By the time I was working at Qype, I often had to deal with OAuth APIs. Doing example request works to a certain point quite good with a Plugin the for Firefox. But when it comes to Authorized or POST Request you’re stuck!
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

BCD3000 Djay Midi Mappings
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!
Rainbow Cube - here it is!
Yay, I finally got my Rainbow Cube from Seeedstudio. It came in various parts which required happy soldering. Now, I can start experimenting and porting mtXcontrol to support Rainbow Cube as well - stay tuned!

mtXcontrol meets Launchpad meets Rainbowduino
That’s it! I just released mtXcontrol version 1.1 with lot of updates and improvements. One major improvement is full support for Novation Launchpad: just draw your sequences and display them on your Launchpad! Even better, push the buttons to change the color, add, remove, copy & paste frames. For that mtXcontrol makes usage of the Launchpad Processing library which I released some days ago.
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.
Here it is: Launchpad Processing lib!
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!!)
Hacking the Nabaztag
Alright, I spend some time with my new toy Nabaztag ‘Nabaccia’
What confused me most: there have been two Firmware version out there. Some project depend on the old one, some other on the, new Jabber based, version.
Here are some interesting projects I’ve found:
http://nabaztools.sourceforge.net/ (outdated, MAC OS X)
http://sourceforge.net/projects/opennab/ (PHP)
http://code.google.com/p/nabazlib/ (python)
http://nabazlab.sourceforge.net/index_en.htm (windows only)
A working Proxyserver: jNabServer

GPG - up and running with Snow Leopard and Mail.app
Ok, I finally managed to set up my GPG Mail System. Thanks to the latest version of GPGMail and gpg (1.4.10) (via macports
sudo port install gnupg
) it’s running fine and smooth again with Snow Leopard and Mail.app. Perfect!
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…
If your ruby serial port doesn't read what' you're sending...
Some days ago I got my Novation launchpad an immediately started hacking with some Ruby and Arduino flavor. I wanted to port ccb23 Raindrops Project to launchpad.
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..
[ruby]
// To be completed
require ‘serialport’
port_write = Serialport.new()
port_read = Serialport.new()
[/ruby]
Ok, continuing hacking, more soon…
How to sync my mp3 Songs rating in iTunes across multiple Libraries
By now, I havn’t find any good solution to share my mp3 across multiple systems and disks. I’ve some on my local machine, some at work and some on my external harddisk to archive. Luckily, when copying my tracks to another library duplicates are ignored. But what annoys me most is that my ratings don’t get copied, as iTunes doesn’t store it within the file. Some while ago I found a solution by storing the number of stars into the ‘Grouping’ Field, so I can recover the rating afterwards. Now, I came up with this little applescript do automate the write and recover process. Just run this script, copy you mp3 to the other library, run the script again, and voilá, you ratings are back - nice!
[shell]
(* 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
[/shell]
Btw. for each Star rating I do have a smart playlist which allows me to find those quickly.
Ruby: a nice way to get name of current method you're in:
This is a nice extension to get the name of the method you’re currently in (Ruby < 1.9)
[ruby]
module Kernel
private
def this_method
caller[0] =~ /`([^’]*)’/ and $1
end
end
[/ruby]
for Ruby >= 1.9 you can uses this:
[ruby]
module Kernel
private
def this_method
method
end
end
[/ruby]
