Comment Many engineering hurdles (Score 5, Insightful) 35

It seems like this is more in the gee-whiz category than anything practical and they seem to have the class more because it is cool than because they expect this to happen anytime soon. A few parts of the article stand out:

"Think about how much space you need in a typical house today, and how much of it you use at a given time," Olds said. "If the house could dynamically reconfigure itself to match your daily routine, you could find yourself being much happier in less space and using less energy. For example, a room could be configured as an office during the day, with a media wall that is used as a business display. But at night, it could be a living room, and then it could transform into a bedroom."

But much of the rest of the world outside the US has much smaller houses already. People here have massive houses not because they need to but because they apparently want to. This is especially true in the suburbs where the rooms are often much larger than they need to accomplish their goals. Large houses are status symbols and the size of American houses has little connection to what is practically necessary. Maybe this might work better in Europe or if it were restricted in the US to urban centers? The article also acknowledges problems with other ideas, such as how they discuss modular bathrooms but then acknowledge that getting all the pipes and the like to fit would be difficult. And nothing here even begins to touch on the many issues there would be with building codes.

Comment The most interesting thing is what it looks like (Score 4, Insightful) 463

I've never played Eve Online and have no intention of doing so. But I'm continually fascinated by how cool the space battles look. Essentially we have a computer game today where the unchoreographed battles look better than the space battles made using special effects from the late 1980s. That's an amazing testament to how far the technology has come.

the horsepower per hour of engine life? That thing looks like it'll last 20 hours before it needs rebuilding.

A point the story ignores. Any idiot can get buttloads of power out of an engine if it doesn't have to do so for very long. Two-stroke engines are particularly good for this if fuel consumption and exhaust emissions are minor considerations.

Comment The actual paper (Score 5, Informative) 458

The actual paper can be found here: http://arxiv.org/abs/1401.5761. People have suggested informally ideas somewhat similar to this one before, but Hawking proposal seems to actually have the math behind it. Possibly most importantly, he can show that his predictions are a consequence of gauge/gravity duality http://en.wikipedia.org/wiki/AdS/CFT_correspondence. This suggests that this may be a testale consequence of certain string theories if one could observe a black hole under the right conditions and see that it only was pretending to be a black hole.

Yeah, I was surprised by that. When I was on OKCupid my rate of getting a second date if I got a first one was greater than 50%. It may indicate that he's picky in ways that aren't easily described in the OKCupid system, but your point is well-taken. That particular statistic is evidence of systemic failure (although the 91 v. 99 is not).

Yes, but it wasn't clear if that was because you actually understood that the individual had a decent relationship going on or was just further snark. More seriously, As far as I can tell from the article the main problem with his method was a poor signal to noise ratio which was made worse by the large number of candidates. The signal to noise ratio on online dating is always terrible, but it would be more noticeable when one has a larger pool. In fact people optimize profiles all the time (which hobbies they emphasize, which pictures of themselves they present, etc.). But somehow when one optimizes more effectively relying not on vague intuitions but actual data, then people have reactions like yours. (Possibly relevant disclaimer: I met my girlfriend on OkCupid. I did not do what this guy did.)

Comment Define "convenient" (Score 2) 201

My biggest scope is an 18" dob, made by the now-defunct Starsplitter. It looks a lot like an Obsession 18", and uses Obsession accessories.

While large, with the wheelbarrow handles it's easy to move around and set up. When I bought it I refurbished it, including redoing the teflon bearings in the mount. A local industrial plastics shop sold me an offcut of real virgin GE sheet teflon. The result is pure dobsonian: rock steady, stays where it's pointed. And perfectly balanced: it moves with one finger.

Jupiter's moons are different colours and are non-stellar. Titan is an interesting colour. M13 has a friend, NGC 6207.

Comment Never drove that much to begin with (Score 1) 635

As a city dweller public transport and the occasional rental car were all I needed for a long time.

A few years ago I got a nice bonus from my employers and bought a little car to see what I might do with it. I can't say it's changed my driving habits all that much: I still take the bus to work, but drive on weekends. The price of gasoline is certainly a factor, but will have to be quite a bit more before I cut back further on driving. I'd love to drive an electric car, but the infrastructure isn't there. I live in an apartment and have nowhere to plug one in, despite numerous discussions with the building management.

There are a few destinations around here (like downtown Vancouver) where I still prefer to take the bus, because the traffic and parking are impossible.
