- Transcript of Tim Berners-Lee's Keynote Session at JavaOne, May 1996, San Francisco, California, "The Axes of Revolution". Discusses (web-like) features of Java that make it more than just another language: language, bytecodes, class library, RMI, emphasizing the need for independence between such features. The talk touches on a range of topics, but I find most telling to be the depth and breadth of vision, back there in 1996 when the Web was starting to be widely used, with respect to the Semantic Web, Web of Trust and related matters. http://java.sun.com/javaone/javaone96/TimBerners-Lee.html.

- Papers exploring the advantages of functional programming
- Why Functional Programming Matters, John Hughes: linked from http://www.math.chalmers.se/~rjmh/Papers/whyfp.html. This gives some strong indicators why one might choose a language like Haskell, which in turn suggests styles of programming that best leverage Haskell's strengths.
- Scrap Your Boilerplate, Ralf Lammel and Simon Peyton-Jones: linked from http://www.cs.vu.nl/Strafunski/gmap/. Even though it describes features not yet present in standard Haskell, this serves as a continuation of the John Hughes paper, suggesting the kind of coding advantages one might seek to gain from a functional language like Haskell.
- Haskell vs. Ada vs. C++ vs. Awk vs. ..., An Experiment in Software Prototyping Productivity, Paul Hudak, Mark P. Jones: http://www.haskell.org/papers/NSWC/jfp.ps.
- "It is significant that Mr. Domanski, Mr. Banowetz and Dr. Brosgol were all surprised and suspicious when we told them that Haskell prototype P1 (see appendix B) is a complete tested executable program. We provided them with a copy of P1 without explaining that it was a program, and based on preconceptions from their past experience, they had studied P1 under the assumption that it was a mixture of requirements specification and top level design. They were convinced it was incomplete because it did not address issues such as data structure design and execution order."

- Monads - an aspect of Haskell that is at once very easy to use and bewilderingly subtle to master. Papers I have found useful include:
- Haskell language extensions. There are some small, commonly implemented extensions to the "standard" Haskell-98 language that significantly add to its expressive power:
- Hierarchical modules: http://www.haskell.org/ghc/docs/latest/html/users_guide/syntax-extns.html#HIERARCHICAL-MODULES
- Multiparameter type classes: http://www.haskell.org/ghc/docs/latest/html/users_guide/type-extensions.html#MULTI-PARAM-TYPE-CLASSES. See also Type classes: exploring the design space, Simon Peyton Jones, Mark Jones, Erik Meijer: http://research.microsoft.com/~simonpj/multi.ps.gz
- Type classes with functional dependencies: http://www.haskell.org/ghc/docs/latest/html/users_guide/type-extensions.html#FUNCTIONAL-DEPENDENCIES. See also: Type Classes with Functional Dependencies, Mark P. Jones: http://www.cse.ogi.edu/~mpj/pubs/fundeps.html. These are used by the Monad transformer library functions that ship with GHC.
- Rank-2 polymorphism, and higher rank polymorphism: http://www.haskell.org/ghc/docs/latest/html/users_guide/type-extensions.html#UNIVERSAL-QUANTIFICATION.
- Generics: this isn't yet what I'd call commonly implemented (the type mechanisms are beta in GHC 6.0), and involves a combination of a "type enquiry and interpretation" mechanism (called "type cast", but I think that's a misleading name), and rank-2 polymorphism, mentioned above. The ideas are described in Scrap Your Boilerplate, Ralf Lammel and Simon Peyton-Jones, linked from: http://www.cs.vu.nl/Strafunski/gmap/.
- "Existentially quantified" data constructors: http://www.haskell.org/ghc/docs/latest/html/users_guide/type-extensions.html#EXISTENTIAL-QUANTIFICATION. This is a device that allows a data constructor to package some related values with differing underlying type components into a single type value. I'm still not entirely sure why "existential". This appears to be syntactically related to Rank-2 and higher order polymorphism, but I haven't yet figured if it really is.
