HP Envy 4 shows up for pre-order on HP's China site, priced as low as 5,499 yuan
A few days ago, HP accidentally listed the unannounced Envy 4 and 6 on a support page within its American website. Fast forward to today, and the company's Chinese site is following in similar footsteps -- though, this time around exposing a couple more details. HP's online shop in China shows a total of six different Envy 4 models, starting with the 1005tx / 1019tx, followed by the mid-level 1004tx / 1021tx and ending with what appears to be the higher-end Ultrabooks: Envy 4-1006tx and 1021tx, which are both priced at 6,299 yuan (around $1,000). As expected, the pair sitting at the bottom of the pile is the lesser-specced of the bunch, revealing an Intel Core i3-2367M CPU, while the top-shelf machine (1021tx) is listed as sporting a Core i5-2467M. Taking into consideration all the recent leaks, it's now only a matter of time before Meg Whitman & Co. make these 14-inch skinny laptops an "official" reality. Until then, those living in China can try and pre-order one of these by pointing your browser toward the source link below.

Egypt?s shaky finances: Can the IMF and government agree on a loan deal?
The IMF wants assurances that the political leaders who emerge to run Egypt after elections next month will be on board with the financial requirements underpinning a proposed $3.2 billion loan.
The International Monetary Fund is moving closer to approving a multibillion-dollar loan to help Egypt shore up its shaky finances, but the failure of some emerging political players in the Arab Spring country to endorse the plan is holding up a final agreement.
Skip to next paragraphEgyptians vote next month in the first presidential election since the fall of Hosni Mubarak last year. And the IMF wants assurances that the political leaders who emerge to run the country will be on board with the financial requirements underpinning a proposed $3.2 billion loan.
On the other hand, some Egyptians and international financial experts are asking if it is even appropriate for a lame-duck military government to complete a deal that ties the hands of a future government.
The issue of Egypt and, more broadly, the Arab Spring countries, will be a chief concern of the spring meetings of the IMF and World Bank this weekend in Washington. The question is: How does the global financial community follow through on its commitment to help them on the road of reform?
In December, IMF Managing Director Christine Lagarde said her institution had set aside $35 billion for loans to help shore up the Arab countries in transition. But since then, concerns about commitments to reform and questions about leaders? ability to hold up their end of a deal have held up agreements.
As Ms. Lagarde said at a Washington press conference Thursday, the IMF ?stands ready [and] will help each of those [Arab Spring] countries,? but she said the countries would also have to adhere to the IMF?s rules to get the loans.
?With IMF programs, it takes two to tango, right?? she said.
In the case of Egypt, the wise thing might seem to be to wait for the new government to emerge, given the doubts about future support for a loan. But the problem is that Egypt?s finances and economy are deteriorating now, and fast: The country?s foreign reserves have shrunk by more than half, tourism has plummeted, unemployment has jumped ? and as a result, Egypt needs an infusion of as much as $12 billion from public and private sources to stabilize its finances, experts say.
The IMF has two basic conditions for extending loans Lagarde says: First, the IMF must have negotiated with authorities an economic plan that will ?actually help that country pull itself out of the difficulty it is in?; and second, there must be ?broad political support in the country? for the loan program.
Until recently, the Muslim Brotherhood?s Freedom and Justice Party, which emerged as a dominant political force in parliamentary elections several months ago, opposed any IMF package, but party leaders appear to have switched to favoring the loan. That endorsement has helped fuel renewed optimism among IMF officials that a loan the organization had hoped to agree on with Egypt in March can still be concluded this month.
On Friday, Masood Ahmed, IMF Middle East director, said prospects for a deal with Egypt were brightening. ?We feel there is some progress in terms of getting a commitment and broad buy-in to the objectives and the measures? of a loan program, he said.
Concluding a loan with Egypt would be a good signal to the region, he added, which he said continues to experience a slowdown in economic growth as a result of the repercussions of political upheaval and the effects of Europe?s debt crisis.

With 7B Photos, Flickr Debuts New Speedy, HTML5 Image Uploader; Drag And Drop Interface, And More
Yahoo's photos sharing site, Flickr, has been steadily redesigning a number of components of its platform over the past few months, including editing (courtesy of Aviary), photo views and more. And today, Flickr, which says it is home to more than 7 billion photos, is debuting a new, speedier, HTML5 photo uploader for images. With the HTML5 technology, Flickr's uploader has a more robust experience, including drag and drop functionality. So instead of only being able to upload manually, you can add photos by dragging them into the browser. Yahoo will also show your thumbnail previews of photos, so you can manage and reorder photos before they hit your photostream. And you can zoom, rotate or sort your photos by title within the uploader itself, as opposed to within the photostream.passover recipes 2012 kids choice awards kansas ohio state wrestlemania results womens final four josh hutcherson google april fools
The Lighter Side of IT Consumerization
You've probably heard the term "consumerization of IT." Some of the network and security pros reading this probably think this is yet another meaningless industry buzzword with little or no value. However, to dismiss it as such is to potentially miss out on what is both a very powerful concept ... and one that information security practitioners ignore at their peril.

