a really cool post explaining design of gc-arena

Lix is an independent variant of the Nix package manager, developed by a team of open-source volunteers, and maintained by and for a passionate community of users.

I kind of assumed that Lix is a purely political fork, but they seem to write actual code, so that’s nice. Changelog promises faster evaluation, better errors and REPL improvements.

The generic dilemma is this: do you want slow programmers, slow compilers and bloated binaries, or slow execution times?

No generics / monomorphization / dynamic dispatch

Looks really cool. I wonder what’s inside.

A nice post about SIMD algorithms using Rust’s portable SIMD as an example.

A very nice paper about fuzzing Rust compiler by generating custom MIR. Found some bugs in both rustc and LLVM, but notably not in Cranelift.

This blog post is one of those things that just blew up. From a tiny observation at work about odd behaviors of spinlocks I spent months trying to find good benchmarks, (still not entirely successful) writing my own spinlocks, mutexes and condition variables and even contributing a patch to the Linux kernel. The main thing I’ll try to answer is to give some more informed guidance on the endless discussion of mutex vs spinlock. Besides that I found that most mutex implementations are really good, that most spinlock implementations are pretty bad, and that the Linux scheduler is OK but far from ideal. The most popular replacement, the MuQSS scheduler has other problems instead. (the Windows scheduler is pretty good though)

The site contains all the lectures, project materials and tools necessary for building a general-purpose computer system and a modern software hierarchy from the ground up.

Dungeons and Dragons, but about philosophy.

Push key blocks into their slots to gain control of the qwert. Regain Ctrl (and possible other keys) to get to the get through to the end. There are fourteen levels total. Can you get through them all?

It turns out that finite state machines are useful for things other than expressing computation. Finite state machines can also be used to compactly represent ordered sets or maps of strings that can be searched very quickly.

A lot about sockets, syscalls and bits

WebKit's FTL JIT now uses a new backend on OS X — the Bare Bones Backend, or B3 for short, replaces LLVM as the low-level optimizer.

TIS-100 is an open-ended programming game by Zachtronics, the creators of SpaceChem and Infinifactory, in which you rewrite corrupted code segments to repair the TIS-100 and unlock its secrets. It’s the assembly language programming game you never asked for!

A recording debugger promising to “reduce the debugging time dramatically”.
