I started an interesting book on DSP for dummies (engineers like me) and I would like to see what we can do. www.dspguide.com. I like that he does not focus on math for their correctness.

Getting Pharo to Mars?

by phil＠highoctane.be

Given http://waitbutwhy.com/2016/09/spacexs-big-fking-rocket-the-full-story.html we should find some way to get Pharo into it somehow. Anyone having ideas on how to do that? Phil

Doesn't mean we can't be different. One thing though is that the typical function is what newcomers would search on, which makes me consider it could be useful in Spotter to have a mapping from functions in other languages to Pharo methods. So a user would type stdev and the top hit would be standardDeviation.

https://en.wikipedia.org/wiki/Standard_deviation says In statistics, the standard deviation (SD, also represented by the Greek letter sigma Ï or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.

No this is my initials. I should have copyrighted them so may be we could have decent names.

Hi guys is stdev a typical name for standardDeviation? Because I found it sad to have mean and stdev instead of mean and standardDeviation. Stef
