Ubuntu: New software packages installed

As a follow up to my previous post, I just installed GNU Linear Programming Kit (GLPK) and PyMathProg. GLPK is recommended by Larry of http://industrialengineertools.blogspot.com/ and PyMathProg is a Python implementation of GLPK. I also installed SimPy which is a Python queuing simulation modeler. At some point, after I build a core set of skills, I will provide samples of theses programs in the blog.
