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.

All in good time

Linda K. Schmitmeyer Monday April 08, 2013
Traffic-sensitive signals developed at the Robotics Institute are saving fuel, time and drivers' nerves Gregory Barlow knows a lot about traffic, and not just how long it takes to commute from his home in Squirrel Hill to his office in Newell-Simon Hall, where he works with CMU research professor Stephen Smith on tackling traffic congestion in urban areas. 

Giving Back: Pradeep Sindhu

Mark W. Dorgan Monday April 08, 2013
As founder, vice chairman and chief technology officer of Juniper Networks, Pradeep Sindhu has his eyes on sustainable business models and the bottom line. But Sindhu (CS'83,'84) remains a computer scientist at heart, with an interest both in the design of complex systems and in the work of the School of Computer Science. Recipient of an alumni achievement award in 2008, Sindhu says he values the connections he maintains with SCS. 

Then and Now: Computer science's female pioneers

Jason Togyer Monday April 08, 2013
Do you think women were always a minority in computer science? Think again. You may already know about computing pioneers such as Grace Hopper and Ada Lovelace, but in the early days, women were highly visible at every level of computer programming--including entry-level coders. 

Dean's Message

Jason Togyer Monday April 08, 2013
Reflecting on the Cohon EraJared Cohon will be stepping down as president of Carnegie Mellon on June 30 after 16 years of service.It's remarkable how the School of Computer Science has flourished during that time period. Our total student enrollment, including undergraduate, masters and Ph.D.'s, has almost doubled to its current level of 1,600. Our research budget has nearly tripled, to its current level of $110 million.

It takes a tough robot to disassemble a fragile cookie.By now, you've probably seen the video, which has been viewed more than a quarter-of-a-million times on YouTube. The makers of Oreo cookies recruited HERB, the Home Exploring Robot Butler developed at Pittsburgh's Quality of Life Technology Center, as part of a national advertising campaign called "Cookie Vs. Creme." 

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.
