Ben Alex carved out some time to talk to me about the SpringSource Roo project, a very interesting and different take on Convention over Configuration Frameworks.

All of the major prior frameworks seem to use dynamic and meta-programming tricks to get work done.  Ben's team focused on taking advantage of the Java platform, and hence Roo is a fast, java-and-AOP solution for getting things done using existing APIs like JPA and Spring's APIs.  Applications are built using a command-line shell (even with code completion, just hit tab!) but in the end, they are just maven-based Spring projects.

You can find out more about Roo itself by visiting
www.springsource.org/roo

Mentioned in the podcast is the book "The Humane Interface" by Jeff Raskin.  Ben says that reading that book helped him form the basis for his ideas about Roo.

Ben Alex can be reached via twitter as @benalexau, and the #roo hashtag gets quite a workout.  We also suggest visiting the forums, as JIRA issues posted there are generally answered promptly.

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:
  1. The official OSGi R4 specification can be found here.
  2. Information about the SpringSource dm Server can be found on the SpringSource Team Blog, and on the official site.
  3. 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.
  4. 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.

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:
  1. 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.
  2. Discussion of various thread management mechanisms, which include Task Executors
  3. Discussion of Locks versus the traditional synchronized keywords, and ReadOnly and ReadWrite lock mechanisms
  4. 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
  5. You can read Alex's blog postings on tech.puredanger.com
  6. The Lambda Lounge is located in St. Louis, and is located at www.lambdalounge.org.
  7. The Strange Loop Conference website is available at www.thestrangeloop.com.
Enjoy, and thanks, Alex!

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.

This podcast episode is a recording of Michael Tiemann's keynote presentation from the 2009 Emerging Technologies for the Enterprise Conference.  Michael is RedHat’s VP of Open Source Affairs, and has a  long history in working on open source projects.  He is the president of the “Open Source Initiative,” and has served as the CTO of RedHat, and founded the first open source software company, Cygnus.

Michael’s talk focuses on "Exonovation", or innovation from an open community, and how it can make a product even better than a closed, controlled, proprietary effort.  It is a very interesting talk, and for those who want to follow along with the slides, you can go to http://www.chariotsolutions.com/slides/pdfs/ete2009-ExonovationTieman.pdf

Books discussed during the talk:
  1. The Only Sustainable Edge: Why Business Strategy Depends on Productive Friction and Dynamic Specialization:  John Hagel III, John Seely Brown - This book questions the zero sum gain theory espoused by Harvard Business School.
  2. Democracy in America: Alexis de Tocqueville (the link is a free transcript download) 
  3. Unlocking the Sky: Glenn Hammond Curtiss and the Race to Invent the Airplane by Seth Shulman.  Referred to when discussing the Wright Brothers' assumption that instability was a key feature of flight.
  4. As We May Think : Vannevar Bush, the Atlantic Monthly, 1945 - Vannevar imagined the Internet (or something eerily like it) in this paper.
  5. Outliers: The Story of Success - Malcolm Gladwell

I had been listening to Leo Laporte's tremendous This Week in Tech (or MacBreak Weekly) podcast, and found out about SquareSpace.com from the show. The crew was raving about how easy it was to use to publish web content, and how it blew away Wordpress in terms of productivity. So I set up a free trial for my personal account and was also suitably impressed. In doing research I found that SquareSpace is a Java-based platform, so, since the Chariot TechCast focuses on successful Java platforms, it made for a great fit. I did an interview a few weeks ago with the creator and co-founder,
Anthony Casalena, who is responsible for the technology backing the site.

You'll hear how Anthony created the site primarily to solve his own frustration with using blogging tools, and how the technologies are applied to serve a large number of customers on a handful of actual servers. During the lineup of the interview, SquareSpace offered us a sponsorship, and we accepted. If you use the keyword 'TECHCAST' during your free trial to register for a plan, you'll get 10% off the cost of any of their plans.

Technologies mentioned in the podcast:
  1. Apache OJB - Object Relational Mapping API for Java
  2. Apache Tomcat - web application server
  3. SQL Server - relational databases

On today's show, we feature the Manning author's Q&A  forum.  Marjan Bace is the co-founder of Manning Publications, which publishes books on a wide variety of technical topics. 

