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.

Akalabeth: Porting from AppleSoft Basic to Gwbasic
Fun fact...Microsoft open sourced GW-BASIC under the MIT license a couple years ago...

Basic and the ROMs that changed the world (and then disappeared) (2022)
I'm way ahead of you :)
Unfortunately, rewriting it without reverse engineering makes it almost impossible to reach the same performance characteristics. These are essential to reproduce proper timing in several games.
Also, it may not be much code, but the floating point operations are quite a piece of art. See the GW-BASIC source code, which is somewhat similar [1].
I also rewrote most of the BASIC interpreter directly in Kotlin, omitting assembly, but obviously that runs into the same compatibility issues.
As far as I understand it, reverse engineering is not allowed without permission, although some people suggest that it is ok to get other software to run. Not sure whether that case would hold up for my entertainment value.

GPL-3.0 licensed BIOS for Intel 8088 based computers

Question regarding floating point
Hey! They use an emulation. You can implement this yourself but it's quite the undertaking if you also want trigonometry functions etc. There are libraries available but they can be hard to build on older compilers, search for floating point emulation c library to get some ideas. Depending on what you want to do however are you sure you need floating point? I thought so in the past but have reconsidered. Many times you can work something out by either scaling or smart fractions like 355/113 for pi etc. Regarding scaling, this is also how fixed point math works, certainly also of interest and maybe more then enough?

The File Filesystem
FFS predates FreeBSD and is in some capacity supported by all 3 major BSDs. I'm fairly confident that Linux actually supports it through the ufs driver ( https://github.com/torvalds/linux/tree/master/fs/ufs ); whether the use of different names in different places makes it better or worse is an exercise for the reader.

Linus Torvalds adds arbitrary tabs to kernel code
These are a bit easier to see what's going on:
https://github.com/torvalds/linux/commit/d5cf50dafc9dd5faa1e...
https://github.com/torvalds/linux/blob/d5cf50dafc9dd5faa1e61...
Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

PfSense Software Embraces Change: A Strategic Migration to the Linux Kernel
There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

Improvements to static analysis in GCC 14
> The original less-than check was deemed incorrect
It was only deemed incorrect because of an information leak. Not because it's a valid use-case for user space to copy smaller portions of *hwrpb into user space. https://github.com/torvalds/linux/commit/21c5977a836e399fc71...

TinyMCE (also) moving from MIT to GPL
Correct. And the combined work needs to carry the MIT license text and copyright attributions for the MIT software authors. With binary distribution it must also be overt, not hidden in some source code drop, but directly accompanying the binary.
Many people who talk about relicensing never credit the MIT developers or distribute the MIT license text. "Because it's GPL now."
I don't think that you believe that, but many developers do.
Some don't see the need for source code scans for Open Source compliance, because the license.txt says GPL, so it's GPL. Prime example is the Linux kernel. There is code under different licenses in there, but people don't even read https://github.com/torvalds/linux/blob/master/COPYING till the end ("In addition, other licenses may also apply.") and conclude it's simply GPL 2 and nothing else.
Also be aware that sublicensing is not the same as relicensing.

The Linux Kernel Prepares for Rust 1.77 Upgrade
So If we would only count code and not comments, it is only 9489 LoC Rust. Which would be about 0.03% and if we take all lines and not only LoC it would be around 0.05%

Proposed Windows NT sync driver brings big Wine/Proton performance improvements
AIUI fsync is built on futex_waitv which has been upstreamed. So this has to be more than that.
