As developers, we waste hours every week on repetitive tasks: formatting JSON, converting timestamps, generating passwords, and compressing images. We hunt for scattered tools across the web, each requiring signup, login, and often subscription fees.What if there was a single toolbox with 30+ free t
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
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
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
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
Part 1 of a 2-part series. This post covers the whole tool and the "one source of truth" problem. Part 2 goes deep on the most novel piece — letting your npm packages ship agent skills. (dev.to shows the series navigation once Part 2 is published.) TL;DR Write project instructions once in AGENTS.md
SOLID Principles in Ruby on Rails SOLID is not a Rails or Ruby concept. It's a set of five object-oriented design principles that apply to any language/framework. But Rails makes it surprisingly easy to violate all five of them. Let's start with It states a class should have only one reason to chang
Three weeks ago, I stopped writing to watch history unfold. What I witnessed in those twenty-one days changed everything I thought I knew about software development. An engineer at a Fortune 100 company reduced a nine-day pull request cycle to 2.4 days. A Latin American fintech company completed an
Hello, I'm Ganesh. I'm building git-lrc, an AI code reviewer that runs on every commit. It is free, unlimited, and source-available on Github. Star git-lrc on GitHub to help more developers discover the project. Do give it a try and share your feedback for improving the product. While playing with n
Start with a simple schema: { "$schema": "https://json-schema.org/draft/2020-12/schema", "title": "Order", "type": "object", "required": ["id", "amount", "customer"], "properties": { "id": { "type": "string" }, "amount": { "type": "number" }, "customer": { "type": "object", "properties": { "email":
The artificial intelligence coding revolution comes with a catch: it's expensive. Claude Code, Anthropic's terminal-based AI agent that can write, debug, and deploy code autonomously, has captured the imagination of software developers worldwide. But its pricing — ranging from $20 to $200 per month
