Estimating how long it will take to develop software is difficult. Fortunately, as an industry we’ve moved away from big-planning-up-front, exhaustive Gantt charts and toward a more agile approach. Unfortunately, we’ve stuck with single point estimates which have some significant disadvantages when compared to range estimates.

Sanely Updating Your Gems
May 27th, 2011

If you followed my advice in the previous post, your Gemfile would look something like this:
source :rubygems gem 'rails', '3.0.3' gem 'devise', '1.1.5' gem 'redgreen', '1.2.2' gem 'capybara', '0.4.0'
There’s nothing wrong with this except that if you wanted to keep your gems up to date frequently it would be tedious to manually change all of these versions. Fortunately, we don’t always have to be this exact with the version numbers.

If you’re like me, most of the Rails applications you’ve written use tabbed navigation. And if you’re like me, you find that writing the code to handle tabs becomes increasingly more boring with each new application. So I wrote tabulous. Tabulous aims to solve this problem once and for all with a quick and easy way to set up and manage your tabs.
Roadmap for Learning Rails
July 24th, 2010

If you have no prior development experience, one of the worst things you can do when learning Rails is to just dive in. Some of the concepts build on each other, so jumping in would be like signing up for a calculus class before you’ve learned algebra. Sure, you could muddle through it, but most of your time would be spent trying to figure out why things aren’t working.

Back in November I participated in the CodeRack Rack middleware contest. Besides submitting entries that were stupid and downright dangerous I actually managed to create some middleware of value.
