I updated my computer today and it seemed to break Skype for me.  Every time I would try to load it from the command line I would get the error

skype: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64

This problem on 64-bits systems is caused by /usr/lib being earlier in the LD_LIBRARY_PATH than /usr/lib32. Skype tries the 64-bit libraries and complains, without looking any further.   This issue is easily solved this way.

1. I created a skype.conf file in the /etc/ld.so.conf.d directory.

# sudo vi /etc/ld.so.conf.d/skype.conf

2. I added the following line to this file

Installing Oracle Java JDK 7 in Ubuntu 

Installing Oracle Java JDK 7 in Ubuntu and updating all of the update-alternatives is a mystery to me.  I can easily download the Oracle Java Sun JDK and put it in the correct directory, but getting all of the links to put put in the correct location is a pain in the ass.

Thank god for the guys at WebUpd8 who maintain a Ubuntu repository for getting the latest version of Sun Java installed on my machine.  I personally don't like to install a bunch of PPA's into my system, so I just do a manual approach as described in the article here.
