It’s truly remarkable to see almost every trace of a successful, well-established Valley start-up’s work wiped out in the span of 24 hours, but here we are: T-Mobile’s discontinuing the Sidekick line as of tomorrow, July 2, which effectively means that the Sidekick LX 2009 will no longer be available. As a refresher, the latest Sidekick LX was the last product holistically engineered by Danger as it got shoehorned into Microsoft — square peg in a round hole, as it were — before repurposing the team to work on the just-killed Kin line. In a way, it’s a miracle that the LX ever went back on sale following the nightmarish data issues they’d gone through last year, so we suppose it’s a silver lining that they made it this far — but still, it’s sad to see Danger’s years of design effectively vaporized without a trace like this. For what it’s worth, T-Mobile says that it’s working “on the next chapter of [its] storied Sidekick franchise” and to “stay tuned” for a “fresh” experience, but since T-Mobile owns the Sidekick brand (not Danger / Microsoft), we’ve got every reason to believe these new products will be based on Android considering the carrier’s huge investment in its myTouch line. Adios, Sidekick — we’ll do one last screen flip in your honor.
Dell’s updated Inspiron series has a few new design tweaks and a wide variety of configurations to choose from. We’ve reviewed two models from the series to see what’s new.
Coming up with a significantly new approach for generating colors in a projector isn’t easy. Neither is coming up with a new approach for generating the light itself. That makes it a big deal that Casio’s managed to do both at once in its Green Slim projectors, with its new Green Slim hybrid light source.
Projector manufacturers all know the harmony to “It’s not easy being green,” because projectors generally are pretty much the opposite of green. The central problem is the standard projector lamp, which eats up lots of power, wastes lots of energy as heat, and includes mercury as one of its components. A few projectors today use LEDs or lasers instead of a standard lamp, but most of those are either pico or palm-top projectors that offer a relatively dim 100 lumens or less. I’ve yet to see any that offer more than 1000 lumens.
Casio’s innovation is to combine LEDs, lasers, and phosphor. The combination lets its Green Slim projectors reach 2000 to 2500 lumens depending on the model, a brightness level that puts them in the same category as traditional projectors aimed at small conference rooms and portable use.
The Arduino microcontroller: fuel for so many delightfully geeky projects. Your wacky instruments and DIY ‘less lethal’ weapons will be getting a lot ‘looser’ soon, thanks to Seeed Studio and it’s Arduino compatible flexible printed circuit (FPC) board. Unlike most circuit boards, the insulating material in an FPC is — wait for it — flexible (hence the name). Featuring a fully functional Atmega 168 / 328 breakout, USB-Serial interface, a built-in charger circuit, and more, the Seeeduino Film only exists in prototype form at the moment. That said, the company said that it is making several units available “for community inspiration.” Hop on over to the source link to get in on the ground floor.
According to a video posted by the National Defense Education Program, the U.S. Air Force special operations division is the driving force behind a fascinating new invention. The Remote Auxiliary Power System is designed to enable soldiers to charge electronic devices in the field. This isn’t a ruggedized battery system though, but rather a device that allows soldiers to get the juice they need directly from power lines — no outlet required!
To use the RAPS, a soldier simply tosses it over a power line, and the cutout on the peripheral locks it in place over the line. A small razor blade actually pierces the power line, and a built-in transformer steps the power down to a manageable level in order to power and/or recharge any electronic devices necessary in the field.
The device is still being developed, but extensive safety testing is already underway. One question that has been answered so far: the RAPS system has been so carefully designed that it is actually safe to use when it’s raining.
DirecTV and Panasonic flipped the switch on the nation’s first 24 hour 3D network this morning, sending n3D out on channel 103 to all properly equipped viewers. Of course, if you’ve got your 3DTV, your H21 or higher satellite receiver and some 3D specs, what will you be watching? Besides events like the upcoming NASCAR race from Daytona, an exclusive 3D feed of the MLB All-Star Game and (locally available) broadcasts of a Yankees/Mariners series, July’s schedule is packed with demo content like Guitar Center Sessions with Peter Gabriel and Jane’s Addiction and Dinosaurs: Giants of Patagonia. Beyond that there’s a few IMAX flicks on the new DirecTV Cinema in 3D channel, and World Cup games from ESPN 3D through video on demand, check Zap2it for a full schedule but don’t be shocked to see a lot of repeats, for now.
Still haven’t received your HTC Droid Incredible due to that AMOLED shortage? Then it looks like you’ll soon be hearing from Verizon, if you haven’t already. Android Central reports that the carrier has begun sending letters to all customers still waiting for their phones that apologizes for delay, and informs them that they’ll soon also be receiving a $25 Verizon gift card as a little thank you for their patience. As for when you’ll actually receive the phone itself, however, Verizon is only saying that if your order date was June 28th or prior, you “may experience an additional delay of up to 7 business days.”
Microsoft has certainly had some ups and downs with its products over the years, but we’re pretty sure the company’s new InstaLoad technology falls somewhere between a home run and the best thing it’s ever done. It promises to do nothing short of redefine the way you insert batteries, and let you shove ’em into devices without any regard for positive or negative polarity. That’s apparently possible thanks to a patented battery contact design, which Microsoft says “simply works,” and is compatible with a whole range of battery sizes (both standard and rechargeable). What’s more, Microsoft is now already licensing the technology to third party device suppliers, and is even offering a royalty-free license for suppliers and manufacturers of accessibility products. Still no word on when the first devices using the technology will be available, but Microsoft already counts Duracell and flashlight-manufacturer AE Light among its partners. Head on past the break for the complete press release.
