This is a very good introduction to using wxPython to create GUI applications in Python. Currently I've read about 70% of the book and found it quite easy to follow, the examples are quite concise, but still illustrate some powerful concepts (especially the grid table in Chapter 5 and the simple drawing application in chapter 6). Source code to the examples is available from the publisher's web site, but sometimes one learns more from actually typing in some of these that just downloading and running them. That's one of the beauties of Python, you can actually type in some stuff in the Python shell window and interactively experiment with things.
Incorporating HTML into wxPython. Using PIL (Python Imaging Library) within a wxPython application.
intersection = filter(lambda x:x in list1, list2)
union = list1 + filter(lambda x:x not in list1, list2)
difference = filter(lambda x:x in list2, list1)
distinct = filter(lambda x:x in not list2, list1) + filter(lambda x:x in not list1, list2)
To make this strange material, scientists start with a liquid alcohol like ethanol and mix it with silicon dioxide to form a gel. Then, through a process called supercritical drying, the alcohol is forced out of the gel, typically with high-pressure carbon dioxide. With this drying process, the gel does not collapse or lose its volume. It appears holographic because the silicon dioxide scatters shorter wavelengths of light much like air in the daytime sky.This stuff insulates so well you probably would have to cool you house in winter if you could afford it. So my question is, if the raw materials for making this stuff are so cheap and abundant, and its been known about for over 70 years, why is this not commercially available?

The material was not new. In 1931, Steven S. Kistler was a pioneer in making the substance at the College of the Pacific in Stockton, Calif., now the University of the Pacific. But, Dr. Tsou said, the material was not used much, except in powdered form as a nontoxic anti-caking agent for food.
