Is That Dress White and Gold Or Blue and Black? 358

Posted by timothy

HughPickens.com writes Color scientists already have a word for it: Dressgate. Now the Washington Post reports that a puzzling thing happened on Thursday night consuming millions — perhaps tens of millions — across the planet and trending on Twitter ahead of even Jihadi John's identification. The problem was this: Roughly three-fourths of people swore that this dress was white and gold, according to BuzzFeed polling but everyone else said it's dress was blue. Others said the dress could actually change colors. So what's going on? According to the NYT our eyes are able to assign fixed colors to objects under widely different lighting conditions. This ability is called color constancy. But the photograph doesn't give many clues about the ambient light in the room. Is the background bright and the dress in shadow? Or is the whole room bright and all the colors are washed out? If you think the dress is in shadow, your brain may remove the blue cast and perceive the dress as being white and gold. If you think the dress is being washed out by bright light, your brain may perceive the dress as a darker blue and black.

According to Beau Lotto, the brain is doing something remarkable and that's why people are so fascinated by this dress. "It's entertaining two realities that are mutually exclusive. It's seeing one reality, but knowing there's another reality. So you're becoming an observer of yourself. You're having tremendous insight into what it is to be human. And that's the basis of imagination." As usual xkcd has the final word.
It would make the comments more informatively scannable if you include your perceived color pair in the title of any comments below.

Its been proven time and time again that red light cameras do more harm than good.

And the opposite has also been proven:

"Crash effects detected were consistent in direction with those found in many previous studies: decreased right-angle crashes and increased rear end ones."

(Right-angle crashes are much more dangerous to the occupants than rear end crashes, so exchanging the former for the latter results in a net improvement in safety.)

To further improve the safety of red-light cameras, consider that almost all rear-end collisions are caused by people tailgating. If each red-light camera were turned into a combination red-light and speed camera, people would slow down when approaching intersections, so someone slamming on their brakes at the last minute would be less likely to be hit from behind.

Ask Slashdot: Are General Engineering Skills Undervalued In Web Development? 323

nerdyalien writes After reading a recent post about developer competence, I can't help but to ask the question, "Are general engineering skills undervalued in web development?" I am an EE major. The course I completed, and the professors who taught it; mainly emphasized on developing skills rather memorizing reams of facts and figures. As a result, I have acquired a multitude of skills such as analytical, research, programming, communication, project management, planning, self-learning, etc.

A little over 3 years ago, I made the fateful decision to become a web developer in a small SME in SEA. Admittedly, I have an unstructured knowledge about CS theory. Still, within a short period of time I picked up the essentials of web development craft, and delivered reliable web applications. Most of all, I made good use of my existing technical/soft skills, despite the lack of my CS pedigree.

Recently I went through a couple of job interviews in MNCs, SMEs and start-ups alike. All of them grilled my CS theory or Java knowledge. Almost no interviewer asked me about my other skills (or past experiences) that could be helpful in the developer position. In my experience, web development is a cocktail of competing programming languages, frameworks and standards. Rarely a developer gets exposed to a single technology for a substantial period to learn it inside-out. Even still, in web development world, deep in-depth knowledge in anything will be outdated in few years' time as new technologies roll out. So, what matter's today? Knowledge on a particular technology or re-usable engineering skills ?

ALL Taxes are regressive.

A revenue-neutral carbon tax would be quite progressive. If the tax were $1 per gallon of gasoline, and if the average person used 500 gallons of gasoline in a year, everyone would receive a $500 tax rebate every year. For a poor person, that's a lot of money. And since the truly poor don't drive, they won't be the ones paying the tax in the first place.
