Geek deals: $180 discount Dell XPS 12 convertible, 50-inch plasma

When it comes to laptops, there is one major thing that catches my eyes: the screen. Not only do I have a preference towards high resolution (as we’ve covered many a time in these deals), but the quality of the screen is paramount as well.

When you can get an ultraportable laptop with a top notch screen and great performance, it is nearly an event worth celebrating. When the same machine is available in an innovative, convertible chassis, that’s pretty sweet. Toss in some rare discounts and we’ve got the makings of a hot deal.

 

Dell’s XPS 12 is definitely one of the more unique laptops available today. The 12.5-inch display serves up an impressive 1920×1080 pixels and does it on an IPS multi-touch LCD panel. Not only is it super crisp and gorgeous high resolution, but the wide viewing angles, rich colors, and of course touch capability combine to make for one killer screen.

Then consider the XPS 12′s unique chassis: the screen rotates within the display frame itself, allowing you to use it as either a traditional laptop or slate tablet. We’ve seen similar tricks before on other tablets, but none that achieved it quite like this and the reviews look good.

Right now you can get a bonus $80 coupon on any of the XPS 12 models. Combining this with $100 instant savings on the base model with Core i5, 4GB of RAM, and 128GB SSD nets you the lowest-ever price on an XPS 12 — $1019.99.

If you can front a little more coin, you can snag an upgraded model with 8GB RAM and 256GB SSD for $1419.99 after coupon, plus a $300 Dell e-gift card. This gift card is good for anything sold by Dell.com, so presuming you want to snag some new electronics anyway, this results in a net out of pocket cost of just $1119.99 for a well spec’d premium machine.

Thinner MacBook Pro using a Haswell processor expected at WWDC

On June 10 Apple kicks off its 4-day Worldwide Developers Conference in San Francisco, better known as WWDC. Last year’s conference saw a new MacBook Pro unveiled complete with a Retina Display and a resolution of 2560 x 1600. And this year the focus is yet again expected to be on the MacBook Pro and Apple’s thinner and lighter laptop the MacBook Air.
Of course, Apple isn’t saying anything until WWDC begins, but that doesn’t stop analysts taking educated guesses as to what we can expect to see. This year, Intel’s Haswell processors are expected to allow Apple to make a few changes to their laptop line up. More specifically, it’s expected the Pro models will get even thinner.

Currently, both the MacBook Pro and Air use Intel’s Ivy Bridge processors. Haswell improves upon Ivy Bridge in a number of ways, but most significantly for Apple, reduces power consumption and adds an advanced power saving system. That means less heat production and the same battery life from a smaller battery.

If Apple embraces Haswell early, which it is expected to do, we could see a new MacBook Pro unveiled that’s even thinner than the current 0.95-inch 2012 version. Alternatively, we could see the thickness stay the same, but the battery life extended beyond the existing 7 hours Apple quotes.

KGI securities analyst Ming-Chi Kuo believes Apple will opt for a thinner MacBook Pro. The FaceTime HD camera is also expected to improve from the existing 720p part to a 1080p-capable solution. As for the MacBook Air, alongside a similar move to Haswell processors, it’s also expected that dual built-in microphones will be added for improved voice quality.

Such improvements are just speculation, but I’m sure many would argue the MacBook Pro is already thin enough and improved battery life is more desirable. Apple shipping a new Pro that looks the same as the existing model, but achieves 10 hours of battery life surely wouldn’t lose it any fans. A similar battery life improvement for the MacBook Air would also no doubt be welcomed.

Asus Brings Intel Haswell Processors To Laptops & Desktops

Intel recently announced their 4th-Generation Core Processor codenamed Haswell and PC makers are already making news about including them in their upcoming systems. Among them Asus has announced their next desktops and all-in-ones which would be housing the Haswell chips right before Computex trade show, which is to be held at Taipei. The other companies include Cyberpower and MicroCenter. At Computex, other PC makers are expected to display their new PCs including the major manufacturers like Dell, Acer and others.

The Haswell chips add about 10 to 15 percent increase in their performance compared to the previous 3rd-Generation Core Processors codenamed Ivy Bridge. These chips are said to have lesser power consumption and lower heat generation and a considerable increase in the efficiency in battery life in laptops also.

