Eu achava que Node.js era o “Django do JavaScript”… até entender isso

Se você está começando no desenvolvimento web, deixa eu tentar adivinhar: Em algum momento você pensou algo como: “Se Django é o principal framework do Python… então Node.js deve ser tipo isso pro JavaScript, né?” Eu também pensei assim. E foi aí que começou a confusão. 🤯 O momento em que tudo não fez sentido Eu comecei a pesquisar sobre backend e vi coisas como: Node.js Exp...

How to Use Rails Magic Methods in Plain Ruby Scripts

Very often I find myself writing small, standalone Ruby scripts. Maybe it's a web scraper, a small background worker, or a quick Sinatra API. I start typing out my code, and naturally, I write something like this: if my_variable.present? puts "We have data!" end And immediately, my script crashes with NoMethodError: undefined method 'present?' for nil:NilClass. This is the moment ev...

My 3-Month Startup Directory Submission Journey — What Actually Moved the Needle

Over the last few months I submitted five websites to every free startup directory I could find. Not as a theoretical exercise — I needed backlinks. My domain rating was stuck at 20 and organic traffic was flat. Here is what actually happened. Month 1: The Naive Phase I found a few GitHub repos listing 300+ directories and started submitting to everything. No filtering, no strategy. J...

DualClip: multi-slot clipboard manager for macOS

First project with macOS & Swift I wanted to share DualClip, a native macOS menu bar app I’ve been working on. While there are many great clipboard managers like Maccy or Paste, I found that most of them focus on "History"—searching through a vertical list of everything you've copied. I built DualClip because I needed something that works more like a "Workbench." Instead of picking from a m...

The hidden system behind Tesla autonomy

Why feature stores matter more than the models Everyone thinks Tesla wins because they have better AI. That's only part of the story. The real edge isn't the model sitting at the center of Autopilot. It's the infrastructure that feeds it, the system that takes raw, messy sensor data from the physical world and turns it into something a neural network can actually reason about. ...

15 Open Source AI Code Review Tools (2026)

Why open source code review matters Choosing an open source code review tool is not just about saving money - it is about control. When your code review infrastructure is proprietary, you are trusting a vendor with your most sensitive asset: your source code. Every pull request, every diff, every comment passes through servers you do not own. For teams working on regulated software, def...

Get Started with Claude Code: A Developer's First Look at AI-Powered Coding

Introduction There are a lot of AI tools out there. Claude.ai, GitHub Copilot, Cursor, ChatGPT — the list keeps growing. So when I sat down to explore Claude Code, I had one question in mind: what actually makes this different? By the end of this project, I had a working portfolio website — built almost entirely by AI — and a clearer picture of where Claude Code shines. Here's exactly what I lea...

Part I: Terms, Origins, and Paradigm Shifts

When a change truly begins to enter reality, what changes first is often not the tools, but the language. The old vocabulary is still there, yet people feel with increasing frequency that it is no longer sufficient. The problem clearly lies in knowledge entry points, verification loops, handoff structure, and responsibility boundaries, but teams still use prompt quality, the number of tools, and ...

Scaling code reviews with an Open Source AI Skill

With the rise of AI-generated code, reviewing pull requests has become more challenging than before. On several projects, I noticed the same pattern. Pull requests were getting bigger and more frequent, which made reviewing thoroughly increasingly difficult. The challenge was not complexity but volume. With AI accelerating code production, the gap became obvious. We can generate code fast, but r...

Claude Code parallel agents: run 4 tasks simultaneously and merge with git

Claude Code parallel agents: run 4 tasks simultaneously and merge with git One of the most underused Claude Code patterns is parallel subagents. Instead of waiting for Claude to finish one task before starting the next, you can spawn multiple agents working simultaneously — then merge. Here's how to actually do it. The problem with sequential Claude Code Default Claude Code...

Your e-shop data lives in three places that don't talk to each other

I recently scoped a project for an e-commerce client running PrestaShop. Smart guy, profitable business, good product margins. He had one question he couldn't answer: which of his Google Ads campaigns actually make money? Not which ones get clicks. Not which ones drive traffic. Which ones drive purchases of products with margins high enough to justify the ad spend? He'd been running Google Ads fo...

The prompt is the product

TLDR: Don't ask AI to do the thing directly. Ask it to interview you first — what are your constraints, what have you not thought of, what would you recommend? Collect those answers into a brief. Use that brief as your real prompt. This works for anything: websites, business plans, marketing campaigns, internal tools, hiring processes. The example below is a website, but the method is universal. A...
