Some form of logging is also needed

It's not enough just so make transmission of data secure. Many of those whose medical history is being used will want to know who is accessing it and for what purposes. This presents a more difficult problem.

New Windows 10 privacy controls: Just a little snooping – or the max

Re: Rule number 0

The initial version of Raspbian for USB stick seems to work quite well; and will presumably be well supported; albeit that it's a bit slow with USB 2.0. This could be a useful dual-boot option for users who aren't technically minded and would only need to know how to disable the Windows internet connection.

Indeed it might be this or something similar that is a turning point for widespread uptake of Linux.

Re: Now that is what I call a bait-and-switch

You have to go and declare yourself.

You have to go and declare someone. To get started, Tesco's mobile costs £1 for a SIM plus £10 to load it if you need a burn phone. Local shops and pubs will have a postcode that is plausible when compared with ISP data and local searches for weather etc. that might otherwise betray the real user.

Relevant and accessible?

The University of Leicester web page giving details of this study includes a link:

"Read an article on why it is important to make physics and science education relevant and accessible to the public."

Rather than making physics 'relevant and accessible', these zombie papers seem to me to endorse the complaint that is often made by university teachers that a great many students arrive with an abysmally poor understanding of mathematics and science, and thus need remedial education before they can properly follow a degree course.

The papers may have been little more than fillers for the local student journal. It was perhaps a mistake to promote them as the university press office did.

Why .. Miele... 10 year parts and labour warranty?

I checked with my friend. The washing machine actually failed 3 years + 2 months after she bought it and she hadn't bought the extended warranty to cover beyond 3 years because this costs almost as much as a new machine. Her comment on the downvotes was, "and it doesn't spin my woolies properly."

Re: Best of a bad bunch...

There are people who ... buy Miele appliances.

It took considerable effort to find the correct replacement heater for a friend's Miele washing machine, which failed after 14 months' light use. It also took a small age to find information about how to change it. I'm by no means sure that the construction is actually better than other makes; certainly not worth twice the price of competitors' machines, some of which provide better controls.

How times have changed

Here is an excerpt from a 'Report from the Select Committee on the Police of the Metropolis', 1822. It puts the argument against snooping rather well.

“It is difficult to reconcile an effective system of police with that perfect freedom of action and exemption from interference which are the great privileges and blessings of society in this country; and Your Committee think that the forfeiture or curtailment of such advantages would be too great a sacrifice for improvements in police, or facilities in detection of crime, however desirable in themselves if abstractedly considered.”

"I wonder what people who voted leave think of the snooper's charter anyway?"

At least some of them have been doing what they can to oppose it. Though I wish I could have done more, I myself been opposing excessive use of DNA profiling and other forms of snoopery for a couple of decades.

Of late there has been a great deal of discussion about DDOS attacks and so forth and the possibility that a foreign power might bring the internet down, thus causing huge economic damage.

Fleming's left hand rule?

Since reading the article I've been puzzling about the direction in which the force appears. Fleming's rule says it will be at right angles to the direction of current flow and at right angles to the movement of the wire carrying the current through the magnetic field. Won't the force on the wire be sideways, causing the wire to bow and pulling the weight at the end back towards the satellite?

The Open University does a free course, Introduction to cyber security: stay safe online. At first glance this looks as though it might be a cost-effective way of getting members of the public to be more aware and more able to defend themselves against at least some of the threats. There probably won't be too many takers, but at least someone is trying.

Re: scrap inflation?

"Meanwhile the universe appears to be expanding at an ever increasing rate "

Maybe the accelerating expansion was all a mistake, down to there being insufficient observational data at the time. Professor Subir Sarkar of Oxford University's Department of Physics has used the larger dataset that is now available. He suggests that "the apparent manifestation of dark energy is a consequence of analysing the data in an oversimplified theoretical model."

Deliver-oops! Takeaway pusher's customers burger-ed by hijackers

Take the cash - use the card

A couple of years ago a chum who was visiting had paid for our meal at a local pub/restaurant with his credit card. A few days later the details were used to pay for a rather large takeaway order order from at a nearby pizza parlour. I puzzled for a while as to why anyone might do this and then realised that it's a means of getting cash.

The way I imagine this scam is done is that a couple of people work together in the catering trade, where there is a fairly fast turnover of casual staff. One collects card details, which aren't used for a few days. The other, at a different establishment, waits until a customer pays cash for a large order, trousers the money and pays using the stolen credit card details.

Unless one or other is caught/observed in the act of collecting or using the credit card details it would be rather difficult to bring a prosecution, even if it was possible to find out who the perpetrators were.

using liquid helium or liquid nitrogen, which is expensive.

Liquid nitrogen is not terribly expensive. It used to cost about the same as beer. And there's a lot of nitrogen about, just needing a rather good refrigerator to cool it, as it comprises 80% of the atmosphere. The supply of helium is in contrast rather limited and it needs a special multi-stage refrigerator to liquify it.

Re: Increase in the Standing charge likely.

IANAL but I'd imagine that reprisals for changing the WiFi password would be breach of contract on the part of the supplier, in that they have both failed to make it clear that such a change would incur a penalty; and also failed to provide instructions on what to do if a password change should becomes necessary. In addition, as I understand it, unreasonable terms and conditions are disregarded should a case come to court.

Magnetohydrodynamics

It's sad to see Hannes Alfvén lumped in with new age mystics. He does seem to have come in for a great deal of undeserved flak; for opposing Catholic dogma posing as science, for coming into science from a background of engineering, and for having the temerity to suggest viable alternatives to orthodox explanations. Although the Alfvén-Klein hypothesis didn't work out, he did at least have the courage to point out flaws in big bang creation.

Roger Penrose's latest book, Fashion, Faith, and Fantasy in the New Physics of the Universe provides interesting perspectives on contemporary cosmology; it is similarly critical. (It might make a nice Christmas present.) And David Tskilauri's paper showing that the jxB force can account for anomalous galactic rotation without the need for elusive dark matter is worth a read.

It will be interesting to know how this phenomenon changes as the Sun's magnetic field oscillates. Presumably the dynamical field reversal is associated with changes in the distribution of charge throughout the solar system and beyond.

'Pavement power' - The bad idea that never seems to die

David Pollard
Silver badge

Wading through treacle

Wikipedia, your friend and mine, tells us that "a healthy well-fed labourer over the course of an 8-hour work shift can sustain an average output of about 75 watts." If the walkway is generating "between 4W and 8W" per person then the input power will need to be something like 20 or 30W; probably about as much as is expended in a gentle stroll.

I imagine that people would soon learn to walk along the edges of the pavement where the going is likely to be somewhat easier. Even without such avoidance the projected cost per unit energy is presumably horrendous, and, crucially, the EROEI negative.

Quantum traffic jam of atoms could unlock origin of dark energy, physicists claim

... hasn’t been experimentally proven yet

The mystery of why the universe is expanding at an accelerated rate might well be solved in a rather different way. The idea of accelerating expansion was based on observations of supernovae that had been available in 1990. A recent paper by J. T. Nielsen, A. Guffanti & S. Sarkar using the larger dataset that is now available suggests that expansion may in fact be constant.

Re: Cause and effect?

... UK goods are now more attractive to overseas buyers [o]nly to the extent that they don't depend on imports.

When the pound devalues with respect to all other currencies, the cost of the imported component of goods which are re-exported remains constant in terms of external currencies. With a 'weaker' pound the sterling cost of the added value in such re-exports becomes less expensive in terms of external currencies. So trade dependent on imports does become more competitive, albeit by a smaller amount than goods or services which are wholly sourced within the UK.
