My superpower is using rust-analyzer to color anything unsafe differently. Within an `unsafe` block, I can immediately see the specific operation that requires it and what operations are fine. It's *incredibly* useful.

The crates I maintain on crates.io don't have 2.8 billion downloads for nothing. My work is high quality, as anyone who has worked with me will attest to.
Unsure what I can do? I've spent some time optimizing the `time` crate. From knocking 10% off of hot paths to 10x speedups in edge cases, the gains are unquestionably real and impactful.
Interested? Send me a message here or send an email to what's on my profile: https://github.com/jhpratt
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.
Things I never expected to say: the `time` crate now contains an optimizing compiler. Like…full lexer, AST, IR, versioning, codgen, and now I'm working on an optimization pass.

@tiif@hachyderm.io I'm sure he was enthused haha. You have definitely earned the witch hat

@unsafe@m.webtoo.ls Parsing format descriptions! I used to do it in a single pass, straight into the final vec, but changed it to a mini-compiler a couple years ago. It made maintenance _much_ easier and allowed me to add new components quite easily. Now I'm adding some optimizations to the macro (but not runtime parser) to eliminate some not-uncommon situations that are a tad slower than necessary.

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!
When I booked places to stay on my trip to Europe, I didn't care to check if they had air conditioning...oh what a mistake that was
For those attending #RustWeek, I arrive in Utrecht early evening on the 20th. I'll be at the all-hands during the day Thu/Fri/Sat. If anyone wants to meet up, let me know! Feel free to pick my brain on anything :)

@thejpster @killercup some day! That's why I have the deranged crate. Throw in some nightly features and it can get very powerful.

I considered posting this in Spanish but thought that the vast majority of my followers would have no idea what I was talking about. Plus I don't think I have ever posted in Spanish (which I speak at a B1, borderline B2 level).

@argv_minus_one @Foodboxgourmet @pomarede My understanding is they'll be so far away the communication won't be distinguishable from noise in just a couple years anyway

@argv_minus_one @Foodboxgourmet @pomarede hm, looking it up, apparently there is enough power for another 10 years!

@GhostOnTheHalfShell@masto.ai @dystroy@mastodon.dystroy.org I can't speak for them, but I'm in a similar position. My code is used at so many places it's simply not possible to reach out in a (relatively) easy manner to most of them. They simply don't have a point of contact like that.

If your company is willing to give me a shot, I promise I'll abide by the puppy tax! Just in case you needed another reason 🙂🐶
Explaining to someone else that outside of the US and Canada (and others, probably), ground floor and first floor are not the same thing was not something I expected to do today…
It's amazing how bad #GitHub has been over the past few days. I simply can't load pages, even without going thru SPA stuff. Loading a pull request will hang indefinitely. It's ridiculous.
That isn't even to mention their app, which has been doing something similar for longer.

@chrisdenton@hachyderm.io sure, but sometimes it's nice to know the specific thing that's unsafe even in small blocks
