Same! I’m on Ubuntu and Pop these days but I fondly remember my old distcc build cluster…

Portage is still far and away my favorite package manager.

atzanteol,

I’ve really grown to like yakuake. I always have a sorta “main terminal” where I have a tmux session going and now I do that in yakuake so it’s available on all desktops and easily put “out of the way” when I don’t need it.

I'm so frustrated rn.

I have been distro hopping for about 2 weeks now, there’s always something that doesn’t work. I thought I would stick with Debian and now I haven’t been able to make my printer work in it, I think I tried in another distro and it just worked out of the box, but there’s always something that’s broken in every distro....

atzanteol,

Then stay away. If you don’t like to tinker with things it’s not for you.

atzanteol,

You can install vulkan-tools (ubuntu package name - not sure if it’s the same for your distro) and running vkcube. It’s a simple vulkan app that will display a rotating cube using vulkan. It will also spit out the GPU that it’s running on.

If it reports your nvidia card and the cube looks good then your drivers may be fine and the issue is with Steam and/or this application specifically. If not then there’s an issue with your drivers.

Occasionally when I’ve had a kernel update or something the nvidia drivers have gotten borked. Removing, re-installing, and rebooting has helped. Something like this:


<span style="color:#323232;">apt purge nvidia-driver-*
</span><span style="color:#323232;">apt install nvidia-driver-535
</span><span style="color:#323232;">reboot
</span>

They link doesn’t say the jwst uses Linux. Just that python is used by the jwst team.

atzanteol,

I think you need to learn more about how databases work. They don’t typically reclaim deleted space automatically for performance reasons. Databases like to write to a single large file they can then index into. Re-writing those files is expensive so left to the DBA (you) to determine when it should be done.

And how are you backing up the database? Just backing up /var/lib/postgres? Or are you doing a pg_dump? If the former then it’s possible your backups won’t be coherent if you haven’t stopped your database and it will contain that full history of deleted stuff. pg_dump would give you just the current data in a way that will apply properly to a new database should you need to restore

You can also consider your backup retention policy. How many backups do you need for how long?

Planning on setting up Proxmox and moving most services there. Some questions

I am currently running most of my stuff from an unraid box using spare parts I have. It seems like I am hitting my limit on it and just want to turn it into a NAS. Micro PCs/USFF are what I am planning on moving stuff to (probably a cluster of 2 for now but might expand later.). Just a few quick questions:...

atzanteol,

Use ZFS when prompted - it opens up some features and is a bitch to change later. I don’t understand why it’s not the default.

atzanteol,

I haven’t done it - but I believe Proxmox allows for creating a “backplane” network which the servers can use to talk directly to each other. This would be used for ceph and server migrations so that the large amount of network traffic doesn’t interfere with other traffic being used by the VMs and the rest of your network.

You’d just need a second NIC and a switch to create the second network, then staticly assign IPs. This network wouldn’t route anywhere else.

atzanteol,

This seems to be a “widely believed fact” but I haven’t seen any real data to back it up.

Looking to make the switch

Hi everyone, looking to make the switch from windows. I’m reasonably technically apt but not a programmer by any means. I’ve been doing some homework on which distro I would like to use and pop_os kinda feels like the right direction. I’m running an Nvidia 3060TI on a Ryzen 5600 chip set on an Asus tuf motherboard. Any...

atzanteol,

There are few comments more useless than “I had some random error on unknown hardware with distro X”.

atzanteol,

Just install one. Find out.

atzanteol, (edited )

Just friggin’ install it. People spend so much time debating “which distro should I install”. Toss a dart at a board and pick one. Install it. Get your hands dirty and go. You’re not naming your first born you’re trying a new OS.

atzanteol,

For desktop apps maybe. How do you run a flatpak from the cli? “flatpak run org.something.Command”. Awesome.

Both suffer from not making it obvious what directories your application can access and not providing a clear message when you try to access files it can’t. The user experience sucks.

atzanteol,

It’s not a “language” issue it’s a “computer” issue. This math is being done on the CPU.

IEEE 754

Some languages do provide for “arbitrary precision math” (Java’s BigDecimal for example) but it’s slower to do that. Not what you want if you’re multiplying a 4k matrix every millisecond.

atzanteol,

At first I was with this but the first set of questions is so stupid that I can’t see that being a good idea.

Somebody just code up a bot that picks a random mainstream distro everytime somebody asks “what distro should I use?”

atzanteol,

FWIW I manage docker compose files with ansible. Allows me to centrally manage them without the need to go logging into multiple vms. I also create a systemd service file to start/stop the containers (also managed with ansible).

That said I’m starting to switch over to k8s as well (also with microk8s which has been the easiest to work with). Definitely overkill but I want to learn it.

atzanteol,

Like I do any other system. rsnapshot nightly to backup server.

atzanteol, (edited )

Not sure about others but in PopOS (and I assume Ubuntu) it’s pretty simple. Probably easy with most distros.


<span style="color:#323232;">apt install gnome-desktop
</span><span style="color:#323232;">apt install kde-standard
</span><span style="color:#323232;">apt install xubuntu-desktop
</span><span style="color:#323232;">apt install cinnamon-desktop-environment
</span><span style="color:#323232;">apt install xfce4 xfce4-goodies
</span><span style="color:#323232;">etc.
</span>
atzanteol,

How do you know if it’s open source? Well if it’s called something like “huggingface” or “redpajama” there’s a very good chance it’s made by people who have no marketing department. So good odds it’s free.

atzanteol, (edited )

Let me save you from reading this.

Why I left nobara: because I did… Then scattered rambling that goes nowhere and certainly doesn’t end with a twist.

atzanteol,

I’ve been running Linux since the 90s and use popos. Nothing “beginner” about it.

Upgrade vs Reinstall

I’m a generalist SysAdmin. I use Linux when necessary or convenient. I find that when I need to upgrade a specific solution it’s often easier to just spin up an entirely new instance and start from scratch. Is this normal or am I doing it wrong? For instance, this morning I’m looking at a Linux VM whose only task is to run...

atzanteol,

Yeah, my first thought was “this is doing containers the hard way”.

lxc and docker are your friends.

atzanteol,

They did it “for the vibes”

Vibes are just as important to free/open source software as proprietary software and although there were solid technical reasons for the port, the PR outcomes are added benefits.

I broke nextcloud and i cant fix it

I managed to install and set up nextcloud snap on my ubuntu server a couple months ago. I haven’t used it since and now I tried to log in to it but I forgot the username and password. I tried uninstalling and reinstalling the snap to reset the data but i couldn’t access the web page. I couldn’t find anything online. Any...

atzanteol,

Have you tried reading the docs?

docs.nextcloud.com/…/reset_admin_password.html

atzanteol,

Cool story. 🙄
