To help promote its Video Music Awards that aired last night, last week MTV employed a novel approach to aerial advertising. Instead of having a plane pulling a large banner, it used a pair of helicopters to create a flying movie theater that the Guinness Book of World Records has confirmed as the world’s largest aerial projection screen.
If you haven't learned anything interesting today, watch this fascinating history lesson on how the aspect ratios we know (16:9, 4:3) became the standard of what we see. For any film geek or ratio nerd, it's a lovely trip back into time where things can become standard by just doing it for a long time.
Probably the best wrinkle in aspect ratio history is how 16:9 came about: old 4:3 movie theaters birthed 4:3 television sets which stopped people from going to 4:3 movie theaters which made 4:3 movie theaters go widescreen to offer something different at home (which also eventually gave way to widescreen TVs).

The MacBook Air was the only new Apple hardware to be announced and launched at WWDC this year (besides the new AirPort Extreme), and while it isn’t a big change from the previous version, it packs some crucial improvements that really cater to the Air’s existing strengths. The 2013 Air is really Apple pushing the envelope with its ultraportable, and that has helped make one of the best computers in the world even better.
Apple hasn’t changed the MacBook Air’s physical design since its last major update a few years ago, but the sleek, aluminum chassis isn’t showing its age. Sure, thinner computers have emerged(though the Air is still thinner at its tapered end) but the fact that PC form factors are really only just now catching up speaks volumes to the quality of the Air’s industrial design.
Apart from overall good looks, the Air has a tremendous leg up on most computers in terms of size, weight and portability. If you haven’t yet used one for any sustained period of time, you’ll be absolutely blown away. Going from the 13-inch MacBook Pro to the 13-inch Air is like leaving the past behind and joining the future; big leaps in computing design are seldom so observable, and so noticeable in terms of your daily usage.
A concern with many who aren’t familiar with the Air is that the thin and light chassis won’t be durable, but having used both the 11- and 13-inch as my daily working computer for months at a time, while jumping from desks to various remote working locations, I can attest to those fears being unsubstantiated. The Air may not feel quite as rock solid as the 13-inch Retina MacBook Pro, for instance, but it isn’t fragile by any means.
Apple has improved the Air in key areas with this redesign, and that’s where it makes sense to focus, based on the understanding that the previous version was already one of our favourite computers. Apple has focused on changes that should have the biggest impact, like the new Intel Haswell processors, the much speedier flash storage, a near doubling of battery life, and networking speeds that embrace 802.11ac, a tech on the verge of becoming conspicuous in consumer goods.
Of these changes, the one with the greatest impact for the average user will be the new, all-day battery life afforded by the 12-hour capacity built-in pack on (on the 13-inch Air; the 11-inch also gets a boost, but should afford you 9 hours, not 12). Apple is also testing battery life under more demanding conditions now, which suggests that if people go to extreme measures to conserve juice they might be able to get past that 12 hour mark. And indeed, I was able to eke out around 13 hours at least once, with screen brightness dialed down and other battery drains like Bluetooth disabled.
The battery is truly remarkable. In standby mode, I haven’t yet even begun to scratch the surface of how long it can last after a week of usage. It really sips power when managing background tasks, and that should improve even further under OS X 10.9 Mavericks, which adds even more battery-conserving features to Apple’s desktop OS. The Air still ships with Mountain Lion, but you can bet Apple’s engineers were working on the upcoming OS X release when they were developing the new Air hardware.
Even without the extreme measures, this is a computer that you can forget is unplugged without fear of running into dire problems. If you’ve got a charge in the morning, and provided you aren’t doing anything too demanding that’s burning CPU cycles, you should have enough to get you through a reasonable mobile workday. Which is to say, we’re nearly at the point most people really badly want to be in terms of their MacBook’s battery life (short of limitless, endlessly clean and cool energy).
And the other upgrades help as well; the MacBook Air I reviewed was the 13-inch base model version, which retails for $1,099, but it come with double the internal storage standard vs. the 2012 model (128GB vs. 64GB), and Apple says that its new type of flash is a better performer, beating the previous generation’s storage performance speed by up to 45 percent. Certainly in testing the Air near-instantly recovered from sleep, and side-by-side with my top-end 2011 model, was snappier with nearly every task – likely also helped by the next-generation Intel Haswell processor.
Some nice new features on the MacBook Air that add to the computer in small ways are the addition of dual mics, which greatly improves call quality for things like FaceTime when you aren’t using headphones, and the new Intel HD Graphics 5000, which gives you around a 25 percent bump in performance over the Intel HD 4000 graphics chipset used in previous generations.
The other big new step-up in terms of features is the 802.11ac Wi-Fi networking card, which is complemented by the new AirPort Extreme router that offers the same. It’s a technology that’s becoming more and more commonly available on other routers, too, so it’s a very nice-to-have feature on the new Air, even if you can’t take advantage of it just yet. Still, in my brief tests with LAN performance over 802.11ac, I found that transfer times for files between computer and network-attached storage on the new router were just about halved vs. 802.11n speeds, though still lagged far behind wired Ethernet transfer times of course.
The new MacBook Air isn’t a dramatic change, but it is a very good one. I’ve fallen in love with Apple’s Retina displays, so if I have one complaint about the computer it’s that there’s no ultra-high resolution display, but incorporating that kind of screen in this generation would’ve likely meant trading a big chunk of that new battery life away, and also increasing the price tag by around $400-500. For those who value the portability, flexibility and economy of the Air above all, the 2013 edition definitely hits all the right notes.
Convincing kids to sit still long enough to take their picture either takes a small army of distracting stuffed animals, or the University of Tokyo's new high-speed camera tracking system which guarantees your subject is always in frame.
Instead of moving the glass elements in a lens, or the camera's sensor which can only compensate for subtle movements, the Ishikawa Oku Lab's system uses a pair of independent high-speed mirrors that bounce the subject into the camera's lens, while at all times compensating for extreme movements in pan and tilt. Seeing it action is utterly amazing, and there's no doubt this technology could revolutionize baby photography as we know it.
This version of London's iconic tube map looks just like the official PDF of the transport network—but in fact it is created entirely from HTML, CSS, and JavaScript.
That's a pretty insane feat. Its creator, freelance web developer John Galantini, has recreated every symbol, line, circle and piece of text using HTML and CSS. Each subway line is, in fact, an unordered list, with stations positioned in relation to each other using CSS. The map took 120 hours work over five weeks to complete. Pointless, perhaps—but nonetheless impressive. [John Galantini via Sidebar via Verge]
Customers with Sky Broadband might find their speeds begin to crawl northward towards the end of the year. The broadcaster is paying Virgin Media's business arm £49 million ($74 million) for some of Richard Branson Liberty Global's deliciously fast fibre infrastructure. While there's no mention of BT, we wouldn't be surprised if this technological makeover was wasn't prompted by its corporate rival's recent assault on Sky's sporty golden goose.
