Hydraulic Analog Computer From 1949

Fungii Re:Computers can't model macroeconomics (184 comments)

I don't see how anything you've said implies that computers can't model macroeconomics. The kind unstable behaviour you're describing certainly limits the accuracy, but instabilities can definitely be predicted too. It's not as futile as you seem to be making out.

And another thing - people's sense of wealth and understanding of risk isn't something that should need to be modeled, those two things would be something that you would infer from the results/state.

Researchers Store Optical Data In Five Dimensions

Fungii Re:Silly question (239 comments)

Actually, that was me.

What?

They reported on what they did. Multi-wavelength light is commonly used in fiber optic communications to provide multiple channels on a single strand.

Yes, but this isn't as simple as that, the nanorods have been designed to respond to a few specific frequencies, optical fibers are inherently transparent to a wide band of continuous frequencies.

Polarization is a radial angle rather than a hor/vert thing. This is the first iteration. We should not expect everything in the first go.

I understand what polarisation is.. do you understand what linear independence is?

Fungii Re:Silly question (239 comments)

No doubt. I think their choice to label colour and polorisation as continuous dimensions is a little bit misleading though.

Researchers Store Optical Data In Five Dimensions

Fungii Re:Silly question (239 comments)

Yes, but not as carefully as i should have it seems..

So yes you're right about how they are labeling dimensions, but what I was saying about there only being two usable polarisations and a small number of frequencies is still true - it's not really continuous because it's limited by the materials.

Researchers Store Optical Data In Five Dimensions

Fungii Re:Nope (239 comments)

I'm not sure what you're saying nope to.. I was just using horizontal and vertical dimensions as an analogy because that's the one people are most likely to be comfortable with.

For polorisation you're mistaken - if you are adding light in 45 degree polorisation increments you won't be adding another dimension because it won't be independent of the horizontal/vertical polorisations you are already using - light can't be both horizontally and diagonally polorised without being automatically verticularly polorised. Length width and depth aren't dimesions of this system either.

They can add more dimensions by adding more colours, but it's not unlimited. There are only so many colours that the materials they are using can store independently. You could think of it in terms of each of the colours being a harmonic of vibration of the gold nano wires they are using, so like the harmonics of a string usable frequencies are going to run out pretty fast.

Researchers Store Optical Data In Five Dimensions

Fungii Re:I count 6 dimensions not 5 (239 comments)

Hmm... why are they calling it 5? Am I missing something?

Yes - the dimension of the system is just the number of independent variables, the 3 wavelengths and the 2 polorisations.

Think about it in terms of a 1D line vs a 2D plane. In the case of the line there is the less than 0 and greater than 0 regions. When you move up to a plane there are two new greater than 0 and less than 0s (in the y plane as opposed to the x plane of the 1D line, say). So you have 4 possible combinations (or quadrants in the plane) in 2 dimensions.

Also - note that light which is circularly polarised is both vertically polarised *and* horizontally polarised, so you can have unpolarised red light; vertically polarised red light; horizontally polarised red light and vertically and horizontally polarised red light.

(Similar to: just red light; red light and blue light; red light and green light and red light blue light and green light)

Successful Launch of ESA's Herschel and Planck

Fungii Re:Another Job well Done (121 comments)

Flaws? Well, for a start there's the fact that it's completely ridiculous...

Any fuel to be used for refueling would have to be launched with the craft - it all has to come from earth anyway so there's no benefit to be gained. It doesn't make any sense, it's just adding in an unnecessary layer of complication.

Even apart from that, a docking at the L2 point in order for the refueling would be a ridiculously complicated process - some kind of automatic system could be designed to do it, but (unless the craft's final destination is the lagrange point, in which case it obviously isn't going to need refueling) that would waste a lot of fuel in order to stop the craft so that it could dock with the tanker.

And the orbit of the craft to be refueled would have to pass through the lagrange point which in almost all cases would waste more fuel than could possibly be gained by the refueling (this is assuming that a transfer orbit through the lagrange point is even possible).

Could the Internet Be Taken Down In 30 Minutes?

