Windows Since I'm a little under the weather at the moment, posting is a bit slow on OSNews (yes, a story about Notion Ink's Adam is upcoming!). I'm kind of picking the simple and easy-to-write items for now, and this is most certainly one of them. As some of you might know, Microsoft unveiled Windows Phone 7 Series yesterday, a complete reboot of its mobile operating system. While little is known about its internals, it's most likely based on Windows Embedded CE 6.0.

The WebOS problem you use as an example is, well, a WebOS problem. It's a fairly new operating system and its multi tasking implementation is not as good.

webOS is a standard Linux OS with a proprietary GUI slapped on top of it. There it nothing new about its multitasking capabilities.
Are you sure you are a "professional" on that field when you don't even know such basic things?

Err, it might be Linux underneath, but webOS has a completely custom userland - heck, it has a very revolutionary userland. It's not just a reimplementation of some existing idea - it's completely new.

As such, it is to be expected that the webOS' multitasking capabilities need refining.

Since when does the userland handle multitasking?

Oh, and BTW: webOS's userland is far from being totally new. If you look at http://opensource.palm.com/1.3.5.2/index.html you'll see many familiar packages (at least familiar to people with some Linux knowledge)

An operating system is more than the just the kernel; an operating system is made up of many components and just because it uses a component from few open source projects doesn't change the fact that it is more or less a new operating system. New doesn't have to mean "from the ground up".

The original postered pointed out that it is a new operating system because many of these components aren't full optimised for the constrained environment - thus there has been severeal releases so far fine tuning different parts of the operating system to make battery life better, multi-tasking smoother and so on.

The way you're behaving sounds like you're accusing Palm of simply grabbing some soruce code, compiling it and then throwing it on a telephone and hoping for the best.

Don't put words into my mouth! I never wrote that. Go trolling somewhere else!

It doesn't sound like they used a Linux-variant that is actually tuned for embedded use. But more of a general purpose one, normally used for desktops or maybe even servers.

What do you think "tuned for embedded use" even means?
Linux kernels for embedded systems are not total rewrites. Embedded developer Monta Vista does all its work upstream in the Linux kernel -- Monta Vista is one of the biggest kernel contributors.
It's not rocket science to turn off features that are not needed on phones, just as it's not rocket science to turn on or tweak other options.
