A nice lecture explaining the infra needed to develop, maintain and release an R package [youtube https://www.youtube.com/watch?v=TER-rQoVs0k?rel=0]

I have always wanted to write Python code for cleansing real time data. Now that I have at least a working knowledge of R, I hope the transition from R to python would be a little easier as there are a lot of similarities between them. Drew Conway from NYU gives a brief 20 min. talk on the similarities and differences between R and Python. http://static.vcasmo.com/swf/vcasmo.swf

Dan Roam, the author of popular books “The Back of the Napkin” and “Unfolding the Napkin”, has written a new book with a message that one must fuse our linear wordy based thought process with pictures/images/visuals to comprehend things in a better way. Well, this message is not something new. Presentations with visuals catch our attention rather than the boring bullet point slides. To some extent my book summaries might also be boring as they are merely words, although I try to put in some visuals to make it interesting.

I was going over some old folders when I stumbled on to this mind map of the book “Calculus Gallery”. Indeed, a picture is worth a thousand blah blah blahs.
