Comment: Fuel efficiency is the wrong metric (Score 1) 1114

by information_retrieva (#25356133) Attached to: Fuel Efficiency and Slow Driving?
Most of the hypermiling I've read about is about increasing mileage, not about using less fuel. Some of the techniques involve driving out of your way if you know you can get above average mileage for doing so. To me, this is silly.

If you want to save money on fuel, use less fuel.

For example, because a warm engine is way more efficient than a cold engine, trip combining can be a big fuel saver. Similarly, with only a little planning, preparing dinner at home saves fuel.

Perhaps we should call this Agile Driving? ... eXtreme Driving? ...Lean Driving?

+ - The Real Function of the Appendix->

eldavojohn writes "PhysOrg has an interesting article on research currently up for review concerning the appendix. Long considered an evolutionary oddity in the human body or at most a nuisance that needs to be removed, it now seems that the medical community is hypothesizing that in the past it acted as a "safe house" for the good germs that populate our digestive tracts. In the past, this would have been necessary had something destroyed the germs in someone's digestive system although today you can reclaim these germs just by interacting with other people. The article also notes that appendicitis occurs at a lower rate in underdeveloped countries and adds to the theory that appendicitis may be another case of an overly hygienic society triggering an overreaction by the body's immune system. It's long been theorized that asthma, allergies & polio are diseases or conditions that increase when we are not exposed to the pathogens at a young age. Could appendicitis be another case where our increasing sanitation reduces our exposure to things that kill our digestive germs thus, in turn, causing us to over react when we finally are exposed to them? This research certainly raises some interesting questions."

+ - Why HP Still Believes In Unix?

Submitted by techner
techner (1157255) writes "A decade ago, Intel was shipping the Pentium II processor and Linux was a fringe operating system used by a few Internet fanatics. No one at the time would ever have thought the two in combination would be a match for Sun's SPARC/Solaris combination, HP's PA-RISC/HP-UX, IBM's POWER/AIX or SGI's MIPS/IRIX. Funny what a decade can do. Even though there has been a big shift in the marketplace, high-end Unix has not curled up and died in spite of the advent of Windows and Linux Server. IDC puts the market at around $19 billion annually with single-digit annual growth, and the market is split almost evenly between Sun, HP and IBM. a Question is raising "Why HP Still Believes In Unix?""

bednarz writes "Scientists at Carnegie Mellon University have developed an online game designed to teach Internet users about the dangers of phishing. Featuring a cartoon fish named Phil, the game, called Anti-Phishing Phil, has been tested in CMU's Privacy and Security Laboratory. Officials with the lab say users who spent 15 minutes playing the interactive, online game were better able to discern fraudulent Web sites than those who simply read tutorials about the threat. Network World has the story: http://www.networkworld.com/news/2007/092507-phish-carnegie-mellon.html"
