Wisdom through Knowledge

Knowledge is where you find it; it manifests as information all around us. Art is where you experience it; it exists in grains of sand and in clusters of galaxies. Sometimes the lines between the two is unclear. They are both ways of understanding the world around us. We see them in the form of technology, writing, programming, drawing, photography, among other means of expression. In this blog I share these expressions as I live life and experience it. I am Suleman and this is my blog.

Matlab and OS X Mountain Lion (10.8)

A little background

The current latest version of Matlab is 2012a. It was released for Mac OS X Lion (10.7) so requires X11 to provide the GUI. However, with the release of Mac OS X Mountain Lion (10.8), X11 is no longer provided by default from Apple. This poses a bit of a problem for Matlab 2012a.

What to do with Matlab 2012a on Mountain Lion?

While Mountain Lion doesn't have X11 and Apple isn't providing their version of X11, they are providing development support to the Open Source project that the Apple X11 was based off of: XQuartz.

Issue with 32-bit Applications on 64-bit Linux

When running 32-bit applications on 64-bit Linux you may find that your application does not run and gives the following error (or similar):

GLib-WARNING : getpwuid_r(): failed due to unknown user id

This error was noticed when running 32-bit SPSS on 64-bit RHEL 6 with LDAP authentication. The reason for the issue was the lack of 32-bit versions of sssd; 32-bit applications cannot use the 64-bit versions of the libraries and hence SPSS could not lookup the appropriate user information.

The correct resolution for this is to install the 32-bit version of sssd (in addition to the 64-bit versions) so that the 32-bit versions of pam_sss and nss_sss are available for use by 32-bit applications.
