I've recently come in contact with a proprietary descendant of UniVerse. Does anyone know where I can get a good tutorial or brush up on the syntactic quirks of its more popular parent? I can't figure out how to even get a table listing. Navigating my way around is difficult, and I don't see any man pages.
UPDATED with the official Rocket Software links:
Special attention needs to be given to SQL Reference, SQL Administration for DBAs, and User Reference. There is also a link at the bottom of both of these pages to a zip with all of the docs. There is also a demo on Rocket Software (personal information required) for Universe 10.3, but it only works with RHEL. And, even though it is statically linked it segfaults for me using Ubuntu 8.10.
These links are official from Rocket Software (current owner of Uni* line of products)
UniVerse 10.3 Demo latest
Guide to installing it on Ubuntu 9.10
UniVerse 10.3 Documentation latest
Supporting whitepapers and theory
Manual index page Servers & Tools
Here is one that predates Rocket Software's aquisition of the product line:
Old IBM ftp repository of U2 stuff
IBM ZIP of 10.1 Documentation

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 I have looked at several on the net but seems like a lot of them are out of date or the development stopped.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 have been recommended to use the Microsoft project as a project manager in my course. But being a opensource fan and linux user what will be the best opensource alternative to this.
I have seen this question: https://stackoverflow.com/questions/109579/open-source-alternative-to-microsoft-project, which suggests to use openproj. Openproj's last version was released 2 years back so I was thinking otherwise.
Also following the wiki project management softwares comparison, I found out there are lot of opensource alternatives. Some software in the list with maximum features I found out are:
Endevour
eGroupWare (web based)
Onepoint Project
Project.net
Project-Open
Redmine
web2project (web based)
Could anyone recommend what is the best (or most popular) alternative.
Update
Finally looking at the various project management softwares, I found out that deciding for one completely depends on your needs. The one thing that works everywhere is Pen and Paper as suggested in this answer.
Your list is missing my two favorites:
Pen and paper
.txt files
and I don't mean this in jest! They are simple tools - but they have certain advantages to them. They have limitations in what you can track with them, and hence you only track what is important. Take it as the minimalistic approach to project management if you will.
In general, I don't tend to think you can manage software development by GANTT or PERT and resources. Most software construction is creative and implements things which have not been tried before. Hence, the problems you are to solve have a high risk of failure where you have to retry the attempt. I find that GANTT and friends are best if you have a large number of well-known low-risk tasks to accomplish.
You may not believe this to be true, but then I implore you to at least take my standpoint into consideration when you track the project in detail. Especially if and when you suddenly have to update the GANTT chart due to slips.
Have a look at RationalPlan. It has different editions based on your needs:
http://www.rationalplan.com/download.php
http://www.openworkbench.org/ is what we are using
Another option is Gantt.

Many Product Managers use wiki's or bug tracking software like Jira but there must be a better solution. I would love to get your feedback and suggestions.
I'm happy with Word. I don't think it's the tool that matters as much as the process, or how the tool is used.
Mockup tool to clarify requirements together with users
Word to create "formal" documents
Some mockup tools can get pretty close to producing the "spec" for developers, too. MockupScreens for example (I am developer):
http://MockupScreens.com
EDIT: Oh, and on a big/formal project you might really need a traceability matrix (you can use Excel for that, or some specialized tool like RequisitePro). You know the situation I'm talking about: there are hundreds of "stakeholder request" that need to somehow be mapped onto "functional requirements" to 1) prove that each request is addressed and 2) to do regression checks when something somewhere changes
We use Word + Balsamiq mockups (www.balsamiq.com).
If you deliver Web or desktop applications, and the users need help specifying their needs or the desired visual layout, a mockup is fundamental.
Also, Balsamiq uses a lightweight wireframes style that will help your customer to focus on the information, and not in the graphic details (fonts. etc.)
We track the state of each requirement in a version controlled Excel file.
Since this post is tagged 'agile' and you framed your question as how you should write and communicate product requirements, I'd say the most common tools used are user stories and conversations.
You mention Jira and wikis, so it seems like one thing you're looking for is a requirements repository. Those are great to have, but don't forget that within most agile frameworks those requirements artifacts are merely placeholders for a conversation. That conversation is the primary requirements communication mechanism for most agile teams and no tool or application can completely replace it.

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.

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 Håkan 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
