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.

Putting Watson to work

Linda K. Schmitmeyer Friday January 09, 2015
Technical competitions can spur world-changing innovations. Frenchman Nicolas Appert was awarded 12,000 francs for developing an airtight food-preservation process that allowed Napoleon to feed his far-flung troops, and canned food was born. Charles Lindbergh received a $25,000 cash prize for his solo flight across the Atlantic, beating his competitors (six of whom died trying) and long-distance air travel soon became routine.

Ready for blast-off

Meghan Holohan Friday January 09, 2015
On a clear February day in the Mojave Desert, a Masten Xombie rocket launched. It landed again on the same pad, 78 seconds later. That might not sound like much, but the little more-than-a-minute flight provided Astrobotic with valuable information that the team will use to win the Google Lunar X Prize.

In 1986, the most impressive computer on the market was Compaq’s 44-pound Deskpro 386, with its 32-bit microprocessor and four kilobytes of memory. 

WPI-CMU robotics team is hot on CHIMP’s heels

Jason Togyer Wednesday June 18, 2014
On the heels of Tartan Rescue’s CHIMP in the DARPA Robotics Challenge trials was another robot with CMU involvement—WARNER, a humanoid robot entered by Worcester Polytechnic Institute. Four members of the WARNER team are from CMU’s Robotics Institute, including Chris Atkeson, a professor of robotics and human-computer interaction.
