Children’s books
Ok, it’s clear that books for children must take liberties in terms of realism. For example, we have these nice book about a small polar bear. That he befriends a small sled-dog is par for the course for such book. All fine and dandy and it makes nice reading. But this page made me go WTF:
A polar bear who likes to swing through the jungle. Sheesh.
For me, this is like science fiction: It’s ok to make some wild assumptions, but then please be consistent. Don’t have him run races over ice on one page, and swinging like Tarzan on the next.

Kook Alert
Recently, two mails of a conspiracy theorist sneaked past my spam-filter. Pure flashback to the heyday of the good old Usenet kooks. Consider this quote:
The Jewish nazis also continued to send ‘messages’ and ‘feedback’ to me through the media and internet and through the EBL – Electronic Brain Link – whereby, among other things, they ‘invited’and sucked me in to directing my attention and using my amazing power on images in magazines, the internet, TV and other media
I mean, if that doesn’t trigger your kook-detector, nothing will.

More upgrading tidbits
As mentioned before, I disabled xen before the etch->lenny upgrade. Now I’ve re-enabled xen, and the following bits may be of wider interest:
My server at the Hetzner hosting center has one static IP address and a small network that is routed towards that IP address. So my plan was to use this small network (88.198.160.176/28) for the virtual switch inside the xen Dom0 and connect all the domUs to it. I solved this the following way:
In /etc/network/interfaces I tell Debian to create the bridge and use br0 as the interface of the dom0 into that bridge:
auto br0
iface br0 inet static
pre-up brctl addbr br0
address 88.198.160.177
netmask 255.255.255.248
bridge_fd 0
bridge_hello 0
bridge_stp off
That way, the xen scripts themselves have little to do. The settings in /etc/xen/xend-config.sxp are:
(vif-script 'vif-bridge bridge=br0') (network-script network-route)
In the config-file for each individual domU, I just use something like
vif = [ 'ip=88.198.160.178,mac=00:16:3e:77:e2:79,bridge=br0' ]
but I’m not sure whether that’s actually needed at this point.
Concerning the domUs: The hints in the Debian Wiki were helpful, especially about changes to the console handling.
Just in case somebody was wondering why this blog was down over the weekend:
I finally bit the bullet and upgraded my server from Debian etch to Debian lenny. And while doing that ran into Bug #541371.
Otherwise the upgrade was pretty painless. But as timid (some might say sane) as I am, I disabled xen before the upgrade. Getting that up and running with a new kernel will be the next step. This is especially tricky as I do not have a remote console, just the Hetzner rescue system.
Oh, and as I’m no longer running a pre-historic wordpress, this blog might get a new design sooner than later.
