Reflections on Rusting Trust - In Pursuit of Laziness
The Rust compiler is written in Rust. This is overall a pretty common practice in compiler development. This usually means that the process of …

One of the biggest limitations of markdown is the lack of extensibility. Nimble, a competing syntax, has macros!

PHP's unbalanced " handling is not very smart: https://phpsadness.com/sad/44 though the general problem of good errors on invalid syntax is hard.

I felt really smart building a debug buffer for racer.el. I've just realised this is exactly what $ does in magit too. New ideas are hard!

GUI automation is a hard problem. I'm impressed by Hammerspoon (OS X) and its nontrivial examples in the basic docs:

A fascinating deep dive into the murky world of exported symbols in ELF files:
What is an ELF Export?
An online electronic journal repository for various projects, topics, tutorials, and other such texts, usually dealing with programming languages, reverse engineering, CS theory, object/binary analysis, formal methods, formal logic, and maybe, sometimes, even philosophy

The rustc team is exploring a new backend for faster debug builds, originally written for a JS engine!
Possible alternative compiler backend: Cretonne
Possible alternative compiler backend: Cretonne
Hi everyone, So I’ve been having some interesting conversations with @sunfishcode, and I wanted to talk about an idea that he floated to me and try to get some feedback. The idea is to add an alternate backend to LLVM based on Cretonne. Cretonne is a compiler IR, similar to LLVM, being implemented (in Rust!) for use with WASM. It is intended for use in SpiderMonkey, Mozilla’s JS engine. The idea is that if you load WASM, it will be converted to Cretonne and optimized – similarly, when executing...

I don't get stickers in message apps. Emoji are simpler (more broadly applicable) and don't use tons of screen real estate. Do you use them?

Incredible work making rustc faster: https://blog.mozilla.org/nnethercote/2016/11/23/how-to-speed-up-the-rust-compiler-some-more/ (even the core team overuse .clone() sometimes—comforting for the rest of us!)

Emacs tip of the day: you can press F3 when defining a macro. This inserts an auto incrementing counter -- great for building numeric lists!
