I’ve finally got IPv6 working on my home network. It took a fair bit of fiddling! I’m using a tunnel and subnet provided by SixXS, which is run from a Linksys WRT54GS router running OpenWRT. I’ve had the tunnel running for a while, but it was only today that I got the subnet and was able to setup radvd to broadcast it. It does seem that radvd doesn’t like broadcasting /48 subnets though so I had to change it to a /64 to get it working.

By the way, never ever ever try uninstalling libgcc from an OpenWRT based router. In a moment of space clearing madness I did (trying to make room for IPv6 tools), and luckily was able to fix it by relinking the /lib/libc.so.0 file back to the right place.

# ln -s /lib/libc.so.0 /lib/libgcc_s.so.1

I really thought I’d bricked my router…

Very interesting article in the New Yorker about how we perceive. Via kottke.org.

The account of perception that’s starting to emerge is what we might call the “brain’s best guess” theory of perception: perception is the brain’s best guess about what is happening in the outside world. The mind integrates scattered, weak, rudimentary signals from a variety of sensory channels, information from past experiences, and hard-wired processes, and produces a sensory experience full of brain-provided color, sound, texture, and meaning. We see a friendly yellow Labrador bounding behind a picket fence not because that is the transmission we receive but because this is the perception our weaver-brain assembles as its best hypothesis of what is out there from the slivers of information we get. Perception is inference.

There’s quite a few posts of this type around the web, I just thought I’d document what seems to work best for me. The main thing this fixes is font rendering in Firefox, now it looks just as nice as it does in Epiphany!

Put the following in ~/.fonts.conf:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <match target="font" >
        <edit mode="assign" name="rgba" >
            <const>none</const>
        </edit>
    </match>
    <match target="font" >
        <edit mode="assign" name="hinting" >
            <bool>true</bool>
        </edit>
    </match>
    <match target="font" >
        <edit mode="assign" name="hintstyle" >
            <const>hintmedium</const>
        </edit>
    </match>
    <match target="font" >
        <edit mode="assign" name="antialias" >
            <bool>true</bool>
        </edit>
    </match>
    <match target="font">

        </edit>
    </match>
</fontconfig>
