It's discussed here [2] by it's primary developer. And here [3] is a good write-up about it. JMH is...

All the OSGi related contents we have seen so far during previous blog entries are related to backend systems.

Let's get productive What I want to share about goes beyond job description or industry. You may be a developer, a customer rep, a QA specialist, a manager, or CEO. You may be in software, or aerospace, or fashion, or farming. No...

A few months ago I pushed into the Liferay 's plugins repository the ability to write Scala code in the Liferay portlets but, to be honest, the support was quite poor since the Scala code was only allowed in portlets and you needed to create a new kind of portlet through the create.sh script located in the portlets folder. A couple of weeks ago I got a chance to resume the work on...

When is breaking something not a bad thing? When it's done with purpose. When the result is better than the original. So, if you know you have broken something, and that means it's broken for everyone, why stop with just the currently required change? Why not fix everything that was wrong in the first place? If an API was bad, and you had to make a small...
