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…

Fix blurry fonts on some external monitors when using MacBook Pro Retina

How to fix blurry fonts on some external monitors when using MacBook Pro Retina

It seems that graphcis and fonts look rather blurry on some monitors when hooked up to a MacBook Pro (Retina). This might fix the issue for you:

  1. Download patch-edid.rb from http://embdev.net/attachment/168316/patch-edid.rb

  2. Execute in Terminal (without the $):

    $ ruby patch-edid.rb

  3. Copy produced folder (example: DisplayVendorID-22f0) to /System/Library/Displays/Overrides (authorize if needed, if the folder exists, backup it before)

A Simple Git branching model

a simple git branching model

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

All the cool animation curves from `CAMediaTimingFunction` but not limited to use with CoreAnimation. See what you can do with cubic Bezier curves here: http://netcetera.org/camtf-playground.html To get started just "Download Gist", throw the .h and .m files into your Xcode project and you're good to go!

Git Submodules basic explanation

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

  • Separate big codebases into multiple repositories.
