An enthusiast-class digital camera with brilliant optics
Canon’s PowerShot G-series of compact digital cameras has everything it takes to bring smiles to enthusiasts. Tough build, brilliant optics, lots of external controls and stellar performance are only a few of the many great things about the cameras belonging to the series. Previous addition to the G-series was the G1 X, which was the first of its kind—a compact digital camera with a 1.5-inch type sensor (almost as large as ones found in entry-level DSLRs). The latest addition to the series is the G15, which is an upgrade to the G12 that was launched in 2010. Let’s find out what it packs in its compact shell and how much better it is than the G12 and its competitors.

Features and design
If you already own a G12, the list of upgrades will tempt you to go in for the G15. At 11.7-inch, the size of the sensor used in both the models is larger than the usual 12.3-inch type sensors used in mainstream digital cameras. However, the resolution has been bumped from 10 to 12.1 megapixels and the sensor used is of the CMOS type instead of CCD. The optics used in the G15 is to die for! The lens used in the G12 was 28 mm at the wide end and extended to 140 mm, thus translating to 5x optical zoom. G15 too uses a 5x zoom lens with the same focal length, but it’s way brighter. At the wide end, G12 had a fairly large f2.8 aperture, which narrowed to a pedestrian f4.5 at the telephoto end—quite respectable. The G15 has a large f1.8 aperture at the wide end, and you can stick to f2.8 throughout the zoom range. This allows handheld shooting in low light without having to use flash. Also, the shallow depth of field or background blur is very well pronounced when you shoot using the largest aperture, especially in macro mode wherein you can shoot from as close as 1 cm from the subject.

Next in the list of upgrades is the display. A bump from a mediocre 461k dot to 922k (twice as dense) is a welcome change. It has been noted that while Canon upgrades or adds new features, it takes away some useful features. For instance, the G12 had a fully articulating display that allowed capturing creative shots from odd angles. The G15 does away with this feature and uses a fixed display, which seems to have been done to make the camera slimmer. This has helped making the G15 slimmer than the G12 by 8 millimetres. The width too has shrunk by 5 millimetres. However, at 107 x 76 x 40 mm, the G15 is just about pocketable—you’d feel more comfortable having it hanging around your neck than carrying it in your trouser pocket. This shrink in size has helped Canon bring down the weight of the camera by around 50 grams; the G15 weighs 352 grams with the li-ion battery loaded. Other minor upgrades include full HD video recording from 720p in the G12, a slightly improved EV range (±2 to ±3) and an increased ISO range. If you’re in extremely low light, you can set the ISO to as high as 12800 for steady handheld shots.

Design-wise, the G15 looks very similar to the G12, except for the subtle changes when you view it from the front. The rubberised grip is slightly larger because the horizontal dial now uses less space. Also, the top right corner is now empty because Canon has chosen to go in with pop-up type flash—there’s a tiny lever behind the flash that releases it. The top panel of the G15 looks empty when compared to that of the G12. The latter had a dial for EV in place of which there’s now the pop-up flash. This has now been shifted to the right, below the mode dial. The G12 had a third dial to select ISO speeds in one-third steps, on which the mode dial was stacked. The G15 has a shortcut for ISO on the D-pad instead, which isn’t as handy as a dedicated dial.

The rear of the camera is dominated by the 3-inch LCD display. To the right lies the control panel that comprises a 5-way D-pad with a jog dial and buttons for metering modes, focus area and menu. The button with the asterisk icon, when pressed, automatically sets the optimal aperture and shutter speed. The portion above the LCD is home to an optical viewfinder (with dioptric adjustment) and playback button. A dedicated button for video recording is placed at the top right corner, next to the rubberised thumb grip.

Build quality and ergonomics
The build quality of the G15 is impeccable—right from the buttons and flaps to the shell. The front of the shell is made of aluminium and has a rough, grainy finish that lends a rugged feel. The rubberised grip on the front coupled with the thumb grip lends a firm grip even while using the camera single-handed. Plenty of external controls and their ergonomic placement contribute to fatigue-free shooting. What we found most useful was the second dial on the front—it comes in very handy when you want to adjust the aperture and shutter speed. In playback mode, it skips a bunch of pictures at a time when rotated one notch at a time.

The intuitive user interface makes the G15 easy to use. The mode dial lets you select from Auto, PASM, Scene, Creative filters and Movie modes. You use the Menu button to bring up the stack of parameters on the left side of the screen and then navigate/select values using the D-pad and jog dials—very straightforward, without having to delve into menus and sub-menus. 

