Kids' iPad magazine Timbuktu rethinks in-app purchasing model
Timbuktu is an iPad magazine meant for children, and as our friends over at TechCrunch have noted, its developers recently rethought how it implements in-app purchases. The previous incarnation of Timbuktu (and most famously, Smurf Village, among others), made in-app purchases too tempting and easy for children. The result was high rates of in-app purchases, which was good for the company, but bad for parents who didn't approve of the large associated costs. Before, Timbuktu had little virtual bubbles that you "popped" to make an in-app purchase. The interface was clearly designed to pique childrens' interest, perhaps too much so. Now, Timbuktu has implemented a subscription plan, so that parents can buy lots of content all at once, and then kids can be free to discover it themselves without accidentally spending any money they're not supposed to. That definitely sounds more reasonable. It's worth noting that there are other ways to block in-app purchases. For example, Apple's Restrictions settings lets you to disable all in-app purchases entirely. Also, you can customize the amount of time iOS will require your Apple ID between successful App Store purchases. By default, it's set to 15 minutes. Keeping your children from spending too much on in-app purchases is an avoidable problem, and it's good to hear companies like the makers of Timbuktu are taking steps as well.
MIT engineers use ultrasound for improved topical drug administration (video)
Ultrasound is likely most often associated with sonograms, but some MIT engineers are poised to change that. By using two separate beams of inaudible sound waves (one at low-frequency, the other high) the team were able to increase the permeability of skin, in a bid to improve the efficiency of transdermal drug delivery. The technique works thanks to the waves exciting bubbles in a fluid (such as water), forcing them to swell and move chaotically. Once the bubbles reach a certain size they implode, sucking the surrounding fluid into the void. This process creates micro-jets of liquid, which cause miniscule tears in the skin, allowing it to (painlessly) absorb chemicals more effectively. In practice, a pre-treated area of skin is then covered with a patch containing the correct dose of drugs -- but don't worry, the skin is said to grow back just a few hours later. Up until now, research into ultrasonic administration of drugs has concentrated on low-frequency waves, because the higher end of the spectrum doesn't have enough energy to pop the bubbles. Higher frequencies do, however, help create more of them and also limits their lateral movement. By using both high- and low-frequencies, the MIT engineers found this produced better over all results, by not only increasing the skin's uptake of the medicine, but also increasing the number of drugs that can be delivered this way. With pretty much anything that is usually delivered in capsule form being on the cards, this could make the administration of many popular drugs much more convenient and / or effective. Also excellent news for those who really don't like needles.
Colloidal Display uses soap bubbles, ultrasonic waves to form a projection screen (hands-on video)
If you've ever been to an amusement park, you may have noticed ride designers using some non-traditional platforms as projection screens -- the most common example being a steady stream of artificial fog. Projecting onto transparent substances is a different story, however, which made this latest technique a bit baffling to say the least. Colloidal Display, developed by Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima, uses bubbles as an incredibly thin projection "screen," regulating the substance's properties, such as reflectance, using ultrasonic sound waves from a nearby speaker. The bubble liquid is made from a mixture of sugar, glycerin, soap, surfactant, water and milk, which the designers say is not easily popped. Still, during their SIGGRAPH demo, a motor dunked the wands in the solution and replaced the bubble every few seconds. A standard projector directed at the bubble creates an image, which appears to be floating in the air. And, because the bubbles are transparent, they can be stacked to simulate a 3D image. You can also use the same display to project completely different images that fade in and out of view depending on your angle relative to the bubble. There is a tremendous amount of distortion, however, because the screen used is a liquid that remains in a fluid state. Because of the requirement to constantly refresh the bubbles, and the unstable nature of the screen itself, the project, which is merely a proof of concept, wouldn't be implemented without significant modification. Ultimately, the designers hope to create a film that offers similar transparent properties but with a more solid, permanent composition. For now, you can sneak a peek of the first iteration in our hands-on video after the break.%Gallery-162176%
Spiritual Guidance: A first look at patch 4.1 for priests
Every week, WoW Insider brings you Spiritual Guidance for discipline, holy and shadow priests. Dawn Moore covers healing for discipline and holy priests, while her archenemy Fox Van Allen dabbles in shadow while knocking back "naptime potions." Dawn also writes for LearnToRaid.com and produces the Circle of Healing Podcast. Earlier this week Blizzard surprised the masses by releasing an early sneak peek at patch 4.1 on the PTR. Though the patch features no major raid content, it has made some tiny changes to the priest class that could have some big impacts! Among the patch changes for priests are a nerf to Power Word: Shield, a buff to Divine Aegis, a possibly nerf to Dispel Magic, and a new animation for Holy Word: Sanctuary which I've included a video of after the break.
The Queue: Better than Bejeweled
Welcome back to The Queue, WoW Insider's daily Q&A column where the WoW Insider team answers your questions about the World of Warcraft. Alex Ziebart will be your host today.Good afternoon, ladies and gents! Let's waste no time and jump right in today, shall we?Horris asked..."I have a question. What's with the sudden change from red to yellow sockets between T7 and T8 for warrior tanks?"Sockets have always been notorious for not being the optimal color for certain specs and classes. T7 seemed like the odd duck to me in that case, where the sockets were generally pretty good for most classes. Now they're back to being sort of weird like has almost always been the case.
Hunter pet tanks Heroic Sapphiron
Remember Durante of Hydraxis, who briefly became a hero among Hunter for tanking Gruul with his pet? Well, he's at it again with Bubbles the Gorilla still at his side. This time around his stalwart monkey took on Sapphiron, deep in the bowels of Naxxramas.In order to get the job done this time around, Durante mentions in his thread on the official forums that he had to do some pretty significant Stamina stacking, and his DPS was quite nearly nonexistant with the spec and equipment that allowed this to happen. He did just over 900 DPS over the course of the encounter. The raid didn't seem to need to stack any extra healers for this, but the five that were there had to be on top of their game. One attempt was cut short when Bubbles ate a pretty hefty crit, and pets can't be crit immune. Threat was a little dicey at first, Durante says, DPS really needed to hold back for awhile. They managed it though, and that's really all that counts.I wouldn't say that this is a sign of Hunter pets taking over as Tanks or anything like that, but it was probably incredibly fun for Durante and his guild. I have no idea where his guild (which is recruiting Healers, apparently) sits on the meter between "Casual" and "Hardcore" but even the most hardcore guilds need to have a little fun sometimes and I think this qualifies.
TUAW Exclusive: Nnooo's Pop for iPhone
Pop is a new game coming soon to the iPhone by a company called Nnooo, and TUAW got an exclusive look at the new app before the official announcement of the release later today. As you can see from the video preview above, it's a very simple, very casual game, but nevertheless offers some fun and quick touchscreen gameplay. Pop was originally released on WiiWare, the Nintendo Wii's downloadable content service, and I was wrong in the video -- there are no PC or Mac versions out currently, so the App Store is the second platform the game will appear on. I also show off a similar "game" called Bubbles, put together by Jesse Grosjean (maker of Taskpaper and Writeroom) for his three-year old daughter (I said six in the video, but she's younger than that). Pop runs with that idea of popping bubbles and turns it into a timed and scored game that turns out to be pretty fun. Click the link below to read more about Pop, including some features that aren't shown off in the video above. Update: Pop is now available on the App Store.
iPhone display "bubbles" causing toil and trouble?
Jockeys riding the Apple discussion forums are claiming that their iPhone displays are afflicted with tiny "bubbles." Apparently, the manufacturing issue is recognized by Apple who will replace the phone, no questions asked. So tell us dear readers, bubbles or no bubbles, what's your experience?[Via Textually]
