Rails and the Legacy World

Posted

I gave what turned out to be a slightly controversial keynote at RailsConf. In it, I pointed out that people (like me) who can use Rails on green-field projects are incredibly privileged. We get to code using cool technolog more »

Migrations Outside Rails

Posted

I’m about 3 weeks into the rewrite of the Active Record chapters for the new Rails book. In the book, I try to demonstrate Active Record with real, live code. At the same time, I don’t want to ru more »

Decimal Support in Rails

Posted

A couple of blog posts ago, I commented on the dangers of converting database decimal columns into Ruby floats. And, five months early, Santa delivers. In the Rails trunk, numeric and decimal database columns with a more »

Pluvo

Posted

LtU has a link to Pluvo, a language which seems like a cross between Python, JavaScript, Ruby, and Lisp. It has some interesting ideas (coordination is a fun one) and the basic system (written in Python) is currently less than 50k to dow more »

Prices in Cents

Posted

In the second edition of AWDwR, I changed the Depot application to store money in integral cents, rather than floating point dollars and cents. Some folks pushed back on this, saying it overly complicated the application. This mo more »

Presentations

Ruby for Java Programmers

Ruby recently enjoyed its tenth birthday. Instead of cake and candles, the community celebrated by releasing a wave of new libraries and frameworks that make Ruby programming even easier. This talk features some of the best of these, as we explore Ruby. more »

Ruby on Rails

The Ruby on Rails framework has exploded onto the scene over the last few months. Propelled by some genuine benefits, and fueled by a whole lot of controversy, Rails seems here to stay. So, is it a Java killer? more »

Herding Racehorses and Racing Sheep

Are you frustrated by experts who can't tell you what to do, or by junior team members who refuse to see the big picture? How can you best develop careers: both yours and those of your teammates and managers? How can we learn to apply experience more effe more »

OpenSource Ecosystems

Open Source communities produce high quality software with little management and (typically) no pay. Most people looking at open source focus on using this software in their projects. more »

Using Ajax with Ruby on Rails

Ajax is becoming a requirement for new applications: it creates richer user experiences and more dynamic applications. However, doing Ajax by hand is difficult and error prone. The good news is that if you use Rails, you don't have to do Ajax the hard way more »

Testing your Rails Application

The Ruby on Rails framework has unit and functional testing baked right in. In this talk we'll see how easy it is to get started with testing in Rails, and we'll explore jut how deep the testing support goes. more »

Keynote: Cargo Cults & Angry Monkeys

What do aboriginal rituals and (somewhat mean) experiments on apes have to teach us about software development? More than you might think. more »

Dave Thomas By Dave Thomas

Ruby recently enjoyed its tenth birthday. Instead of cake and candles, the community celebrated by releasing a wave of new libraries and frameworks that make Ruby programming even easier. This talk features some of the best of these, as we explore Ruby.



We'll spend about half the session getting to know Ruby: the syntax, type system, blocks, iterators, and so on. Then we'll dive in and develop some real-world code using web services, RSS, and databases. If you want to come to the Rails talk, and you're not that familiar with Ruby, this talk is a good starting point.


Ruby on Rails

Dave Thomas By Dave Thomas

The Ruby on Rails framework has exploded onto the scene over the last few months. Propelled by some genuine benefits, and fueled by a whole lot of controversy, Rails seems here to stay. So, is it a Java killer? (No.) Is it a great way to develop certain classes of web application? (Yes.) Does it really deliver the 10-fold increase in developer productivity that some have claimed? (It depends...)



If you can't help thinking that there must be an easier way of developing web projects, come and join us as we construct an MVC-based Ruby on Rails application using the very latest libraries and tools. You'll get a taste of Ruby, and also a feel for some of the power and productivity gains offered by this remarkable framework. You'll need a grounding in Ruby to get the most from this talk; if you're not already a Ruby developer you might want to attend the Facets of Ruby talk before coming to this one.


Herding Racehorses and Racing Sheep

Dave Thomas By Dave Thomas

Are you frustrated by experts who can't tell you what to do, or by junior team members who refuse to see the big picture? How can you best develop careers: both yours and those of your teammates and managers? How can we learn to apply experience more effectively, and why do the many approaches designed to tame complexity actually end up increasing it?



Dave Thomas, of The Pragmatic Programmers, describes the solutions to these and other problems as he turns the Pragmatic Spotlight (and a good dose of twisted humor) on formal learning models, the Nursing profession, and streamlining sheep.


OpenSource Ecosystems

Dave Thomas By Dave Thomas

Open Source communities produce high quality software with little management and (typically) no pay. Most people looking at open source focus on using this software in their projects.



This talk takes a different tack: how can we bring the open-source way of developing software into our corporations, improving the way we write software? It turns out the answer has a lot to do with people, and a lot to do with agile software development.


Using Ajax with Ruby on Rails

Dave Thomas By Dave Thomas

Ajax is becoming a requirement for new applications: it creates richer user experiences and more dynamic applications. However, doing Ajax by hand is difficult and error prone. The good news is that if you use Rails, you don't have to do Ajax the hard way.



Rails has built in helpers that support Ajax development, and comes packaged with the powerful prototype.js and script.aculo.us libraries.

Come see how Ajax can be made to work with your Rails applications as we built a very dynamic ToDo list, and see how Ajax can be made robust with a simple calculator.


Testing your Rails Application

Dave Thomas By Dave Thomas

The Ruby on Rails framework has unit and functional testing baked right in. In this talk we'll see how easy it is to get started with testing in Rails, and we'll explore jut how deep the testing support goes.



We'll look at the basics: unit testing models and functional testing views and controllers. But we'll dig deeper, looking at the supplied mock objects and seeing how easy it is to add our own. We'll also investigate test fixtures, using them to generate both static and dnamic test data. Finally, we'll have a quick look at performance testing.
