MichalBryxi / sorted_hash.rb

Last active December 16, 2015 02:19

In ruby 1.8 you don't have option to serialize hashes sorted. You can find many monkey patches on the internet which allows this. Unfortunatelly there are numerous errors in them. I would like to keep here most bug-free version.

	class Hash # :nodoc:
	undef_method :to_yaml

	# Replacing the to_yaml function so it'll serialize hashes sorted (by their keys)
	#
	# Original function is in /usr/lib/ruby/1.8/yaml/rubytypes.rb
	def to_yaml( opts = {} )
	YAML::quick_emit( object_id, opts ) do \|out\|
	out.map( taguri, to_yaml_style ) do \|map\|
	keys.sort_by do \|k\|

Last active December 16, 2015 22:39

Rails ActiveRecord migrations enhanced by possibility to run PHP migrations. Useful when you use ActiveRecord migrations for your (PHP) application, but you also need to use your application sources code classes in the migration process.

	##### Our Migration class db/iw_migration.rb ######

	# IW_Migration adds possibility to run PHP migrations in classic
	# rails ActiveRecord stack. It will receive PHP class name which will be
	# executed instead of regular AR migration.
	class IW_Migration < ActiveRecord::Migration
	# This will hold for us PHP class name
	@migration_class = nil
	# This will hold for us caller stamp from it's filename
	@migration_stamp = nil

Ever wanted to know why your grok patterns does not work? This might help a little.

Logstash @fields.anything usage example. Documentation is not very explicit in this topic.

MichalBryxi / transfer_lvm_volume.rb

Created January 25, 2014 20:14

Ever wanted to transfer multiple LVM volumes from one machine to other? Ever tried it? It's not hard, but it requires a lot of (manual) steps.

	#!/usr/bin/env ruby

	# Ever wanted to transfer multiple LVM volumes from one machine to other?
	# Ever tried it? It's not hard, but it requires a lot of (manual) steps.
	# Things get especially annoying if you want to test it first and than
	# transfer everything ASAP. If you like to automate things, you can try
	# this script. It uses LVM2 snapshot mechanism, so in theory you don't
	# need to stop any service using the volume. Of course this will ensure
	# only LVM/filesystem-level consistency, not application-level sonsistency!

	# 1) This script
	# 2) Passwords-less sudo on destination machine
	# 3) Sudo rights on source machine

MichalBryxi / virtual_host.conf

	[06/05/14 23:49:20] Filip Rut: 000-default.conf *****<VirtualHost :80>
	# The ServerName directive sets the request scheme, hostname and port that
	# the server uses to identify itself. This is used when creating
	# redirection URLs. In the context of virtual hosts, the ServerName
	# specifies what hostname must appear in the request's Host: header to
	# match this virtual host. For the default virtual host (this file) this
	# value is not decisive as it is used as a last resort host regardless.
	# However, you must set it for any further virtual host explicitly.
	#ServerName www.example.com
