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.

GOTOphobia Considered Harmful (In C)
The state machine example is definitely a very fitting use of goto, but it reminds me of another thing that seems to have become a rare skill but is very useful: flowcharting. Besides making people comfortable with goto in general, it also helps visualise control flow in ways that a lot of programmers these days don't realise, and it's unfortunate that a lot of courses seem to have omitted its teaching.
Also worth reading is "GOTO Considered Harmful Considered Harmful": https://news.ycombinator.com/item?id=11056434
And here Microsoft provides us with lovely example of such ridiculous nesting.
That's a very memorable example, but ultimately the true cause of that monstrosity is a clearly stupid API design; this is the API for a file picker, the recommended replacement for an existing one that they wanted to deprecate. In the existing one, you fill in a structure and call a single function with a pointer to it. In its replacement, you need to call a dozen methods on an object, and check for "possible" errors on each call, even if probably 99% of them only do things like assign to a field in a now-opaque structure and can never produce an error. Then the example code must've been edited by someone with severe gotophobia. (Not all MS code is like that --- they have plenty of other example code that uses goto, e.g.: https://github.com/microsoft/Windows-driver-samples/blob/mai... )

Installing avssamp virtual camera driver in Windows 10
The source code for the sample can be found here. Check this code out to a local folder and use the included visual studio solution to open it up. You should be able to build this code as is; if it's telling you that you need spectre mitigated libraries to build it you can either acquire those via the visual studio installer or go to Project Properties > C++ > Code Generation > Spectre Mitigation and select disabled (I have it enabled so disabling it could cause issues, probably not though).

Question about Windows Drivers
Given that they're essential and worth about $1.8 million, then, it sounds like the proper solution would be to argue for the budget to engage a developer to write, test and sign a replacement driver. (Especially since the Intel 82930 USB test board is literally used by Microsoft as an archetypal example device in USB driver development documentation.)

Has anyone gotten Pulseaudio to work on macOS Catalina for mixing audio into the microphone?
Maybe corresponding Windows API? https://github.com/microsoft/Windows-driver-samples/tree/master/audio/simpleaudiosample and https://docs.microsoft.com/en-us/windows-hardware/drivers/audio/getting-started-with-wdm-audio-drivers.

A GPIO Driver in Rust
Well yes. But Linus is right on that one.
I wouldn't say Windows drivers were C++, more like "C with Classes" (and maybe a little bit C++)
Also, Windows drivers are usually much more convoluted than Linux drivers https://github.com/microsoft/Windows-driver-samples

Wayland vs. X – Overview
libei looks useful. But IDK why libei is necessary to run Barrier with Wayland?
For client systems, couldn't there just be a virtual /dev/inputXYZ that Barrier forwards events through
And for host systems, it looks like xev only logs input events when the window is focused.
Is xeyes still broken on Wayland, and how to fix it so that it would work with Barrier?
With Barrier, when the mouse cursor reaches a screen boundary, the keyboard and mouse input are then passed to a different X session on another box until the cursor again crosses a screen boundary rule.
Barrier is a fork of Synergy's open core: https://github.com/debauchee/barrier

KVM Switch for Gaming and WFH
I have a similar gaming/WFH setup (2 monitors at 1440p 144hz) and I’ve been using Barrier instead of a physical kvm, and it works really well. Not sure if you’re open to a software kvm but if you are, I’m happy to answer any questions about it if you have any.

Autoswap Keyboard Layouts based on Operating System
Have you tried Barrier? I casually used it to swap between my main rig and my MBP. Took a minute to get it setup but once I sorted it all out it worked pretty well. It has some settings and tweaks built in to address some of the layout issues you mentioned...

IT/programming multi-monitor setup? (coming from 6x old 21" square)
Sorry, probably not entirely on topic and can't answer anything reliable about the multimonitor stuff, but a tip regarding the 2 mice and 2 keyboards for the 2 different computers: use this: https://github.com/debauchee/barrier It's oss multi-os software that lets you use one mouse and keyboard (server) on several PCs (clients) easily over your LAN.