Last year at ETE, Marjan assembled the web framework shootout (if interested...  part 1, part 2).  This year Chariot asked him to assemble an author’s forum, where he takes questions from the audience on writing books for publication.

The panelists are Dan Allen, author of Seam in Action, David Black, author of Ruby for Rails and the upcoming title, The Well-Grounded Rubyist, and John Resig, author of the upcoming Secrets of the Javascript Ninja.

This is a very interesting look at what it takes to write a book, what it demands of you, and what you end up learning in return.  Marjan, Dan, David and John did a great job.

One of the highlights of the 2009 Philadelphia Emerging Technologies for the Enterprise Conference was our afternoon keynote from Jascha Franklin Hodge, from Blue State Digital. 

Mr. Franklin Hodge cut his social media teeth working on the Howard Dean campaign.  Blue State Digital built and managed the Barack Obama campaign website, which provided news, email correspondence, coordination with official and unofficial leaders on events, YouTube and video/audio media, and more.

This keynote highlights the successes of properly using the internet and social media to run a successful campaign including contrasts with the McCain effort as well as discussion of lessons learned.

A copy of the presentation slides is being processed, and will be made available soon.  For now, you can view the slides from an earlier presentation at MIXX Canada, on Slideshare

Andy Hunt is co-founder (along with Dave Thomas) of the Pragmatic Programmers.  Their seminal book, The Pragmatic Programmer, gave every developer a nudge, and started their publishing company, The Pragmatic Bookshelf.

Andy's latest book (his seventh) is Pragmatic Thinking and Learning, Refactoring your Wetware.  His keynote at 2009 Philly Emerging Tech covered topics from the book, and was a fantastic walk down memory lane (sorry, couldn't resist).  Seriously, folks, his talk was all about maximizing your ability to learn and retain knowledge.  Here are some great books he mentioned:
  1. Andy Hunt:  Pragmatic Thinking and Learning
  2. Mihaly Csikszent: Flow: The Psychology of Optimal Experience (P.S.) 
  3. Dan Pink: Whole New Mind
  4. Betty Edwards: Drawing on the Right Side of the Brain
You can find Andy's writing on the Pragmatic Bookshelf or on his blog, toolshed.com. For a mind map of his key topics, click here.

The second part of the podcast includes audio from the Destruction Zone.  Pictures were posted at our ETE Flickr Group.  The company, Wondergy, allowed us to tear apart old fax machines, printers, computers and cell phones, and worked with Chariot to line up green recyclers to haul it all away.  You'll hear a little audio, although distorted, of the bashing of a copier, as well as an interview with Wondergy's Ken Fink, on how the project came together.

In this podcast, we speak to JBoss's Emmanuel Bernard on the future of validation using JSR-303, the Bean Validation framework. JSR-303 aims to provide an annotation-driven mechanism to mark plain old java beans with annotations, such as @NotNull, @Min, @Max, and can support custom validation annotations as well.

JSR-303 is part of the Java EE 6 suite of JSRs and will be used automatically out of the box by frameworks such as JSF 2.0. Emmanuel also goes into some detail about the current state of Hibernate Search. Useful links:

  1. Hibernate Validator (4.0.0, which is currently in alpha 3, is the reference implementation of JSR-303).
  2. The Bean Validation RI RoadMap, which contains a link to useful resources such as the updated JSR (more up-to-date here than on the JSR page itself).
  3. Emmanuel's Hibernate Search in Action, published by Manning, and co-authored with John Griffin.
  4. Hibernate Search Project Homepage
  5. JSF 2.0 and JPA 2.0 project homepages
  6. Emmanuel Bernard's blog, No Relation To.

Last Thursday I had an opportunity to sit down with Dan Allen and talk about the Seam Framework.  Dan was a great resource for learning about Seam.  This is the second of a two-part interview, where we focus on the future of Java EE 6, including JSR-299, formerly known as WebBeans, and how Seam will change as the Java EE specification evolves.  We also discuss varying front-end technologies such as Flex and AJAX, and a bit about workflow. 

