Finally I got some time. The school is so boring but needs to be attended. I'm back with a small article that explains the use of the P/Invoke routine for the Mono Environment. In fact, it's only the introduction (I'll try to write a second and a third articles about other features and properties of the routine).
Also I got the "Introduction to Algorithms" book from Thomas Cormen; I really think it's a good book.
BTW: You can check the article (which I sent for the Linux Gazette yesterday and hope to be publicated) at http://dev.cu.buap.mx/carlos/reminder/pinvoke.html
BTW2: Somw weeks ago I began to wrote an small toy in gtk# that takes some files that include phrases and print one of them randomly ... also it receives a file and writes how much days left for that date. You can check it at http://dev.cu.buap.mx/carlos/reminder ... don't expect a big application, I wrote it in 8 about hours ;)
