  • In practice, you would split a disk up to keep /home separate from/ and probably other parts of the filesystem too like /var/log… this has long been an accepted practice to keep a full disk from bringing something production offline completely and/or complicating the recovery process. Now, you could use partitions but once those are set, it’s hard to rearrange them without dumping all the data and restoring it under the new tables. LVM stands for Logical Volume Manager and puts an abstraction layer between the filesystems and the partitions (or whole disk if you are into that). This means you can add Disks arbitrarily in the future and add parts of those disks to the filesystems as required. This can really minimize or even eliminate downtime when you have a filesystem getting filled up and there’s nothing you can easily remove (like a database).

    It’s good to know but with the proliferation of cloud and virtual disks it’s just easier on those systems to leave off LVM and just keep the filesystems on their own virtual disks and grow the disk as required. It is invaluable when running important production systems on bare metal servers even today.

    Hope this helps.

    Ext4 is the safe bet for a beginner. The real question is with or without LVM. Generally I would say with but that abstraction layer between the filesystem and disk can really be confusing if you’ve never dealt with it before. A total beginner should probably go ext4 without LVM and then play around in a VM with the various options to become informed enough to do something less vanilla.




  • As with all tech; it depends. It’s another tool in my toolbox and a useful one at that. Will it replace me in my job? Not anytime soon. However, it will make me more proficient at my job and my 30+ years of experience will keep its bad ideas out of production. If my bosses decide tomorrow that I can be replaced with AI in the current state, they deserve what they have coming. That said, they are willing to pay for additional tooling provided me with multiple AI engines and I can’t be more thrilled. I’d rather give AI a simple task to do the busy work than work with overseas developers that get it wrong time and time again and take a week to iterate while asking how for loops work in Python.


  • “Has the White House considered the possibility that a terrorist could be in the country right now after crossing the southern border?”

    What a bullshit question. The core question is valid, “Has the White House considered the possibility that a terrorist could be in the country right now."

    But the rest is a bullshit political talking point, “…after crossing the southern border?”

    As if we only have one method for a terrorist to get in. Nevermind the northern border, the shores, air flights, and then the truly scary threat that the terrorists were born here and are citizens. But, screw all that, WhAt AbOUt tHe MeXiCaNs!?

    This framing shows that the asker has more interest in building support for a Republican talking point into the coming elections than giving a shit about terrorist threats within our borders (all of them).
