Comment Solved with a "smart" power strip (Score 1) 394

My power company solved this problem for me by shipping out (at no additional charge) a power strip with 1 master and several slave outlets. The TV is plugged into the master outlet, and everythign else into the slave outlets. When the TV is off, the slave outlets are automatically switched off. So regardless of whether the cable box / dvd player / name your random device would prefer to live in standby mode, it can't. Sure, there is a 20 second delay when I turn the TV on while the box syncs itself back up with the network, but that's a small price to pay.

No, my original statement was unclear. I was not attempting to classifly economists with social scientists. I was stating that they are both a long way from physicists. Perhaps 'fundamental science' is a better term for what I'm willing to call science. FWIW, that excludes large chunks of stalwarts such as biology & geology.

That actually was part of my point. In my day job (and night job and weekend job, and, oh god I need a vacation) I'm an astrophysicist. I have more data sets that I can recall, and the number of problems for which I'm confident that the errors are Gaussian is at most 2 or 3. We're finally in an era where computational power facilitates forward modeling & Bayesian techniques that can provide good estimates of true uncertainties. But I (and many of my colleagues) barely understand how they work. Any expectation that most researchers are willing to invest the time to understand anything beyond Gaussian statistics is unrealistic.

+1 this. The problem here is the author's impression that "social scientists" and economists are scientists. The groups that he excludes in the first paragraph (physicists) are scientists. Anyone attempting to implement a statistical model designed for a large (and Gaussian) data set on a small number of data points (as the article's example does) should expect to get an answer that is at best marginal. Any scientists who ever received even the most basic of statistics and/or data analysis training knows this. Understand the problem first, then take enough data points, then carry out your statistical analysis & formulate conclusions.

Comment Why 15,000 ft? (Score 1) 113

My run of the mill thinkpad has operated at the summit of Mauna Kea (~14,000 ft) many times. I've personally also used a Gateway laptop, and a couple of seagate 2.5" harddrives up there. I know of many people who have used other laptop models there as well, and have never heard of any problems. The pressure difference between 14000 ft and 150000 ft is only about 15%.

I strongly suspect Dell just pulled the 15,000 ft number out of their rear because some marketing person thought it sounded neato.

If this airport only serves a few dozen people each day, how can they possibly have passenger flow problems?

Until I read your post, I envisioned someone watching a computer screen with thousands of little dots overlaid on a floorplan of the airport, and saying something like: "Congestion at security line 6, open 2 more lines", or something like that.

If there are only a few dozen people using the airport, I don't see how anyone can interperet this as anything except 'big-(Hungarian)-brother'
