A simplified model of Fil-C
I've seen lots of chatter about Fil-C recently, which pitches itself as a memory safe implementation of C/C++. You can read the gritty details of how this is achieved, but for people coming across it for the first time, I think there is value in showing a simplified version, as once you've understood the simplified…

Maybe comments should explain 'what' (2017)
People say “Comments should explain why, not what.” I feel like starting a flame war today so I’m going to argue that comments should explain ‘what’ too. Please don’t use this as justification to write bad code, okay? Okay. First of all, why shouldn’t comments explain ‘what’? If you need comments to explain what’s…

How to make Firefox builds 17% faster
In the previous post, I mentioned that buildcache has some unique properties compared to ccache and sccache. One of them is its Lua plugin system, which lets you write custom wrappers for programs that aren’t compilers in the traditional sense. With Bug 2027655 now merged, we can use this to cache Firefox’s WebIDL…

Girls just wanna have fast MPMC queues with bounded waiting
Disclaimer: An earlier version of this post claimed the structure is wait-free, this is incorrect. Being wait-free requires that failure or suspension of any thread can’t cause failure or suspension of another thread. This queue in fact does not fulfill that requirement. The main section which discusses the wait…

NixOS is making me less afraid
Something funny happened a little while ago: I read about FreshRSS, and it sounded nice, so I installed it on a server and started using it . That would not have happened a year ago, but then again, a year ago I didn’t have any NixOS servers.

Don't create .gitkeep files, use .gitignore instead (2023)
