The illustration on our cover is of a Hercules beetle. These beetles are among the largest in the world. They are also, in proportion to their size, the strongest animals on Earth, able to lift up to 850 times their own weight. Needless to say, we like the association with a creature that has such a high power-to-weight ratio.
Here is a description of the Haskell language from the Haskell web site, with links to chapters from our book and to other sites.
Haskell is an advanced purely functional programming language. The product of more than twenty years of cutting edge research, it allows rapid development of robust, concise, correct software. With strong support for integration with other languages, built-in concurrency and parallelism, debuggers, profilers, rich libraries and an active community, Haskell makes it easier to produce flexible, maintainable high-quality software.
