Custom Signals in ruby-gtk2

 It cost me a bit of time to find this out so here is a summary ..

 In order to use a custom signal within gtk2 class there are three things which have to be done.

class SpecialButton < Gtk::Button

 type_register

  signal_new("changed",      # name

  GLib::Signal::RUN_FIRST, # flags

  nil,                     # accumulator (XXX: not supported yet)

  nil,                     # return type (void == nil)

  Integer                  # parameter types

  )

 def signal_do_changed(val)

    #puts "enter do_changed"

 end

  def initialize 

    # your special stuff here

  end

end 

 now you can use signal_emit("changed",value) within this class and signal_connect("changed"){ #method } on objects of this class

Apache 2.2.2 for Ruby Rails on Ubuntu 6.0.6 Server

In order to run the load balancing module in Apache in conjunction with a mongrel cluster a newer version of Apache is required then is available in the standard repositories.

I have created some deb packages which work for me which might be of use to others.

IMPORTANT!!! I am NOT using PHP or PERL so I have NOT created matching packages for these modules - you are on your own there.

In order to satisfy dependencies for the apt  mechanism I have created a dummy PHP deb package which keeps apt happy.

you can find these deb packages in the download section