Resources we mentioned in the talk include:

  1. Granite DS  - graniteds.org - A Flex remoting framework that includes support for Seam as well as other platforms such as Guice, Spring and POJOs
  2. Flamingo - Another Flex (and JavaFX) remoting framework that exposes Seam and Spring services using a variety of protocols including AMF and Hessian.
  3. The JSR-299 Specification.  Dan claims it is a decent read and it seems to be  something every Java EE developer needs to be aware of at some point in the near future.
Show notes are available at techcast.chariotsolutions.com.

Last Thursday I had an opportunity to sit down with Dan Allen and talk about the Seam Framework.  Dan was a great resource for learning about Seam.  This is the first of a two-part interview, where we focus on the Seam framework itself, how it differs from Spring and other frameworks, and how it marries JSF and POJO as well as EJB components, providing a stateful view of the world and making programming easier for APIs such as Java Persistence.

If anyone has been listening since our very first Podcast, we covered flex way back in February with our own Peter Paugh.  But when we had an opportunity to talk to James Ward of Adobe, a Flex evangelist and someone passionate about Flex as well as Java development, we jumped at the chance.

James was a great interview, a fantastic source of information, and will be a good listen.  We talk about Flex, Flex Builder, the open sourcing of various technologies, the Open Screen project, why Java developers should care, and many more topics.

Helpful links and resources:
  1. The Census Benchmark App - James has been working on this for a while.  It is a benchmarking application comparing various RIA / AJAX technologies and speed of operations like sorting, table management, etc...  An interesting way to see relative performance metrics.
  2. Flex Home - the main Flex developer site.
  3. Adobe Open Source - James mentioned this site a lot.  This is where Adobe places all of its' open-sourced technologies.
  4. The Flex SDK Download Page - The open source, freely available SDK
  5. The Shockwave File Format - Adobe has fully documented the SWF file format.
  6. The Open Screen Project - a consortium including Adobe that wants to push Flash onto mobile devices by opening up the standards and exposing the flash player.  More info at the FAQ
  7. Gnash - an open-source flash movie player mentioned in the show
  8. AMF - (pdf download) the ActionScript Message Format - Read up on this, as Flex supports AMF for fast transfer of data between client and server.
  9. BlazeDS - A server-side Java remoting technology using AMF.
  10. LiveCycle ES - A commercial, J2EE-based server platform for Flex development from Adobe.
  11. FXStruts - the FXStruts Library allows Struts developers to expose java objects within a Struts application using AMF
James Ward's blog and useful information is located at www.jamesward.com.   The Flex Show episode 50 is also a good listen...

In this third interview about startups and technology, Ken interviews two of the founders of TapInko, a marketplace for buying and selling ads.  Ken spoke to Nicolas Warren and John Newell, who architected their application in Microsoft .NET. 

What we find interesting about these three ventures is the differences in approach.  One team focused on getting ideas out quickly, another focused on application development using a combination of PHP and Python, and this team focused on .NET and building out an application framework first.  Listen to this team's approach, as we start in the middle of a conversation about building software out of nothing.  (I need to credit that quote to Dave Thomas of the Pragmatic Programmer...)

Correction: I had originally mentioned that John Valentine was an interviewee, but it was, in fact, John Newell. My apologies.

This is the second in a three part series on technologies and startup companies.  Ken sat down with the founders of PhrazIt, a social web site focused on short reviews of 30 characters or less.  The team originally started, and will continue, a concept called Study Buddy, which would allow college students to find like-minded study mates.

The three founders, David Kosslyn, Ryan Schoen and Shankar Ramaswamy, are college sophomores at MIT and Harvard.

This is the first in a three-part series of interviews we did at DreamIt, a startup incubator located at Drexel University's science center.  DreamIt sponsors 11 different startups, houses them in the incubator, and gives them some nominal funding and education on the startup process.

Snack Feed uses the social web to share videos between users.  The team members built a FireFox plugin that you can use to publish content to four major vendors at the same time, and also uses PHP and is beginning to work with Google App Engine for some of its' technology.

