Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

strzibny

#!/usr/bin/env ruby
# Extracted from traceroute gem + checking the presence of views as well

require_relative './config/environment.rb'

class Traceroute
  def initialize(app)
    @app = app
  end

Adding an audit log to your Rails app

If you have any sort of administrative interface on your web site, you can easily imagine an intruder gaining access and mucking about. How do you know the extent of the damage? Adding an audit log to your app is one quick solution. An audit log should record a few things:

• controller entry points with parameter values
• permanent information about the user, like user_id
• transient information about the user, like IP and user_agent

Using the Rails framework, this is as simple as adding a before_action to your admin controllers. Here’s a basic version that I’m using in production.

keys = [
  %w[a 1 x],
  %w[a 1 y],
  %w[a 2 x],
  %w[a 3 x],
  %w[a 3 y],
  %w[b 3 y],
  %w[b 4 z],
]

Chances are your head's spinning right now. That accusation of bias caught you off guard, you got kind of defensive, and now all hell has broken loose. You're feeling attacked on all sides. You're a good person at heart, and having all these people treat you like the antichrist is pretty upsetting.

You need to say something, but you're probably not in the best headspace to write copy right now. So to help you along, here's my 100% guaranteed-or-you-money-back scandal defusement apology template:

On undoing, fixing, or removing commits in git

A git choose-your-own-adventure!

This document is an attempt to be a fairly comprehensive guide to recovering from what you did not mean to do when using git. It isn't that git is so complicated that you need a large document to take care or your particular problem, it is more that the set of things that you might have done is so large that different techniques are needed depending on exactly what you have done and what you want to have happen.
