This post is for programming language fans.
FORTH is a pretty interesting language. It's one of the oldest programming languages.
It was originally invented by Charles Moore to control telescopes in the early days of computing:
(Also make sure to google for FORTH and check the Wikipedia entry, etc.)
The classic FORTH language tutorial, the book "Starting FORTH", is now available online.
Check it out here:
The book's author was Leo Brodie:
(Again, google for him.)
I was lucky enough to find a copy of the original book (in hard-cover!) many years ago, when I was fairly new to programming, and bought it on the spot :), even though it was a bit expensive for me back then.
I enjoyed reading it, and playing around with the language using a FORTH interpreter.
Now you can read the entire book online at the above URL if you're interested in going FORTH :)
Here is the introduction page, which is quite interesting too, and may spark your interest in FORTH:
Some people say that is more efficient than assembly language for certain types of programs.
Whether or not that is the case, I certainly found it a fun and unique language to program in.
YMMV, of course. Only one way to find out ... (TM). 
UPDATE: I checked out a FORTH implementation, GForth (that's GNU FORTH) v0.5.0 for DOS. Tried the Windows version first but the EXE gave some error, and I didn't want to bother right then with building it from the Windows source. There is also a Linux version which you can try out; you may have to build it from source using the usual configure / make / make install method (plus maybe some tweaks). You can find the GNU FORTH site via Google: http://google.com/search?q=GNU+FORTH
Anyway, the DOS version of GForth worked okay. I could enter a few FORTH expressions and they ran right.
Also defined and ran a FORTH word or two to check a bit more. That worked too. Looking forward to doing some FORTH programming in my spare time ...