Ken spoke to Founders Jason Cyril Laan, Christopher (CC) Laan, and Mika Ohiorhenuan.

This week we feature an interview with Toby DiPasquale of Invite Media.  Toby and I discuss the Map-Reduce algorithm, which is the engine that powers Google's indexing and data processing systems.  We start off by discussing how Google started indexing pages, using traditional methods such as C/C++ routines.  Quickly this became unmanageable, as the amount of data to index outstripped the processing power and traditional data transformation paradigms.

Toby and I then go into discussing Map Reduce, which was originally posited as a thesis and then published as a seminal paper in the community.  Map Reduce has been implemented by Google, and as we'll see in the podcast, others followed suit and created the Hadoop engine, a Java-based Map Reduce solution. 

We talk about Hadoop and it's various subprojects, and then get into a discussion on Amazon EC2 and the Cloud Computing movement, including why it is valuable to organizations who want to scale from one to potentially dozens of CPUs.

I'll post the show notes early next week at http://www.chariotsolutions.com/podcasts/techcast/shownotes.  Until then, enjoy the show and comments are always welcome.

Note:  the podcast audio got a bit distorted on Toby's side, but I don't think it distracts too much.  Rather than re-record the interview I'm presenting it as-is.

This week I'm starting an occasional series of interviews on non-Java or non-traditional platform development.  I am looking for reasons that people choose Ruby on Rails, Python, and other languages in lieu of Java EE or .NET, especially in startup organizations.

 This interview features Chris Cera, the CTO of Vuzit (http://www.vuzit.com), which is a document web services startup funded by DreamIt Ventures (http://www.dreamitventures.com), a Philadelphia-area seed funding program. We talk about his experiences with various dynamic languages, including Perl and Ruby, and why he feels Rails is a great development platform for his company.

At the end of the interview Chris and I get into a discussion about what makes a good programmer / developer.  I'll have information on the shownotes page next week, at http://www.chariotsolutions.com/podcasts/techcast/shownotes.

Thanks for listening.  Feedback can be directed to me at krimple@chariotsolutions.com.

Today we feature the second of a two part session from the 2008 Emerging Technologies for the Enterprise Conference.  The session, entitled "Web Framework Shootout," was assembled and moderated by by Manning co-founder Marjan Bace and was one of the highlights of the conference.  Speakers included Yehuda Katz,  Chad Davis, Max Carlson, Robert Hansen, Bear Bibeault, Chris Richardson, Dan Allen, Emanuel Bernard, Peter Armstrong and Obie Fernandez.  Quite a group!  

I have lightly edited the quiet patches, and edited out one or two questions where people were speaking off mic and nobody responded.  If you hear dropouts, it's because of those reasons, no major content was left out.

This half does contain a few curse words and some heated debates.  There is a very interesting exchange between the Java and Ruby camps.

The show was broken into two parts due to the fact that it ran rather long (over an hour).  I have lightly edited the quiet patches, and edited out one or two questions where people were speaking off mic and nobody responded.  If you hear dropouts, it's because of those reasons, no major content was left out.

The second half promises to be even more entertaining than the first.  I'll publish that segment next week, as we need to beep out a few choice words as the conversation got quite heated.  Enjoy the podcast!

If you're at all adventurous, you've probably loaded Linux on a PC sometime in your life.  Some of us avoid that pain by running (screaming) to Mac OS X, where we have a nice, pretty view of the world behind shiny and metallic, stylin' boxes.

Not Andy Oswald.  He's a tried-and-true Linux OS guy (Ubuntu, actually).  When given a Mac Mini to play with, he really enjoyed kicking the tires, playing with those fun apps, but when it got down to brass tacks, he felt more at home on Linux.

Once Andy got his MacBook Pro, he dug around and found a small community of users running Ubuntu on the Mac.  And he's now one of them.  Learn how he fared by listening in.  If you do this yourself, we highly recommend thinking twice, backing up, and using the right machine for the job (NOT YOUR WORK ONE!)
