For my new website I have been working on for a while I want to generate an image of the waveform of all audio files uploaded on the server. A trip down google avenue quickly led me to this post on andrewfreiday.com. He describes his search for the very same and comes up with a solution using lame to convert the mp3 file to a wave file and a php script to generate the image. I’m going to use his approach and couldn’t resist rewriting the script.

You can download my script for generating a waveform. It is licensed under the Apache License v2.0 because the original script was (I usually don’t bother with a license).

Update: I now use a different plugin because I want people to be able to write something on their wall when liking a post.

I just installed a plugin that adds open graph data and a like box to each page on this site. I like to have it configured this way; specifying meta data in the header my pages, it all feels semantic web-ish.

Of course I needed to make some changes in the code to make it all work.

Source code My WordPress powered website has been running for quite some time now, and today I finally replaced the default theme with something I like better, Suffusion, and customized it to my needs.

I had installed some syntax highlighting plugins before but disabled them because I couldn’t get it to work properly. Now with the pretty new layout all posts with snippets of unhighlighted source code were a real eye-sore, so that needed to be fixed as wel.

I’d like to use PDO in conjunction with MySQL, but in the PHP installation shipped with OS X by default only pdo_sqlite is enabled. I do not want to compile my own Apache or PHP so the way to go is to simply add the pdo_mysql module. I followed these instructions but after running phpize there were some warings on my screen and no makefile to be found. My current PHP version is 5.2.8 and I used the source of 5.3.0, so I tried again with 5.2.10 (since no other version was available at the PHP download page). Both yield the same result, namely that it compiles, installs and won’t start.

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so' - (null) in Unknown on line 0

Following instructions in the comment to remove all architectures but the x86_64 have no effect. I think I have to compile my own PHP installation and have apache use that. Which sucks so much I decided to just wait for Snow Leopard and pray that either pdo_mysql is installed or dynamicly loading libraries is allowed there. I am happy to inform you all that the first is the case. Hurray!

This is my first post on the third reincarnation of my weblog. It all started years ago when all of a sudden many people around me started with their Livejournals. I was socially forced to start one of my own, not in the least to keep up with their lives and be able to follow the conversations in my own house. As I felt the need to keep control of my blog in my own hands grow I purged my livejournal and created a blog on my own website.

Now as a proud web developer I like to think I can create anything, and thus can write custom software which fits exactly to my personal needs. But as a lazy-ass blogger I don’t want to spend all that time reinventing the wheel, I want everything, and I want it now! Installing WordPress comes close enough :).

Now I have a way simpler way to write blogposts, and I hope I am going to because it’s fun, and even more fun reading back those posts later (I know this because I am importing old posts into this blog and really enjoy reading and formatting them). I also installed a livejournal crossposter, because the LJ people don’t do RSS or reading other blogs a lot. Lets see what happens.
