I have created number of googlecode projects in attempt to try out new codes and ideas in the past. I now have links to all of them in my consolidated playground area http://code.google.com/p/zemiandeng/

There is also the "java-tool" with misc command line programs that I have collected over the years.
I also have stored a more reasonable preferences with Eclipse workspace, and few more custom Cygwin/Bash scripts setup.
