Not a classic book, but Artemis Fowl. Disney managed to confuse fans of the books and newcomers to the series alike by adding a McGuffin that was unnecessary, bringing the antagonist from the second book into the movie on the first book, and mangling the relations between the two main protagonists beyond recognition.

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..

He got better.

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.

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

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.

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.

As far as I know, there are a few different link formats, and how well they work depends on which frontend you're using:

• amateur_radio
• !amateur_radio@lemmy.radio (The Web interface gave me autocomplete options for this)
• https://lemmy.radio/c/amateur_radio

EDIT: At least using the web app, the first link is relative, and the others are not. So I think the correct format would be /c/<community>@<instance> for communities outside your instance.

Artemis Fowl (Book 1) (he's the good guy in the following books)

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 don't know, I didn't make this.

It automatically replies when it can read/summarize a site, but that isn't always possible (maybe it has problems with some paywalls).

relevant xkcd

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

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

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

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

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.

Thanks, I didn't know where it came from.

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.

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.

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.

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.

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

Edit: see comment

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.

Replaying Death's Door

Flourine by itself is nothing compared to chlorine triflouride (CTF) though.

There were some ideas to use it in rockets, but, as John D. Clark put it:

It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water—with which it reacts explosively. It can be kept in some of the ordinary structural metals—steel, copper, aluminum, etc.—because of the formation of a thin film of insoluble metal fluoride that protects the bulk of the metal, just as the invisible coat of oxide on aluminum keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.

There were a few successful test fires with a CTF rocket on the ground, but to avoid explosions they had go through an elaborate multiple hour long cleaning procedure, and it ended up being too expensive and dangerous.

This is pretty cool, thanks.

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.

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.

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

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.

"subreddits" are communities. You can find them with the search field from your instance, or using the community browser.

Congratulations on passing your exam first try!

Out of interest, what license was it?

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.

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.

I imagine the film crew took out the windows so that they could shine the lights into the plane.
