Error Handling in Node.js: Beyond Try/Catch (2026) Good error handling isn't about catching errors — it's about handling them gracefully so your app stays running. Bad error handling: → try/catch everything silently → bugs disappear, no one knows why → console.error(err) and move on → logs nobody re
Git Advanced: The Commands I Wish I Knew Earlier (2026) Beyond commit, push, and pull. These are the commands that make you significantly more productive. # Amend the last commit (fix typo, add forgotten file) git commit --amend -m "Better message" # or: git add forgotten-file && git commit --amend
Aprendi as coisas mais fascinantes que sei com as lendas da cultura hacker. Minha base técnica e moral foi forjada lendo os manifestos da FSF e entendendo a elegância absoluta da filosofia Unix — a magia dos pipes, o princípio de "fazer uma única coisa e fazê-la muito bem". Historicamente, o legado
The Layer Responsible for End-to-End Communication Imagine ordering a package online. Would you rather: Receive it slowly but guaranteed? Receive it instantly with no guarantee it arrives? Different situations demand different answers. A bank transaction requires absolute reliability. A live video s
While working in VS Code, I occasionally need sequential numbers. Something like this: user_001 user_002 user_003 Or test data for SQL: INSERT INTO users(id, name, created_at) VALUES(1, 'testA', '2026-05-28 10:00:00'); INSERT INTO users(id, name, created_at) VALUES(2, 'testB', '2026-05-28 10:00:01')
How to optimize application performance — a hands on tutorial Performance Optimization: Measure Before You Optimize Donald Knuth's famous warning-"premature optimization is the root of all evil"-boils down to one principle: measure before optimizing. Without real-world evidence that your application
Dynamic memory allocation in C is flexible, but it becomes a bottleneck in systems where objects are created and destroyed frequently. Repeated malloc/free calls can introduce overhead, fragmentation, and unpredictable latency. To avoid that, I built a small object pool in C89. The idea is simple: i
Introduction In my previous article, I wrote about delegating the entire management of my home server to an AI. The system is designed so that the AI performs patrols late at night, and during the day, it springs into action if monitoring scripts detect any anomalies. I explained how I built the sys
This is a submission for the Hermes Agent Challenge AI agents extend traditional LLMs by combining reasoning, memory, and tools to execute tasks autonomously. Instead of only generating responses, they can interact with external systems, maintain context across sessions, and perform multi-step workf
The 9 ms wall PHP can't break Every viral video we surface at ViralVidVault carries about 14 fields of metadata - view counts, channel handles, duration, age-restriction flags, regional availability, the music license shape that Cloudflare Workers in our edge filter cares about. The PHP 8.4 + SQLite
Microservices architecture has evolved from a buzzword to a fundamental paradigm for building distributed systems at scale. The core premise is straightforward: decompose your application into independently deployable services that communicate over the network, each owning its own data domain and bu
I've been building web scrapers for years. BeautifulSoup, Scrapy, Selenium — I've used them all. But last month I hit a wall. A client needed me to extract product data from a site that changed its HTML structure every few days. One week the price was in a , the next it was inside a with a random ID

Have you ever set up a CLAUDE.md file, dropped in 200 lines of rules, and then watched the AI completely ignore half of them anyway? You are not alone. The irony of writing instructions for AI coding assistants is that the same productivity trap applies to you: more rules ≠ better results. Here are
Your .cursorrules file is probably not working the way you think it is. Not because Cursor is broken — but because most .cursorrules setups make the same five mistakes. Here is what they are and how to fix them. The most common .cursorrules antipattern is the monolith: one file at the project root,
Most developers think of project setup as: install dependencies, configure TypeScript, set up linting. That is the wrong order. The AI-native setup order is different, and skipping it means your AI assistant works against your project instead of with it. Here are the three files that should exist be
Enterprise AI agents are stalling — not because of model performance, but because of permissioning. Every agentic workflow eventually hits the same wall: what is this agent allowed to touch, on whose behalf, and how does the system know? Workday's answer is to make its existing system of record the
How to use LLMs effectively in your daily work — a practical tutorial 1. Core principles for dev work LLMs are best at transforming and iterating on artifacts (requirements → design, design → code, code → tests, code → docs). You get better results from small, focused prompts than from “build my who
Hey devs! 👋 We all handle a massive amount of text data every single day. Whether it's formatting a messy JSON payload, reversing a string, checking a cryptographic binary sequence, or just fixing case errors in code comments, text utility sites are deeply integrated into our workflows. But here is
Analyst Ming-Chi Kuo is out with a new look at Apple’s upcoming iPhone camera plans, including an under-the-hood ultra-wide module change and a surprisingly steep cost increase. Here are the details. more…
