  • Btrfs is well supported.

    Btrfs uses snapshots and subvolumes. It is not a traditional partition and can restore to itself.

    I think Timeshift is primarily a snapshotting tool for a quick rollback if something breaks. I would not consider it a full backup tool, there are tools that are much more robust and configurable for keeping files safe and elsewhere.

    For stuff that is still maintained but also legacy, military and contracting benefit from being a pretty insular community. Contractors are full of military retirees. What this does is give a pool of people who worked with the products for a very long time on one side who move over into maintaining them on the other, less knowledge is lost. It still happens and things must change eventually, but they manage to delay things where someone else like a bank might have a harder time when their knowledgeable employee leaves and they’re hiring people off the street.

    Red Hat has long benefitted from being the primary enterprise Linux company based in the US (no, we don’t count Oracle). SUSE created US-based Rancher Government Solutions to get some of that business and it seems to have been getting a lot of interest, despite being early days. They did a good job of focusing on modern technologies and immutable systems.










  • Yes. In low orbit like the space station they mostly deal with atmospheric drag, even just gas molecules cause it. The ISS is has a “reboost” on a regular basis, often from arriving spacecraft but it can use onboard thrusters.

    At much higher orbits the gravity of the sun, moon, differences in earths gravity, and even the tiny force of photons from the sun striking the spacecraft (solar radiation pressure) contribute orbital decay. The Vanguard I satellite was the fourth satellite in space and was expected to stay up for 2000 years, but thanks to solar radiation pressure and some atmospheric drag it’s more like 240.
