I like to make web and mobile apps. I once wrote a post about the use of PHP frameworks that lots of people actually read.
I do front-end development using things like HTML5, jQuery, and responsive design.
For back-end development I like a bit of Python and Django, but I also use PHP if I really have to.
I also write mobile apps in HTML, but I'm getting there with writing native Android apps too.
Integrate and log all your exceptions with no effort.
