Stuff I wish I never needed to write.
Best OS.
An OS X launch daemon that remounts all volumes with noatime.
A slightly janky OS X program for simulating keystrokes. Useful for hacks.
A Safari extension for unscrewing Google and Facebook links. It used to be necessary to keep Safari history sane, and might still nix a bit of Google & Facebook tracking.
A ~/Library/LaunchAgents agent that periodically closes excess Finder windows.
A script to upgrade MacPorts ports. The primary feature is mounting a ramdisk to build on.
An OS X ~/Library/Services script to remove the quarantined xattr from files & directory trees. Useful for mollifying Gatekeeper by removing the "downloaded" stigma from .app bundles.
Rather, "not just OS X".
A script that reconfigures Linux qdiscs to a particular configuration, that throttles outbound nginx traffic.
A script for manually tiling X windows. You bind various invocations of the script to hotkeys to send the frontmost window to a particular subdivision of the screen. Works for xfwm4 (i.e. XFCE) and possibly others.
More-or-less cross platform rc file. Pretty old school, and mostly not zsh specific.
