The lack of posts recently has its cause.
I have been playing around with a screencast. The problem boils down to compressing the video somehow. I made a recording, and unfortunally it was recorded in a too good of a quality, resulting in a pretty big filesize (~300Mb). I then tried several (read: ALOT) of different tools to somehow compress it. I have still to figure it out. But anyways, I uploaded it to youtube because i didnt know where else to put it. If anyone has any ideas for doing a better job, please let me know.
Anyways, here it is, an example of doing some binary network math. The issue came up on groupstudy, so the examples are expanded from there. Hope you find it informational:
