GALAXY  S II_3.jpg
The Samsung Galaxy S II is widely believed to be the only real competition to the Apple iPhone. And you can't get it -- yet.

Samsung's mobile division has finally announced a date for the release of its hotly anticipated phone, which has sold lavishly in foreign markets. Over 5 million people worldwide have already bought the flagship Android phone
 in the 85 days it has been on the market -- that's one sold every 1.5 seconds, the company said.

And like Eddie Murphy, it's finally coming to America.Samsung sent an invitation to journalists early Friday touting "a major product announcement" for Aug. 29. The brief note doesn't mention the Galaxy S II by name, but the star-field background and the Roman numeral two clearly suggest what analysts and enthusiasts alike are saying: The Galaxy is coming.

"It isn't rocket science to understand that it's the Galaxy S II announcement," joked Sasha Segan, lead mobile analyst for PCMag.com. Indeed, the name of an image embedded in the announcement speaks for itself, confirming the information the email itself skirts around: Galaxy_S_II_Invite_v2.jpg.

It isn't an understatement to say that the Samsung Galaxy S II is the strongest competition the iPhone faces.
The phone sports a 4.3-inch, 800x480 screen, a 1.2-GHz processor, fast 4G network connectivity, and a sleek, simple design evocative of the iPhone. By contrast, the Apple iPhone 4  has a 3.5-inch, 960x640 screen, a 1-GHz processor, and a slower, 3G connection.

Bigger and faster? Yes, please.

Though it hasn’t gone on sale yet in the U.S., worldwide sales of the Galaxy S II are copious -- practically obscene. In 24 days, the company sold 1 million units -- enough to reach past the top of Mt. Everest if stacked on end. The 2 million units sold in 42 days would fill two and a half soccer fields.

That's a lot of smartphone. But it's more than that: It's a lot of good smartphones, Segan said.

"If the U.S. versions are anything like the international versions, these are going to be spectacular smartphones," he told FoxNews.com. Segan gave an international version of the phone an Editors' Choice award, calling it the finest Android smartphone available today.

The unannounced Apple iPhone 5 is the elephant in the room, of course (and by the way, the 3 million Galaxy S II phones sold in just over 50 days are as heavy as 100 elephants). The iPhone 5 is widely expected to be coming out in September, Segan noted.

And getting the right price could make all the difference for Samsung. "They don't want to be more expensive than the iPhone," Segan said.

It's impossible to compare the stats or pricing for any of these yet-to-be-unveiled phones, of course. But that 4G network connection may prove a major difference between the two. 

"Unless Apple has made some sort of secret breakthrough, [the faster LTE network] might make a Verizon iPhone too thick and power-hungry for Apple's demands this year. Apple may skip it for now and wait for smaller and cooler chipsets," Segan noted. 

That faster connection really pays off for anyone surfing a lot of complicated websites or viewing movies over Netflix, he said.

Details of RIM's first QNX-based "Colt" smartphone leaked

RIM BlackBerry Storm 2 9550
Hot on the heels of Research In Motion's BlackBerry 7 smartphone lineup announcement, technology blog BGR.com has uncovered details of the company's first QNX-based device, a smartphone codenamed the BlackBerry Colt. The BlackBerry Colt will be powered by the same OS as the PlayBook tablet, "which we hope will make RIM competitive in the smartphone industry once again" said BGR.
However, RIM seems to be stumbling further from the front of the smartphone race, even with a bevy of next generation QNX smartphones on its horizon.
"The worst part isn't that the QNX-powered phone won’t be ready until the first quarter of 2012, but that RIM doesn't seem like it has learned from the mistakes from the PlayBook," wrote ZDNet.
According to BGR's tipster, the BlackBerry Colt won't be sporting a uber-fast quad-core or even a dual-core processor on launch. It will have a single core 1 GHz processor which, as ZDNet notes, puts it behind its already launched Android and iOS rivals.
Another complaint is the phone's initial lack of support for BlackBerry Enterprise Server, RIM's corporate email solution.
"If companies want to use Microsoft Exchange email on the device, they will actually have to use Microsoft ActiveSync," said BGR.
One saving grace for RIM is that the BlackBerry Colt is still in testing and the specifications could easily change before the device's release.

Facebook aims to replace texting

Image representing Facebook as depicted in Cru...

