    Inflation alone:

    1911 - £550 is now £51,173.17
    1923 - £700 is now £33,435.46
    1935 - £750 is now £42,132.29
    1983 - £32,200 is now £100,020.67

    If it's £1m now then that would "only" mean a 20x increase since 1911.

    Yeah, I prefer readability over code golf.

    Yeah, I just smashed the input strings into a map, e.g.

            p1poss := map[string]int{
                    "A X": 1 + 3, "A Y": 2 + 6, "A Z": 3 + 0,
                    "B X": 1 + 0, "B Y": 2 + 3, "B Z": 3 + 6,
                    "C X": 1 + 6, "C Y": 2 + 0, "C Z": 3 + 3,
            }
    

    Didn't even have to parse/split the incoming string.

    If a series of still images all show some part of the ball was in then you have no proof that the ball ever went out.

    The still image they chose was the one where the least amount of the ball was still in.

    Could it have been completely out at some point between frames? Maybe, but if you can't find any proof that the ball was ever out then you have to assume it was still in.

    Here's the one they were showing on TV, the lighter part of the ball is the bit that is still "in".

    Ha, discussions of semantics always leads me to these points recently reiterated by the venerated pg: https://twitter.com/paulg/status/1598273­760318361600

    It seems that in cryptocurrency discussions this is more evident than anywhere else.

    Looks like the very edge of the ball could still be breaking the plane of the line…

    Exactly. There are 10 types of people in the world, those that understand 3D geometry and the intersection of planes and lines AND binary, and those that don't.

    Doing them in Go this year (first time round, rather than Perl first and Go second).

    Goal is to keep up as long as I can until I run out of time and it starts to impinge on job. (Usually somewhere around day 17 Eric chucks a stinker in there that takes more than an hour.) From here I'll try and finish them all as close to Day 25 as I can, but usually I get the final stars sometime between then and Jan 1.

    Second goal is to have each day run in under 1s elapsed (on my relatively quick laptop).

    Third, eventual, goal is to have all days run in under 1s elapsed in total. Have done this for one year but not all.

    (Another goal is to get my repo of solutions sorted out and timed properly with a good summary/totals page so I can see my progress for this last one. I've also not done all of the years in Go, and going back and doing that will definitely be a good learning exercise.)

    Day 1 in Go: https://gist.github.com/alexgreenbank/19­f63ed9c29316aefb1171bc558b8606

    (No point tweaking that any further, runs in the lowest time I can reliably time and would be easier to extend to handle n highest rather than 3, etc.)

    That last one is just cruel.

    The problem with the "billionaires must be geniuses" is that many people think that wealth must be somehow proportional to intellect, i.e. the more money = the cleverer they must have been to earn it.

    Many of the billionaires are just "not-thick" and were just plain lucky to be in the right place at the right time and had 4 or 5 consecutive bets come in. There are a whole load of cleverer people who made millions but didn't get the luck to convert this into billions.
