Image Editing: Resize Images without Sacrificing Content with GIMP or Rsizr

from Lifehacker by Adam Pash

Popout Ever have to crop or resize a picture to fit it better on a web site but end up disappointed with the content you have to lose from the photo? Using a method called liquid rescaling, your pics can be rescaled while retaining almost all of the pertinent content, so you can get the best of both worlds—a smaller image that retains everything you want. If it still sounds a little unclear, check out the video to see this brilliant idea in action.

If you're a fan of the open source image editor GIMP, you can download and install the Liquid Rescale GIMP plug-in to get liquid rescaling results (after you install it by moving the downloaded files into your GIMP directory, you'll see the Liquid Rescale option under the Layer menu). If you don't feel like installing anything, you should try out the Rsizr webapp, which does the rescaling from the comfort of your browser. Both tools are a good deal slower than what you see in the very cool video above, and neither are implemented to the full extent of what you're seeing in the video, but the results are still promising.

Clocks: CB2's World Panel Clock is Sci-Fi Sexy

from Gizmodo by Haroon Malik

Our desks are so cluttered we have given up the fight for organization, and that is exactly why we are tempted by CB2's World Panel Clock. The transparent LCD display looks Star Trek awesome and has all sorts of useless information we would otherwise have on our desktops, including time and calendar functions.

As you well know, we are suckers for cool, as you can tell from our fantastic fashion sense...well, CB2's World Panel Clock certainly does have ample flair, with a brushed aluminum base and a slanted transparent display. The timepiece is battery powered, which will saves you adding to your wired disorganization and is available for a reasonable $24.95. The fight against unneeded, largely pointless gizmos is futile—we'll have one over here, please. [Product Page via Technabob]

Mansion: Jelly-fish 45 Habitat Won't Sting Your Pocket Too Much

from Gizmodo by Haroon Malik

If you have fallen a little short of the $50 million price tag for a Poseidon 180, fret not, the Jelly-fish 45 Habitat will set you back only a mere $2.5 million. Bargain! Designed by Giancarlo Zema, the "floating dwelling" comprises five separate levels all connected by a snazzy spiral staircase.

The floors are split into cheesy zone-titled areas including study, night, day, guest and viewing quarters. Though, if you purchase the floating mansion, you may abide by whichever nomenclature you wish. The viewpoint stretches 3m below the surface and looks jellyfish-like fantastic. The colossal seat-in-the-sea stands 10m high and 15m wide. Now, if I manage to roll out one hundred posts in 24 hours, Blam promises me a tour of his Jelly-fish 45 Habitat—game on!

Speechless: AT&T Lets You Talk, But Limits What You Say

from Gizmodo by Mark Wilson

AT&T has revised their Terms of Service in a manner that should horrify the consumer public. Usually such updates screw the customer subtly, but AT&T's new adjustment ironically pulls freedom of speech directly from those using AT&T's service to speak. In short, if you slam AT&T, they can pull your service:

AT&T may immediately terminate or suspend all or a portion of your Service, any Member ID, electronic mail address, IP address, Universal Resource Locator or domain name used by you, without notice, for conduct that AT&T believes...(c) tends to damage the name or reputation of AT&T, or its parents, affiliates and subsidiaries.

Of course, AT&T has overlooked one important fact about their TOS: they can't cancel a customer's service who will no longer do business with them anyway. Changes in TOS are often a loophole out of your contract. And if I were an AT&T customer, my choice would be pretty clear. [TOS via morningpaper]

Intel fleshes out 45nm Yorkfield launch details

from Engadget by Donald Melanson

It's been quite a while since we've heard anything from Intel on the Yorkfield front, but that looks to have changed in a hurry, with the company now busting out a whole slew of specifics on the forthcoming processors. First up is news that Intel will be releasing an "Extreme Edition" of the 45nm quad-core processor on November 12th, well ahead of the January 2008 launch for its decidedly less-extreme counterparts. Helping the processor (dubbed the QX9650) earn that designation is its top of the crop 3.0GHz clock speed, along with 12MB of L2 cache, and an extremely hot 130W TDP rating, not to mention a price just shy of $1,000. If that's all a bit too extreme for you, you'll also be able to get your choice of 2.5GHz, 2.66GHz, or 2.88GHz models, each of which scale the TDP rating down to a more manageable 95W, with prices running $266, $316, and $530, respectively. Even further on down the line, Intel's announced details on three dual-core Wolfdale desktop processors, which clock in at 2.66GHz, 3.0GHz, and 3.16GHz. No word on a price for the low-end model just yet, but the 3.0GHz and 3.16GHz are apparently set to run $183 and $266, respectively, with a mid-range 2.83 GHz version expected to eventually round out the lot, according to DailyTech. As if that wasn't enough, Intel's will also apparently be slippig out a 65nm 2.4 GHz dual-core Conroe processor dubbed the E4600 on October 21st, although there's no word on what it'll cost.

iPhone 1.1.1 "bug" unleashes music over Bluetooth

from Engadget by Paul Miller

The iPhone 1.1.1 update has a hidden little surprise for y'all: Bluetooth audio streaming is now available off of your iPhone for whatever you darn please, meaning you can finally listen to music from the phone wirelessly. Oddly enough, this "function" has been unleashed by a Visual Voicemail bug that leaves Bluetooth audio on even after you've left the Voicemail interface. Of course, it's only mono audio, and the audio keeps playing out of your built-in speaker -- if you plug in headphones to cut off the speaker you'll lose Bluetooth streaming as well -- but it's nice to see Apple forking over some "should have been there in the first place" functionality accidentally to go along with all that stuff of the same ilk 1.1.1 took away from us.