Intel has announced only 4th-Generation Core i5 and i7 processors, with several others to be announced later at Computex. Among the two, the latter is the most powerful. Gaming desktops with Haswell processors, along with graphic cards would be able to handle any high demanding games out there. The Haswell has better speed and power efficiency over the previous Ivy Bridge processors which is equal to the same jump it had from the Sandy Bridge processors. With Haswell, consumers could have a mean desktop computer in their homes.

Haswell processors are expected to be rolled into the upcoming desktops and laptops soon, and will eventually make their way into ultrabooks. It didn't take long for the 4th-Generation Processors to be released after the previous Ivy Bridge Processors which came out just last year. Intel has always dominated the desktop and laptop processor market with AMD fighting with their processors and APUs. With the fabrication of these processors going down and the efficiency going sky high, a lot is expected for the future architecture of processors fron Intel. People might have always thought why Intel hasn't entered the mobile processor domain where Samsung and Qualcomm are leading the race, but who knows, Intel may have something up its sleeve, hidden from us.

Yahoo Chucks 'Classic Mail', New Upgrade Mandatory

From today, June 3rd, Yahoo will get rid of its "Classic" Mail once and for all. In fact, beginning this week Yahoo! Mail will no longer support older versions. It's either the new, upgraded version of Yahoo Mail or no Yahoo Mail at all. The company has sent out emails informing its users of the same and has notified them of the pending upgrade. Until now, Yahoo had allowed its users to continue using the old versions of the Mail even though the webmail interface was redesigned sometime around last year. But, it seems that this upgrade is more concerned with the refurbishing of the company's goals than the technical up-to-dateness. With the proposed upgrade comes the prerequisite of accepting the Communications Terms of Service and Privacy Policy. This grants Yahoo the permission to scan and analyze your incoming and outgoing mails, quite like Gmail does. This automated content scanning is purposed to deliver product features, relevant advertising, and abuse protection to the customers. If you're not interested in contextual-based advertising, you could change the settings using the Ad Interest Manager.

Now, if for some reason, you absolutely do not wish to upgrade, you are left with two options. The first option is to download your Yahoo Mail using IMAP, which will allow you to access your email from a different email program, such as Outlook, Mac Mail, or your mobile app. This, however, does not count as an exception and you'll still have to accept the Communications Terms of Service. If you don't want to do that, then as you might have guessed it, the only option is to close your account and leave. What would you choose?

Cisco Predicts Major Global Internet Traffic Surge by 2017

At its seventh annual Visual Networking Index, Cisco suggested the possibility of a drastic increase in the global internet traffic. According to the company, a growth rate of 23 percent is expected between 2012 to 2017. This dramatic burst isn't supposed to last but will be enough to aggregate to 1.4 zettabytes (ZBs) of global traffic by 2017. That amount alone is greater than the history of internet from 1984 to 2012 (1.2 ZB). Cisco predicts that by the year 2018, almost half of the world's population will be online. The surge in online activity could be attributed to more users, users connecting more devices, growing network and broadband speeds and more media-rich content in the next few years. With that many users, comes the need of sustainability. The average internet speed is expected to go up too. Mobile connections will target 8Mbps by 2017 and Wi-Fi speeds are anticipated to reach 30Mbps.

Technological advances will broaden the aspects of connectivity with more and more devices connected to the Internet. Cisco also forecasts a potential rise of M2M (Machine to Machine) products. It highlights the increasing interaction of quotidian devices with the real-world. For example, a refrigerator that can talk to people or is able to interact with other machines. 2017 is likely to see a total of 8 billion devices connected as M2M, combined with the support of IPv6-capable devices.

3D Printing In Space @ Zero Gravity In ISS

3D printing experiment is being done in the space under zero gravity conditions at the ISS. If the experiment is successful, we'll soon see a new era of manufacturing parts in the space. 3D print will use extrusion additive manufacturing that builds objects layer by later from polymers and other materials. NASA and a California based firm 'Mad In Space' have joined hands to begin the experiment in the next year. It'd be the first 3D microgravity experiment to be carried out in the International Space Station.

One of the aims of the experiment will be to test the technology to reduce cargo weight and volume. In future, the astronauts will be able to print the tools or components they need while in space. NASA believes in the potential of 3D printing technology and believes that one day, it will allow humans to manufacture entire spaceship in the space. This would eliminate the design constraints caused by the launch-related restrictions.

The importance of 3D printing technology is growing every day. NASA believes that this technology will be incredibly useful in our mission to send humans to Mars.

