You have to be a special kind of idiot to ignore the general success that HSR projects have had across the world. CAHSR isn't a perfect project, it's plagued by politics and would probably cost a fraction of the price if they didn't have to get buy in from 51% of the State.

But profitable? Why wouldn't it be? Acela Express, a relatively crappy HSR system that manages an average speed of 70mph gets half a billion dollars a year in revenues, an amount that's still increasing year-on-year. It has around 80% of the Air-Train market it serves.

There's no reason to believe that CAHSR, a faster "purer" system, wouldn't make more money than Acela Express. And the infrastructure doesn't have to be limited in use to just the four stops currently covered.

It's not perfect, but don't let perfect be the enemy of the good enough. I'd prefer a private project, but looking at the progress of the all-private All Aboard Florida in Florida, I'd say the problems with politics fucking everything up and virtually coercing good projects to do crappy things are going on there too. Texas's HSR is similarly being attacked by NIMBYs in those areas it passes through but doesn't serve. It'll be interesting to see how all three projects progress.

Comment: &is "teal" blue with greenish tinge or vice-ve (Score 1) 272

... blue and brown. Just now, I opened the Washington Post link on my 24" screen in a sunlit room, and it was clearly white and gold.

Though the sensations are vastly different, brown is really dark yellow. The underlying color of that part of this dress seems to be very near the perceptual boundary (probably just on the yellow side of it). This picture seems to have the dress in a non-obvious shadow, so when it is viewed by someone whose visual system doesn't adequately pick up the shadowing and compensate, it crosses the boundary and appears light brown rather than dark yellow.

Another perceptual oddity is that a very slight bluish tinge to white makes it appear "whiter than white", especially in sunlight or other strong lighting. (I suspect this works by mimicing the differential response of the various color sensors in the eye when exposed to very bright light, though blue may also "cancel out" a bit of the yellowing of aging cloth.) Laundry products up through the 1950s or so included "bluing", a mild blue dye for producing the effect. (It fell out of use when it was replaced by a fluorescent dye that reradated energy from ultraviolet as blue, making the cloth literally "brighter than white" {where "white" is defined as diffuse reflection of 100% of the incoming light}, and which, if mixed with detergent products, would stick to the cloth while the surficant was rinsed away.) I suspect some of the "blueish is brighter" effect is going on here.

When I view the picture straight-on on my LCD display, the light cloth on the upper part of the dress appears about white and the image appears somewhat washed out. Meanwhile the lower half has a bluish tinge. So I suspect the cloth is actually nearly-white with a bit of blue. (Viewed off-axis it's very blue, but the other colors are over-saturated and/or otherwise visibly off-color. So off-axis viewing makes it look more blue and this probably adds to the controversy.)

Another color-perception issue is "teal", a color between blue and green. There are paint formulations of this color that give the sensation of "distinctly blue with a greenish tinge" to some people and "distinctly green with a bluish tinge" to others, even under the same lighting and viewed from the same angle. (I'm in the "slightly-bluish-green" camp.)

The first place I encountered this was on the guitar of the filksinger Clif Flint. (On which he played _Unreality Warp_: "... I'm being followed by maroon shadows ..." B-) ) Apparently his fans occasionally had arguments about whether his guitar was blue or green, so he sometimes headed this off (or started it off on a more friendly levl) by commenting on the effect.

It is a big fucking deal because there are long running threads of economic thought which oppose capitalism yet support free markets, and to conflate the two (and equivalently to conflate socialism with a command economy) creates a false dichotomy between capitalist free markets and statist socialism, ignoring and erasing the possibilities of non-capitalist free markets and non-statist socialism.

Now will ICANN put its foot down

It had better hope so, because giving entire TLDs to specific big companies could easily be the straw that breaks the camel's back in terms of the rest of the world accepting US-led administration of the general Internet. There's plenty of scepticism already, but organisations like ICANN are tolerated because frankly no-one has much of a better idea or wants to take on the responsibility. However, it is not difficult to think of a better idea than letting big businesses rewrite the established rules in arguably the most important address space in the world today for their own benefit.

Nah, he said what happened and suggested people who don't believe him look at the evidence pointing out what persuaded him. That's a fairly normal way of arguing.