The Scene mode has limited but the most useful presets including portrait, smooth skin, hand-held night scene, snow and fireworks. The Creative Filter mode lets you shoot photos using effects such as HDR, Nostalgic, Fish eye, Miniature, Toy camera, Monochrome and Color accent—again the most common ones that you’d want to use. Many of the effects are configurable, for instance, Nostalgic and Toy camera modes that allow changing the colour tones.  The G15 can record videos at full HD and even shoot super slow-motion videos.

The battle of flagship smartphones is a never ending story. Each year, a new chapter begins and we kick off 2013 with the HTC Butterfly vs Sony’s Xperia.
Mobile Grudge Match: HTC Butterfly vs Sony Xperia Z
The battle of flagship smartphones is a never ending story. Each year, a new chapter begins and we kick off 2013 with the HTC Butterfly vs Sony’s Xperia Z. Both these handsets mirror the absolute best of what their respective manufacturers have to offer with today’s technology. Let’s take a quick look at each of them before we put them in the ring for a face-off.

HTC Butterfly 
The Butterfly managed to impress us quite a bit and despite its poor battery life, we do think it’s one of HTC’s best attempts yet. Some of the features that would make us run out and buy one despite its shortcomings are the camera and the display. Along with the awesome burst mode that made the One X a huge success, HTC has packed in a better 8MP sensor with a very large aperture of f/2.0. Not only does this improve the level of detail for low light shots, you can really have fun with the amount of depth of field you get in macro shots. The level of details captured is also a lot better compared to its previous flagship. The display is superb as well and even though we feel 1080p for a smartphone is pushing it a bit, it’s still a gorgeous display thanks to the Super LCD3 technology.

Sony Xperia Z
Sony has finally upped its game and the Xperia Z shows that the company means business. The Z is very similar to the Butterfly in terms of specifications as it also has a 1080p screen, quad-core CPU and full HD capable front facing camera. The similarities end here though, as the Z raises the bar by offering a massive 13MP camera sensor, is a lot slimmer than the Butterfly and best of all, has passed the IP55 and IP57 certifications, which officially makes it dust and water resistant. Sony claim that the Xperia Z will easily work up to 1 metre underwater and for up to 30 minutes. All this from a phone that still manages to look every bit as glamorous as, say, the iPhone 5.

It’s now time to put these two flagships in the ring and see which one looks like the better option, at least on paper.

The bottom line 
Since both the handsets are extremely similar, it’s a very close match. In the end though, the Xperia Z manages to edge out the Butterfly and that’s the phone I’d go with too, given the choice. Aesthetics is very subjective and both handsets are a head turner. However, the glass-laden back of the Z should give it a little more street cred. The main reason why I would personally pick the Sony over the HTC is the IP57 certification and due to its slightly larger battery, which should help prolong the need to recharge. Being water resistant means you don’t have to worry about protecting it during monsoons, or if it gets a bit dirty, simply wash it under a tap. More than wireless charging and other such gimmicks, I feel every flagship smartphone from now on must have an IP57 certification as it’s a feature that truly impacts the way we use high-end phones. 



Although there are some solid small form factor cases available, none of them are perfect -- at least not if you're Wahaha360 and Necere from HardOCP's forum. Disappointed by popular enclosures such as theSilverStone SG05, the guys teamed up last year to design their ideal chassis. After months of feedback from HardOCP members and Lian Li engineers, the pair have unveiled the fruits of their labor: the NCase M1.
Some of the M1's specs could change by the time it hits production, but on paper, the 12.59-liter box has the features you'd expect from a standard enthusiast chassis. At 160 x 328 x 240mm (250mm with the feet -- 6.29 x 12.91 x 9.44in), the case is designed for Mini-ITX motherboards, which is more compact than MicroATX at 170mm long versus 244mm and allows the M1 to house a power supply in a unique top front position.
Besides supporting standard ATX power supplies, the M1 can accommodate a triple-slot graphics card up to 317.5mm (12.50in) long, a processor cooler up to 105mm (4.13in) tall, four 120mm fans and one 80/92mm fan, dual 120mm radiators, as many as three 3.5in or four 2.5in storage drives, and one slim slot-loading optical drive. The front panel carries two USB 3.0 ports and audio jacks around a central power button.
As we hinted above, the M1 is still in a prerelease phase. NCase wants to have two prototypes made by Lian Li soon, but they need a few bucks to get started. The team is asking for $3,000 via Indiegogo and they're a little over halfway there with four weeks to go. Once the prototypes are created and the design is refined, NCase plans to gather funding for a limited production run where the M1 will be sold for $160 to $200.
There are only four donation tiers: $1 gets you a pat on the back, $5 earns you a mention on NCase's site, $10 puts you on a priority shipment list for the production run and $2,000 scores you a prototype when NCase is done testing. Besides helping two enthusiasts build their dream case, NCase says backing the project will prove to companies that getting involved with the community can break stagnation and promote innovation.

