Modules

WAL-E needs to be installed on all machines, masters and slaves.

How to install WAL-E

Only one machine, the master, writes WAL segments via continuous archiving. The configuration for the master postgresql.conf is:

archive_mode = on
archive_command = 'envdir /etc/wal-e.d/env wal-e wal-push %p'
archive_timeout = 60

Installing pdnsd from homebrew as root user.

$ brew install pdnsd

$ sudo chown -R nobody /usr/local/var/cache/pdnsd

$ curl -L http://goo.gl/kMlyQ -o pdnsd.conf
$ mv pdnsd.conf /usr/local/etc
$ sudo chown root /usr/local/etc/pdnsd.conf

	# send email using STARTTLS; Net::SMTP#enable_starttls requires ruby >=1.8.7
	# this hack is needed for rails <2.3; apparently >=2.3 has something for this already

	ActionMailer::Base.class_eval do
	private
	def perform_delivery_smtp(mail)
	destinations = mail.destinations
	mail.ready_to_send

	smtp = Net::SMTP.new(smtp_settings[:address], smtp_settings[:port])

	end

	compile with:
	gcc edid-decode.c -o edid-decode

	get EDID from IORegistryExplorer (mine, an old 24" Apple Cinema Display, is attached).

	Convert to binary with this command:
	ruby -e 'File.open("edid", "wb").write(File.read("edid.txt").split.map { \|s\| ("0x"+s).to_i(16) }.inject("", "<<"))'
