Appointments on hold as (computer) virus wreaks havoc with NHS trust systems

David Pollard

Coincidence or delivered in person?

Earlier this year, in late January, Lincolnshire County Council's computer network was shut down after being hit by ransomware. Is this attack on LIncolnshire NHS in any way connected?

Humans don't understand how it works

MIT may have just the thing:

"At the Association for Computational Linguistics' Conference on Empirical Methods in Natural Language Processing, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) will present a new way to train neural networks so that they provide not only predictions and classifications but rationales for their decisions."

Though I was far from being one of her supporters, she deserves to be remembered for the good work she did in getting the Montreal Protocol internationally agreed and for persuading her chum Ronald Reagan of its relevance.

Perhaps we need more politicians who have some understanding of science.

NHS patients must be taught to share their data, says EU lobby group

David Pollard

How about sharing *their* data?

A great deal of research goes unpublished; the so-called 'negative data'. When drug trials don't show a benefit for the promoter they get quietly hidden. Then data for published work is often either not available, incomplete or in a form that is hard to use. And a large proportion of the research papers themselves are published behind very expensive paywalls.

The non-profit organisation PLoS has changed and is changing the publication landscape, and academic campaigns for open access to research papers and open data also play a part. But there is a long way to go.

Big Pharma can have details of my medical history when they publish all their research data, including that which shows their products in a poor light, and when they stop charging people to read the papers

Open note to Gracie Mae Bradley

Madam,

You are quoted thus: Against Borders for Children co-founder Gracie Mae Bradley added: "There is still time to resist this divisive and risky scheme".

The time for action was back at the turn of the last century, when realisations of Blair-Blunkett-Straw control-freakery were being dreamed up and then implemented. The 'Every Child Matters' scheme set out to provide multiple government agencies with access to all data held about children. One particularly ghastly part of the programme, RYOGENS, had been promoted with claims that it could predict criminality,

A good account was provided by Ross Anderson and colleagues at the Foundation for Information Policy Research, back in 2005/6.

http://www.fipr.org/childrens_databases.pdf

It won't do much good for schools not to record details of nationality. Firstly in most cases this information is likely to be easily gleaned elsewhere. Secondly, it's racial prejudice that is the problem, not a particular child's nationality. Hiding details of nationality may hide the prejudice, but if fails to deal with it.

What is required is to have the software that is used to run the child databases open to public inspection and likewise to have the uses - who accessed that data, when and why - reliably logged, appropriately inspected and open to magisterial enquiry. Neutral and trustworthy judges, high-level civil servants and similar public figures are probably rather thin on the ground, those with an understanding of technology even more so, but their scrutiny is what's needed. Clearly it's not appropriate to make confidential information publicly available, but, equally clearly, appropriate methods are needed to ensure that when government bodies hold such information it is handled in a manner which is democratically accountable.

The opportunity to oppose computerised collation of data, if ever there was one, passed by long ago. What we must try to do now is to ensure that the technology is used wisely.

David Pollard

When DNA profiling was introduced, the original statute allowed its use only for checking crime stains against potential suspects. So called 'DNA trawling' and familial matches were not allowed; and the data was to be discarded as soon as comparisons had been made. However, shortly after its introduction an apparently innocuous act was passed which modified the regulations to allow records to be kept "for statistical purposes". Beyond the promoters, few MPs would have noticed.

UK cops failed to act on Canadian intel on child abuse

David Pollard

UK police sat on intelligence ... for 15 months

Only 15 months?

In response to disclosures about child abuse by Jimmy Savile and various other ghastly goings on, Theresa May announced in July 2014 that there was to be a full enquiry into historic child sex abuse. This, she declared, was to address "serious failings by public bodies and important institutions." Now, 27 months later, and despite the expenditure of large amounts of public money, there still hasn't been any progress.

Re: They could have build 10 GW scale tidal plants for the same amount of money

An Archimedean screw generator went into operation on the Thames at Osney Lock in Oxford in 2014. The site is as good as it gets. The total cost was £700,000, maximum output is 49 kW and anticipated typical annual energy generation is 179,000 kWh or more.

http://www.osneylockhydro.co.uk/

This scheme has an expected lifetime of half a century or longer. It will produce an average of about 20 kW so the capital cost is £35,000 per kW. If interest, maintenance and depreciation could be covered by 5% on capital this would amount to about 20p per kWh. Presumably the Environment Agency would also be looking for commensurate sums for their Abstraction Licence if such schemes became widespread.

