Hi all

I'm a programmer in Windows OS and usually use C# or VB.NET and some skill in C++.NET and ISO C++.
No I want to learn more and more about Linux OS and now I want to know
about programming in this great OS.

Currently I'm using Ubuntu (8.04) and Mandriva 2008 Free Edition.
Now I want to know which distro is suitable for programming proposes?!

In linux world many many languages are available like Python and even Snow Ball (What???). Which language is better for Console (Terminal) based and GUI based applications?

please help me and tank you all!

Welcome to LQ!!

When you are programming, you are using a set of tools including the compiler, libraries, and maybe an IDE. I'm not sure why it would make any difference what the distro is---once you are in a terminal, Linux is Linux.

Languages are pretty much independent of the OS---e.g. you can use Python in Windows, and you can program in C on just about any platform.

I recommend this book as a good starting point: "Beginning Linux Programming", 3rd edition, from Wrox. It will be on Amazon and--depending on your location--at the larger bookstores.

tanx and I think it's great start point for me!

Slackware. If you do a full install you'll get: C, C++, ObjC, Ada, Java, Perl, Python, Ruby, Tcl/Tk, and probably a few more I can't remember at the moment, plus loads of libraries.

What you say is principally true. However, some distros make it easier to do development work by having a richer set of tools pre-installed. This can run the gamut from compilers and various interpreters, to IDE's, to development oriented libraries, to other developer oriented support tools such as debuggers, source code revision management systems, etc.
I, too, would like to hear peoples' experiences with respect to what distributions are most helpful to programmers. I've often wished for the one true programmer's distro that had everything, right out of the box.
Having said this, I just installed Fedora 9, and after a cursory inspection, it seems very well equipped. I was able to install Netbeans, and it actually worked correctly without having to muck around with getting some bigger better faster strong version of Java installed first.
I frequently encounter things on the net which make me want to explore various programming environments (for lack of a better term). Perhaps it is a support library for some particular purpose, maybe a developer's tool of some sort, or some kind of GUI/widget set. As often as not, the prerequisite to trying said tool/library/language/whatever is a long road toward dependency hell. As a result, I often don't bother to try out the object of my interest. If a distribution were available that emphasized pre-installation of the richest possible set of these things, in a way that consistently works as expected, I would quite likely make it my distro of choice.
If anyone is out there looking for a niche market in Linux distros, that would be my suggestion.

Ubuntu is very good but not for pro users.
Mandriva and Debian are very good.
I'm using mandriva and I'm really happy with it.