Fungii Re:YAH!! (289 comments)

Oh, I don't know.. maybe it could have meant the ability to survive a single point of failure?

Could the Internet Be Taken Down In 30 Minutes?

Fungii YAH!! (289 comments)

Survivability.. so maybe

All it was designed for was to survive a single point of failure.

(note that I'm quoting canajin here in case there is any confusion)

What makes you think survivability implies the ability to survive nuclear war? The fact that you've heard as much parroted anecdotally countless times in the past?

Open Source Shooter Nexuiz 2.5 Released

Fungii Re:Not Very Impressing (309 comments)

That out of the way, your complaint is totally invalid.

What? How can a compliant be "invalid"?

The amount of work that's gone into the development is completly irrelevant, so there's no need for your snide remarks about 'some guy who plays the latest console releases - the fact of the matter is that this shooter isn't a patch on commercial games from 10 years ago, as is the case for most open source games.

Now, excuse me while I go for a game of tux racer.

Want a Science Degree In Creationism?

Fungii Re:This is not a bad idea (848 comments)

By bringing serious study and research to this field, we can shed light on it and evolve the field to be at least in line with current scientific thought.

Creationism fundamentally conflicts with scientific thought, there is no light to be shed - creationism isn't a field of science with discoveries to be made, it is one theory with absolutely no supporting evidence.

Packing Algorithms May Save the Planet

Fungii Packing algorithms don't just apply to shipping (195 comments)

Something the summariser seems to have missed.. This kind of problem comes up in a lot of different places.

One example would be brain tumor treatment using lasers.

ISS's Node 3 Might Be Named "Colbert"

Fungii I'm just glad that (276 comments)

Slashdot is maintaining it's journalistic integrity, even with the threat faster moving and more distracting spam filled sites like digg and reddit.

Seriously, it's refreshing to know that at least when an article does get published on slashdot it will be newsworthy.

Which Distro For an Eee PC?

Fungii Re:Xubuntu (466 comments)

I'm the same, I've got Xubuntu and compiz running and it's perfect, get some minimal window decorations and you're sorted.

Just do a standard installation, then head over to http://www.array.org/ and follow the instructions to install the kernel which will get your wireless and hotkeys working.

http://www.eeeuser.com/ is an excellent forum if you have any more questions. There are a few threads there that have step by step guides to installing and configuring Xubuntu, but there really isn't much to it beyond getting a custom kernel.

Facebook's New Terms of Service

Fungii User Content - definition? (426 comments)

How exactly do they define "User Content"? It seems that's pretty important.

Also - how well do these draconian EULAs hold up in court? Has there been a landmark test case yet? If their definition of "User Content" is a log of absolutely everything the user has uploaded/done then surely this must infringe on the user's right to privacy.

Post-Beta Windows 7 Build Leaked With New IE8

Fungii There have been a lot of leaks of Windows 7 (332 comments)

Who's leaking the builds?

Either way, Microsoft are getting a lot of good free press from them so far, I don't think they'll really have to worry about piracy cutting into their profits too much.

Darwinism Must Die So Evolution Can Live

Fungii Exactly (951 comments)

He adds that nobody talks about Newtonism or Einsteinism

No one talks about "Darwinism" except the creationists. The reasons he gives are exactly the reasons they invented the term - it's far easier to discredit a dead guy from 100 years ago than it is a scientific concept.

By making it seem like the work of one man with millions of blind followers it appears more fallible.

Their tactics are pretty ironic really.

The Deceptive Perfection of Auto-Tune

Fungii Re:Authenticity (437 comments)

I actually agree with what you're saying, but I think you're off the mark in this case - you talk about true creativity falling outside the lines occasionally, but in pop music autotuners are used to turn every vocalist into a robotic, pitch perfect singer. What T-Pain is doing is creative, he's going for an original sound but for the most part autotuners are the antithesis of creativity.

Fungii writes "This looks interesting, apparently an irish firm has found a way of creating energy from nothing. Apparently they have 'developed is a way to construct magnetic fields so that when you travel round the magnetic fields, starting and stopping at the same position, you have gained energy'. I'm very sceptical, but they are challenging 12 scientists to verify their claims. Could be one to watch."
