My latest screencast is a lecture from G14FUN Functional Analysis where I prove the Baire Category Theorem for complete metric spaces: a countable intersection of dense, open subsets of a complete metric space must be dense.
The screencast is available from
This screencast includes a picture-in-picture (PIP) of me in the bottom right hand corner along with the audio and the screen-capture movie from my tablet laptop. I am quite pleased with the way the PIP has come out this time. The webcam recorded this footage at 320×240 resolution, and I scaled it down slightly for the final production in Camtasia.
The audio quality is also improved from some recent screencasts: for some reason I had the microphone sensitivity setting in Camtasia set too high, and this was producing hiss and distortion.
