Unless you have been living under a rock the last few days you will be aware of Google’s new social networking product – Google Buzz.

Unfortunately it would seem that some assumptions made by the designers and the automatic opt-in nature of the service has lead to some serious issues.

For me it underlines some of the problems with entrusting your personal data to the cloud. That is not to say of course that it is a user’s fault that their data gets shared in such a way – everything in the day to day usage of these tools gives the user a reasonable expectation of privacy.

The trouble is, that this expectation is largely an illusion. When using cloud services, you are entrusting them and you hope that they will exercise the same care when dealing with your data as you would – but unfortunately this is rarely the case.

Whether through carelessness or malicious action information has a tendency to leak. Assumptions made by the design team can be proved poor. So in short, never put anything on the internet that you wouldn’t be happy to see on a billboard.

I have just written a very small Akismet plugin for Elgg.

When enabled and configured, this plugin will scan newly submitted comments of the ‘generic_comment’ annotation class.

While spam comments are rarer on Elgg due to the fact that most sites don’t allow anonymous comments, this could be useful for people who are getting spam comments from people who have signed up.

This plugin comes into its own when you allow anonymous comments, such as on a site I recently built for a client.

Extending this plugin to scan other content should be fairly straight forward for even a novice coder, but if I have time I’ll provide an interface to do so.

Anyway, go get it here, or check out the project page on google code!

This Christmas I finally bit the bullet and treated myself to a shiny XBox 360. Ostensibly this was so that I could experiment with console development, but mostly I have used it to play Gears of War.

In a slight departure from what I usually talk about, I thought I’d quickly jot down how I got the wireless controller to work with my Ubuntu XBMC media PC.

The wireless controller provides a slightly more usable remote than my iPhone (which must first be unlocked making quick pauses impossible) or rather flaky wireless keyboard, so hopefully this will be useful to someone.

Getting started

My media PC currently runs Ubuntu Karmic with XBMC. To begin with you will need to install the XBox kernel driver (already installed on Karmic).

Most importantly however, you will need to get yourself a XBox wireless gaming receiver for Windows – which I got included with my second controller. Xbox controllers do not use standard bluetooth, so you can’t just pair in the normal way using your existing hardware.

This howto has some more info…

Configuring XBMC

Assuming you have your module installed and controller paired you will need to tell XBMC about it by configuring a keyfile:

  1. I used this keyfile as a starting point. Download and save it as ~/.xbmc/userdata/keymaps/Keymap.xml (note case).
  2. Find out what your computer thinks the controller is by looking at the output from: cat /proc/bus/input/devices – you want a "Name" that says something like "Xbox 360 Wireless Receiver"
  3. Replace all occurrences of "Microsoft Xbox Controller S" with this value.

At this point if you start XBMC it should respond to the controller. If you are lucky this is all you will have to do, however for me I had to mess around with the key bindings a bit since the example keymap file didn’t match my controller exactly.

If this happens to you there’s not much I can suggest other than to bind one key at a time, restart XBMC and see what button that maps to then repeat until all your keys are mapped. I’m sure there must be an easier way that I’ve overlooked, feel free to comment below!

For what it’s worth, here is my modified (but somewhat incomplete) key file which has largely sensible bindings. Hack away to get it working how you like.
