Build a tiny web server in C (from scratch) Let’s serve index.html over HTTP using raw sockets. ~100 lines, pure C. Perfect to learn sockets + HTTP basics.

That's neat, @lisyarus! But it's just the first step of the journey. Next, try the hidden C/C++ gnome operators `<:]` and `<:0]`, which go hand-in-hand with the converges-to operator. 🧙‍♂️ Veteran developers will hate me for revealing this trick. Here's how it works: 🧵 1/5

Meet Pulsar: your haptic presets library for Swift, Kotlin, and React Native! 🚀 👉 150+ free patterns you can browse, filter, preview, and ship in minutes 👉 Audio preview of each preset so you can test it on a simulator without deploying 👉 Playground and app that let you feel the haptics on your phone

📦 Shaders - Component library for creative WebGPU effects I just gave it a try, and it looks quite nice to achieve interesting, creative results Just by composing React components There's a paid offering (editor, presets), but you can use this for free in commercial projects

Since I'm teaching C++ I can just straight up tell the students about the "converges to" operator

React Native 0.85 is now available! This release includes the New Animation Backend, selection data in TextInput onChange events, Metro TLS support, and moves the Jest preset to a dedicated package. reactnative.dev/blog/2026/04/0…

This is a common C++ gotcha. That’s why you should use platform-independent integral types.

C++ design patterns for low-latency applications, including HFT. Mostly perf optimizations familiar from advanced compilers/OS courses - still a good intro if you're trying to build intuition around performance. arxiv.org/pdf/2309.04259

在移动端界面里渲染数学公式，绕不开 WebView 这个坑。一个公式背后藏着整个浏览器引擎，内存占用大，启动还慢。 偶然看到 RaTeX 这个项目，用纯 Rust 写了一套数学公式渲染引擎，彻底甩掉了 JavaScript 和 WebView。 一套核心代码，覆盖 iOS、Android、Flutter、React Native、Web、PNG、SVG 七个平台，全部原生渲染，零 JS 依赖。 GitHub：github.com/erweixin/RaTeX 语法兼容 KaTeX 约 99% 的写法，分数、根号、积分、矩阵这些都能渲染。 还支持化学方程式和物理单位的书写，理工科场景基本够用。 完全离线可用，如果你在做教育类或学术类 App，想摆脱 WebView 渲染公式的传统笨重方案，这个项目值得试试。

github.com/Doko-Demo-Doa/… I've created a library that provides a single async API that opens native picker and returns structured country data. Including calling code and country code.

every skeleton screen you've ever hand-coded is a waste of time you're literally measuring padding and guessing widths to build a worse version of a layout that already exists in your DOM so I made a package that just reads the real one

Interviewer: you need to find duplicates in 1M records, memory is limited. what approach do you use?
