Interesting Object Methods in Ruby
This little Rubyism is something that I use frequently for debugging my objects. I add a method to every object to show only the interesting methods. What do I mean by interesting methods?

Stopping Curb From Segfaulting
While trying to get the curb gem up and running using Ruby 1.8.7p174, I kept getting segmentation faults. I Google’d around and really wasn’t able to come up with much other than lots of people saying not to use ports here. Since I don’t use Mac Ports, I use Homebrew, I figured this wasn’t an …
Creating Configuration Files With Ruby Templates
I recently had a very repetitive configuration file that needed creating. There were approximately 50 config blocks of 10 lines each with only the host name changing with each block. So I decided to take a shortcut and do it in Ruby using ERB templates. This is so easy and literally save me hours worth …
Using Unique Keys and Key Groups with Background Jobs in Gearman::Client
While diving into Gearman using Gearman::Client with MySQL and libdrizzle (I know, a mouthful), I ran into what I thought was a bug. I was only able to add 1 background job of any type at a particular time. The launchpad “bug note,” which is available in its entirety here, is rightly labeled won’t fix.
Multiple Input Locations From Bash Into Ruby
I have been trying to figure out how, while using OptionParser to be able to check for files being input on the command line and if they don’t exist, check other input streams (like Bash). This initially wasn’t very easy since input streams are blocking. So with a little help from friends (thanks roberto), I …
Should I Mock Kernel#exit
I don’t know what the right answer is, so any insight would be appreciated. From Googling around, I came across this thread on StackOverflow which talks about Validating exits and aborts in Rspec. I have a few issues with this, namely that I am using shoulda and I don’t want to validate the exit, I …
ColorTail Gem
One of the best ways to learn something new is to find a project in that realm and do it. I wanted to learn Ruby on Rails, so I wrote a web site. I wanted to learn Python, so I did a project in it for work. Now I want to get better at Ruby, …
Monitoring Services with Nagios::Plugin
There are a lot of people who say, “if it isn’t monitored, then it isn’t a service.” The problem is that I don’t think enough people outside of the systems world believe that or even understand why its said. I think the primary offenders here are developers. It isn’t because they don’t know better, but …
Database Read/Write Splitting in Frameworks/ORMs
Although one of the primary ideas behind frameworks is to keep things as simple as possible, sometimes they create issues in the long run. What I am about to discuss is something of a luxury problem (as scaling usually is), but it is a problem nonetheless. When initially starting a project, whether you are using …
Textmate Minimap Plugin
My editor of choice for most of what I do on the Mac (when I’m not in the shell using Vim) is Textmate. I recently came across a neat plugin called the Textmate Minimap. Essentially this plugin opens a map across the side of your Textmate window (like another drawer on the other side) and …
