For posterity's sake, "Not thrilled to be spending another 4+ years thinking about your old pinned tweet" is a sentence said to me today

A post on june 25, 2015, from me on twitter:

For posterity's sake, "I hope you don't end up getting killed by nazis" is a sentence said to me today

A follow up: While people are digging through my twitter history, hopefully that's a tweet people remember in the future.

standards folks!

if you are in to this sort of thing, we now have an IETF mailing list to discuss AT protocol bits.

mailman3.ietf.org/mailman3/lis...

if you want to jump in, I recommend setting up an overall IETF datatracker account and reviewing IETF IP policies ("note well") first

allow dead code: "don't throw a warning if this code is not used"

expect unused: "don't throw a warning if this code is not used. please do throw a warning if this code is used."

Interesting. I haven't worked on much Rust lately so forgive me if this is a dumb question, but what's the difference?

Steve Klabnik @steveklabnik.com · 5h

decided to add it in a thread, great point thanks :)

Steve Klabnik @steveklabnik.com · 5h

for code that you're not using yet, but plan on it in the future, expect unused will help let you remember to remove the attribute once you do use it. allow dead code will not, you have to remove it, check, and see if it's still needed or not

If I had to pick a second great core value, it was the one going around recently:

You can just do things.

I'd put both of those to paper because, man, they're great.

Want to remark on a sentiment I've heard from the AT dev community ‒ in specific words, even, from @bmann.ca, @knowtheory.net, and @rude1.blacksky.team, which I'll likely botch here:

Lead with joy, not fear.

I think that belief shows up a lot, and it's really affected me for the better!

Anyway if you’re happy with git you should use it, for me personally, I was quite happy with git, but am more happy with jj. Always happy to answer questions if you have any.

It’s not limited to git; Google uses it with their monorepo, for example. Git is just the open source backend everyone uses because we all use git :)
