What is a good program to have done as part of your work history?
<p>I am wondering what is a valuable program (or programs) that a prospective employer hiring in Java, Python, C# or any high level programming language would like to see in the candidates work history?  This or these programs would be seen as valuable indicators for the persons knowledge of the language.</p>

<p>A list of useful apps would be helpful.  Just let me know what you think is a good app to have on your resume or CV.</p>

<p>Thanks everyone for your comments and suggestions.</p>
