I’m a programmer and amateur radio operator.

I’m not an expert, but I guess it would depend on the speed of sound in the rod.
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.
Artemis Fowl (Book 1) (he’s the good guy in the following books)
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?
I imagine the film crew took out the windows so that they could shine the lights into the plane.
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.
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.
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…
That’s odd, I’m using Connect and it gets the right post every time so far.
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.
