Topics
First Session : Active Object by David Kemp

http://en.wikipedia.org/wiki/Active_Object

It will have a lot of overlap with a talk I gave several years ago on
“Futures”, but I figure I can make it sufficiently different to not
bore those that attended that talk.

I will even try to give a couple of examples in Ruby to perhaps
attract some Ruby lovers along

Second Session : Jaxer: The Javascript server by John Sherwood

‘Is it any good and when would I use it?’ – Come find out!

John Sherwood is doing a talk on “Replace Type Code with Class” from http://www.industriallogic.com/xp/refactoring/typeCodeWithClass.html

Martin Ellis is doing a talk on “The Shibboleth System, a standards based, open source software package for web single sign-on across or within organizational boundaries.”

Next Meeting (Wednesday, June 4th at 6:45 pm)
First Session (Refactoring to Patterns):

“Extract Adapter / Unify Interfaces with Adapter” by Ben Marsh

Second Session:

“The Pecha Kucha of javascript” by James Ladd
James would be showing us javascript syntax and the contrast same with other languages like Ruby, Smalltalk and Java.

Last month’s meeting was cancelled due to the crazy weather we had.
Next Meeting : Wednesday, May 7th @ 6:45pm
Location: ThoughtWorks Office, 155 Queen Steet, Level 11, Melbourne 3001

First Session (Refactoring to Patterns) : Replace Conditional Dispatcher with Command

Second Session: How to use Google Maps in your application by Krishnan Ramanathan

Firstly, Thanks for last month presenters – Geoff Burns and Gian Lorenzetto

Geoff spoke on “Move Accumulation to Collecting Parameter ” . The example used in the discussion was based on book example around replacing string concatenation with well composed methods which accumulate the result using a string buffer. We had some interesting discussion contrasting Collecting Parameter against the Visitor.

Gian did a great job of reviewing Kent Beck’s recent ‘Implementation Patterns’ book. The book contains lot of anecdotes and
paragraphs about good development practices often at a method level. The book seemed to lack code examples or diagrams often assumed to be present in a ‘Patterns’ book. But the paragraphs seemed thought provoking and often had to be read several times to grasp the thinking behind it. Overall Gian recommended the book to everyone.

Next Meeting – March 5th

First Session: Replace Implicit Tree with Composite / Replace One/Many Distinctions with Composite by Andy Bulka

Second Session: Realize the Interpreter through Selenium – David Kemp
David will be walking us through the selenium source code and illustrate its use of the Interpreter pattern.
