There are 2 short segments in the video showing the actual performance and thus far it is a complete [1] failure [2].

The guy has a talent, and he put together a nice prototype based on OpenRocket [3], but with all due respect, this is not a rocket, and you are not going to win any war with this toy, even if all your enemy has are rocks thrown at you from pretty much similar distance.

The remix of computer games / Ukraine / Martin Luther King / Vietnam / David Koresh just adding more to the amateur spirit and confusion.

I'm surprised nobody else has pointed this out. The entire YouTube video has only two short clips of the actual rocket being fired, and in both cases the clips are very short and only show the rocket being fired and then following an erratic flight path, and then get cut before showing the rocket hitting anything.

For all the technical info given in the video, there is a curious lack of any data regarding the actual accuracy of the system. What percentage of rockets tested managed to hit anything and at what range?

I’m using an ASUS NUC 14 Essential Kit N355. It’s a bit more expensive than the Pi 5, but also more powerful (8 cores and decent GPU). There is also a more affordable N150 model. And even lower budget are the N150 mini PCs from Chinese manufacturers, but they often mess up things like cooling in a hardware revision (compared to the favorable review that you’d read).

And forgot to mention this before: Intel CPUs with built-in GPUs have very performant and energy efficient hardware video codecs, whereas the Raspberry Pi 5 is limited and lacks software support.

And what is the idle power draw that you're seeing on the NUC? Out of the box or did you have to mess around with BIOS and powertop?

FPV drones cannot have powerful GPU yet to enable truly autonomous flight. And the issue is not only weight/energy restrictions, but also cost.

You don't need a super powerful GPU to do computer vision. There are cheap small devices that can do it.

I wonder if kids today will look back with nostalgia about all that time they spent watching "Mr Beast" videos where he did some dumb stunt or flashed money around for YouTube views. Will there be a Mr Beast revival in 20 years where a new generation of "content creators" fondly recreate the video where he swam in a swimming pool full of jelly (not sure he did that one yet).

Mark Rober did that one

It's hard to believe such an in depth overview of the anthropology of marriage skips the massive elephant in the room: that polygynous societies were widely found to be in a perpetual state of civil war and seem unable to develop stable, modern institutions. When a substantial part of your young men have no chance of ever buying themselves a wife, the only way they can be recognized and respected as adult men is to join a militia that promises one, or at least gives them guns so they can aquire by force the cows they need.

The corollary for western monogamous society should be clear: traditional marriage is not strictly repressive, it's also a form of egalitarianism and redistribution of social capital.

If we dismantle marriage and let raw pastoralist dynamics run rampant, we might very well see the same hypergamous tendencies and that many of those excluded from the love market take up "other", less peaceful pastimes.

If that's the case, then how comes China, which has a massive excess of males, hasn't erupted into civil war yet?

Sorry, but how would this have prevented the xz backdoor? The article seems to be insinuating that it would have, but I don't see how it could.

Except that slaves also make new slaves that can be sold.

I really dislike this idea that slavery was just a cultural aberration and not economic. For one thing, that lightens the moral stain of slavery adjacent activity, most notably colonialism and the exploitation of the colonies. This never went away. Economic colonialism exists to this day. We just call it “outsourcing”, “offshoring” and “subcontracting”.

Offshoring generally improves the lives of the people who get the offshored jobs. Usually foreign companies pay more and have better working conditions than the local companies.
