The internal organization and operation of digital computers. Machine architecture, support for high-level languages (logic, arithmetic, instruction sequencing) and operating systems (I/O, interrupts, memory management, process switching). Elements of computer logic design. Tradeoffs involved in fundamental architectural design decisions.
Capitalism: Success, Crisis and Reform (PLSC 270) Professor Rae uses the case of Polaroid cameras to highlight key features of the capitalist system. Polaroid's business model, corporate culture, and firm trajectory are discussed. Important firm decisions are analyzed, including product offerings and mergers. Professor Rae explores factors that led to Polaroid's demise, including the company's relentless focus on scientific innovation at ...more
Trip Hawkins, chairman and CEO of Digital Chocolate, believes that persistence is a very important quality in entrepreneurs. It helps to overcome road-blocks and stick to one's beliefs no matter what others say, he adds. He talks about the notion of the big idea - doing something different than what everybody else is doing or something that nobody has thought of.
In this lecture Professor Hungerford discusses how the novels we read are shaped by legal and market constraints. She traces a history of censorship from the Comstock laws, to the policing of Joyce's Ulysses and Ginsberg's Howl, and shows how changes in publishing practices have tended to penalize more unusual, less profitable books. Hungerford also touches on the canon debates of the 80s and 90s (citing John Guillory and Toni Morrison), a...more
This course serves as an introduction to the theory and practice behind many of today's communications systems. 6.450 forms the first of a two-course sequence on digital communication. The second class, 6.451, is offered in the spring. Topics covered include: digital communications at the block diagram level, data compression, Lempel-Ziv algorithm, scalar and vector quantization, sampling and aliasing, the Nyquist criterion, PAM and QAM m...more
This course is the second of a two-term sequence. The focus is on coding techniques for approaching the Shannon limit of additive white Gaussian noise (AWGN) channels, their performance analysis, and design principles. After a review of Principles of Digital Communication I and the Shannon limit for AWGN channels, the course begins by discussing small signal constellations, performance analysis and coding gain, and hard-decision and soft-d...more
Why print photos when the blog is king? And who prints photos in the age of digital cameras? Shutterfly CEO Jeff Housenbold explains how an old-fashioned business like photo printing is surviving - and thriving - in electronic media. He also discusses how technological innovations are reducing environmental resources in the photo industry landscape.

May 30, 2008 lecture by Hiroshi Ishii for the Stanford University Human Computer Interaction Seminar (CS547). Tangible Bits seeks to realize seamless interfaces between humans, digital information, and the physical environment by giving physical form to digital information, making bits directly manipulable and perceptible. Their goal is to invent new design media for artistic expression as well as for scientific analysis, taking advantage...more
Wirt talks about how the convergence of technology is an interesting trend that has led to an influx of multi-functioning devices. Convergence devices save space, add convenience, and can sometimes enhance the functionality of the combined product. The Palm Treo is a great example of a convergence device and functions as a phone, handheld organizer, wireless email, text messaging, web browsing and even a digital camera.
