After using ext4 for yyyeeeaaaarrrrrsss, when I upgraded my MX21 to MX23 I used btrfs, with subvolumes, especially for easy backup/snapshot/timeshift.
Just at install, super easy, create a small ext4 boot partition on the SSD, then a big LUKS partition, format with btrfs, create subvolumes for / /home /var /swap and that’s it. No hassle with sizing correctly.
btrfs seems pretty stable. I see no diff in performance compared to ext4 because my application are not that dependant to FS speed, and with SSD anyway?
If Linux, use LUKS but you need to enter the passphrase at boot, you can securely put the key in TPM2 I think (à la Windows) but it may be complicated to setup, or just seal the phrase in TPM2 but if you boot on grub you can break grub and replace init with a shell in boot option and have access to the system I think :-/ but a simple crackhead thief would not understand that.
You can also have the key on a USB key, but if on the server and the server get stolen, it’s useless. You can setup a “anywhereUSB” and have your USB key in another room/place, etc, there is others possibilities.
I wanted to unlock with bluetooth but having the bluetooth HW driver and stack in initramfs was nightmarish a little bit :-/
Using un*x since the 90s, this is all I know. I like awk but it can go fucking complicated, I once maintain a 5000 lines script that was parsing csv to generate JavaScript…
Title bullshit, we have multicore machine for years, I can guarantee you this had about no impact else people running Xeon or Threadripper would have saw it at first try 15 years ago.
This looks like to have an impact on the scheduler but not on how many cores are used.
Yes, both are well known and (even if sometimes some people says they have lemons, for both bands) pretty solid, mine is 14 months old and runs 8h/day as my work PC
