I’ve had pretty good results with Wings3D actually, as opposed to Blender. For proper CAD you can try Solvespace, which also sucks but at least has so little to it that you can learn to use it if you remember the idea of solving systems of equations at all.

I don’t think ActivityPub is set up for one server storing and forwarding a whole feed of everything, like Usenet. Right?

But you can, in fact, be too careful. Availability is one arm of the security triad.

If whatever complex configuration you have set up to avoid exposing something to the Internet is incompatible with something and what you wanted to do can’t be done, or if you look and see that setting all that up would be too hard and don’t bother to expose the service at all, then your security posture is incorrect because your service is just as unavailable as if someone else broke it.

That certainly sounds like a thing you would want, nay need, to fix.

Probably.

This sounds like a bug in the distro packaging of the module, or maybe in Grub. You don’t want to try and install any kernel package, or make your default boot option any kernel package, that the wifi driver package doesn’t declare compatibility with.

But nobody’s package manager knows to do this by default when the driver package is installed, and most packaging systems might not even be able to articulate that constraint.

I mean if you put up an Internet-facing unauthenticated file acceptor it will quickly become stuffed with all sorts of garbage and aspiring malware. You definitely don’t want to hook that up to an untar and exec loop, even with some notion of sandboxing. It will just start mining Bitcoins or sending spam or something.

But if it is built properly, with only authorized users being able to upload stuff, and a basic understanding of not dropping stuff where the web server will happily execute every PHP web shell someone sticks in the slot, and the leverage to threaten people into not uploading pictures of their own or others’ butts or Iron Man (2009), I don’t see why all but the file-uploading professionals should immediately give up.

You could definitely build something like this. You definitely want either human review before execution or a fair amount of sandboxing for whatever your students submit.

Do you want students trying to brute force or exfiltrate whatever test data lives in the server? If not, either they should just have the test cases already, or they can get back how many/which of the secret test cases they passed along with their grade, so showing them the results live might not be so important. Unless you want something like “you have 3 tries to pass the secret tests so you can get a hint that your own tests missed a case and go back and try to guess what it was”.

You also might want to invest time first in test harnesses for the students to run themselves, because you want them to learn good practices like coding against a test suite. If nothing else it makes it easier to make the auto-grader later if the students’ code is all already hooked up to the same test framework.

Teaching students how to use fully use a multi-user Unix system can for some topics put unnecessary faffing about between the students and what they are trying to learn (are you teaching front-end web dev or something?), but in a lot of cases your students might actually be better served by something that makes them touch the deep magic than by a slick web UI that handles everything for them, as long as you turn it into a learning experience and not a protracted period of bafflement.

Does your school not already have some kind of shared CD department server/Unix environment for the students that could get you out of account management?

Also, the Right Way to get the code to the server is probably going to be Git and not a tarball. The students could/should be set up with a Git forge and indoctrinated in never leaving their code on their laptop to be sat upon and lost.