In the Lab: Beetle Juice

from Earth2Tech by Georgia Flight

We know you're busy, so we'll forgive you for overlooking this week's announcement that researchers at England's University of Leeds have discovered a way to mimic the toxic defensive spray of the bombardier beetle. But you'll want to sit up and pay attention when you find out why: to create a new water-based compression technology called µMist that's being touted as the key to everything from improved fuel efficiency to next generation fire suppression to chemical-free drug delivery.

The lead researcher, Professor Andy McIntosh, describes the beetle's abilities as a type of complex pressure cooker. "Essentially it's a high-force steam cavitation explosion," he says in the release , "Using a chamber less than one millimeter long, this amazing creature has the ability to change the rapidity of what comes out, its direction and its consistency."

The µMist spray technology represents a huge potential leap forward for the precision control of droplet size, velocity and consistency, which in turn could have a massive impact on the efficiency of any system that uses mist as a delivery system–namely fire suppression, medical drug delivery and of course, fuel injection. The team has built a 2-cm chamber that can deliver mists up to 13 feet away, or produce a mist as fine as two microns. Hmm, imagine a fire extinguisher that fits in your pocket…

Say it with us now: Beetle juice, beetle juice, beetle juice. Biotech startup Swedish Biomimetics 3000, a self-described "V2PIO" (that's virtual venture philanthropic intersectional organization), found the research so promising that the company has inked a worldwide exclusive development and marketing deal for the µMist technology. No word yet on when these beetles will make their U.S. invasion.

Jajah Now Does Click To Call For Anyone

from TechCrunch by Nick Gonzalez

Jajah will be officially announcing their click-to-call buttons on Monday. The buttons, which let people call the owner for free and anonymously, have been quietly in private beta over the past year. They are also taking on international calling card services and Jaxtr and Jangl, who already have click-to-call offerings on social networks and dating sites.

The call buttons are available to registered Jajah users and come as a bit of embed code you can put on your web page or at the end of an email. They come with several customizations. You can adjust the CSS styling, adjust the number it calls, and restrict which countries can try to call you.

When users click the button, the caller enters their phone number and Jajah connects the two parties over a VOIP line. The callee is then told who called and asked if they want to accept the call, say they're busy, or blacklist the number. If they accept the call, the minutes are charged to their Jajah account, like an "800 number". At two to three cents per minute, it can be used for some cheap long distance calling. For the cost conscious, Jaxtr and Jangl are still free, however.

Fusion-io's ioDrive puts power of a SAN on a PCIe card

from Engadget by Darren Murph

In a recent demonstration at DEMOFall '07, Fusion-io showed off its newest PCIe device, which reportedly "places the power of a SAN (storage area network) in the palm of your hand." Essentially, this single device boasts up to 640GB of storage capacity, delivers 100,000 IOPS (input / output per second) and can achieve sustained data rates of 800Mb/sec (read) and 600Mb/sec (write)." In marketing terms, the ioDrive can perform "nearly a thousand times faster than any existing disk drive," and it can reportedly be integrated into existing data centers or workstations without any alterations to your infrastructure. Next quarter, the outfit will begin shipping the card in 40GB, 80GB, 160GB and 320GB configurations (with the 640GB flavor to follow suit), but unfortunately, official prices have not yet been divulged. Oh, and be sure to check out a video of the ioDrive's unveiling here. [Via TGDaily]

MAGNETIC REFRIGERATOR NEEDS NO ELECTRICITY

Scientists at the Technical University of Denmark have created a refrigerator that cools using magnets instead of electricity

A group of researchers at the Technical University of Denmark's project laboratory in Risø have discovered a cooling method that uses magnetic materials instead of electricity, reported daily free newspaper Nyhedsavisen.

The invention will allow for refrigerators to replace existing electric refrigerators in homes and businesses with a fully environmentally friendly power source. Although the first prototype will not be ready until 2010, the project's researchers say the appliance's cooling cycle efficiency will be 60 percent greater than that of conventional refrigerators.

The new method uses opposing magnetic fields to increase the temperature of the materials employed. The heat energy is transported through a non-volatile fluid, such as water, and then thermodynamically reversed to a cold temperature. The scientists have already been able to cool a 20° C room to 11°C using the new technology.

'It probably isn't realistic to believe that magnetic cooling technology will be immediately available for consumer use, especially as refrigerator manufacturers have brought prices down so much in the past few years,' said Christian Bahl, one of DTU's project researchers.

But Bahl said another of the magnetic refrigerator's advantages is that it is silent.

'So it will likely be first used in various niche areas, such as places where a quiet environment is an important factor.'

