Just one type of test

ruby test/functional/person_controller.rb

Use some basic regexp

ruby test/functional/person_controller.rb -n /that_one_end_point_name/

Note

class Array

  # find_insert_index -> returns the index that the value should be inserted into
  #                      to keep the array sorted
  # Arguments
  #  val     ->  any sort of value that supports comparison or...
  #  &block  ->  If you want to compare a specific field on your object you could:
  #                {|x,y| x.FIELD <=> y.FIELD }
  #              or you could sort reverse:
  #                {|x,y| y <=> x} NOTE: your review must be sorted desc. for this to work.

Why?

Having to remeber what the boot2docker ip address sucks, wouldn't it be better to access it like localhost?

You can!

First you need to get the boot2docker ip address. You can get that in terminal:

$ boot2docker ip

On my computer I get:

What

Automtically configure tab name in Terminal.app when ssh-ing to a server. You can use any shell commands you want to get the desired output.

Why

I work on external servers 8 hours a day M-F and more likely than not I have multiple ssh sessions at the same time to the same sever under different users. It became a bit of a pain to have to rename the tabs everytime I logged on to a server. I just wanted that to happen auto-magically.

I searched the interwebs and came across this CNet article which had about 99% of what I was looking for. However, it never really mentioned how to modify the script to insert your own formatting. It didn't even mention adding it to your $PATH! So after a few minutes of messing with it I got something quite reasonable. I thought I'd share the results.

How

iamatypeofwalrus

 
# Official docs are a _bit_ light on specifcs
# http://ruby-doc.org/core-2.0.0/Kernel.html#method-i-set_trace_func
#
# There are other options if you are interested in a general trace:
# * ruby -r tracer your_script.rb
# * https://ruby-doc.org/core-2.3.0/TracePoint.html
#
# What I'd like to be able to do is create a helper module / class that can be added to any class like so:
# 

iamatypeofwalrus

# Run and fail
#   AWS_ACCESS_KEY_ID=*** ruby connection_pool_issue.rb
#
# Does not crash
#   empty_connection_pools_after_fork=true ruby connection_pool_issue.rb
#
# Hypothesis:
#
# the Aws SDK maintains a ConnectionPool in Seahorse. After fork
# file descriptors are shared between the parent process and any child processes.
