[TIx 8] Weighted Random Sampling in Ruby

One of the many reasons I love working with Ruby is it has a rich vocabulary that allows you to accomplish your goals with a minimal amount of code. If there isn't a method that does exactly what you want, it's usually possible to build an elegant solution yourself.

Let's take the example of simulating the rolling of a die.

We can represent a die as an array of its faces.

die = [*?⚀..?⚅]
# => ["⚀", "⚁", "⚂", "⚃", "⚄", "⚅"]

Logging Rails 4 to Syslog, formatted w/ Logstash

Logging Rails 4 to Syslog, formatted w/ Logstash

Getting Started

Steps to get Rails 4 saving its output to Syslog via Rsyslog. This assumes you are on CentOS, but should be pretty adaptable to any other distribution. Ruby 2.0+ is also required.

  1. Add the gems lograge and logstash-event to your Gemfile. Feel free to remove from production if you'd like to test it in development as well or something.
  2. Update production.rb with the lograge settings and set the logger to Syslog::Logger.
  3. Add the conf files to /etc/rsyslog.d/. /etc/rsyslog.conf should have $IncludeConfig /etc/rsyslog.d/*.conf enabled, so it will load any additional configs from /etc/rsyslog.conf.
