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.

Robots for Life

Jason Togyer Sunday May 02, 2010
Pittsburgh's Quality of Life Technology Center is solving the human-machine equation and spawning a new industry in the process.By Tom Imerito"Quality of life." It's one of those stubbornly vague terms that are hard to define. For some people, having a good "quality of life" might mean getting a job that allows them to spend lots of time with family. For others, good "quality of life" might mean a certain possession, like a luxurious home. 

Technology for a Greener Earth

Computer science and robotics researchers are searching for practical ways to reduce carbon emissions and energy useBy Jason TogyerIn a four-by-six-mile rectangle of a dusty mountain range about one hour east of Palo Alto, Calif., sits the Altamont Pass Wind Farm, a collection of nearly 5,000 power-generating electric wind turbines.  

Algorithms as Art

Jason Togyer Friday April 30, 2010
Alumnus and faculty installations in the Gates and Hillman Centers draw inspiration from technologyBy Meghan Holohan"Do you want me to stand in the art?" asks Scott Draves (CS'97). He positions himself in front of a large screen in a tiny, dark room at the Michael Berger Gallery on Pittsburgh's South Side. Blobs that resemble miniscule jellyfish pulsate and swirl across his face, highlighting his white shirt. Reds, yellows, greens and blues dance across the screen, tattooing Draves' skin and clothes.

The Rise of the Expert Amateur: Citizen Science and Neo-VolunteerismBy Eric PaulosIf you cannot measure it, you cannot improve it. -- Lord KelvinIn the Living Environments Lab, we conduct research focused on societal problems. More specifically, we focus on the critical intersection of human life, our living planet and technology. 

Then and Now: Web Extra

Jason Togyer Wednesday April 28, 2010
Though he wasn't a member of the computer science faculty, Carnegie Mellon Professor Clarence Zener had a profound effect on the design of digital computers and the algorithms they employ.In 1934, while at Princeton, Zener discovered that certain electrical insulating materials--semiconductors--were able to regulate and limit voltage. That led to the invention 20 years later of Zener diodes, tiny solid-state voltage regulators that made reliable desktop computers a reality.
