The Loop

Its taking some kicking around, but here is the fruit of my labour… using core foundation over the RC bridge.

require 'osx/cocoa'

loginItems = OSX::CFPreferencesCopyValue(
      "AutoLaunchedApplicationDictionary", 
      "loginwindow", 
      OSX::KCFPreferencesCurrentUser, 
      OSX::KCFPreferencesAnyHost)

application_path = File.expand_path("~/path/to/your.app")
application_hidden = false

loginItems << OSX::NSDictionary.dictionaryWithObjects_forKeys(
    [ application_path, application_hidden ], 
    [ :Path, :Hide ])

# puts loginItems

OSX::CFPreferencesSetValue(
    "AutoLaunchedApplicationDictionary", 
    loginItems, 
    "loginwindow", 
    OSX::KCFPreferencesCurrentUser, 
    OSX::KCFPreferencesAnyHost)

OSX::CFPreferencesSynchronize("loginwindow", 
        OSX::KCFPreferencesCurrentUser, 
        OSX::KCFPreferencesAnyHost)

With any luck this might help someone :-)

I’ve just been playing around with a few things and stumbled accross a really neat ruby lib called ‘timeout’. I used it to make a quick check for network connectivity like so:

require 'timeout'
require 'socket'

begin
  timeout(10) do
    TCPSocket.new("www.rubyforge.org", 80)
  end
    puts true
rescue
  puts false
end

For so few lines thats a really neat; I thought so at least! :-)

I just came across a great Scala presentation from JavaOne. If your not looking at learning Scala, then this presentation will give you a whole heap of reasons to get up and do something about it.

A friend of mine sent this to me – anyone working in IT will appreciate the funny side of this!!

My mind escapes me at this late hour on a Tuesday eve, but Im fairly sure i’ve blogged about the httperf tool from HP Labs before.

Anyway, if I havent, thats a different story, as today, I want to point you good reader to the wonderfull tool that is Bong

httperf has somewhat cryptic command syntax, and bong is a really nice wrapper around it which make leveraging the full power of httperf a breeze.

Check out the Bong home page for more info – I’ll put up a quick tutorial when its not so late and my brain is functioning properly.
