Yes, that’s a bold claim. But I stand by it. I’ll skip straight to the important part:
Intrigued? If you’ve already installed IPython (and numpy/scipy and matplotlib), you’ve already got it! Just start notebook:
$ ipython notebook --pylab inline
The notebook console will open in a browser window. (Ok, you might need a couple more dependencies, but how hard is that??)
Then all you have to do is download the notebook and drag it to the console browser window! How awesome is that?!
And, if that isn’t enough, a lot of work has been put into it’s multi-processing abilities. It is well worth the time to watch the introductory video.
