Moving Object-Relational Mapping to the Database
For anyone who has ever used Object-Relational mapping, you know that it's usually something done in fancy code libraries. You also know that such mappers are often slow and buggy. Next Wednesday, Portland Perl Mongers will be presenting a talk on Moving Object-Relational mapping into the database. This talk assumes you know databases, but even though the examples are in Perl, it's not really about Perl so you don't need to know the language.

However, if you've ever stumbled on the Object-Relational impedance mismatch, this talk will show you a powerful technique for minimizing this problem. Further, you start leveraging the true power of databases and gain a performance boost both for the application in terms of speed and the developer in terms of development time.

MySQL users are excused as it turns out that this "database" is still too primitive to support the techniques discussed (though it's finally getting there).

Agile 2005
Good morning! On the day after the close of Agile 2005 I'd like to congratulate our own Jim Shore on being one of two recipients of the inaugural Gordan Pask* award from the Agile Alliance. As explained by the alliance's Brian Marick, the award was created to recognize the contributions and accomplishments of "future leaders" of the Agile movement.  Jim has done yeoman's work on the FIT framework created by Ward Cunningham, as well as authored articles and experience reports from previous agile conferences, as was assistant chair for the Agile 2005 experience report committee.

* Although both Jim and Brian referred to "Gordan Pank", Brian made it clear at his speech at the conference that he was speaking of the noted cybernetician.  In the flurry of last-minute conference preparations and the overwhelming attendence, a typo or two can happen.

HP -- Invent what?
In case you still had any illusions about where HP is heading with the restructuring,  they fired Alan Kay. Inventor of Smalltalk, co-creator of the GUI, founder of Xerox PARC, Turing Award winner for his work on object-oriented programming.

Unbelievable.

Fit For Developing Software Released
Fit for Developing Software: Framework for Integrated Tests is the new book on Fit, written by Rick Mugridge with Ward Cunningham, has been released. It's available at either Amazon, ISBN 0321269349 or Powells, if you are in Portland.

My software-developer's appreciation for Fit comes from three areas of importance to me:
  1. Fit tests express business logic, as guided, or even written, by the business experts. They lay out the functionality as seen by the customers.
  2. The test fixture code itself belongs to the developers. By that I mean, they are not QC, integration or system tests. Developer ownership is a big win because in the process of writing fixture to pass the tests, developers come to understand the system better.
  3. Fit tests are larger in scope in than unit tests. While unit tests are critical in software development, they are not sufficient to ensure that the business functionality is implemented in ways that satisfy the users of the system.

This book has been called "two books in one", and I definitely agree. The first two parts are for customers and other non-programming team members. The latter parts are aimed at developers and have the technical topics. Ward said that as he and Rick were working on the book it started to get confusing, switching back and forth between the business-facing discussions and the technical discussions. Ward felt it best to cover the basics first, so they agreed to separate the book to speak to the two audiences one at a time. The resulting organization allows the book plenty of breathing room to address the needs of both audiences.

The "Questions & Answers" sections scattered throughout the book contain some of the most valuable gems. Here are a couple of examples related to ActionFixture:

  • From Chapter 10, p 73, "Some action rows have a keyword in the last cell. Is that optional?"
  • From Chapter 22, p 193, "Why does the actor have to be a subclass of fit.Fixture?
You'll have to buy the book to see the answers, though!

For my part, I am hoping to bring my own Objective-C implementation up to compliance with the 1.1 specification before the start of Agile 2005, where the community of Fit implementors is planning to congregate for a FIT Unification Summit on the last day of the conference.

Pacman
Here's to 25 years of running from ghosts while eating dots and power pellets. In 1999, Florida resident Billy Mitchell cleared every Pacman screen, ate all four ghosts with every power-pill and got every power-up and cleared all 256 Pacman screens, scoring 3,333,360 points. With one life.

Agile Development is not Rocket Science. Or is it?
The Lockheed-Martin Atlas V flight software team won the 2004 Better Software Innovation Award, in part by adopting agile methods. Best quote: "If a rocket, for whatever reason, should come apart in the air ... you can bet that our software will still be flying the biggest piece."

Google Summer of Code
The Summer of Code is Google's program designed to introduce students to the world of Open Source Software Development.

This Summer, don't let your programming skills lie fallow...Use them for the greater good of Open Source Software and computer science! Google will provide a $4500 award to each student who successfully completes an open source project by the end of the Summer. (payment details can be found in FAQ)

By pairing applicants up with the proven wisdom and experience of established prominent open source organizations (listed below), we hope to make great software happen. If you can't come up with a great idea to submit, a number of our organizations have made idea lists available.

April Meeting
April 13th, 2005 6:30pm at Free Geek, 1741 SE 10th Ave

Ruby on Rails by Lucas Carlson

Ruby on Rails (http://rubyonrails.org/) is a 9 month old web framework
that provides shortcuts to many aspects of web development. Many of you
have already heard of Ruby on Rails since a lot of people have been
proclaiming 10x increases in productivity recently. This presentation will
introduce you to the fundamentals of the framework by creating a simple
application from scratch. You will then learn some of the more advanced
features of Rails, like how to setup XML-RPC and SOAP API's for the
application and how easy it is to integrate Ajax features in forms. You
will also be exposed to some non-trivial Rails code from an existing
website (http://webcollaborator.com/) in order to judge how well Rails
holds up when implementing non-trivial concepts.

Knowledge of Ruby is optional, there will be a short crash course at the
beginning of the talk.

Lucas comes from a background of almost 8 years of PHP development. He discovered Ruby on Rails for himself 6 months ago and has been gainfully employed developing in Rails ever since. He has also made contributions to the framework. For more information about Lucas, see http://rufy.com/
