When trying to get local data to Heroku, I am encountering a version mismatch between two different versions of pg_dump. Specifically, I am getting this message: pg_dump: server version: 9.2.2; pg_dump version: 9.1.4 pg_dump: aborting because of server version mismatch I have found others with this problem, but do not know enough to implement the proposed solutions. (I am new to Ruby on Rails, PostgreSQL, Heroku, and the Mac! Very much at the stage of playing around the picking things up as I go.) I was thinking I might simplify my life if I uninstalled all PostgreSQL on my local machine and

After update to Mountain Lion, I tried install 1.8.7, and I got error. X11 file not found, I installed Xquarkz, but nothing changed. Whats wrong?

Is it possible to use GLUT on OS X Lion or OS X Mountain Lion using core profile (so I can use GLSL 1.50)? Can I use the built in GLUT or do I need to use a third-part library such as FreeGLUT? And is there any simple 'Hello world' applications available for OS X with either an XCode project or a make-file? You need at least Mac OS X Lion (OS X 10.7 or higher) for the basic support of OpenGL 3.2. To use the OpenGL 3.2 Core Profile, just add glutInitDisplayMode(GLUT_3_2_CORE_PROFILE | ... | ...); in your main -function. You can check it by std::printf("%s\n%s\n", glGetString(GL_RENDERER), // e

I am trying to instal virtualenv and/or virtualenvwrapper on a mac osx 10.8.3 I have been fighting with python for the last two days. Finally I was able to install python 2.7.4 using brew. Before I had virtualenv installed using easy_install. Then I tried to uninstall it, trying to get my computer in the same situation as the one of my colleagues. Maybe I uninstalled it with success, maybe not. I don't know how to test it. Now I am supposed to install virtualenv using - pip install virtualenv But it gives me - Could not find an activated virtualenv (required). pip install virtualenvwrapper

Can someone give an example of sending a test notification from a Cocoa app to Notifications Center? eg. when I click on an NSButton alexjohnj Notifications in Mountain Lion are handled by two classes. NSUserNotification and NSUserNotificationCenter . NSUserNotification is your actual notification, it has a title, a message etc. that can be set via properties. To deliver a notification that you've created, you can use the deliverNotification: method available in NSUserNotificationCenter. The Apple docs have detailed information on NSUserNotification & NSUserNotificationCenter but the basic
