    It used to be common for clocks to be driven directly off the electrical frequency. The US Navel Observatory would call up generator plants and tell them to slow down or speed up a little to make a correction to all the clocks. I’m not sure if that still happens, though.


  • There’s a guy out there who made a reversible NES emulator, meaning it can run games backwards and come to the correct state. He made a brilliant post on Reddit /r/programming linking his ideas for the emulator to quantum mechanics.

    Then he was asked why he didn’t distribute his program in git. He said that he didn’t know git.

    To me, that’s a pretty good example of the difference between computer science and software engineering.


  • Finland isn’t just another NATO member, either. It puts Russia in a hairy strategic position.

    In a war directly against NATO, Russia would have had access to the Atlantic through the Baltic Sea by way of St Petersburg. Now, though, NATO controls much of the Baltic Sea, and St Petersburg is in easy striking distance from either Finland or Estonia. It’s also easier to hit the big Russian naval base at Murmansk. NATO can basically bottle up Russia from having any access to the Mediterranean and Atlantic.

    Not only that, but NATO has less to worry about for supplying Estonia, Latvia, and Lithuania. Russia could have cut them off between the Kaliningrad exclave and their ally Belarus, but that’s less viable now.

    Putin knows all this, and has to calculate what it means for starting anything. He’s boxed in and he knows it. Really shows how much he failed merely by invading Ukraine at all.












  • Be careful what you wish for. Congress started looking into video game violence in the 90s, threatening to put some regulations down. The industry responded by creating the ESRB and its ratings system, and congress left them alone. It’s questionable if congress could have actually done anything that passes constitutional scrutiny, but the industry would have had to spend a lot of money to fight that battle, and this was a better outcome for them.

    Now, I think that was initially a win for the average gamer–nothing gets banned, and the industry comes up with universal ratings guidelines. However, just like the MPAA rating system, it can be used to bully out independents. The ESRB also creates a framework for legally defending the industry’s ability to put lootboxes and other exploitative gambling mechanics into games. Now you need to supervise your kid playing FIFA more than any Mortal Kombat game.

    You would have numbers 0-9 plus two more digits (could use A and B, but any two symbols will do). The advantage is being able to cut things in thirds and quarters as well as in half. Cutting by a sixth is a bonus, as well.

    RPN (reverse polish notation) is a different way of doing arithmetic where the order you write it naturally determines the order of operations. Do you know those Facebook memes where people get different answers for seemingly simple math equations? RPN does away with that. There is one and only one right way to interpret an RPN equation, and you don’t have to remember any order of operation rules to do it.


  • What base 12 gives you is a lot of common divisors: 2, 3, 4, and 6. Base 10 only has 2 and 5. Base 16 only has 2, 4, 8.

    The practical upshot of this is that you can divide things evenly in more ways. Particularly when wanting to divide a board into thirds. Having 12 inches to a foot is actually helpful there, though it falls apart as soon as you get larger.
