When I remote desktop to Windows machines most of the time the fonts just looks ugly. This can be improved by enabling ClearType and I do this every time I connect to a box which I do several times a day. Below is a Python code that enables ClearType which I shamelessly copied from StackOverflow. Reference(s): http://stackoverflow.com/questions/5676768/enable-disable-cleartype-in-windows7

I have been poking around STAX/STAF recently and I found a need to generate UUID or GUID in Windows. I tried uuid module in CPython but I can't call it inside my STAX job. I tried to create STAX process but I noticed that if the program is under heavy usage I cannot guarantee that the STAX process that runs the CPython gets the resulting UUID string. Since STAX is using Jython, I reasoned out that this should be possible in Java. A quick search in Google shows java.util.UUID. This class is just what I need. So, basically, in Jython I can generate a UUID using the following command: import java print java . util . UUID . randomUUID () ~ts~
