Over the last several months I have been tracking AI guys trying to create vibe coded clones of popular apps, especially Adobe’s apps which have always been the most pirated apps since the 90s. There are now about a dozen vibe coded attempts to clone Photoshop and some other Adobe apps, not incl

Type-safe HTML templating in Zig
I’ve done a lot of web development over the years. I started around the year 2000, just after PHP 3.0 was released and started taking over the web world. I’ve used all kinds of approaches for generating HTML: raw PHP, string concatenation in Python, Smarty templates in PHP, Template Toolkit in Perl, and Jinja/Django…

I'm sorry, but you still have to think
DHH, the creator of the Ruby on Rails framework, decided to rewrite Campfire Once from Ruby on Rails to Rust. Or rather ask a clanker to do it for him, as he can't stand reading or writing the Rust code himself. After that he added rewrites in other languages , like Elixir and Go.

The tilde in your PATH may not be your HOME

I paid people to try and follow my README
Developers suck at writing documentation. We like to say RTFM but often there ain't no FM to R. At best we have a half-arsed collection of notes, some obsolete tips, and a link to a desolate forum full of people asking the same questions again and again. That's no way to treat our users. I naïvely believe there's a…

500B tokens later: Letting AI agents decompile a first-person shooter
During the last 3 months, I spent some of my time and tokens decompiling a popular first-person shooter. The goal was not to reach a simple proof-of-concept state. Instead, we really wanted an accurate, stable and feature-complete recreation of the game. The avid reader of my blog might have noticed that I had…

Consider your everyday language model, to get typed output from it (JSON), you may use Structured Output to constrain the output to guaranteed valid JSON. While model prefills the input in one pass,

Unikernels were hard. key word: were
Justin Cormack, who worked on MirageOS back in the day, called me at the pub to talk about why unikernels are coming back. The friction that made them hard is gone, the operating system is design debt, and if you care about security you should seriously consider them.

I would like the value of my home to rise, while my property taxes fall
Many of us are inconsistent in our economic desires. I would like the price of my home to rise, because it increases my wealth, but I would also like the prices of all other homes to fall, so that I could sell my house and buy an even nicer house. Also, I would like to
