  • Yes when it comes to RAID, a UPS is a must.

    Linux MDADM is not resiliency against power lose. And will overwrite from master if they are not equal.

    Cow system ZFS, LVM, BTRFS and similar, have separate metadata table to compare against. But even then they can be affected by write hole in the event of a powerloss.

    If you are thinking it for “backup” for redundancy in case of disc error, a solution can be to use something like borg backup, and a source disk as a BTRFS file system so you can be notified if there is checksum errors.

    A cheap UPS is 60€, it will work good enough.








  • Constant maintenance no.

    Currently I have some issues with the Nvidia driver acting up. So I am getting good at purging it and reinstalling it. Maybe once a month.

    Under Ubuntu desktop.

    My server I have very little issues. For mye Proxmox environments I have a small issue after restart it doesn’t properly month a NFS share. If I don’t do mount -a.

    My laptop I have a constant issue that hibernating don’t work with encryption out of the box. So I have to turn if off or connected it to power. I think there have been mad some progress but I haven’t reinstalled Ubuntu for 2 years.






  • L3 cache is a hardware level function so unless the application like memtest86+ tells the cpu not to cache, everything is cached.

    There are games that is so memory intensive when it comes to IO/s , that the cache plays a smaller role, like “X4: Foundations“.

    /sys/bus/platform/drivers/amd_x3d_vcache/AMDI0101 is a global function. You can use ‘taskset’ to set cpu affinity at launch of application.




  • Okay, imagine your computer is like a big playground.

    Linux is like a really cool, free, and super customizable manager for that playground.

    • Manager (Operating System): Just like Windows or macOS, Linux is the main software that runs your computer, manages all its parts (like the screen, keyboard, and internet), and lets you run other programs (like a web browser or games).
    • Free: Most of the time, Linux doesn’t cost any money to use.
    • Customizable: Unlike some other managers that have strict rules for how the playground is set up, Linux lets you (or people who know how) change almost anything about how it looks and works. This is why there are many different “flavors” of Linux (called distributions or “distros” like Ubuntu or Mint), each with a slightly different setup.

    In short: Linux is a free, open-source operating system that gives you a lot of control over your computer. Many phones (Android is based on Linux!), servers that run websites, and supercomputers use it because it’s powerful and flexible
