Why compute Pi, that pesky mathematical constant that is the ratio of a circle's circumference to its diameter, out to 10 trillion digits? Because climbing mountains is hard and plenty of people have already done that.
But Pi? No one else has done this. ja0hxv wrote yesterday that he had reached that ridiculous number after starting on October 10, 2010 - but 191 days of actual computing time due to his machine crashing. Luckily he had a modern computer. If he even did one calculation per second on paper it would have taken him over 310,000 years.
Stand in awe and read about it here and then, if your Japanese is up to par, see the details here.
