Too bad that there aren't many details on the wireless link (e.g. frequency, protocol)

I don't understand this sentence: "One caveat to the randomness is that in order to preserve chronological ordering if a client creates multiple push IDs in the same millisecond, we just ‘increment’ the random bits by one."

Nice work. As someone who built physics engines years ago, it makes me kind of happy that solving stacking is still no trivial task.

The LiDAR part is neat. Anyone knows if Google uses this too for mapping?

One can prepend any data to a zip file and it will still be valid.

Now it would be a nice next step if he uses his wifi card's RSSI + Helmholtz reciprocity to verify the theory.

This was also mentioned in an article about the Defcon 22 contest, posted on HN too: https://news.ycombinator.com/item?id=8189549. Apparently, the translation ceased to work now?

I would expect that you need to acquire the raw footage; post processing (and compression) will ruin the data.

The original article states: "One of Python’s most visible users, Dropbox — who also employs Python’s creator Guido van Rossum — recently announced it has migrated major parts of its back-end infrastructure from Python to Go" and refers to [1].

I would like to run a Tor exit-relay, but I am too afraid to do this, as I live in a what used to be liberal western country called "the Netherlands". Where the police sometimes raid Tor exit-relays on purpose, to discourage people from helping Tor [1].

That reminded me of "LoseThos". It would have been an interesting coincidence if multiple people were asked by God to create a 64-bit OS, but it is the same guy; he renamed it into TempleOS.

Not to nitpick, but wifi is radio. The propagation of radio waves depends on their frequency. The frequency wifi operates on is in the GHz, which mostly is line-of-sight only. This is not always practical. See [1] for an overview of frequency and propagation.

I have been wanting to create something similar for years.
Before I had access to the Internet, I used "packet radio", a CB-radio based network (there were/are amateur radio band versions too). The whole Netherlands, as well parts of Europe, were wireless connected (at 1200 baud) and one could send messages via the network of nodes from one side of the country to the other side, usually within days. Or chat with people one could contact directly (usually within ~10 km iirc).
At that moment I didn't realise how awesome it was, but in retrospect it was pure self-organised anarchy, without any commercial or governmental interference.
Regarding this AirChat, it is sad that they, as it appears to me, did not make usage of the expertise from the amateur radio community. Still, I believe that it has potential.

That is a great idea, a series of programming exercises for the Linux kernel. I never needed to do kernel programming, but it always seemed terrible interesting to me. This will probably motivate me to actually do so!
