P vs. NP Problem Linked To the Quantum Nature of the Universe

NexusJedi Re:Computable? Simulatable? (199 comments)

I don't think the assumption was that the universe "solves" the equation to "compute" reality. Rather, I think the point was that the "breakdown" of quantum behavior into macroscopic behavior seems to happen around the same scale that the interactions described by Schrödinger's equation start to run into fundamental limits of computability in the form of the Planck Length, and that this can help "explain" the transition to macroscopic behavior as simply being the point at which the system becomes too complicated, in a fundamental complexity theory sense, for Schrödinger's equation to accurately describe it any longer.

Climate Treaty Negotiators Are Taking the Wrong Approach, Say Game Theorists

NexusJedi Re:All well and good... (227 comments)

Distribution (a.k.a. land area or population density) probably plays a large role in the disparity. Europe has a much smaller land area than the US. It would be interesting to see emissions stats per capita adjusted for land area.

'Instant Cosmic Classic' Supernova Discovered

NexusJedi Re:Astounding! (141 comments)

Neither am I, but I'm having to deal with a lot of time and space recently.

Tell me about it. Seems like I've been dealing with time and space forever. No matter where I go, all hours of the day, it's time and space! Even on the weekends, time and space! I just can't get away from it.

Nexus One a Failed Experiment In Online Sales

NexusJedi Re:False (366 comments)

Yeah, for the most part TMO has really great customer service and plans. But coverage depends heavily on your area. I live in Gainesville, FL and I get "3G" coverage that caps out at around 750Kb at full bars, and much of the city doesn't have coverage at all. When I was in Austin recently, tho, I was getting upward of 4Mb rates. I think they're much better on the west coast. I really wish it were not the case, but I will probably have to give up my N1 and switch to another carrier with decent data rates and coverage here.

Underwater Ocean Kites To Harvest Tidal Energy

NexusJedi Re:Sea kites for space travel (203 comments)

If NASA times it just right, we could put people on the moon, launch the moon at Mars and have people walking on Mars just months later.

...

Next, we use the tide from the sun to travel to Alpha Centauri.

Wait, are you suggesting that we ride the sun to Alpha Centauri, or put kites in the tides on the sun caused by Earth and launch Earth toward Alpha Centauri?

Can Curiosity Be Programmed?

NexusJedi Re:Self referential (269 comments)

The recent joke, however, will never be novel or funny again.

This fails to explain running gags. Even regular jokes are, in fact, often funny again (even if no longer novel).

IT Job Satisfaction Plummets To All-Time Low

NexusJedi Re:Perhaps... (453 comments)

No, I'm not saying every system would die within two weeks without maintenance, but enough of them would that it would create som real freaggin' huge problems! Not to mention the user's need to be led by the hand through the nigh unfathomable maze that is finding files you've saved, finding the right icon to click to launch the application you use every day, sending e-mail, etc.

It occurs to me that this points to most IT systems (particularly interfaces) being poorly designed.

Huge Unidentified Organic Blob Floating Around Alaska

NexusJedi Re:The real question (424 comments)

Over the past 10 months, five feet have been found on shorelines along the Strait of Georgia, southwest of Vancouver. ... Four of the feet are right feet. The fifth is a left foot. ... There are more than 2,000 people missing in British Columbia alone, says Ebbesmeyer, so there's a good likelihood that they come from one of them.

One of the missing people had 4 right feet and a left foot? And I thought I was bad at dancing...

Reflected Gravitational Waves

NexusJedi Re:"Indentation in rubber sheet" (329 comments)

I find this a better analogy:

Picture a rubber sheet with a grid of parallel lines drawn on it. These lines represent the trajectory of objects moving along straight paths. An object with mass causes the sheet to shrink in toward the object in all directions, causing those parallel lines to curve in toward the object as well, and consequently the paths of traveling objects to curve in toward the object as well. (The stretch [pun intended], of course, is that the traveling objects are constrained to follow the lines, but you have to realize that the objects are not rolling along on top of the sheet, but are in fact moving within it.)

Extend this to three dimensions, and you have gravity. Now the only thing to determine is why objects warp space, and that is beyond my ken.

Android Gathers Steam Among Open Source Developers

NexusJedi Re:Wow (176 comments)

The G1 was released in October of 2008, yet they still had 70% of the number of project releases that the iPhone had in 2008. 70% as many OSS projects in a quarter the number of months.

(Granted, the SDK was available for longer, but still very few people, developers included, actually had a phone; they were excited enough about it to develop apps solely on the emulator, without being able to actually use them until October.)

Dark Energy May Lurk In Hidden Dimensions

NexusJedi Re:Well... (164 comments)

Negative energy has some bizarre properties.

Yeah, for one thing, it heals undead. Obviously, this means that string theory is just a conspiracy perpetrated by vampires.