Acer Liquid S1 Phablet - The 5.7" Jelly Bean At €349 In Asia & Europe

Alongside the Acer Iconia W3 Tablet, the Taipei based Taiwanese manufacturer has also launched a first-of-its-kind phablet called the 'Acer Liquid S1'. Designed to be your companion in travel, the huge 5.7" HD (1280 x 720 pixel resolution) screen is supposed to help you increase your productivity levels on-the-go. A 'mobile wireless office' is how Acer describes its self-proclaimed phablet. And if or not rightfully so, this smartphone-tablet combo has support for dual SIM cards and is running over the latest Android 4.2 Jelly Bean. Powered by a quad-core 1.5 GHz processor, Acer thinks, and we try to believe, that the phablet's battery sustains a day full of usage.

The company has tried to fit-in a lot many features of its own to make its product appealing for the users who love to multi-task and want to do a lot more with their phone other than making-receiving calls or playing games. The support for AcerCloud Docs lets the business people wirelessly retrieve their files and Acer Remote Files makes sure that users can also remotely access files from their main PC. Th Acer Float User Interface has been set up to allow using several app windows at once. Moreover, by just pressing a key Float Apps shortcut springs up and then the apps on a translucent screen float over the function being used. Other than that, there's a Float Caller notification that pops up when you get an incoming call, while the Acer Auto Profile makes sure you don't have to fiddle with the network settings. Especially when you are at a frequently visited location, Liquid S1 switched among the predefined profiles for networks.

            


If those features have failed to impress you, let us take you through the mundane routine of the general tech specs - Along with support for Bluetooth, Wi-Fi and 3G, while the photo taking, video recording is made possible using the rear camera, the the front camera with 88° wide viewing angle plus the 24 mm lens can capture Wide Front Shot and do the video calling back home. Thanks to Voice Unlock, users will be able to directly open the apps or interfaces by recording and using personal voice commands. Coming to the audio - there is Studio Sound for an extra-wide stereo image with DTS Studio Sound. The 2-way Live Screen app means users can invite friends for temporary live group sharing.

As Acer puts it, the phone is designed minimally for the target audience of "assertive businesspeople and passionate explorers". And if that involves you, you should know that the Acer Liquid S1 comes in two colors - matte black or white. Starting to ship from third quarter of 2013, the phablet will be available in France, Belgium, Netherlands, Ukraine, Russia, UK and Germany, followed by Spain and Italy. There's no official word about the exact release date or about the U.S. Launch. At a price of €349 (approx. Rs. 26,000), do you think this phone reaches anywhere in the best buy bracket? Let us know your reactions in comments below.

ARM Cortex-A12 CPU & Mali-T622 GPU Aim At 580 Million Mid-Range Devices

The budget-restrained techies have got something really exciting to look forward to. ARM, the mobile processor design giant, is foraying into the mid-range smartphone segment where they've kept a selling target of 580 million devices by 2015. To tone up that segment of $250-$350 prized smarts, the company is developing the ARM Cortex-A12 CPU design that houses future chips to look after your processing requirements while ARM Mali-622 GPU and ARM Mali-V500 video processor shall cater to your graphic needs.

The basic aim for designing these chips into the mid-range devices is to expand all content creation work like video editing, adding special effects creation in photographs, etc in the budget-friendly segment as well. Not only these, but features like natural language processing, handwriting recognition and hardware-based security that's presently enjoyed on high-end models shall be making its way in mid-range too, thus offering the best of both worlds to the customer.

The mid-range chips shall be so designed that they'll also offer a better display pixel resolution, better battery life, better camera quality, increased storage and memory plus additional sophisticated technology. And Cortex A-12's energy-efficient tag makes it the most obvious choice for its inclusion in mid-range smartphones. With support from ARM POP technology and the ARM Development Studio 5 toolchain, ARM partners can deliver smartphones and tablets with higher efficiency and reduced time to market. According to ARM, Cortex-A12 CPU gives 40% better performance as compared to Cortex-A9, while the ARM Mali-T622 GPU is smaller and 50% more energy efficient than Mali-T600 series graphics chips. Mali-V500 video processor supports HD (1080p) processing and is the first ARM design ever to support TrustZone secure video, which offers anti-piracy benefits to video distributors, and disallows protected videos to be decoded/streamed on phone. The chips are expected to be incorporated into mobile devices mid-2014 onwards.

