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.

Design, Implementation and Evaluation of the SeL4 Device Driver Framework [pdf]
seL4 foundation members[0] are using it.
There's Genode[1], which supports it among other kernels, offering a fancy desktop environment.
However, efforts like this driver framework do help. There's also Makatea[2], an effort to implement a stronger Qubes-like system based on seL4.

eBPF Documentary
> While this is true from a certain perspective, machine code creates a system which must grand access to many things to become usable. A shared file system is a good example of this. Some software could easily echo a line into you .profile that tries to launch a key-logger, and this works in many cases.
That's common, but it's certainly not a requirement to run native code. For example, we've done a pretty good job at retroactively fixing that while preserving backwards compatibility with containers (I can, and have run normal official Firefox binaries inside a docker container with zero access to my real home directory) or sandboxes like flatpak (bubblewrap). If you want to run real native binaries but don't have to preserve backwards compatibility, then it gets easy; genode ( https://genode.org/ ) does a lovely job of truly practicing only giving programs what access you want to give them.
> The expectation of software existing as opaque files creates a huge amount of work for the OS in verifying the exact behaviour of the software as it runs (and in ways which can often be circumvented), rather than a source-based approach in which malware is never allowed to touch the processor.
I think you're overoptimistic regarding what you can do with the source code short of manual (human) auditing. I mean, sure there are things you can scan for to try and catch bad behavior, but in the case of actual malice I wouldn't trust automatic code analysis to protect me.
>> I'm typing this on a nice comfy GNU/Linux box where the only blobs are some firmware
> So you suffer the worst of both worlds then. You've had to download and compile the source yourself, but as the software is designed around being distributed as blobs, so you enjoy none of the benefits that might come from source distribution.
I have no idea why you think either of those things? Depending on the distro I certainly can compile from source on my own box (ex. Gentoo, NixOS), but I can also use precompiled binaries (ex. Debian, NixOS) while still having it be trivial to go find the exact source that went in to the binary package I downloaded (this has gotten even stronger with Reproducibility efforts meaning that I can even verify the exact source and build config that created a specific binary). The actual application software and OS are available as Open Source code that can be audited, with binaries available as a convenience, and the only remaining blobs (unwelcome but impractical to fix so far) are firmware blobs with relatively constrained roles (and on machines with an IOMMU we can even enforce what access they have, which is a nice mitigation).

Showstopper: Nobody is writing new operating systems any more
Genode[1] is slowly approaching the point at which I can use it as a daily driver. I hope it makes it before Windows 10 goes away. It will be nice to never have to work about viruses, or spyware, etc., any more. It'll be like a trip back to the free spirited days of DOS and write protected floppy boot disks.

Ask HN: How to get into OS/systems programming in 2023?
I'd dig into genode[1], which is a capability based operating system. You'll likely see an upsurge in interest in capability based systems in the next decade.

Linux Kernel Ksmbd Use-After-Free Remote Code Execution Vulnerability
Yet another exploit that just wouldn't work on a well-designed system, such as Genode[0].

the maddening truth of using Qubes
Have you looked at Genode? I don't think it's usable day-to-day yet but the concepts seem interesting.
- The Helios Microkernel: Written in Hare
- We've started a RISC-V64 Microkernel OS Project called "Generisc". We're gonna redo eveything an OS is with the "end" goal of a fully fledged running web-browser. Anybody wanna come aboard. Support and ideas is enough. No need for coding if you don't have time, just interest and feedback is good

Anyone wanna join me in changing out the Linux kernel with seL4? Not running LFS inside a seL4 hypervisor, but actually a native seL4 OS.
Maybe you should go into details a bit more what you are planning and why. There are (and have been) several approaches here. The most prominent might be Genode (https://www.reddit.com/r/genode, https://genode.org) and joining forces there might be a better approach than starting another project that will get lost in the details and complexity eventually.

Flathub just hit 1 billion total downloads
And not only that, the idea of portals is, IMO, misguided. See this view/bugreport when a flatseal user understands that even though they restricted permissions to access a certain area, the flatpak, itself, can ask to open files there and if OK'd that will be allowed. Their expectation is that with the overrides say "no access" it means "no access even if the flatpak asks very nicely". https://github.com/tchx84/Flatseal/issues/196

Mount a drive correctly in opensuse
Since you installed the programme via Flatpak, you should simply lack the necessary rights (https://docs.flatpak.org/en/latest/sandbox-permissions.html). You can extend the rights quite easily with https://github.com/tchx84/flatseal.

Where to file bug reports about "portals" ?
Yes, filed https://github.com/tchx84/Flatseal/issues/196 a while ago, got no joy.

Flatpak or tarball?
One design feature than can turn into an issue in some scenarios (usually dev tools) is the permissions of a flatpak. In case I need to tweak things, I use Flatseal. I know you can manually do this from the command line but I don’t change permissions that often so I don’t bother learning how to do that.

So Ive bit the bullet.. and bought a steam deck and have a few questions
https://github.com/tchx84/Flatseal (Also on Discover. For security reasons, the Discover store installs apps as sandboxed "flatpak" apps. This one is used to view what each up can do and change the permissions of apps. May be required if the sandboxing breaks something, though usually not required.)

How secure is Steam's sandbox in terms of reading contents in $HOME ?
I believe it does. As an example if I try running Godot from the Steam flatpak, it won't be able to see any of the contents of my ~/Projects folder unless I explicitly allow the steam flatpak access to that directory that via flatpak's CLI options or using Flatseal
