There's a man in the US who demolished part of his residence, leaving the ruins lying there. At the same time, he destroyed his beautiful garden by paving over it. Now in a few short days there will be brawls on his front lawn, all while people stand around and cheer.
You wouldn't find that acceptable, would you? Unfortunately that man is the fucking president.
I am available (immediately) for Rust work! Whether it is finding nontrivial performance gains, reviewing code for correctness and soundness, or writing implementations from scratch, I am a knowledgeable engineer with experience at companies large and small from various industries.
If your company would like to discuss setting something up, contact me via the email on my GitHub profile (https://github.com/jhpratt).
As an alternative, feel free to sponsor my open source work directly! I have recently improved performance significantly for the `time` crate, including a 3× gain in parsing format descriptions (on top of the gains actually parsing/formatting values). Without funding, this will necessarily slow down or stop at some point.

I accidentally blocked the domain rather than a specific user, so you no longer follow me. I unblocked the domain immediately, but I'm pretty sure that's not undone. Sorry!
I think the most *unique* part of #RustWeek was a scheduled meeting with TC39 (the JavaScript folks) regarding date and time handling. But it is such an expert-level and niche topic that it turned out to be a one-on-one.
Speaker Spotlight: Jacob Pratt, Senior Software Eng
Jacob maintains one of Rust's foundational time crates. On Sept 10, hear how it's done: API design, algorithms from scratch, security handling, and the quiet art of catching bugs early.
