/etc/kde4/kdm/Xsetup

/usr/bin/killall synergyc
sleep 1
/usr/bin/synergyc <servier-ip-address>

/etc/kde4/kdm/Xstartup

/usr/bin/killall synergyc
sleep 1

merb’s provides/display in rails

DHH posted about merging merb’s provides/display into rails. He proposed used a dual of respond_to and respond_with, similar to merb’s provides/display, with a couple tweaks to allow each action to respond to different types. There are a couple things about the API he suggested which I don’t love:

• I don’t like the way respond_with(@deals, :to => [:html, :json, :xml]) reads, why not flip that around and do respond_to(:html, :json, xml, :with => Deal.new). This would work very well with how the current responds_to method works in rails, just adding an :with option to allow converting that object instead of rendering a partial. (see the index action below)
• When using the class-level respond_to, we could use respond_to(:with => Deal.new), or keep an alias of repond_with(Deal.new) (see the new action below)
• It would be nice to have an easy way to use the defaults for some response types, but allow customization for others. (see the create action below)

class DealsController < SubjectsController
  respond_to :html, :xml, :json

  def index
    @deals = Deal.all
    respond_to(:html, :xml, :json, :atom, :with => @deals)
  end

  def new
    respond_to(:with => Deal.new)
    # uses the class-level defined response types (html, xml, and json)
    # maybe this is a good case for also having respond_with(Deal.new)
  end

  def create
    @deal = Deal.create!(params[:deal])
    respond_to(:xml, :json, :with => @deal) do |format|
      format.html { redirect_to @deal }
    end
  end
end
