Kodak High Sensitivity Image Sensor Tech

from News: Digital Photography Review (dpreview.com)

Kodak Image Sensor Solutions has today announced a new Color Filter Array (CFA) layout (and image processing path) as an alternative to the widely used Bayer pattern which should provide higher sensitivity. This new layout features one 'panchromatic pixel' (monochrome) to every colored pixel (red, green or blue) and there are three proposed layouts. Kodak ISS are presenting this as a technology solution which can be applied to any size, megapixel count or type (CCD / CMOS) of sensor. Kodak claim a one to two stop improvement in sensitivity, the tradeoff is of course color resolution which is effectively a quarter of the traditional Bayer pattern. This interesting development will of course only be proven when we see it actually implemented and we can compare it to traditional Bayer.

How To: Track your Flickr page views with Statr

from Lifehacker

Ever wondered how many people are perusing your Flickr photos? Statr is a web-based application that will track the amount of page views your Flickr account receives.

Statr for Flickr allows you to track and plot page views statistics for your Flickr account. Graphs are automatically updated on a daily basis and can be linked from external websites.

Getting started with Statr is a breeze -- all you need to do is grant Statr read access to your images. It takes Statr a day or so to collect data before it will begin displaying your page views. Unfortunately, Statr is a little simplistic and only displays page views. It doesn't give you any information about uniqueness of visitors, visitor frequency, visitor location, etc. If you're proud of your Flickr traffic, Statr also generates some in-line HTML so you can showoff your Flickr traffic graph.

Researchers use magnetic fields to manipulate light

from Engadget by Darren Murph

We've seen magnetics used in everything from closet improvements to insomnia treatments, but researchers at the University of Alberta and the United States Naval Research Laboratory have found that "by manipulating electron spin using magnetic fields, they can turn off and on light that's being guided through metals." By looking deeper into the fields of plasmonics and spintronics, the gurus have discovered that this on-off light switch could be used for tasks such as routing infrared light in optical communications or processing radio signals in cell phones. Additionally, this system could potentially decrease power requirements for the devices it invades, and while a finalized product isn't quite ready, the team is already anxious to "build devices that can act as switches in a chip."

River Glow project detects pollution with style

from Engadget by Donald Melanson

We've seen pigeons that monitor pollution and cement that eats pollution, but for eye-catchiness and do-goodedness, it's tough to beat Soo-in Yang and David Benjamin's River Glow project, which provides a light show as it keeps an eye on water quality. Built with a budget of $1,000, the current bathtub-bound prototype system consists of an LED connected to uncoated fiber optic strands, which gets triggered when the pH sensor detects changes in water quality. What's more, the whole thing's apparently powered by a single AA battery, which is recharged using floating strips of thin film photovoltaics. Presumably, that'd be scaled up before it gets let loose in some larger waterways (as seen above), although it's not clear when or if that'll happen. [Via Inhabitat]

from Engadget by Thomas Ricker

Samsung's gettin' busy this morning in Korea with the launch of their 70-inch Full HD LCD television. Not only is it the world's largest commercially available LCD, this 1080p pup also brings a 120Hz refresh along with Samsung's local dimming LED backlighting solution for a reported 500,000:1 dynamic contrast ratio... for whatever that measurement's worth. The LN70F91BD is another ACAP packer featuring 3x HDMI 1.3 terminals and a USB 2.0 jack for purposes unknown. Available in S.Korea only at the moment with worldwide sales starting in the second half of the year. Only ₩59,000,000 for the privilege which translates to about $63k or €48k -- chump-change for culturally ambiguous superstars. [Via AVING]

The 3D Real/Virtual World Hybrid: How Far Away?

from TechCrunch by Michael Arrington

How long will it be until we can stroll through the streets in a virtual world that is identical to our own? Given the state of a number of technologies, not very long. Over the last couple of years we’ve seen Microsoft Street Side and Virtual Earth as well as similar efforts from Google. But different technologies are now being deployed that are even more interesting that the results achieved from large companies taking and processing massive numbers of photos into now-standard 3D views.

Two standouts are Microsoft’s Photosynth Project and newcomer Everyscape, which Brady Forest wrote about today on O’Reilly Radar.

Sanyo LP-XL50 projector touts uber-short throw

from Engadget by Darren Murph

For those who picked up Sanyo's LP-XL40 wide-angle projector for its sensational short-range capabilities, we hope your wallet's prepared for an upgrade. The firm's newest LP-XL50 steps it way up by touting the ability to shoot an 80-inch image onto a screen with just 8-centimeters of space between the lens and the wall. Moreover, you can still squeeze out marginally smaller images from even closer ranges thanks to its newfangled optical engine. Specs wise, you'll find a 1,024 x 768 native resolution, 275-watt UHP1 lamp, 2,000 lumens, "blackboard mode" for mounting just above a classroom board, theft deterrent system to foul up those mischievous kids, a pair of VGA inputs, component, S-Video, and composite connectors, and a built-in two-watt speaker to boot. Unfortunately, it seems that you'll be waiting 'til late December to throw down your ¥600,000 ($4,931), but click on through for a few more looks for the time being.

