No problem, thanks for replying.
I’m a programmer and amateur radio operator.
No problem, thanks for replying.
That makes sense. It looks like a really clever way of letting the boot process allow for basically any arangement. Thanks!
They do, but compounding errors are always a problem with inertial navigation.
Instead of GPS, they can use fixed radio beacons like VOR and TACAN (which I think are both just US systems, but there are similar systems around the world and at major airports). This is basically the system that was in use before GPS.
EDIT: grammar
Thanks for explaining it! So systemd-boot finds the kernel in the EFI partition, which it then loads, and then that kernel loads another kernel from the main partition, which is then the full OS.
Is there a reason it’s done this way, and not just the bootloader loads the main kernel?
Also, are the two kernels the same, or does this use two different kernels?
If you use btrfs snapshots and systemd-boot instead of grub, then be carefull restoring updates from before a kernel update.
If I understand it correctly, with systemd-boot the kernel lives in the EFI partition, while the kernel modules live in the main (btrfs) partition. If you restore a snapshot with a different kernel version, it doesn’t restore the kernel itself, but the kernel modules have different filenames, which stops the system from being able to boot.
At least that is my understanding of the problem, from having to debug it twice (just start a live-boot system and use Timeshift to restore the system to after the update again). The next time I install Linux, I think I’ll go with grub instead of systemd-boot.
That being said, I really like btrfs snapshots as a sort of “almost backup” (still do regular backups on an external drive). They are quick and easy, and most packet managers can be setup to automatically make a snapshot before installing/updating stuff.
It automatically replies when it can read/summarize a site, but that isn’t always possible (maybe it has problems with some paywalls).
If you decide to set up an SDR for ADS-B, you might want to consider setting up a WebSDR with something like OpenWebRX. This would let people listen to all the signals in the bandwidth that you set.
If you’re interested, receiverbook.de is a list of most WebSDRs.

That looks really cool.
I’d like to elaborate a bit on why DNS can be used to track you.
Nearly all web traffic is encrypted (https), you can check by looking at the padlock next to the URL in your browser. But DNS requests aren’t encrypted by default. This means anyone, most likely your ISP our the admin of your home network, can see what domains you’re accessing. That means just google.com, lemmy.world, etc. and not lemmy.world/post/… This isn’t a huge amount of info, but it does tell anyone who’s looking approximately what you’re doing (googling something, looking at lemmy, etc.).
To fix that there are a few different ways to encrypt DNS requests, the most common of which (afaik) is DNS over HTTPS, which will encrypt DNS requests like any other web request your browser makes. I don’t know why this hasn’t been made the default yet. Firefox has a setting for DNS over HTTPS, it calls it secure DNS.
Have you tried using an automatic CAPTCHA solver (e.g. Buster)?
A small, cheap holographic projector (as in projects a glowing volumetric image into the air that I can wave my hand through). It would probably work using femtosecond lasers, but making the optics small and cheap would be difficult.
The referendum was (if I understand it correctly) about adding an advisory body of indigenous people to parliament. This wouldn’t have given them any power to make decisions, only to advise parliament on things.
The No Campaign just straight up lied to people saying it would let them write laws, take away your land, etc…
Not a classic book, but Artemis Fowl. Disney managed to confuse fans of the books and newcomers to the series alike by adding a McGuffin that was unnecessary, bringing the antagonist from the second book into the movie on the first book, and mangling the relations between the two main protagonists beyond recognition.
Something similar happened last year. A company that made eye implants to help blind people see went bankrupt, and suddenly they weren’t around to repair/replace/remove the implants anymore.
Not necessarily, depending on how you’ve set it up, the bicycle has to connect to their servers to unlock. So if they shut down the servers, you can’t even use the pedals.
Here’s a video about it. (in German)
This mostly wasn’t actually Google, the website it refrences was written by ChatGPT, Google’s crawler just found it and shows it in the summary.
I know as little as you do about selfhosting, but I just want to point out, if ip a
generates a convoluted/confusing output, I would recommend using hostname -I
instead. It just prints out all your IP-addresses, with no additional info.
