I sometimes wonder: “what if Rust bools were just another enum” and while not actually practical or anything imo, it’s a pretty fun thought exercise?

If/else statements are a really fun one here. We don’t want to have to write:

if let true = x {}

but instead we want to be able to write:

if x {}

Which I think we could do via a trait. But if we allowed that and made the trait stable, other enums could be “truthy” or “falsy”, which I’m not sure we’d want.

I told myself: today is the day I get to write code.

Folks, I did not write any code. I did write several planning documents documents. Can I get an “RIP”?

Success! Managed to get an HDMI out from my iPad!

The trick here was to use a Thunderbolt 4 cable, rather than any old USB-C cable.

Woo! ASAN support for #rust on #windows has now been merged in: https://github.com/rust-lang/rust/pull/118521

It uses the MSVC ASAN libraries, so you can safely link with C/C++ code built by MSVC with it's ASAN enabled.

Oh neat, someone wrote out an initial mapping of the WASI <-> WebIDL type systems! https://github.com/MendyBerger/webidl-wit#conversions-from-webidl-to-wit-types

This is going to be essential to expose Web APIs via WASM Components/WASI to guest languages. I'm excited!

Ohhhh — I just realized something. You know how labels can sometimes be visually noisy or not look good? But they are also often handy and useful!

What if… instead I just used transparent braille labels instead. Yes it requires learning to read braille. But on the flip side: for an occasional tag that has to sit in sight it could be really a really nice compromise!

I feel like the most important thing anyone can work on is their sense of self. Like, it’s so important to understand what it is you like. Which values you hold. How you want to be perceived. How you perceive yourself. All of it.

Most recently I’ve been working on developing a sense of… space? My partner spurred this on, but I’ve kind of gotten into it since. Where it’s okay to create a space which feels uniquely your own. And I think as a result our home feels like a real home. It’s our home.

Idle thoughts: why on earth do colleges and universities allow students to double major? It's just a trap for overachieving students. In the best case, they get a degree they don't benefit from in any way and miss out on a more well-rounded and less-stressful college experience. Ain't nobody actually needs two undergraduate degrees, and we do students a disservice by letting them think it's some kind of achievement.

OH HELL YES, TRAIN NEWS!!!! 🚂✨✨

An informal agreement has been reached that trains in the EU will have to have switched to the EU standard rail gage and signaling system by 2040! That means every. Single. Train. in the EU will work on every single track in the EU.

We’re getting one step closer to the dream of transcontinental sleeper trains! Next station: official sign off from EU member states, with votes happening in March and April.

The European Parliament lead on the file Dominique Riquet, a French lawmaker with the centrist Renew group, said with the new rules the EU is "creating the conditions for a shift towards more ecological transport modes, while stimulating the mobility of Europeans and the competitiveness of our economy". However, the centre-right EPP was less impressed, saying that the deal "falls short of our expectations and raises concerns about the real commitment of Member States to create a functioning European transport network". "National priorities jeopardise shared European goals, hindering an ambitious vision for rail," said the EPP's lead MEP on the file Barbara Thaler. "It goes against the EU's commitment to shift traffic from road to rail." The informal agreement will now need to be given the green light by member states and the European Parliament. A confirmation vote in the Parliament's transport committee is expected in March, with a plenary vote in April.

in an impressive failure of public transportation policy, it’s *about the same price and twice as fast to rent a car and drive to the airport, than to take public transportation + a shuttle (even if you live here)

Oh cool, I missed this: Clippy now has a large_futures opt-in lint. If you’re managing async codebases of a reasonable size, this may be worth trying out!

If done right it can help you identify where large state machines are being created, and possibly also identify places where you can use Box to peel off code that’s only occasionally run.

From what I’m seeing now, both government agencies and consumer advocacy orgs are beginning to encourage organizations to publish roadmaps of how they plan to become memory safe.

I have no inside information on this, so I’m just speculating: but it feels like a first step towards potential regulations? Not sure on what timeline or what scope (e.g. unsafe code needs to be written somewhere). But with memory safety issues being responsible for so many vulnerabilities, it feels like it might stick
