A standalone zero-dependency Lisp for Linux
> libc isn't really getting in the way here.
For the standard set of system calls, the libc is pretty great. For Linux-specific features, it could take years for glibc to gain support. Perhaps it's gotten better since then, perhaps it still takes years. I don't know.
Years ago I read about the tale of the getrandom system call and the quest to get glibc to support it:
https://lwn.net/Articles/711013/
A kernel hacker wrote in an email:
> maybe the kernel developers should support a libinux.a library that would allow us to bypass glibc when they are being non-helpful
That made a lot of sense to me. I took that concept and kind of ran with it. Started a liblinux project, essentially a libc with nothing but the thinnest possible system call wrappers. Researched quite a bit about glibc's attitude towards Linux to justify it:
https://github.com/matheusmoreira/liblinux#why
Eventually I discovered Linux was already doing the same thing with their own nolibc.h file which they were already using in their own tools. It was a single file back then, by now it's become a sprawling directory full of code:
https://github.com/torvalds/linux/tree/master/tools/include/...
Even asked Greg Kroah-Hartman on reddit about it once:
https://old.reddit.com/r/linux/comments/fx5e4v/im_greg_kroah...
Since the kernel was developing their own awesome headers, I decided to drop liblinux and start lone instead. :)

Nolibc: A minimal C-library replacement shipped with the kernel
It gives you access to 100% of Linux's system calls. It eliminates a lot of global state. It gets rid of a lot of legacy libc crap.
Years ago I wrote a fairly referenced rationale in my liblinux project:

Win32 Is the Only Stable ABI on Linux
> Now, do I think it would make total sense for syscall wrappers and NSS to be split into their own libs (or dbus interfaces maybe) with stable ABIs to enable other libc's, absolutely!
I worked on this a few years ago: liblinux.
https://github.com/matheusmoreira/liblinux
I'm not developing it anymore though because I found out the Linux kernel itself has a superior nolibc library:
https://github.com/torvalds/linux/tree/master/tools/include/...
It used to be a single header but it looks like they've recently organized it into a proper project!
I wonder if it will become some kind of official kernel library at some point. I asked Greg Kroah-Hartman about this and he mentioned there was once a klibc:
https://old.reddit.com/r/linux/comments/fx5e4v/im_greg_kroah...
> This is something the BSD's got absolutely right.
BSDs, every other operating system really, force us to use the bundled C libraries and the C ABI. I think Linux's approach is better. It has a language-agnostic system call binary interface: it's just a simple calling convention and the system call instruction.
The right place for system call support is the compiler. We should have system_call keywords that cause it to emit code in the aforementioned calling convention. With this single keyword, it's possible to do program literally anything on Linux. Wrappers for every specific system call should be part of every language's standard library with language-specific types and semantics.

Oasis: Small statically-linked Linux system
I'm not using this stuff professionally, it's just my own home lab's virtual machines with little services implemented as freestanding C programs. Not doing anything fancy right now, much of it was just to see if I could do it.
I've seen other people commenting here on HN saying they're using the same approach so it's defenitely not my invention.
I published some of my work in the form of a liblinux that I use to make system calls:

A Tutorial on Portable Makefiles
That's awesome. I didn't know about rwildcard until now. Is it part of GMSL? I searched for rwildcard on gmsl.sourceforge.io but didn't find it.
I think my function is needlessly complicated compared to rwildcard. Here's my code:
https://github.com/matheusmoreira/liblinux/blob/modular-buil...
https://github.com/matheusmoreira/liblinux/blob/modular-buil...
The file? and directory? functions were inspired by GMSL.
I wrote a general recursion function. It takes a function to apply to lists and a function to compute whether an element is a base case.
The recursive file system traversal function applies a directory globbing function to the list of paths and has file? as base case.
The find function filters out any items not matching a given predicate function. It was my intention to provide predicates like C_file? and header_file? but I stopped developing that project before that happened.
I think rwildcard is probably simpler and more efficient!

If it's got the Logitech unifying receiver, it won't work outta the box. You gotta download Solaar

Logitech M720 Triathlon - What do you think of it?
Now moving on to the Linux part. Do you use gnome/kde? Or some tiling DE? I use Solaar and it's lovely! M720 has a perfectly placed gestures button. I use it to move my windows to left/right monitors and switch between upper/lower desktop spaces. The gesture button works flawlessly when you set up solaar correctly.

Runit script for Solaar
I've been beating my head against the wall trying to figure out why this isn't working as I expect. I'm trying to make a user service to run solaar so that my logitech mouse's scroll wheel behaves like I want without having to open the app manually. The software itself provides a .desktop file for autostart, and I used this as a basis.

Silly problem but what are you guys doing for keyboard/mouse setup?
We don't officially support wireless keyboards or mice for infosec, environmental, and supportability reasons. But if we had to, the established Logitech Unifying and newer Logitech Bolt ecosystem allow for ready re-pairing of dongles with peripherals. Logitech Unifying is fully functional under Linux with solaar from your distro's repos. You have to be astute when buying, to always look for a picture of the dongle with the orange Unifying logo or the safety-yellow Bolt logo, however. If the logo isn't on the packaging or in the promo picture, I can assure you that you will not get a Unifying or Bolt dongle.
