Install a new Ruby with rbenv on Mac OS (and make yourself a superhero)

If you're doing stuff with Ruby on a Mac, e.g. installling Jekyll or something, by default you'll end up having to use the sudo command to do stuff, since the permission to modify the default config is not available to your user account.

This sucks and should be avoided. Here's how to fix that.

Installing a new Ruby

To make this better, we are going install a new, custom Ruby. This used to be a big, scary thing, but thanks to the awesome tools Homebrew and rbenv, it's a snap.*

A word of warning: you will have to use Terminal to install this stuff. If you are uncomfortable with text, words, and doing stuff with your computer beyond pointing and hoping, this may not work well for you. But if that's the case, I'm not sure why you were trying to use Ruby in the first place.

PostgreSQL on Mac OS X

Install, and verify the installation.

$ brew install postgresql
$ postgres —help
postgres is the PostgreSQL server.
...
$ psql --help

psql is the PostgreSQL interactive terminal.

sass-px-to-em-converter

Diddy SASS helper to generate CSS in EMs when your designers specify pixels:

  // Helper to convert the designers' px specifications into EMs:
  // Eg: H2 { font-size: em(28px); }
  @function em( $px, $basePx: $baseFontPx ) {
 $px: $px / ($px * 0 + 1); // Strip off units to be sure we have a plain number. (eg: 20px -&gt; 20)

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file. Create a file called .gitignore in your home directory and add anything you want to ignore. You then need to tell git where your global gitignore file is.

Mac

git config --global core.excludesfile ~/.gitignore

Windows

git config --global core.excludesfile %USERPROFILE%\.gitignore