Facebook has launched an instant messaging service for mobile phones, similar to BlackBerry Messenger.
The dedicated app, for iPhones and Android devices, allows users to contact individual friends or groups of people.
Its release comes a month before Apple is due to unveil a similar product.
Attention has been focused on mobile messaging recently because some of the London rioters were known to have used it to co-ordinate their movements.
So far Facebook's mobile messenger is only available in the United States, but it is expected to eventually roll out in other countries.
The social network's 750 million users already have the ability to send messages through the website, and on Facebook's original smartphone app.
Its new application adds the option to send directly to a mobile phone via SMS, and also to include location information.
Bad timing?
Facebook's timing has raised a few eyebrows within the industry, given the debate around BlackBerry Messenger's role in the recent UK rioting.
However, it is likely that its decision to launch in the US now was influenced by the impending Arrival of Apple's iOS 5 and its integrated messenger.
Stuart Miles, the founder of Pocket-lint.com, told BBC News that Facebook might be able to make mileage out of its compatibility with more than one phone system.
"Apple will be iPhone to iPhone, like Facetime. The same as BBM which is Blackberry to Blackberry. [Facebook] will be Android to iPhone, so theoretically it can only benefit from the platform," said Mr Miles.
"The big question you have to ask is how long will it be before Google+ has a messaging service built-in."

BlackBerry's QNX-Based Phones Expected to Underwhelm Users

The BlackBerry Storm 9530 smartphone.

If you were keeping your hopes up for a BlackBerry superphone running theQNX OS, you will be disappointed. Research In Motion is set to launch an underwhelming range of QNX-based phones next year, according to a BGR report, that will be as good as dead on arrival. Here's why:
Most smartphone manufacturers today are placing their bets on dual- or multicore CPUs for their devices, such asSamsung's Galaxy S II, Motorola's Atrix, and even the next-generation iPhone, rumored to run on the same A5 dual-core processor found in the iPad 2. However, Research In Motion plans to launch a single-core device next year that runs on the future QNX OS, currently found on the PlayBook tablet from the company.
The first QNX-based RIM phone is codenamed the BlackBerry Colt, according to BGR, whose sources are mostly spot-on, but sometimes way off. The phone is expected to arrive in the first quarter of 2012, and besides being hobbled with a single-core CPU, it will launch without supporting BlackBerry's Enterprise Server. This means that in order to use Exchange e-mail on the device, Microsoft's ActiveSync will need to be used.
RIM seems to be repeating past mistakes. Case in point: the PlayBook, which was rushed to the market and then deemed half-baked because of the lack of a native e-mail client and buggy software. RIM still has time to make improvements to upcoming QNX phones, but it seems that a multicore CPU is not on the table.
QNX BlackBerry models following the Colt will probably sport dual-core processors, but given RIM's slow demise in smartphone market share, the company has few ropes to hold on to. Until 2012 though, we will see another generation of dead-on-arrival BlackBerrys this fall that are gunning for the iPhone with specs matching last year's model.

Anti-matter around Earth discovered

Planetary scientists claim to have for the first time spotted a thin band of anti-matter particles, called anti-protons, enveloping the Earth. The find, published in the "Astrophysical Journal Letters", confirms theoretical work that predicted the Earth's magnetic field could trap
Original raster version: 100pxImage via Wikipedia
antimatter, according to a team led by the University of Bari.
The astronomers say that a small number of anti-protons lie between the Van Allen belts of trapped "normal" matter.
The anti-protons were spotted by the Pamela satellite launched in 2006 to study the nature of high-energy particles from the Sun and from beyond our Solar System - so-called cosmic rays, the 'BBC' reported.
These cosmic ray particles can slam into molecules that make up the Earth's atmosphere, creating showers of particles. Many of the cosmic ray particles or these "daughter" particles they create are caught in Van Allen belts, doughnut-shaped regions where the Earth's magnetic field traps them. The new analysis shows that when Pamela passes through a region called the South Atlantic Anomaly, it sees thousands of times more anti-protons than are expected to come from normal particle decays, or from elsewhere in the cosmos.
 The astronomers say this is evidence that bands of anti -protons, analogous to Van Allen belts, hold anti-protons in place -- at least until they encounter the normal matter of atmosphere, when they "annihiliate" in a flash of light.

The band is "the most abundant source of anti-protons near the Earth", said Alessandro Bruno, team member.
"Trapped anti-protons can be lost in the interactions with atmospheric constituents, especially at low altitudes where the annihilation becomes the main loss mechanism. Above altitudes of several hundred kilometres, the loss rate is lower," he added.

Building Blocks of DNA Found in Meteorites from Space

The Willamette Meteorite on display at the Ame...

