If you're looking for a job in industry, my reply is to learn whatever is hot right now: C++, Java and C#--and probably Python, Ruby, PHP and Perl too. If, on the othe..

http://www.paulgraham.com/lispfaq1.html What is Lisp? Lisp is a family of programming languages descended from a language John McCarthy invented (or more accurately, discovered) in the late 1950s. The two main dialects now are Common Lisp and Scheme. We're working on a new dialect called Arc. How can I learn Lisp? The way to learn any language is to write programs in it. You have two main dialec..

http://www.paulgraham.com/icad.html May 2002 "We were after the C++ programmers. We managed to drag a lot of them about halfway to Lisp." - Guy Steele, co-author of the Java spec In the software business there is an ongoing struggle between the pointy-headed academics, and another equally formidable force, the pointy-haired bosses. Everyone knows who the pointy-haired boss is, right? I think mos..

http://jimbokun.github.com/programming%20languages/2012/09/23/small-and-fast/index.html My favorite article comparing programming languages is The speed, size and dependability of programming languages by Guillaume Marceau. Guillaume plots program size against execution time for programs written in various languages, implementing benchmarks from The Computer Language Benchmark Game. With the X a..
