base12 has the advantage of being divisible by 2, 3, 4 and 6, while base10 is only divisible by 2 and 5.

Optical Character Recognition. Basically just extracting text from an image.

You can do this in VLC, though it’s not very practical. VLC’s equalizer has a preamp slider, it’s just not great if you want to change it all the time.

I’m not an expert, but I guess it would depend on the speed of sound in the rod.

Fun fact about that: in morse code, SOS is a prosign. This means it gets its own special rules.

Rather than being three seperate letters (… — …), it’s one letter without any letter spaces (…—…). This is something that applies to all prosigns in morse code, though most of them are just two letters long.

Also, when sending it on repeat you just continue the pattern without any spaces. Instead of …—… …—… (with a letter space) or …—…/…—… (with a word space), you send …—…—…—…—… and just keep continuing the pattern. iirc SOS is the only prosign where this is a thing.

Other prosigns are for example HH (…) to indicate a correction to something previously sent, and SK (…-.-) (silent key) to signal that you have finished with the current conversation and the frequency is now clear.

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!

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.

This is pretty cool, thanks.

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)?

Amateur radio/ham radio. There are a few ham radio communities on lemmy, but they’re all fairly inactive. I occasionally check on some groups on matrix as well.

The next few years are looking quite exciting for ham radio, because we’re reaching the peak of the 11 year solar cycle. This gives us amazing conditions for long range communication.

While, as you said, both wires will conduct electricity just fine, they will have different AC impedance.

I would guess this wouldn’t make much of a difference if you go Audio->Ethernet->Audio, since sound is at fairly low frequencies. But Ethernet->Audio->Ethernet might have problems with really high data rates, like GiB/s.

I’d try mysterytool -H

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.
