    This is, in general, a good statement of a durable problem one can 'solve' profitably. Basically take a problem that is hard to do 1:1, systemize it such that you can easily tune t…

    From the article -- In coffee shops and in the low-lit corners of bars, professionals are sharing dreams of “disappearing” or “living on a farm somewhere” or “going off the grid.” …

    In my opinion it carries much truth. Somewhere in Google's archives there is a message I sent to the OC that said, "The department of philosophy does not ship solutions to real pro…

    In my original comment I linked the nature study that looked at farmers doing both. The "but if we don't plant crops we'll starve!" argument is just silly for a number of reasons, …

    The "Elevator Problem" (and the "Street Light Problem") were both CS 200 exercises when I was in college. Along with a bunch of other 'game' type systems like 8 queens, Hanoi tower…

    Yes, if farms went 100% from agriculture to solar we wouldn't have enough food :-) And we'd have anywhere from 100x to 1000x the entire power demand of the planet in energy. Solar …

    Its a fair question, California agriculture tends to use 11 trillion gallons (34e6 acre feet[1][2]) of water annually. (about 1,700 Googles worth). Generally from a market driven s…

    In the US at least there is a lot (and by that I mean like maybe more than half) of civil case law around seller liability for defective or 'dual use' products. In the 70's some ci…

    3D walkthroughs are absolutely the OG[1] use for head mounted displays. I had an interesting experience of a realtor who had a couple of Vision pro headsets that they would let you…

    Not surprisingly, the Wikipedia article has a good list ( https://en.wikipedia.org/wiki/Dither#Algorithms ). The 'cool kids' these days tend to use something called 'blue noise' wh…

    Yeah, I've got one of the Seeed Studio ones (running TRML) at the moment.

    Its a great idea, I think they should read the papers on dithering (I've got a color e-paper display and you can get a lot less noise than that by better dithering). The interestin…

    In terms of parallel headlines we're in the 1998 :-). This was market behavior during the last 18 months of the dot com bubble, then it burst. Plan accordingly? Always hard to time…

    Exactly correct. This technique has been used again and again to discourage competition. I was asked was they could have done to encourage competition and I said, "Lobby to make th…

    Sort of? Everything is weight. And since it isn't a design feature to lay down in water there isn't any weight budget for making that modality survivable? So typically when it fall…

    And I sit corrected as it was able to lay down without rupturing the tanks and 'sploding. So that's another win. What I find really amazing and cool is that while its reentering th…

    Yup. Some of the Youtubers (like NASA Spaceflight) had video of it hitting the water pretty fast and hard. That said, this is the only test failure so far. I'm cautiously hopeful t…

    Quite the achievement, congratulations! I'm really curious to see how things unfold when tens of private companies can launch payloads into LEO.

    While difficult to control (as a study) it would probably be a solid basis for a PhD in anthropology or sociology. If you could compare two cultures, one which was exposed to the k…

    I would strongly disagree with the idea that 'low-hanging fruit' is gone. > But knowing how to do those things in the 2000s is not the same as inventing how to do those things or e…
