On an Arduino there are libraries to drive sensors. On a Linux desktop the hardware is automatically configured and abstracted. But what about embedded Linux? What about a Raspberry Pi? This is where…

A deep dive into the three major versions of HTTP that dominate the web today and how they evolved to meet the needs of the modern internet.

TL;DR Certifications are not bad; chasing them is. A badge proves you reached the passing mark on one exam on one day. It does not prove you have run the service in production, and the terms attached…

AI didn't make software less valuable. It removed the disguise that building it was the hard part. Notes on supply and demand, where things may be moving.

A person is a seed and a few props. No .glb , no textures, no rig to import. Everything else falls out of that. Every game with a character creator ends up with the same pile of stuff. A base mesh, a…

这篇文章欠了缺氧好久。此游戏耗费笔者宝贵的六百七十六个小时青春。越想愈觉得设计精妙、难以改进。 妈的，这么牛逼，我操 游戏的目的（注意区别于异化后的娱乐。笔者本人极其厌恶在线游戏等以营利为主要目的的作品，本质为资本主义剥削用户注意力，和短视频等批判方式相同。）与传统艺术并无不一，本质都是使得观众/游玩者获得特定的情感体验。在传统艺术的基础上，游戏多了“交互性”这一工具，使得艺术表达边界获得极大的拓…

For a long time, visual SaaS apps have been the go-to solution for professional tooling. But with coding agents, this is changing – and the apps we build now need to work just as well for the agents…

I don't use Chrome, as I dislike Google's blatant disrespect for my privacy, so instead I use Ungoogled Chromium as my browser [1] . Because Ungoogled Chromium is a community-run project, they are…

We’re safe from ω...for now

Where I think AI takes science over the next decades, and why everything outside math has to be checked against nature.

I have an app in my head I'm tempted to 'vibe code'; the reason why I'm reticent might not be what you think. (But it might be that, too.)
