Comment This is no Space Shuttle, its better. (Score 5, Informative) 111

Space Shuttle:
Payload to GTO: ~3000 kg.
Average cost per flight: 1.5 billion (cost of shuttle program / number of launches)


Falcon 9 rocket:
Payload to GTO:~2000 kg
Average cost per flight: 50m (cost of expendable rocket)


Falcon 9 rocket with grasshopper gear:
Payload to GTO:~1000 kg (rough estimate)
Average cost per flight: ~200,000 (expected figure for fuel + incidentals)


You can do the math to figure out why this is a big deal.

Users Abandon Ship If Online Video Quality Is Not Up To Snuff, Says Study 155

An anonymous reader writes "The first large scientific study of how people respond to poor video quality on the Internet paints a picture of ever rising user expectations and the willingness to abandon ship if those expectations are not met (PDF). Some nuggets: 1) Some users are willing to wait for no more than 2 seconds for a video to start playing, with each additional second adding 6% to the abandonment rate. 2) Users with good broadband connectivity expect faster video load times and are even more impatient than ones on mobile devices. 3) Users who experience video freezing watch fewer minutes of the video than someone who does not experience freezing. If a video freezes for 1% of its total play time, 5% less of its total play time is watched, on average. 4) Users who experience failures when they try to play videos are less likely to return to the same website in the future. Big data was analyzed (260+ million minutes of video) and some cool new data analysis techniques used."

I think that every engineer on planet earth should have -A mechanical pencil -A Protractor -An engineer's scale ( those three sided rulers) -Calipers - TI83/84 I'm not one of those old school flannel wearing engineers, I do most everything on a computer, but there is a lot of value in having a traditional drafting desk with tools like this, regardless of what type of engineering you do.