Depending on what you are doing, a computer crash can be classified as anything from a minor annoyance to a complete disaster. I’ve been experiencing some BSODs lately of unknown origin and let me be the first to tell you, it’s pretty darn annoying when you are right in the middle of something important – like work – and everything shuts down before you get a chance to save.
Fortunately, researchers and scientists at the University College London have come up with a solution they say will end computer crashes forever.
Today’s computers typically work procedurally by pulling data from memory, working on the data then sending it back to memory. This usually happens in a fixed order and until something goes wrong, all is well. When a process fails or crashes for whatever reason, however, everything hits the fan and the computer will often times lock up.
The computer that UCL has developed is different in the fact that data and instructions are essentially mirrored across several different systems. The systems work simultaneously although independent of each other – the only thing they share is a section of memory for context-sensitive data.
In the event that one system crashes or data becomes corrupted, the computer is able to rebuild that set of data from another system and start fresh again. The systems are said to execute in a random order using a pseudorandom number generator that acts as a task scheduler.
At this point, performance isn’t all that great but there’s certainly room to improve upon. If you’re interested in learning more about this developing technology, the developers will present their findings at the IEEE International Conference on Evolvable Systems in April.

Microsoft’s research lab in Cambridge, UK has developed a new way to interact with the digital world using intuitive hand gestures. “Digits” uses 3 different IR cameras to track the positions of fingers with respect to each other.
One of the applications for this technology includes 3-D spacial interaction with a mobile device. By assigning gestures to certain functions, the user could conceivably control any aspect of a device. This also allows for vision free control of the device. In example used in Microsoft’s video, they assigned the the “thumb’s up” to answer an incoming call.
Other applications include sign language interpretation and endless possibilities for gaming. Could this be the new controller for XBox 720? Guess we will have to wait to find out.Microsoft Digits - 3D Hand Gesture Computer Interaction

Microsoft’s Surface Pro tablet hit retail shelves last Friday but you wouldn’t know it if you happened to venture into any number of big box stores this weekend. That’s because the slate was nowhere to be found – sold out in virtually every location, we’re told.
Both the 64GB and 128GB units were sold out online through Microsoft’s website by Saturday. All of this could mean one of two things: either Microsoft had a fantastic sales weekend or they didn’t ship nearly enough tablets to fill demand. At this time, it appears that the latter might be the more likely scenario.
Why exactly would Microsoft intentionally release the Surface Pro in short supply? For the same reason that a number of other companies have been accused of doing – to create buzz and further build demand. We aren’t saying that is what happened, but others are certainly making that accusation.
Richard Hay from Windows Observer did some investigation and found that one store said they only received one model each of the Surface Pro (64GB and 128GB). Another store said their shipment never made it in time for the retail launch while another retailer noted they only received five of each tablet. A number of locations told him they didn’t have any display models of the tablet or only had the 64GB model on display.
Of course, it’s also entirely possible that the shortage is due to higher than anticipated demand. ZDNet points out that Microsoft didn’t take any pre-orders for the device like they did with the Surface RT devices. It’s unclear why Microsoft wouldn’t hold pre-orders, however. Hopefully we will know more sooner rather than later but it’s not likely that the company will release sales figures unless they are astronomical.

Fueled by sources purportedly familiar with Cupertino's developments, a report by The New York Times indicates Apple's rumored wristwatch-like device will feature curved glass. Rumors suggest the "iWatch", as it is being called for now, could enter production as early as this year.
Interestingly, Apple was issued a patent in December for a novel process which yields high-quality, curved glass. Could the company be leveraging this technology for their iWatch? Perhaps.
Two of the Times' sources also claim that Apple's iWatch will stand apart from the competition based on the company's understanding of how glass can curve around the human body. Could this also mean flexible glass? Although Apple's patent doesn't touch on flexible glass specifically, companies like Corning are able to produce flexible glass composites like Willow Glass -- a watch may be an interesting use for such a material.
Smartwatches are hardly new, but an impressive crop of increasingly sophisticated wrist-mounted devices made their way to CES this year. Thus far, manufacturers have managed to stuff social networking features, texting and even calling capabilities into these tiny wrist-hugging devices.
Rumors suggest the iWatch will feature a 1.5-inch passive display, Bluetooth 4.0 connectivity and of course the latest addition: curved glass. However, little else is known (or thought to be known) about Apple's possible smartwatch entry. Will it be a directions-giving, Siri-backtalking, app-installing, iOS-based cellular device? Or will the iWatch merely be a wrist-wearable iPod Shuffle? It is simply too early to tell.
