American politics! This flash movie is quite interesting. Got the link from a friend. This CEO test for Bush should also be read.

pgLOGd is a nice similar system for logging apache entries to postgres.

Now to find a decent php or python based log analyser, then hack it to use pgLOGd.

Update: This guy has a nice analysis of log analysers tools: Log Analyzer. Before I saw this though I pretty much figured that AWStats was the way to go.

Permanent Lenses in Sight

Here is an option for those of us who aren’t sure if LASIK is the way to go: Permanent Lenses in Sight.

I’m wondering if in a few years time, this might be a method to implant electronic eyes.

TCP window scaling and broken routers

Something to be aware of when you upgrade to, TCP window scaling and broken routers:

In the 2.6.7 kernel, the default scale factor is zero; in Linus’s BitKeeper tree and the 2.6.7-mm kernels, instead, it has been increased to seven. This change has brought the broken router behavior to light; suddenly people running current kernels are finding that they cannot talk to a number of systems out there. One of the higher-profile affected sites is Gentoo users are, unsurprisingly, not pleased.

In the mean time, anybody running a current kernel who is having trouble connecting to a needed site can work around the problem with a command like:

echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale

or by adding a line like:

net.ipv4.tcp_default_win_scale = 0

to /etc/sysctl.conf.

Following up from the Earth at Night post a few days back, here is a slashdot post with a link to a site with a population density map.

Earth at Night

Astronomy Picture of the Day is a constant source of interesting view-points on our universe.

I think it would be revealing if we overlayed a population density with todays picture. You would probably see which parts of the world have a high level of living compared to those that don’t.
