Music

The last few weeks I spent most of my spare time learning a little Django and rewriting the old DAD (Digital Audio Database) code (which was written in PHP) to something a little more modern and malleable.

All these topics deserve separate posts, but for now I’m just content hooking up the various pieces of infrastructure for the overall project.

So, I was happy as a child when I was able to do a query for ‘all tracks that contain a hidden track’ (which I look up by doing level analysis on the files, and figuring out where there are sections with a reasonably large section of silence).

The full list for my collection is below, but it definately picked out the ones I expected, like ‘All Apologies’ (I can’t count the times I was annoyed when a music player played it then shut up for 10 minutes), Lift To Experience’s “Into the Storm”, the Auteurs track, and the beautiful beautiful hidden track at the end of Placebo’s first album.

Pretty soon this player will play these hidden tracks correctly, and DAD will allow you to rate tracks separately.

Here’s the current list (some audio files are repeated because they contain more separate slices):

Python XML parsing

I’ve always had this nagging feeling any time I write XML parsing code in Python that it just ought to be simpler.

Conceptually, I tend to always think that an XML document is really just a big nested python dictionary, and I should be able to walk it as such, or even better, as a composition of objects. That’s probably a gross oversimplification and probably not correct according to spec or some corner use cases, but really, that’s just how my brain works. Show me an XML document and I’ll show you a big dictionary tree.

So I’ve always been disappointed with the experience of having to write actual XML parsing code. In Flumotion I think we’ve gone through three different XML parsers as well, depending on which developer was supposed to rewrite or add some piece of code that had to deal with XML config files.

So each time I have to write some XML parsing code again, I tend to go look if there’s something better out there. This time I stumbled across a blog post that echoed my sentiments exactly. And it came with a solution: xml.etree.ElementTree. Finally ! A library that more or less maps to my mental model. Reading through the tutorial then writing the code I needed to parse my file took a lot less time than handrolling yet another set of functions to parse tags would have.

I’m posting this to increase the google juice of xml.etree.ElementTree. It simply doesn’t show up when you google for python xml, and it should be hit number 1!

mysql and utf-8

Someone will probably tell me what knob to turn or what option to twiddle to make this Do The Right Thing, because I can’t let myself think MySQL and its tools would still not support utf-8 correctly:

mysql> select * from artist where artistname like '%gur%';
+-----------+------------+-----------------+
| artist_id | artistname | first_letter_id |
+-----------+------------+-----------------+
|       258 | Sigur Rós |               3 | 
|       620 | Guru       |              15 |

wordpress I hate you

After seeing that I possibly might have had some exploits run on my site again, I upgraded to wordpress 2.8

After reading up on hardening wordpress, the official site mentions AskApache, some plugin that helps hardening. I’m not too sure about it yet, because it wants to be writing .htaccess files in my directories and for that I have to open up more than I would want. But hey, let’s give it a go.

At some point it creates a username and password that you choose. I go on and configure stuff, not knowing very well which of its many modules I’m supposed to activate, or why.

I forget about it, and ten minutes later I check my mail. I have a mail from AskApache. With my login details. And the password in plaintext.

Is the WordPress security model just fundamentally broken ?

5luendo birthday party

Filed under: Fluendo,Releases — Thomas @ 10:37 am

Yesterday was cause for celebration. We got together to celebrate five years of the Fluendo Group!

01072009

The picture quality is bad, and not everyone is in it, but I just took it on a whim after marveling how many people were there. I didn’t even know all of them – yes it’s gotten to that point. 67 months ago I arrived in Barcelona without the company even being created…

We celebrated with mountains of cheese and rivers of wine which in the first year would have lasted us a few weeks and now only lasted an hour.

As magical accidents sometimes happen, today is also the day Fluendo received the certification confirmation from Dolby for our DVD player. It didn’t take long to land in the webshop, so finally our DVD player is up for sale! So you know what to get us for our birthday – a shop checkout with the dvd player in your cart.

Good timing – that means that at this year’s GUADEC/Desktop Summit I know what the answer will be to one of the most asked questions I get.

This is the first GUADEC I’m going to with Kristien in tow, I hope she can manage. I’ll be there from Monday through Friday, because the week is bookended by two weddings. Looking forward to a GStreamer summit on Thursday discussing 1.0…
