The uppercase A in Axium.

Very quickly skimmed Cargo.toml and main.rs.

What's with the title-case name?
The name proximity to axum is also not cool.
You should mention that this is built on top of axum in the project description.
How did you end up using both lazy_static and once_cell, when OnceLock has been stable since 1.70 and axum's MSRV is 1.75?
Why did you copy-paste min-sized-rust flags?
You can actually print like this:

println!("{proto}://{ip}:{port}");

instead of

println!("{0}://{1}:{2}", proto, ip, port);

and the positional indices are redundant anyway.

Since you're depending on tracing, you should actually use tracing::error instead of eprintln!("❌ ...").

Okay. I will stop here.

Migrating away from Rust [gamedev] in c/[email protected]

[–] [email protected] 8 points 1 month ago (4 children)

Reads okay for the most part. But I like how we see the same point about AI as a feature in some more serious real-life projects. There, we frame it as "Rust makes it harder for a 'contributor' to sneak in LLM-generated crap".

When I found out even Rust needed the clib, it was like seeing an iron-clad fortress only to look closer and see it was being held up by sticks, ducktape, and prayers. (github.com)

Every programming problem I have, when I track it down to it's source, seems to originate with C/C++. It wasn't till a few years ago that I realized how seriously everything I do somehow, some way, has C/C++ as a foundation. Basically every zero-day exploit in my cyber security class is because of something stupid in C/C++. And it goes well beyond security, the more I dive into C++ the more terrible stuff I find. When I found out even Rust needed the clib, it was like seeing an iron-clad fortress only to look closer and see it was being held up by sticks, ducktape, and prayers.

[Migration post] Can you please comment here if you see this post? That will allow us to have an idea of instances that are now federated with the community. in c/[email protected]

[–] [email protected] 1 points 1 month ago (1 children)

Its called fetching it.

No. I was specifically thinking of webfinger. That's Lemmy's (ActivityPub) way of checking if an id (user or community) exists or not. Then, an instance may "read" the remote community using its outbox (if requested), and a snapshot of that remote community would now exist in the local instance. That "snapshot" doesn't get updated unless another attempt is made to view the now known remote community, AND a certain period have passed (It was 24 hours the last time I looked). In that second time, a user may actually need to make a second request (refresh/retry) to see the updates, and may need to do that after a few seconds (depending on how busy/fast instances are).

If at least one user however subscribes to that remote community, then the remote instance live-federates all updates from that community to the subscribed user's local instance, and all these issues/complications go away.

You need subscribers from instances, not views. Without subscribers, an instance may have an outdated version of your community without updates. People may see your community because someone pinged* it recently, maybe via a search, and their instance grabbed your then outbox at that time.

Ideal Federation is achieved when you have 2+ subscribers from every instance federating with your community instance. One subscriber would be enough too, but people choose to nuke there accounts sometimes, and Lemmy has the option to really erase an account as if it never existed 😉

* or whatever Lemmy calls it, haven't looked in a while.

Cutting Down Rust Compile Times From 30 to 2 Minutes With One Thousand Crates in c/[email protected]

[–] [email protected] 8 points 2 months ago

make uses multiple processes for parallelism, or what the blog post (below) calls "interprocess parallelism". cargo/rustc has that and intraprocess parallelism for code generation (the backend) already. the plan is to have parallelism all the way starting from the frontend. This blog post explains it all:

Cool and all. But missing some experiments:

Along the same vein, too many open source projects don’t factor in non-“gnu/linux” environments from the start.

No one is entitled to anything from open-source projects.

I spent time making sure one of my public tools was cross platform once. This was pre-Rust (a C project), and before CI runners were commonly available.

I did manage it with relative ease, but Mac/mac (what is it now?) without hardware or VMware wasn't fun (or even supported/allowed). Windows was a space hog and it's a shit non-POSIX OS created by shits anyway, and Cygwin/MSYS wouldn't have cut it for multiple reasons including performance. The three major BSDs, however, were very easy (I had prior experience with FreeBSD, but it would have been easy in any case).

People seem to have forgotten that doing open-source was supposed to be fun first and for most. Or rather, the new generation seems to never have gotten that memo.

POSIX is usually where a good balance between fun and public service is struck. Whether Mac/mac is included depends on the project, AND the developers involved. With CLI tools, supporting Mac/mac is often easy, especially nowadays with CI runners. With GUIs, it's more complicated/situational.

Windows support should always be seen as charity, not an obligation, for all projects where it's not the primary target platform.

rustc_codegen_gcc: Progress Report #35 in c/[email protected]

[–] [email protected] 1 points 2 months ago

You need to call ./y.sh prepare again

Aha! Good to know. And yes, improved documents would be of great help.

Thanks again for working on this.

rustc_codegen_gcc: Progress Report #35 in c/[email protected]

[–] [email protected] 1 points 2 months ago (2 children)

But running

./y.sh prepare
./y.sh test --release

does work. That's what gave me the impression that clean all doesn't actually clean everything!

[–] [email protected] 1 points 2 months ago (4 children)

Yeah, apologies for not communicating the issue clearly.

cp config.example.toml config.toml
./y.sh prepare
./y.sh build --sysroot
./y.sh clean all
# above commands finish with success
# below, building succeeds, but it later fails with "error: failed to load source for dependency `rustc-std-workspace-alloc`
./y.sh test --release

And then trying to use the "release" build fails:

[OC] Rust tops a diverse list of implementation languages in projects getting NLnet grants, Python 2nd, C is alive, and C++ is half dead! (programming.dev)

Notes

Projects meaningfully sharing two programming languages get 0.5 a point each, even if the split is not exactly half-half.
Two projects are listed under "Multi/Misc/Other" which is opinionated, and some may disagree with.
Three points (5 projects) are assigned to "Unaccounted/Not Available". Two of the projects have no code at all (related to the grant, or otherwise). One project with no published code is (charitably) listed under "Python", however, since the author mentions Python+QT as the choice for implementation.

Koto: a simple and expressive programming language, usable as an extension language for Rust applications, or as a standalone scripting language (koto.dev)

submitted 5 months ago by [email protected] to c/[email protected]

7 comments fedilink

cross-posted from: https://programming.dev/post/23822190

I added this language to my watch list some time ago and forgot about it, until I got a notification about a new release (0.15) yesterday.

I'm someone who is familiar with system languages (C, Rust) and shell languages (Bash, Zsh, ..). But don't have much experience, at a proficient level, with any languages setting in between.

So I gave Koto's language guide a read, and found it to be very well-written, and the premise of the language in general to be interesting. I only got annoyed near the end when I got to @base, because I'm an anti-OOP diehard 😉

I hope this one well start to enjoy some adoption.
