  • 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.





  • There’s one gun show near me that allows private sellers to register for a table. The only time I’ve ever seen it is people in a historic items collectors club that show up, and I’ve only ever seen one with a gun to sell that was in working order and manufactured post-1899. He wanted $5,000 for a beat up m1917 Enfield. I don’t know whether he was stupid, or looking for someone else who was.


  • There is a movie called “The Godfather”, which depicts a fictional war between mafia families in the US. In the film, there is an older generation that operates on a kind of respect system, and attempt to keep each other reasonably balanced, in both power and money terms. A drug dealer enters the picture, and attempts to murder Michael Carleone’s father (who is the Godfather). In response, Michael plans to meet the drug dealer and a corrupt police captain, sneak a gun into the meeting, and shoot them both. That plan works.

    Later, the Godfather dies, Michael takes over as the head of the Carleone family, and plans assassinations of all of the older generation of every other family in a coordinated attack, during his father’s funeral. That plan works too, leaving him as the most powerful survivor.




  • I ran out of crtcs, but I wanted another monitor. I widened a virtual display, and drew the left portion of it on one monitor, like regular. Then I had a crown job that would copy chunks of it into the frame buffer of a USB to DVI-d adapter. It could do 5 fps redrawing the whole screen, but I chose things to put there where it wouldn’t matter too much. The only painful thing was arranging the windows on that monitor, with the mouse updating very infrequently, and routinely being drawn 2 or more places in the frame buffer.



  • I think we’re still headed up the peak of inflated expectations. Quantum computing may be better at a category of problems that do a significant amount of math on a small amount of data. Traditional computing is likely to stay better at anything that requires a large amount of input data, or a large amount of output data, or only uses a small amount of math to transform the inputs to the outputs.

    Anything you do with SQL, spreadsheets, images, music and video, and basically anything involved in rendering is pretty much untouchable. On the other hand, a limited number of use cases (cryptography, cryptocurrencies, maybe even AI/ML) might be much cheaper and fasrer with a quantum computer. There are possible military applications, so countries with big militaries are spending until they know whether that’s a weakness or not. If it turns out they can’t do any of the things that looked possible from the expectation peak, the whole industry will fizzle.

    As for my opinion, comparing QC to early silicon computers is very misleading, because early computers improved by becoming way smaller. QC is far closer to the minimum possible size already, so there won’t be a comparable, “then grow the circuit size by a factor of ten million” step. I think they probably can’t do anything world shaking.





  • Modern operating systems have made it take very little knowledge to connect to WiFi and browse the internet. If you want to use your computer for more than that, it can still take a longer learning process. I download 3D models for printing, and wanted an image for each model so I could find things more easily. In Linux, I can make such images with only about a hundred characters in the terminal. In Windows, I would either need to learn powershell, or make an image from each file by hand.

    The way I understand “learning Linux” these days is reimagining what a computer can do for you to include the rich powers of open source software, so that when you have a problem that computers are very good at, you recognize that there’s an obvious solution on Linux that Windows doesn’t have.






  • Real everyone-eats-ice-cream-and-dances-all-day hasn’t been tried either. Just because you describe a set of circumstances doesn’t mean those circumstances can exist, and it especially doesn’t mean they can be stable long term.

    Scarcity is a fact of nature. You cannot rationally distribute scarce things without knowing people’s preferences, so you either need to continuously solve the economic knowledge problem (which requires a huge state apparatus, which will be taken over by a dictator), or a means of exchanging goods between people to better suit their preferences (at which point you have invented capitalism).
