I'm a first time Mac user.
Aside from checking out the installed applications on my Applications folder, are there other ways to find out what applications have been installed on my OS X Lion?
When I tried out the Terminal, and then assumed that the IRB (Interactive Ruby) or Ruby was installed, so I typed "irb" and it did work. It ran the Interactive Ruby and I was typing simple Ruby commands then!
I tried typing "python" too and the Python prompt then appeared. I typed some basic Python commands like "print 'hello world'" and it worked too!
I was thinking if there was a way to find out just like the Add/Remove Programs that I was used to when I was still using Windows XP/7 back then.
