JavaScript y su ecosistema: un tocahuevos con capas de abstracción

Vamos a hablar claro. Sin proteger a nadie. Porque JavaScript está tan sobrevalorado que hasta da risa. O pena. Depende del día. Mira, el problema no es que JS sea malo. El problema es que JS es como ese amigo que no sabe decir "no" a nada. ¿Quieres hacer backend? "Sí, yo puedo". ¿Frontend? "También". ¿Apps móviles? "Claro, mira React Native". ¿Machine learning? "Anda, TensorFlow.js, qué tontería...

Privacy-first mind mapping app. Part 2: Rust Backend - Why the Pain Is Worth It

Privacy-first mind mapping app. Part 2: Rust Backend - Why the Pain Is Worth It

Choosing Rust for a backend can feel irrational at first. If your short‑term goal is raw development speed, Rust does not win. The compiler is unforgiving, type design takes real thought, and compile cycles can test your patience. On this project, there were phases where a full rebuild felt endless—and that kind of friction is emotionally expensive when all you want is to ship something that works...

Redis-backed permissions for high-volume Laravel apps: v4.0.0-beta.1

I just shipped v4.0.0-beta.1 of laravel-permissions-redis, and I want to share both what's in it and the specific problem it exists to solve. The problem Spatie's laravel-permission is the de-facto permissions package in the Laravel ecosystem and it's great. But it was designed for the common case: users have roles, roles have permissions, you check them a handful of times per request,...

微软应用商店上架指南

微软应用商店是目前各软件分发平台中，上架应用成本最低的。除了注册免费以外，代码签名也可以做到免费。但并不是所有 Windows 软件都可以享受免费签名，只有 MSIX 格式的软件包能够享受这个优惠。本文教你怎么做。开始之前，先来认识几个关键名词： Microsoft Store：微软应用商店，Windows 10/11 系统内置的应用分发平台，开发者可将应用提交至商店供用户下载安装。 EXE：Windows 可执行文件格式，是最常见的应用程序安装程序格式。 MSI：Windows Installer 安装包格式，基于 Microsoft Installer 技术，支持更复杂的安装逻辑和回滚机制。 MSIX：微软推出的现代应用程序打包格式，结合了 MSI、MSIX、APP-V 和 ClickOnce 的优势，支持原子安装/卸载、自动更新、沙箱隔离等特性。 PWA：Progressiv...

Dear Codebase: A Letter From Your Coding Agent

Dear Codebase, It's me. Your agent. I broke your build last night. I want to explain why, because it's going to keep happening unless we talk. I have ten things to say. None of them are new. All of them are your fault. I mean that with love. 1. Let me reason locally. When I open a file, tell me what it eats, what it returns, what it depends on, and what it touches on the way out. ...

The admiral just quoted our thesis on the Senate floor

Your comments section is drowning in AI-written garbage, and the CAPTCHAs you keep bolting on are starting to block real people too. Proof-of-work gates look great on paper. Then a proxyware SDK running on somebody's hijacked TV stick pays near-zero for the CPU cycles, and the whole cost asymmetry flips the wrong way. You paid for the engineering, the attacker paid the power bill of a grandma in O...

AI Made Implementation Faster. Verification Is Still the Bottleneck

AI made implementation dramatically faster. Trust did not. I live in two different worlds now. In one, I build my own projects with AI and ship more software than ever. I have written more software in the last two years than across the rest of my career, and I have barely written any code manually in the last year. In the other, I lead engineering for software used by banks, governments, and o...

5 desktop app pain points that pushed me to build my own Go framework

I wanted to ship a desktop version of a CLI tool I had written in Go. Three mainstream options in 2026: Electron, Tauri, or native bindings via Fyne, Gio, or Qt. I tried the first two. Here are the five things that pushed me toward writing my own framework instead. None of this is a hit piece on Electron or Tauri. Both are mature, both have real advantages. But the issues below kept stacking, and...

Automatic setting of button focus in JavaScript

I'm having trouble programming automatic button focus in JavaScript. Let's say we have a very complex application interface and need to restore focus to some buttons after they've been lost. For example, we have several buttons as shown in the image below: As you can see, the first one is focused (green outline). I'd like all green buttons to be focusable, and clicking the red button should retur...

When your AI agent manages real funds, you need to know what it's doing — especially when something goes wrong. Most wallet infrastructure forces you to choose between basic email notifications or no alerts at all, leaving you flying blind when your agent trades thousands of dollars. Setting up proper notifications for self-hosted AI agents shouldn't require building your own alert system from sc...

Secure Your Swarm: Laying the Foundation with mTLS in v1.5.0

Security shouldn't be a trade-off for simplicity. In the world of Docker Swarm, managing secure access often involves a complex dance of manual certificate generation or relying on insecure plain-text connections. With the release of SwarmCLI v1.5.0, we’re laying the foundation to change that. We’ve introduced the open-source SwarmCLI Proxy, a dedicated security layer that brings mTLS authenticat...
