There are so many sites on the internet now that offer sacred music suitable for the Mass that I have started losing track of them. This is my attempt to bring them all together on one page. I’ll try to keep this up to date as I find new sites.
Polyphony
Organ/Hymnody
Propers
Ordinaries
Psalmody

Today I purchased a Cisco 2950 switch and needed a console cable (RJ45 to DB9) so that I could set the switch up. Rather than pay through the nose for a pre-made cable, I realised that I could make my own one from an old serial cable. You just need a spare RJ45 plug and a crimper.

Django 1.0 has been released. I haven’t had a chance to play around with it yet, but it is a vast improvement on 0.97. You can read the release notes here.
GeoDjango is a geographic framework for Django that is now included as part of the Django distribution. It looks fairly good and I’ll be using it on some upcoming projects. There are some presentations here if you want to get an idea of how it works.
Google Maps has its own SRID: 900913. 1337-speak for Google. If you want to use it with PostGIS, you’ll have to add the definition to the spatial_ref_sys table.

Ben has a great tutorial on setting up a Dynalink RTA1320 or RTA1335 in half bridge mode so that you can have a world routable IP on a separate router (ie, a Linksys WRT54G). I have pretty much the same setup as Ben – the only difference is that I have a Dynalink RTA1335.
I can highly recommend these Dynalink products. So far I haven’t had any problems and I’m surprised at the quality of the firmware – far better than products from much bigger companies (ie Linksys, D-Link, etc). I can also highly recommend the Tomato firmware for the Linksys WRT54G wireless router. I used to run DD-WRT and was reluctant to move to Tomato because DD-WRT was quite good. After having moved though, I’m wishing that I had done it earlier. Tomato does everything that I need and it does it well.
One particular feature that I can’t live without is the bandwidth graphs in Tomato. There is also a feature to save the data usage logs to an SMB share so that if you have to restart your router, historical usage data can still be shown. Another feature that I’m quite happy about is the ability to force clients to use only WPA2 + AES to connect to the router. I ultimately want my network to be as secure as possible and forcing clients to use WPA2 + AES is a good way of doing that.

Dan Kaminsky recently discovered a vulnerability in the DNS protocol that could lead to DNS cache poisoning attacks. When a DNS lookup is made, the DNS server returns a random query id between 1 and 65,000. What Dan found is that the query id’s that were being generated by a lot of the DNS servers were not all that random, allowing someone to potentially poison a DNS cache by anticipating the query id. You can read more about this issue here. The Ubuntu security report is here. I would strongly recommend that you upgrade your DNS servers ASAP if you haven’t already.

I’ve been keen for a while to make some custom controls for Flight Simulator X so that I can control things like lights, flaps, gear, engine, etc. After a few hours searching around for various solutions, I’ve found the Precision Joystick Controller BU0836. It’s a USB joystick controller than allows you to connect up to 10 potentiometers and 32 buttons/switches. It’s pretty much exactly what I’m looking for and looks fairly easy to work with. It comes in at about $60NZD which is cheap enough that I’ll seriously look at buying one soon (after I get a yoke and some pedals) and perhaps blog about my experiences using it.
