arghh, the version of systemd in Ubuntu 18.04 is two versions too old for DNS-over-TLS

correction: ARM TrustZone is a special secure hypervisor, and comparing it to Intel ME or AMD PSP is unfair

@xenon you want -u

@xenon -U is update, not username

why not use a normal implementation written in java? i guess because they had all this code generation/cross-compilation tooling laying around and figured they may as well use it

did you know: graal, a thing that lets you run various other languages on the jvm, has an implementation of regex

that's right, it compiles regexes to java bytecode

the reason is some languages need perl-compatible regular expressions and the Pattern class offered by Java itself is not perl-compatible

@ben i don't know the details

i seem to remember some forms of modern sleep requiring the ME though

my favorite feature of AMD Ryzens is they have two management engines!

the platform security processor is a full ARM core with its own management engine, TrustZone

@ben also surely that'd break various system functions like sleep

@ben still has a management engine

these restrictions disqualify at least:
- basically any CPU made more than 8 years ago (slow)
- recent OpenPOWER chips (expensive)
- ARM (management engine)

also that doesn't cost thousands of dollars

gimmie a cpu that can go reasonably fast and has no management engine. pleas.

@flussence @codl whAT THE FUCK

@sc if you're feeling dangerous you can do a recursive sed on all dotfiles in your homedir and /etc replacing your name, but this is... very dangerous, depending on how unique your name is.

if you're feeling tedium, you can do a recursive grep in the aforementioned locations and manually correct the files

@sc customarily, uids for real users start at 1000, and therefore, if you are the only user on the system, your uid will always be 1000, but this is not exactly a safe assumption. not all distros start users at 1000 (some go as low as 100) and they are assigned sequentially

@sc a lot of programs make the decision to store your username instead of your user id specifically to survive config copies across installations where your uid is different for any reason

@sc I am still dealing with the fallout from config files I've carried over from the install where I did this

@sc source: i did this once

@sc in theory there are three places your name needs to be updated, but that will only update the passwd database and your homedir name. anything else storing your username might break spectacularly and you are better off making a new user.
