Git Archaeology
April 22nd 2020 | Tags: git
Recently at work we passed a major milestone on our codebase, and I wanted to see if I could run some analysis over time on authorship and see how long some early contributors' work stuck around in the product.
A bit of experimentation and random googling left me with these three scripts.
Git Rebase by Example
June 20th 2017 | Tags: git
Today at work, I determined that my current work in progress branch was going to want to be merged into production ahead of our next scheduled merge/deploy of master. To make it easier to merge into our production branch for a hot-fix deploy, I want to have the branch based off production instead of master.
Building an Object Graph in Rails
June 4th 2015 | Tags: ruby rails
I was needing to do some object cleanup in our rails app the other day, and purge some malformed objects, so I put together a quick script using some ActiveRecord reflection to walk the object chain.
No More Bundle Exec
September 6th 2012 | Tags: programming ruby
Bundler is pretty darn good. Installing all your gems globally sucks. bundle install --path does a great job of fixing that but it means you need to bundle exec any shell commands you want to run, which again sucks. There are lots of attempts to fix this, but they're all fairly convoluted.
I'm a fan of simpler solutions wherever possible. I use zsh as my shell, which has a handler you can hook into if the command you're trying to run is not found. It's a simple matter to hook that into a custom...
Joining Git Repositoires
May 15th 2012 | Tags: git
At work, we provide an API for our app and maintain web-based documentation for said API. We originally had the documentation in a separate git repo, but as it makes much more sense to maintain the docs directly alongside the code it documents we wanted to merge the two repositories. This was done in two steps.
Moving files
First, we need to prep the docs repo such that the content is in a
reasonable location, rather than the root directory. This is done fairly
easily with git filter-branch
Parsing JSON in SQL
November 19th 2011 | Tags: ruby rails sql
The Problem: You have a database column with some data serialzed as JSON in it that you'd like to pull out into its own column to index it.
The Solution: Run a data migration to pull the value out. Table has 5 million rows and you don't want to round trip all that data through ActiveRecord? Just parse the json directly with some SQL:
