The entirely bit from the title was unfortunately auto-removed, but that's the key to the article's removal of libc.

brundolf5• 5 years ago

Without that word it sounds like it’s going to be a satire piece

I wish HN would chill out with the auto-editorializing

lmm• 5 years ago

I wish HN would remove the user-submitted title box, since it just encourages you to put your heart and soul into something that then gets overwritten by the mods anyway.

boulos3• 5 years ago

To be clear, I find the automatic edits to usually be useful. I left my comment to explain why I flagged the article (assuming 'dang looks at flagged posts and then has to wonder "Why is this flagged?").

Manual editorialising, too. (cf. correcting an error)

Recent example: https://news.ycombinator.com/item?id=28365163

As a joke I was thinking about making a web page that automatically updates its <title> tag to match whatever title HN chooses for its corresponding thread on the HN front page. :)

“I wish HN would chill out with the auto-editorializing”

Feel free to send an e-mail to 'dang and bring it up. (The e-mail address is linked at the bottom of this page.) He’s very nice and approachable.

chrismorgan• 5 years ago

FYI: the original poster can immediately after submission edit it and fix the title, and HN will leave it alone the second time.

brundolf5• 5 years ago

I think people often don't notice and then click away and go about their business. Nobody expects content they've just submitted to get silently changed under their nose.

mlindner• 5 years ago

Is there a way to ping dang so that he comes and fixes it? I wasn't aware HN did crazy shitty crap like this.

pronoiac• 5 years ago

The "contact" link in the footer points to the mods' email address. I've dropped a line.

isatty• 5 years ago

I thought this was a way to get literally anything to the top of HN - add as much rust as possible.

dang3• 5 years ago

Sorry! Fixed entirely.

I wonder if this can, in the future, provide yet another alternative to building binaries with statically linked musl libc. People criticise doing that, often deservedly so, but having had to build stuff inside containers with deliberately old libc just to get the binary to run on another, older system, I find joy in having a binary that I know to run in "every $HW_ARCH Linux userland". (Of course, even then, calling newer Linux syscalls brings upon some version limitations...)

BiteCode_dev2• 5 years ago

I wish to compile python from source in a way that will work in every $HW_ARCH Linux userland.

What are your advices?

What does your setup look like?

I'm really inexperienced with compiling software, but I'm playing with the idea of automating the creation of stand alone python distributions every time one is release to have a repo of it.

It looks full of gotchas though, espacially when you need to deal with ssl and tkinter.

kkirsche• 5 years ago

I don’t know it’s current status but either PyOxidizer or Nuitka are the two Python compilers I’d look to for that. It is full of trade offs, but to an extent that’s many dynamic languages like Python (said as a Python developer)

GoblinSlayer• 5 years ago

You can just extract that old libc.a and link against it. It's one file.

fnord77• 5 years ago

so this would allow binaries that would run on both alpine and glibc linuxes?

timClicks• 5 years ago

This is already possible, by statically linking musl. But the build process is probably simpler by using a pure Rust alternative.

vlovich123• 5 years ago

What happens if such a binary links in a C library? Won’t the missing init be a problem?

kzrdude• 5 years ago

If you rewrite the libc functions, maybe something could be offered like actually thread safe and safe environment variables. Or maybe that doesn't matter if no C libs are being linked in?

alakep• 5 years ago

This is the most hacker news article I’ve ever seen

Zababa• 5 years ago

I like seeing how the Rust community is becoming more mature. Learning to live with and accept existing code was really hard for me when I started programming.

Flow• 5 years ago

You learn over time to encapsulate and insulate to avoid other's crap code to infect your code-poems.

Less jokingly, programming has so many pain points that you learn to avoid. Simple things like reformatting a file, while a simple thing and seemingly necessary, can later end up being transformed into some of the less enjoyable mergings you have done.

Like a binary butterfly effect.

newpavlov• 5 years ago

I really hope that we will get a libc-free Linux target. Mustang/rsix looks like a great step in this direction, similarly to steed (https://github.com/japaric/steed) before it. But I think that ideally it should be done properly in Rust proper, not in outside projects. Here a relevant issue, but there is not much progress on it: https://github.com/rust-lang/rfcs/issues/2610

sunfish• 5 years ago

If there's community interest, there is a possible path where Mustang matures to the point where it makes sense to talk about how to incrementally migrate the parts that make sense into Rust proper.

jeffrallen• 5 years ago

Yay. This is something that, as a Go programmer, turned me off of Rust. We need to build a new world on new foundations without the risks of libc.

pjmlp• 5 years ago

Despite my critics of Go, one thing I really appreciate is the Go toolchain, and the decision to bootstrap the language.

With Go the usual "my compiler compiles your language" is out of the discussion table.

chakkepolja• 5 years ago

For me, its cross compilation being as easy as compiling with environment variable.

steveklabnik• 5 years ago

The problem is, on most platforms, that is literally impossible. Go has had to roll this back on many of them due to it. Linux making this possible is actually an outlier here, not the norm.

floxy• 5 years ago

Any updates to the rust-in-the-linux-kernel project?
