Learning AngularJS. Brushing up on HTML5 and CSS3. For me the greatest thing about angular is not its clean separation of concerns or its declarative natural, it's that it recognises that coding is only part of the solution; testing, maintenance, and debugging are just as important if not more important than the code itself.
Also, why is it that most organisations using PHP/ web applications think that monitoring is about whether the site is up? It is so depressing that these organisations do not understand or appreciate that it is the platform that is important right from the developers machine, the support desk, the production servers, the infrastructure, all the way through to the end users device; cutting code is not what contemporary software/ application development is all about.
