One of my lecturers set her own book as the text for her course, but handed out photocopies of the relevant chapters. Of course, I'm not sure whether her deal with the publisher allowed her to do that, and I didn't want to enquire too deeply...

He's long since retired: it was a comment on the challenges facing the generation after the generation after his.

Except that he was a British researcher at a British university run on British academic lines, not US ones.

Tesco bags don't even need to be left in the sun. Use one to hold a few things together, put it in your loft for storage, and when you try to take it down it will have broken down into 5 to 8 millimetre fragments which seem to carry an electric charge, judging by the way they stick to things.

I don't have mod points, but I found this interesting. Here in Spain they charge for bags in the chain supermarkets, but in the "Chinese shops" (budget independent supermarkets mainly run by Chinese immigrants) and take-away shops they give you bags for free. A cheap bag in the chain supermarkets is only 2c, and the impression I get is that most people just pay it, although they do also sell reusable bags for 1€.

I should have quoted the part I was replying to:

DES was only broken by exhaustive search.

DES is broken without brute force (although it's also brute-forceable). It's more resistant to differential cryptanalysis than if the S-boxes had been random, but differential cryptanalysis is still better than brute force against it, and so is linear cryptanalysis.

I bet that the requirements document for that data storage centre was considerably shorter than the requirements for healthcare.gov, and there was probably more input from the people tasked with building it into how long it would take and what was a reasonable deadline.

You could say the same for video.

I think you've missed GP's point. Do you have evidence that those three were specifically ideas which came from Larry and Sergey?

The cunning approach would be to make it check for only the easiest to forge markers. E.g. if you make it ignore ultraviolet and just look for the yellow Eurion rings it will accept valid notes and any note which is a reasonable copy.

One of the three supermarkets I regularly shop in in Spain uses them. The device is separate from the cash register, and they definitely test notes as low as 20€. I'm not sure whether they also test 10s.

Sounds to me like a honeypot set up by US immigration, but maybe I'm just too cynical.

The direct quote in the summary talks about doubts over

whether the NHS can continue to provide free health care for all patients

The title says

British NHS may soon no longer offer free care

The person who transformed the first into the second has serious problems with either English or logic. "We may have to charge some patients" isn't the same as "We may have to charge all patients".

Your reference to "discontinuing free care" is ambiguous, but without qualifiers is easier to interpret along the lines of the title rather than of reality.

No, the phrase is "I refer you to the reply given in Arkell vs Pressdram".
