The introduction to Reactive Programming you've been missing

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

Getting Started with NPM (as a developer)

If you haven't already set your NPM author info, now you should:

npm set init.author.name "Your Name"
npm set init.author.email "you@example.com"
npm set init.author.url "http://yourblog.com"

npm adduser

$ brew install selenium-server-standalone chromedriver
$ git clone git@github.com:theintern/intern.git
$ cd intern
$ npm install --production
$ ln -s .. node_modules/intern
$ curl https://gist.github.com/neonstalwart/6630466/raw/f0e4e4efbefa40c746f7c68e2bb4fa0dd5215047/selftest.local.intern.js > tests/selftest.local.intern.js
$ java -jar /usr/local/opt/selenium-server-standalone/selenium-server-standalone-2.35.0.jar -p 4444 &
$ node node_modules/intern/runner.js config=tests/selftest.local.intern

Install ImageMagick (>= 6.8.0-10) for image conversion:

brew install imagemagick

Install leptonica (>= 1.69) and tesseract (>= 3.02.02) for OCR:

brew install leptonica
brew install tesseract --all-languages

Or install without --all-languages and install them manually as needed.
