  • I have 2 powered RAID enclosures from icybox with 2 multi TB HDD in each one. The RAID is set to mirror the drives.

    They are connected via usb 3 to a raspberry pi which runs borgbackup.

    One is in my own place, just next to the main server.

    The other is at my parents place in another city.

    All my desktops, laptops and servers have borgmatic installed with the two pi’s as two targets. So when I create a backup it gets send to both locations. On my PCs I manually do a borg backup like once a month when I feel like it. The server computers are all on a daily schedule.

    Borg has extremely efficient compression and defuplication. So having 20 historical snapshots of the whole file storage of each device takes about 30% less space than the original size on disk.

    For example my desktop currently uses ~800GB but the borgbackup of said desktop takes only ~500GB.

    The only disadvantage I find is that there is no cross system deduplication.

    The super useful advantage is that I was able to just take the HDD enclosure, plug it into my Desktop and restore whatever files I want. I did an rsync to a blank fs once and it restored everything properly. And it’s pretty cheap. like 150$ total per backup location without any significant monthly costs.

    I used hetzners storagebox for a while for borgbackups but restoring from it was SO SLOW. And my internet connection is not stable enough to do that without interruptions for multiple days. Never again, except for using it as an extra last resort “cloud” backup.



  • I had a case that looked like that, because the nozzle was scraping the previous layer of the print.

    I think that for some reason the layers below were physically taller than in softwas and the additive effect of that stacked and reached critical failure at a certain height. It started as soft scraping and got worse as it went on until it failed like that because it essentially skipped a whole layer. No enclosure/heating chamber btw. It was always the same height for that model, but then a smaller model like a benchie would have no issues on that height. I guess because the filament was warmer due to the smaller loops, so more mendible or less expanded somehow, idk.

    I dried my filament so it stopped making bubbles and ran some filament specific calibration and also I changed the extrusion to be a bit lower. Then the issue was gone.











  • my 2 old phones (usb c) were both replaced because of hardware issues.

    one has a broken power button that is constantly detected as being randomly spam pressed, so as soon as it gets power if it ever manages to boot it either hard reboots itself or tries to call emergency services.

    the other has a flaky usb c that constantly connects and disconnects unless you hold it at a specific angle and the battery is like a step away from meltdown - it can hold charge for a couple minutes.

    I’d be afraid to leave either plugged in at home.

    I guess the article is for people that buy a new phone for fashion, not need.
