Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

var Article = require('../../../models/article');

Those suck for maintenance and they're ugly.

Possible solutions

const responseTransform = requestURL => response => {
  // Original request url
  console.log(requestURL);
  // Deep clone from response
  const nextResponse = JSON.parse(JSON.stringify(response));
  // do what you want with response
  if (nextResponse.results_json) {
    nextResponse.results_json.search_results.map(r => {
      r.listing.name = '顆顆';

Open iTerm from finder

The code and instructions in this gist are from http://peterdowns.com/posts/open-iterm-finder-service.html. I've had to do this a few times and wanted to distill it the basics.

1. Open Automator
2. Create an Application
3. Choose Actions > Utilities > Run Applescript
4. Paste the contents of open_in_iterm.app into the window.
5. Save the script somewhere convenient
6. Find the script, then drag the script onto the Finder window while holding the command key (or in Yosemite, the command + option keys)

One can use MD5 or plain text diff to see differences in PDF files. If that's not enough, here's how to use diffpdf which knows how to diff based on appearance or words:

• brew install diff-pdf
• edit your ~/.gitconfig to add this:

[difftool "diffpdf"]
  cmd = diff-pdf \"$LOCAL\" \"$REMOTE\"
