Comment Fascinating (Score 1) 219

One the one hand, this would be a very new business for Valve, even given their previous experience, which means it's a big risk. On the other hand, it seems like it's been impossible for Valve to not make money these days. Fun! I would love to see someone shake up the gaming hardware market, and they're certainly in an interesting position to do so.

Comment No longer vocalizations (Score 3, Informative) 173

For reference, 0.189 Hz is roughly once cycle per five seconds. Take a finger and raise it for 2.5 seconds, then lower it for 2.5 seconds.

This doesn't count as anything more than discrete pulses. I understand that the muscles controlling his vocal folds are performing similar activities to singing, but this is not sound anymore.

has to mean 200,000 gigawatts per hour

Oh my. I really hope this was a troll, but I'm going to bite anyway. If not, know that you are in good company; most people struggle with the idea that watts already include "per unit of time". http://en.wikipedia.org/wiki/Watt

Of course, this is from the same person that wishes the power company would stop using kilowatt-hours to report my electricity usage and start using kilo/mega/gigajoules.

That being said, you may have some legitimate arguments if you have the units straightened out.

Comment Kind of missing the point. (Score 1) 1127

This sounds like a "5 to 10% tolerance" policy instead of a zero tolerance policy. Maybe I'm just overreacting, but anything that suggests to the guys that sexual harassment is just kind of wrong is missing the point.

Here's an idea: Get some fun, simple ideas for a solution from a group of women. That should get you pointed in the right direction.

Brain Scan Can Predict Math Mistakes 133

itwbennett writes "Computer Science Ph.D. candidate Federico Cirett says that he can predict with 80 percent accuracy when someone is about to make a mistake on a math question. Using an EEG machine, Cirett can identify the patterns in a volunteer's thinking that are likely to result in an error 20 seconds or so before it's made. 'If we can detect when they are going to fail, maybe we can change the text or switch the question to give them another one at a different level of difficulty, but also to keep them engaged,' Cirett said. 'Brain wave data is the nearest thing we have to really know when the students are having problems.' He will present a paper on his findings at the User Modeling, Adaptation and Personalization conference in July."

I'm glad you asked for the citation. After tracking down the source, it turns out my statement was slightly misleading and I get an opportunity to correct it. I apologize. Also, it pisses me off when other people make claims like this without backing them up, so I get to eat my own dog food.

A more accurate statement: 75% of health care costs in the U.S. are due to chronic conditions, and the chronic conditions that are due to lifestyle choices dominate this category.

Comment Obesity (Score 2) 504

75% of money spent on health care in the U.S. is for self-inflicted diseases or the consequences thereof. That might be a good place to start looking.

I'm not saying that people that need dialysis or bypass surgery shouldn't be helped; I'm saying we should be spending money on ways to help them not get there in the first place.
