ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

\

Install web development tools to Mavericks (OS X 10.9)

Strongly opinionated set of guides to quickly setup OS X Mavericks for web development. By default OS X hides stuff that normal people don't need to see. These settings are better defaults for developers.

I don't want: any sounds, annoying confirmation dialogs, hidden extensions, superflous animations, unnecessary things running like Dashboard, Notification center or Dock(Alfred/spotlight works better for me).

These are my opinions. Read this document through and pick up the good parts to your preferences.

System preferences

Shell scripts and one liners

Snippets, tips and tricks in no particular order. FOR ADVANCED USERS ONLY. Some of these one liners may be dangerous since they might delete files in loops. Please pay attention and make backups. :-)

Extracting a column from a text file

Extract the 10th column while skipping the first line:

awk -F ' ' 'NR!=1{print $10}' filename.txt

Local SSL websites on macOS Sierra

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on macOS Sierra, but they have been known to work in El Capitan, Yosemite, Mavericks, and Mountain Lion.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward the edit command to Sublime Text:

alias edit="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"

Searching for Files

Find images in a directory that don't have a DateTimeOriginal

exiftool -filename -filemodifydate -createdate -r -if '(not $datetimeoriginal) and $filetype eq "JPEG"' .

###Output photos that don't have datetimeoriginal to a CSV### Note this can take a long time if you have a lot of jpgs

Mac OS X 10.10 Yosemite

Custom recipe to get OS X 10.10 Yosemite running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.

This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.

You are encouraged to fork this and modify it to your heart's content to match your own needs.
