In a drought, over-irrigated lawns lose 70 billion gallons of water a year

News From NSF - Wed, 05/24/2017 - 10:00

In the summer of 2010, Los Angeles lost about 100 gallons of water per person per day to the atmosphere through evaporation, mostly from overwatering of lawns and trees.

Lawns accounted for 70 percent of the water loss, while trees accounted for 30 percent, according to a study published today in the journal Water Resources Research. The research was funded by the National Science Foundation (NSF) and conducted by Diane Pataki and Elizaveta Litvak of the University of ...

How do we create cyberattack defenders?

ComputingEd - Wed, 05/24/2017 - 07:00

 

Roger Schank (famous AI and cognitive science researcher, the guy who coined the term “learning sciences”) is putting his expertise to the task of creating cyberattack defenders.  The description of his process (linked below) is interesting.  It has all the hallmarks of his work — innovative, informed by research, driven by concrete tasks.  Notice the strong claim that I quoted below.  We shouldn’t be aiming for general cyber attack defense skills.  These skills are going to be industry-by-industry specific.  He’s directly informed by the research that suggests that these skills are unlikely to generalize.

One of the big questions is: where are we going to get the students?  How do we recruit students into this kind of program?

How can we help? The cyber attack course Socratic Arts is building for the DOD will be modified to make the projects specific to particular industries. The banks’ problems are obvious: hackers might want to steal money. Pharma’s problems are obvious: hackers might want to steal secrets. We intend to put out versions of our cyber attack course for each industry. These courses will take 6 months for a student to complete. We are not interested in giving an overview in the typical one week course that is no more than an intro. We want to train real cyber attackers who can help. The only way to learn is by practice (with advice). That’s how you learn to ride a bike and that’s how you learn to do anything.
