How to move a folder from one repo to another and keep its commit history
# source: http://st-on-it.blogspot.com/2010/01/how-to-move-folders-between-git.html
# First of all you need to have a clean clone of the source repository so we didn't screw the things up.
git clone git://server.com/my-repo1.git
# After that you need to do some preparations on the source repository, nuking all the entries except the folder you need to move. Use the following command
git filter-branch --subdirectory-filter your_dir -- -- all
# This will nuke all the other entries and their history, creating a clean git repository that contains only data and history from the directory you need. If you need to move several folders, you have to collect them in a single directory using the git mv command.

Things to commit just before leaving your job
// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.
//
// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

Python script to find the largest files in a git repository.
#!/usr/bin/python
# -*- coding: utf-8 -*-
# Python script to find the largest files in a git repository.
# The general method is based on the script in this blog post:
# http://stubbisms.wordpress.com/2009/07/10/git-script-to-show-largest-pack-objects-and-trim-your-waist-line/
#
# The above script worked for me, but was very slow on my 11GB repository. This version has a bunch
# of changes to speed things up to a more reasonable time. It takes less than a minute on repos with 250K objects.

Ray-AABB (Axis Aligned Bounding Box) intersection.
// adapted from intersectCube in https://github.com/evanw/webgl-path-tracing/blob/master/webgl-path-tracing.js
// compute the near and far intersections of the cube (stored in the x and y components) using the slab method
// no intersection means vec.x > vec.y (really tNear > tFar)
vec2 intersectAABB(vec3 rayOrigin, vec3 rayDir, vec3 boxMin, vec3 boxMax) {
vec3 tMin = (boxMin - rayOrigin) / rayDir;
vec3 tMax = (boxMax - rayOrigin) / rayDir;
vec3 t1 = min(tMin, tMax);
vec3 t2 = max(tMin, tMax);
float tNear = max(max(t1.x, t1.y), t1.z);

Exporting (iCloud) Keychain and Safari credentials to a CSV file

Exporting (iCloud) Keychain and Safari credentials to a CSV file

Update (October 2021)

Exporting password + one-time code data from iCloud Keychain is now officially supported in macOS Monterey and Safari 15 (for Monterey, Big Sur, and Catalina). You can access it in the Password Manager’s “gear” icon (System Preferences > Passwords on Monterey, and Safari > Passwords everywhere else), or via the File > Export > Passwords... menu item). You shouldn't need to hack up your own exporter anymore.

Original, Obsolete Content (2014)

After my dad died, I wanted to be able to have access any of his online accounts going forward. My dad was a Safari user and used iCloud Keychain to sync his credentials across his devices. I don’t want to have to keep an OS X user account around just to access his accounts, so I wanted to export his credentials to a portable file.
