The next version of the iPhone OS has MT
Dunno when iPad will be on it.

I just saw that after I wrote that
Which of course had me drooling like a fan-boi for a bit.
When ssh, vpn, rdp, citrix, and vnc sessions stay connected, this thing turns into the ultimate wander-around the office console. |

It seems like the bad old days
Cooperative multi-tasking. Calls within the program to cause certain things to happen. But it also required you to code (damn, i forget the exact call) release() all the time, to tell the OS it was OK to task switch to anything else. By default, everything was critical code.
How is this different? |

Apple seems to know how to extend the OS over time.
They've moved through many CPUs and many OSes. They seem to know how to do the architecture so that they can swap out the hardware and so forth without the users noticing except for the faster speed.
Yeah, if it's cooperative multitasking initially, that's not ideal. But it'll probably work better on a locked-down platform like the iPad than it did in Win2.x Presumably, if someone writes an app that hogs the system, Apple won't let it through. Supposedly, future versions of the iPod and iPad will have the ARM Cortex 9 dual-core chips, so they'll have the hardware for more advanced schedulers, etc. Apparently, it's not so much "cooperative multitasking" as limited exposure of system multitasking services - http://www.tech-news...multitasking.html FWIW. Cheers, Scott. |
