A Closer Look at Classic on the Palm Pre

With the Palm Pre hauling a brand new OS in tow, a surprising number of long-time Palm fans have come out of the woodworks to express their desire for legacy application support. At CTIA09, Palm and MotionApps answered these calls with the annoucement of Classic, a PalmOS emulator for the Pre's nascent platform, webOS.

The first half of the video clearly demonstrates that the basic functionality of the emulator is in place: the virtual 5-way key works as expected, with simple applications (such as Tasks and Agendus) ticking away without a hitch. But what about apps that are a bit more resource-intensive?

To think that an application from years ago might not run properly on a device of today's hardware standards may seem crazy, but it's a common obstacle of emulation. When you're taking something physical (the original hardware) and turning it into something virtual (the emulation software), a ton of translation has to be done on the fly. This generally makes the emulated system require far more resources than what it was composed of originally. Ever wonder why we rarely see emulators for gaming consoles until years after the console's release? That's a big chunk of the reason why.
Though one could see an icon for PopCap's Bejeweled floating around in our initial demo footage of Classic, it wasn't being demonstrated that day. Bejeweled isn't the most visually complex game ever, but it's a bit flashier than the text-centric Apps they had on display - why not show it off, instead? Could Classic handle rich graphics?

Looks like it. In this video, MotionApps skips right past the simplicities of Bejeweled and loads up GTS: World Racing, a relatively complex 3D racing game. Though the demonstrator doesn't have much luck handling the car, Classic seems to have no problem handling the game. And unless that engine whine we hear as the car breaks away from the starting line, this video confirms support for audio support in applications, as well.

MotionApps has also just posted a Q&A on Classic which clears up a number of other matters.

Here's what we can glean from the post:

Classic can only emulate screen sizes up to 320×320. (Treo and Centro apps are fine - but apps specific to 320×480 devices such as the Palm Tungsten or T|X are not.)MotionApps is staying out of the matter of licensing. If an app's license says you may only install it on one device and you install it anyways, that's your doing.webOS only allows one instance of an application to be open at a time - if you try to launch a second instance, it'll just bring the first one to focus.Classic can run native 68k/ARM codeThough the Pre doesn't have an SD card slot, Classic wills simulate an SD card with a dedicated folder on the device's filesystemNo HotSync support, but you can configure your HotSync ID for applications that require it.WebOS PIMs (contacts, calendars, tasks and memos) can not be accessed.Classic can not access Bluetooth, the phone radio, GPS, light sensors, camera, or the accelerometer.PalmOS apps that require net connectivity will function properlyThe PalmOS browser, Blazer, has been disabled. Browser requests will instead be sent to the webOS browser.

Last fall, the Woodbine, Md., mother of three figured out a great way to get some: online giveaways. She has entered about 40 so far. She has won T-shirts, cleaning products, a small portable vacuum, olive oil, beef jerky and -- best of all -- a Nintendo DS on Web sites such as, and

"The lure of free stuff is quite appealing," she said. "I never considered myself a winner. I don't think I ever won bingo. My name was never drawn from a hat. However, I've been extraordinarily successful at the giveaways."

The recession has emboldened a certain kind of consumer: The mooch. With dwindling retirement savings, a higher cost of living and wobbly job market, they don't just want discounts on items they used to pay full price for without a second thought. They want freebi…


A RECENT NOR EASTER HIT THE NEW ENGLAND COAST AND AS THOUGHT THIS WRECK SURFACED AGAIN FROM ITS BURIED DEMISE--The skeleton only appears periodically - the last time was in 2013 - always after a significant coastal storm, and always attracting attention. Archaeological work conducted in 1980 indicated the wreck is a sloop of about Revolutionary War age. It is likely a “pinky,” a type of vessel with a high, narrow stern and square rigging easily maneuverable along the coast of Maine. Pinkies were popular as fishing and cargo vessels. The first sighting of the skeleton was in 1958, and then it has surfaced periodically right up to the present day - and usually after a good spring nor’easter. Word spread quickly about this sighting via social media, and people came over the weekend and on Monday as well. First, they had to navigate the seaweed- and rock-strewn streets of York Beach. They were also precluded from parking cars in most of the Ellis Park lot, which was buried under a layer …


I've always felt a special fascination for mosaics. From Roman tile compositions to current digital collages, I think they're an awesome artistic expression.
That's why I was so happy when I found Andreamosaic.
This tool enables you to create amazing mosaics from your digital pictures in a very easy way.
It requires having a large collection of photos to use as tiles, that's true. Fortunately the installation file already includes a pack of 500 sample photos that produce excellent results.
The program's interface is quite dull; in fact it's simply a gray window with too much text on it. But the mechanics are easy to understand so you'll be creating your own mosaics in no time!
Plus, the program includes a 20-page manual that explains everything thoroughly. Just remember that the more tiles you use, the longer it will take to generate the mosaic and the larger the final file will be.
