First, some context.

I urged the AltConf organizers to publish a Code of Conduct for their attendees and speakers. In that Twitter conversation, I repeatedly cited Ashe Dryden's Code of Conduct 101 + FAQ.

This is what they published on their website as their code of conduct (as of 2014-05-06):

AltConf is provided free of charge, on a first-come, first-served basis, without warranty or liability, by volunteers, for the good of our community.

To participate in our conference in any way (attendee, speaker, sponsor, etc), you must agree to abide by the instructions of the volunteers and the decisions of the organizers, and acknowledge that you may be barred from participation at any time, for any reason.

indexheaders/findheader

Ever wish you could do something like view $(findheader signal.h)—and have it be fast? Now you can.

(open -h is one alternative, but that opens it in Xcode, rather than a terminal-based or other editor.)

Basically, it's like “Open Quickly” for the command line.

New CPU Usage cache

Currently: Parallel C arrays of Cocoa text system objects, colors, etc.
	drawRect: looks up the objects it needs in those arrays, indexed by the CPU usage percentage, and creates and caches whatever it doesn't already have.
Problem: drawRect: has a slow path where the cache does not contain the needed objects yet, so it must create them. Even the check itself slows down every pass through drawRect:.

Solution: A single array containing blocks.
Initially, this would be filled with all the same block, each of which creates the needed objects, creates a block that captures those objects and does the drawing, and replaces itself in the cache with the new block.
drawRect: simply calls the appropriate block in the array, unconditionally. The slow-path block will move itself out of the way when it's no longer needed.
