Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";
}

The Best of the Best Practices (BOBP) Guide for Python

A "Best of the Best Practices" (BOBP) guide to developing in Python.

A script to fix EDID problems on external monitors in macOS.

Install convmv if you don't have it

sudo apt-get install convmv

Convert all files in a directory from NFD to NFC:

convmv -r -f utf8 -t utf8 --nfc --notest .

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"

I have spent quite a bit of time figuring out automounts of NFS shares in OS X...

Somewhere along the line, Apple decided allowing mounts directly into /Volumes should not be possible:

/etc/auto_master (see last line):

#
# Automounter master map
#

+auto_master # Use directory service

	-- Save the foreground application
	tell application "System Events"
	set currentApp to name of 1st process whose frontmost is true
	end tell

	-- Get Lync in the foreground so we can use the menu
	tell application "Microsoft Lync"
	activate
	end tell
