AdA
Programming language, named after Ada Lovelace, the first programmer. Really only used anymore in US Department of Defense stuff. Oh yeah, and Ada95, the most popular Ada compiler actually translates your code to C, then compiles the C. I love that.
Ada95 is not a compiler, it is a version of Ada, the most recent version, I believe. I am also skeptical of the idea that Ada is "really only used anymore" in the US DOD.