GigaOM Top 10 Most Popular MMOs

from GigaOM by Blake Snow

WoW The attention surrounding MMOs (massively multiplayer online worlds) has never been greater. But it’s not just role playing games along for the ride; non-game, avatar-driven virtual communities are just as popular, if not by more, and we’re not just talking Second Life here.

So in an effort to cut through the hype and glean some context, here are the most popular MMOs in terms of active users or subscribers, based on publicly available data. These titles may or may not be games, but the medium has expanded far beyond Tolkienesque fantasy worlds. They all are Mac-friendly/Web-based with exception of Guild Wars.

1. World of Warcraft, released 2004 - 8.5 million subscribers. While Habbo is giving Blizzard a run, the numbers generally support WoW as the biggest MMO in the world. Important qualification, though: only 4 million are based in the West and monthly subscribers, while its 4 million Chinese players only pay roughly 4 cents an hour to play it in Internet cafes.

2. Habbo Hotel, released 2000 - 7.5 million active users. The Finland-based “social game” MMO popular with teens and growing fast. Look out, Horde!

3. RuneScape, released 2001 - 5 million active users. A Java-based MMORPG operated by Jagex Ltd. with over nine million active free accounts. Boasts one million paying customers. Fancy that.

4. Club Penguin, released 2006 - 4 million active users. MMO for the kiddies developed by New Horizon Interactive. The game shares similarities with other social environments like Habbo Hotel.

5. Webkinz, released 2005 - 3.8 million active users. Here’s a novel idea: create beanie baby like stuffed animals, assign them a unique ID, then create an MMO portal in which kids can spend even more time using your product. When kids graduate from Club Penguin, they go to Webkinz (or so I’m told.)

6. Gaia Online, released 2003 - 2 million active users. Not quite an MMO, not quite a social site, but founder Derek Liu has openly stated the networks desire to focus on social gaming. Forums make up 30% of the current site activity.

7. Guild Wars, released 2005 - 2 million active users. Another MMORPG made by the popular NCsoft out of South Korea. No Mac love here, but a lot of active users.

8. Puzzle Pirates, released 2003 - 1.5 million active users. Published by Ubisoft and developed by indy king Three Rings, Puzzle Pirates merges casual games with a rising interest in pirate culture. Puffy shirt aside, it’s working like a charm.

9. Lineage I/II, released 1998 - 1 million subscribers. Published by South Koreas NCsoft, Lineage was once the most popular MMO of its day. At one point total active users peaked at 3 million. A Western release in 2002 mostly fizzled.

10. Second Life, released 2003 - 500,000 active users. No introduction needed here. Created by Linden Labs, this virtual world features a rabid fan base, inflated numbers, a high influx of corporate doppelgangers, and lots of digital genitals. First life optional.

Other popular MMOs are sure to exist, particularly new-comers and non-localized Asian games that are sure to grow. Also, this list reflects popularity alone, not necessarily revenue models, though World of Warcraft is performing well on both counts.

For all intents and purposes, the most popular MMOs represent an estimated 50-75% of the total MMO market (30-60 million active users.) Is that enough attention to justify MMO’s recent surge of attention? Maybe not all of the hype, but definitely a large portion of it. And who wouldn’t want a piece of Blizzard’s reoccurring pie or another revenue model with a similar install base?

Interestingly, however, it’s apparent that no single business model is winning out. Subscriptions work well for MMORPG games like WoW that are more akin to crack cocaine than mere entertainment. But what about other non-game MMOs? How will companies bank on consumer attention in those areas? One thing’s for certain: with all the popularity surrounding MMOs several new business models are sure to flourish in the coming years, as it’s not just about games anymore.

*Of Western origin or with a localized presence here. “Active users” based on most recent monthly log-in figures when available. Subscriber numbers are not necessarily a reflection of active users. Figures compiled from Wikipedia (excluding, to the best of my knowledge, free trials, beta users, and web visitors without accounts.) Virtual Worlds News also referenced; Habbo figures taken from company spokeswoman, Second Life figures from most recent published stats. Special attention was given to notable MMOs in terms of where they stack up when looking at the numbers in addition to their popularity and/or high profile (i.e. Second Life.) Amendments and additions welcome.

