  • I’m living on an old farm with lots of junk.

    So naturally I am building an 8 foot tall wind-driven kinetic sculpture of a Wendigo.

    I bought a welder and a cutoff saw. All the materials are retrieved from the trash gully that every respectable high desert property must have.

    It’s a form of cope and even ritual magic for me. Embody the spirit of hoarding and greed so it is vulnerable and can be imprisoned, that sort of vibe.

    It will take all winter to finish it. The rebar armature is flexible and bobs in the wind. I will add sun bleached oak branches to give it flesh.


  • I recommend you try gaffer tape instead of duct tape.

    Advantages:

    • Remains flexible and removable forever.
    • Looks nicer, a cool matte black or manynother colors.

    Where I get off making this recommendation:

    I needed a light-excluding bellows for a photographic project. I made one using black illustration stock and gaffer tape. It worked extremely well on the first version and held up to hundreds of cycles of extension/compression. My application was sensitive to pinhole light leakage and there was none.

    It would have lasted longer but that was the end of that project.

    My two cents. I love DIY stuff!

    Your systemd file looks ok, but I think it’s doing exactly what you are telling it.

    The solution may lie in the backup.service. Is that code you can modify? The OnCalendar=weekly doesn’t specify when in the week the service should run so that config may be vague.

    If I understand the desired function here, you will need the service up all the time. It will just wait politely and occasionally run the specific backup script. It’s up to the backup script to determine when the last backup was made and either exit early because it hasn’t been a week or run the backup and reset a flag file.

    At least that’s the approach I would take. Systemd is a very vigilant, but very stupid, service manager. It just watches and triggers services based on just a few criteria. Any logic more complex needs to go in the service itself.
