For the I.T. geeks of Warpath: Which programming languages are dead?

[skinsguy]

So about ten years ago, I decided to go back to school and get my degree in Information Technology/programming. During my years at college, I was exposed to several programming languages: HTML (which I had learned on my own,) JavaScript, C#, and Java (which I had a hard time with.)

My present I.T. position is with a non-profit agency (so pay is low) and I haven't had to do any programming in awhile. When I had first gotten hired, my boss wanted me to learn this old, antiquated database programming language called "Clipper". It was the hardest thing for me to learn, because the code seemed like "spaghetti code" (programmers will know what I mean by that.) After a few years, we decided to go with an outside vendor for our software, so my I.T. duties relegated back to supporting the vendor software and other miscellaneous computer stuff.

So now, my girlfriend and I are talking marriage and I will probably move to where she lives, which has more job opportunities than where I am currently living. I would like to get back into programming, but I'm not sure which programming languages are being used the most. I am more willing to go back and refresh my memory with languages that I already sort of know, rather than to have to learn a brand new programming language. I enjoy more web-based programming than anything else, which means I'd probably at least need to learn ASP or AJAX if I were to land a job with that.

But, for any of you guys who might be in the know, which programming languages are hot right now? Which ones are pretty much useless nowadays?
