It doesn't have a speedometer function, but I selfhost Owntracks for personal location tracking with my Android smartphone.
It has a back end that an android app sends location too, and a front end that displays those location points over a map. It can display lines between consecutive points, show a heatmap of the location points, filter location history within windows of time,, and more.
I can only really speak to your first point. When imported my existing library, I did it using Sonarr/Radarr as applicable. They have a manual import method, here's a description of Sonarr's.
Unfortunately that'll probably work best if they're formatted in a way Sonarr can readily recognize, something like /Season ##/S##E## - .ext. It may take a little work to get there, I found a program called mmv which helps out a lot. It allows you to move files that match a pattern, capture parts of pattern, and use that captured part to name the output file. That allowed me for format entire seasons at a time, but that method does rely on most files having similar names to begin with.
Since Jellyfin v10.6.0, it's had a feature called SyncPlay allowing multiple users to watch the same thing at the same time (coordinates pauses, fast forwarding/rewinding, and all that between clients). I've used it and it worked like a charm, although I did find that not all clients support it.
I doubt Reddit builds a decent search engine, that doesn't actually help them at all.
If users can search, they find a previous post pertaining to what they want to see/know and they move on.
If there's no search, users can't find old posts or comments so they make new posts about a previously posted topic and more comments are made as other users react. That's more content, even if low quality from a user perspective, that shows engagement which can be sold to advertisers.
That's before considering the engineering effort it takes to make a good search engine, constantly fine tune that algorithm, and try to outpace those that are trying to game the search algorithm.
I like Czkawka for detecting and handling duplicate files, similar files, empty directories, and more.
Sunday afternoon, after careful evaluation of a significant security concern, we made the intentional decision to sever our ties to the internet.
I feel like most big announcements like this end up being Ransomware. Cutting off from the wider internet feels like a weird move to defend/mitigate that? Unless it's to reduce exfiltration?
I assume you mean SSL/TLS certificates for internet accessable applications? I use a reverse proxy called Caddy in a Docker container, which handles requests from the internet and directs them to the proper docker container based on the subdomain. It also handles my certificates automatically, requesting a new Let'sEncrypt cert just before the old one expires using a community made plugin.
You may be able to use the CLI tool mmv, which can be installed through the apt package manager. It's great at renaming files that are starting a similar naming convention and ending with a similar naming convention, you could use mmv to move your files. It also suppose sum links and hardlinks. It's what I used to rename folders of tv shows when I need to do that.
It's all about what you value, and supporting the things you love (or rely on, in a more utility sense). I'd value the speed, the lack of data collection that may be used against a user, the speed, the location options, and that same provider being in business for time to come. When I'd need a good VPN, nothing else will do. That seems worth the couple of USD per month to me, whether that VPN is for obscuring traffic I don't want others to know about (whether it'd be because of those facilitating the connection or the other end of the connection).
It does get disabled to the Quarterback, however I believe the Head Coach can flip between channels to talk to Offensive and/or Defensive coordinators during the play.
