This might be well-known, but I though I'd mention it anyway, as it seems a bit mysterious at first sight.
If you live behind a HTTP proxy you probably are used to the two ways of making your system use the proxy: by http_proxy and no_proxy environment variables and by the GNOME Network Proxy Preferences (gnome-network-properties). But either way it can happen that simple sudo aptitude or sudo apt-get install foo fail because it tries to access the internet directly, ignoring the proxy setting. So, why is that?

Eclipse CDT: removing non-existent include paths
It seems that Eclipse CDT doesn't like it when you have a non-existent path in the list of project include paths. Fair enough. You can selectively remove the non-existent paths from your project via some mouse-clicking.
But if you are generating your Eclipse project via, say, CMake and you're unfortunate enough that you can't reasonably change the CMake project files (think of evil upstream and you not wanting to patch their overly complex build system changing with every release), what do you do? After a bunch of project regenerations removing of the include paths by hand becomes annoying.
As I was experiencing this issue, I decided to hack together an Eclipse plugin to resolve this for me. And here is the result: fixincludes Eclipse CDT plugin.

Linux 3.0 on ALIX 2d3
Update: Due to the way the current ALIX LEDs driver is implemented it cannot be used at the same time the generic GPIO driver is loaded. :-/ Luckily there's some work going on to resolve the issue - see this commit in linux-next.
Just an update: Here's a linux 3.0-rc4 config file for ALIX 2, more specifically for the ALIX 2d3.
This should have all the basic things on the board running, including Ethernet, USB,LEDs, GPIO (not tested), watchdog.
You most certainly want to hand-tune it for your particular setup. No WiFi driver is enabled in the referenced config -- if you have one (or two :-)) wireless NICs in your ALIX, you certainly want to add that to your configuration.
