I'm writing simple console Pomodoro timer (as my Haskell learning exercise):
Until that time menu was based on the prompt line. But now I want to replace it with arrow-based menu, like in Yeoman:
How can I do it in Haskell?
I read about System.Console.Terminfo.Keys and other System.Console packages, but not found solution for my question.

One way to do that would be to use bindings to ncurses library. Infact ncurses shows you an example of handing the key character "Q" in their sample program.
Another nice Haskell solution is vty-ui which has got a nice documentation to it.

I wrote a nice program in linux and I don't want people to steal my work, is there a way for me to hide the contents of my sh file from other people seeing it when I publish it? And it still has to be functional when I publish it to the public. I won't be posting any of the code because of this.
You could consider adding an open source license to your program to protect it:

One possibility is to compile the shell script to C and ship a binary executable. Compilers for the shell language exist, such as CCsh from Comeau Computing, which is a proprietary product, like yours.

How do I create a window in OpenGL on Linux instead of using GLUT? Is there a performance penalty when using one or the other?
First of all, i want to ask if using glut is performance-wise.
It makes no difference for OpenGL performance, which framework you use to create the window.
How can i do it?
You mean the long and hard way using X11 and GLX? I've example code for that here:

Suggestions for writing a programming language?
I have used many programming languages and after several years of experience I have finally decided to make a language with my friends. I know that this is a task not for the faint of heart. We are devoted to the task and are going to make sure that this gets completed.
Now I wanted to start off by asking: what are the steps to writing a programming language? What should we start off with (ex. The parser)?
Any answer is helpful!
If this is your first language, then work on all parts of it at the same time, start with a mini language spec and extend it feature by feature. Unless a its a domain specific language you should use a language that comes close to what you try to implement so that later you might be able to write a conversion tool to get a bootstrapping version of your compiler.

Are there some more Text User Interface (TUI) frameworks for bash (other than this)? : http://code.google.com/p/bashsimplecurses/
I want to take user input (data entry)
process the entry
If all you need to do is prompt the user for information, take a look at dialog.

bashsimplecurses is pretty capable (from the little I've seen), but you might want to try GTK Server. (Have a look at the docs page for tutorial and manual links). It can work with a large number of scripting languages. Other Stack Exchange users (particularly the UNIX/ BSD/ GNU/Linux lot) recommend using ncurses with Python.

I'm missing the sort generic traversal and transformation libraries that I have in Haskell when I'm working in F#.
Has anyone looked at doing something like Uniplate/Biplate for F#?
There's a brief mention in the comments of one of Neil Mitchell's blog posts, but I never found any further development:
http://neilmitchell.blogspot.com/2008/09/general-updates.html
I imagine you could build something on .NET reflection instead of type-classes, but I don't want to dig too deep without looking at prior art.