The major new feature of Apple’s latest mobile operating system, iOS 4, is multitasking. What took the company so long? Apple claims it was waiting to get multitasking just right before unleashing the feature for the iPhone. Meanwhile, the Android OS and Palm Web OS have supported multitasking just fine for over a year.
However, each platform handles multitasking quite differently. Let’s take a closer look at how each mobile OS’s multitasking works.
Apple iOS 4
How you use it When you press the Home button twice, Apple’s iOS 4 displays a “drawer” allowing you to switch between apps. The drawer shows your most recently used apps. This is similar to the “alt-tab” functionality we’re accustomed to on traditional PCs.
What’s going on When you leave an app in iOS 4, it’s not actually closing (unlike previous versions of the OS). Instead, it’s going into frozen, suspended animation, sitting inertly in the background. So when you relaunch an app, it opens instantly to pick up from where it left off before you “closed” it. That behavior allows you to switch between apps very quickly — a feature called Fast App Switching, which is the core functionality of Apple’s iOS multitasking. (TidBITS has an excellent in-depth explanation of Fast App Switching.)
Fast App Switching isn’t all iOS 4 multitasking does, as there are a few exceptions for specific types of apps. Apple allows apps that play audio, connect with voice-over-IP or use location detection to run quietly in the background while one thread is still active. So that’s why, for example, you can leave the Pandora app, and the music will still be playing in the background while you check your e-mail. Likewise, you can leave Skype while on a VoIP call, and you won’t hang up on your buddy while you’re browsing Safari, for example. Third, you can leave a mapping app or a fitness tracker like RunKepper and come back to it, and it’ll still have a lock on your location.
It’s up to third-party app developers, of course, to tell their apps to behave this way with the new iOS 4 software development kit.
Another sort of background activity iOS supports is push notifications, which keeps a specific internet port active while the iPhone is in hibernation, so you can receive e-mails, instant messages and alerts even when the screen is off. These alerts pop up on the screen in the same way as SMS on the iPhone.
WIRED Fast App Switching is indeed fast and stylish, avoids draining battery. All apps are constantly running inertly, so you can quickly switch between them all.
TIRED Only allows a single application thread to continue running; only certain kinds of activities are allowed to run in the background. Push notifications scream for your attention at the center of the screen.
Android OS
How you use it Hold down the Home button and a tray appears showing the apps running in the background. Switch to another app and it instantly opens.
What’s going on Android’s multitasking behavior is by far the most complicated to explain.
In Android, when a user switches to another application, the app you switched from doesn’t shut down: Its process is kept around in the background, allowing it to continue working (e.g., for downloading web pages in the background while doing something else), and come immediately to the foreground if the user returns to it. If the smartphone is running low on memory, Android starts killing off unnecessary processes to free up resources.
If a user later returns to an application that’s been killed, Android re-launches it in the same state as it was last seen, by keeping track of the parts of the application the user is aware of, and restarting them in the last state they were seen in. This last state is generated each time the user rotates the screen or leaves the application.
There are two basic components to control what apps can do in the background. Apps with “broadcast receivers” go into the background and wait to go off in an event, such as an alarm going off at a certain time, or if you receive a notification from Google’s server for getting a new message in Gmail. The other background component is called a “service,” which instructs an app to perform a task such as music playback or turn-by-turn navigation for a certain amount of time in the background. It’s up to the third-party app developers to embed these components in their apps so they behave these ways in the background.
WIRED Apps can stay fully functional while running in the background. Notification tray makes it easy for apps to give you information without interrupting what you’re doing. Users don’t have to manually quit apps when memory is running low: Android does that for you.
TIRED Getting multitasking to work just right in an app is a lot of work for developers.
HP WebOS
How you use it The HP (formerly Palm) WebOS displays apps as “cards.” Each card acts similar to a tab in a desktop web browser. You move between activities using gestures (swipe forward, swipe back, hold to readjust the positioning of the cards), and when you’re finished with an activity, you can throw the card off the screen to quit the application.
What’s going on WebOS allocates resources (memory, processor cycles, network access) to each card based on requests from the cards. The System Manager prioritizes the card in the foreground when allocating resources. Apps in the background are placed in a semi-dormant state, and their access to services is restricted.
If an application that the user isn’t currently interacting with wants to get the user’s attention, the app can display information in the notification area at the bottom of the screen. The information sits in the dashboard until acted on or closed. (Therefore, you can do something in a foreground app while dealing with a notification, whereas on the iPhone a push notification shows up in the center of the screen interrupting your task until you close it or leave your current app.)
Activities in the background do not have access to certain battery-intensive services. For example, apps cannot access accelerometer data and their frequency of network access is reduced. Third-party games are paused in place when moved to the background, reducing both their CPU load and memory consumption.
WIRED The card interface is neat, and it feels very natural to switch between apps. Notifications appear at bottom of the screen, not interrupting your current task.
TIRED After launching a specific number of apps that reach your memory limit, you can’t launch any more, and you have to manually quit an app before launching another.
The Toshiba Libretto W100 made a guest appearance on the Engadget Show last week, and since we got to spend a bit more time with the dualscreen laptop we thought it was only right to release some more impressions into the ether. We also got confirmation from Toshiba that the somewhat-of-a-concept-PC will be hitting retail channels in August, including Amazon, and will cost $1,100. It may be one of the only dualscreen tablets on the market, but no matter how you break it down that price seems a little outrageous. But you wouldn’t make up your mind before reading some further impressions and watching a close up video of the screens working in tandem, would you? Well then, we’ll see you after the break.
