* "Scala books":http://www.scala-lang.org/node/959
** Programming in Scala, 1st edition is "free":http://www.artima.com/pins1ed/

You can find some helpful Git resources here:
* "Pro Git Book":http://progit.org/
** Available in "HTML":http://progit.org/book/, "pdf":http://progit.org/ebook/progit.pdf, "mobi":https://github.s3.amazonaws.com/media/pro-git.en.mobi and "epub":https://github.s3.amazonaws.com/media/progit.epub
