Charles, In 1990, I was working for a respectable engineering company that had computers doing drafting ( Intergraph ). They were powered by a mainframe, using a language by DEC.
I wanted to impress the IT guy, and was trying to learn as much about it as I could. Fortunately, this guy was pretty smart. He said "David, take my advice. The stuff we have here is crappy junk and will be obsolete, before you know it." I thought he just didn't have the patience to work with me. But I am glad I listened to him. Because, since leaving that company I have never seen such a system. Ever since then when some new computer thing came out, I was impressed, but not as excited. I feel like most of my computer knowledge is useless. Companies don't care what I used to know. They only care about what I can do with the software that they have on their computers. They all seem to want years of experience with AutoCAD 2008, when most companies are just now getting around to buying it. The dilema is you can't get the experience unless you have the job. David