Kodak color-filter technology could redefine low-light shooting

from Engadget by Darren Murph

We already knew that Kodak was up to something good when it began to phase out low-end digicams and refocus on developing new technologies, and now it seems like we've got one more innovation from its laboratory to look forward to. Reportedly, Kodak has developed a "color-filter technology that at least doubles the sensitivity to light of the image sensor in every digital camera." Bold words, we know, but even Chris McNiffe, general manager of the photography company's image sensor business, went so far as to say that this very invention would enable a "2x-4x improvement in light sensitivity." The company also suggested that a variety of camera manufacturers could expect samples of said technology during the first quarter of next year, and while consumer rollouts weren't detailed, we do know that this magical concoction will hit P&S cameras first with cameraphones to get equipped shortly thereafter.

projectiondesign's Action! M25 DLP projector does 1080p

from Engadget by Darren Murph

Sure, Epson and Philips' endeavor to create a mini projector may be novel, but projectiondesign's forthcoming device packs the power we AV freaks admire. Touting an almost unbelievable assortment of niceties, this 3.7- x 9.2- x 10.8-inch DLP machine is reportedly the "world's smallest" Full HD projector to date, and if that wasn't inspiring enough, it also uses TI's 0.95-inch 1080p DMD, the firm's proprietary RealColor technology, and plays nice with home automation systems with RS-232 and IP interfaces. Additionally, it sports a 10-bit video processing engine, HDMI 1.3 compatibility, 1,000 lumens, and a even-segment, 5x color wheel. Best of all, this HD-lovin' projector is available for purchase as we speak, but we're assuming that the unlisted price is a good sign that we common folk should just keep on looking.

Lawyers and the $54 million pants

America is a "sue-happy" country. Where else can you sue the dry cleaners for $54 million because they lost your Hickey Freeman pants. You think I am joking; but this is a case of life being stranger than fiction. A Washington DC judge (who in my opinion should know better) is suing a dry cleaners that lost his pair of pants.

For a moment last week my trust in the American legal system began to fail as Paris Hilton, heiress of Hilton Hotels (NYSE: HLT) fortune, spent a heart-wrenching three days in jail before being released by the sheriff for "medical reasons." Then suddenly my faith was restored as the judge sent her back to jail.

Well it didn't last long. It seems this week a pair of lost pants is worth crying over -- and $54 million. I guess America is land of the free and home of too many lawyers. Maybe this is why I respect Vice President Cheney: I mean, we all talk about the problem with lawyers, but at least he shot one.

The Long Tail in real life

Wow, talk about a visualization of Chris Anderson's "The Long Tail" in action! This graph indeed shows how the tail has lengthened and that music discovery sites like this one (iLike.com) are helping potential consumers of such content reach further into the tail to discover stuff that they like and to then be able to buy the song one at a time.

Wis.dm Takes a Simple Look at Q&A

from TechCrunch by Nick Gonzalez

Toward the end of last year we covered a veritable cornucopia of question and answer sites. They mostly served as aggregation sites for members to post, answer, and rate questions. Yahoo effectively dominated the space, leveraging their user base and even adding an API. Q&A service Wis.dm has taken a different look at questions and answers, and added a Facebook application today.

Wis.dm is for simple yes/no questions, not about writing long answers to life’s most elusive questions. Within the Facebook application you can answer a stream of questions that appear on Wis.dm. Unfortunately you can’t ask questions through the application right now. As you answer questions, Wis.dm assigns you points and matches you with other users that answer questions similarly to you.

The long-term vision is to match up potential friends and help silo Wis.dm users into interest groups. Matching people based on their answer history is also gives them a clear way to insert contextual advertising into the question stream. Advertisers on Wis.dm will be able to target their ads based on a user’s question profile (i.e people who answer positively to sports questions, get the latest ESPN ad).

Toshiba announces new "3D" NAND flash technology

from Engadget by Donald Melanson

It looks like Samsung's not the only one trying to build a better NAND flash chip, with Toshiba now joining the fray today with news that it's made some advancements of its own. Much like Samsung, Toshiba's apparently managed to cram more storage into roughly the same size chips by changing the way the various elements are stacked, in this case busting things out into three dimensions. According to Toshiba, the so-called "pillars" of stacked memory elements can be squeezed into a tighter space thanks in part to some shared peripheral circuits, although that apparently comes at the expense of a longer and more complex manufacturing process. What's not clear, however, is exactly how big an increase that'll translate to in terms of bits and bytes, nor is there any indication as to when we might actually see some NAND units based on the technology.

Chime.TV: A Prettier Way to Watch YouTube

from TechCrunch by Nick Gonzalez

Chime.Tv’s video player has got the kind of flash and style Ruby developers would envy, especially since it’s programmed in PHP and AJAX. The player, which dishes out 22 themed channels of viral video content, with a bunch of added utilities.

The full page player is similar to Joost and Babelgum, but in your browser. Like the IPTV guys, you can flip through pre-made channels, roll your own, or search for content by keyword. The player is pretty hands off, and will just run if you give it a channel or a search term to munch on. The player searches through videos on YouTube, Veoh, Metacafe, Google Video, and DailyMotion. You can reorganize the results by title, length, or randomize. They also have a bookmarklet so you can add content to your channels as you surf the web.

So, iIf you want to create the “bikini” channel, all you have to do is search for “bikini” in the search bar and Chime will start playing through all the results. The player also has a friend feature for sharing your channels and vids with someone else.

The player can play in full screen mode, wide screen, or anywhere in between by dragging the corner of the video. It also comes with some color controls for brightness, contrast, and color in case the original quality is less than stellar.

All this thing needs is a mashup with one of the TV show aggregators.
