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

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.

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

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.

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.

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.

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.

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.
