                Bootstrapping - a list of useful resources to get up and running quickly
              
          
    Welcome!
UPDATE: This list is no longer maintained. I've moved it to its own repo so you can send suggestions as Pull Requests.
https://github.com/dideler/bootstrapping/
For feedback or suggestions, please send a tweet (@dideler). Gist comments don't notify me.
Pull requests aren't possible with gists (yet), so I don't recommend forking because then I can't easily get the change.
Starring this gist will give me an idea of how many people consider this list useful.

    Port Forwarding in Mavericks


Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

                Whiteboard Picture Cleaner - Shell one-liner/script to clean up and beautify photos of whiteboards!
              
          
    Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

## Makefile
# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

                Rich text / HTML editors and frameworks
              
          
    Strictly Frameworks


Mobiledoc - github.com/bustle/mobiledoc-kit - framework to build editors with a standardized JSON structure
ShareDB - github.com/share/sharedb - framework to sync any JSON document using operational transforms, add real-time collaborative editing to anything else
Bangle.dev - github.com/bangle-io/bangle.dev - toolkit built for building editors, based on prosemirror

Abstracted Editors

These use separate document structures instead of HTML, some are more modular libraries than full editors
