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?

I don’t know, I didn’t make this.

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

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.
