Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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!

Video stops on furst frame, audio continues to play,seek works
I apologise for not following procedure. I am in the middle of building mpv 0.37 from source. Irrespective of the outcome I will document what I had to do in addition to the instructions on mpv.io and if the problem perststs, where it happens and where not with kernel version, mpv version taken from the screen, and the terminal output.

Use MPV. Partticularily shinchiro's builds. Extract the folder where you want its installation directory to be, if you decide to install it. Otherwise, just drag and drop files on top of its window or executable.

Ripgrep is faster than {grep, ag, Git grep, ucg, pt, sift}
Author of ripgrep here.
Like automatic encoding detection and transparently searching UTF-16?
Or simple ways for composing character classes, e.g., `[\pL&&\p{Greek}]` for all codepoints in the Greek script that are letters. Another favorite of mine is `\P{ascii}`, which will search for any codepoint that isn't in the ASCII subset.
Or more sophisticated filtering features that let you automatically respect things like gitignore rules.
Those are all things that ripgrep does that grep does not. So I do not favor this explanation personally.
ripgrep has just about all of the functionality that GNU grep does. I would say the two biggest missing pieces at this point are:
* POSIX locale support. (But this might be a feature[1].)
* Support for "basic" regexes or some equivalent that flips the escaping rules around. i.e., You need to write `\+` to match 1 or more things, where as `+` will just match `+ literally.
Otherwise, ripgrep has unfortunately grown just about as many flags as GNU grep.
