# How to echobot with XMPP, BOSH, and Strophe
1. Setup ejabberd(http://www.ejabberd.im/) server and setup account admin@localhost.local
NOTE: localhost should be enough. If you setup something else, make sure you add it at /etc/hosts like this
#/etc/hosts
127.0.0.1 localhost.local
NOTE: Also download Psi(http://psi-im.org/), and make sure you can connect to your ejabberd server.
2. Download strophe(http://code.stanziq.com/strophe/) and place it (eg: /Users/makoto/work/sample/strophejs-1.0)
class AdminController < ApplicationController
before_filter do |controller|
controller.redirect_to login_path unless logged_in?
end

Created July 7, 2011 14:09
Rails migrations integer :limit option
literally always have to look up the meaning of :limit in migrations when it comes to integer values. Here's an overview. Now let's memorise it (oh, this works for MySQL, other databases may work differently):
:limit Numeric Type Column Size Max value
1 tinyint 1 byte 127
2 smallint 2 bytes 32767
3 mediumint 3 byte 8388607
nil, 4, 11 int(11) 4 byte 2147483647
5..8 bigint 8 byte 9223372036854775807
Note: by default MySQL uses signed integers and Rails has no way (that I know of) to change this behaviour. Subsequently, the max. values noted are for signed integers.

Use a generic client certificate with puppet

The problem

There's enough trouble with puppet's ssl model (mandatory client certs) that people go and do odd things to get around it. The primary problem is that for lab/preproduction environments, if you reinstall machines frequently, you lose access to the private key that generated the original cert but (absent some puppet cert --clean [node] operation) the cert still exists, leading to the dreaded Retrieved certificate doesn't match private key error.

A solution

Generate a single client certificate which all your nodes use, and have the master determine node names from facter rather than the SSL DN. This way you can re-install nodes with impunity and as long as your bootstrap plops down the correct config and the cert+key, you don't have any more SSL issues.

The caveats

If you have autosign turned on, this change represents a shift in security tradeoffs: you can turn off autosign and therefore more tightly control which clients can talk to your server because they need to have your clie
