  • Backup on different levels, one of my clients who I would say has similar ifrastructure uses following approach:

    • backup on the vm level - backing up snapshot of the entire virtualization guest - at least once a week, always before update/upgrade. These can be big - consider ZFS pool w/ compression and deduplication active - but that is also hw intesive. On the other hand, I don’t think you need to keep more than last two successfull backups.
    • filesystem level - run rdiff-backup against the / of the filesystem several times a day. SInce it is essentially versioning, you are only backing up new changes. No zetabyte needed here, ext3/4 will do.
    • drop database somewhere ideally several times a day - even if there are no incidents, your developers will love you.

    The recovery strategy is as follows:

    • pull the guest out of the last vm backup
    • sync up the files from last rdiff-backup run
    • discuss w/ the developer DB recovery - or just recover the last backup and hope for the best…

    I use my laptop a lot (usually plugged in)

    Warning : I’ve used to fix apple computers back in the day when there were still things to fix, and if this had happened to an Apple device and it had less than 50 cycles on it and was over 6 months from purchase (meaning it went less then 50x under 50% of your full battery capacity), they would refuse to replace it saying it is user’s fault. Nbooks with NiMh batteries could stay connected to power forever, notebooks with Li-ion batteries need to “excercise them”.


  • A colleague wanted to throw out Lenovo IdeaPad Duet 3, 10IGL5 (a tablet pc with IMO cool keyboard that can be disconnected and used over bluetooth, 4 core intel CPU taking like 5W & 8GB of ram). Originally bought for his kid but it is absolutely useless under windows. I’ve tested it with current Ubuntu with somewhat meh results (BT keyboard won’t work, no chance to get the automatic screen rotation going, screwy on screen keyboard) then I have installed Fedora and the thing is absolutely amazing. Everything works out of the box, I haven’t done anything “smart” at all and honestly as a XFCE (still deep in x11) user I am amazed how well the Wayland is doing on this. I would dare to say better out of the box experience than Apple - everything is similarly polished but you don’t have to register / pay anything. Now my teamleader is taking it to presentations. He connects the display over USB-C adapter to the projector, walks over the room and controls it with the BT keyboard - Mac wielding accounts are starting to cry. As docker/podman is native he continues to spin up the whole app in a container - at which point every technical person in the room needs to know what the f is that thing?! They are no longer being manufactured though, newer version does not have that cool keyboard…
