@npub1rky…0xq2 Is there a way to not get mentions duplicated in the notifications tab? It feels redundant to have them show up in both places. Thanks!

@npub1eqg…fncn I have explicitly avoided diving into that part of Rust because the naming just doesn’t resonate with me. I’ll have to eventually, but thus far I’ve been able to avoid it.

@npub1jne…qvla Yeah, it is indeed quite loud. One advantage of this system is that if Polymaker releases an updated dryer we would only change that and keep the dry boxes.

Hey #rustlang people, is anyone aware of a #rocket (0.5) fairing or similar that enables converting SCSS into CSS on the fly? Or should I just do that as part of my build.rs or even Makefile?

@npub16mt…pnwy Why would marking it as a remix of the original HSW require a more open license? There’s no SA requirement on the original HSW so making it ND is fine I believe?

@npub1hg2…k372 and no tests were run, so the CI pipeline still failed after you pushed.

@npub17pq…49p0 How is that even possible!!?!

@npub1zaw…tdg8 Very cool, I’m just surprised at the restrictive license and that it’s a purpose-made account. Never seen that before.

@npub1eqg…fncn @npub1rqe…g8a8 Or just write the content in vim and then copy paste the content at the end in Word?
It’s much better practice to only do formatting at the end, after the content has been finalised, anyway.
Paste content, customise styles to match submission guidelines, apply styles to paragraphs, and Robert is your father’s brother.

@npub129g…4kwg I mean, that’s a terrible practice and wouldn’t pass CI in many projects. Don’t you also incur sometimes dramatic performance penalties by try/catching too much in some languages?
I’m just saying that while “hidden exceptions” are a problem, solid documentation usually is enough in this case.
I’d rather we don’t embark into unabashed zealotism, bashing all other than our own, as that’s not a good way to build a solid foundation.

@npub129g…4kwg You were afraid of data races in Python? Why did exceptions instil fear?

This is a fantastic article for many #Rust developers: https://mmapped.blog/posts/12-rust-error-handling.html

@npub129g…4kwg Ah, sorry for not being clear, I thought it was obvious while reading your code. I'd love to give a more detailed answer but codeberg is down again, so it'll have to wait '-_-

@npub1p9k…865w I see. Interesting. Can’t say I’m quite ready to go down the rabbit hole of making my own keyboard. Feel free to shout if you run into problems! And if you hand solder: leaded and flux core really is easier to work with.

@npub1hg2…k372 Could you elaborate as to why you believe this is an issue in its current state?

2023-10-11 07:59:02

@npub129g…4kwg @npub1nqp…w9sy @npub1qcm…8c4r It also depends what you’re benchmarking. Rust/Go/C will blow Node/Python/Ruby/Java out of the water when it comes to startup cost (process start time), but a tight inner loop in a warm JVM can give C a run for its money.

@npub1nqp…w9sy @npub1qcm…8c4r Golang is also the only garbage collected language out of all three. I haven’t looked at the benchmark, but that alone can give a serious slow down.
But just to clarify something: it’s not because something gets compiled down to machine code that it is inherently fast (or faster). JIT can perform miracles, and depending on the workload, cache-friendliness can have a dramatic effect.
A good Python program can outperform a bad C one, etc.

@npub16dc…7haa Is there a specific purpose you have a colour filter in addition to the light? I was under the impression that you needed one or the other, but this may be a mistake on my part?

@npub129g…4kwg I’m an avid Rust evangelist, and I use a lot of Rust in embedded dev, but this is a dumb hot take.
Programming languages are tools. There are tools for different jobs. In Rust, you could have an unwrap which panics instead of a nullptr deref in C. Both are a skill or tooling or testing methodology issue.
Please don’t taint Rust with this mindless drivel. Be better than this.

@npub1dn4…cue6 The “endlessly tweaking your config” meme about vim/neovim is starting to be about as annoying as the “can’t exit” one. Some people like to hop from editor to editor, others like to try every plugin under the sun, and some people just have a solid config that works, and just get stuff done.
I’d wager the last one is just a silent majority.
I think I’ve spent 2 hours on my config in the last decade, when I moved to neovim.
