  • Chemicals like sodium lauryl sulfate and other fatty acids with organosulfate head groups, which are much more powerful surfactants than the fatty acid sodium salts you get by reacting lye with a fat (like vegetable oil). “Traditional” soaps like that also contain glycerol (formed when the lye cleaves the glycerol backbone off of a triglyceride), which acts as a humectant moisturizer.

    Technically, at least in the US, chemicals like SLS aren’t legally classified as soap, and must be called a detergent. Which is why so many products are called things like “body wash” and “body bar”, and you wont find the word “soap” on their packaging.



  • I didn’t bother to read the paper, but the article says the system produced “10s of nanoamps at 10s of microvolts”. I’ll just assume each of those values are “100”, since that’s the highest value you could describe as “10s” of something.

    That works out to 0.01 nanowatts. For comparison the tiny solar panel on a solar powered calculator might produce 0.0075 watts, or 750 million times that amount of power.

    In reality, since wattage is a multiple of volts and amps, lowering both of those figures from my highball estimate would massively decrease the wattage. The solar calculator probably produces billions of times more power than this 1 foot long cylinder.

    So, i think its neat that they were able to measure an effect, but the article really should not even be mentioning power generation.



  • This sort of thing is really common in video games where you’re able to move in zero G.

    In the few games that have accurate zero G movement people get really confused. They’ll hold a movement key the entire way to a destination then smack into it because they didn’t realize they’d have to hold the opposite key for an equal amount of time to stop. Or they’ll fly a certain distance like that, then want to make a 90° turn, only to keep careening off in the direction of their initial travel with a slight bend to it.


  • huge fucking place basically 50 mini countries who mostly hate each other.

    First, stop with the 50 countries crap.

    Next, the size of your country has zero, literally nothing at all, to do with transportation within an individual city. Get the “america special” shit out of your brain, please.

    New York does 8 million transit trips a day and it’s just a Lil state

    3.6 million people pass through this single building once a day every day:

    The rail lines in the Greater Tokyo Area serve in excess of 40 million people per day.

    If US cities really were so big and busy and extreme compared to the rest of the world like you seem to think, they would have a larger need for rail transit, not a lesser one. A rail line has a higher capacity than a highway lane, by at least an order of magnitude.

    I am asking you again, please get the “we are so special and big and extreme nowhere else is comparable at all, no one else could even comprehend it” crap out of your head.











  • The absolute epitome of non-AI slop has got to be these creepy videos that were on YouTube back in ~2017:

    https://en.wikipedia.org/wiki/Elsagate

    Its exactly the kind of thing you’d expect would be the product of AI, but it actually came before AI. I think a lot of it was procedurally generated though, using scripts to control 3D software and editing software, so different character models could be used in the same scenes and different scenes could be strung together to make each video.

    I think a similar thing happens with those shovelware Android games. There’s so many that are just the same game with (incredibly poorly done) asset swaps that I think they must just make a game once and then automatically generate a thousand+ variations on it.


  • They might be generated for the purpose of creating adversarial images that appear relatively normal to a human but confuse AI image recognition. You can see an additional layer of weird patterns on top of them too.

    IMO this is not a particularly annoying captcha though. I’ve had some where the text instructions are so indirect and strangely phrased that it’s not even clear what you’re supposed to do.