The components of DNA have now been confirmed to exist in extraterrestrial meteorites, researchers announced.
A different team of scientists also discovered a number of molecules linked with a vital ancient biological process, adding weight to the idea that the earliest forms of life on Earth may have been made up in part frommaterials delivered to Earth the planet by from space.
Past research had revealed a range of building blocks of life in meteorites, such as the amino acids that make up proteins. Space rocks just like these may have been a vital source of the organic compounds that gave rise to life on Earth.
Investigators have also found nucleobases, key ingredients of DNA, in meteorites before. However, it has been very difficult to prove that these molecules are not contamination from sources on Earth.
"People have been finding nucleobases in meteorites for about 50 years now, and have been trying to figure out if they are of biological origin or not," study co-author Jim Cleaves, a chemist at the Carnegie Institution of Washington, told SPACE.com.
To help confirm if any nucleobases seen in meteorites were of extraterrestrial origin, scientists used the latest scientific analysis techniques on samples from a dozen meteorites — 11 organic-rich meteorites called carbonaceous chondrites and one ureilite, a very rare type of meteorite with a different chemical composition. This was the first time all but two of these meteorites had been analyzed for nucleobases.
The analytical techniques probed the mass and other features of the molecules to identify the presence of extraterrestrial nucleobases and see that they apparently did not come from the surrounding area.
Two of the carbonaceous chondrites contained a diverse array of nucleobases and structurally similar compounds known as nucleobase analogs. Intriguingly, three of these nucleobase analogs are very rare in Earth biology, and were not found in soil and ice samples from the areas near where the meteorites were collected at the parts-per-billion limits of their detection techniques.
"Finding nucleobase compounds not typically found in Earth's biochemistry strongly supports an extraterrestrial origin," Cleaves said.
"At the start of this project, it looked like the nucleobases in these meteorites were terrestrial contamination — these results were a very big surprise for me," study lead author Michael Callahan, an analytical chemist and astrobiologist at NASA Goddard Space Flight Center, told SPACE.com.
Lab experiments showed that chemical reactions of ammonia and cyanide, compounds that are common in space, could generate nucleobases and nucleobase analogs very similar to those found in the carbonaceous chondrites. However, the relative abundances of these molecules between the experiments and the meteorites differed, which might be due to further chemical and thermal influences from space.
This findings  reveal that meteorites may have been molecular tool kits, providing the essential building blocks for life on Earth, Cleaves said.
"All this has implications for the origins of life on Earth and potentially elsewhere," Callahan said. "Are these building blocks of life transferred to other places where they might be useful? Can alternative building blocks be used to build other things?"
In a different study, researchers discovered molecules that make up key parts of a vital biological pathway, the citric acid cycle, in a number of carbonaceous chondrites.
The citric acid cycle is "thought by many experts to be among the most ancient of biological processes," study co-author George Cooper, a chemist at NASA Ames Research Center, told SPACE.com. "One function of this cycle is respiration, when organisms give off carbon dioxide."
"It is always exciting to find extraterrestrial and ancient 4.6 billion-year-old organic compounds that might have had a role in early life," Cooper added.

Mac OS X Lion: Big cat ahoy

Image representing Apple as depicted in CrunchBase
OS X Lion arrives nearly two years after Apple launched its previous Mac operating systemOS X 10.6 Snow Leopard. The first thing that’s apparent is the change in nomenclature. Gone is the version number (in this case 10.7) from the name.


Lion is currently only available on Apple’s App Store for an upgrade price of $29.99 (Rs 1,330 approximately). At a hefty file size of 3.5GB, people with slow internet connections will find downloading it a chore. Once downloaded, double-clicking on the file will initiate the upgrade. Back up the file, as it will be deleted once Lion has finished installing.

The first thing you’ll notice about Lion is its appearance. From buttons and folders to icons and sliders, everything looks more understated and subdued compared to the previous OS. In fact, sliders aren’t present at all, until you move your finger over the touchpad or mouse. Full-screen mode is now available in all pre-installed apps like Safari and Mail, and each instance arranges itself on another desktop.

The mail, calendar and contacts applications have been redesigned, heavily taking cues from the iPhone and iPad. The upgrade to Mail is especially important and very convenient.

Mac OS X logo
Auto Save, a new feature toted by Apple, promises that you never need to save a file again. Lion automatically saves separate versions of the file you’re working on, such as a document or spreadsheet, in the background. It even allows you to access different versions Time Machine-style. Two computers using Lion can also share files wirelessly via Airdrop. This feature works over Wi-Fi and doesn’t require a host connection like a router or access point.

