Many of the Manga guides are good. Biochemistry is the best (http://www.amazon.com/Manga-Guide-Biochemistry-Masaharu-Takemura/dp/1593272766). The statistics one is good too but probably a little beyond most bright 10-year-olds. An interesting math book is Math Girls (http://www.amazon.com/Math-Girls-Hiroshi-Yuki/dp/0983951306) - it sort of has a plot but its more math than story. There are some good kids programming books like Python for Kids ( www.amazon.com/Python-Kids-Playful-Introduction-Programming/dp/1593274076), or Scratch Programming (www.amazon.com/Scratch-Programming-Adventure-Covers-Version/dp/1593275315). Speaking of Scratch, it is really great if you haven't already checked that out (https://scratch.mit.edu/). Its free.

New Hampshire is small, rich, and privileged. It has nothing to do with your relaxed gun laws. The "stricter" gun control in NY and CA is a joke compared to what it should be.

Please fix that extraneous apostrophe.

It doesn't take anywhere near 500,00 workers to build those phones.

Overestimated?

If the math is more abstract, then Sage (python-based) is a better bet than R (and Sage includes R): www.sagemath.org.

I teach college students, and almost all of them are hopeless at programming. This is at least partly because they have never seen a CLI. I'd like to see more CLI used (yes, required!) not less.

I don't like Perl so I wish the catchy put-down of the summary title was accurate, but its not quite right. I think shell scripts are the COBOL of scripting. Perl might be more like B, although I'm not sure there is a great analogy there.

No. This is a fraud, and by sending these jokers any money you only encourage more fraud in the future. At most it might make sense to try to replicate their results, but please don't give the perpetrators any money.

That's quite a Byzantine method of obfuscation.

Sage is an open source platform for mathematics and computation that ties together many C and C++ libraries with Python code. You could browse the project bug and enhancement tracker or the sage-devel google group for some ideas of where to contribute and the project culture. There are a very wide range of things to do. With Sage, and probably most other projects, a very good way to get started is to help improve the documentation. This is not glamorous, but it is effective. It involves you with other people in the project, and gets you familiar with their development practices. Its usually well appreciated since documentation quickly gets out of date on an active project. Writing documentation will suggest some coding projects naturally - to adequately describe a current bug to users, for example, you will have to understand it somewhat, and that might suggest a solution.

That is too true man. I have recently been in a world of pain from not properly documenting output from simulations.
