How Does 3D Technology Work?

In 1838, Sir Charles Wheatstone first described the process of stereopsis: the process by which humans perceive three dimensions from two highly similar, overlaid images. Or, the process by which Avatar looks like a mind-blowingly immersive alien landscape instead of a bunch of brightly colored fuzz. 3D technology has come a long way since Wheatstone developed his stereoscope, then used to view static images and eventually pictures. Now we get to wear Wayfarer knock-offs and enjoy 3D films, television shows and video games. For some people, seeing cool images might be enough. But others might be curious how Pandora was brought to life, or how...

How Africa’s economy is benefiting from the ICT revolution

Standard Bank analyst Simon Freemantle recently produced a series of five research papers on the trends powering Africa’s economic growth. During the course of the week, How we made it in Africa will examine each of these five trends in more detail. In our third article, we look at the economic effects of Africa’s ICT revolution. Africa’s ICT revolution has been well-documented in this publication and others. In 2000 there were only 15 million mobile subscriptions on the continent, by 2010 there were believed to be in excess of 500 million.

Breaking News: Facebook Initial Public Offering (IPO)

Facebook is preparing to go public in the biggest tech IPO since Google. But what does that mean for its users – and its rivals? Any day now, perhaps as early as Wednesday, Facebook will announce it is going public. The firm is looking to raise $10bn selling shares in an initial public offering (IPO) that will value the firm at somewhere between $75bn-$100bn, according to reports. Not bad for a seven-year-old firm that has only recently started making money and apparently made $1bn last year. It will be the biggest tech IPO since Google, and investors (and rivals) will finally get to see what makes Mark Zuckerberg's social network. Is Facebook...

The Days of "Manager Knows Best" Are Ending

To get a glimpse of what tomorrow's young global managers might be like as leaders, take a look at how today's young people think about communications. For one thing, they are devoted to connectivity. In a recent survey of more than 2,800 college students and young professionals in 14 countries, Cisco found that more than half said they could not live without the internet, and if forced to choose, two-thirds would opt to have an internet rather than a car. This intense desire to be connected leads to a demand for greater flexibility: Two out of five people said they'd accept a lower-paying job if the position offered greater flexibility on access to social media, the ability to work from where they chose, and choice on the mobile devices they could use on the job. Tomorrow's young managers...

Is it better to turn my computer off or leave it on all the time?

This is one of those questions where there is no single right answer. In other words, it depends on how you use your computer. There are at least three situations that force you to leave your computer on 24 hours a day: You are on a network, and the network administrators back up files and/or upgrade software over the network at night. If that is the case, and you want your machine backed up or upgraded, then you need to leave it on all the time. You are using your machine as some sort of server. If you are running something like SETI@home and you want to produce as many result sets as possible, you need to leave your machine on all the time. If...

New Samsung Galaxy 10.1. Expert Review

The Samsung Galaxy Tab is the first major tablet release since the Apple iPad launched about five months ago. It's been a long time coming, too. The Galaxy Tab was one of the all-time worst kept secrets in tech until it was finally unveiled at Berlin's IFA show back in September, and as the first major Android tablet release, it holds a weight of responsibility on its shoulders. With a tidal wave of Android tablets about to sweep through the tech world, it's possible that if the Galaxy Tab were to disappoint, it could damage the perception that Android tablets will be able to top the iPad on features and performance. The price certainly indicates...

Agriculture : How Can Information Technology Be Used

Getting the right information to farmers, when and where they need it, in a form (language and tone) they understand and can easily access is as vital to the success of the agriculture sector as the right type of soil, adequate water, sunlight and any other input. For this primary reason, I endorse BIID's call for information to be considered as an input in agriculture. It holds true beyond the Bangladeshi context. A lot can be learnt from this report from India in this video It is mind-boggling to me that so few countries in Africa, the Caribbean and Pacific, where agriculture remains a key employer and contributor to national income, have...
