I'm trying to debug a segfault on an application I'm working on (works on linux of course, so I can't use that as my fallback for debugging core dumps). Anyhow, I've set "ulimit -c unlimited" and snow leopard reports "Segmentation fault (core dumped)" but alas there is no core file to be found. Does Snow Leopard put them somewhere spe...
Hi, I was reading your comment below: "I don't know what you mean by "power save" mode, but if you're thinking of when the screen is locked/off, that does not stop Core Location from running if your app is still running. On the contrary it's easy to run down your phone's battery much more quickly than you'd expect if you lock the phone...

Is there any possible way of disabling multi core functionality on windows and just using a single core using C\C++? Any library that allows it? My application access one of our chip modules used to communicate with the host. We suspect someone else is accessing this module and changes it. The strange thing is that it only happens on a m...
Hello, I am trying to convert Core Surface RGB frame buffer(Iphone) to ffmpeg Avfarme to encode into a movie file. But I am not getting the correct video output (video showing colors dazzling not the correct picture) I guess there is something wrong with converting from core surface frame buffer into AVFrame. Here is my code : Surfac...
I'm having an intermittent problem when I move a UIImageView around the screen using CAKeyframeAnimation. I want the position of the UIImageView to remain where the animation ends when it is done. This bug only happens for certain start and end points. When I use random points it works correctly most of the time, but about 5-15% of the t...
I've been using NSViewAnimation for some time now and I've read somewhere that Core Animation actually obsoletes it if I target 10.5 or higher. But does every Mac capable of running 10.5 or higher also support Core Animation? ...
I am trying to make a custom annotation view by subclassing MKAnnotationView and overriding the drawRect method. I want the view to be drawn offset from the annotation's position, somewhat like MKPinAnnotationView does it, so that the point of the pin is at the specified coordinates, rather than the middle of the pin. So I set the frame ...
In an interactive session like the following one: >>> f=open('test.txt','w') >>> f <open file 'test.txt', mode 'w' at 0x6e610> what does 0x6e610 represents and what could i do with that hexadecimal number in python? ...

On the iPhone, when you add a sub layer to a visible view's layer, using either -addSublayer: or -removeFromSuperlayer, shouldn't that sub layer appear or disappear in an animated manner (ie. fade in or fade out gradually)? My program animates using layers (not views). When I change a property of a layer like position or image content, t...
I've actually curious about this for the iPhone. I am getting an MJPEG stream from a server and trying to render it natively on the iphone (without the use of safari class). Reasons for this is because the safari class while CAN render MJPEG natively, does not do so at the framerate I would like. So I tried drawing it natively, but I've...
My app starts by presenting a tableview whose datasource is a Core Data SQLite store. When the app starts, a secondary thread with its own store controller and context is created to obtain updates from the web for data in the store. However, any resulting changes to the store are not notified to the fetchedresults controller (I presume b...
Hi all, A short but sweet question: Can I use Apple's open source Core Foundation (CF classes) in a commercial product for free? That is, can I compile and link against the libraries without open sourcing my own applications's code? Obviously if I alter the original CF code, I would submit the changes. It's a very well constructed AP...
My coworkers and I share an 8-core server running Ubuntu for our batch processes. I tend to run 4 processes at a time, each of which consumes 100% CPU per core when nothing else is running. When a coworker runs his processes (typically about 4 at a time), his also get 100% per. However, when both of us run ours (he always goes first),...
