From the website:
Welcome to langref.org. This is a repository of some standard programming situations you might encounter and their solutions in a variety of languages. There are currently 1598 solutions to 87 problems in 16 languages.
This is a small but interesting collection of programming problems with solutions in several languages. Well, small when compared to the problems found in Knuth’s The Art of Computer Programming. 😉
If you can stand the cries of: “why isn’t it finished yet?,” “why isn’t it more complete?,” “why doesn’t it cover X?,” etc., give me a poke if you would like to see something similar for semantic integration issues. For any semantic integration issue there are going to be any number of approaches, starting with: “Is this a problem you want to invest in solving?” If so, see step 2 (which will be various strategies with different costs and tradeoffs)
