Alternative syntax to GET in url
I've inherited terrible code in the past, but one idea in there struck me as a logical step. It's to use non-standard get queries for links inside the application. So instead of /search?category=23&city=Venice when applicable, use /search/category-23;city-Venice These kind of uris get parsed for comfortable use by the system and ...

Dynamically printing javascript
I recently ran into a situation where it made sense (at first at least) to have my server-side code not only "print" html, but also some of the javascript on the page (basically making the dynamic browser code dynamic itself).

Why is Jboss "better" than Tomcat?
Hi all. I'm currently starting a new app development. The app architect insists we use JBoss5 because its "better". Do anyone has a wider definition of "better" (if its the case)?
