A few months ago, Let's Encrypt rolled out a feature to verify domains over
DNS. Their automatic configuration tool doesn't support all
the use cases yet, including my particular scenario: multiple load-balanced EC2
instances behind a single ELB, using Route53 for DNS. I wrote a
tool to simplify updating Route53 DNS Records with the
challenge, as well as updating the ELB with the resulting certificate. Check
out the README and code, or read
on for why I wrote it.

A movement has been growing over the last several months to make our Rails applications more object-oriented. One of the most popular recently has been Avdi Grimm's Objects on Rails. In it, he talks about an alternative to the Presenter pattern, which he calls Exhibits (and both of which are subsets of the Decorator pattern). I've been using another form of this, which may or may not be called a Conductor.

I was working on a script to sync hundreds of thousands of records
between two databases, and wanted a simple way to keep track of
progress. I couldn't find one that was easy to use and did what I
wanted, so I wrote my own. Not much more introduction needed, how about
a simple example?

After nearly a year on hiatus, I'm finally ready to start blogging again. I have several neat projects I've been working on over the last several months, and I need a place to write about them.

The adapter API for DataMapper has been in a bit of flux recently. When I submitted
my proposal for a talk at MountainWest, adapters were irritatingly complex to write.
You just needed to know too much about DataMapper's internals to be able to write one.
A week before the conference began, I started a significant effort to re-write the API to make
it easier. I succeeded, a little too well; my 30 minute talk only took 15. Since then,
I've written a couple more adapters from scratch, and refined the API further. This post
will serve as notes on the changes that I've made, and a tutorial on writing adapters.

I was just going to post a comment in reply to Adam Wiggins's Database Versioning post, but it ended up being pretty long, so I'll post a response here instead.

I recently came across a situation where I had an AbstractClass, an I wanted to know all of the classes that had inherited from it. There were lots of implementations on the web, but that weren't exactly what I wanted, or they used ObjectSpace to get ALL the classes, and see if the interesting one was in its ancestors.

Where I work, we have fairly extensive, JSON-based web services in all out applications. As a quick example, here's what you would get if you were to

Our app is very (JSON) web-service heavy, and so having helpful error messages in our web service documents is pretty important. Luckily, Merb makes this, like everything, a metric shitton easier than it is in rails. There are a couple poorly documented things I had to stumble through, so I thought I would write some up on how to do this.

In several of my pages, I have a side-bar menu-y thingie. I didn't want to have to rewrite a controller-specific layout each time, but luckily Merb supports something similar to Rails's content_for block that I wrote about earlier. In Merb, its done using

Had to google for quite a while before I was able to find the solution. Essentially, I have a model that I want to always use a different repository than what I
:default. To do that:
