ZK Developer's Guide: Developing responsive user interfaces for web applications using Ajax, XUL, and the open source ZK rich web client development framework
“ This being human is a guest house. Every morning is a new arrival. A joy, a depression, a meanness, some momentary awareness comes as an unexpected visitor...Welcome and entertain them all. Treat each guest honorably. The dark thought, the shame, the malice, meet them at the door laughing, and invite them in. Be grateful for whoever comes, because each has been sent as a guide from beyond. ” ― Rumi
