UK watchdog snaps on glove to probe Tesco's 'security fails'

FAIL

No database breach has occurred at Tesco.com...

Surely this should be qualified with "yet" or "that has been made public".

If they can't even store passwords securely, how do we know that their intrusion detection is up to scratch, for all they know there is a copy of their database (or the interesting bits at least) sitting on a hard drive in some snot nosed script kiddie's bedroom.

ASA upholds customer complaint against eBuyer

So if Ebuyer have misbehaved here, does this mean that every advert should include specimen negative reviews?

How likely is it that we will see a film trailer along the lines of this?

In cinemas this Friday: Final Destination eleventy twelve *

Four and a half out of five - reviewer from the broadsheet

Bang, crash, wowee! - reviewer from the redtop

A complete borefest, you already know they all die - token internet film reviewer

It won't happen. The purpose of advertising is to persuade people to think your way, whether that means buying your product, supporting your cause, or some other more sinister motive, so the advertiser is hardly going to want to destroy the illusion created by their positive message by suggesting that their product is less than perfect.

*Disclaimer: I have never seen any of the films in the series, I'm using them to illustrate a point. For all I know they are great films.

Why the fixation on CO2

Just a thought, but has anybody ever considered the fact that perhaps CO2 has little (or nothing) to do with any recorded increase in temperature, and that perhaps it's all the extra HEAT we are releasing into the biosphere?

The Earth must have a certain capacity for heat dissipation into space, which under pre-industrialisation conditions was ***roughly*** the same as the energy received from the sun (less any stored in peat bogs etc.), hence the alleged stable temperature.

Energy from the sun ≈ Energy dissipated into space + Energy stored as future fossil fuel

In our current industrialised world, we are adding more heat energy to the system by burning fossil fuels, which represent a surplus of energy received by the Earth from the sun over millions of years.

Energy from the sun + Energy from burning fossil fuels > Energy dissipated into space + Energy stored as future fossil fuel (less storage than before)

And regardless of the efficiency of our fossil fuel power plants, even if they could achieve 100% efficiency, virtually all of that energy will end up as heat in the end, usually through inefficiencies elsewhere, although in some cases (electric heating, vehicle brakes) we intentionally dump it into the environment as heat.

Although this makes sense to me with fossil fuels, could somebody more knowledgeable confirm what effect the adoption of nuclear (fission or fusion) might have on the energy balance I have suggested?
