Do you know some open source, or just free software to drawing SADT diagrams?
You can try out Ramus
They offer Educational version, free for non-commercial purposes.
The Dia program can do (https://wiki.gnome.org/Apps/Dia).
Can be used on Linux, Windows and MacOS.

I need to know if ROS can work with all kits? or needs specific requirements?
I mean, can I buy any kit and control it by ROS?
If yes, is there any needed chip, ports, or connectors?
Thanks in advance.
You should use http://answers.ros.org/questions/ for questions regarding ROS, but yes, it is in general robot-agnostic.
No, not all robots. Only robots with X86 or ARM hardware that can run Ubuntu Linux.
There are also experimental versions of ROS for OS X, Gentoo Linux, Arch Linux, and Android (NDK)
When choosing your hardware platform, consider ROS support for various sensors and actuators, as well as the library of packages that add other capabilities.
Here's a very long list of robots that use ROS.
Given the availability of a new workstation (Intell Xeon X5690, Windows 7 Professional, 64-bit) for numerical analysis of fluid dynamics models, I find it a shame not engage in parallel computing. So far, I have had no or little experience in this field.
What's the difference between MS-MPI and the latest release of MPICH suitable for Windows? I installed MPICH 1.4.1, but I cannot get a test program to work on Ifort. How am I supposed to compile the program? Do I have to change Ifort configurations somehow to add the libraries of MPICH? Isn't there any good manual available online that could meet my needs?
There's lots of questions in this one question, but it all boils down to one basic question: How do I install MPI on Windows?
MPICH has long since worked on Windows. The last version that supported it was 1.4.1p1 as you've found, but it doesn't have any support anymore from the MPICH developers so if you have trouble, you probably won't find much help. I haven't seen anyone on here step up to help with those questions so far.
MS-MPI is a good option if you want to use Windows. It's free to use and still has support directly from Microsoft. You'll have to read their documentation about how to set everything up correctly, but it's probably the right place to start if you want to use MPI on Windows.
Intel MPI also works on Windows, but it isn't free so you might not want to look at that right now.
Well, I need your advice.
I'm working on a huge engineering project, everything is ready now (resources and formulas etc) and it's time to start coding. I don't have any problem with what language to code with (i know a lot).
but they're the users who are pulling me off.
I use Windows as a primary OS but there are a lot of Mac and Linux users too. And these days tablets have taken a lot of developing space ( Android and stuff).
So what option do you advice :
1)Write the program from the scratch on each OS, I mean writing the program on Windows using Visual Studio, on Mac use Xcode.
but this costs a lot ... I own Windows PC, buying Mac or Mac OS for my desktop, will ruin my budget.
2)Use cross-platform compilers ...
It is nice. but how about the commercial use? I have read that I need to buy a commercial license in order to publish my apps worldwide.
please if this is wrong tell me about it.
so really I don't know ... shall I just deploy it for Windows?
Also if you know a great option for cross-compiling would help a lot .
Your Advice Is Appreciated
Best Regards
What kind of app is it?
If it's just a number crunching app with a very simple front end then can you write a commandline version and wrap it with a web script?
If it needs very responive rich user interface and you can program in C++ then Qt is a very good solution even if you don't need cross platform.
The LGPL license is perfectly suitable for commercial apps.
I'm in the research phase of my next computer build. I have the idea in my head of running a hypervisor as the base of the system, but i would want to be able to take a shot at programming opencl with one of the OS's installed on the hypervisor...and maybe some gaming. Would i have enough access to the GPU to be able to achieve this effectively, or am i better off installing an OS that i will do development(and gaming) from and then just virtualize any systems on top of that?
what are your recommendations for a hypervisor, vmware, microsoft or other?
sidenote: Recently graduated with a BS in CS, the massive parallel processing seems like a good idea of something to learn, won't be doing any 'real'/major development work. also, i'm aware that CUDA is more mature in it's development, but i'm sticking with opencl for a few reasons, so please don't try to persuade me.
thanks for your input!

whats your focus? Virtualisation or OpenCL?
Hak5 did a nice walkthrough of debian based virtualisation environment ProxMox, but I don't know whether it allows virtual hosts hardware access or OpenCL virtualisation.
This question is for experienced Unix/Linux developers.
If you have found that you like Mac OS X better than *nix as a development platform, why is that?
I know that hardware configuration is more convenient and graphics are generally more polished, but I'm not referring to those things. I'm asking specifically about functionality related to software development.
Also, do the benefits still apply if you are mainly targeting Windows or Unix/Linux?
For most purposes, OS X is Unix. Aside from Xcode (which I personally don't care for), there isn't really anything there to make it better or worse than any other Unix-like system for development.
Most of the typical tools, libraries, languages, and interfaces are there, you'll even be using GCC for C/C++ work. As long as you're not developing against Apple/OS X-specific interfaces like Cocoa, you are developing on Unix.
I use OS X because it just works, thus not interfering with my development, not because it has magical fairy dust that makes it better than any other Unix for development.
I love Apple as a dev platform because I get all the power of the *nix commandline as well as Apple's developers tools (XCode).
The additional software/hardware polish, and quality of third party software make it all that much more enjoyable.
Mac OS X is not better than a Unix environment, it is a Unix environment: http://www.opengroup.org/openbrand/certificates/1190p.pdf
I'd go as far as saying it's probably the most used Unix, considering it's also in all iPod Touch and iPhones.
(As far as I'm aware, Linux isn't a certified Unix, but I may be wrong, perhaps a distribution/vendor went through that process.)
Sometimes, for professional reasons, you just have to have tools that are compatible with what your boss or customers use. This often includes proprietary tools like MS Office, whether you want it or not (OpenOffice can't always deal perfectly with Word documents). OSX provides this intermediate ground, where the developers can also be users or closer to their user base.
