LISP

since 1958 (earliest usage recorded on this site was 1970)

Lisp (or LISP) is a family of computer programming languages with a long history and a distinctive, fully parenthesized syntax. Originally specified in 1958, Lisp is the second-oldest high-level programming language in widespread use today; only Fortran is older. Like Fortran, Lisp has changed a great deal since its early days, and a number of dialects have existed over its history. Today, the most widely known general-purpose Lisp dialects are Common Lisp and Scheme.

Lisp was originally created as a practical mathematical notation for computer programs, influenced by the notation of Alonzo Church's lambda calculus. It quickly became the favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, and the self-hosting compiler.

Only in one class. CDC6400 LISP, which differed from "normal" LISP 1.5 by having CSR in addition to CAR and CDR. And in other "delightful" ways.

1983 Franz Lisp on a VAX. Emacs Lisp since 1997. Scheme from time to time.

Learned it while in high school on the BBC micro

Lots of Insane Stupid Parentheses indeed. I've made a few attempts at learning Lisp and its co-demon Prolog, but my mind just doesn't work that way.

Started in uni, continued as emacs scripting. Don't use it much.

Does Emacs lisp count? That's what I've used more than anything else.

Uche

1992–1995

jancona

1993

Used it to do natural language processing for my grad school AI course. I liked it, but never got to use it again. I need to try Clojure one of these days.

jtauber

1994

I initially had to learn this for a computational linguistics class. Never used it outside of that although have a new found appreciation for it now.

zellyn

1995–

Learned it in my first Summer session in college. Loved it ever since.

Had to learn it for an exam at University (along with PROLOG and Ada). I failed the exam. The year after it was replaced by Python. I passed the exam. Good for configuring yer emacs, though.

duke_sam

2002–2003

Used for AI projects in college, loved it's elegance.

Ancient and crufty, full of antiquated names for things, and flippin' awesome. I came to Clojure via Lisp and then back to Lisp via Clojure. Feels appropriate somehow. I've also written a small Lisp interpreter which I believe is a rite of passage for any Lisper.

Started out with Scheme in college, continuing through the present with mostly Elisp.

2005

Read and typed just to become familiar, but I appreciate the 21st century, thanks.

Played around with for fun but never created a real project with it.

The closest I've come to learning LISP is when I was inspired to read ANSI Common LISP (http://bit.ly/apzLR4) by Paul Graham (I think in 2006) after reading his essays.

The most amazing language ever.

Started to read lots of LISP and I'm in the process of learning all about it (and Clojure)

Still learning it. I find LISP fascinating, it teaches me to think better.

First was learning it in high school on my own by books. Then was learning it in college for an AI class, again from books and manuals. Now studying Clojure.