Although magnetic cooling is not in itself a new research field, the DTU scientists were the first to use the technology in an actual physical setting to cool room temperatures.

Out-of-Context Ads Prove Effective

Augustine: it's not that the "out-of-context" ads are effective; it's more like it is no less effective than ads placed in-context because both kinds are ineffective. When users want to find something, they will look for it. Any other time, they will ignore it. So no matter where the ad is placed, dismally low click rates will still be observed.

Yahoo! and MediaVest studied a group of consumers passionate about a particular subject area. Out-of-context ads proved about as effective as in-context placements.

NEW YORK New research casts doubt on the long-held belief that advertising is most effective when placed near content related to the product.

Yahoo! and MediaVest recently studied a group of consumers passionate about a particular subject area. Product ads displayed out of context had roughly the same impact on brand preference as identical placements shown next to related content.

Yahoo! asked self-identified food lovers to rate various brands, including the single-serve gourmet coffee product Tassimo. Brand affinity increased 26 percent among those shown the ad on a Yahoo! Food page, and 21 percent among those shown the same ad on a Yahoo! News page.

While the finding was a small part of a wide-ranging study, it suggests some softness in the long-held belief that ads shown in context are more valuable than those seen out of context.

This becomes a key issue moving forward: With new targeting tools, it is easier than ever to find specific audiences, such as foodies, wherever they are online, rather than only on food-related sites.

"Targeting the right people is more important than the content," said Jim Kite, president of connections research and analytics at MediaVest, part of Publicis Groupe.

The study supports earlier research by behavioral targeting companies like Tacoda and Blue Lithium. A Tacoda study in late 2005 found that users actually noticed out-of-context placements based on behaviors more than in-context placements. And according to an Oct. 2006 study by Blue Lithium, out-of-context, behaviorally targeted ads yielded higher conversion rates, though fewer clicks.

The findings should lift the spirits of companies like Yahoo! and AOL that are busily reinventing themselves, relying on their ad networks to give them added reach. Yahoo! has inked a deal to buy Blue Lithium; Tacoda is now part of AOL. With their portal sites serving as gateways, both companies hope to use their network assets to target ads to people with specific interests once they leave the portals for other online destinations.

For the most part, in-context ad placements are priced higher than those shown out-of-context with targeting information.

The study is notable because it gauged the most valuable customers: those passionate enough about subjects to spread messages—including brand messages—among their peers.

The study estimates that, depending on the category, 17-31 percent fall into the hyper-engaged consumer category dubbed, "Passionistas." Fifty-two percent are more likely than average consumers to recommend a product. It's no surprise that ads imparting some knowledge and/or added value on subjects of interest were found to have the greatest appeal.

"If a brand aligns with a passion, it doesn't matter where the audience is," said Edwin Wong, director of consumer insights at Yahoo!.

Useful Modding: Scientists Hack CD Player, Transform It into Lab Scanner

from Gizmodo by Addy Dugdale

When researchers at the Universidad Politécnica de Valencia needed a lab scanner, but didn't have the cash to pay for it, they didn't panic. Instead, Angel Maqueira and his colleagues bought a bog-standard CD player &mdash and hacked it, saving themselves a potential $70,000 in the process.

By soldering two additional light sensors inside the CD player, and then using software, the researchers were able to control how the device "played" a disk. The substance to be analyzed (in this case, the team was trying to detect traces of three different pesticides in various samples) was then placed on a normal compact disc, and inserted into the machine.

While the first light sensor identified where the sample was on the disc, using black marks on the edge of the disc, the second analyzed the sample itself, measuring the amount of laser light that was able to pass through the disk. Normally, discs reflect around 30 percent of the laser beam onto the reading head, while the rest passes through.

The sample, half a millimeter in size, was treated to produce dye or silver that was inversely proportional to the amount of pesticide in the sample. Using the modded CD player, they could detect pesticide levels as low as 0.02 micrograms per liter just by seeing how much laser light passed through the disc to the second sensor.

While it may not be as accurate as genuine lab sensors, which can cost between $42,000 and $85,000, the hacked CD player is accurate enough for many laboratory tasks &mdash some experts think the cheap and cheerful device would work wonders in developing countries, helping the fight against malaria, for instance. And the shorter wavelength lasers of Blu-ray and HD DVD technology will make the process even easier. [New Scientist]

Pure Digital announces million camcorder giveaway for non-profits

from Engadget by Donald Melanson

At under $200, Pure Digital's recently announced Flip Video camcorders are already pretty inexpensive, but the company now looks to be trying to make them even cheaper for non-profit organizations -- as in free. That's the goal of the company's just announced Flip Video Spotlight program, which aims to give up to one million of the camcorders to non-profits and other non-governmental organizations over the next five years. Apparently, the initiative (which is set to get underway this December) will operate as a donor matching program, with donors (or the organizations themselves) able to purchase so-called Flip Video Spotlight Kits, which Flip Video will match one-to-one. Much like the OLPC program, Flip Video sees virtually no end to the benefits of its camcorders, with Pure Digital CEO Jonathan Kaplan saying the company believes "video can help change the world."
