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.

Matched using perceptual hash algorithms that have an accuracy between 20% and 40%.

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

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.

Here’s a circular rainbow from an aircraft a skydiver:

EDIT: image embedding didn’t work

EDIT 2: not from a plane

EDIT 3: sorry for all the edits, fixed image

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.

AM Radio has an extremely important role in emergency broadcasting, because you can cover a whole continent using just 3-4 broadcasting stations, and it is so easy to demodulate, that you can build completely analog recievers that need no power source (they use the carrier wave as a power source). This also means that AM receivers are very cheap, so in a lot of developing countries the only broadcasts most people can afford, and will reach them are AM.

I think we should keep AM radio around, at least for emergencies.

Also, unfortunately, when HF bandwidth gets freed up, it mostly ends up going to companies that use it for high frequency trading, and not to things where it would benefit the public, like ham radio, or digital broadcasts.

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.

Can I take one end of a cable with me?

What’s the max power I can get from the sockets?

Where does the eject button dump people and can it be set to dump things other than people as well?

Does time continue inside the pocket dimension if no one is inside?

What’s the internal temperature/humidity? Is it regulated?

Can I choose what I take with me, or is it just everything im wearing/carrying?

Questions aside, I would fill it with all sorts of stuff that I might need at some point, but leave enough space for a bed and a desk.

I don’t know enough about the lemmy server to say whether this is a regular issue. I’d just retry creating a user with the same email.

Did it show an error when you tried to confirm your email?

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.
