Random attendees at Devoxx were asked, on the final day, to talk briefly about one new thing they'd learned at Devoxx, one interesting new project they'd heard about for the first time, or one technique they'd like to try out as a result of something they'd heard at Devoxx.

Do Your Iterators Always Fail-Fast?

Bharath Ganesh — Sat, 21 Nov 2009 13:39:03 +0000

The iterators of the Collection implementations of the Java runtime throw a ConcurrentModificationException[1] when they detect that another thread has modified the Collection while a thread is iterating over it. Such iterators are generally called fail-fast iterators. Article Type: Opinion/Editorial

Logging on a Per-Thread Basis

fabriziogiudici — Sat, 21 Nov 2009 12:58:00 +0000

As far as I know, most of the logging facility configurations enable you to specify the maximum size of a log file, how many will roll, where data is fed to and eventually dispatching multiple destinations in function of the log level. I've found nothing (apart from a couple of discussions on java.net forums) about splitting logs in function of the thread - that is, all the logging from a thread...

An Introduction to Feature-Driven Development

stephenrpalmer — Fri, 20 Nov 2009 15:58:19 +0000

Feature-Driven Development (FDD) is one of the agile processes not talked or written about very much. Often mentioned in passing in agile software development books and forums, few actually know much about it. However, if you need to apply agile to larger projects and teams, it is worthwhile taking the time to understand FDD a little more

Testing PDF files with Canoo Webtest and Maven2

fgaucho — Fri, 20 Nov 2009 15:49:12 +0000

This week I received one of that lovely and tricky tasks: to learn Canoo webtest, test it and prove its usefulness to the project in three days - convincing the managers that it should be part of the project. The goal of the project is to produce a finance report with ~200 pages and that report should be validated through a zero-errors acceptance tests. Several tools were considered, including...

The Abuse of Utility Creational Methods

egolan — Fri, 20 Nov 2009 15:25:42 +0000

Sometimes I encounter code, which obviously the writer had good intentions in making the development easier and faster. However, in my opinion, it is not. It’s a kind of code that magically creates new instances and attaches one to another.

It was announced yesterday that closures would be added to JDK 7. Mark Reinhold made the announcement at the Devoxx conference. Before today, Sun could not reach a consensus on the inclusion of closures in JDK 7. Three proposals for closures were submitted to Sun over the last few years. With the JDK 7 schedule extended to September 2010, Reinhold seems to think that now is the time to...

Devoxx Day 3: Conference Day 2

geertjan — Thu, 19 Nov 2009 22:20:44 +0000

Tried to attend a few sessions today, at Devoxx 2009 in Antwerp, Belgium, that I wouldn't normally have done, i.e., sessions that didn't necessarily grab my initial interest. If you only attend sessions that appeal to you, you're potentially missing out on discovering completely new tools or techniques. So, some of those are included in the list below.

Terracotta is having a defining year in 2009. Their Hibernate and EHcache products provide innovative methods for object-relational mapping and distributed caching. The Terracotta 3.1.1 server is already extremely fast, but Terracotta is trying to make it even faster.
