I have already upgraded to Python 2.7.6 RC1. Also happened in 2.7.5, also happens outside ipython. What am I to do? This appears to be a bug in Numpy that has been fixed recently.

I want to write a usb touchscreen kext for usb touch screen . I have read the Kernel Extension Programming Topics and the I/O Kit Fundamentals etc, My question is, 1 . how to get the input report messages from touch screen ? 2 . how to post the coordinate info to system ? I have no idea, anybody help? It depends on the hardware; moreover, this question is quite broad - you'll need to be more specific in your question to get more specific answers. I'll try to provide a broad overview: A touchscreen has 2 parts: Output: showing the image coming from the computer on the display Input: the touch

I've ready through other threads on Stack Overflow and despite my efforts the issue doesn't seem to resolve. Since installing OS X Mavericks I'm not able to open Sublime Text 2 from the command line. I've tried following these guidelines: http://benkwok.wordpress.com/2013/11/17/setup-sublime-text-2-on-osx-mavericks-for-ruby-on-rails/ When I run this from the terminal Sublime pops up so that's good: http://benkwok.wordpress.com/2013/11/17/setup-sublime-text-2-on-osx-mavericks-for-ruby-on-rails/ I've added these lines to the bottom of my bash_profile: export PATH=/bin:/sbin:/usr/bin:/usr/local

I have the following simple program involving pthread and semaphore. I am in osx Maverck 10.9. I use a makefile to compile the program (rather than xcode). I use c++11. #include <pthread.h> #include <semaphore.h> #include <cassert> #include <iostream> #define ASSERT(a) if(!(a)) abort using namespace std; sem_t countMutex; int myCount=0; void *doThread(void *data) { int *pi = reinterpret_cast<int *>(data); sem_wait(&countMutex); for(int i =0 ;i < 100; ++i) { myCount += 1; } sem_post(&countMutex); pthread_exit( NULL ); } void LaunchThread() { const int kNumThreads = 10; pthread_t tids

Is there a recommended way for CBPeripheralManager to terminate a connection. The best way I have found so far is simply not to respond to dynamic value, then the BLE stack seems to close the connection, but that seems rather crude. There must be a better way? No, you can't forcefully close a connection in a clear way from the peripheral side. There is no API for it. You can break the connection abruptly by not responding to a request, which results in disconnection at most after 30 seconds. This is the standard behavior defined by the Bluetooth specification Vol.3 Part F 3.3.3 A transaction
