Re: Remember Y2K?
If you wan to save memory space, you use a byte for the year. That would even outlast the *nix roll over.

In the early hours of 5 August 1914, only a few hours after war was declared, Britain carried out something that seemed to be minor, but was actually vital. A British cable ship severed five German overseas underwater cables, which passed from Emden through the English Channel to Vigo, Tenerife, the Azores and the USA
This cut direct German communications to outside Europe, most significantly to the United States. The British could now intercept German signals to their embassies. They were sent in code, but British codebreakers were eventually able to read them.
AFAIR, in Switzerland, payment processors charge a higher fee for magstripe transactions than for chip & PIN because of the risk, so the merchant has an interest to use chip & PIN.
In the Netherlands, most magstripe reader slots in are blocked to prevent mistakes.
That Groningen is sinking, is because the gas bearing rock is rather porous (no fracking needed).
Oilfields in the US are generally less deep than in Germany, so closer to the groudwater (Don't know about their gas fields).
(Very) Deep groudwater is often salty (fossil sea water) and undrinkable anyway.
The article talks about first generation meters obtained on eBay. For the meters to be deployed in the UK, DECC has written some resonably detailed security requirements: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/68898/smart_meters_equipment_technical_spec_version_2.pdf
Some high level requirements:
Compromise of one end device (like a meter) shall not lead to the compromise of other end devices (so no system wide passwords anymore)
Critical commands like switching off the power are digitally signed and subjected to a plausibality check. If a hacked utility tries to switch off all its customers, this will be stopped by the independent Data Communication Company.
PS. I work for a meter manufacturer in case you didn't guess that.
