Comment Calculus is helpful in software development (Score 1) 365

I (with another engineer) recently designed a pump that needs to move a fluid in both directions. When starting, stopping, or reversing directions, the pump accelerates and decelerates along a programmable curve. The amount of fluid moved is the area under the velocity curve. It needs to be measured. To compute it, I take a definite integral. There, I've used calculus as a SW engineer. This was not the first time.

Comment What about datetime libraries? (Score 1) 307

Code libraries that deal effectively with dates, times, and calendars has sophisticated support for daylight savings time: that they know when different regions change their clocks, how to convert between DST and non-DST time zones, etc. Will all that code break if it thinks the clocks are switching twice a year, but they aren't doing so any longer?

Satellites Spy On Black Friday Shoppers 171

MojoKid writes "Those satellites in space don't just take spy pictures. On this Black Friday 2010, they actually took pictures of you, and your rush to Black Friday shopping deals. The research is being done to see what consumer demand this year means for retail stocks. The trend, so far, has been favorable. The companies involved in this are Remote Sensing Metrics and Digital Globe. Remote Sensing Metrics is a Chicago-based consulting firm that analyzes the satellite imagery. In turn, it purchases those images from Colorado-based company Digital Globe, which operates its own satellites."

Is Google Polluting the Internet? 378

Pickens writes "In 1998, Larry Page and Sergey Brin made a promise: 'We believe the issue of advertising causes enough mixed incentives that it is crucial to have a competitive search engine that is transparent and in the academic realm.' Now, Micah White writes in the Guardian that the vast library that is the internet is flooded with so many advertisements that this commercial barrage is having a cultural impact, where users can no longer tell the difference between content and advertising, and the omnipresence of internet advertising constrains the horizon of our thought. And at the center of it all, with ad space on 85% of all internet sites, is Google. In the gleeful words of CEO Eric Schmidt, 'We are an advertising company.' The danger of allowing an advertising company to control the index of human knowledge is too obvious to ignore, writes White. 'The universal index is the shared heritage of humanity. It ought to be owned by us all. No corporation or nation has the right to privatize the index, commercialize the index, censor what they do not like or auction search ranking to the highest bidder.' Google currently makes nearly all its money from practices its founders once rightly abhorred. 'Now it is up to us to realize the dream of a non-commercial paradigm for organizing the internet. ... We have public libraries. We need a public search engine.'"
