Which GPU is Right For You?

If a laptop’s brain is the CPU, than consider the GPU the occipital lobe. Responsible for rendering images, video and animations in either 2D or 3D for the display, the chip performs rapid mathematical computations, freeing up the processor for other tasks. Where a CPU consists of a few cores focused on sequential serial processing, GPUs pack thousands of smaller cores designed for multitasking.

AI-based typing biometrics might be authentication’s next big thing

Research in the field of keystroke dynamics spans decades.


Identifying or authenticating people based on how they type is not a new idea, but thanks to advances in artificial intelligence it can now be done with a very high level of accuracy, making it a viable replacement for other forms of biometrics.

Research in the field of keystroke dynamics, also known as keyboard or typing biometrics, spans back over 20 years. The technique has already been used for various applications that need to differentiate among computer users, but its widespread adoption as a method of authentication has been held back by insufficient levels of accuracy.

Keystroke dynamics relies on unique patterns derived from the timing between key presses and releases during a person’s normal keyboard use. The accuracy for matching such typing-based “fingerprints” to individual persons by using traditional statistical analysis and mathematical equations varies around 60 percent to 70 percent, according to Raul Popa, CEO and data scientist at Romanian startup firm TypingDNA.

Teaching computers to understand human languages

Teaching computers to understand human languages

Researchers at the University of Liverpool have developed a set of algorithms that will help teach computers to process and understand human languages.

Whilst mastering natural language is easy for humans, it is something that computers have not yet been able to achieve. Humans understand language through a variety of ways for example this might be through looking up it in a dictionary, or by associating it with words in the same sentence in a meaningful way.

The algorithms will enable a computer to act in much the same way as a human would when encountered with an unknown word. When the computer encounters a word it doesn’t recognise or understand, the algorithms mean it will look up the word in a dictionary (such as the WordNet), and tries to guess what other words should appear with this unknown word in the text.

Semantic representation

It gives the computer a semantic representation for a word that is both consistent with the dictionary as well as with the context in which it appears in the text. In order to know whether the algorithm has provided the computer with an accurate representation of a word it compares similarity scores produced using the word representations learnt by the computer algorithm against human rated similarities.

Liverpool computer scientist, Dr Danushka Bollegala, said: “Learning accurate word representations is the first step towards teaching languages to computers.”

“If we can represent the meaning for a word in a way a computer could understand, then the computer will be able to read texts on behalf of humans and perform potentially useful tasks such as translating a text written in a foreign language, summarising a lengthy article, or find similar other documents from the Internet.

“We are excitingly waiting to see the immense possibilities that will be brought about when such accurate semantic representations are used in various language processing tasks by the computers.”

Watch this tinkerer get Windows 7 running on an LG G Watch

We really do live in the future, don’t we?Hacking Jules, a prolific hacker with a YouTube channel devoted to installing different operating systems and classic games on random mobile devices, posted a video of an LG G Watch running Windows 7 about a week ago.

The video is not easy to watch. For starters, the mouse tracking for Windows 7 is incredibly slow, not to mention that the entire interface is shrunken down to tiny icons on the G Watch’s 1.65-inch display. The video also cuts through the three hours it takes to boot up Windows 7.

If you’ve got the patience and you want to try the hack yourself this weekend, there’s a full tutorial available. Otherwise, just marvel at the fact that our technology’s become so powerful, that even a small smartwatch can run a full-blown desktop operating system.

Windows 10 phones gaining support for fingerprint readers this summer

Lumia 950XL Windows Hello
The Lumia 950XL and its red iris reader can log you in using Windows Hello.Microsoft’s improving the biometric login capabilities of Windows 10 Mobile in the coming months. The company plans to add fingerprint sensor capabilities to Windows Hello—the biometric login feature built into the operating system—in the mobile version of Windows 10 this summer. Windows 10 Mobile already supports retina detection, which is used by the Lumia 950 and the 950 XL.

Microsoft revealed its plans for fingerprint sensing during the Windows Hardware Engineering Community (WinHEC) planning event, which was held in China in March. Earlier this week, Microsoft released its presentation slide decks from the events on Channel 9, allowing the public to find out about its plans.

To use the new fingerprint scanning capability your phone will have to come with the hardware required to use it. The first handset to use the fingerprint capability will likely be HP’s Elite X3. The company previously announced it would offer “dual biometrics” on the phone with iris detection and fingerprint scanning.

Why this matters: Unlocking your phone with a retina scan feels cool and very futuristic—almost Mission Impossible-like, you might say. But it’s also an impractical feature, at least in my experience on the Lumia 950. Retina scans are far slower than entering a PIN, to the point that I often forget the feature is there and just quickly zip through my code instead. Retina scans also don’t work at all when you’re outdoors on a sunny day. Fingerprint scanning, meanwhile, tends to be very responsive, and many hardware makers already have experience with the technology.

Flexible lighting foils for next-gen electronics developed

Scientists have used a focused beam of electrons to create some of the smallest nanowires ever made.
ENEVA: Scientists have developed rolls of flexible lighting foils that can be produced much like newspapers are printed, paving the way towards cheaper solar cells, LED panels and next generation of flexible electronics.The Tresores project (Transparent Electrodes for Large Area Large Scale Production of Organic Optoelectronic Devices), led by Frank Nuesch of Swiss research institute Empa, aims to dramatically reduce the production costs of organic electronic devices such as solar cells and LED lighting panels.

The project developed and scaled up production processes for several new transparent electrode and barrier materials for use in the next generation of flexible optoelectronics.

Intel outlines a plan to get back in line with Moore’s Law

Intel hopes to get back to advancing the chip manufacturing process every two years with the upcoming 7-nm process.

Intel Skylake chip.

Intel prides itself on making computers faster, cheaper and smaller, but in recent years, the company lost a chip manufacturing edge it had to make that happen.

The company hasn’t kept up with its own deadlines to advance chip technology and has dealt with embarrassing product delays. In recent years, Intel hasn’t been able to advance the chip manufacturing process on a regular two-year cycle, a schedule it had in place for decades.
