This week I launched a new site for The Scrum Training Institute at scrumtraininginstitute.com. If you’re getting started with Scrum or Agile these are the experts you want to learn from! Currently their team consists of Jeff Sutherland (co-creator of Scrum), Jens Østergaard (a fellow dane), Gabrielle Benefield and Pete Deemer.

Working with them has been just great. As a developer I just love having clients, that unasked will send me emails going:

Jesper, here’s the story:
As a customer, I want to be able to…

The site is live now and we will be adding more features over the coming weeks, as I work my way through the backlog.

If you are running the just released Rails 2.1.0 and have disabled ActiveRecord, you will likely run into problems launching script/server.

The culprit is the new config/initializers/new_rails_defaults.rb, which should test to see if ActiveRecord is loaded.

The bug report is here and the patch “AR can be disabled, new_rails_defaults.rb should check” has already been applied.

It’s a very tiny patch, so until the next Rails release is out, you can easily apply the patch manually.

Atlantic Dominion Solutions has posted a JRuby on Rails screencast. It is based on their excellent first JRuby tutorial, Get JRuby onto the Rails on Mac OS X.

Someone told me that watching a video is more fun that reading something. So much for the library I have sitting here then. However, in that spirit, we are happy to release the first in a series of screencast tutorials.

Also, while you’re there make sure you check out part two of their JRuby tutorial: Deploy Your First JRuby on Rails App to Glassfish.

Just found a very nice article, Tips for Optimizing Rails on Oracle, on OTN (Oracle Technology Network). Definitely worth reading if you are working with Rails and Oracle:

In this article you dug a bit into how connections to an Oracle database are configured in a Rails application, and you have seen how the framework has been updated in the 1.2 release to have better performances thorough the use of the cursor_sharing and prefetch_rows parameters (while waiting for a real bind variable implementation).
 
You have also examined the Rails migration commands that are relevant to tuning the database (specially creating/removing indexes).
 
Finally, as you’ve learned, a good understanding of both how Rails builds the SQL from the code and how the database executes them is needed to get the best performance. The provided plugins should help here.

I’m tumbling my notes from RailsConf at railsconf07.productive.dk.

Yay! Just bought my ticket for RailsConf 2007 today. Apparently tickets are going fast, so hurry up if you want to go.

I signed up for the conference and tutorials, so I’ll be in Portland from Wednesday evening through Sunday afternoon—probably missing the last keynotes since there doesn’t seem to be any flights back home later than 4 pm.

For a while I was planning on going to RailsConf Europe in Berlin instead, but after adding up the cost of going to Portland (conference fee, flights, hotel) I was surprised to find that it looks like it’ll be cheaper than last year trip to JAOO—which is just a 3 hour drive from where I live! But then JAOO prices are pretty steep.

Leave a comment or give me a call if you want to meet up in Portland.
