Bootstrapping Chef on Ubuntu 12 with Opscode Knife
Thursday, May 10, 2012
I enjoy using Opscode Chef since bringing up an automatically configured instance is fast and easy on any of our cloud providers. Ubuntu 12 having just been released, I took the opportunity to perform QA testing on it as well as verify that our cookbooks would work as expected. Using an Amazon EC2 published Ubuntu 12 AMI, I ran the "knife ec2 server create" command to create the instance and install our software.
Complex validation of CQ5 dialog fields using a custom Sling servlet
Monday, April 16, 2012
Dialog fields in CQ5 occasionally require validation that cannot be handled with static constraints or regular expressions. However, this type of validation can be easily accomplished by delegating the validation function to a custom servlet. The implementation details and code samples below describe a viable solution for most validation scenarios.
Maintaining Visibility of CQ Editables
Tuesday, April 10, 2012
Content elements such as multi-tab content controls and collapsible content sections are prevalent on modern websites. In an Adobe CQ5 authoring environment, a common business requirement is to allow the authoring of such elements in place. Such requirements necessitate the elements of the CQ authoring environment (edit bars, drop areas for paragraph systems, etc) to be hidden and shown as the content which they represent is hidden and shown.
Thoughts Concerning Serving Linked Data from Apache Sling
Monday, April 2, 2012
Reviewing the JCR specification as well as some of the Apache Sling documentation, I caught a wiff of congruity between the functionality they exposed and the tenets of Linked Data as they are popularly defined in relation to the Semantic Web (listing 1). What struck me about this was that the congruity seemed inherent to JCR and Sling and was, from what I can tell, unintentional. Realization of this happy accident gave rise to the question of the ease with which Linked Data can be housed and served using Sling and JCR and the faculties built into each.

Adobe CQ 5.5 & JMX
Friday, March 16, 2012
Starting with CQ5.5, Adobe (Day) integrated one sorely missed functionality to the product, JMX. As with any J2EE server, JMX makes it easy to manage and monitor an application and services in real time. JMX allows for central management of managed beans or MBeans which act as wrapper for applications, components and resources. A standard MBean exposes attributes, properties and operations, which can be accessed for monitoring and invoked for certain conditions depending on underlying logic. It also helps when you don't need to restart the server to make a quick and essential change. With CQ taking prominence in today's digital media centric world, custom components are being built at a rapid pace to support and integrate several software products. Managing these custom components will become easy with JMX framework.
