Over the next five years, Carabos will be collecting donations and license purchases towards a target goal of 300,000 Euro. When the goal is met or the five years expire, whichever comes first, PyTables Pro will be released as Free Software, 10% of the raised funds will be donated back to Free Software projects such as NumPy, and the remaining money will sponsor the team's continued development of PyTables Pro as free software. PyTables Pro is a scientific-computation-oriented database that claims to search a table of 10,000,000,000 rows in the time it takes to perform a single disk seek."

In the intervening time, he has gone and done something about it. Introducing Hackety Hack, a simple Ruby-based environment that comes equipped with seven lessons (so far) that lead a beginner through the joys of programming the Ruby way. Lessons include building a chat client and a YouTube video downloader, all in an intuitive and easy-to-understand fashion. Interestingly, why has been testing and tweaking it for several months with a small group of beginners (and their kids) to make sure it flows as nicely as he intended it to."
