A common question I get during Tapestry training sessions is: Why can't Tapestry reload my services as well as my pages and components?. It does seem odd that I talk about how agile Tapestry is, with the live class reloading, and how nicely OO it is, what with services ... but when you move common logic to a service, you lose the agility because services do not live reload.
This came up yet again, during my latest training session, in London.
I've considered this before, and I've... more »

Well, that's what I get for waiting until the last day ... by the time I had a chance to put together a submission or two for JavaOne 2010, the site was down (from about 10pm on). Kind of frustrating, I was looking forward to talking about Tapestry and Clojure (my main speaking staples) in front of another big crowd.

I’ve done a fair bit of fairly small open source updates recently.
jQuery PeriodicalUpdater: The main function now returns a handle that can be used to call stop(), thereby ignoring any updates that may come back and preventing future updates from being sent.
TestingLabs: I released TestingLabs 0.4 to work with Grails 1.2.0. Had a bug with versioning under Grails: More info on JIRA.
Presentations: I’m now storing the slides for my presentations on GitHub. They’re... more »

I think I've come to understand why Eclipse leaves me always feeling a bit frustrated. Yes, it is more stable than IDEA, uses less memory, has some documentation, and a lot of acceptance ... but even so, it just leaves me cold (and I was an early adopter, signed up for the beta way back in 2000!).
Keystrokes are not modal
The fact that I can type a common keystroke into an Eclipse window and not know what it will do is painful. How a keystroke is interpreted depends on what... more »

As I previously mentioned in “Free lunches, mousetraps and the Actor model“, Edward A. Lee wrote an interesting article entitled “The Problem with Threads” in which he advocates leveraging the actor model in popular languages (such as in Java) as opposed to adopting an entire new paradigm (like Erlang). He states:
We should not replace established languages. We should instead build on them.
It appears that more than a few hip people agree with his line of... more »

I’m currently in chapter 12 of Growing Object Oriented Software Guided By Tests and thought I’d share another good tidbit from one of the asides:
Put Tests in a Different Package
We’ve adopted a habit of putting tests in a different package from the code they’re exercising. We want to make sure we’re driving the code through its public interfaces, like any other client, rather than opening up a package-scoped back door for testing.
Good point!... more »

You might call it petty, you might call it vain, but I've aspired to be recognized as a Java Champion for the last couple of years. The process by which you are selected for this is a bit secretive, but I've finally gotten the nod and joined the roster.
My larger goal for Tapestry has always been to create a web application platform so compelling that it would draw developers to the Java programming language, just to be able to use it. Of course, that's not so much a goal as it is... more »

I recently had the opportunity to present four different talks at the Enterprise Software Development Conference (or ESDC) in San Mateo, California. In an effort to provide additional data points and information, I created individual resource pages for each talk. These pages (hosted at my company’s site — beacon50.com) provide links to articles, blog entries, tutorials, and a copy of each presentation. If you’re curious to see what you missed at ESDC, then have a look,... more »

Szczepan has announced on the Mockito user mailing list that 1.8.3 of Mockito has been released. This released includes several small (but useful) additions as well as bug fixes.
The two parts of this release I like are the new annotations @Spy, @Captor, and @injectMocks. These add to the already useful @Mock annotation to simplify test setup tremendously. Additionally, the @Mock annotation is now configurable so you can add different Mock/Stub styles; previously @Mock only supported the... more »

Let’s start with some background.
I complained that Scala did not seem to be very functional to me, but I didn’t really know how best to express what was fundamentally wrong with it. I did know that if “functional languages have a fixed set of features” like Scala’s creator, Odersky, claims, then it wasn’t simply “first-class functions in there, function literals, closures”, “types, generics, [and] pattern matching”. Scala has... more »

A politician once mused
A free lunch is only found in mousetraps.
While this quote is amusing, it’s painfully true. In fact, the whole notion of a free lunch and its consequences was copacetically captured by Herb Sutter in an article entitled “The Free Lunch is Over: A Fundamental Turn Toward Concurrency in Software” that was published in Dr Dobb’s Journal back in 2005. In this well crafted masterpiece, Mr Sutter tore apart the misplaced belief that... more »

I’ll be giving a presentation at Lambda Lounge this Thursday on Behavior Driven Development With Jspec. If you’re in the St.Louis area come on by and learn about BDD and how you can use it to drive your design. I’ll be using jspec to demonstrate how to build a functioning feature for a javascript library driven by small, iterative examples.

I’m gearing up to put together a retrospective for my team at my current client site, and I’ve been both thinking about and reading over notes from previous retrospectives I’ve either sat in or facilitated. Looking over a lot of these notes, especially from the worst ones, I’ve noticed an emerging pattern of behavior that can either make or break a retrospective. Here’s a few that I think are the most important.
Retrospective Belongs to the Team

Been doing some fooling around with scala for a little bit tonight, and specifically been trying out the BDD framework specs. specs adds some nice stuff to mockito that makes it read like a natural language… and I like it!
Take this simple example of stubbing:
list.get(0) returns "yo"
Yep… that’s perfectly valid scala code… and totally awesome.
Want to verify that a method was invoked with a specific argument?
notifier.send(order) was... more »

Back in the Age of Aquarius, I wrote an article entitled “Use test categorization for agile builds” in which I attempted to delineate various types of tests and then went on to suggest how to categorize these various tests so as to get the most out of a build run (i.e make it fast and effective at providing meaningful feedback). Back then (and to an extent now) my concern was with test execution; that is, I like to categorize tests as fast and slow. Accordingly, I run the fast... more »

Or should that be "Late February of Progress". I have to say I'm a bit envious right now of Rich Hickey ... I can see that he's continuing on like a steam roller, extending and improving Clojure. I guess he's having some success in generating Research and Design budget from funding companies. I can see, following his threads, that he's working on yet more concurrency metaphors for Clojure, which is a good thing (though eventually there'll need to be a big book just to describe them... more »

As part of the Lambda Lounge, established by Alex Miller (Thanks!!), we have started a group to study the SICP. We just started and are going virtual... if you would like to participate, email or tweet me (@kensipe). In the process of studying SICP and LISP, I plan on focusing on Clojure. Clojure was previously on my machine as I was reading Stu's book Programming Clojure, however increased usage would require some maturing of my tools. This led to the discovery of Mark Reid's blog... more »

Last week, I spoke at the New England Java Users Group, one of the biggest and best around. I had a rocking good time, the audience was outstanding and Dave Klein (author of the outstanding Grails: A Quick-Start Guide) was even there! Anyway, one of the attendees, Deborah Hamill (VP Engineering at Accordare, Inc.), was kind enough to collect up all the links I referenced during the talk – including ones that weren’t even on my slides! Many thanks Deborah, I appreciate it. By the... more »

I just released the DynamicDomainProperties plugin for Grails, which allows domain classes to have dynamic properties. It’s pretty nifty, if I do say so myself.
Based on my frustration with the Grails plugin culture because of differing cultural assumptions about open source works, and based on my lack of appreciation for the promises of indirect compensation offered to me as an open source developer, I’ve decided to release it under the GNU-Affero GPL 3.0, which is like... more »
