Flex Open Source? Right...

There is a bug in the Flash player that makes it impossible to implement a RESTful architecture with a Flex or Flash backend. In essence, it is a buggy implementation of an http client - the client cannot get to the response body unless the reponse code is 200.. This is really bad. But what is an embarrassment for Adobe is that:
  1. That bug was opened more than a year ago
  2. It is marked as priority C only
  3. It was closed and had to be reopened after the community complained
  4. Adobe engineers suggested as a workaround to purchase LCDS Server
So, lessons learned (actually: lessons that proof in practice what was clear beforehand):
  1. It does not matter too much if Flex is open-sourced as long as the Flash player is not
  2. It does not matter at all if Flex or Flash are open-sourced if the community cannot apply patches and get them into the deployed player
Flex being open source is completely irrelevant.

Hey Michael

I just stumbled upon this one last night. Flex is suddenly not so sexy anymore. I dunno wether the RestService under will do , considering the rather huge drawback that it only seems to be usable in Adobe AIR. Haven't tried it yet...

Oh well...

Well, there are workarounds, but that does not help with Adobe's "Flex is open source"-claim. We can work around this, but we cannot fix it.
Thanks for the pointer - quite a nice write-up of the situation.

Python script to set genre in iTunes with tags

Now that I have started to seriously use iTunes I figured it might be nice to have the genre tag set in a meaningful way. Since I have a reasonably large collection of mp3s doing that manually was out of question - I wrote me a Python script to do that. There seems to be a large demand for such a functionality (at least I found a lot of questions on how to automatically set the genre tag) so maybe someone else finds the script useful. It is pasted below.

General Strategy

The basic idea is to use's tags for genre tagging. In iTunes the genre tag is IMO best used when it only contains one single genre, i.e. something like "Electronica", not something like "Electronica / Dance". On the other hand dropping all but one tag would lose a lot of information, so I decided to use the groupings tag for additional information that is contained in the list of tags that an artist has on In the example above that would be something like "Electronica, Dance…

mp3tagger on GitHub

On the mp3 tagger post I have received quite a bit of feedback and feature requests. Therefore, I thought it might be a good idea to do "social coding" and put the code on GitHub where it can easily be forked (and the forks can be watched).

Other than that, the latest version of the tagger contains these improvements:
the keys and secret are not stored in the code anymore, but entered on the first run and stored in ~/.mp3tagger.cfgyou can run the script in two additional modes: simulation and ask. In simulation mode no changes to mp3s will be saved, in ask mode you will be asked to save each change. Start the script with flags "-m simulation" or "-m ask", respectively.It is now possible to specify a list of genre tags that will be considered (additionally to the mp3 default genre tags). The list needs to be stored in a config file at ~/.mp3tagger_genres.cfg (in the "generic" section of the file). The full format this file needs to have is …
