I would invite anyone in an IT department buried in demand for mobile apps to first take a look at Google Enterprise, before trying to develop everything yourself. There are many mobile capabilities already available in the Google world which are free to individuals and available free...
The easiest way to make your code run faster is to do less. At some point, though, you don’t want to do less. Maybe you want to do more, without it being any slower. Maybe you want to make what you have fast, without cutting out any of the work. What then? In this enlightened age, the ...
I started in the web performance industry – well before Application Performance Management (APM) existed – during a time when external, single page measurement ruled the land. In an ecosystem where no other solutions existed, it was the top of the data chain to support the rapidly evol...

Agile is not easy and implementing Domain-Driven Design (DDD) is not easy. I think my favorite part of the book is that the author realizes that, and also has a realistic perspective on what it takes to successfully use agile processes and DDD. The book starts out with a really nice o...
The Java Virtual Machine specification limits the size of generated Java byte code for each method in a class to the maximum of 64K bytes. This limitation will cause the JVM throw java.lang.VerifyError at runtime when the method size exceeds this limit. This method size restriction o...
Social media applications like Facebook walls, Linked-in dashboards and Twitter tweet-boards have inadvertently opened up a new paradigm of pushing data/information to the users. Enterprise IT applications, on the contrary, expect users to navigate to the information using designated U...
The Open Group’s first conference in Australia will focus on enterprise transformation. Speakers and a variety of sessions will place the transformation in the context of such vertical industries as finance, defense, exploration, mining, and minerals. As a prelude to the event, Briefi...
Hibernate is an open source Java persistence framework project. Perform powerful object relational mapping and query databases using HQL and SQL. In general the widely used libraries are well designed and implemented, and it's very interesting to learn from them some coding best pra...
