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:
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.
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.
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?
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.
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.
We’re getting well away from the topic now. It depends on what you mean by “replace”. Railways and canals exist side-by-side as different solutions to similar problems - sure. And some railways have replaced some canals. But the panama canal will not be replaced by a railroad for example. It couldn’t do the same job. The pros/cons of each option depends on many factors.
The analogy is poor for comparing software. Linux distros will likely replace X11 with Wayland over time. To do the same thing that X11 was doing. It will be replaced “in place”. The very same thing you were using with X11 will now need to work on Wayland. This would be like running your barges on the railroad? Maybe? Depending on how you squint?
I wouldn’t expect my barge to work on the railroad. I do expect that Firefox will run on Wayland after having used it on X11 for 20 years.
