yeah lol uarts aren't going anywhere, ever, although they're generally 3.3v these days, not 12v control lines generally don't see much use either

I like the cables, they are nice, but RS232 is also convenient at times. I just translated a massive project with 28 sub-projects from GNU Autotools to Meson. Meson is good if anybody is wondering (they weren't lol). Meson is probably the best make system of all the 3 major Linux ones (Autotools/Cmake/Meson).

As a result, we now have the shim loader which is signed by Microsoft and can chainload into signed Linux distributions using any user key mjg was the one who brought the attention of the press to Secure Boot where lots of them made insane and false claims about how Microsoft was pushing it as anticompetitive behavior.

Secure Boot is good secure boot is security theater and kernel lockdown is the most goddamn stupid poo poo. the barrier between user mode and kernel mode is never going to protect you against malicious code outside of very specific scenarios like seccomp. or are you telling me i am hallucinating the existence of all those myriad android jailbreaks. if your server gets owned then you re-establish a root of trust by reinstalling it from trusted media. the main thing you care about there is that your attacker cannot flash a system firmware image that lacks a valid vendor signature, or flash a system firmware image that predates the current one. even if the user-kernel boundary was invulnerable, which it is extremely not even if you do come up with a few dozen possible attack vectors off the top of your head one lazy afternoon while you're taking a poo poo and disable them in secure boot mode and call it job done, what does a verified kernel get you when your user space is trashed and rootkitted? assuming we're not actually having an unironic discussion about ~*linux on the desktop*~ having any security whatsoever then what we're talking about here is server applications, and you don't use any loving secure boot bullshit to confine untrusted code or security breaches, you use a hypervisor. you know, the solution that has been infosec best practice since the xbox 360 became a thing.

so in short my opinion is give the baby his bottle: force kernel lockdown on if secure boot is on. if you enable the security theater of the latter then why not have the adjacent security theater of the former. besides, it doesn't really affect day to day usage in any meaningful way by the looks of things, since most usely-used xorg drivers no longer do their own user space mmio unmediated by the kernel.

Secure Boot is good the Microsoft of 1988–1999 or so absolutely would have used it as an anticompetitive measure so I can see where they’re coming from

I don't think there ever was a teamviewer compromise, what happen was password reuse and people with old clients that didn't change the access pin each time you launched it. You can disable the pin entirely though.
