Yay!!!!! Thank you! Thank you!

Well I see no reason why not. all DGOS apps should handle that just fine. As for palmos compatibility layer - I am not sure, but I think something can be done to make that possible too.

To elaborate on that: my idea was to extend palmos layer with some useful functionality for devs who prefer that environment. The extensions i was thinking of were just two:

-allowing native arm apps
-allowing multithreading

Multithreading? Do you think multithreading is efficient on a single CPU? Or you are planning to extend that to the wifi chip?

Surely you've heard of Linux, Windows, MacOS, Unix? They all do multithreading on a single cpu...

I think he meant multi-threading as in more than one thread running at once, which isn't anyway possible on a single core cpu. Either that or two threads for one program which can result in inefficiencies.

Yeah, I've heard these names, but can't remember where and who has mentioned them

I can see the only advantage in using threads (OpenMP or Pthreads) on a single CPU in asynchronous event handling/scheduling. Is that what you meant? Otherwise it only slows down the program due to the threading overhead, as I think

Pgr My T\|X loves this site! Join Date: Feb 2007 Posts: 613	Threads and tasks aren't that different, and both multitasking and multithreading are possible on single CPU's. Of course, you have to understand that on a single CPU things aren't happening strictly at the same time, but as far as the programmer is concerned, they are, since the OS takes care of timeslicing the CPU so that the appearance of multiple execution occurs. This effect is much more important to computer science (it's a powerful new model) than the subsequent application of multi-core processors or multiprocessors (which basically only adds to the efficiency of execution). DGOS will be able to multitask and to multithread, because it is being written in the 21st century by a person who is not an idiot. It won't require multiple cores or processors to do this. PS - the difference between threads and tasks (or processes) is that a task can subdivide in multiple courses of execution called threads. The main difference in handling these is related to memory isolation (tasks are not supposed to see or change other tasks' memory, threads often need to share memory with other threads of their own task, because they were written by the same developer, and are working on the same thing). In Windows NT/2k/XP/Vista/7 (and possibly in other OS's, I don't know) the sheduler only schedules threads, it doesn't really bother which process they belong to. That only becomes relevant in issues of memory sharing and synchronization. I hope this helps, or maybe I've just left you all more ... __________________ Publish eBook - Convert structured Word Documents to eBooks with just one click. Free to download and use!

I would love to see DGOS for my TX and/or Centro - I love Palm apps because they are fast and do what I need them to do but I miss some of the stuff which is not supported on Palm: - international characters support (Latin-2 for example) - multitasking - stable and better browser Having bought few Dmitry's apps I believe he can do it (if he wants to) so I am waiting.
