  • 7 things you really ought to know about Apple’s iPhone 6

    In 2007, a Steve Jobs-led Apple announced "Project Purple," the codenamed operation that would eventually spawn the original iPhone. After its official launch a year later, the device became a mixed bag of sweet sales success and salty near-sighted design flaws. The world has since seen four additional iPhone models, with the sixth and most important version since coming later this year. Thanks to the usual barrage of Apple stories both fictitious and fact, we have a pretty fair idea of what to expect from Cupertino. Here's what consumers could, should and ought to expect from the firm's next super...

  • 6 petrol (and diesel) powered cars that’ll make you think twice about hybrids

    We've covered the flashy, footballer-friendly rides of World Cup stars, not to mention a gaggle of Formula 1 inspired vehicles for track day enthusiasts too, but what if style and speed aren't your prerequisites for a new car and fuel economy is? Currently hybrid cars win the battle between the pumps more often than not, but this doesn't necessarily mean all petroleum powered cars are slobs in comparison. In fact, some can challenge even the best hybrids on fuel efficiency numbers.

  • Ghana’s World Cup defeat to the US: the Twitter numbers

    Twitter is continuing its alternative coverage of the World Cup, this time dishing out metrics from the US and Ghana's (#GHAvsUSA) Group G clash, and Germany's 4-0 rampage of Portugal. Unfortunately for the Black Stars, the US ran out 2-1 victors against the run of play, thanks to an 86th minute winner from 21-year-old sensation John Brooks. With two goals in the final eight minutes of the match, it was one of the more exciting encounters in an already entertaining tournament. But how did the Twitter community react? 4.9 million total tweets for #GHAvsUSA According to the social network's analytics wizards, fewer...

  • Formula E is not the environmentally-friendly racing series we were hoping for, but it’s a start

    Let’s not fool ourselves. Although I hate to knock it before its first race, Formula E really is no greener than it’s petroleum-based cousins. The Formula E cars once racing will emit no carbon emissions, but that’s just on the track. The series’s trailer frustrates me the most. The stock footage of an unspoilt earth, people frolicking in fields and wind turbines gently twirling in the breeze suggests that Formula E is the motorsport that will change everything. If it is purporting to be a green series, its not only fooling itself but the public as well. Even though its...

  • 8 3D printed foods that will change the future of cuisine

    Like it or not, 3D printed food will be at the forefront of future cuisine. The technology to print edible foodstuffs practically on demand is around the corner, but the real issue for companies will be ridding 3D printed food of its unnatural, synthetic taboo. Food supply is a global issue and as the population continues to balloon, alternative resources must be found. 3D-printing provides a potential solution to the problems of food and time wastage, by producing 3D-printed food that one can enjoy practically immediately, without the added strain placed on the environment.

  • 6 terrible tech crowdfunding failures

    Crowdfunding has allowed developers and entrepreneurs an easier means of raising money while giving the public the power to influence their success. Great ideas are usually victims of absent capital, are able to germinate and mature while rewarding those who funded those ideas. It’s a self-sustaining ecosystem, and it’s brilliant — but only for good ideas. Often browsing through Kickstarter, Indiegogo and other crowdfunding platforms, one is greeted by completely unexplained, incomprehensible or utterly stupid concepts. Many of these fail due to a high funding goal, lack of publicity or a viciously competitive market. Others are just simply terrible. Read more...

  • The drive to perfection: a brief evolution of vehicle transmissions

    If there has been one area of car development that's undergone a massive tech explosion over the years, it's transmissions. Facing more recent pressure from lawmakers, the environment and the public than ever before, the past decade has seen automakers move away from fuel-drunk Earth-killers and towards smarter, greener and cleaner vehicles. Most are developing a form of hybrid power unit, meshing combustion engines with rechargeable electrical motors. Others like BMW, have invested heavily in lighter construction materials, shunning traditional alloys in favour of "carbon fibre and thermoplastic," in the case of its i8. But those not ready to...

