multitasking

问题 Can two processes simultaneously run on one CPU core, which has hyper threading? I learn from the Internet. But, I do not see a clear straight answer. Edit: Thanks for discussion and sharing! My purse to post my question here is not to discuss about parallel computing. It will be too big to be discussed here. I just want to know if a multithread application can benefit more from hyper threading than a multi process application. After further reading, I have following as my learning notes. 1)

问题 iOS 9 introduced slide over and split view for iPad. How do I simulate these features on an iPad simulator? I have tried swiping from right on iPad Air 2 simulator with no luck. 回答1: To simulate slide over: drag from the right edge (starting from a point very close to the edge). To simulate split view: tap on the small white bar on the left edge of the slide-over app. See this WWDC video. EDIT (Thanks to @qix, @Bogdan Weidmann, @Solomon) Supported devices: iPad Air+, Mini 2+ for slide over

问题 I'm trying to mass encode video files in x265 and wanted to come up with a batch file that could automate the process. In order to expedite things, I found that having 3 instances of ffmpeg called with 2 threads resulted in ideal encoding times, however I've tried all day yesterday to come up with a way to get a batch file that will call 3 instances and then call new ones when they complete. So far, this is where I am: PARENT BATCH @echo off Setlocal EnableDelayedExpansion SET /A COUNT=0 for

问题 Yes, I know if I wish my app to be responsive to users' multitasking actions, such as switch to another app, I should deal with - (void)applicationWillResignActive:(UIApplication *)application - (void)applicationDidBecomeActive:(UIApplication *)application What if my app is doing a quite-long time consuming operation (like downloading a big file) and the user causes my app to enter the background? Will that operation automatically be suspended and resumed when the user comes back to my app?
