Desert Code Camp (Tempe, Arizona) - Josh Knowles (JoshKnowles.com) gave a speech on agile software development. Agile software development is a conceptual framework for software engineering that promotes development iterations throughout the life-cycle of the project. Agile methods also emphasize working software as the primary measure of progress. Combined with the preference for face-to-face communication, agile methods produce very little written documentation relative to other methods. Josh is a freelancer and an opinionated Rails developer.

Hi fellow code monkeys :) Today's episode covers Amazons Simple Storage Services (S3) and other important updates.

Driving while podcasting - sounds illegal but it seems like the only way I'm going to get a new episode online. I've been busy working on a new project and shared my experience with deploying my latest Ruby on Rails application on Media Temple's grid infrastructure. Here's the blog posts that I mentioned in the cast with tips and tricks for deploying on mt with svn and capistrano. http://blog.vixiom.com/2007/02/18/mt-ror-a-z-the-complete-guide-to-getting-rails-running-on-media-temple/ http://www.capify.org/upgrade/gotchas http://blog.postpostmodern.com/2006/11/29/a-recipe-for-capistrano-rails-deployment-on-media-temples-grid-server/ http://myles.eftos.id.au/blog/2006/10/27/setting-up-a-rails-app-on-a-media-temple-grid-server/

I had the opportunity of attending the Arizona on Rails user group this week hosted by Integrum. This episode is a presentation on Active Scaffold by Aaron Martin and Justin Walsh of Mega.Net.

ERB (Embedded Ruby)! This addition to our Ruby web server application allows you to call web pages with Ruby code that execute on the fly (time of render). Check out these snippets: myfile = IO.readlines("chris.html") #@session.puts myfile template = ERB.new <<-EOF #{myfile} EOF @session.puts template.result(binding)

This is a continuation of the BYO-WebServer application except rather than outputing static text, we will read and output an html file stored in the same directory. The new 2 lines of code are as follows: myfile = IO.readlines("chris.html") @session.puts myfile Tune in next week for some ERB!

By popular demand, here's a screencast of a basic web server engine based on Ruby. Source by Suresh Mahadevan. require 'thread' require 'socket' class RequestHandler def initialize(session) @session = session end def process while @session.gets.chop.length != 0 end @session.puts "HTTP/1.1 200 OK" @session.puts "content-type: text/html" @session.puts "" @session.puts "Hello World " @session.close end end server = TCPServer.new("0.0.0.0", "8888") while (session = server.accept) Thread.new(session) do |newSession| RequestHandler.new(newSession).process end end

This episode features a presentation by Jade Meskill, founder of Integrum Technologies (http://integrumtech.com) at the AZ on Rails User Group meeting from 6/19/07. Jade gave us a good walk through on Why's Camping framework.
