Neat data visuals. Especially the networks of letter tpancisions when words change spelling, I never saw this idea expressed before. I showed this article to my friend and he got mad at me, he was always correcting poor souls on evil of eXpresso ;-)


Another neat FB analysis:

The Wolfram Cloud sandbox

and raspberry-pi

editions are free. I understand - low power - but still one can at least try it out.

"Inspired by the biology of a fly, with submillimeter-scale anatomy and two wafer-thin wings that flap almost invisibly, 120 times per second, the tiny device not only represents the absolute cutting edge of micromanufacturing and control systems; it is an aspiration that has impelled innovation in these fields by dozens of researchers across Harvard for years."

Well, what a about detailed study? Quoting from abstract:

"Microsoft’s continuing inability to correctly fix errors is discussed. No statistical procedure in Excel should be used until Microsoft documents that the procedure is correct; it is not safe to assume that Microsoft Excel’s statistical procedures give the correct answer. Persons who wish to conduct statistical analyses should use some other package."

This is a funny sarcasm on the topic:

They are saying Excel - established data tool - is, in fact, dead for big data. And what else matters?


The problem is that still most data is not big; even worse, big data is often either small data presented in a very sparse way (logs for instance) or is being subsetted or summarised to fit in Excel :(
