This article is a bit of a confusing mess, mostly stemming from confusion between two vastly different technologies that unfortunately share the same name. Shaheds and counter personnel quads deployed in Ukraine are vastly different technologies. Shaheds, for a lack of a better word, are essentially cheap cruise missiles which are effective because countering them currently usually requires an overly capable and much more expensive counter air missile. Doctrinally except for asymmetry of their cost, they are used much the same a cruise missile would be.

As for antipersonnel quads, Ukraine currently uses 7-8 inch ones. They are not small, quite loud and not exceptionally maneuverable. They are also extremely fragile and can be shot down by hitting just about any part of the quad. Also the thing about being difficult to detect using radars is just not true. They have a fairly large radar signature relative to their size which is also fairly unique because the spinning propellers cause Doppler shift on the rotating props. Small autocannons are already being developed for this role and in the urban environments similar systems using nets are being considered. There are also some prototypes of special rifles or rifle attachments for counter drone use being tested in Ukraine for infantry use.

The two most realistic dangers come from concealing them in shipping containers and then deploying them deep behind enemy lines (I am fairly sure this is already illegal in most jurisdictions) and targeted assassinations, where defending against drone threat is not that different than defending against other assassinations threats (concealed bombs, gunmen, snipers etc.).

It’s a task much harder to RL and much more subjective. I don’t want to say we won’t get there, but let’s just say that LLMs could “write” well enough since gpt3.5 era and I don’t think the pleasantness of the prose improved dramatically since then.

And subjectively the explanation LLMs currently provide are usually horrible, horrible enough that I usually just instruct them to provide me human written literature I can read.

3blue1brown helped me quite a bit when I needed to learn calculus ahead of school curriculum, the same could be said for circuit design and a few other things.

In general most that an edutainment can give you is awareness that something exists and a bit of motivation to get you going and there is some value in that. Whether on the whole it’s a positive thing is a bit harder to say.

This is mentioned under every Firefox discussion despite being possibly years away from being generally useful if the will ever progress to that point.

It’s not really a feasible alternative.

There is just A LOT of data available- usually an order of magnitude more than in any other related problem.

And general weather forecasts are not that hard - we have semi useful forecasts for more than 50 years. It’s when you want to do something special: long range, nowcasting of convective storm, other extreme weather etc. that is hard. And even then it’s as much a problem of input data accuracy than the models themselves.

If in 17 hundreds you wanted to choose a language that could be deciphered, say, also in China, Latin was a much better choice than any native language in various vicinity.

I keep coming back to In Memoriam AHH way more often than I would expect; it’s really a great piece of poetry.

I guess we got the first paperclip maximiser.

I am wondering for whom this new device even would be. Because phones work quite well for this use case and much more and everyone already has a phone.

Woodland strawberries grow even better somehow. We used to have them planted at the garden, then a few years ago we removed them and planted something else and this year I was surprised to find that they somehow survived and moved a few meters away from where they originally were.

They also taste better in my opinion.

I would tend to agree unless you need those gpio pins. Then there are few other good options.

Most software is much simpler than a c compiler.

I have recently needed to read a skill document because it was more understandable and more through than the official document.

Competitive programming scene always included offline competition and with AI they are becoming more important (and in general they were more fair even before). If CTFs are to survive, they should probably try to adopt this strategy.

You could even go so far that anything loaded on your computer is fair game, but not more than that (certain competitive programming competition for example allow unlimited amount of paper material - for CTFs you probably need much more than that, therefore electronic).

Sort of. There are a bunch of timing attacks bug in general it still works fairly well.
