Ruby 2.5: Not Blocking My Rescue
Rescuing specific exceptions excessively can cause problems, but if you've ever had need to rescue within a do/end block, you might have found yourself using wordy syntax. Ruby 2.5 has a solution for you. In Ruby 2.5, we’ll get a little syntactic sugar for handling exceptions inside do/end blocks. You can see the feature discussion on Ruby’s Redmine instance. If you’ve ever used the shorthand for rescuing inside a method… Continue reading
Ruby 2.5: yield_self
yield_self is coming to Ruby 2.5. What is this long requested feature, and how does it work? Some features take a while to get into a Ruby release. As you can see from the original request on Ruby’s Redmine issue tracker, yield_self has been brewing for 5 years. It has been waiting on a good name, and the Ruby team has settled on one. But what is it? To understand… Continue reading
Ruby 2.5: The Christmas Present
Let's talk a wee bit about Ruby 2.5. This starts a week of looking at upcoming features in the language. Here at FreeAgent Towers, we use a lot of Ruby. The application itself is written in Rails, and our website is static HTML, CSS and JS, but is generated with Middleman. We love it, and so we follow its development closely. One of the exciting points in the Ruby year… Continue reading
FreeAgent Testermonials: Getting rid of ‘QA’ and why what we call things matters
In this Testermonial post, FreeAgent's resident test engineer describes why we've rebranded 'QA' and why what we call things matters. As mentioned in my previous Testermonial, my only gripe when starting at FreeAgent — and a very minor one at that — was the rather entrenched use of the term quality assurance or QA in the development and release process to describe the pre-release testing phase which occurs before deploying… Continue reading

Schrodinger’s Ruby array
When can a single array instance in Ruby both be empty and contain items simultaneously? Read on, and find out! Continue reading
React Europe 2015
We love React here at FreeAgent. Our team has been using it heavily to build the mobile app, with very few issues. Because it’s so easy to use and helps with maintenance of complex UIs, we’ve also started migrating parts of the desktop app to it, such as inline bank explanations. At the beginning of July, a few of us went to Paris to attend the first React Europe conference.… Continue reading
Brighton Ruby 2015
Here at FreeAgent Towers we've always been proud of the fact that Scotland held the UK's largest Ruby conference every year since 2008 (back when it was called Scotland on Rails). The SRC organisers have hung up their conference boots for 2015 but fortunately there are other regional Ruby conferences getting off the ground. One of these is Brighton Ruby. A couple of FreeAgents were at the inaugural Brighton Ruby… Continue reading
Complexity will bite you in production
Here at FreeAgent we deploy updates to our app several times a day, and each deployment used to take between 10 and 15 minutes. This meant that if we introduced a severe bug into production and we needed to rollback, it would take us at least 10 minutes. This situation was not ideal, so we've been working to improve it. A quick look at our deployment process indicated that the… Continue reading
Upgrading to Ruby 2.1 (and other fun with YAML and complex regexes)
When we first launched FreeAgent, it ran on Ruby 1.8.6 MRI (and Rails 1.2!). We graduated to 1.8.7 REE when that became popular, then in the summer of 2011 we upgraded to Ruby 1.9.3. We've been running on that version (1.9.3-p194 to be specific) ever since. It has served us well, but performance is not one of Ruby 1.9.3's strong points and we've seen our application server response time gradually… Continue reading
