This is an interesting concept. It makes perfect sense to learn both simultaneously. On the other hand, it must be confusing at times. Imagine learning two languages at the same time, from the same book. It's an experiment I haven't tried, but i'm curious about the outcome.

Also interesting to learn two languages, in parallel, where neither is particularly good at parallelism :)

Are you trolling right now? R's idioms for parallelism are pretty darn straightforward and easy to use. Effective too.

What makes you think R or Python are bad at parallelism? My experience is that both are very decent.

[tyingq]

Both have packages that can manage subprocesses. Both have inherently single threaded interpreters.

[rpier001]

What technology in what language are you comparing them against?

[nurettin]

Humans are very good at doing things successively and calling it parallel.

I taught myself python by converting ruby programs using ruby syntax, coding styles, libraries etc. I just used the pick-axe book as a reference and converted code examples from any interesting and/or useful/relevant python source I could get my hands on at the time. (circa 2008?) So this actually makes sense to me learning 2 languages at once as long as you understand what you are doing with them to begin with. I would not recommend it to a beginner though. Interesting though. See it through and complete it. I'll check back.

I suspect a lot of readers will have some proficiency in either R or Python and want to learn the other.
