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.
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.
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.
It might have been the fingerprint sensor. They can be fooled. Mine occasionally thinks the inside of my trouser pocket looks just like my finger.
That looks really cool.
Nope, at least afaik. Prototyping and building cars by hand (without a whole factory set up to build it) is hard. Not to mention extremely expensive. And you have to build multiple (identical) copies of the prototype to get it street legal, because of crash testing. And you have to be able to guarantee that what people build with your kit remains identical to your prototype. Or everyone assembling such a kit would have to build multiple copies of the car and go through the certification process individually.
And of course there are very few people that would want to assemble their own car, so you wouldn’t be able to make a business out of it.
I would also recommend consent-o-matic. It works really well, and has a really simple interface for letting the devs know when it doesn’t work.
Have you tried using an automatic CAPTCHA solver (e.g. Buster)?
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.

Unfourtunately, I couldn’t find a source stating it would be required. AFAIK it’s been assumed that they would use perceptual hashes, since that’s what various companies have been suggesting/presenting. Like Apple’s NeuralHash, which was reverse engineered. It’s also the only somewhat practical solution, since exact matches would be easily be circumvented by changing one pixel or mirroring the image.
Patrick Breyer’s page on Chat Control has a lot of general information about the EU’s proposal.
