Comment Re:New Perspective (Score 1) 457

They were bad. The deleted scenes from Episode II actually make it a much better film - basically, anything establishing characters was deleted. The film could have easily lost some of the gratuitous action sequences (e.g. most of the factory-with-flying-R2D2 scene) and kept the plot and character development if length was such a concern.

Comment Re:Why have an exhaust port at all? (Score 3, Insightful) 457

We're not just in science fiction land, but in movie fiction land where things don't have to make sense, but...

In space, one of the most difficult things to do is dissipate heat. You can radiate, but you can't convect or conduct heat away from you. For a practical demonstration, get a vacuum flask, fill it with boiling water, put it in the freezer and see how long it takes to cool down.

The Death Star has a massive laser-of-doom weapon, which almost certainly produces a huge amount of waste heat. Dumping that heat is likely to be a priority, because you want the planet you're shooting at to be destroyed, not you. Being able to vent coolant in large amounts quickly from the middle of the station is probably very important.

Comment Re:Car driver ethics: What do I hit? (Score 1) 800

The whole assumption that we should be discussing this for autonomous cars is a bit bizarre. There are millions and millions of cars driven by people, so we should discuss for them first.

As the summary says, you typically don't have time as a human to make a conscious rational decision about what to hit in a collision. In contrast, an autonomous car can do a lot of processing in a tenth of a second.

And the article is a bit stupid because it forgets a few things: One, a crash with a bigger car is worse _for me_

Not necessarily. A larger car can have bigger crumple zones. If its crumple zones are twice the size of the small car, then the acceleration that you'll experience in the collision is a lot less and so there's a greater chance everyone will survive (assuming that the relative impact speeds will be the same).

Second, it's unlikely that two other drivers made mistakes simultaneously, so it would make a lot more sense to crash into the car whose driver caused the problem

That contradicts your first point. Are you using your car as a weapon to punish the guilty driver, or are you using it as a means of ensuring your survival? It's quite likely that it would be better to swerve into a car travelling in the same direction as you that hasn't made any errors to avoid hitting an oncoming vehicle that is doing something stupid (like being on the wrong side of the road). The relative velocity of the impact will be considerably less.

Comment Re:To the URLbar! (Score 1) 92

Privacy issues aside, it's also a UI disaster. Previously, I could switch from URL mode to search mode by hitting tab. It became a reflex - create new tab, focus is in URL bar, hit tab, type search term. It took several months to unlearn that bit of muscle memory. And now, rather than a key press that takes a fraction of a second, I have to rely on some flakey NLP code to determine whether I want a search or a URL. I significant amount of the time, it decides that my search term is actually something that wants to be autocompleted to a previous URL that I've visited, so I end up going to a random site. Or it decides that a search term with a dot in it (try searching for command.com) is a domain name, doesn't find it, and then searches a load of similar things and delivers me to a different random page. I've now got into the habit of hitting space at the end of every search, so it now uses exactly the same amount of key strokes for me as the old design in the best case and is less reliable.

Comment Re:Blank Media (Score 1) 477

I've found it very much depends on the content. if you know there should be detail visible in a scene, you will notice the additional details you can actually see in high def. An example i posted earlier was a concert I have on HD-DVD which showed people in the crowd filming with their phones. You could pick out details on the screen of their device with HD-DVD. No way in hell would that be possible in standard 480p.
