the first few and last few pages always selectable with some context

This week I received a logitech squeezebox radio, which is basically an expensive toy that allows you to listen to either "internet radio", or music streamed from your own PC via a portable device that accesses the network wirelessly.
The main goal of this purchase was to allow us to listen to media stored on a local computer in the bedroom, or living-room.
The hardware scans your network looking for a media server, so the first step is to install that:

Today was Playgroup. We had a pretty early start to the day, and Zoe wanted
porridge for breakfast, so we made that together in the Thermomix, and she got
dressed while it cooked.
After a bit of TV, we biked over. I got to witness semi-firsthand my first
mother-to-mother altercation. I said hi to a mother I'd met a previous week,
and asked her how she was, and got "Pissed off" as the response. Apparently a
reasonably large boy (I'd put him at about the 4 mark) had been in the face of
her daughter, and distressed her daughter a bit, so she'd apparently politely
told the boy to back off, and then been revved by the mother of the boy for
talking to her son. The boy continued hanging around her daughter, and she left
Playgroup not long after telling me all about it.
I worked out later on that the mother of the boy was one of the women who
helped run the Playgroup. Fun times. He was a bit out of control. He full on
screamed at me at the end of Playgroup for no reason. His mother did make him
apologise to me for that, without me requesting it.
There were some dress ups (mostly skirts) today, so Zoe had a fabulous time
cavorting around on the stage in a big pink lacy skirt, doing "ballet". She
dragged me up on stage with her, and we danced around for a bit. It was quite
fun.
She was very helpful at pack up time, and was bringing a lot of equipment back
to the storage room at the back of the hall. I was helping load stuff into the
large crate in the storage room. After parachute time, I lost sight of her
briefly, and after a quick search, deduced that she must have gotten herself
locked in the storage room. Sure enough, that's where she was. She was only
missing for as long as it took me to notice and search in all the other
possible places, so she wasn't particularly distressed. Poor thing.
After Playgroup, we biked back home, and I had another photo I wanted to print
out, so we drove over to Officeworks and had a sausage sizzle after we got the
photo printed out, and then drove back home.
Zoe had a pretty good bedtime last night, so I decided to try skipping her nap
today.

I have just pushed our pseudo-monthly batch of keyring updates to Debian. I am happy to inform you that, while the situation described in 
The deadline for sponsored registration for DebConf11 in Banja Luka, originally May 8th, has officially been extended to May 19th. The reasons for the extension are as follows:
Thanks to a significant increase in sponsorship from one of our main sponsors, we have been permitted and encouraged to welcome more people to the conference. The extension is a one-off occurrence in response to this new development, and to allow any potential attendees time to access more information before registering.
Registration is required for everybody who plans to attend any part of Debconf. Access to the conference venue, food and accommodation is controlled through the registration badge. The only exception to the registration requirement is for those who plan to only attend Debian Day.
It is possible to request sponsorship for food, accommodation, and travel. Those who have been involved or contributed to Debian or to other open source projects are eligible to apply for sponsorship, which will be decided on a case-by-case basis.
The professional and corporate categories are for those who are sent and sponsored by their companies. Professional registration covers the actual costs of conference attendance, while corporate registration is just over double that price, and is aimed at those who, besides paying the actual costs, also want to contribute money and help Debian.
