<lynn_sh> just checking in again if there is some way to get a spammer flag from registering to be cleared. it says i am in the db 11 times for spamming even though i registered once, and got the secret question wrong slightly and tried again.
<Mutabah> Are you connecting over IPv6?
<Mutabah> There is an entry in the logs saying an IPv6 address appears on a spam database 11 times (iirc it was 11)
spare has quit [Remote host closed the connection]
<lynn_sh> i would assume so, ipv6 is the standard.
<lynn_sh> im not 100% sure what networkmanager is doing with my wifi setup or how to check
<lynn_sh> also it tells me i am banned until [todays date] [hours and minutes before the current time].
<lynn_sh> for instance for todays attempt (i got nothing wrong, filled it in all correctly) You have been banned from this board until Tue Dec 10, 2024 4:17 am.
<geist> huh
<lynn_sh> considering i am not spamming and know i am not, is it possible it's because of the user name im registering with? like this person exists already and has spammed so im getting linked to it?
pabs3 has quit [Ping timeout: 248 seconds]
<Mutabah> The message I saw was that your IP address was listed in a centralised anti-spam database
<Mutabah> Maybe your ISP has been blocked entirely. I'll check when I'm home (in an hour or so)
<zid`> i got banned from sourceware last month
<lynn_sh> my ISP is fritzbox which is like the isp every german person uses
<Mutabah> Username could be it too... I didn't look too deeply into how that antispam system works
<lynn_sh> ty Mutabah
<zid`> Turns out someone tried to ban tencent and typo'd, banned a /14 inside a /10 that my ISP owns, and it made all the netmasks uneven, because they weren't an /8 or a /16 etc. Which meant I needed *two* admins to try to grep for the ban :P
<zid`> i.e ban was on 86.16/14 and my IP was 86.17.xxx.xxx
<zid`> hard to grep for an IP when almost all of the digits are different
<lynn_sh> lol that is unfortunate

<Mutabah> lynn_sh: Have you tried a different username?
<lynn_sh> the username was the issue
<lynn_sh> that's a shame since i would have liked it
<Mutabah> the price we pay. Before that was added, the spam was MASSIVE
<lynn_sh> oof
<lynn_sh> ty. i didnt try a different username just incase i was spamming for real. all sorted now
<Mutabah> Part of the reason I wasn't doing moderation much was due to the spam volume
spare has joined #osdev
<lynn_sh> yeah the unfortunate reality of the modern web. forums are just graveyards of spam :(
<lynn_sh> i was very glad to see such a long standing forum though still around.
<zid`> On the plus side, Mutabah now has a mountain of viagra and his boobs are the size of planetoids

<heat> KERNEL
<nikolar> KRNL
<sortie> The redox people reached out to me about os-test, looking into redox now :) Can't believe I didn't actually test it, was looking through osdev systems the other day
<heat> idc buddy i SENT A FUCKING EMAIL
<heat> i can actually do linux kernel development from onyx now
<heat> finally, the end goal. i have finished onyx
<nikolar> kek
<sortie> heat: You compiled Linux on Onyx?
<heat> i've also done that yes
<zid`> did it work
<heat> i didn't test
<zid`> so it could be entirely zeros? :p
<sortie> heat: https://pub.sortix.org/sortix/screenshots/sortix-cross-compiling-linux-kernel.png ← Welcome to the club (did this back in 2021)
<sortie> heat is now considered elite.
<heat> always has been.
<heat> sortie, are you packaging cpan crap
<sortie> heat: I do package the cpan binary
<sortie> But usually is a losing battle to recursively package other ecosystems
<heat> i think you kind of have to though
<heat> perl seems to be unanimously packaged, and it's also quite important since random packages depend on it
<heat> like git send-email has a bunch of package deps, etc
<heat> python is also somewhat important because you can kind of break the system otherwise, sometimes. pip no longer works on modern linux distros
<Ermine> venv!
<heat> yep
<heat> they recommend either installing thru the package manager, or venv
<heat> (no idea what venv is)
<sortie> heat: Nothing I encountered so far needed any cpan packages installed or packaged on my own?
<heat> git send-email does, and gettext needs some cpan stuff as a build dep too i believe
<heat> in fact lots of email stuff seems to require this particular cpan package (IO::Socket::SSL)
<Ermine> venv is basically a prefix with python binaries and packages
<sortie> heat: perl ships a little bit of the cpan stuff as part of it's distribution, basically some core libraries, yes you do want to package those
<sortie> I ran into an issue updating to the latest perl where the build didn't include some of the stuff that was supposed to be in there, for some reason, breaking some other port builds importing stuff
Leftas has quit [Quit: Ping timeout (120 seconds)]
<sortie> Alright I read the redox documentation. It's interesting. It also feels, well, ... I would say aspirational? It mentions superior security and what not and it doesn't quite feel trustworthy as the actual current security. The disk image appears to have the default root password in a world readable file in the root directory. It mentions that static linking is superior security for handwavy reasons that completely ignore the existence of ASLR and the
<sortie> dangers of bundling old library versions
Leftas has joined #osdev
<sortie> At least in Sortix, I don't pretend. You're warned up front. The documentation is in line with reality.
<sortie> That said, I think redox has some promise, and I welcome it to the world of competing systems especially as it tries to do something novel
<sortie> It could very well get there although for some of its use cases Sortix actually works better today, like the server use I'm trying to do for testing
<sortie> E.g. it has a lack of a sshd shipped with it, the package manager seems to download at 50 KiB/s which takes forever to install gcc
<heat> sortie, it does, but IO::Socket::SSL is not one of those packages
<heat> despite the horribly core name
<heat> i took a while to figure this one out
<sortie> Hmm

<heat> gosh single threaded compilation is so slow
<heat> is this how the other half lives
<zid`> that's why you shouldn't buy webserver cpus
<zid`> I'd rather have four 6GHz cores than 192 1GHz cores
<heat> actually the big problem here is that gettext seems to enable -fanalyzer for its build
<heat> for some reason
<zid`> lol what, WHY
<zid`> it's incredibly ropey and is a diagnostic at best
<nikolar> why would you ever do -fanalyzer in the release build
<heat> i can't tell but i've been seeing shitty warnings and god oh god -Wcalloc-transposed-args
<zid`> mayeb they accidentally committed it
<nikolar> same thing with -Werror
<zid`> I change my local makefiles constantly
<zid`> for building debug
<nikolar> yea
<nikolar> but i don't commit that
<heat> considering they seem to have conf tests for Wno-analyzer stuff, probably not

<GeDaMo> How many cores does it have? :|
<the_oz> redacted
<the_oz> it also redacted redacted with redacted redacted redacted so redacted
<the_oz> therefore you can totally trust us to not breach the illusion of competetive advantage
<GeDaMo> Presumably the "problem" that it can solve is of no practical use to anyone :P
<the_oz> that's per usual
<Ermine> like breaking RSA?
* geist gazes out with an evil smile
<the_oz> just like before, capability is still ephemeral
<the_oz> no matter what shiny platters they show to dumb monkeys

<zid`> you should ask chatgpt
<childlikempress> don't tell me what to do
<zid`> you should tell yourself to ask chatgpt then listen to yourself, because you don't need no man
<nikolar> lel
<zid`> Best part about quantum computing so far is that you need a PhD and a research grant to be able to ask it things
<zid`> because you have to make up some infinite series where all the terms of the wrong answer cancel out
<nikolar> and it can only factor numbers up to like 5 digits
<zid`> leaving you with just the right answer
