  • Also it seems to be a good energy storage…for cases where you have irregular energy production. Create hydrogen via electrolysis using the energy surplus from wind, photovoltaic etc.
    And if you need the power, you get it back via fuel cells.

    I think I saw a documentary about the shetland islands, where they have (or had) a power surplus from wind farms mich grater than they where able to transfer to the main land.

    I guess these are the cases which make sense…but creating another supply network to bring the hydrogen fuel everywhere might not be the way to go…

    I have a remote backup setup at my parents, which consists of a rpi4 and an external hdd (old NAS HDD). The rpi also has a wireguard interface running. If I need to back stuff up (via a restic-rest container) I open the vpn from my side, start the container, mount/decrypt the hdd and trigger the restic update. Afterwards everything gets disconnected again.

    The rpi needs to be always on and you need to be able to forward a port to the rpi.

    The data should be secure though, as the disk is encrypted and not mounted. (You can even store the decryption key on your side of the network, so you need the vpn to be able to mount the hdd)










  • I still love the trackpoint and use it almost exclusively if the notebook is not connected on the docking station.

    It is just awesome if you can control the mouse while still keeping the hands on the middle of the keyboard.
    It’s so much faster than to kove up and down and also more ergonomic, especially in the train when the laptop sits on my lap.
    The middle button enables easy scrolling on webpages (although the vim browser extention makes it even easier ther) or documents…

    Nothing else I used was able to beat this setup. And I used a lot of different devices over the tome
