The biggest shift? 👉 Vite moved from a dual bundler system (esbuild + Rollup) to a single unified engine. This means: ✔ Faster builds ✔ Cleaner architecture ✔ Better debugging ✔ More predictable behavior 💡 In short: Vite 8 isn’t just faster — it’s more reliable and future-proof. If you are still using older one, then you can check this new Vite version. #vite #frontend #webdevelopment #react #javascript #devtools #performance

For developers running Wheels 3.x and weighing a 4.0 upgrade, I've published a row-by-row before/after comparison. The doc only covers capabilities that actually changed between the 3.0.0 release and 4.0 — unchanged rows are omitted so the scope of the upgrade is legible at a glance. Every row carries a tag that indicates what kind of change it is: - New — capability did not exist in 3.0 - Formalized — had partial or undocumented precedent; now production-ready with tests and official docs - Hardened — existed; security-tightened in 4.0 - Fixed — bug that made the 3.0 capability unreliable; resolved in 4.0 - Breaking — default behavior changed in a way that requires user action when upgrading - Removed — 3.0 surface removed entirely By the numbers: approximately 40 new capabilities (including `wheels deploy`, a first-class Kamal-style deploy tool added late in the cycle), 11 formalizations, 7 breaking defaults hardened (each with an opt-out), and 4 legacy surfaces removed. The doc pairs with the upgrade guide, which walks each of the 7 breaking changes with detect, fix, and opt-out guidance. https://lnkd.in/gJ7cP7Fk #CFML #Wheels #Upgrade #ReleaseNotes #OpenSource

There’s a special kind of bug every developer knows… The one that disappears the moment you open Inspect. You refresh → it’s broken. You open DevTools → it magically fixes itself. You close it → broken again. At that point, you’re not even debugging anymore… you’re negotiating with the browser 😅 It’s funny, but it also taught me something: Sometimes the issue isn’t just your code. It’s caching, rendering timing, extensions, or the environment behaving differently. What helped me: – Testing in different browsers – Clearing cache (way more often than I’d like) – Checking without extensions – Slowing down and isolating the problem step by step Because not every bug is loud. Some of them only show up when you’re not looking.

Every few months someone posts this in a dev Discord: "I've been running FFmpeg on a VPS for a year. It's been a nightmare." It's not a skills problem. It's a scale problem. FFmpeg is genuinely impressive software. It handles basically everything you'd want to do with video. But wrapping it in something production-ready is its own job: - Jobs time out under load - Memory spikes on longer files - Queue management becomes a project in itself - You're debugging server config instead of shipping features The pattern is always the same. A quick script works fine at low volume. Traffic picks up, things break in new ways. You spend a week firefighting. Then it happens again. At some point the question stops being "how do I process this video?" and becomes "how do I maintain this processing infrastructure?" Those are very different jobs. The reason devs kept building their own: video APIs used to be expensive, flaky, or too limited. That calculus is changing. Command-based pricing, zero egress fees, and stable results at scale have made "just use an API" a real option for most projects. If you're still running your own FFmpeg server, it might be worth doing the math on what that ops time actually costs. renderio.dev #FFmpeg #VideoAPI #DeveloperExperience #VideoProcessing #DevTools

I kept talking about “build your own gstack”. So I did. Introducing "shft-stack". Not trying to be Garry’s setup. Not trying to be perfect. Just something that fits how I think, build and ship. Simple. Iterative. No fake roles. No overthinking. This will probably evolve every few weeks and that’s the point. Steal ideas. Break them. Rebuild for your context. What does your stack look like? 🔗 https://lnkd.in/gxavdpeP #workflow #solo #builder
