  • I had the same happen on the root folder on a SATA SSD. The SSD was dying (don’t remember if there was SMART errors, but the dmesg log showed write-errors. I cloned old SSD to a new SSD and haven’t seen the problem since. That was years ago.

    When there are multiple consecutive write errors, Linux will re-moumt the partition as read-only to protect the data. (There usually a statement along the lines of “on-error:remount-ro” for the partition in the /etc/fstab file)







  • For jpg’s, no they will not get smaller. Maybe even a smidge bigger if you zip them. Usually not enough to make a practical difference.

    Zip does generic lossless compression, meaning it can be extracted for a bit-perfect copy of the original. Very simplified it works by finding patterns repeating and replacing a long pattern with a short key, and storing an index to replace the keys with the original pattern on extraction.

    Jpg’s use lossy compression, meaning some detail is lost and can never be reproduced. Jpg is highly optimized to only drop details that don’t matter much for human perception of the image.

    Since jpg is already compressed, there will not be any repeating patterns (duplicate information) for the zip algorithm to find.


  • There’s nothing wrong with Mint, it’s solid. If it works for you don’t stress about it

    The only thing is that it’s based on Ubuntu LTS so it’s packages can be a bit old. Doesn’t really matter much unless you have very new hardware and need the hardware support. Then something Fedora based like Bazzite would be better.

    For getting newer software you can use flatpak/Flathub.

    Bazzite is also “immutable” which makes it harder to break on a system level, but also harder to tinker on a system level. Mint is a “normal” distribution in that regard. Mint does have Timeshift for taking system level snapshots, on the off chance that an update or your tinkering breaks something. Its worth checking that Timeshift is set up for automatic snapshots




  • I think Mint does this out of the box, but check if Timeshift is set up for automatic backups. It’s meant for system-level snapshots (basically everything outside the HOME-folder), so you can easily revert if an update or something breaks the system.

    Also consider some form of periodic external backup of her files and documents in the home folder, to protect against hardware failure.







  • It’s not, unless you know the keys.

    Keys are created by the software/app made by the service provider, like WhatsApp / Meta or Google. How is the key created, and is a copy sent back to WhatsApp? “Securely” and “No” they claim, and you just have to trust them.
    That can change if WhatsApp need to comply with new laws.

    Signal is a bit different because of the app is fully open source, so the code can be audited to verify the integrity of the encryption. They would still need to comply with laws or exit that market, but whatever they do would be 100% transparent.
