How to use authentication subkeys in gpg for SSH public key authentication

GPG subkeys marked with the "authenticate" capability can be used for public key authentication with SSH. This is done using gpg-agent which, using the --enable-ssh-support option, can implement the agent protocol used by SSH.

Requirements

A working gpg2 setup is required. It may be possible to use gpg 1.4 but with gpg-agent compiled from gpg2. If you are using OS X 10.9 (Mavericks) then you may find the instructions [here][1] useful.

Whiteboard Picture Cleaner - Shell one-liner/script to clean up and beautify photos of whiteboards!

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Results

/**
* Transition helper that allows elements to transition from
* scalar sizes (e.g. "2em") to "auto" (or vice versa). This is useful because
* browsers either simply do not animate such transitions or do them poorly.
*
* Requires your CSS to already have the transition defined. This just allows
* it to function without much jankiness.
*
* Usage:

Instructions on how to fix npm if you've installed Node through Homebrew on Mac OS X or Linuxbrew

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
