I'm planning on either writing this up in detail or maybe doing a screencast about screencasting, but I'll give a short version here.

On sound quality:

This matters a lot. In decreasing order of importance:

1. Remove echo. You have to hear this to understand. Set up a mic in front of your mouth and record a sentence. Then, put a thick comforter over you and the mic and say it again at the same distance. Listen to

Inside of Rails views, you can call partial views (any view file named with an underscore as the first character) like this:

render partial: "partial_name"

You can also pass local variables, which is fantastic to ensure that your views & partials don't try to access data you didn't specifically hand to them from the controller.

@tylerhunt showed me this week that it was possible to avoid using instance variables (which are copied from the Rails controller to the corresponding Rails views) altogether by passing local variables to the view.

Obtain P value from positive and negative Z scores

My fiancée is working on her master's thesis and her professor recommended a website that gives her P values when she plugs in Z scores.

The website works fine (although it crashes for a while on incorrect input) but it provides no transparency as to the formula used to compute the P value.

More problematic, she had to input hundreds of numbers into it which took forever. I tried to find an Excel formula that could replicate the results of the website

# This monkey patch modifies the RSpec `eq` matcher to suggest the `be_within`

Looks like your app's ./bin/rails is a stub that was generated by Bundler.

In Rails 4, your app's bin/ directory contains executables that are versioned
like any other source code, rather than stubs that are generated on demand.

Here's how to upgrade:

  bundle config --delete bin    # Turn off Bundler's stub generator
  rake rails:update:bin         # Use the new Rails 4 executables
  git add bin                   # Add bin/ to source control
