A couple of days ago, my parents bought their first HDTV. Since it has a USB port that can be used to show pictures stored on a flash drive, I found myself in the position of finally using an old 512 MB stick I had lying around.

The solution, it turns out, is relatively simple. Follow along. Continue reading “Installing the MySQLdb Python module on Snow Leopard” →
