Linear Partial Differential Equations and Fourier Theory
Complete textbook by Marcus Pivato on the solutions of linear partial differential equations, with emphasis on eigenfunction methods (and hence, Fourier analysis). Lots of pictures.

Essence
A generator for LR(k) and SLR(k) parsers in Scheme. The generated parsers perform error recovery, and are highly efficient. They result from the general parser by an automatic program transformation called partial evaluation. This guarantees consistency and ensures correctness. However, no specific knowledge of partial evaluation is required to use Essence. From Michael Sperber [Mr. Preprocessor] and Peter Thiemann.
