“Pull” has an ‘l’ in it.

“Push” does not.

$ g pul git: 'pul' is not a git command. See 'git --help'. Did you mean one of these? pull push

Errors in Public Libraries

A random anecdote about other people's code.

We had a stack trace recurring with high frequency on our management hosts today. Digging into the issue, we found this (cleaned up) trace:

The dynamic test anti-pattern

Branching and configuration belie uncertainty.

Quick RSS Validation

If you're using Ruby and RSpec with RSS you can save a lot of quick checking time by using functional programming.

After loading in the RSS feed, you can use the following transforms on the data:
