Tue, 13 October 2009 Chariot's Eric Snyder works in both Java, Spring-based applications as well as with dynamic platforms such as Ruby on Rails. He brought CouchDB to our attention earlier this year, and we thought we'd share some information about it with our listeners. Apache CouchDB is a RESTful web-centric document-based database system written in Erlang. It can be used either directly using RESTful mechanisms or via a wrapper API in a number of languages.

Fri, 14 August 2009 Rob Harrop is the lead engineer on SpringSource dm Server, and is a key contributor at SpringSource. He co-authored Pro Spring, a seminal work in helping developer understand how to best use the Spring Framework. In this podcast, I talk to Rob about OSGi and the Spring dm Server. We discuss the state of OSGi development, how it differs from traditional web-based Spring application development, and recent advancements in the technology. We also briefly discuss the recent merger announcement with VMWare corporation. Point of disclosure: Chariot Solutions is a SpringSource development and training partner. Show Notes: - The official OSGi R4 specification can be found here.
- Information about the SpringSource dm Server can be found on the SpringSource Team Blog, and on the official site.
- The RFC66 specification (standard OSGi web container) is not yet published, but Rob has a good post from May outlining how dm Server approaches implementing a draft version.
- Lots of information about Spring dm Server can be found on the developer forums.
Coming in October is the SpringOne 2GX conference, and in November we will offer a one-day seminar on Grails, Spring's agile Groovy-based web development platform, with Jeff Brown of SpringSource.

Tue, 11 August 2009 Our interview with Alex Miller focused on his work on Java Concurrency and also on Terracotta, the clustering technology which replicates graphs of Java objects between multiple Java virtual machines. Developers working in environments needing high concurrency should definitely review the most recent Java Concurrency API. Here are links to some of the topics we spoke about:
- Alex's DZone Core Java Concurrency Refcard is located here and is a good start for researching the Java 6 concurrency features. Of particular note is Table 1 on Page 1, which lists the key concepts that should be understood before delving into solving concurrency related problems.
- Discussion of various thread management mechanisms, which include Task Executors
- Discussion of Locks versus the traditional synchronized keywords, and ReadOnly and ReadWrite lock mechanisms
- Concurrent Maps, CopyOnWriteArraySet and CopyOnWriteArrayList (among others) provide map, list and set semantics, but are optimized for highly concurrent access in reading and manipulating these collections
- You can read Alex's blog postings on tech.puredanger.com
- The Lambda Lounge is located in St. Louis, and is located at www.lambdalounge.org.
- The Strange Loop Conference website is available at www.thestrangeloop.com.
Enjoy, and thanks, Alex! Ken Direct download: ChariotTechCast-08-10-2009-Alex-Miller.mp3 Category: podcasts -- posted at: 12:00 AM |

Fri, 17 July 2009 I had a great conversation with TechnicallyPhilly's Sean Blanda last week. We talked about how the Philly IT scene is still lively, and about how he and his two compadres Brian James Kirk and Christopher Wink gather and write up news on their lively and informative website. Technically Philly covered our Philadelphia Emerging Tech show in the spring ( article here). Some of our topics of conversation have related articles: - Someone who bikes a lot on the trails in Philly (we have a lot of good road biking trails here) wrote an app to track crime on the trail.
- Read their article about recycled machines ending up in Ghana
- Read up on the state funding issues for Ben Franklin Technology Partners, a capital group based in Philadelphia.
Enjoy the website. You can hit it from www.technicallyphilly.com or www.tphilly.com if you don't want to type so much, and it's iPhone friendly. Direct download: July14-TechCast-TechnicallyPhilly.mp3 Category: podcasts -- posted at: 12:00 AM |

Wed, 13 May 2009 JSR-299, the API formerly known as WebBeans, is a Java-based configuration and dependency injection system for the Java EE platform. In fact, the JSR has been renamed as such with the short name JCDI, and the original title 'webbeans' went to the reference implementation, which is being led by my guest, Pete Muir of Redhat/JBoss. Pete and I discuss the JSR, what features it brings to Java EE, where to find information about the specification, and the WebBeans reference implementation. Links to information related to the episode: - Pete blogs on the in.relation.to site: http://in.relation.to/Bloggers/Pete
- Pete's presentation on WebBeans and JSR-299
- Pete's Seam 3 Presentation
- Upcoming talk on JSR-299, hosted on Sun's "The Aquarium"
- Good reference book on WebBeans available from the Seam website (current link here)
- Official JSR-299 public draft #2 docs
- WebBeans user forum on the SeamFramework site
