  • Floating Point Unit. The thing that does mathematical operations on floating point numbers. It used come separately from the CPU as an add-on chip, but around the 486 era, manufacturers started integrating it on the same die as the CPU. Of course, as these things go, from the system programmers point of view, there is still no difference between an add-on FPU and an integrated one.

    The one pictured here is an add-on FPU for an Intel 80386 CPU.

    Top Left – More or less the default position, sensible enough, if a bit naive. Nothing wrong with this.

    Top Right – Having knowledge is a good thing, and so is making decisions based on sound risk-benefit analysis.

    Bottom Right – Well, at least it’s an informed decision. Just don’t try to pass off the risk on someone else if it backfires.

    Bottom Left – Oooouuuuh, you don’t want to be in this quadrant, trust me…




  • Several years ago now. On at least two of those tries, after maybe a month or some of daily driving, suddenly the fs goes totally unresponsive and because it’s the entire system, could only reboot. FS is corrupted and won’t recover. There is no fsck. There is no recovery. Total data loss.

    Could you narrow it down to just how long ago? BTRFS took a very long time to stabilise, so that could possibly make a difference here. Also, do you remember if you were using any special features, especially RAID, and if RAID, which level?


  • Out of interest, since I’ve not used the “recommended partion setup” for any install for a while now, is ext4 still the default on most distros?

    I recently installed Nobara Linux on an additional drive, because after 20 years, I wanted to give Linux gaming another shot (works a lot better than I had hopes for, btw), and it defaulted to btrfs. I’ll assume so does Fedora, because I cannot imagine Nobara changed that part over the Fedora base for gaming purposes.




  • Pro tier is for Enterprise customers who need extra-long term support and are willing to pay for it. Canonical is meeting a market demand so they can remain competitive for use in those environments, which is good for everyone. It’s benign

    Then please show me the button (and I mean button, not command-line exclusive settings or config file entries in /etc, and certainly not unofficial trickery like third party repositories that replace Ubuntu advantage packages with an empty decoy) that says “Thank you, I don’t need Ubuntu Pro, please stop nagging me about it”.

    Depends a lot on what kind of user. I specified “non-technical” with a reason. I have, in the past, recommended Ubuntu to a small number of friends and family members. These are people who aren’t particularly comfortable using computers in the best of times. They very much don’t need the newest, best and most shiny versions of everything. They need to do billing, taxes, correspondance, email and various other tasks related to their small business, they need that to work reliably, and if at all possible, to work exactly the same way as it did the last five years. And if there is any pop-up they don’t immediately understand (for example because it’s in English instead of their native language, yes that still happens in Ubuntu quite a bit), they will call me on the phone.

    I don’t know if you’ve ever had to support non-technical end-users, but for some of them, even something as seemingly trivial as a menubar that has moved from the top to the side can be issue that needs explaining and training. For that kind of user, I really do want to postpone all updates beyond pure bug and security fixes for as long as reasonably possible. Five years sounds reasonable. Six months does not.
