Mostly color perception

Content starts here
The Internet is an amalgam of forms blurred under epistemological pressures. In Søren Kierkegaard’s words, under this flat shower of leveled information, where everybody is interested in everything and nothing is too trivial or too important, people just accumulate information and postpone decisions indefinitely, i.e., nobody takes action and nobody is responsible for truth — there is no mastery, just gossip. He called this the æsthetic sphere of existence, exhorting us to evolve to the ethical sphere, where we do not just accumulate information but take action and make commitments. Blogs are instruments to overcome flatness by creating opportunities for vertical activities. In this sense this blog is a view from my window — a collection of tidbits I judged relevant to computational color science and in general to the promotion of scientific excellence in areas of strategic importance for the future of research, economy and society.

» Your portrait

One of the American strengths in the global economy is the demographic knowledge about itself. No other country publishes high quality statistical data as fast as the US, and nowhere else have companies such intimate knowledge of their customers. Nevertheless, HP's blogs are subject to very stringent privacy rules, and we know very little about You, our reader.

» World Wide Gamma

An experimental tool post to crowdsource the average 'gamma value' for the world wide web. To learn more about gamma you can read the FAQ and also the FQA by Charles Poynton.

Instructions
1. Use '+' and '-' buttons to make the corresponding patches above the buttons lighter or darker.
2. Create a visually equal spaced gray ramp from black on the left to white on the right. That is the jumps in lightness between neighbors should be roughly equal and the ramp should be getting progressively lighter.
3. Click on the 'Plot' button to see your results(black) plotted versus the world wide gamma(red).


Note that users of older versions of Safari (ie 1.3.2) have reported that this post is not interactive, but it has been tested with newer versions of Safari (ie 3.1.1) and the post is functional.

» Research policy update

From time to time I have been posting about the research process itself, i.e., research policy. Today I will just post two links to two other blogs with recent posts on this subject.

Jon Stokes writes on ars technica on paying for secrets: national security versus tech innovation, while Neil Gunther writes on Performance Agora on USA High Tech R&D Trending Down.

» More on print services

My post about print services appears to have caused some confusion. While I prefer to get feedback in the form of comments, so others can also comment and a dialogue is established, here are some clarifications — at the risk of making things even muddier.

» Print services

Computer science — or informatics, as it is called more appropriately in Europe — has a less linear progress history than other technologies. Indeed, many a breakthrough technology was forgotten only to be reinvented several decades later. I had already posted on concurrent programming (in the comments) and color encoding.

» Roaring silence

As I mention in my green description block on the top of this page, I am relating you a view from my window. From the window of my corner cubicle I see the entire Silicon Valley. A little closer, beyond that empty parking lot that is the constant reminder of better times, I see HP's Corporate Headquarters.

» An Online Color Naming Experiment

As part two in a series (part one is here) about the online color thesaurus and the interactive color zeigeist, we should go back over five years to the original online color naming experiment. This simple experiment dates back to the almost web 1.0 days of 2002 and was an unconstrained color naming experiment in English. This was one of the first web-based visual experiments that we tried and given the large number of carefully controlled laboratory studies on the topic of color naming, it seemed like a good place to start. I did decide up front to try to avoid the whole universalist versus relativist debate.

» The ether of knowledge

From the beginning of human kind, populations have given special status to certain members so they perpetuate the population's growing knowledge. We suggest today these people's job has become much more complex and they must also be extraordinary harvesters.

» Income level: economists are wrong

In traditional economic models of decision-making, the most important determinant of individual well-being is the absolute level of income. A recent study based on brain activity observed using functional magnetic resonance imaging (fMRI) proves these models wrong. Indeed, social comparison affects individuals' subjective well-being, and thus behavior.

» Postcard from Albuquerque

In big corporations the hand often does not know where the foot is and then shoots itself in the foot. Now I am finally able to get at my email after my old mailbox was secretly deleted over two weeks before I got access to the new mailbox. There I found a postcard from Albuquerque I would like to share with you. It was sent by John McCann, who shot it on his HP PhotoSmart C945 camera and kindly gave permission to reproduce it in this post.

» The arcane art of leadership gestation

Today I will lift a bit the kimono to give you a glimpse on this aspect of governance. I barely have enough time to stay alive, so I apologize to use a compact European writing style instead of the more eloquent American style I am supposed to use in this blog. The occasion is today's Nobel Prize announcement.

» Mini review. Snakes in suits

This is the third review in this series I am calling 301.7—terrorism @ home, and as promised it is about the workplace. In the previous two reviews we visited The sociopath next door and Without conscience. In science, the Nineties were the decade of the brain, and so much progress was made—think for example functional magnetic resonance imaging (fMRI)—Dr. Hare's latest book, written with Dr. Babiak, gives us a much more precise picture of the psychopath than Without conscience. Yet, there is still no other cure than capital punishment while concomitantly we have made our organizations more inviting for psychopaths.

» A sea change in intellectual asset management

An article senior editor Roger Parloff wrote in yesterday’s Fortune magazine had quite a bit of echo in the blogosphere during the last two days. Recently there have been some other events related to intellectual assets in color science that suggest we may be at the verge of a sea change in intellectual asset management.

» HP Tech Con

This week it is easy to get a good parking spot at HP Labs, because HP’s technical conference is taking place in San Antonio. HP Tech Con, the premiere internal conference for HP’s technologists, brings together a cross-section of technical leaders from a wide range of disciplines from around the company. The conference recognizes some of the company’s most promising work enhances collaboration and visibility for top-tier technologies and continues to be a driving force in the role of technical innovation at HP.

» Stuffing the toolbox

In industrial and government research organizations there are often religious wars on what tools researchers should have in their toolboxes. In part this is due to the onerous purchasing processes, which tend to have researchers cling to whatever tools they have in a sort of a conservative reflex—need to pound a nail? Use your shoe! In academia the situation is healthier, because generous educational discounts allow researchers to use whatever tools allow them to accomplish their job most efficiently by the deadline.

When I look out of my window at HP Labs in the Stanford Industrial Park, I can see other research labs, like Google Labs, IBM Almaden, Intel Research, Microsoft Research Silicon Valley, SRI, Sun Labs, Yahoo! Research, and others. When I walk around the terrace, I see more, like FXPAL, PARC, Ricoh Innovations, and so on…

» 2007 Japan Prize in technology

This year’s Japan Prize in technology, awarded for breakthrough basic research with a high industrial impact, goes to Albert Fert and Peter Grünberg, who independently described giant magnetoresistance (GMR), in which the electrical resistance of certain materials drops when a magnetic field is applied. GMR enables the high capacity found in today’s hard disk drives.
