Something's missing in our universe: Boffins look into the SUPERVOID

David Pollard

Re: Yes, but

"Take all paths" - That's the problem. How can the photon's energy have more than one value?

Equally, how can the gravitational potential of a point in space be defined if it depends on which direction you choose to look?

Yes, but

Suppose there happened to be massive objects situated such that through gravitational lensing there were two (or more) paths available from wherever the photon started out in the distant past to a detector on Earth, one going through the less dense region the other(s) not. Depending on the path that the photon took, its energy would be different when it arrived.

I don't understand this at all

"The low mass helps explain the low observed temperature of the cold spot. Crossing the region, CMB photons lose energy ... Were the universe regular, those photons would recover energy from other mass exiting the region; the shortage of mass means the energy isn't recovered."

Imagine a photon traveling from afar and crossing a region of the universe where the density is different from the average. If this was a region where density is locally higher than average, the photon's energy would increase as it approaches and then decrease back towards its original energy as it moves back into the overall average density; as it 'climbs out' of the gravitational well. So why don't photons approaching a region of lower density lose energy as they approach and then gain it back again when they move away; as in going over a gravitational hillock?

Google drives a tenth of news traffic? That's bull-doodie, to use the technical term

David Pollard
Bronze badge

What sort of traffic?

Presumably there is a big difference between the number of visitors and the number of page views. With traffic to the Reg, for example, many of the visitors who start from a search engine will simply read the one page, in contrast to regular readers who are likely to take in several pages when they visit.

Re: 100% False Positive rate

Perhaps what's needed is an opportunity to log the details and check with a database/forum that other people have also seen the warning and/or that the owner is correcting the problem. That would go some way towards making the warnings meaningful to everyday users.

More than 260 suspects charged in UK child abuse crackdown

David Pollard

Re: "the biggest UK inquiry into people allegedly sharing child abuse images..."

Is it too cynical to wonder that these enquiries are being publicised partly to counter the leaks about cover-ups of sex crimes? Headlines of 'crackdown on child abuse' take attention away from the crimes committed by people in a position of power which are still not being fully investigated.

NHS England has some sneaky plans for Care.data acceleration

David Pollard

Said it before and will say it again

With respect to both accuracy and security it's not a good idea to have two copies of the data.

There seems to me to be no reason why data for large-scale surveys and research cannot be pre-processed locally at the GP, clinic and hospital level and the essentially anonymous results then collated nationally.

Boffinry listicle MADNESS: ONE THING you need to know about CHAMELEONS

David Pollard
Bronze badge

Re: "reflect a substantial proportion of the infrared"

It has to look good and be easy to fit and clean. I had wondered about using Pilkington's IR-reflective glass but that would be difficult to fit; especially as the stoves are already in place. A few layers of aluminium foil, crinkled to make airgaps and hidden behind the back, seems the best solution so far.

Chameleon wallpaper would be neat because it would turn red as it began to reflect, thus adding to perceived warmth.

"reflect a substantial proportion of the infrared"

For a while I've been wondering about how to improve the efficiency of wood-burning stoves that a couple of friends have installed; much of the radiant heat goes into the outside wall at the back. If someone can work out how to make chameleon wallpaper that withstands moderate temperatures this would fit the bill very nicely.

Re: IT Angle?

"only a super computer backed implementation can work it out"

The problem is more likely to be that in a social welfare system, especially one that involves disadvantaged people, sometimes an element of discretion is appropriate. This can be difficult to codify.

Decriminalisation

Perhaps if the government were to decriminalise recreational drug use this might lead to an even larger reduction in crime.

As to allowing secure and anonymous communications, isn't it the case that, although there are exceptions, generally the more trust you place in people the more trustworthy they become?

Policing by consent?

Plod took a photo of me when I was stopped for a defective tail lamp on my van.

The creation of databases by collecting pics at every opportunity makes 'armchair policing' easier while doing little to reduce crime. It erodes the main resource in tackling crime: public co-operation. To treat everyone who isn't a club member as a criminal does not improve things.

