Until now, personal cinema devices have been notoriously bad: it simply wasn’t possible to fit nice screens into an acceptably small form factor. The advent of OLED screens has changed all that, and we’re about to see a resurgence in these virtual cinemas. The  HMZ-T3W  is Sony’s latest attempt – but is it a premium futuristic personal display or just a silly head gadget? Read on to find out! The  Sony HMZ-T3W Personal 3D Cinema  retails at around $1000 – the biggest feature addition in this newest model being the ability to transmit HD content wirelessly from the powered base station. There’s a huge range of competing virtual screen devices you can find in the market, the best of which appears to be the  Carl Zeiss Cinemizer  at around $800; sub-$400 models like the Vuzix Wrap 920VR  are generally have poor reviews. Before I tell you about the HMZ-T3W, let me give you some context. Most of my movie viewing is done on a 47-inch wall mounted...

Contrary to popular belief, pictures found on Google Images are  not  free to use any way you want. Google has recognized this belief is widespread, so they have now implemented a new filter in their search results that will show you the images which are legal to use. Using it is very simple. After entering your search term, click on the “ search tools ” option in the menu bar. That will drop down to reveal more options, including “ Usage Rights “. Then choose the license you are looking for, and the search results will update instantly. The first results are often from Wikipedia (or associated pages). According to 9to5 Google,  it is not clear how Google identifies which images are legal and which ones are not. But it’s pretty safe to say that anything on Wikipedia is free to use, and with the rest, it would be good to cover yourself legally by linking to, and crediting, the image owner in your work. Eventually Google will probably clarify how it categorizes ...

The Rubik’s cube is one of those puzzles that are endlessly fascinating to people of all age groups. But, trying to solve it for the first time can be an exercise in frustration. If only there was an easy way to learn how. Well, as it happens, there is. I’m a first-time cuber myself, if you ignore my previous attempts to solve the puzzle by idly twisting the cube this way and that, without applying an ounce of thought or logic. Driven by the desire to learn to solve the Rubik’s cube, I decided to start afresh, this time with more focus and practice. As expected, the Web provided endless interesting content on the topic. Where I Began My Quest I started my search for information with Saikat’s article on  websites to solve the Rubik’s cube . Things just snowballed from there and I ended up with page after page of tricks and algorithms. Finally, I narrowed down a few simple methods recommended for beginners and put them to the test. As I found out, there is indeed a method ...

Google announced on Monday that it has entered into an agreement to buy Nest Labs, Inc., makers of the Nest learning thermostat and Nest Protect, a connected smoke detector. The deal will cost Google $3.2 billion and should close in the next few months. Nest has always been on Google's radar. Google Ventures, the company's startup investment arm, was one of the Nest's early investors. Google was previously rumored to be building a Nest thermostat competitor, and there were even leaked screenshots of a smart thermostat app built by Google called "EnergySense," which would let you control the temperature from a smartphone or Web client. Now that Google is buying its main theoretical competition in this area, it's unclear what will happen to Google's internal projects. The one thing we do know is that the Nest brand will be sticking around, and the CEO of Nest, Tony Fadell, will continue to run the company as a separate division in Google. Nest has a...
