I'm very pleased to announce that I'll be leading a session at this year's inaugural Rust NYC Unconf! Come by if you'd like to talk or hear about using Rust to underpin common, cross-language implementations of business functionality.

Sometimes rust traits really do let you cook up a really excellent abstraction for something. The good kind: specifically limiting in the way that using the abstraction forces you towards the correct pattern.

It's so funny that both the western left & western liberals are so determined to deny that our last & probably most consequential great joint triumph was in fact joint
"The combined might of American industry & the many peoples of the USSR broke the back of fascism for 80 years" is a good thing!!

Becoming more and more convinced that the _only_ correct model for shared mutability is one where you have to subscribe to updates.

Wound up in a use case where I could *really* use an undroppable type. Currently trying to force it like this:
fn use_undroppable<T: Undrop>(value: T) -> (Value, T::Token)
But it’s super super awkward ergonomically an unspeakably verbose in trait definitions

On the other hand if we see MN employers who SUPPORTED their employees, protected them from ICE, and defied the loathsome administration’s authoritarian efforts to get them fired, I would find a way to support those businesses. I would order one-day delivery of your hot dish RIGHT INTO MAH BELLY.
Seems as if this works — if employers start firing people for standing up for their neighbors and fellow humans — than a remedy is publicizing the identity of those employers.
Publishing the names of protesters and contacting their employers to have them fired for exercising their rights is a tactic straight out of the White Citizens Councils.

my neighbor told me deacons keep killing his polecats so I asked how many polecats he has and he said he just goes to the orchestrator and gets a new polecat afterwards so I said it sounds like he’s just feeding polecats to deacons and then his daughter started crying

Do I understand correctly that basically all of the horrible complexity around the try trait emerges from the unfortunate misfeature that `?` does a `From::from` with `Result::Err`?

I need people who don’t live in the Twin Cities to stop telling people not to join massive Signal groups right now. People are doing it. They’re going to keep doing it. Give them good advice about it.
The actually practical advice is don’t say anything to 1000 strangers you wouldn’t say in public

I do see at some level that this opinion might force me later to use complex numbers everywhere, but in practice I just find that subtraction comes up frequently and square roots uh do not
Like it’s to the point where I just don’t use unsigned types anymore if I’m expecting to do addition or subtraction on them, unless I’m forced to. I just use them as bit buckets.

I am a hardcore negative duration defender. Any time you have arithmetic you end up having negative numbers and it’s just too much hassle to keep them out.
me: programming is useful as a way to represent real-world phenomenons—
chrono: this duration is negative
me: mh?
chrono: you have a negative duration
me: I-
chrono: this duration is negative

not a weird question! I'm gonna answer it via a quote because others might also find this interesting.
@steveklabnik.com sort of weird question but have you seen anyone release code under the public domain and how do you do that properly b/c iirc that's a bit different than just slapping a MIT license on something

I know some have been a little unnerved at the aggressive following and noisemaking tactics of the observers. What they don’t realize is that it’s necessitated by what ICE is doing. You have seconds and you need as many eyes on them as possible, and as many people trying to get key info as possible.

Jesus Christ, we’ve returned to the days of the television news anchor telling you he smokes parliaments for their smooth flavour.
New: CBS News seems to be preparing a new segment called "Whiskey Fridays with Tony Dokoupil," per sources.
Some staff were only first made aware of it as they encountered CBS testing out set designs of a faux-stocked bar in the newsroom, featuring a large sponsor banner for Jack Daniels.
