This content is moving... The new home of our emerging technology podcasts and screencasts is Chariot Emerging Tech. The current feed will be retired soon.

Rod Johnson is well known for his work creating and leading SpringSource, and the Spring Framework. But did you know he recently started working with TypeSafe organization? He's advising them on their board of directors, and he's working on his own Scala hobby application. He has some views about the language, how to start using it, complexity vs readability, the "No Frameworks" movement, and more. 

If you want to listen to Rod's history working on Spring, have a listen to episode 74.

This interview is a walk through the lead up to and the creation of the Spring Framework with no founder Rod Johnson. Recently, Rod left the company sponsoring Spring, VMware Corporation, and joined up as a board member of TypeSafe to advise them on the future of Scala and other projects.

The podcast, then, is broken into two parts - the first part focuses on Rod's history in creating Spring, what makes it compelling, and how it has developed over the years.

The next part, which will appear on TechCast #75, will focus on Scala, a language that has become more popular of late. Rod is currently advising TypeSafe, the sponsors and creators of Scala, and he has been working on a project for several months totally written in the Scala language. 

Disclosure Note - Chariot Solutions is a VMware consulting and value-added training center partner. 

Enjoy this two-part interview.

This techcast episode features the open source PDF API developer Bruno Lowagie. His iText library has been used by many Java developers. One of the earier open-source Java APIs, iText was originally written to provide PDF version 1.3-compliant output. This was not the first API that Bruno created to handle PDF, as we'll hear in the interview, and also not the first to be open-sourced.

We'll hear how Bruno has participated in the PDF specification, has worked with various document management concerns including encryption, forms processing, and long-term archiving of PDF document formats. One very interesting section concerns how he approached licensing, and some of the challenges faced by developers when they are looking at dealing with open-source users versus paying clients, and how that informs the decisions of his company has he moves the library forward.

For information about the iText library, in both the commercial and open-source licensed versions, you can visit

Rebooting this podcast starting THIS WEEK!  I hope to have one developer news every other week, starting today.

This summer has been anything but a vacation, with our training exploding and me spending lots of time in the classroom. I've also penned two updates to Spring Roo in Action, so I've been pretty busy. But I realized we haven't been updating the DevNews, so let's get back to it, shall we?

Kohsuke Kawaguchi (@kohsukekawa) is the creator of Jenkins, a continuous integration tool he wrote a number of years ago as a way to verify that he checked in his files and didn't affect his multi-developer build. It is safe to say that Kohsuke wasn't the only one with that problem. A huge hit, the Jenkins CI server, which at the time was known as Hudson, reached a wide adoption level, with people installing it officially and even under their desktops in many IT development shops. 

Kohsuke discusses the challenges in developing a tool like Jenkins, which changed names after the new owner of Sun, Oracle, decided that it owned the trademark to the Hudson product name. Oracle has contributed Hudson to the Eclipse foundation, and Kohsuke has continued developing Jenkins, sticking to a build per week strategy, conducting all team meetings in an open IRC forum, as well as documenting project status on their website,

We talk about current efforts, including supporting the plug-in developer community, writing plugins in Ruby, the CloudBees projects he's working on, and more. Thanks again to Kohsuke and Lisa Wells, who lined up the interview.
