351 Topic Videos

The videos below are from an old online version of 351 and are available thanks to Luis Ceze and Gaetano Borriello (and previous 351 TAs Katelin Bailey and Rachel Sobel). Viewing these videos is generally optional, though they may be useful for reviewing lecture content or use of important tools for lab. We may occasionally assign some videos to supplement topics which we may cover only briefly in lecture.
