Fun fact, live A/V can not be cryptographically verified in real time.
You have you batch up 5-10 seconds of data and sign that.
If you try to sign each frame/packet, your CPU won't be able to sign fast enough. This is why e2ee videoconferences are symmetrically encrypted and all content is unsigned. You know it came from someone in the conference, but you can't prove from whom (cryptograohically speaking).
Maybe with custom encryption hardware this could be done fast enough that humans wouldn't notice the lag of the pipeline:
capture frame -> hash -> sign -> encrypt -> tx -> rx -> decrypt -> verify -> play
It'd still be tricky to get the data around to each component fast enough. Having an FPGA with an integrated NIC that would accept raw audio and video frames and deal with hashing, signing, encryoting, packing them up and shoving them over to the switch all in one device would be pretty slick.
In a world of quality deepfakes made easy, this could be just the ticket to restoring faith that something is genuine.
If you'd like to go bare metal (or a VM), you can use these to automatically install and configure a bitcoin full node, lnd, and lnbits.

Wonder how many hops to cross the country, from Midwest to pnw? #wishlist nostr:npub16v82nr4xt62nlydtj0mtxr49r6enc5r0sl2f7cq2zwdw7q92j5gs8meqha
There's a limit to 7 hops (to avoid flooding the network) and the default is 3 hops.
The current ground record for one hop is 205 miles from one mountain top to another. We have the Rockies that could help, but the curvature of the Earth is still going to be a limiting factor.
I suspect it may be possible some packets through with some geosynchromous, low Earth orbiting satellites, directional antennas, careful antenna positioning, and using 7 hops. But that's a lot more than a hobbiest project. Last I checked it was about $40,000 to put a small (15 cm cube) satellite into orbit. At that cost, you better be darned sure you get it right on the first try.
š You clearly don't remember the days when Network Solutions had a monopoly on domain names. $15/yr is half price before you account for inflation
If only I had the dancing baby gif from the 90s right now...
Wow, that's a unique recipe! Very cool
Are you growing those in a greenhouse?
If you want a geek yo get in shape, buy them a couple meshtastic devices and a bicycle.
Everything else will just fall place naturally.
If you recently character attacks against #GrapheneOS developers, you might want to read this thread for some more context.

Yeah, ActivityPub sysadmins can see all the activity of their users, just like centralized services.
ActivityPub beats nostr in account recovery. Passwords can be reset. That feature being exploited depends on the server (big instances are very similar to centralized services, small instsnces are more likely to do a better job at sniffing out the scammers).
User responsibility (low). Typically excellent support from your instance as well as the community.
ActivityPub's interoperability matches nostr
It doesn't have a single point of failure, but it's not as resilliant as nostr, so in the middle on that one.
And I think nostr probably wins on everything else.
Moving servers requires the server's cooperation to keep your followers. So, it's possible unless your instance shuts down unexpectedly. Your old posts don't move with you (but they continue to exist on the old server until it shuts down). If your instance is down you can't post nor see your feed. Posts are not cryptographically signed.
Your instance is not a central authority. You can use the same account for Pixelfed (Instagram clone), Mastodon (Twitter clone), Lemmy (Reddit clone) and so on. But your account is usually tied to an email address. It's not strictly required, but it's so common I would say it's fair to say you have to give your instance admin a functional email address.
Almost all of it looks good to me.
I would strongly disagree with "privacy" being set to "high" for nostr. You can't even have a followers-only account on nostr, whereas you can on basically every other platform (and protocol).
When everything is public and it's trivial for anyone and everyone to track everything you do by default... I wouldn't call that "high privacy".
Other than that, there are only a couple other improvements that I can think of:
1. Have some kind of color coding or iconography to make it easy to compare at a glance without reading anything (e.g. red, yellow, green)
2. Include ActivityPub as another decentralized protocol. I get that it's hard to balance overwhelming the reader and leaving out other options. There are protocols like Briar which have real privacy, security, decentralization and identity, but lack in portability and interoperability.
I'd call privacy on ActivityPub to be medium, nostr = low, and centralized platforms = medium.
Other than being chonky, it does look nice
It's possible they also have developers from the United States of America on the team
That seems like it would be at least an equally big trust issue. That is, if you trust the team in the first place that is, rather than trusting the third parties who look at the differences between AOSP and GrapheneOS
And here's a shot of the finished prototype. The rounded one is a lot bulkier.
Does anyone know what the satellite icon means in #meshtastic?
There's an example on F1v3 in this screenshot:
https://github.com/meshtastic/Meshtastic-Android/issues/1647
https://meshtastic.org/docs/software/android/usage/
Doesn't explain it, nor does it explain the number next to the satellite.
And here's the old one that curled.
Not sure if it was the design or me leveling up my 3d printing skills, but the green ones I just printed seemed to hold their shape. I'll assemble them tomorrow and see how the compare side by side.
Keyloop got all messed up on the first and second prints. Strung right over where the hole should have been.
Cleaned up the first two and printed a third with tiny supports that came out better:
Got the #solar power monitoring working on the #meshtastic node on my bench!
Right now it's just connected to a wall wart, but it'll measure solar production once it is on a roof.
I'm going to print one out at super high quality (to get the curves as round as possible) and see what it looks like.
Fun fact: I tried rounding the corners just a tiny bit initially and the whole case peeled up and warped during printing. It'll be interesting to see how this one comes out now that I made it a little thicker and the curves more pronounced.
Unlock the signet, in the client select Backup to file from the Device menu, Save. That file is encryoted and you can restore it to another device.
And the PS2 thing was mainly for me since I use Qubes and don't want to attach a USB keyboard to dom0. I just listed the extras for sale because they're a byproduct of custom hardware development and not doing anyone any good setting on my shelf.
