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

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.

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?

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.

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.

If I remember correctly, Peter later also became ruler of Earth just through his political influence.

Peter Wiggin (Locke) as well as his sister Valentine Wiggin (Demosthenes) are Ender Wiggin’s siblings. After Ender was

shipped off to military school at age 6

, Peter convinced his sister to write on “the Nets” about the war, posing as adults using the Pseudonyms Locke and Demosthenes. They managed to get a significant amount of influence, especially considering they were like 10 years old.

Also, relevant xkcd.

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…

Ahh, sorry my mistake. I remembered reading a headline somewhere about Google having already implemented it, but I didn’t check. Thanks!

It has allready been implemented in Chromium/Chrome (link). Websites only have to start using it.

Edit: see comment

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)

Did you know that every Apollo mission carried multiple rolls of ordinary duct tape with them.

It was used occasionally to fix broken things like the Apollo 17 moonbuggy.

They have radiators to dissipate heat. And all the required systems to make that work like coolant pumps, as well as heat sinks (or the coolant fluid is the heat sink).

But they also have heaters, to make sure that (especially the batteries) don’t freeze. Satellites hang in a delicate balance between freezing and overheating.

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.
