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.

Speaking of security

Ken Chiacchia Monday April 08, 2013
Voiceprint authentication a la "Star Trek" could be poised to become reality Now, what was that password? This was the system that needed eight digits, right? Did it require symbols, or just letters and numbers?  Today's password-driven electronic security systems have a face only a system security administrator could love. Better to use some kind of biometric--something physically a part of us, marking us as ourselves. Some systems already use fingerprints.  

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. 

Screenshot: Smart cookie

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."
