Check out the video linked from the picture on this page here. It's amazing; I've never seen anything like it. A high voltage electricity substation generating a highly visible arc of electricity that grows to 3 storeys high before it disappears.
The page provides a full explaination for what happened; I sort of understand it. A bit.
For my current project I need a generalised way of processing mathematical expressions, so I've written a small RPN based expression evaluator. One side effect of this was that I wanted to look up a bunch of constants for my evaluator to support (pi, e, log2, etc).
In my googling around I stumbled across this page. It seems that Mr Y Kanada has calculated pi to 1,241,100,000,000 decimal places. That's one point two TRILLION decimal places. It took 602 hours of CPU time on a supercomputer with 1TB of memory.
Why is is that after looking at some words for a while they start to look really weird?
Right now it's just gone 5am and I've spent the last two hours working on some code to interface .NET code (C# in this case) to unmanaged C++. The only way to do this is via a managed C++ layer -- so I've written a library called ServerWrapper.
And right now, the word "wrapper" looks really, really odd.
This is such a cool project. People have submitted pictures for every minute of the day showing the time in a variety of weird ways, and the site will display them on a refreshing web page giving you a human clock.
