  • 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.












  • PSA about mini PCs: They might not come with adequate cooling for RAM, leading to potential data corruption.

    (I’m in the middle of troubleshooting/fixing overheating RAM causing memory errors, will post on /c/selfhosted when I have more conclusions).

    TLDR: Bought 3 Minisforum HM90 mini PCs (for Proxmox), equipped them with 64gb (2x32gb) RAM, with a different brand RAM in each PC. All 3 give sporadic errors in Memtest86. The RAM overheats due to the 2 SSDs mounted in the lid blocking natural airflow. With the lid off, or an extra fan installed, there are no errors. The errors were very sporadic: 1 PC gave errors after 1-2 passes, then almost 24hours. Second PC gave errors after more than 24 hours and some cases more than 48 hours between errors. The last PC gave hundreds of errors on the first pas. To be fair, memtest is a synthetic test and the RAM is unlikely to see 100% utilisation in real life, on the other hand the two adjacent SATA SSDs and the NVMe SSD are completely idle during memtest, and will generate extra heat during production use.


  • OnlyOffice is also available as a (offline) desktop office suite, so as a user it’s more like LibreOffice than Collabora.

    My wife prefers OnlyOffice over LibreOffice, as it’s feels closer to MS Office. Also it’s compatibility with MS Office formats is better than LibreOffice.

    I still use LibreOffice for desktop, but I’m not a heavy user. Haven’t tried out Collabora or hosted OnlyOffice for NextCloud yet.
