How to move to a fork after cloning
So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!
Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.
* Off the top of my head *
1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it
git remote add my-fork git@github...my-fork.git

This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…

A Django-Haystack backend for ElasticSearch 1.x that incorporates the best things I found in the recent master and pull requests, and fixes issues with each
"""
This is the basis for an elasticsearch 1.x backend I've cobbled together and am continuing
to refine and test for use. It's based on haystack master's version as of:
- https://github.com/toastdriven/django-haystack/blob/cbb72b3253404ba21e20860f620774f7b7b691d0/haystack/backends/elasticsearch_backend.py
But with @HonzaKral and @davedash's work to make the backend behave more like an ES user would expect with regard to doc types:
- https://github.com/toastdriven/django-haystack/pull/921
I also made a number of changes:
- I fixed bugs that I found in #921 (mostly related to mapping synchronization issues),
all of which I wrote up as comments on #921
