I’m now team leader of the Rust Infrastructure team!
I’ll keep shipping, but I’ll also pay more attention to the load, health, and overall direction of the team.

I made a computer that shoots people with a gun. The frontier is moving too fast. The government must make it illegal to have this technology unless they pay my friends a bunch of money to investigate when their computer shoots people with a gun.

They fixed the `wsl ~` expansion 😭 It was a very good spacebar heating feature 🐛 Now you have to `wsl --cd '~'`. While you can alias this, it's no longer the same spacebar heater 😔😔😔

I was asked recently about the cost of running a #rustlang conference and why the ticket prices are what they are. We figured we can just publicly share the numbers for RustWeek, in the name of #transparency. :)

Godbolt's Compiler Explorer now supports build systems (like cargo). This is so cool!
I use Compiler Explorer quite a bit when playing with AArch32 stuff in Rust, to check I'm getting the kind of instructions I expected but I was limited to single files. Having cargo support is game changing.
