01:43 PM - Back to the grindstone Got back into the swing of things today, homing in on taskings at work and tasking myself with work at home. Figured out how to record streaming lectures onto VHS today, which should make it much easier to excercise my body and mind at the same time. I have trouble sitting still through a lecture and I get downright bored during a typical aerobic workout, and hopefully this will solve both problems. Waxing philosophical for a moment, the data stream itself is a pretty amazing thing. A typical lecture is filmed on an ordinary camera and transferred to digital form by some means or another (e.g. DVD burner) and then reencoded into a streaming Real Media file. This file is then streamed via a secure server to my house, where it is converted back into analog form in order to travel over an ordinary cable connection. Once it gets into my house, it is demodulated back into its digital form and played back as audio/video on my laptop. Oftentimes, the laptop is connected to a VGA -> TV converter which once again turns the film into an analog signal in order to allow me to view it on my television and tape it on my VCR. I suppose in the not-too-distant future we will go all digital, but in the meantime, to process is something like "ADDADA" which is quite a few steps in order to enjoy a lecture on tort law. (
The truth is that capitalism has not only multiplied population figures, but at the same time, improved the people's standard of living in an unprecedented way. Neither economic thinking nor historical experience suggest that any other social system could be as beneficial to the masses as capitalism. by free online poker Live Webcam Girls...We're college room mates just trying to have some fun! |
