It seems like whenever I try to figure out how to use a piece of Java code, the functionality is spread out over a huge collection of classes and methods so that it is impossible to figure out where things actually happen and how the code is supposed to be used. Am I correct to perceive this as a general trend in Java, or is it just the projects that I looked at and/or my lack of experience in how Java sources and libraries are organize? Yes I had a bit of a rant about that in my blog recently http://gaiustech.wordpress.com/2010/09/27/api-documentation/ It's by no means only Java; automated documentation generators are the problem. They add no more value than a smart editor could give you anyway, or reading the comments. You need an API reference *and* sample code *and* a high level introduction and explanation of intent to count as documentation in my book.

Re: [Haskell-cafe] help me evangelize haskell.
My usual rhetoric is that one-off, throwaway scripts never are, and not only do they tend to stay around but they take on a life of their own. Today's 10-line file munger is tomorrow's thousand-line ETL batch job on which the business depends for some crucial data - yet the original author is long gone and no-one dares modify in case it breaks. So it is just good sense to use sound practices from the very beginning. One of the features of Perl is that it will try to work even if you make type errors (e.g. give it a scalar in place of a list, or a string instead of an int). One day, however, it WILL fail. Haskell finds these types of bugs upfront, and not when your pager goes off at 3am...

Re: [Haskell-cafe] Why does ghci recompile the module compiled in different OS ?
Are you trying to use the .o compiled on BSD on Linux? They are two different operating systems. So the Linux ghci isn't using the .o, it's using the .hs.
