The last script I will share with you for now is one that I call on screen helper. This is also a simple script, but very useful when it comes to animations, transitions, and effects. Essentially all it is doing is adding classes when a given element enters the screen and removes them when it leaves. Combine this with some css3 and you have an endless amount of cool things you can do...

Here is another script that we developed for the redesign of Liferay.com.

Thanks to Jolokia we have a lightweight layer on top of the MBean Server infrastructure which allows to query our JMX data over the http protocol. The architecture is very simple: I have...

This is an adaptation of a blog I wrote for Wolters Kluwer March 2011. Everyone knows that data and information are subtly different things. Data is worthless unless it can be turned into information. General consensus says that data turns into information when it is analyzed, interpreted, enriched, redacted, linked etc. The moment data is touched by one of these processes,...

  Twenty years ago, June 1993, Adobe introduced its Acrobat software for creating and viewing electronic documents.

As you probably know in version 6.1 Liferay introduced the mobile device rules feature. However if you haven't followed the discussions and presentations about it, you may be under the wrong impression that is't very limited. Some people even claim it doesn't work. Judging by the number and type of questions I still get asked now days, I think I know where most of the confusion comes...
