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!
Sorry I can't contribute to the topic, but you should know that if she has varicose veins instead of just veins close to the skin's surface, she should get them treated at some point
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.
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
