Get the cheapest and get a feeling for if this is the right thing for you or not, and if so, what more expensive equipment you actually need/want. You can always sell the stuff you don’t need.

One other thing to consider later would be what lenses you can borrow from friends.

Well the image is based on fedora linux and the tooling was developed by fedora, I believe. I put Aurora Linux on my dad’s aging PC around christmas, because it doesn’t qualify for Windows 11 and 10 ends support soon. In my experience it boots pretty slowly on physical machines (with n=2, fine on VMs though), and it doesn’t reliably wake from suspend, but other that that, it’s completely fine. I did not try to install any other Linux for comparison though

You might want to try using an auto updating bootc based solution instead, such as universal blue with customized images. They have instructions on how to do image customization.

But more importantly: send him something like a NanoKVM along with the USB!

Hab mich nie näher damit beschäftigt, aber https://hedy.org/ vielleicht?

It also means updates are just full system images, so no way for a package manager or differential update to mess anything up. It also means no way of downloading tiny differential updates (if I understand everything correctly).

If you don’t need DX or would like to switch off of KDE, there are other fedora atomic desktop based distributions available.

Oh right, a distribution is just an image, so switching distributions is as simple as switching the base OS image and rebooting.

Not necessarily exactly the same wires, but all rated for 16A, so the circuit beaker will trip long before any wire gets a chance to heat up

Don’t quote me on this, but I don’t think PDFs can usually contain java. It also wouldn’t execute if you don’t have a java runtime.

Either way, java serialization data is not executable, it is just that: data. It doesn’t contain code. You need the matching code already running in order to de-serialize the data.

If your file matches the linked SO post, you don’t have serialized java data embedded in the pdf, but the pdf embedded in a serialized java array. Which, also according to the SO post, is not a valid pdf.

<speculation>
I would assume that the library that generated this file (in the SO case Apache FOP) has a bug where it accidentally serializes the memory array (that holds the generated pdf) to the disk, instead of writing it to the disk. Why do pdf readers open it anyway? Either they incorrectly scan the file for %PDF- instead of verifying these are the first bytes, or the apache library (and possibly other libraries with similar bugs) are or were common enough that accepting this became reasonable.
</speculation>
