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.

My privacy journey -thanks to this and r/privacy sub AND how can I make it better
That's somewhat telling and can be used to "track" you, consider reading on non-Reddit privsec learning resources like Privacy Guides itself which you already know, PrivSec.Dev, madaidan's Insecurities and the like.

super secure phone with vpn
Considering the offer is legitimate (something I won't comment on), you shouldn't do most of these things, in my opinion. Don't mess with what'll be other people's phones. Sell them Pixels pre-installed with GrapheneOS and print papers with Auditor attestation instructions and maybe a few QR codes directing them to relevant documentation and privsec learning resources, such as the GrapheneOS documentation first and foremost, Privacy Guides, madaidan's Insecurities, PrivSec.dev, Seirdy's Home, Wonderfall's Lab, etc...

Ask HN: How do you trust that your personal machine is not compromised?
For some excellent advice on security and privacy based on thoroughly researched technical concerns rather than speculation or blind trust in your corporation of choice, see here: https://madaidans-insecurities.github.io/

Thanks to flatpak you can install the most recent software on an old distro. Or you can't
Be careful, you made madaidans-insecurities angry

Looking for Guidance on Hardening Fedora
Do read the materials posted by Mane25, Kirakuni, --Fernando if time allows. https://madaidans-insecurities.github.io is another gold mine of information and references if you feel like going extra mile.

Really considering switching to Bromite
Is it an article about madaidan ?

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).

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.

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

Why we're migrating (many of) our servers from Linux to FreeBSD
I said built-in, you seem to have missed that part. SELinux is not built-in(though it is for certain distributions of Linux).
Security is hard to define, let alone prove. Everyone has a very different definition of security. So first one has to ask, secure from what?
I imagine most of the reason around BSD not on the official list(s) is because it's not as popular. I mean GenodeOS[0] is arguably one of the most secure OS's around these days, but I doubt you can find any public Govt support(by any govt) for running it in production today.
Going back to my original comment, security is complicated, and there is no "secure", but hopefully for a given set of security threats, there is a "secure enough".
The same exists in physical security. Our home door locks are notoriously not secure, but they are generally secure enough for most home needs. But your average home door lock would obviously be idiotic as protection for Fort Knox's gold deposit door.
Comparing BSD to Linux security is complicated, but for most high value targets, the answer probably is, run more than one OS. Root DNS servers and other highly critical internet infrastructure all do this as a matter of common practice.