  • Why Google Glass is destined to fail

    "Can technology be something that frees us up and keeps us in the moment, rather than taking us out of it? Can it help us look up and out at the world around us, and the people who share it with us?" These were questions posed by the new Google Glass chief Ivy Ross in an open Google Plus letter this past week. She however failed to answer them in the same breath, simply remarking that "no one has really tried to answer them with a product like this before." There are good reasons for this.

  • 7 of the best: Ayrton Senna’s most memorable Formula 1 drives

    Where there are great racing cars, like the McLaren MP4/4, there are usually great racing drivers sitting in the driver's seat. There were few greater in the modern era than Ayrton Senna. The late Brazilian is idolised in motorsport folklore and canonised in his homeland, lauded for his phenomenal talent, humble persona, ruthless determination and sheer desire to win. He won 41 races from 161 starts, taking 65 pole positions and earning three World Drivers' Championships. The San Marino GP, 20 years ago, marks the weekend that would change Formula 1 forever -- for the better and the worse. Read...

  • Lessons in the Streisand effect: SABC bans EFF ad as DA’s ‘Ayisafani’ gets half a million YouTube views

    The SABC has refused to air a TV advert from the Economic Freedom Fighter's (EFF) one of South Africa's youngest political parties. The ban, confirmed today by party leader and former ANC Youth League leader Julius Malema, comes just days after the Democratic Alliance's (DA) "Ayisafani" ad received the same blanket treatment. Both bans come just weeks before South Africa's national elections, scheduled for 7 May. The advert touches a few contentious political nerves, featuring photographs of the bloody Marikana massacre, where 34 miners were killed by police, and the recent Bekkersdal unrest in Gauteng. But perhaps the most provocative issue of...

  • Logitech Z200 review: stylish speakers, stifled sound

    I’ve been a happy Logitech customer for a while now. Seven years in fact. Its ever popular X-530s are still in my company, tickling my inner ears with its gorgeous sound delivery. But, the speakers are a hassle to keep organised. Some customers desire quality sound without the complications of a 5.1 setup. Essentially, a compact yet stylish pair of table toppers. This is where the company’s new entry-level Z200 comes into play. The tall, twin-driver desk-standing set is available in white or black with inverse accents.

  • 8 legendary, ludicrous and utterly lorn Formula 1 innovations

    Since as far back as the invention of the wheel, humans have felt the need to travel faster and faster, preferably in competition with someone else. In today’s world of Formula 1, this insatiable appetite melds both arcane methods of exploding fossil fuels, extraordinarily talented drivers and bleeding edge technology. Innovations are, and were never too far from the sport. That’s not to say all of these innovations were successful.

  • Windows update: Microsoft finally kills XP, refreshes 8.1

    Tomorrow is a much bigger day for Microsoft than many experts dare to admit. This month's edition of "Patch Tuesday" will see two important moves from Microsoft. Firstly, Redmond will shift the final security patches for Windows XP and Office 2003 before their developers move onto more meaningful endeavours. Secondly, and more crucially for those not living in the past, the long-awaited "Windows 8.1 Update" will arrive to users' universal chants of glee. Therefore Windows 8.1, at least in its current guise, will also face a type of symbolic defenestration. In addition to cumulative patches bundled alongside it, the Windows 8.1 Update...

  • 10 things we’re really going to miss about Windows XP

    On 8 April, Microsoft will finally cease support for its stalwart OS Windows XP. Released to manufacture back in August 2001, the company’s second most popular OS will be kicked out of Redmond well before its thirteenth birthday. But is this a premature move? Well, according to Net Market Share, XP is still used by a massive 29.5% of all PC users -- dwarfing Windows 8 and 8.1’s current share of 6.4% and 4.3%, respectively. This being said, in the natural lifecycle of OSs, support must come to an end sometime. Currently all XP users are greeted by this popup, warning them...
