@inference @404zzz @thebiologist1117 The performance is good but it quickly becomes clear that it is a sketchy descendant of Arch Linux with some of the best wallpapers. Performance grows worse as new sketchy applications are installed.

The wallpapers are pretty cool but the system as a whole makes me want to move back to an FSF Approved Distro. God forbid if you want to use it for development. It's a distribution that demonstrates that apt might not be perfect but it is better than pacman.

The strong suit of the distribution is the wallpapers and some of the drivers. It will break on update just like Arch. Security is sketchy and perhaps the worst I've seen. There are many issues but I don't want to ramble on.

@inference @404zzz @dushman @thebiologist1117 That's correct. Not many people would realize that nor what Libre Linux is.

I don't trust the microcode anyway. Perhaps it's safer to use it but if it was designed correctly, we wouldn't have to talk about bandages.

@AmpBenzScientist @404zzz @dushman @thebiologist1117 Microcode is running in proprietary x86 and ARM CPUs whether installed or not. All you're doing by not installing it is not updating it. It's still built into mask ROM on the CPU die itself.

If there's a backdoor, it's unavoidable, but you're at least protecting yourself against typical security issues against normal people, such as Spectre and Meltdown.

@inference @404zzz @dushman @thebiologist1117 I'm aware of the microcode that goes back to 70s. I suspect that the patches aren't worth using and that the system can't be trusted even if fully patched. It's a flawed design and perhaps worth the risk in some uses to not patch the microcode.

I could very well be wrong but I'm not suggesting that it's the best decision. Imagine screwing up so badly that most of the computers in the world are vulnerable and continuing to sell processors.

@AmpBenzScientist @404zzz @dushman @thebiologist1117 That's literally what security is. Nothing is 100% secure. Even the best systems, whether software such as Qubes OS or OpenBSD, or hardware such as HSMs and hardware encrypted drives. There are always flaws, and patches are essential to fixing issues which were not known.

Microcode updates are the same as any other security patch and should be treated the same way.

@inference @404zzz @dushman @thebiologist1117 I agree but some people like to explore. A flawed Lenovo Thinkpad UEFI allowed researchers to document what AMD's PSP was capable of.

This just effectively reverse engineered what it does. Nothing special about it. It's well known that both AMD PSP and Intel ME control the x86 cores from a low-level system management interface and won't even unlock to start the cores if they are broken or the signature doesn't verify. Is irrelevant to microcode. Whether you install it or not, you simply can't escape PSP or ME; only way is to not use x86 or ARM. Even ARM has TrustZone (which is what PSP is based on).

@inference @404zzz @dushman @thebiologist1117 RISC-V is even getting something that should do the same thing.

The researchers found that the firmware loaded from UEFI and it turns out that AMD wasn't fully honest about PSP.

There's a rumor that Intel, AMD and ARM were included in SIGINT for the NSA.

@AmpBenzScientist @inference @404zzz @thebiologist1117
It's physically impossible to design literally perfect hardware or software. Something being flawed from the get go doesn't mean you should just avoid fixes or mitigations.

@dushman @thebiologist1117 @inference @404zzz Sometimes the flaw is so severe that the device should be recalled but a quick patch is cheaper and doesn't damage a reputation much. I don't update firmware or microcode on some of my personal devices because I like to explore. I've discovered a few things but I never had the resources to fully take advantage of what I found.

It would be easier to develop an exploit than my goal of making it function with open source firmware.

I'm a very niche case. If I physically own something I should be able to make changes to it.
