Earlier this year I started using RSpec and loved it immediately. Testing is not the most exciting or glamorous part of software development but a behavioural driven approach really appealed to me, as did the much more readable RSpec syntax. To get me started I bought the RSpec Basics screencast from PeepCode (which has since expanded into a 3 part series). It was a good introduction but, as is of
We’ve spent the last few weeks working on a new Rails app for a film and photography site and, as you might expect from my recent posts, we’re using Paperclip to handle file uploads. Without any more effort than a script/install of Paperclip we get thumbnailing of images and PDFs, but what about thumbnailing the video files that will be uploaded to the site? Enter FFmpeg. Installing FFmpeg In case
Way back last November when I first blogged about Paperclip I included a brief mention of hiding files behind a controller rather than simply putting them in the public directory for all to see. Since then I’ve noticed that the question of how to actually do this has come up regularly over on Rails Forum and a couple of weeks ago I had to figure out how to update some of our code to protect assets
Mislav’s will_paginate plugin (and Gem) has become the de facto standard for pagination in Rails, replacing the often derided classic pagination from the dark days before Rails 2.0. If you haven’t used will_paginate before then Ryan Bates’ RailsCast is a good introduction, although be warned that it is just over a year old and there have been a number of changes to the plugin in that time (the cur
Back in December I posted about ImageScience and RubyInline on Windows. Turns out I wasn’t the only one trying to get this combination working: according to Google Analytics it has become our second most popular blog entry (for the naturally curious this is the most popular). A man who knows a lot about Ruby on Windows is Luis Lavena and a day after I posted he very kindly took the time to compile
I've used VMware for many years to allow me to test and develop various server configurations and distributions. It's where I played with Linux-VServer, User Mode Linux (UML), Kernel Based Virtual Machine (KVM) and Xen. The relevent part to EC2 here is obviously that EC2 is also Xen based. So far when using EC2 I've stood on the shoulders of giants and taken existing AMIs and used them as they ar
For well over a year now attachment_fu has been my plugin of choice for adding file uploads to our Rails applications, but recently my fellow WebFellas have been raving about Paperclip from the clever guys at thoughtbot. As I’ve just started yet another new project I figured it was time to take Paperclip for a spin. The obligatory special instructions for Windows If, like me, you’re a long-suffer
Rails 2.1 has just been out a week and so far something that seems to have passed most people by is that it now includes much better caching capabilities, including built-in support for memcached. Last week I reached the point with an application where I needed to cache some models in memory to get a performance boost and decided to check out the current status of plugins like cache_fu and Cached
