No, you're right, it doesn't pose any danger. However, it does include
data that people might reasonably want to keep secret, for example that
they are so poor that their children get free dinners. As I said,
schools are required to keep that information confidential.

You and I know that. But the "Paedos Are Everywhere And It Would Be
Awful If We Let Them Know The Children's Names" excuse is so widely used
by the authorities against the public, that it is nice to be able to
turn the tables for once.
Criticising the government is not illegal, but often on investigation turns out
to be linked to serious offences.

Yes, if you mount a largish mirror ridgedly so that the CCTV camera
ends up "looking" at the Sun.

Most cameras will be absolutely fine. Pocket cameras have such small
lenses that the total collected light is small and the focussed spot is
large, so the energy density is low.
SLRs with large lenses are potentially at risk, because they may have
large aperture lenses, so lots of collected light and a small focal spot
and high potential energy density. However, in normal operation they
also have a physical shutter, so the sensor is only exposed for a short
period. The risk of damage occurs if you set them to have a long
exposure *and* point them at the mid-day sun, although why you should do
that, I have no idea.
There is more risk of you damaging your retina by looking through the
viewfinder of an SLR pointed at the sun...

I wouldn't trust a supermarket computer any further than I could throw
In front of me is a shelf label I purloined from Sainsburys a month
ago. It says:
fruit bowl yogurt flakes raisin 5 x 30g
�11.06 per kg
Every week we go and buy a pack
Every week we refuse to pay �1.99 for them, and offer �1.66
Every week we get them for �1.66.
Sainsburys were told of this a month ago (verbally, to customer
And again 3 weeks ago (to a "manager", whose action was to scribble
through the figures "�11.06 per kg"
And again 2 weeks ago, written in the Complaints Book (together with
the information that the shelf label would be passed to whatever
Trading Standards call themselves these days).
Trading Standards have been informed.
The local newspaper has been informed (there have been no slow news
It's STILL mathematical nonsense.
if long gets broke, try
http://www.sainsburys.co.uk/groceries/index.jsp and then enter "
fruit bowl yogurt flakes raisin " in the search box
The price of 150g multipack is somewhat higher than 5 individual packs
as well..... whaat's the idea there?
