Closure: o que o JavaScript se recusa a deixar pra trás

Introdução Closure é um comportamento padrão de toda função JavaScript e por isso é um assunto fundamental quando trabalhamos com essa linguagem. No entanto, o mais interessante sobre esse conceito, é entender quando sua aplicação pode de fato trazer um diferencial para o nosso código ou não. Para entender Closure, vamos primeiro revisar os conceitos abaixo. Caso já tenha conhecimento sobre eles, fique a vontade para pulá-los. Escopo Léxico x Escopo Dinâmico Contexto de Execução Funções Aninha

Beyond Binary Input: The Engineering Cost of the Analog Keyboard Paradigm Shift

Beyond Binary Input: The Engineering Cost of the Analog Keyboard Paradigm Shift The recent market discounting of premium peripherals, such as Razer’s Huntsman V3 Pro, signals more than a standard retail cycle; it marks the commoditization of a fundamental shift in human-computer interface (HCI) technology. For decades, the mechanical keyboard market operated on a binary paradigm: a copper leaf made physical contact, closed a circuit, and triggered a hardware interrupt. The rise of analog optic

The Laws That Quietly Govern Good Software (Part One)

"We'll clean it up later." In my last post, I wrote about the hidden complexity behind simple products. The short version: great software feels effortless because someone chose to carry the complexity for you. This post is about how engineers learn to carry it. Not through frameworks. Not through tools. Through a small set of laws that keep showing up, decade after decade, in every codebase and every team. Most of them were written before I was born. All of them are still true. I found a wonderf

Paving the wrong Path: What a Broken Government System Taught Me About Feedback Loops

Last year I was made redundant from an NHS role. Around the same time, the team I worked in got a "new system." Everything that used to live on paper — or, honestly, in something that behaved like a shared Excel sheet — was going digital. I was still employed during the first few weeks of rollout, so I watched it happen. And the thing I remember most clearly is that it didn't make anything better. The forms moved from paper to screen, and that was more or less the whole story. The same duplicati
