Google Glass Review: Functions and Flaws

There has been a lot of hype over one of Google’s latest gadgets – Google Glass. The multi-billion dollar company never fails to create huge excitement around their products, which is evident in this case by their impressive video trailer “How It Feels [through Glass]”

It’s easy to get really excited about Google Glass after watching something like this. The song alone almost makes you want to go ski-diving and start living a fuller life.

However, since Google Glass became available to more ordinary folk (at a price tag of $1500), several videos have since surfaced that highlight the inherent flaws in this technology. A Google Glass review by Engadget mentions some of these shortfalls.

It is also not mentioned that Google Glass requires a wireless connection to your smartphone (which comes at an additional cost). Users have also reported that battery-life is really only a few hours and that the device needs to be charged often via a micro USB.

Functionality also seems to be quite limited with this early edition of Google Glass. You can’t browse webpages or make use of any apps at this point. What Google Glass does allow you to do is check weather forecasts, take pictures and videos (and share these), do basic searches, read and reply to emails or messages, hang out on Google+, get directions, tell you the time and respond to voice prompts. I’m sure there are a few more functions of Google Glass, but at this point, it is essentially a low-end smartphone for your face.

There’s no doubt that Google Glass will evolve into something more impressive over time, but it is also most likely that credit for this will be due to non-Google developers and rather users of the technology – a cheap and effective method of outsourcing. But at least Google has planted the seeds for a possible future behind a screen.

Does the Internet impair our ability to concentrate?

ARGUMENT: The Internet impairs our ability to contemplate and concentrate for long, sustained periods of time

AN ex-colleague of mine (Ryan Calder) started an interesting debate about the Internet on Facebook. He was asking whether or not people thought that the Internet (and cyber culture in general) impairs our ability to concentrate. Some of the comments were quite interesting.

Embracing Change

THE world is changing pretty fast – exponentially in many cases, particularly in the technology and online industries. It’s natural for anyone, regardless of age or creed, to feel overwhelmed by the library­ of choice. Laptops, iPads, notebooks, Kindles, iPhones, netbooks, iPods and gaming consoles are all on offer under different brands and with varying specifications. This is failing to mention the infinite range of smartphones.

Exponential Times in the Information Age

*View this post in HD*

EXPONENTIAL TIMES: Extra! Extra! Etc. Etc.

I TREATED myself with a NAG (New Age Gaming) magazine the other day, which came with a glossy-ink-scented E3 (Electronic Entertainment Expo) supplement. The accompanying DVD was also largely dedicated to E3 and consisted of around two hundred game videos, trailers and GameTrailers.com awards.

I do not work for NAG nor do I sell their magazines. I was merely mesmerized by how far gaming has come in the last few years. We are certainly living in exponential times with the bacterial-like spread of information and new technologies.

Gone are the days of chalkboards and letter posting in the developed world. The sale and consumption of hard-copy books is fast dwindling at the hand of the Kindle and other eReaders. If Wikipedia were to be published as a book it would be over two million pages long. There are now even babies in the world named “Facebook.”

Exponential Times in Gaming
3D graphics has reached a point beyond comprehension five years ago. The number of gaming devices and vibrating motion controllers on the market this year can have one gleefully immersed 24/7 if you have the time. The exponential rate at which new game titles are being released has made the task of writing letters to Santa quite a meticulous one.

Exponential Times in Social Media
In 2007, one out of every eight U.S. couples met online. It is now estimated to be one in five. When television first entered our lives it took 13 years to reach a target audience of 50 million. Facebook took just two years to get the same number of people on board its platform.

Greater than the exponential development of technology, is the exponential availability of information. It is estimated that a week’s worth of the New York Times contains more information that anyone living in the 18th century would have consumed in their entire lifetime. The amount of technical information available is more than double every two years.

Exponential Times in Education and Employment
This exponential growth of technology and information is changing the way children are educated. Students are now being prepared for jobs that don’t yet exist and being trained to use technologies that have not yet materialised. It has also been shown that students who are online tend to outperform those who receive more face-to-face education.

This is of course changing the way that people are employed globally. It is estimated that 95% of companies that are online today recruit people using LinkedIn; around the same percentage of businesses use social media for marketing purposes.

Exponential Times Year to Year
In 2008, more than 200 million cell phone calls were made every second. This has roughly tripled every 6 months since. In 2009, every minute or so, a day’s worth of video footage was uploaded to YouTube. In 2010, the number of Google searches completed every ten minutes could have powered Las Vegas for half an hour. This year there are roughly 80 million Farmville farmers versus the 1.5 million real farmers. The moment you’ve finished reading this, most of this information will be outdated.

Below are two of the videos where you can find this information as well as more and more and more…

Whittle jet engine and how a plane flies

*View this post in HD*

FRANK WHITTLE: Genius inventor of the jet engine

IT’S quite amazing to consider that we are able to fly. We have built huge, metal birds they are able to take up to 800 people 11 000 metres above the ground without flapping their wings. Granted that aeroplanes are by no means perfect; but having achieved flight, and moreover being able to launch rockets into space, is certainly an achievement to be proud of. And it’s all thanks to the turbojet engine, or rather the man behind its invention.

Whenever one thinks of flight, the immediate names and imagery that might pop into one’s head are those of the Wright Brothers. Media coverage of such events, and consequently their recording into the history books, has a lot to do with that. History tends to neglect those without the proper status, family background or financial backing. In fact, the working class genius that thrust Britain firmly into the jet age was largely ignored by the British government and air ministry. They didn’t even bother to send a cameraman to the first (and successful) test flight of Britain’s first jet.

Frank Whittle (born 1907) is the genius to thank for our modern day aviation industry. Whittle began working as a fitter for the RAF (Royal Air Force) at the age of 16. Soon after he was air-born and performing stunt shows for the public. At 21 Whittle wrote a thesis titled Future Developments in Aircraft Design, in which he foresaw the entire future of flight. At 22, Whittle took out a patent for a jet turbine. He was also given a model aeroplane at age 4.

What made Frank Whittle’s jet engine unique is that it consisted of only one moving part – as opposed to the hundreds of moving parts used in conventional piston engines. Whittle’s piston-less jet engine also had no propeller, and drove planes through the air by thrust alone. Once patented and produced, Whittle’s remarkable engine successfully thrust Britain into the jet age and turned the aviation industry on its head.

How a jet engine works

The single moving part in a jet engine is the bladed turbine that spins at a remarkable speed and makes that familiar noise as a plane prepares for take-off. Air is sucked in and accelerated into large combustion chambers where fuel is injected and ignited. The ejection and burning of fuel heats and expands the air and gives it enough energy to drive the turbine. The turbine, in turn, accelerates the hot air at high ‘jet speed’ providing enough thrust to drive an aeroplane forward.

Actually getting into the air and staying there is all to do with working against opposing forces. It’s all a matter of lift versus weight and thrust versus drag. One also needs to consider the air as fluid – a sea of scattered water molecules that has density. In other words, an aeroplane sails across the sky rather than flies while a fish flies through the sea rather than swims. This is why it’s difficult to take off where the air is thin and why we should hope for a cold day whenever we fly.

It has to be said that Frank Whittle was a bit of an unapplauded genius. Being able to simplify a complex mechanism consisting of hundreds of moving parts into the single turbine jet engine, is nothing short of elegant. Being able to predict the next 50 years of an entire industry, is nothing short of visionary.
