The Link is the magazine of Carnegie Mellon University’s School of Computer Science.

Its name recognizes the pioneering work of two of the School of Computer Science's co-founders, Allen Newell and Herb Simon, who invented the use of linked-list data structures for representing complex information.

But it also serves as the link between the School of Computer Science and more than 10,000 alumni, colleagues, parents and other friends around the world.

Decoding a cyber-fingerprint

Mary Lynn Mack Monday April 08, 2013
Your typing rhythm holds clues to your identity, and maybe even your future health The blink of an eye takes 300 to 400 milliseconds. It takes less time than that--about 90 milliseconds, on average--to press a computer key while typing. Individual keystrokes as well as the "rhythm" of typing a word, sentence or document are forming the basis of a cyber equivalent to handwriting or fingerprint analysis.  

Is the end near?

Daniel H. Wilson's Robopocalypse plots a robot uprising in the near future, but (so far) the science is still fiction 

In the Loop: John Reynolds

Jason Togyer Monday February 04, 2013
John C. Reynolds has been a professor of computer science at Carnegie Mellon University since 1986. He retired from active teaching Jan. 1. A graduate of Purdue University, Reynolds earned his Ph.D. in theoretical physics from Harvard University. His main research interests have been the design and definition of programming languages and the specification of program behavior. 

Research notebook: <br>How design practices affect results

By Steven P. DowIn their 2001 book Art & Fear: Observations On the Perils (and Rewards) of Artmaking, David Bayles and Ted Orland share a story about a ceramics teacher who divided his class into two groups. He told one half they would be graded on quantity, so they should "produce as many ceramics you can in one quarter, that will be your grade," while he told the other half they would be graded based on one good ceramic. 

Letters to Randy Pausch

Jason Togyer Thursday November 29, 2012
Five years ago, as Randy Pausch's "last lecture" spread around the world via email, social media and news broadcasts, tributes poured into his office at CMU. By early 2008, Pausch, a professor of computer science, human-computer interaction and design, reported receiving more than 6,000 emails from people who said his lecture had (in his words) inspired them to "stop feeling sorry for themselves." 

Then and now

That's Ivan Sutherland holding the great-granddaddy of today's Mobots. Long before his pioneering work in computer graphics, Sutherland (E'59, H'03) was interested in robots that could navigate mazes and react to stimuli much as an animal would.