Lion will only install on 64bit computers, and brings with it a host of important upgrades, redesigned keeping uniformity with the iPhone and iPad in mind. The R 1,330 price tag is very affordable and it makes complete sense to upgrade your Mac to Lion. Apple will sell OS X Lion on a USB drive soon, but until then, you have no choice but to download the file.

LaunchpadIf you’re familiar with Apple’s mobile operating system, iOS, even the littlest bit, you won’t have the slightest problem with Launchpad. This feature takes all your applications, even those stored in the home directory Applications folder, and displays them iOS-style. Folders and apps are displayed in the same way as those in the iPhone/iPad and can even be dragged and dropped onto multiple screens.
Screenshot of Mac OS X Snow Leopard, released ...
Mission Control
Window management is something that Apple takes very seriously. ‘Exposé’, which was released a few editions ago, shows you all open documents and programmes when invoked. ‘Spaces’ allows for multiple desktops and ‘Dashboard’ lets you access various widgets. Mission Control now combines them all on one screen. Accessed via the dock, or keyboard button/shortcut, you can now see all open applications, desktops and widgets on the same screen. This step was only natural and works brilliantly.

Chevrolet Beat Diesel : Road Test


It was waiting to happen but no one did it, a small diesel in the small hatchback category. What makes it even more interesting is that none other than a company with its back to the wall plucked deep within itself, thought logically and smartly for a change and came up with an engine and matching aggregates to not just put new life into the funkiest of its global minicars but that this exercise was done in India, predominantly for our needs and from there on to the rest of world, which as they say is its universal dancing ground. Adil Jal Darukhanawala taps into the smallest diesel-engined car in the country, saying that Chevrolet has changed the rules of engagement forever
When the Chevrolet Beat first hit enthusiasts’ minds as a concept car many moons ago, it was right there as a funky youth-oriented global offering and this bit yet stays true. Of course, while the product was A-OK, the perception levels regarding its parent were anything but and many of GM’s products suffered on this count as the company had to fight raging fires on so many fronts. In this period of global turmoil, the Indian arm of GM made itself financially secure with some deft footwork. Immediately from thereon it set into motion a series of product development initiatives which focused on product, product and even more product so as to be a complete portfolio player in the Indian market. As is a no-brainer in this country, diesel was paramount in the thought process for the GM India team. 

Karl Slym and his team knew that they had to consider a small capacity diesel engine sooner rather than later if GM had to not just get critical mass to be in the reckoning but also that its efforts would have a spill over effect in the Asia-Pacific region as well. What marked out GM’s way of working out a small diesel engine was its going against prevailing convention to come up with not just the country’s smallest passenger car engine but also to make it work. Where others have dabbled with engines ranging from 1.3 litres and upwards, the GM team (including specialists at GM Europe and also GM R&D in Bangalore) went through the existing hardware within the GM empire and zeroed in on the 1.2-litre four-cylinder Opel SDE motor. The idea was to put into motion the downsizing mantra which has energised every car maker on the planet but without sacrificing torque and driveability and thereby ensuring high fuel efficiency and low tail pipe emissions.

DRIVETRAIN

Many a time I have experienced small petrol and diesel engines, which have been poorly developed for fuel efficiency just because they displace less volume. In doing so they also compromise driveability and that is the key to good fuel efficiency. The new GM engine, designated the 1.0 XSDE Smartech, is a departure from this line of thought. First the basic architecture of this unit consists of a short skirt cast iron block for its three cylinders, the GM boffins lopping off one cylinder from the 1.2-litre base SDE unit. This long stroke engine, with 936cc displacement (courtesy bore and stroke dimensions of 69.7mm x 82.0mm) has an alloy cylinder head packed with double overhead camshafts operating four valves per cylinder. 


The engine works on a 16.5:1 compression ratio and employs the latest Bosch CP1H common rail direct injection technology, squirting diesel into the combustion chambers at 1600 bar and working in conjunction with a Borg-Warner KP31 fixed geometry turbocharger to provide a punchy 150Nm of torque (at 10750rpm), which as it stands does all the talking and more to make this Beat dance and sing. For the record the engine makes 58.5PS at 4000rpm and these power and torque figures are impressive in themselves for they make the Beat deliver best in class outputs: 62.5PS per litre and a whopping 160.3 Nm per litre of displacement!
