Working on a couple fox designs.

A more detailed and colored version is still being worked on.

But in the meantime I've also made the stylized xenia design by @chromacat248 into a B/W and trans-pride patch.

Thinking about manufacturing them next month.

Anyone interested in them? Poll below

Es gibt ja sehr viele Videos zum Thema "Umstieg auf Linux". Gerade ist von Linux Guides DE eins erschienen, das den Unterschied zwischen den Systemen nochmals sehr gut erklärt.

(Bonustipp im Video: Softmaker könnte eine recht gute Office-Alternative sein - schon lange nicht mehr angeschaut - werde ich auch mal wieder einen Blick darauf werfen.)

Once upon a time in 2005 I attended my first symposium in . It was interesting to be surrounded by so many fellow geeks, most of whom made me feel wholly inadequate but that's beside the point. It's a real shame the event eventually failed. If I were better with faces I would tag people but I'm just not that guy.

@itsfoss my gf and I work using WinOS (company laptop) and she has a personal laptop with WinOS.
I run arch, fedora and Debian server and I still don't think Linux is a replacement for WinOS. I see it in the near future though, containerisation helps with this.

@kernellogger as usual, the point is not that these are bug free, but that they are regression free. The kernel upstream releases break userspace on every new release, and kernel maintainers don't care. See https://github.com/torvalds/linux/commit/a1912f712188291f9d7d434fba155461f1ebef66 for example, as Daan just found out, which removed a mount option without caring that it is still being used, so since 6.8 every btrfs device can no longer be mounted by systemd

@kernellogger That's to be expected, but it is also not the point of them.
I agree they shouldn't need to exist, but the realities of how many many an organization manages their IT necessitates their existence.
The industry doesn't want to go through the withdrawal phase of building a better world.

Why Linux is not adopted on a large scale. Because Linux is too fragmented and because Linux users are evil and don't accept the new. Most want Linux to look like the first version of Linux - the command line (TTY).

Or they see that and horses, just forward and don't accept any other Linux distribution than the one they use.

crismblog,

@visone That's what I do, I teach new users what to choose and help them with information and whatever they need.

There is some good in this fragmentation, but it is too much.

Is there a #linux command that can do timezone conversion on timestamps? Ideally through a pipe?

I want to convert syslogs in UTC to localtime (based on $TZ env).

cat /var/log/syslog | tz2local

@mattcen@aus.social avatar

@phs @cafuego Oh yeah, [0] would be sufficient; I had changed it because the ISO format I was using separated the space with a space rather than T.

mattcen,
@mattcen@aus.social avatar

@phs @cafuego Here ya go:

#!/usr/bin/env python  
import datetime, os, sys  
for line in sys.stdin:  
 line=line.strip().split(' ')  
 print(datetime.datetime.fromisoformat(line[0]).astimezone(), ' '.join(line[1:]))

@itsfoss Getting better. However, three things that I need for a full change-over;

Much better support for Logitech G keyboards. I've used the G15/G510 for well over a decade, and Linux support is poop.

2-channel positional psychoacoustics. Windows Sonic for Headphones is amazingly good at this, even on low-spec USB sound devices.

Battlenet games. Yeah, I'm old, and set in my ways. 90% of my PC gaming time is in WoW. Bnet support is wonky at best.

I love the fact that when people referring to distros hear “it just works out of the box” the first thing they think of is . Say what you will, but this is a huge win for Linux as a whole, because that’s how you bring people over to our side.

Want to run the same command again? In many shells (e.g., tcsh, zsh, bash) you can type "!!" to recall last command and run it. Example:

apt install nginx # missed sudo
sudo !! # this will run sudo apt install nginx

Mamy tu jakiś speców od Dockera?
Próbuję skonfigurować dockera używając podmana i udało mi się uruchomić kontener i podpiąć katalog z hosta do kontenera, ale sieci nie ogarniam.
Kontener jest uruchomiony na zwyklym uzytkowniku na serwerze. Działa dostęp do DNS i webowki z laptopa, ale z androida juz nie i nie mam pojecia co jest. Jak zmieniam dns na telefonie, to wifi krzyczy, ze niema neta.
Ta adresacja takze jest dla mnie jakas dziwna. LAN ma adresacje 192.168.X.X, a kontener ma siec 10.X.X.X.

Juz chyba wszystkiego probowalem. Wylaczylem firewalla na serwerze i chyba wszystko co blokuje reklamy na androidzie, ale nadal dupa.

Jakby kogos interesowalo, to probuje skonfigurowac "Technitium DNS Server"

Dzięki. Już nie trzeba. Problem rozwiązany.
Wyjąłem całą elektronikę na jakiej można było sprawdzić i coś mi nie pasowało, jak się okazało, że z 4 urządzeń tylko na jednym działa, a na pozostałych nie.
Stwierdziłem, że sprawdzę, co po sieci hula i okazało się, że zapytanie DNS dochodziło do sewera, a serwer zwracał pakiet ICMP z informacją, że port nieosiągalny. Jeszcze raz zerknąłem na komendę uruchamiającą kontener i okazało się, że zamiast protokołu udp, dałem tcp i tu był problem.
"podman run -dt -p 53:53/udp" - to jest poprawny fragment. Wcześniej było "53:53/tcp".

Zastanawia mnie tylko, czemu na laptopie działało. Obstawiam, że systemd mial w cache tą domenę i to systemd z laptopa zwracał ip, a nie serwer DNS, ale z drugiej strony, widziałem w logach serwera DNS zapytania i to mnie zastanawia. Jak macie pomysł, czemu tak się działo, to chętnie się dowiem. A może to systemd z laptopa wysyałał zapytania do serwera po tcp, jak nie miał u siebie tej domeny. To jest zagadka.

Przy okazji odkryłem świetny program, o którym wspomnę w następnym wątku. Adminom na pewno się przyda.

@nyx yes! As with all things: test in a duplicate environment first, and make sure you have current backups, but it’s working well for folks already! https://www.reddit.com/r/AlmaLinux/s/X0wA64pIJf