Computing the best high-resolution 3-D tissue images
ScienceDaily (Apr. 23, 2012) ? Real-time, 3-D microscopic tissue imaging could be a revolution for medical fields such as cancer diagnosis, minimally invasive surgery and ophthalmology. University of Illinois researchers have developed a technique to computationally correct for aberrations in optical tomography, bringing the future of medical imaging into focus.
The computational technique could provide faster, less expensive and higher resolution tissue imaging to a broader population of users. The group describes its technique this week in the online early edition of the Proceedings of the National Academy of Sciences.
"Computational techniques allow you to go beyond what the optical system can do alone, to ultimately get the best quality images and three-dimensional datasets," said Steven Adie, a postdoctoral researcher at the Beckman Institute for Advanced Science and Technology at the U. of I. "This would be very useful for real-time imaging applications such as image-guided surgery."
Aberrations, such as astigmatism or distortion, plague high-resolution imaging. They make objects that should look like fine points appear to be blobs or streaks. The higher the resolution, the worse the problem becomes. It's especially tricky in tissue imaging, when precision is vital to a correct diagnosis.
Adaptive optics can correct aberrations in imaging. It's widely used in astronomy to correct for distortion as starlight filters through the atmosphere. A complex system of mirrors smooth out the scattered light before it enters the lens. Medical scientists have begun applying adaptive optics hardware to microscopes, hoping to improve cell and tissue imaging.
"It's the same challenge, but instead of imaging through the atmosphere, we're imaging through tissue, and instead of imaging a star, we're imaging a cell," said Stephen Boppart, a professor of electrical and computer engineering, of bioengineering and of internal medicine at the U. of I. "But a lot of the optical problems are the same."
Unfortunately, hardware-based adaptive optics are complicated, tedious to align and extremely expensive. They can only focus on one focal plane at a time, so for tomography -- 3-D models constructed from sectional images as in a CT scan, for example -- the mirrors have to be adjusted and a new image scanned for each focal plane. In addition, complex corrective systems are impractical for handheld or portable devices, such as surgical probes or retinal scanners.
Therefore, instead of using hardware to correct a light profile before it enters the lens, the Illinois team uses computer software to find and correct aberrations after the image is taken. Boppart's group teamed up with with Scott Carney, a professor of electrical and computer engineering and the head of the Optical Science Group at the Beckman Institute, to develop the technique, called computational adaptive optics. They demonstrated the technique in gel-based phantoms laced with microparticles as well as in rat lung tissue. They scan a tissue sample with an interferometric microscope, which is an optical imaging device using two beams of light. The computer collects all of the data and then corrects the images at all depths within the volume. Blurry streaks become sharp points, features emerge from noise, and users can change parameters with the click of a mouse.
"Being able to correct aberrations of the entire volume helps us to get a high-resolution image anywhere in that volume," said Adie. "Now you can see tissue structures that previously were not very clear at all."
Computed adaptive optics can be applied to any type of interferometric imaging, such as optical coherence tomography, and the computations can be performed on an ordinary desktop computer, making it accessible for many hospitals and clinics.
Next, the researchers are working to refine the algorithms and explore applications. They are combining their computational adaptive optics with graphics processors, looking forward to real-time in-vivo applications for surgery, minimally invasive biopsy and more.
For example, computational adaptive optics could be very useful for ophthalmologists. Boppart's group previously has developed various handheld optical tomography devices for imaging inside the eye, particularly retinal scanning. Aberrations are very common in the human eye, making it difficult to acquire clear images. But adaptive optics hardware is too expensive or too complicated for most practicing ophthalmologists. With a computational solution, many more ophthalmologists could more effectively examine and treat their patients.
"The effectiveness is striking," Boppart said. "Because of the aberrations of the human eye, when you look at the retina without adaptive optics you just see variations of light and dark areas that represent the rods and cones. But when you use adaptive optics, you see the rods and cones as distinct objects."
In addition, the ability to correct data post-acquisition allows the researchers to develop microscope systems that maximize light collection instead of worrying about minimizing aberrations. This could lead to better data for better image rendering.
"We are working to compute the best image possible," said Boppart, who also is affiliated with the Institute for Genomic Biology at the U. of I.
