All page and section numbers for the readings refer to the third edition of the Computer Systems: A Programmer's Perspective book. There are significant changes from the second to third edition.
Slides will usually be available in PDF and PPT format, PDFs before each lecture and with ink/markup from lecture posted afterwards. Powerpoint sadly does not allow fonts to be embedded, so if you are viewing the powerpoint files, you may wish to download and install a couple free fonts which I use: Anonymous Pro and Roboto. The process is quite straightforward, and should ensure that all the text is in the right place.
