Listen and Record

Purpose: To learn about the social impact of Computer Science on the world. Assignment: You will listen first and record the secret passcode for verification. You will type the secret passcode when you drop off your recordings. After you listen to each audio file I have, you will then record it and drop it off into google classroom. Make sure you save the file as an mp3. Resources: Audacity. Check to see if you have already installed audacity. Go to the search bar and type audacity.

(Start here) Connecting the Dots The way we leave fingerprints and footprints is only part of what is new. We have always left a trail of information behind us, in our tax records, hotel reservations, and long distance telephone bills. True, the footprints are far clearer and more complete today than ever before. But something else has changed—the harnessing of computing power to correlate data, to connect the dots, to put pieces together, and to create cohesive, detailed pictures from what would otherwise have been meaningless fragments. The digital explosion does not just blow things apart. Like the explosion at the core of an atomic bomb, it blows things together as well. Gather up the details, connect the dots, assemble the parts of the puzzle, and a clear picture will emerge. ..... We give away information about ourselves—voluntarily leave visible footprints of our daily lives—because we judge, perhaps without thinking about it very much, that the benefits outweigh the costs. To be sure, the benefits are many. (stop here)
