I started out with Perl and I still occasionally use it today. There's nothing I especially like about Perl that other languages cannot do just as well, or even better, but at the time I started using it, it seemed pretty powerful. It's still a formidable language and a viable means to build a solution for some problems—provided you don't have to collaborate with anyone. It's hard to find people willing to work with Perl these days, at least where I'm based.

I also help maintain some web applications built with VB.NET interfacing with IBM AS-400 and iSeries midrange servers. Which means some RPG coding as well. Can't say I enjoy that too much, pretty dull, but RPG is straightforward enough.

Basically, I work with VB.NET because it's not my code and there would be little advantage to converting it to be in C#. Very much a "if it ain't broke, don't fix it" situation since the clients depend on uninterrupted service.

I mostly work with—and prefer to use—C# and JavaScript these days.