Let's be honest here: Gamergate is a hate movement. A few minutes of Googling, watching Twitter feeds, and even spending some time in KIA - the "Clean face" of GamerGate designed to lure in useful idiots, forget 8chan where the actual organization is - shows that fairly conclusively. I've delved in. I've seen major GamerGate figures in the early days promoting stories like "How to rape a woman and get away with it" and "How to break a woman". I've seen major GamerGate figures harass a woman developer who'd had the audacity to fight back against earlier harassment taunting her because her dog just died.

That's why pretty much the entire mainstream media is calling GamerGate a hate group. They're not doing it because some female gamedev had sex with them. They're calling it a hate group because it is.

Perhaps they should be asking for a ".google" gTLD, for that purpose, instead of trying to monopolize a generic identifier.

I was about to suggest the same, but with ".goog", to make it shorter. (Can't think of a less-than-three-letter symbol that points to them as strongly.)

(It's also their stock ticker symbol, so maybe it's not such a good idea - it could cause a land rush and litigation from all the other publicly traded companies.)

It's bizarre hype. The articles I've read have quoted the project leaders as claiming this is the real thing, followed by a claim that it's a small scale prototype to test the concept. Uh. OK. Not what most people would say is the "real thing", but whatever.

I'd be more enthusiastic about the project if it didn't appear to be solely a dishonest attempt to kill a high-speed rail project, by claiming an unproven, non-existent, technology that, if implemented as proposed, would only link up two of the four cities CAHSR joins, has a fraction of the capacity, would have a total travel time (that is, downtown to station to station to downtown) that's longer than CAHSR's, is "cheaper". Amazingly enough, CAHSR would cost much less if it didn't have to do those things either.

Which is a shame because I shouldn't be looking at the ugly agenda behind the project. It'd be nice to see it in isolation, as a concept that could join cities in future.

(gold is FFD700, defined by HTML standards).

HA HA HA! YOU FELL INTO MY TRAP!

Pardon my caps, but I set a lot of these, and they are rarely stepped in so beautifully. That's my fault, of course. But, here we go.

When you hear the name of a color, you think of some color which you associate with that, or a thing which you think of as being that color which actually has a whole texture, reflectivity, depth, etc. But the truth is that the same name is being used right now by a dozen different paint companies to describe a dozen different colors, which are then described in thousands of different ways by the downstream users of the paint. There are some absolute color standards based on elements, oxides of the same and the like, but even those are frequently "abused". The truth, though, is that outside of a small handful of colors, they are not defined by any unifying principle. Your use of the HTML standards is particularly hilariously perfect, I really hope that you meant to put your foot there! Outside of web design, nobody but nobody gives a crap about that. Before that, we had the X rgb.txt file, which nobody outside of X-land cared about, which begat HTML colors by the way, junior. But meanwhile, over in the land of professional color, there were multiple competing color standards including AGFA and Pantone — and there still are.

It's interesting that part of this debate is also over the color "black" because "black" is what you see when you don't see anything, and if any part of the dress were truly black then the photograph would look like an editing mistake. Even the color black is subjective. That should be intuitively obvious to a web designer (who else would even mention HTML colors?) who has to deal with the real-world effects of differing black and white levels all day. I may be sitting at a monitor with 120% color (Adobe gamma) but I don't expect other people to have them. As far as I know, there is no color correction e.g. for Android which is not manual, and then the color adjustments become utterly perceptual.

I suspect that celebs are adept at perceiving the actual color of the dress because they have appeared in so many washed-out photographs.

pretty much every pixel in the "blue" area has a B value about 20%-30% higher than the R or G value. That, to me, makes it about as objectively blue as it's possible to be.

Are you kidding? It's possible to be balanced far more towards blue. But also, gold is not a color. I learned back in my Amiga-using, pixel-editing days that there's a lot of blue in most metallics. I don't know if that's an artifact of what happens to light when it bounces off of them, or what, sorry. Not a physicist. But I know that if you're trying to make something look metallic, you're going to be adding some blue to it.

The XKCD plot just makes me see gold and white at different levels of brightness. But I did find this color illusion featuring yellow and blue. The dogs are actually the same color, which you see if you look at them individually through a small aperture

Make it pretty obvious that at some point your brain switches from wanting to see blue to wanting to see yellow based on the color context. It would appear some of us are slightly different in where transitions like that occur.
