Never really thought about it but now that I write them all out, it looks absolutely terrible.

• Perl
• SPL
• Prism
• bash
• SQL
• VBS
• HTML
• CSS
• Javascript
• C#

The C# work was contracted out (and I do regret allowing it in) but the rest is used by me -- no one else to blame. SPL (sybyl programming language) and Prism (GraphPad macro language) are a bit odd but important in my field. I've just started adding CSS and Javascript but that's just out of laziness. Time permitting, I'll replace the VBS with a par executable.

Luckily, I rarely have to work with C or Fortran anymore but I occasionally get wrapped up in small, specialized "languages" like SLN (sybyl line notation).
