merbs writes: The U.S. Department of Energy anticipates that the amount of electricity generated by wind power to more than double over the next five years. Right now, wind provides the nation with about 4.5 percent of its power. But an in-depth DOE report (PDF) released yesterday forecasts that number will rise to 10 percent by 2020—then 20 percent by 2030, and 35 percent by 2050.

Hint: how prevalent are handguns in Germany?

It would depend on the lander or even the landkreis... it's roughly 30 guns per 100 persons averaged over Germany, in my landkreis it's just below 90 handguns per 100 persons (5 years old statistic). That's just privately owned handguns... if you throw in the hunting weapons and service weapons, there's probably more weapons than people.

In the real world, I have never been able to get even close to the announced mpg-rating of the 2011 econetic fiesta. I had one for 3 months as a replacement vehicle and I enjoyed it except for the mileage. My 2011 A3 2.0TDI has consistently given me a better mileage, even with the DSG gearbox... I do get around 54 MPG with the Audi.

8. Oracle managed services failed to grasp what a replication timestamp was. For a week, their daily report was indicating that the replication had worked flawlessly even tho the timestamp on the target hadn't changed.

9. Oracle managed services sent me the daily report of another company, with financial information, on more than one occasion. They have also obviously sent my customer's data to other companies.

10. Back when Sun was still a separate entity, they won a 4 years staffing/project contract where the first action point was implementing unified authentication with LDAP (the site was mostly Solaris 8, with some HP-UX and a pair of AIX boxen). They only successfully delivered this feature 7 years later, after three contract extensions, when the whole site had been migrated to Solaris 10. They were surprised when they didn't win the new staffing/project contract and even more surprised when the customer massively migrated to RHEL.

retroworks writes "Just over a year ago, complex systems theorists at the New England Complex Systems Institute warned that if food prices continued to climb, so too would the likelihood that there would be riots across the globe. Sure enough, we're seeing them now. The paper's author, Yaneer Bar-Yam, charted the rise in the FAO food price index—a measure the UN uses to map the cost of food over time—and found that whenever it rose above 210, riots broke out worldwide. It happened in 2008 after the economic collapse, and again in 2011, when a Tunisian street vendor who could no longer feed his family set himself on fire in protest."

What Would You Do With the World's Most Powerful Laser? 143

sciencehabit writes "This week, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California announced an important milestone on the road to achieving ignition, which could lead to producing controlled fusion reactions here on Earth. But NIF isn't just about harnessing the energy of the stars—it's about learning how stars produce their energy in the first place. In fact, pushing matter to extreme pressures and temperatures lets scientists explore all sorts of unanswered questions. At the annual meeting of AAAS in Chicago four physicists sat down with Science Magazine to discuss NIF's basic science potential and what experiments they would do if they had the laser all to themselves."

I never said it was an honest measure, but it is the measure used by the hard drive industry. It is also very similar to quality measures in many other industries. You take a reasonable sample, run a test for a certain amount of time and infer/extrapolate reliability figures based on the test. On the back-end, you redesign your process to eliminate as many variations as possible on the manufacturing side.

The alternative would be to really test the disks for 3-5 years in a lab before releasing them on the market, or really testing a large amount of drive trains for 10 years and so many miles before releasing to market. The first company to really do that will go bankrupt before shipping the next generation of devices.

The same way it is calculated for rotating platters, I would guess.

The lab sets up a test with 1000 drives for 1000 hours. If one drive failed during the 1000 hours, the MTBF will be advertised as 1,000,000 hours ([1000x1000]/1). [short time period] * [number of pieces tested] / [number of pieces tested which failed within that time period] = MTBF.

He may not have lied...

I usually ask a variation of that question... What's something you see about yourself as a potential weakness for this role?

The question is open enough that you don't need to pick your worst weakness. I actually don't really care about the potential weakness, I expect the candidate to be mature enough to be honest/candid and to come up with an improvement plan or a way to work around the weakness. Answering "I don't have any weakness" is usually a sure way to be put in the circular filing device.
