Fabrice Bellard, Pi record

Fabrice Bellard, using a PC, Computed π to about 2.7 trillion places, claimed to be the latest world record. (previous records are made by super computers that costs millions.) He's home page is at, which details this among other things. A highly accomplished C programer. Probably the world's top 100 or even 10.What's personally interesting is that he also created a Emacs-like editor: His other accomplishments include: FFmpeg (for processing multimedia data (e.g. audion and video)), QEMU (cpu emulator).

Basically hare is larger, wild animal, can run extremely fast (72 km/h), lives above ground. Rabbits, are those dumb, cute ones, you see in people's homes. Here's a interesting quote:Normally a shy animal, the European Brown Hare changes its behaviour in spring, when hares can be seen in broad daylight chasing one another around meadows; this appears to be competition between males to attain dominance (and hence more access to breeding females). During this spring frenzy, hares can be seen "boxing"; one hare striking another with its paws (probably the origin of the term “mad as a March hare”). For a long time it had been thought that this was inter-male competition, but closer observation has revealed that it is usually a femal…
