  • Ad others have said, nextcloud won’t rescan or reindex on a reboot. no idea why sync thing does, and surely there must be some way to disable that, too. I’m still hesitant to recommend NC as it’s somewhat fragile, needs way more babying than I’m willing to keep up with and just does too many things, none of them anywhere close to “well”. File sync on real computers works solidly if you have a reliable connection (don’t get me started on Android).

    Have you considered using a real media-hoster, like Jellyfin (or like a dozen others)? Jellyfin works fine for music (the are other music-only solutions though). There are plenty of clients that can stream, and have offline support (download a subset/albums/playlists) for things like laptops, phones, … The server can usually transcode audio formats that a client can’t play, in real-time, if needed.

    Edit: I realize I wasn’t clear as to what this means in practice. You essentially get a self-hosted Spotify. Your library, run from your server, optionally you can connect to it from anywhere.







  • I’ve used windows since the 90s. Not once have I intentionally used WordPad.

    It did open by default for some file types for a long time (.doc), usually mangling the content cause it couldn’t actually handle them properly. I think it was also the default for .txt files at some point, causing many curse words when editing plain text files, that invisibly weren’t so plain any more after… Programs expecting a configuration fine really don’t like that sort of thing.

    So: I’m very ok with this. Just install LibreOffice or something if you needa Word-like experience. Install notepad++ for anything “plain”.


  • Scroll down a bit in this article. There’s a list of what each of the available keys are required to provide. A “key” in this context is basically a notch in a certain location, which then defines the meaning of the various pins of the connector. Some devices have multiple keys, as some of the specifications have a common subset. Like key A+E is common, because E provides almost everything that A does, so a device that only requires the common interfaces can work in both. Cars that rely on one of the exclusive interfaces will have the specific key of course. This A+E communication is often used for WiFi cards.

    Sockets always only have one key though, for obvious reasons.

    Edit: correction/clarification



  • Normal bikes that you just push aren’t that stable without a rider, but you can get it some distance. They still fall over rather quickly. That’s mostly the form of the handlebars like gnu commented. And yes, without a rider, the gyroscopic effect is relevant. A bike weighs let’s say 15 kg, and a rider is commonly like 75kg. Of course removing like 80% of the weight changes if the gyroscopic has a meaningful influence. Add the rider back, and it becomes negligible again.

    This is of course even more pronounced if you push only a wheel with nothing else, then there’s nothing left but momentum and the gyroscopic effect.

    The reason you lean into a turn is exclusively the centrifugal force (not sure that’s the right twin), if you don’t you fall over because you have nothing to turn against. Changing direction needs something to push against.


  • The gyroscopic effect of slowly spinning, light bicycle wheels is negligible compared to the weight of the bike and it’s rider. If it was what keeps you upright, riding a tiny scooter-thing with skateboard/inliner wheels would be impossible. I mean those without motor, pedals, where you push yourself forward with one foot on the ground), often for kids.

    What actually keeps you upright isn’t a physical effect, but just training your brain to instinctually keep you upright. While you’re moving, turning the handlebar effectively moves the bike below you left and right. So if you start tilting to the right, you turn right (slightly) so the bike/scooter is moving below you to compensate. That’s why learning to ride anything that is balancing on 2 wheels takes a relatively long time, but only once. Then your brain knows what to do, and it just works without thinking about it.
