Happy π day! How accurate an estimate of the value of π does your commit history produce? ``` MAX = (1 << 64) - 1 hits = 0 `git log --pretty=format:%H`.each_line(chomp: true).with_index do |sha, index| x, y = [sha].pack('H*').unpack('Q*').map { (_1.to_f / MAX) * 2 - 1 } hits += 1 if Math.sqrt(x*x + y*y) <= 1 puts hits.to_f / (index + 1) * 4 end ```
