This is a very "US english" vs "EU english" thing. In US English, "IT" almost always means tech support/networking, where software/tech/engineering is somewhat different.

In the EU, IT tends to cover a much broader "tech" scope.

I highly recommend listening to/watching www.youtube.com/watch?v=ct10... before, if you want the good background info (no spoilers for tomorrow's recording, promise!)

a slide that says "type erasure in rust in ergot"

a slide that says "rust is a strongly typed language"

IMO: it's fair game.

lol I spent like half a day debugging something that made NO sense, just a string of confounding evidence, then I woke up at like 4:30am with my brain just handing me an "oh this is what is happening" answer.

what the hell brain, I need to go back to sleep, but thanks, that actually helps a lot.

Yeah, this totally tripped me up too

The survey had 7310 completions in 2024. For the respondents who "consider themselves a member of an underrepresented or marginalized group in technology", there were 1110 respondents, 54% LGB(non-hetero), and 36% Trans, but that's 8.2% and 5.5% of the total pop

I have availability for Rust consulting or coaching. More details soon, and yep my website needs updating. But if you're considering adopting Rust, want your team to use Rust more effectively, or need a drop-in staff engineer, get in touch!

"An actual community-oriented/governed/powered co-operative rolls in to do a full takeover of the RubyGems ecosystem after RubyGems/Ruby Central themselves got taken over by the fash" was not on my bingo cards for 2025 either but here we are and I am here for it: gem.coop

If you haven't listened to the two Protomen albums before, I dunno how to describe how much you should give them a listen. Like, it's nominally a rock opera about Megaman lore, but (without spoiling anything) it's such an odd flavor of a hero's journey that hits pretty hard (both albums!)

I feel like if you wanted One Cool Trick to find the Real Cool Code in Rust, you could just search for `UnsafeCell>`, e.g. grep.app/search?q=Uns...

If you have the .cargo/config.toml at the workspace level, and you're IN the crate folder, because cargo looks recursively upwards, it will still work I think?

Honestly, I'm working from memory here, so I'd trust your repro over my posts :)

James Munns @jamesmunns.com · 3d

I may have been misremembering based on the fact that it takes the invocation path (NOT the workspace base), so if you have the .cargo/config.toml in the crate folder, but run it from the workspace folder, it doesn't "find" the config.

BUT:

`.cargo/config.toml` handling, and honestly workspaces in general, are full of a lot of Fun and Surprising Gotchas, unfortunately. Embedded has been leaning more on build-rs scripts recently to set linker args than .cargo/config.toml for reasons like this, and I tell people to avoid workspaces

James Munns @jamesmunns.com · 3d

Got some more weird goofy cases, not sure if these count as semver relevant tho: bsky.app/profile/jame...

James Munns @jamesmunns.com · 16d

cargo will look recursively up from the current directory for `.cargo/config.toml` files, which is great if you want to set some kind of setting globally, less so if that setting happens to override an embedded setting you're making locally.

James Munns @jamesmunns.com · 3d

Is that differences in `.cargo/config.toml` detection? I can't remember if that uses the invocation pwd or the manifest directory.

I wish something like `rg` was "binary aware"

As in I want to grep to see if a symbol is in in the import or export tables of a binary and what not, that would be nice.

Extensions/plugins would be very fun. Something based on magic strings or extensions.
