Yesterday was the first walk through for my CodeMash presentation on enterprise development with Python. Overall it went rather well. I had a little touble with my slides, but I was able to wing it for the missing and outdated slides. Before work I exported the Open Office presentation as a Power Point and emailed it to myself. At work an hour before the scheduled time I tried to opened the attachment. Unfortuately the file was corrupt. After some frantic searching I found an older version on my work laptop. The version I found was very much out of date. The slides were out of order and lacking some details. This forced me to do some of the presentation from memory. I at least proved to myself that I was able to remember the material, even in front of a crowd.
