  • 1970 was during the cultural revolution. In that year, the world population was 3.68 billion, and the population if China was just shy of 830 million - China had 22% of the world’s population, so if they held (only) 20% of the world’s prisoners, they’d have a lower than average incarceration rate.

    The same is not true for the US today, we have less than 5% of the world’s population today.






  • Only about 10% of the working population in the US is in manufacturing, so 20% more people that would want to work in manufacturing is quite a lot. It’s impossible to undo the automation that has happened to date, though. Worse, if more people work in manufacturing, the pressure on wages and the pressure to automate can both increase.

    Even if we stop all imports and make every finished good purchased in the US here, it’s far from enough to bring us back to the historic levels of employment in manufacturing.



  • We used to have good, strong open source tools made out of C (which is a lot like steel - it can only be worked by blue collar computer nerds with muscly brains). Now that steel core is corroding because of the influence of hackers and other white collar computer sorts with their creative problem solving, and unintended uses of memory.

    That new corrosion is called rust, and it eventually appears on every C project that’s left outside, unless someone comes along to brush it off occasionally.












  • The actual question asked was “Do you think if you were playing your very best tennis, you could win a point off Serena Williams?”

    This leaves huge ambiguity. How many points are we playing? What’s the setting? Does it count if she double faults, or only if I win the point by something I do?

    If it’s a full set, and any point I get regardless of why I get it counts, I think 12% is probably low. Consider the huge advantages most amateurs have of doing very confusing things, and possibly getting some mercy after its clear there’s no true competition to be had, I would give quite high odds that she loses at least one point.

    If this is more like a sudden death, “I’ll bust out my secret serve, and get a point off her in one shot”, 12% is stupid high.

    I have no idea which of those (or the myriad middle options…) People thought they were answering, but for a male with typical bone density, a 120mph serve wouldn’t be enough to drive through your skull, but it will give her a point if it hits you in the face. You have nearly 500 milliseconds to dip out of the way, and let it go sailing over your head for that single fault.


  • In order to make sourkraut, you need cabbage, salt, a knife, a cutting board, a big bowl, a scale, and an appropriate storage container for fermentation.

    Start by rinsing the outside of the cabbage. Peel off any leaves that are damaged badly, cut out any smaller bad spots, then quarter each head, remove the core, and cut small strips. Weight the cabbage you have remaining, divide the weight by 50, and put that much salt together with the cabbage strips in the large bowl. Mix the salt and cabbage occasionally, and either punch it, or squeeze it. After 2 - 4 hours, there should be a good bit of liquid at the bottom of the bowl.

    Transfer the cabbage and the liquid to your fermentation vessel. Use weights or a plastic bag full of water to make sure the cabbage is below the salty water. Wait for 6-12 weeks, checking on it at least once per week.

    Lots of things can be used for fermenting, but the best is a stone crock with a lid that has a water seal around the outside, and a gas release valve on top. The cabbage can smell strongly during fermentation, so get approval from anyone you live with before attempting this recipe.
