So I developed a tiny command line client, which allows you to send request easily. It comes as a gem and easily to install:

gem install oauth-cli

After installation, execute oauthc. You either make onetime calls, with giving all required data as parameter, or just go into interactive mode, to get a shell for multiple calls and history. For not stating all connection data over and over again, it comes with multiple profile support, a wizard to create those easily and presets for Twitter and Qype.

See this nifty example call:
oauthc -p twitter get statuses/friends.json

Safari open always in tabs:

defaults write com.apple.Safari TargetedClicksCreateTabs -bool true

Safari enable Development mode:
defaults write com.apple.Safari WebKitDeveloperExtras -bool true
defaults write com.apple.Safari IncludeDebugMenu 1

Well, that’s it! Stay tuned for updated…

Some while ago I bought this nice Midi Controller BCD3000 by Behringer. It’s an easy to use device which brings way more fun mixing your MP3. For easy party playing mode I very like Djay, which is a simple but very powerfull mixing software. It now support Midi devices as well!
Unfortunately I couldn’t find any predefined Midi Mappings for Djay and BCD3000. So I created my own. Please download the file here. For now, all basic features are mapped, I may add sophisticated ones soon. It’s hosted on github, so please fork it and add you changes.

Happy DJing!

But Rainbowduino support improved as well. I fixed lots of bugs and implemented requested features. Now you can control the display brightness, save up to 10 frames onto the device and serial port is auto detected. In general, I defined an basic API to communicate with the devices, which allows you to add more devices easily (e.g. monome!). With that, all Rainbowduino stuff is moved in a separate Rainbowduino Processing library.

See official mtXcontrol project page for more.

Yay, I finally released my Launchpad Processing Library. Please see it’s project page and source at github.

Videos & more are coming soon. (Yes, this includes an updated mtXcontrol Version with Launchpad support!!)

See MacGPG and GPGMail for more…

UPDATE: btw. to get GPGP work with gmail, check out FireGPG, a nice plugin for Firefox, which works perfect for me on Mac OS X. Unfortunately I haven’t found any Safari solution yet…

For that, I needed Serial communication within ruby. Thanks to ruby-serialport first steps went quite well. I could write OR read from and to Arduino easily. But for some reasons, writing AND reading using the same instance didn’t work out.

I used a simple ‘send-input-back’ sketch on the Arduino side. So every byte I’m sending is returned back. I checked with the Arduino IDE Serialmonitor and a simple Processing script – everything worked alright. But using ruby it was different. Writing to serial port worked okay, but reading from it was just random. Sometimes I read the response, sometime I didn’t – really, really weird. Some headaches and a lot of time testing I finally found the solution: just open two instances of the serial port. One for sending, one for reading – and, surprise, surprise – it works perfect! Who would have guessed that!? Strange..

// To be completed
require 'serialport'
port_write = Serialport.new()
port_read = Serialport.new()

Ok, continuing hacking, more soon…

(*  small apple script to save rating into grouping field and
   vice versa. Perfect to persitent store your rating witin the file
*)

tell application "iTunes"
	repeat with stars from 1 to 5
		set rating_value to stars * 20
		set group_name to "" & stars & " Stars"

		set sel to (every track whose rating is rating_value and grouping is "")
		repeat with aTrack in sel
			tell aTrack
				set grouping to group_name
			end tell
		end repeat

		set sel to (every track whose rating is 0 and grouping is group_name)
		repeat with aTrack in sel
			tell aTrack
				set rating to rating_value
			end tell
		end repeat
	end repeat
end tell

Btw. for each Star rating I do have a smart playlist which allows me to find those quickly.

module Kernel
   private
   def this_method
     caller[0] =~ /`([^']*)'/ and $1
   end
end

for Ruby >= 1.9 you can uses this:

module Kernel
   private
   def this_method
     __method__
   end
end
