I am trying to connect to a Galaxy Tab 10.1 running Android 3.2 I have seen several similar questions, but they all seemed to be related to having the device setup incorrectly. I have it set to allow "Unknown Sources" and I also have "Usb Debugging" enabled. I am able to use adb on both linux and windows machines so my tablet would seem to be correctly setup and the cable is functioning correctly. When I plug it in to my macbook pro the tab responds with a ping to show it is aware of the connection, but when I run adb devices no device is listed. My OSX install is fairly new and I have not

I've been trying to install Ruby on my Lion machine (OSX 10.7.3). I installed rbenv and ruby-build and am trying to get 1.9.2-p290 on my machine. Here is the output of the install failing: $ rbenv install 1.9.2-p290 Downloading http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz... Installing yaml-0.1.4...

I've installed postgres with the kyngchaos installer a couple of months ago. I've now updated to OSX Lion, but the database server fails to start. A comment on kyngchaos's blog ( http://www.kyngchaos.com/blog/2011/20110723_lion ) made me look at the 'postgres' user: it doesn't exist anymore! At least, I can't "sudo su postgres" anymore. So I figure that's the reason my server doesn't run. How can I best restore that user? (Answering myself) In the end, the only thing I needed to do was to re-create the "postgres" user. Beforehand, I listed the contents of /usr/local/pgsql/ and saw that for

I am using QTMovieView and , sometimes, I get the following log and follow by an unknown selector exception. The program has options for users to set to show and hide controller of the QTMovieView. The SDK that the program is linking against is 10.7 "[StdMovieUISliderCell sliderType]: unrecognized selector sent to instance" thanks for any help This looks like a bug that was introduced in OS X Mountain Lion 10.8 ( Edit: there are also reports on OS X 10.7, see comments below) . I guess that QTMovieView will get deprecated in one of the next major OS X releases. The best solution is to move to

Some C++ application compiled and run seamlessly in OS X Snow Leopard, but I changed recently to OS X Lion, and here, although there is no compilation error, when I try to run it I get the error "Illegal instruction: 4", I have no clue, what could be the reason? PS: These are the linking flags I use -Wl,-stack_size,0x10000000,-stack_addr,0xc0000000 This is the output I get when I do sudo truss executable setrlimit returned result = -1 SYSCALL(args) = return getpid(0x0, 0x0, 0x0) = 32993 0 __sysctl(0xBFFFF5EC, 0x3, 0xBFFFF5E8) = 0 0 issetugid(0xBFFFF5EC, 0x3, 0xBFFFF5E8) = 0 0 csops(0x0, 0x0,

I have a lua script, running on the Mac, that needs to call sudo. I'd hoped that Mac OS would automatically bring up a password request dialog, but instead it the command fails by returning 256. Is there anyway that I can achieve my goal? Tim Quick and easy way: run it like this /usr/bin/osascript -e 'do shell script "/path/to/myscript args 2>&1 etc" with administrator privileges' Proper and configurable way: use AuthorizationExecuteWithPrivileges API from Authorization Services (in Security.framework). Both will display standard Mac OS X GUI asking for administrator password and then execute

I use pygame for running experiments in cognitive science, and often I have heavy I/O demands so I like to fork off these tasks to separate processes (when using a multi-core machine) to improve performance of my code. However, I encountered a scenario where some code works on my colleague's linux machine (Ubuntu LTS), but not on my mac. Below is code representing a minimal reproducible example. My mac is a 2011 Macbook Air running 10.7.2 and using the default python 2.7.1. I tried both pygame as installed via pre-built binary , and I also then tried after installing both SDL and pygame from