With the power in their hands to be backing the 580 million mid-range mobile devices over the next two years, while keeping in mind the fact that the mid-range market is projected to exceed the number of premium smartphones and tablets beginning in 2015, ARM Architecture is sure taking steps in the right direction. And for the consumers who don't care about flagship devices and are willing to wait till mid 2014, this news could definitely mean something significant. What say you?

மூளைக்கு தீனி போடும் அறிவியல் சமாச்சாரங்கள் - அரியவகை இணையதளம்!!!

இணையத்தில் உலா வந்த போது, சயின்ஸ் ஸ்நாக்ஸ் (Science Snacks) என்ற தலைப்பு சற்று வேடிக்கையாக என் கண்ணில் பட்டது. வியந்து உள்ளே சென்றேன். பின்னர் தான் தெரிந்தது, அங்கு உள்ள செய்திகள் மற்றும் தகவல்கள் அனைத்தும் மூளைக்கு தீனி (ஸ்நாக்ஸ்) போடும் அறிவியல் சமாச்சாரங்கள் என்று. அட, அப்படியா! என நாம் வியக்கும் வகையில், பல அறிவியல் விஷயங்களை இந்த இணைய தளம் நமக்குத் தருகிறது. 



நாம் அன்றாடம் பார்க்கும் சில சாதாரண விஷயங்கள் குறித்து அவ்வளவாகச் சிந்திப்பதில்லை. ஆகாயம் ஏன் நீல நிறமாக இருக்கிறது? சூரியன் உதயம் மற்றும் அஸ்தமனம் ஏன் சிகப்பாக உள்ளது? பிளாஷ் லைட் எரிந்து அணைந்த பின்னர் அதன் இமேஜ் ஏன் நம் கண்கள் முன் தொடர்ந்து சில விநாடிகளுக்குத் தெரிகிறது? இரண்டு உதடுகளுக்கு இடையில் ஏன் சத்தம் வருகிறது? (இப்போது ஏன் உங்களுக்கு ஆர்வம் வருகிறது?)



இது போன்ற சாதாரண விஷயங்களுக்கு நாம் விளக்கங்களைத் தேடி எங்கு செல்வது? பல இணைய தளங்கள் இருந்தாலும், http://www.exploratorium.edu/snacks/index.html என்ற முகவரியில் உள்ள தளம், இந்த கேள்விகளுக்கு நல்ல விளக்கத்தினைத் தருகிறது. இது போன்ற பல விஷயங்கள் இதில் மிகவும் எளிமையாகவும், அனைத்து தகவல்களுடனும் தரப்பட்டுள்ளன.

IIT Madras Develops 'Eye PAC' Software To Help Eye Doctors Work Faster In India!!!

India's leading engineering institute IIT Madras has a Healthcare Technology Innovation Centre (HTIC), a unit of the Research and Development, that has come up with a new affordable eye screening technology called 'Eye PAC' that helps ophthalmologists do their work faster. Up till now, patients with eye problems had to spend a whole day at the hospital for just the screening. With what they've developed here, the process takes just five minutes. Eye PAC is a software that extracts clear information from eyes and in turn help screen a large number of patients and send only the needy ones for further treatment. Thus, the eye doctor can focus on giving immediate diagnostic solutions.

 HTIC unit's head Mr. Mohanasankar Sivaprakasam shared his concern by saying that "Over 80 per cent of cases of blindness in our country are preventable, if only there was no lack of qualified ophthalmologists." Therefore, using the Eye PAC technology what we essentially achieve is the bridging of gap of the shortage of ophthalmologists in the country.



The IIT's HTIC unit has worked on this project by collaborating with the Department of Biotechnology of Government of India. This project also supports '3nethra' -a low cost, portable, and highly integrated ophthalmology device for pre-screening and identification of potential eye diseases, developed by Bangalore-based med-tech firm Forus Health. 3nethra has been already installed in many locations across 10 countries such as India, China, France, Thailand, Sri Lanka, Nepal, Mauritius and Somalia. As we frequently read about the i-tech innovation across the world, in India we are seeing a lot of eye-tech innovation. Recently, we saw how four engineering students from Srinivas Institiute Of Technology, Mangalore came up with 'Eye Mouse' - a hands-free device that aims at letting the differently abled people use mouse on their computer screen in hands-free mode.


 We look forward to more innovative solutions from India's leading technical institutes and organisations. What are your opinions? Share with us in comments.
