BCD3000 Djay Midi Mappings

tobi — Fri, 02 Apr 2010 11:13:26 +0000

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!

Rails flag_shih_tzu Plugin with named_scope

tobi — Thu, 20 Aug 2009 17:02:36 +0000

When it comes to store a load of boolean data into your model you easily end up with lots of columns which blow up your table unnecessarily. The developers at Xing solved this problem with a nifty Rails Plugin called flag_shih_tzu. The trick is to store all boolean values combined as a bit vector, which allows you to put up to 32 values (4Byte) within a single Integer column. Automatic generated access methods allows you to deal with you model as your are used to. Wanna see an example? (Taken from plugin docs)

class Spaceship < ActiveRecord::Base
  include FlagShihTzu

  has_flags 1 => :warpdrive,
            2 => :shields

end

enterprise = Spaceship.new
enterprise.warpdrive = true
enterprise.shields = false
enterprise.save

enterprise.warpdrive? #=> true
enterprise.shields? # => false

Nice, isn’t it?

Unfortunately named scopes where missing for selecting models easily. So another github fork, another fix, and here were are. Now this works as well:

Spaceship.flagged(:warpdrive).not_flagged(:shields).all

Update: replaced ‘routes’ with ‘scopes’ – I’m getting confused with that all the time, how come!?

Extending Active Scaffold as_paperclip_bridge to delete & update image/attachment

tobi — Thu, 13 Aug 2009 15:53:35 +0000

As you know I’m quite fond of working with Active Scaffold (AS) for data administration proposes. Quite recently we moved over to the RoR paperclip attachment plugin for file upload handling. I was even more happy to see a Active Scaffold bridge which integrates paperclip smoothly into AS as well. It’s created by and hosted here on github.

Unfortunately it didn’t provide the possibility to delete or update an image once it’s assigned to an object. Well no problem, another fork of mine, some coding and now it possible. I basically reused to code of the as_file_column_bridge. Check it out here:

Update: changes got merged into trunk, check it out:

My first GitHub fork: bounce-email

tobi — Fri, 05 Jun 2009 12:40:12 +0000

Hurray! I finally forked a github project. Yesterday I ran into the bounce-email gem by Agris Ameriks on Rubyforge. It’s basically a 1:1 port of the PHP Bounce Handler classby Chris Fortune and not very rubyified. Thanks to David Reese, bounce-email is forked on github and I could easily extend it.

I rubyfied the class, did some code cleanup, added (yet a very simple) way to get the original message, and gained some performance by paring message only on demand. A testcase was broken as well the Rakefile, both are fixed. See the update here:
