Computing Thoughts
Newsletter #58

This edition of my occasionally-published newsletter, which also goes out by email, covers upcoming events and the status of various projects.



TurboGears Jam, January 14-16, Ann Arbor, Michigan

TurboGears is a Python-based web application framework that was developed in Ann Arbor. We'll have a fascinating 3 days working on apps, along with Kevin Dangoor (creator) and Mark Ramm (TurboGears book author).

You can drop in at any level of experience, from beginner to expert. This is a free-form, collaborative workshop.

Keynote & sessions, CodeMash, January 18-19, Sandusky, Ohio

CodeMash is a developer conference geared toward bringing together developers of all types to learn from one another. It's at an indoor water park in Sandusky, OH and should be a lot of fun (apparently they have perfect waves that you can surf on, something I haven't done for years). The speakers will talk about Ruby on Rails, TurboGears, Java, .NET, Python, PHP, and more. I will be giving a Keynote called "The World is Dynamic" which I hope will make you think differently about what you do. I will also be doing several sessions, including moderating a panel on programming languages. Neal Ford, Scott Guthrie, and Brian Goetz will also be giving keynotes. It costs $99 for the 2-day confererence, but the early bird pricing ends on Monday, Dec. 18. That's also when the hotel will release the block of rooms (and the $88 nightly rate will go up to $150).

The Thinking in Java OpenLevel™ Seminar, January 22-26, Ann Arbor, Michigan

For the longest time I've felt like the traditional "eyes-forward" style of seminar is suboptimal. For one thing, research has shown again and again that lecturing is not a particularly effective way of transferring information. And that kind of seminar tires me out, so I resist doing them -- and I consider this a good sign that something should change.

So I've created the OpenLevel™ Seminar (my term), loosely modeled after the OpenSpaces concept. People work on exercises of their own choosing, at their own pace, with help as needed. Groups will form, and the unique format allows the class to serve beginning to advanced students in Java 5.

The JavaPosse Roundup, March 6-9, Crested Butte, CO

The JavaPosse is a very popular podcast dedicated to the Java Language, delivered by four Java experts: Tor Norbye, Carl Quinn, Dick Wall and Joe Nuxoll. The JavaPosse is one of the most effective ways that I keep up on Java news and developments (usually while driving).

You can find out more and get the podcasts here.

We've decided to do an open-spaces style conference in Crested Butte, focused on "Java on the Desktop," (that's just the main theme; any topics that someone wants to do a session on are fair game.

We'll have sessions in the morning, ski in the afternoon, then have informal evening time for dinner, discussion, etc.

The conference is limited to 70 attendees, and you'll need to get lodging ASAP, so don't wait!

Hands-On Java CD

With a move to another server, the sales system for this broke and hasn't been fixed yet. I apologize to those of you who have been frustrated by this. I'm in the process of moving to a Paypal-based order system which should be quicker to implement and more reliable.

The fourth edition of the CD, promised in the fourth edition of TIJ, has been languishing on the back burner for awhile.

Thinking in Java 3e and TIC++ V1 Solution Guides available

The server move also broke the sales and delivery system for these, but I've recently resurrected them via, a service I've been quite happy with so far.

Thinking in Java 4e Solution Guide

This is in the process of being copyedited, after which a couple of technical passes will be made. Because of the new sales and delivery system, it will be available very quickly once it is done.

OO Design Consulting

Consulting can be tailored to your needs. My particular interest is in providing object-oriented design assistance, where I work with your team to discover or refine your requirements and to develop a domain model for your system. In the process, your team learns how to tackle object- oriented designs while working on their own project.

I've been having very good success by working with your development team to quickly capture stories and create the domain model, then test the validity of the model and further develop it by rapidly implementing it in Python. By using a lightweight language, we can effortlessly make changes to the implementation and domain model; if the implementation is in a heavyweight language there tends to be resistance to design changes. This approach produces the best domain model in the shortest time, and allows a faster and more confident transition to your target language because fewer surprises happen once the domain model is shown to be satisfactory.


My current plan is to transform all my training courses into the OpenLevel™ format.

Seminars on DVD

It's been a slow process capturing two seminars, turning them into DVDs and getting them ready to sell. I will announce new developments first in the weblog and on the web site, and later in a newsletter.
