Comment Re:Those daring men in their quantum pushing machi (Score 1) 392

He throws out some tentative numbers at the end of the abstract on the requirements for using this principle to manipulate satellites. Anyone here with a solid understanding of physics want to take a stab at working out what the energy input->force output is like assuming a magneto-electric constant of 10^-4 and the particles comprising 50% of the total object mass?

Comment Novikov self-consistency (Score 5, Interesting) 194

This whole 'theory' really just sounds like an application of the Novikov Self-Consistency Conjecture to particle physics. The short version is: the probability of events which could lead to a violation of causality is zero. So, according to this conjecture if the manifestation or observation of the Higgs Boson eventually lead us to develop technology with which we might otherwise violate causality, we'll never discover it.

I can think of at least one way it might - the Higgs Boson is critical to our understanding gravity. We know from relativity that there are certain gravitric structures which might potentially lead to violations of causality. One example is a toroidal singularity, spun extremely fast, which theoretically generates stable artificial wormhole along the axis of the spin with an opening small enough to fire, say, an x-ray laser through. A signal sent through such a wormhole and then back again could lead to extremely clear-cut violations of causality.

Thus, if the Novikov Self-Consistency Conjecture is correct, the discovery of anything capable of allowing us to engage in large scale gravity manipulation of this sort might well have zero probability of ever occurring.

I don't really believe this is what's going onhere , but given the abject failure of every experiment that might lead us to real, large-scale gravity manipulation (I'm thinking of that experiment where extremely fine measurements of lasers fired down long tubes buried under the ground were supposed to be used to detect gravity waves), it's a neat idea.

The speed of Light can be violated (i.e., there are hidden states that can exchange information faster than the speed of light). This implies, by the way, causality failures would be possible, so that in principle you could do something like kill your grandfather and prevent your own existence.

Not necessarily. One possible alternative is the Novikov Self-Consistency principle, which posits that if a faster-than-light communication or a classical 'time travel' ever did occur, the probability of those events violating causality would be zero. Some undefined sequence of events would always prevent any attempts at violating causality from ever succeeding. Time travel or faster than light communication events might even be fixed within the timeline and actually be *required* of the participants.

It's just a bonghit, but an interesting one. Within Copenhagen Many-Worlds it could, for instance, be interpreted along the lines of the Anthropic Principle: universes which *would* contain causal paradoxes cancel themselves out entirely, leaving only universes in which no such paradox managed to occur.

Comment Re:Edison? (Score 1, Interesting) 124

But even with Tesla aside, this isn't new... it's just not as vastly useful as people re-discovering it seem to think it is. It doesn't work over gigantic distances, only moderate ones, and there's no engineering you can do to get around that.

The misunderstanding a lot of people have is that they think Tesla was chasing *truly* wireless power - when in fact this was probably never his goal. Tesla was always chasing after something he called "longitudinal waves" in an attempt to perform worldwide "wireless" power transmission - he even called one of his companies World Wireless.

Tesla certainly wasn't foolish enough to believe this distance was possible with purely wireless transmission, but instead investigated single-wire transmission systems using the ground as the single wire. His initial success at single-wire transmission was at Colorado Springs in 1900 with three lightbulbs in a closed circuit loop with no power source and a transmission source a hundred feet away. In this experiment, as in his later vacuum tube powering experiment performed at considerably greater distances (eventually miles away), the objects in question were always had a metallic contact with the ground.

Take a look at figures 3, 6, and 7 on this page: http://amasci.com/tesla/tmistk.html. This seems the most likely explanation for the experiments at Colorado Springs and Wardenclyffe. Wardenclyffe in particular is where we find Tesla sinking iron rods 300 feet into the ground, burning out local power station dynamos with his energy demands, and constructing a massive omnidirectional transmission tower.

The reasonable conclusion from all this is that Tesla was always pursuing single-wire transmission schemes in which literally the entire Earth itself was the single wire, and the transmission medium for the wireless component was the entire ionosphere. "World Wireless" seems to have been meant quite literally, which was in keeping with all we know about Tesla's personality. Unfortunately, as we all know, Tesla needed something like an order of magnitude more funding than JP Morgan was willing to provide - particularly after Marconi.

Beyond that, though, Morgan would have probably pulled the project even if Tesla had gotten it working: if single-wire worldwide transmission was in fact his intention, it would've been impossible to meter consumption on a per-user basis.

That's the most damning thing about this - myself and several friends have used Zicam heavily over the past year. It *really* works if you're in a super-high-stress job that exposes you to a lot of colds/flu (med student, floor trader for a brokerage, constantly traveling for business, etc.).

I got a vicious cold last weekend and would not be traveling right now if it weren't for the stuff, and the universal reaction from the group of people I just IM'd to make sure they knew was, "Crap... it's *almost* worth it."

It's not almost worth it, of course, but the one thing I'll say for Zicam is that it definitely does what it claims to do.

Damn.

Comment Detection via delta? (Score 2, Interesting) 334

Couldn't you perform the detection by measuring the delta of the state?

On booting Windows 95, attempt to read from the floppy drive. If there's no disk, then take whatever that hardware state is - whether 1 or 0 - as the 'base' value, and periodically check to see if that value has changed.

I may be missing something but it seems like the appropriate trigger isn't the specific value of the flag, but rather the setting of said flag.

Analyzing Microsoft's Linux Lawsuit 297

jammag writes "Open source advocate Bruce Perens takes a close look at Microsoft's lawsuit against TomTom (discussed here last week), which involves an implementation of the Linux kernel, and calls it essentially a paper tiger. He notes: 'the technologies claimed in the 8 patents involved are so old and obvious that it's fair to say they have a high "Duh!" factor. There's an anti-trust angle to this suit that could blow up in Microsoft's face. And there's a high probability that some or all of the patents involved are invalid, due to recent court decisions.' Although the legal expense for TomTom to defend itself in court could be astronomical — meaning they may be forced to settle — in Perens' view Microsoft is aware its case is weak, yet hopes for a PR victory at limited cost." And reader nerdyH adds speculation from Open Innovation Network CEO Keith Bergelt that Redmond's action could be retaliation for TomTom's spurning a Microsoft acquisition bid in 2006.

Actually, given the relative power of the two factions over time and BoB's level of entrenchment in very rich, very central parts of the gamespace, a better analogy might be Google taking down Microsoft through the same methods. I stopped playing EVE three years ago and even I had to pick my jaw up off the floor when I read this news. BoB was *THE* all-pervading massive enclave of successful assholes in the game, and despite recent losses were still the largest power. Unbelievable.

Comment Re:It's a Job (Score 5, Informative) 254

Here's my experience:

A year before Bioshock shipped, I applied for a QA position at Irrational Boston. After five years of unemployment, I still have no idea why they hired me, but I wasn't about to argue. Fast-forward three months in QA, some game balance analysis writeups I'd done caught Ken Levine's eye and gave him the impression I was quasi-literate. For my part, I simply didn't have the heart to correct him.

A month later I was working fulltime on script proofing, then editing, story structure, helping direct voiceover recording sessions, and finally voiceover production (take selection & compositing).

So, some tips:
1) Get a QA position at a development studio where you are actually working hand in hand with the developers. Do NOT get a QA position at a publisher's degenerate nerd stockyard - busing tables or suicide would be preferable to that.

2) Get your foot in the door any way you can, no matter how low or menial you have to start, and once you're inside show them what you're capable of. Without pissing off your manager.

This is a young industry, there's a lot of movement potential if you've got the chops. Get out there and amaze people.
