Population-based training of neural networks
Neural networks have shown great success in everything from playing Go and Atari games to image recognition and language translation. But often overlooked is that the success of a neural network at a particular application is often determined by a series of choices made at the start of the research, including what…

What Monoids teach us about software
Monoids are a pretty interesting concept in software development. Monoids are everywhere. Monoids are simple yet powerful. And Monoids have a lot to teach us about software, in particular about com…

The hard part in becoming a command line wizard
I've long been impressed by shell one-liners. They seem like magical incantations. Pipe a few terse commands together, et voilà! Out pops the solution to a problem that would seem to require pages of code. Are these one-liners real or mythology? To some extent, they're both. Below I'll give a famous real example. Then…

What makes developers productive?
Many ingredients go into developer productivity. Some are obvious and easy to measure (build times are an easy example to point to). But I think we tend to miss other important factors, perhaps because they are hard to directly measure. For example, no system collects a number that shows how well each developer…

Packed structs in Zig make bit/flag sets trivial
As we've been building Mach engine, we've been using a neat little pattern in Zig that enables writing flag sets more nicely in Zig than in other languages. Here's a brief explainer.

My tutorial and take on C++20 coroutines
Over the last 25 years, I’ve written a lot of event-driven code in C++. A typical example of event-driven code is registering a callback that gets invoked every time a socket has data to be read. Once you have read an entire message, possibly after many invocations, you parse the message and invoke another callback…

Yes, Claude Code can decompile itself. Here's the source code
These LLMs are shockingly good at deobfuscation, transpilation and structure to structure conversions. I discovered this back around Christmas where I asked an LLM to make me an Haskell audio library by transpiling a rust implementation. An “oh fuck” moment in timeOver the Christmas break I’ve been critically looking
