Are there any free online tools out there to make visio kind of diagrams. I would like to practice my flowchart skills. Are there any good sites or books or articles out there that discuss best practices for flowchart diagrams.
Dia is an open source option:
http://projects.gnome.org/dia/
+1 for Dia. It's also cross-platform, which won me over. Another advantage of Dia is that the diagrams are stored in compressed XML.
I had a project where I needed to diagram something in the database, and I was able to write a program to create Dia-compatible XML from the database, which saved me a HELL of a lot of typing and drawing. I just had to reposition and resize the objects.
Already answered here;
Here is some:
StarUML - http://staruml.sourceforge.net/en/ (Free)
Enterprise Architect from Sparx Systems (Not free)
Violet
Umbrello UML
ArgoUML
Dia
Here is a complete list of over 50 UML designer (free and not) Wikipedia list:
http://en.wikipedia.org/wiki/List_of_UML_tools
There is a great multi-platform software that for some reason no one mentions but its really worth a try:
yEd: http://www.yworks.com/en/products_yed_about.html
Open Office includes a program called Draw which is really nice.
http://www.umlgraph.org/
Found no other better solution. Program your charts.
Makes beautiful sequence diagrams.
lucidchart is an online, collaborative tool with flowchart features.
Gliffy is an online flowcharthing program.
Personally I use Dia, an open source Visio kind of clone (it works under Windows, Linux and MacOSX).

I'm looking to start developing Linux, specifically graphical elements and visuals. For example, the gnome-panel. I would be developing graphical interfaces like that. So the question is, what do I need to know? What resources do I need? I've looked all around for resources and I've discovered qt (of course) FVWM, and looked through an archived version of lynucs.org. So, what should I begin with? I haven't found a single tutorial on creating graphical elements for linux, so hopefully someone here can help me.
Thanks.
In Qt you have a very good documentation. You can start with some easy tutorials and than work on with more advanced concepts.
Here is a good starting point: http://qt-project.org/doc/qt-5.1/qtdoc/gettingstarted.html
If you are looking to develop desktop components that integrate with Linux desktops, then the answer is not straightforward. Depending on the desktop environment you develop for, you have to use different libraries.
If it is for Gnome, then definitely look into GTK+, or more recently Javascript.
If it is for KDE, then you should use Qt, as KDE is written entirely in Qt.
For working on gnome-panel (or some other GNOME component), you could look into GTK+.

I'm searching for a consultation, or maybe an opinion, a suggestion, or something like this.
I'm starting a project (desktop application) that is something like an IDE for writing books/reports. I'm planing to introduce LaTeX features, if I can name them in a such way.
So the question is: Is it possible to integrate a LaTeX script or plug-in in my software in order to have the needed features?
Waiting for questions or suggestions on my topic.
Thanks in advance!
P.S. Sorry if this topic was already posted.
Not sure I understand your question correctly. I never heard of some kind of LaTeX library or plugin of some kind, which is readily available to be integrated in other programs.
You tagged your question 'qt' so I assume, you use Qt as your framework. The only way I see to integrate LaTeX into Qt is using QProcess. Write your LaTeX code, start pdflatex with QProcess. The question then is if you can do something with the created pdf file.
Look for MikTeX and TeXworks. If you google those, you should be able to get the links to download those. That should do what you need.

I find myself in the unique position of having to find a suitable 2D graphics engine (or 3D with easy-to-use support for 2D interfaces) for the creation of a simple, full-screen retail sales tool for my business. I have been considering the use of the SDL library after briefly reviewing its features. It seems fairly easy to grasp, and I have used it before long long ago, but before I begin my project I felt the need to consult with the greater community to make sure I was making the right (read: easiest) decision. One concern I have about the aptitude of SDL is its lack of native support for GUIs.
This is a major concern since my project hinges on the ability to implement some sleek radial menus and other custom widgetry (this is now a word) to ensure easy of use. This software will be running on a kiosk in my store and will serve as a sleek way to browse stock, even that stock which is only available online, and place orders. Am I headed the right way by using SDL or is there a better engine, or perhaps even language, that would be a more perfect fit? Speaking of, I know C++, Python and Perl so an engine or library native to one of those languages would be perfect. I chose SDL because of its hardware independence and C++ nativity. I would consider the use of Java but the system the application will be running on is restricted by corporate and cannot have JRE installed. This would be fairly easy to rectify if Java would truly be the best bet for this kind of application. Thanks in advance for all the help and please feel free to add personal experiences and opinions as much as possible.
Instead of SDL, go for QT. It is more feature rich and you can do the same (and much more) as in SDL.
This answer explains how to create full-screen windows, so that partially answers your question.
Another part of the answer to your question is this : you can create an opengl widget, in which you can do 2d/3d graphics, the same way you would do in an SDL window. For example like this

I need to put some 3D images into PDF files, and PDF uses Universal 3D (U3D) formats. I don't like the U3D Sourceforge project (basically what Intel released after the ECMA standardization effort).
Does anybody know of good U3D libraries I could use? I'm using C++ on Microsoft Windows, FWIW.
VCGLib is a mesh processing library that has a U3D exporter and a variety of importers (see http://vcg.sourceforge.net/index.php/Tutorial#File_Formats). MeshLab is a tool built on top of it.
Another answer would be Visual Technology Services with PDF3D (PDF link). I've started evaluating it and I like what I see so far.
I agree with your position of not liking the U3D sourceforge project. People at my company is having problems with it when exporting large models: it runs out of memory.
The project has explicitly stated that it has memory issues on its TODO list and is dead since 2007, so I strongly recommend you to go elsewhere.

Does anyone know a good resource or some pointers which could help me make a side scrolling tile based (descreet movement for character) with box pushing and moving platforms etc. I'm focused right now C/C++ console development (tho after this project I may stop and do stuff a little more graphical, still C/C++). Something bit like Super Serib Bros. I've taken a look at the code of SSB and I have some idea of how it works, tho the variable names aren't particularly helpful.
It occurs to me someone somewhere must have thought about his problem before. So before I go re-inventing the wheel, any clues?
You'd probably be best signing in one of the better known game development groups, for example GameDev or DevMaster as well as checking out the stuff Microsoft pushes.
I'm not sure how many resources you will find for making games, as most open source games develop their own tools and commercial games keep their tools private.
I think that the best strategy is to start from scratch, using existing low-level libraries.
For C++, I recommend using Box2d for physics and HGE for graphics. I have also heard that python's pygame library is good, but have not tried it myself.
I use a an editor/engine called RPG Maker for fun in my spare time. You can download the demo for free. It is a tile based rpg engine and is pretty basic, but the engine is written in ruby and can be browsed very easily.
