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.

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." 

Sweating the details

SCS startup Safaba develops smarter translations for specialized clientsSay a marketing executive at a large company needs to translate new product information on her company website from English to French within a few hours. She's not fluent enough in French to do it herself, so she has several options--she can hire a human translator or a translation agency. She can also use a readily available online translation program, such as those offered by Google and Microsoft's Bing. 

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?
