Inductor,

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.

AM radio law opposed by tech and auto industries is close to passing | Ars Technica (arstechnica.com)

A controversial bill that would require all new cars to be fitted with AM radios looks set to become a law in the near future. Yesterday, Senator Edward Markey (D-Mass) revealed that the “AM Radio for Every Vehicle Act” now has the support of 60 US Senators, as well as 246 co-sponsors in the House of Representatives, making...

Inductor,

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.

Inductor,

If you use btrfs snapshots and systemd-boot instead of grub, then be carefull restoring updates from before a kernel update.

If I understand it correctly, with systemd-boot the kernel lives in the EFI partition, while the kernel modules live in the main (btrfs) partition. If you restore a snapshot with a different kernel version, it doesn’t restore the kernel itself, but the kernel modules have different filenames, which stops the system from being able to boot.

At least that is my understanding of the problem, from having to debug it twice (just start a live-boot system and use Timeshift to restore the system to after the update again). The next time I install Linux, I think I’ll go with grub instead of systemd-boot.

That being said, I really like btrfs snapshots as a sort of “almost backup” (still do regular backups on an external drive). They are quick and easy, and most packet managers can be setup to automatically make a snapshot before installing/updating stuff.

Inductor,

Thanks for explaining it! So systemd-boot finds the kernel in the EFI partition, which it then loads, and then that kernel loads another kernel from the main partition, which is then the full OS.

Is there a reason it’s done this way, and not just the bootloader loads the main kernel?

Also, are the two kernels the same, or does this use two different kernels?

Inductor,

That makes sense. It looks like a really clever way of letting the boot process allow for basically any arangement. Thanks!

Inductor,

No problem, thanks for replying.

Inductor,

Are you perhaps looking for an Expression?

I think that is probably as close as you can get to what you want to do.

Inductor,

This is pretty cool, thanks.

Inductor,

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

Inductor,

He got better.

Inductor,

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.

EN: A question for the LogSeq experts: is it possible to design the different graphs differently? I always have several graphs open at the same time and would like to recognise immediately which graph I am in.

DE: Eine Frage an die LogSeq-Experten: gibt es die Möglichkeit, die verschiedenen Graphen optisch unterschiedlich zu gestalten? Ich habe ständig mehrere Graphen parallel offen und möchte sofort erkennen, in welchem Graphen ich mich befinde.

Inductor,

Yes, I think a lot of the config is per graph. That means you should be able to set custom css or stuff like journal queries differently for each graph.

Inductor,

Under config.edn at :default-queries. Those are the queries it shows under the current journal page.

In config.edn you can also set all sorts of other stuff like which features are enabled and what the default page/sidebar is.

Inductor,

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.

Inductor,

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

Inductor,

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.

Inductor,

Are you using Bluetooth headphones?

If so, you might want to look into turning off bluetooth absolute volume. It’s supposed to keep volume syncronised between your bluetooth device and your phone/laptop/etc, but some headphones don’t seem to support it, wich can end up with them setting their internal volume to max.

Inductor,

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.

Inductor,

That looks really cool.

Inductor,

Thank you

Inductor,

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.

Inductor,

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