The implant has been life changing. Now I just go in for annual cleaning and am always told to floss regularly. Even here in Germany the dentists can have incentives to give you bad advice, but seems like the US is much worse.

Learning Lock-Free Data Structures:

Mostly me exploring how to build a Treiber Stack (first in Go, then in C++) -> Figuring out ABA and Use-After-Free in the C++ implementation, and then touching a bit of Hazard Pointers, and ending with a benchmark comparison b/w a mutex and a lock-free version of the stack.

LLMs are a great tool at teaching and explaining. I don't use it to generate code, but it takes away the pain of searching and setting up dependencies, tools, etc. So I can focus only on the concepts and then do the testing.

It is not perfect, but I learned something that I did not know thanks to these techniques. And that too without reading dense and obscure books. I love it.

Why are we so eager to dismiss the very personal experiences of Andrew - someone who envisioned and developed Zig from the ground up? It is entirely within the realm of possibility that what he describes here did transpire. He had bad experiences with one of the more popular projects within the ecosystem - something that he hoped would become successful but the incentives were clearly misaligned.

When in doubt - look at the incentives. And the incentives here are fairly obvious. On one hand we have an open source project that is focused on quality and craftsmanship, and on the other hand we have the world's biggest AI company.

I am not anti-AI. But things like taste and quality matter. And I trust the creator of Zig more than the creator of Bun when it comes to said taste.
