Hey +Xah Lee , her's more about the『㏒』character,

below the Unicode Consortium page about it. Not much said about it, apart that it's "square log" (and not captain log ; although it would have been cool)…
UNICODE v7 http://www.unicode.org/charts/PDF/U3300.pdf
UNICODE v4 http://www.unicode.org/charts/PDF/Unicode-4.0/U40-3300.pdf
(No difference whatsoever.)

Also said, it's an unified Han ideograph & info can be found in the db. Strangely I never saw any maths stuff inside the unihan db when I unpacked it few month ago…

Anyway
// http://xahlee.info/math/blog.html //

Good Day.

Let's go!

The ancient game of go still holds many challenges.   Compared to go, chess is like tac-tac-toe.   There are 255168 possible games of tic-tac-toe.  There are about 10^120 possible chess games.  But there are about 10^761 possible go games!

The main challenge with go is playing it well.  But there's also counting the number of legal positions.

A full-fledged go board has 19 × 19 squares, and approximately this many legal positions:

208168199381982000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

That's about 2 × 10^170.

John Tromp wants to know the exact number.  Why?  Because it's a fun challenge.   He knows an algorithm to calculate this number.  It's very clever.  But it still takes a lot of computing power.

He recently calculated the number of legal moves on an 18 × 18 board.   It took 9 months of computation and 4 petabytes of disk IO on a Dell PowerEdge R820 server.  He did it at the Institute for Advanced Studies in Princeton... that place where Einstein used to hang out.  The answer is:

669723114288829212892740188841706543509937780640178732810318337696945624428547218105214326012774371397184848890970111836283470468812827907149926502347633

To get the answer for a 19 × 19 board will take more work.  Using some very clever math, the task can be split up into 9 jobs that each compute 64 bits of the 566-bit result.   To do this and be sure the answer is right, he needs about 10 to 13 servers, each with at least 8 cores, 512GB RAM, and 10-15 terabytes of disk space.  The job will  take about 5-9 months.

If you want to help out, email him at john.tromp@gmail.com.

You can read more about this here:

http://tromp.github.io/go/legal.html

including the answers for all square boards of size up to 18 × 18.   The most interesting part is the algorithm to compute these numbers:

http://tromp.github.io/go/gostate.ps

Puzzle 1: Can you turn this animated gif into a looped animated gif?   It's from Wikicommons.  It's sad that it plays just once and then stops:

http://commons.wikimedia.org/wiki/File:Go-board-animated.gif

Puzzle 2: This animated gif is just 11 kilobytes.  We could easily afford a looped gif that plays a whole game - say, a famous game.  Wikicommons deserves it!   Can you make one?

I thank +David Tweed for pointing out Tromp's work.  A calculation of the number of tic-tac-toe games is here:

http://www.se16.info/hgb/tictactoe.htm

There seems to be some controversy here: another person computed the number of games counting to as the same if they're related by symmetries, and got an answer of 26830.  Because this is less than 1/8 times the answer above, they can't both be right.

Ever since I got a smart phone in September, I've been playing go with a program called "Go Free".  Someday soon I'll fork over the $1.99 to get the version that lets you play on a 19 × 19 board.  So far I'm just trying to learn to crush the computer on a 13 × 13 board.  I like playing a computer because I get annoyed at human opponents when they beat me, and I don't like that.  At some point I should be able to beat the computer consistently on a 19 × 19 board and then I'll have to either quit or... something else.

Go is full of general lessons about life, which become more profound as you get better... at least for a while.  Maybe at some point it devolves into being "merely technical" - I don't know. 

Unfortunately these general lessons mostly apply to situations where cooperation is not an option.  So it's possible my personality is being warped by playing go.  Sometimes I can sort of feel that happening.

One Year and I just changed the battery of my MS ergonomic keyboard. twice for the mouse. I didn't hoped for such good lifetime.
Despite the shitty function keys it's a pleasant keyboard.

Interesting in #Ruby :
2.2.0 :017 >   a = <<␄
SyntaxError: foo.rb:17: can't find string "␄" anywhere before EOF
foo.rb:17: syntax error, unexpected end-of-input, expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
    from /usr/bin/irb:12:in `<main>'

for:

a = <<␄
aoeui


Although with  "a = <<-␄" it works…
I may be dumb not being able to find something about dochere in ruby but it's weird that a unicode char is working in some case and not on the other… ಠ_ಠ
