Next Steps for XRDS
Organic Growth

We received a lot of emails, tweets, andpostsabout the launch issue of XRDS, the first rebranded edition of this magazine with its new look and new editorial focus. It’s been overwhelming and encouraging (see “Inbox,” page 5

for some of the feedback). Thank you for the kind words and comments!

We’re already using what you liked and didn’t like to reshape XRDS. You’ll start to see changes incorporated into this issue and future ones. Like the volunteer team that runs it, XRDS is organic.

We’re learning and evolving. So keep reading and sending us comments; it’s greatly appreciated.

Having now served as editor-in-chief for a year, I can say that running (and reinventing) a magazine is remarkably similar to debugging a large program. Adding to that complexity is the fact that it’s a highly parallel process—a topic you’ll read about in this issue. There are processes that deadlock on each other, periods of resource contention where the team is thrashing, and editors who “malloc” a lot of my memory and never free it. Sometimes, when we fix a “bug,” new ones appear. It’s a highly iterative process, and I’m glad we’ve got a staff of CS-minded people to help work through the challenges.

Overall, I hope you’ll agree that each subsequent release of XRDS gets a little better. And we’ve still got some exciting things in the pipeline.

Hitting Our Stride

Having wrapped up our second XRDS issue (the one that’s in your hands or on your screen right now), we’re finally hitting our stride. So what’s next?

For the Winter 2010 release, we have a whopper issue coming together on human computation with an all-star author line up. For Spring 2011, we’re assembling a fascinating group of articles on how technology and computing are transforming banking, currency, and commerce. Farthest out, in Summer 2011, we’ll be turning out attention to green technologies, exploring how computer science plays an important role in sustainable efforts, like smart electrical grids.

If we’ve touched on an area of interest to you, please consider writing an article, opinion piece, or even sending us a related photo or image for publication. Submissions are welcomed from students, faculty, and industry (see http://xrds.acm.org/authorguidelines. cfm for more tips on how and what to submit). If you have something particular in mind, we suggest pitching it directly to us first to open a dialogue about the subject: [e-mail]. Then we can work with you to make sure it’s a good fit—for you, for us, and for the rest of the student community.

He completed his BA and MS in computer science at New York University in 2005 and is a recipient of a Microsoft Research Ph D Fellowship. Before coming to CMU, he worked at IBM Research and AT&T Labs. He has since worked at Microsoft Research and Disney Imagineering. Currently, he is investigating how to make small devices “big” through novel sensing technologies and interaction techniques.
