Google Pulls Plug On Programming For the Masses 236

theodp writes "Google has decided to pull the plug on Android App Inventor, which was once touted as a game-changer for introductory computer science. In an odd post, Google encourages folks to 'Get Started!' with the very product it's announcing will be discontinued as a Google product. The move leaves CS Prof David Wolber baffled. ' In the case of App Inventor,' writes Wolber, 'the decision affects more than just your typical early adopter techie. It hurts kids and schools, and outfits like Iridescent, who use App Inventor in their Technovation after-school programs for high school girls, and Youth Radio's Mobile Action Lab, which teaches app building to kids in Oakland California. You've hurt professors and K-12 educators who have developed new courses and curricula with App Inventor at the core. You've hurt universities who have redesigned their programs.' Wolber adds: 'Even looking at it from Google's perspective, I find the decision puzzling. App Inventor was a public relations dream. Democratizing app building, empowering kids, women, and underrepresented groups — this is good press for a company continually in the news for anti-trust and other far less appealing issues. And the cost-benefit of the cut was negligible-believe it or not, App Inventor was a small team of just 5+ employees! The Math doesn't make sense.'"

This is the advice you want to follow. Use XFOIL or some other panel method based program to analyze airfoils along side of your wind tunnel stuff.

You can talk about all the things it doesn't do well (boundary layer separation, transonic flow...) and show them some Color Fancy Drawings made by a more advanced simulation as an aside.

The Environmental Impact of PHP Compared To C++ On Facebook 752

Kensai7 writes "Recently, Facebook provided us with some information on their server park. They use about 30,000 servers, and not surprisingly, most of them are running PHP code to generate pages full of social info for their users. As they only say that 'the bulk' is running PHP, let's assume this to be 25,000 of the 30,000. If C++ would have been used instead of PHP, then 22,500 servers could be powered down (assuming a conservative ratio of 10 for the efficiency of C++ versus PHP code), or a reduction of 49,000 tons of CO2 per year. Of course, it is a bit unfair to isolate Facebook here. Their servers are only a tiny fraction of computers deployed world-wide that are interpreting PHP code."
