    Expose molten ferrous metal to … a magnet.

    Welp…

    Magnets are created by running an electrical current through a material, so there is no need to have a ‘first magnet’. This is happening ‘naturally’ in the earth core, in the sun, and in other stars. (https://physics.stackexchange.com/questions/565245/how-was-the-first-magnet-made)

    So you need to look around and find some magic rocks.

    Natural magnets, called “lodestones”, were found in iron ores (magnetite) from the ancient region of Magnesia, hence the name “Magnet”. (https://physics.stackexchange.com/questions/615500/how-did-magnets-first-come-about)

    Maybe the sword with the stone was just a big lodestone with a sword sized hole in it. Just throwing that out there.

    And one more cool fact…

    Based on his discovery of an Olmec artifact (a shaped and grooved magnetic bar) in North America, astronomer John Carlson suggests that lodestone may have been used by the Olmec more than a thousand years prior to the Chinese discovery.[23] Carlson speculates that the Olmecs, for astrological or geomantic purposes, used similar artifacts as a directional device, or to orient their temples, the dwellings of the living, or the interments of the dead.[23] Detailed analysis of the Olmec artifact revealed that the “bar” was composed of hematite with titanium lamellae of Fe2–xTixO3 that accounted for the anomalous remanent magnetism of the artifact.[24] (https://en.wikipedia.org/wiki/Lodestone)



  • Occam’s razor says the more simple/plausible explanation, that a huge increase in the monetary supply causing higher prices through supply and demand, is about a thousand times more plausible than tens of thousands of corporations simultaneously deciding to coordinate to fix prices despite that it’s in each of their best interests individually to break with that scheme. With no actual evidence of a concerted attempt across the entire economy to fix prices (not to be confused with a couple corporations having board meetings where someone bragged about raising prices).

    Or, in simple terms - it’s not that every single other good in the entire economy has suddenly become worth more as the result of some overarching conspiracy. It’s that they printed a bunch of money and it’s now worth less.

    I would recommend anyone who still believes the “greedflation” thing spends an hour reading some articles critical of the theory. Not really looking for a debate about it tbh.

    AI/ML covers a ton of algorithms, some of them are that boring, some of them aren’t.

    Re above. Take all users who viewed all items. Run a MapReduce to segregate them into pairs. Calculate the frequency of pairs and store the result. That clearer? More expensive than complex.

    And then

    1. Network effects matter, supporting open source software promotes its adoption and lowers barriers to entry for technological literacy and accessibility, accelerating the technological and social development of humanity

    Although that doesn’t have the same ring as “fuck these dumb cult members because i don’t care and they shouldn’t either”.
