With Java, Groovy, and Python, it is easy to find the standard, complete, easy to navigate documentation for the language.
I'm starting to learn Haskell, and I'm not sure where to find this. In particular, it doesn't seem to exist at haskell.org.

If you scroll down on http://haskell.org/, on the left sidebar under "Libraries", you will find a set of documentation of all libraries (called packages), which might be what you're looking for. However, be aware that it is an extremely large database, because it includes user-submitted content as well as standard libraries.
The two online search engines "Hayoo" and "Hoogle" might be able to help you. You can search by function name, type signature, or both. As far as I know, the only difference is that "Hayoo" searches the entire database, whereas "Hoogle" searches the standard libraries plus a few common extras. I would recommend Hoogle, because it generally gives you what you want, and is in my experience more reliable.
While we're on the subject, I personally think that http://learnyouahaskell.com/ is a great resource for learning Haskell if you've never seen a functional language before.

http://www.haskell.org/ghc/docs/6.12-latest/html/

Sorry can't comment yet, so here.
Hoogle is not just online search engine. Check ghci integration.

I was just looking for the same thing:
Wiki: http://www.haskell.org/haskellwiki/Category:Haskell
Good Intro: http://learnyouahaskell.com/chapters
Not much help, but it's a start.

http://book.realworldhaskell.org/read/ is pretty good.

Give this a shot!

Currently we are using Lucene for our search engine, but we want to look at some alternatives. I have looked at several on the net but seems like a lot of them are out of date or the development stopped. That is why I want to ask if you guys know any good open-source alternatives to Lucene that are still in development?
Kind regards,
Merlijn
Try Sphinx search http://sphinxsearch.com/. It is used by many NLP researchers.
If you are looking for an open source and Java based alternative, then you could try Terreir. Note that Terrier targets academia.
If the language is not an issue, then you could look at Xapian. I found its community quite active, and it has participated in Google Summer of Code several times.
Otherwise, you could try Whoosh, a python based search library.
FastcatSearch is also open source and java based alternative.
Lucene is a IR library as already you know, Solr is a search server, and FastcatSearch is a counterpart of Solr.
It provides web-based manager, so that you can set up configs easily.

I am looking for an equivalent software to Dreamweaver in Linux.
It is not an exact match but it is based out of Eclipse which means super cross platform funky java love.
http://www.aptana.com/
Aptana Studio is actually what I replaced Dreamweaver with since Adobe bought Macromedia, I use it on Windows and Linux without trouble. But for the suggestion you will also get my 2 cents about Wysiwtf... it is almost never what you get. Some of the best code I have ever done in my life was done in SciTE (also available in Linux), it supports multiple coding languages and offers enough features to be useful without becoming bloated.
If you want something reasonably non-technical, then perhaps Kompozer?
Or, if you want more technical stuff, then you probably want Aptana.
Another mention bluefish.
Depending on what desktop environment you use I can recommend Quanta+ to you. It's part of the KDE SC but can also be used in other DEs.
You could also use KompoZer, it seems to be nice as well. Didn't test this one though.
I've also researched this for myself, and the answer is that, in my opinion, there is nothing comparable.
Most people choose Dreamweaver for its WYSIWYG (as good as it can be with HTML), and the ease of use. If you're looking for database connectivity, PHP debugging and the like, then Elipse beats Dreamweaver by a lot, but chance is the original poster is looking for the ease-of-use, so neither Bluefish nor Eclipse is going to satisfy him.

I'm completely new to XML Schema, XML Stylesheets and XQuery.
To me, XML is just a text file just containing tags and values. I know that much, lol.
I just got a homework asking us to design simple XML Schemas, and also applying Stylesheets and XQuery.
Could anyone please point me to:
"Best" books/resources (based on your experience) that would teach me XML Schema, XML Stylesheet, and XQuery. (Would be awesome if it's example-driven since I learn best by doing).
What development environment (IDE, tools) that would allow me to solve the homework in the most productive way.
I know it's a school assignment, but I want to do the assignment like how professionals do it so I can gain a lot from the assignment.
The best place to learn about XML schemas is the W3Schools site.
Same for XSL-T stylesheets.
Go to the source for jQuery.
I think IntelliJ is the best IDE for this, but that's pure Java. The community edition includes XML features, but I'm not sure exactly what you're after. XSL-T is best done by hand the first time.
I was looking around on Stackoverflow, and came across this post. I like the suggestion of the post's chosen answer. I took a look at the book on Amazon, and its table of contents seems to show me the application of XML.
This book is probably is also good. Seems like it walks you through XML design.
Also, this book also covers tools! (check the table of contents)
Okay, as for the tools, these probably could do (each website also has resources (videos/tutorials) on how to use their tools)
Stylus Studio
oXygen
Altova

I am collecting logs from several custom made applications. Each application has it's own log format. What I'm looking for is a central tool which would allow me to search through all of my logs. This means the tool would have to be able to define a different regex (or alike) for each log file (marking where a record begins, ends, and what are the fields). I've been trying Splunk, but I'm not happy with it, since performance are slow, I'm limited (free version) with the amount of indexed data per-day, and it's not as flexible as I want it to be.
Could you recommend a software (preferably free or cheap) for the task?
You can try Lucene. It is free. It is written in Java, and it allows full-text search over large amount of data. It is not a complete application, but rather a library, so you have to write code that uses it to index and to search your logs. You may have to define different document types or at least different indexing functions for your logs, but then search works beautifully.
If you can use Windows, try out Microsoft's best tool ever, Logparser. I wish there was such a simple tool for Unix. But there isn't. And although I've kept wanting to get around to making a Unix version of Logparser, I just haven't had the time.
Note: This would be a great project for someone with time on their hands or for a grad-student somewhere!

Never used it, but have heard of it.

Looking for tips, tutorials, books and other resources to get started with Constraint Programming.
There is a lot of excellent material available on the web once you get in the groove, but the links below are (IMO) good starting points (the ones I used).
Programming with Constraints: An Introduction - (Course website)
Programming with Constraints: An Introduction - (Google book)
Online Guide to Constraint Programming
Constraint Handling Rules (CHR) is a language to develop own (problem specific) constraint solvers. Check this:
CHR Homepage
There you find links to
WebCHR Online Demo (originally developed at LMU Munich, now beautified at Uni Ulm)
Several implementations for Prolog (naturally) and Haskell, as well as a (unfortunately unmaintained) prototype for Java (JCK).
There is also a JavaScript implementation of CHR: http://chrjs.net (https://github.com/fnogatz/CHR.js)
Maybe you can have a look at an introductory course thought at the Saarland University about constraint programming. They do not use mozart as dr_pepper said but Gecode. Gecode is a follow-up language of mozart, implemented partly by the same people.
I recommend getting started with mozart. It is an open-source constraint programming language and the site has plenty of documentation that will get you started.
Here is another link to a course website on Constraint Programming.
Earlier the course used Mozart/Oz for the assingments but it has now been replaced by Gecode.
I suggest you look further in the following website on constraint programming maintaned by HÃ¥kan Kjellerstrand (a.k.a Hakank) at Hakank's Homepage
Microsoft's Solver Foundation has some easy-to-understand examples.
The handbook of constraint programming is well thought of.
In trivia, my supervisor from fourth year university (which was a while ago now) is referenced there. :)
If you're a Java programmer, I recommend using Cream: Class Library for Constraint Programming
