# 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)

Save books out of Safari Books Online

From http://objectivesea.tumblr.com/post/9033067018/safaribooks

This is hard. I spent way too much time figuring this out, because I was annoyed that a book I bought (Addison-Wesley) was available online for free, except only for 45 days after which payment was required. So I made this hack... probably useful to no one else, but here it is.

Requirements:

1. iPad.
2. Safari To Go (the Safari Books Online iPad app).
