Strong Storms Over Oklahoma
NASA – This image of the storm system that generated the F-4 tornado in Moore, Oklahoma was taken by NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard one of the Earth Observing System (EOS) satellites. The image was captured on May 20, 2013, at 19:40 UTC (2:40 p.m. CDT) as the tornado began its deadly swath.

By Colin Walls – How do you acquire the specialist skills needed to develop software for embedded systems?
Learning at college may be difficult, so many engineers pick up the skills on the job, starting with an electronics or computer science background. An intelligent engineer can learn a lot from more experienced colleagues. Indeed this is largely how my own career started and I have mentored quite a few younger guys who had come out of college with few clues. more> http://tinyurl.com/amyc6ft

Supersonic Noise
NASA – The Twin Rectangular Jet model, installed on the Nozzle Acoustic Test Rig in the Aeroacoustic Propulsion Laboratory at NASA’s Glenn Research Center, is being tested to determine the acoustic impact of engine configurations on low sonic boom aircraft for the High Speed Project of the Fundamental Aeronautics Program.
The High Speed Project is a multi-center effort to develop and test the technologies of a new generation of aircraft that can fly at supersonic speeds. Glenn’s research involves predicting the airport noise of these novel aircraft by examining innovative airframes and propulsion integration that are different from the conventional tube-and-wing aircraft observed at commercial airports.
Inside the aeroacoustic dome, this generic, low-fidelity aircraft engine exhaust model features twin rectangular nozzles. Researchers are investigating the impact of having the propulsive exhaust come from the slot nozzles atop the aircraft. Testing the proposed components of these high- speed aircraft will help manufacturers meet the noise standards required around the nation’s airports.

By Sam Gustin – Tumblr has long been considered a major prize, so it’s no surprise that Yahoo! isn’t the only one interested in the company. Tumblr has also reportedly held talks with both Facebook and Microsoft, according to Forbes. Of course, Tumblr CEO David Karp may decide to hold out — he’s reportedly raising a new venture capital round that values the company at $1 billion. Or he may opt for a “strategic investment,” in which Yahoo! or some other big company invests in Tumblr, which would then remain independent. Tumblr has already raised $125 million at an $800 million valuation. more> http://tinyurl.com/cmjo8aw
