U.S. Women in Computing: Why Isn’t It Getting Better?

We've known for over a decade that there are too few women in computing in the U.S., but recent reports point out that it's not getting better: Not in any academic degree, not in IT company management.

Possible Hadoop Trajectories

Hadoop has spread rapidly in the last few years as a platform for parallel computation in Java, but we believe a lot of improvement will be required for serious production use in the science domain of a large national laboratory.

No, Maybe, Yes, Obviously: Telling the Future the Past

The Kubler-Ross model of the stages of grief — denial, anger, bargaining, depression and acceptance — is sometimes an apt description of the culture change required when technology transitions occur. High-performance computing has experienced this many times.

Turing’s Sunflowers

It's the Turing Centenary Year. Why not plant a sunflower to celebrate? Manchester University, Manchester Science Festival and the Museum of Science and Industry are asking people to grow sunflowers and count the number of spirals in their seed heads in order to test Turing's theory that the seeds grow in Fibonacci sequences.

Avoiding the Rabbit Hole of Bad Science

The scandal surrounding the recently published so-called empirical evidence for precognition has caused psychologists to reconsider the way they analyze their data, and highlights the importance of replication. What can empirical subfields of computer science learn from this?

Why Don’t We Use Worksheets in Computer Science Education?

Worksheets (short, constrained, sets of exercises with mostly fill-in-the-blank, true/false, and multiple choice activities) are unusual in CS education. Use of worksheets is a natural progression towards a broader audience for CS education.

All Grown Up Now: Service and Serial Reciprocity

Computing is central to the debate about so many aspects of our present and future that we have a duty and responsibility to be active and enthusiastic participants. By paying it forward (serial reciprocity), we create an environment where a new generation can thrive, just as the founders of the field did for us.
