The gtalkbot code is reasonably simple as well when you take into account that it has to connect to the Google Talk instant messaging network. If you re not interested in the bot engine, then feel free to skip this section and move on to the next. The code is a little long as well, so we ll try to cover the important points without getting too bogged down in the details. The first block of code is the documentation comment for the Python script and the import of the various Python libraries needed to implement gtalkbot: #!/usr/bin/python2.4 # # Copyright (c) Michael Still 2006, released under the terms of the GNU GPL v2 """gtalkbot.py -- a modular Jabber bot This is a simple Python Google Talk and Jabber bot. It loads modules from the specified module directory, and then lets them register "verbs." These verbs are simple single-word commands that must be at the start of the line entered by the other side of the chat conversation. If the first word of one of these lines matches a registered verb, then the relevant module is handed the verb, as well as the remainder of the line (in separate arguments). The bot authenticates clients before it lets any verbs be executed. This code is very heavily based on the echobot example from the PyXMPP distribution. """ import sys import logging import locale

In the end, our activation code is merely a hash of the randomized version of the current time stamp. Now, we just need to make sure that our new make_activation_code method is called whenever we create a new user, so we ll add another filter for that. Scroll up to the top of the model, and add this line after the validation method calls: before_create :make_activation_code Even though we re not really set up to create a user using the sign-up form just yet, you can see the activation code being generated by creating a new user via script/console in sandbox mode: ruby script/console -s Loading development environment in sandbox. Any modifications you make will be rolled back on exit. >> u = User.new(:login => 'test', :email => 'test@test.com', :password => 'test', :password_confirmation => 'test') => #<User:0x2370160 @password_confirmation="test", @password="test", @new_record=true, @attributes={"salt"=>nil, "activated_at"=>nil, "updated_at"=>nil,"crypted_password"=>nil, "activation_code"=>nil, "remember_token_expires_at"=>nil, "remember_token"=>nil, "login"=>"test", "created_at"=>nil, "email"=>"test@test.com"} >> u.save

You can use xine to view digital TV broadcasts. In the controls, you ll see a button labeled DVB (which stands for Digital Video Broadcasting). You ll want to click this. However, you need to use an external utility to change the channel. These are scan and tzap. If you are using a DVB-S card, it s szap. For DVB-C, it s czap. You will need to install the dvb-utils package to get these programs. You first want a frequency file. You ll find quite a few in /usr/share/doc/dvb-utils/ examples/scan/; you can probably find one for your area. If not, it s easy to create one with the frequencies most likely listed on the website of the regulator in your area. You can now run scan to generate a channels.conf file: $ scan /usr/share/doc/dvb-utils/examples/scan/dvb-t/au-canberra > channels.conf After you ve run scan, you can now create a directory under your home directory called .tzap, .szap, or .czap (depending on what s appropriate for your card). You should copy the channels.conf file there. To change the channel, you use the zap utility (that is, tzap): $ tzap "ABC" You should now be able to use xine and the DVB button to view the MPEG-2 stream that is being broadcast. If you cannot tune in a TV station, your aerial might not be connected properly (or might not be adequate for digital). If you re really unlucky, like Stewart was, the TV card you have is a newer (incompatible) revision of a model that has previously worked OK, and the driver didn t give you any error. If you re slightly luckier, there might be an error in the log. Check the output of the dmesg command for some hints.

In this chapter, you re going to build a music system from the ground up in Ruby. The goals are (of course) to use Ruby, make getting started easy, and keep it simple enough for users to extend. Music theory is, alas, beyond the scope of this chapter (and I m not the guy to teach it anyway). But hopefully this will be enough to make you dangerous. You can always learn the rest later.

Music is just sound waves, and computer music is no different. But the vocabulary of sounds isn t necessarily the best vocabulary with which to describe or compose music. Directly controlling sound wave synthesis does unlock the full range of musically possibility, but most of the time it s just overwhelming.