Re: Meanwhile, in associated news

It's good to see that an online equivalent is in fact available. Earlier in the day after following newspaper links there didn't seem to be one. It looks as though the NHS site doesn't show the online version to those who are browsing safely with scripts blocked.

NHS Scotland is not exactly secure

A quick check with Google for [site:nhs.uk paypal viagra] shows a link for

www.elib.scot.nhs.uk/portal/elib/Pages/LinkThroughChecker.aspx

which redirects to: http://www.trace-elements.org.uk/

The SHOW people, who are apparently responsible for "Putting Scotland's Health on the Web" don't provide a telephone number which would allow this to be reported. They do, however, provide a handy contact page for technical issues and feedback. This, when details are entered, comes up with: "The remote server returned an error: (403) Forbidden."

Meanwhile, in associated news

Today saw the launch of an "Offficial NHS Calculator" app which checks susceptibility to heart attack based on lifestyle questions. This is being promoted in several national newspapers. It's curious that although an anonymous web version would presumably be trivially easy to implement, the app is only accessible from mobile devices.

It's hard not to wonder whether details are being analysed and recorded against the mobile telephone number from which the app is accessed.

UK Supreme Court waves through indiscriminate police surveillance

What's the appropriate response to a vexatious PoH?

Judging by the responses here it would be useful to readers to know what the best response would be were one to be served with a PoH. Does one write to the Chief Constable and collate the obfuscatory replies that this is likely to generate, in order to be able to demonstrate a measure of vindictiveness/incompetence etc. should the document ever be used? Or does one lodge a complaint with the IPCC?

Might we have a comment from the experts at Liberty and similar organisations please?

Is there a cure for cancer sitting at the back of the medicine cabinet already?

David Pollard
Bronze badge

... not going to post an answer ....

Isn't this one of the reasons why we need to be pressing for open access publication of research, rather than letting it be hidden behind paywalls? Certainly there is a strong argument that anything which has been government funded should be open access.

While it may be slightly disconcerting for GPs and other health professionals that patients might sometimes know almost as much as they do, public education is both an important component of medicine and a means to ensure that Big Pharma is to some extent held to account.

Subscription for prescription?

The 'health news in return for your data' aspect seems more than a little ominous.

Are they planning a soft-sell promotion of care.data by partially integrating it with the BBC? Is there perhaps a plan to transfer NHS Choices to the Beeb's custody, with the costs of dispensing advice in this way being covered by the licence fee budget? Is some sort of incentives and rewards system envisaged, such as free access to certain programme streams, for those who don't opt out of care.data?

$250K: That's what Lenovo earned to RAT YOU OUT with Superfish

Changes at the Lenovo site

A couple of days ago the main driver download page on Lenovo's website was largely filled with an advert for a third party utility to scan and download the latest drivers. Presumably this would 'phone home to check every time the machine was booted up. Although initially free, it looked as though $39.95 came into the picture somewhere along the line with another $9.95 for annual subscriptions.

Now there is no mention of this bloatware. Driver details are presented much more cleanly; there is an option to show all the appropriate drivers for a given operating system on a single page. Linux versions aren't yet provided, but one can hope.

The scanner which had been being promoted there now appears to be on 'special offer' on its own site, discounted to $29.95.

Microsoft loosened it's grip on win7 install media?

Until last week it had been possible simply to download Win 7 ISOs from Digital River. These would install and authenticate normally using an OEM key; well, certainly this worked with HP machines and licences. Now the Digital River downloads have been stopped and only those who have a key from a full retail copy are able download the ISO, after first registering their key with Microsoft. Those who bought a machine with Windows 7 already installed are instructed to contact the manufacturer if they wish to obtain an ISO, even though their key is valid.

Far from loosening its grip, Microsoft has made it impossible for the majority of users to download a Windows 7 ISO.
