More on Wolfram CDF

Wolfram's blog has a long post on Computable Document Format (CDF) which explains it nicely.  Now experimentally built into WolframAlpha.   The idea of having a computable document is very appealing.  You have a document and adjust parameters in the document and recompute other numbers or  visuals on the same document.  The document becomes computationally alive.  Available forWolframAlpha via a free plugin.  I do hope its usage takes off.    Details on the post:

" .... Two weeks ago we made a major announcement: building on technology that we’ve been developing for more than 20 years, we released Computable Document Format (CDF). I think CDF is going to have a big effect on the way all sorts of things can be communicated. Because for the first time it makes it practical to include live computation as a routine part of a document. There are many important applications of CDF that we’ll no doubt be seeing over the months and years to come. But today I’m pleased to announce an experimental one from us: Wolfram|Alpha with CDF.   ....  "
