Zoho works well for me with my own domain (though I am on the old free plan that allows IMAP, while today the free plan only supports webmail or their own app). I also know someone who uses Tuta without problems sending to Google and Microsoft.
Which parts of computer science are you interested in? I would suggest looking at some different universities’ current fields of research to find one with a focus that aligns with your academic profile.
You can use this as a starting point in your search, as it has sorting options based on topic https://edurank.org/cs/eu/
It is a public GPG key (not a Microsoft Publisher file) and while I don’t know, I assume it is used to verify that future updates are from Nvidia and not a malicious third party. It is really common (if not required) to install and trust a new gpg key when adding a new repository in Linux package managers, and done for safety reasons without privacy implications, and I am guessing this is what Nvidia is doing here.
Where do you see any indication that it is used for identification of you/your machine?
In my experience, Chat GPT is much better at the general programming patterns and concepts than specific API implementations. Especially less commonly used ones, where it often gives a solution that only looks reasonable but uses the totally wrong methods. I guess it’s similar with scraping the HTML of the Ubuntu releases page to get the latest torrent. It doesn’t know the exact HTML layout, so it guesses what is a likely one, even though it is wrong.
If you were using the default port 25565, you could simply have a DNS A record pointing to the server IP. But since that is not the case, you have to additionally set up a SRV record in your DNS. NOIP describes what this is and how to set it up on their service here, but it will of course differ for your DNS provider.
This still requires that the Minecraft server port is directly accessible from the other clients, but it sounds like that is not the problem
Spotify at least does allow you to add local files on a computer, and they even sync tracks to your phone when they are on an offline playlist when the devices are on the same network. I’ve done that myself to get some otherwise unavailable songs into my catalogue, and am thinking of starting the move to owning all my music that way
I quite enjoy challenging my musical knowledge with https://bandle.app/
My own use for OneNote was mainly drawing/hand written notes using a drawing tablet. For that use case, I have replaced it with Xournal++
For other notes written with the keyboard, I use simple local markdown files.
All my notes are synced between computers with Syncthing
I am from Denmark where the biking infrastructure is also pretty good, so I will almost always take the bike if I’m going somewhere that is further than 1 km away (~.6 miles).
But that is just if I’m going somewhere – taking a 4 km walk just for the sake of the walk and getting some fresh air (especially when the weather is nice) is quite normal here.