In the TED talk linked above by A/C, David MacKay suggests our total energy use in the UK is 125 kWh per person per day. So Osney Hydro's output is equivalent to about four people's total energy consumption, the provision of which would cost them £175,000 each.

The scheme is terribly green and the promoters I'm sure are terribly well-meaning, but for my money I think our dependence on fossil fuel could be replaced sooner, less expensively and rather more effectively by investing in small modular reactors, and thorium and Gen IV research.

Re: They could have build 10 GW scale tidal plants for the same amount of money

The Thames alone had more than 20 water mills upstream of Teddington. I does not take a genious to imagine bringing the head of water (ie weirs) that exist to this day and generating power from it.

The average flow in the Thames at Oxford is about 20 cubic metres per second, 60 cubic metres per second at Windsor. The fall over the 95 miles or so that the river meanders to reach Teddington from Oxford is about 185 feet. Only a portion of the energy can be extracted without causing silting, and conversion efficiency will not be high. In total one might somewhat hopefully expect to extract an average gross power of the order of 50 tons/second falling through 10 metres.

Now I may have done the sums wrong, but this looks to me like 5 MW; maybe 3.5 MW delivered.

The problem with hydroelectricity, as David MacKay's work shows, is that while it may be useful in particularly suitable situations the energy density is not terribly good. I will leave it as an exercise for the reader to work out what the capital cost of generating energy from the Thames in the way might be, and what environmental costs such a scheme would likely entail.

The pint is for Gridwatch for providing a fine example of how the net should work and how important public data can be made easily accessible.

It might be of benefit to one or two commentards if they were to buy or download.a copy of the late David MacKay's Without the hot air, which is equally lucid, and use this along with the grid data to get some understanding of the scale of the problems that must be solved in order to reduce production of carbon dioxide..

Zuckerberg to spend $3bn+ to rid world of all disease by 2100 (Starting with Facebook, right?)

David Pollard

Sofosbuvir?

Over 200 million people worldwide are infected with HepC. The drug Sofosbuvir presently seems to offer the best chance of a cure. The production cost is about $1 a pill, one a day being taken for a 12-week course along with other relatively inexpensive medicines. In the UK the price that the NHS would pay for such a course of treatment is currently about £35,000.

A firm called Gilead Sciences had bought the patent for the drug, paying $11 billion to a startup company, Pharmasset when their results showed promise. Their development of the drug had in turn been based on a research breakthrough at Cardiff university which had not been patented.

Sofosbuvir came to the market in 2013. By the first quarter of 2016 Gilead had collected £35 billion in revenue from HepC medicines.

There are maybe 5 million people with HepC in the USA alone, and Gilead is asking $84,000 each for its treatment. That's a total in Zuck's own back yard of more than a hundred times his £3 billion for just a single disease. It's not money that needed, it's an ethical approach to medicine.

Officials, lack of kit to blame for 'critical delays' in sex abuse inquiry

David Pollard

Watch out for the 30-year rule

Far better than homework-eating dogs or malfunctioning archives which misplace critical records and find them too late for use in court, this rule allows the police to block access to information in case files for thirty years. And the count is from the date that any action was taken in relation to the case.

It appears that even a cursory review will suffice to have the files closed for a further 30 years and thus continue to block Freedom of Information requests. If certain information they hold about crimes which have remained unsolved for decades were to be widely available this would, they say, make solving them and bringing the perpetrators to court more difficult.

EU ministers look to tighten up privacy – JUST KIDDING – surveillance laws

David Pollard

I for one argue against Jacob Ginsberg

"No one can argue with the fact that if intelligence agencies and the police were able to access and look inside all houses, they would catch more criminals."

Where you have policing by consent, the most significant part of crime control comes about through the co-operation and involvement of the general public. When the public's trust is broken this aspect of crime control is eroded. If the authorities invade people's privacy they will forfeit their co-operation and make policing less effective.

IT delays helped derail UK's historic child sexual abuse inquiry

David Pollard

It's not just cases of child sex abuse that they don't want to see reviewed.

Incidental aspects involving recreational drugs are, however, given continued attention.
