A word many won't have heard since they were in nursery school.
However, in backward parts of the UK, there was once an Escort Cosworth which was registered with a numberplate which ended in these three letters... therefore, completely rationally, the car which had this numberplate was referred to as YUM, by fully grown adults.
Awiiiite guvnor, apples n pears, turkish baaf... 'ow did YUM get on at Brunters?
Mate, can't adam'n'eve it, YUM never 'it 200mph today either boss... and when me old chinaparked up... we saw a small elderly gent chuckle before he was driven away in his big boostin white Saph Cossie? Ye get me?
Yum is a great CLI application, with GUI front ends, similar to Apt for RPMs that makes updating, getting information about, installing and removing RPMs easy. It's used by Yellow Dog, Fedora Core, and RHEL (and possibly more distros I do not know about). When you install something via Yum, Yum automatically downloads and installs all dependencies of the package you want if you don't have the dependencies, putting an end to dependency hell if the package you want is in your Yum repositories.
A great Yum configuration file for the most recent stable Fedora Core that adds great repositories can be found at http://www.fedorafaq.org/samples/yum.conf
A random word that shows indifference. (In other words, you tell me about your day, I don't care but I have to say SOMETHING.. That's where yum comes in!)
Justin: I talked to Ashley today.. We got in a fight and she told me that I was worthless and a bad boyfriend and my hair is ugly and etc. etc.
Me: Yum!
