Sedgewick's Algorithms book is great for practical learning but too tied to Java and implementation details. It is a bit shallow on theory, though the community and resources for other languages help.
That said, I personally prefer Introduction to Algorithms (CLRS) for its formal rigor and clear proofs, and Grokking Algorithms for building intuition.
The broader goal of this project is to build a well tested, reference quality set of implementations in C, Python, and Go. That is the next milestone.
Possibly you mean "too tied to Pascal" ;-)
