This isn't software per se, but it is IMHO, a decent looking set of ebooks on Coding and Programming of software. Along with performing better at your current IT related job. And/Or making the move into the arena of IT related jobs out there. If you are so inclined to do so.
As usual with Humble Bundle, a donation [payment?] of $1.00 gets you the 1st level of books. An $8.00 or more gets you the 1st AND 2nd levels of ebooks. While $15.00 or more gets you access to the entire collection. Levels of the 1st, 2nd and 3rd sets of ebooks [The whole enchilada].
While not for everyone, myself I've normally found enough value in a few of the coding/programming ebooks, so as to purchase the entire collection with the $15.00 or more price tag.
