Proposed Penalty For UK Hackers Who "Damage National Security": Life

Grantbridge Re:Don't do the crime (164 comments)

What counts as "unauthorised" though? What if it's your job, but your boss gets you to do something which his boss didn't authorise. Was that authorised use of a computer system?

What if you use a false name on facebook and so breach the T+Cs, is that unauthorised use?

U.K. Supermarkets Beta Test Full-Body 3D Scanners For Selfie Figurines

Grantbridge Re:UK article, US units (159 comments)

Weight is normally KG now, I have no idea what my weight is in stone. Height is still probably more often in feet than cm. Weight or height of anything you buy is always in kg/m though.

U.K. Supermarkets Beta Test Full-Body 3D Scanners For Selfie Figurines

Grantbridge Re:UK article, US units (159 comments)

UK used to use Imperial measures, but now everything is metric with the exception of distances on road signs which are in miles. Milk and beer is normally sold in 568ml units, which happens to be the same as 1 pint!

American units are different, their pints are smaller (16 vs 20 fl.oz.)

First Demonstration of Artificial Intelligence On a Quantum Computer

Grantbridge Read the Paper, article is exagerating "Quahtum" (98 comments)

What they actually did if you read the paper is:

1) Encode a 6 or 9 image into 2 numbers, based on the number of excess pixels in the left vs right, and top vs bottom quadrants. From the article: After these preprocessing, the two printed image with standard font can be represented by ~x1= (0:9872;0:1595) for character "6" and ~x2= (0:3544;0:9351) for character "9"

2) Use a training algorithm to find the appropriate pulse sequence to give a up result from the molecule's NMR C13 spectra from a 6, and a down signal from a 9.

3) Run the NMR spectrum, feed in pulses based on the parameters produced from pixels encoded in a vector form like 1), get the result of "up" for a 6 and "down" for a 9.

It's certainly neat experimental NMR work, but I don't really see how it's quantum computing. But then maybe that's the NMR spectroscopist in me talking....

PETA Is Not Happy That Google Used a Camel To Get a Desert "StreetView"

Grantbridge PETA won't be happy until all animals are extinct (367 comments)

PETA don't like animals having any relationship with humans. They put down the vast majority of dogs they recieve rather than re-home them because they think that's more "humane" (and it's cheaper..)

They would rather you killed the camel and used a jeep to travel across the desert.

They are scum, and they won't be happy until there are no animals left on planet Earth except mankind.

For Now, UK Online Pirates Will Get 4 Warnings -- And That's It

Grantbridge Re:Illigal or not? (143 comments)

OK, I was referring to downloading a film. If you upload and seed a film the day before release, you could get prosecuted under 2A(b).

For Now, UK Online Pirates Will Get 4 Warnings -- And That's It

Grantbridge Re:Illigal or not? (143 comments)

It's never been criminal. But breaching copyright could get you sued by the copyright owner. The new system of warning letters is replacing a proposed "3 strikes" system where you would lose your internet access after 3 warnings, but with no accountability for being accusing of copyright infringement this was a stupid system.

The new one is simply sending warning letters to let people know they have been reported as infringing copyright, and so might want to be careful to avoid being sued in the future.

Mathematicians Solve the Topological Mystery Behind the "Brazuca" Soccer Ball

Yeah, you can make the ring, but how do you get it to be flat so they will fit into a sphere?

Mathematicians Solve the Topological Mystery Behind the "Brazuca" Soccer Ball

Grantbridge Chemcially feasible? (144 comments)

I can't see those 8 member flat rings being at all chemically feasible. I really don't think this is possible to make as a carbon molecule.

Aromatic rings need to have 6 or 10 electrons in the delocalised orbitals, so an 8 member ring is going to need to have some other elements/groups to be at all stable...

Football can mean either Rugby or Soccer. Since Rugby is short for Rugby Football, and Soccer is short for Association Football.

Torrentz.eu Domain Name Suspended

Grantbridge Re:Since when... (226 comments)

City of London Police are a very strange entity, since the Corporation of London isn't really a democratic body, and their police force should be viewed as serving the interests of their corporate masters, rather than the people at large. As such, I wouldn't obey any instruction from them without a court order.

Scientists Solve the Mystery of Why Zebras Have Stripes

Grantbridge Important Quote from Article (190 comments)

Relevant quotes missing from summary:

"researchers built horse mannequins, painted them in a variety of patterns, coated them with sticky stuff, and found that horseflies seemed to avoid landing on the fake horses that were painted with black and white stripes."

"The proposed explanation was that the flies preferred to land on dark surfaces. Such surfaces reflect the kind of polarized light that reminds the flies of the water or mud where they breed. Light surfaces aren't as attractive, but dark-and-light patterns are even worse — perhaps because such patterns confuse the flies' navigational sense."

Mt. Gox Shuts Down: Collapse Should Come As No Surprise

Grantbridge Transaction ID Bug (232 comments)

There was a bug in the code whereby you could get MtGox to send out your bitcoins to your address, but rebroadcast the transaction under a different transaction ID. This mean when MtGox checked to see if their transaction worked, it looked like it hadn't (since the transaction ID didn't match.) They then re-sent you the bitcoins you already had received, giving you twice as much as they should have.

Apparently the bug has been there for years.

It's like getting a cheque, and changing the cheque number from 123 to 124. The new cheque still looks valid so it cashes fine, but you go back to the sender and complain you never got a cheque. They see cheque 123 was never cashed, and so write you a new one. You cash that one as well. At some point they should notice that they've paid out twice as much as they should have, but for MtGox they didn't notice this for a long time.

How Well Do Our Climate Models Match Our Observations?

Grantbridge Re:The Worst Offender (560 comments)

Well the enclosed nature of a greenhouse certainly has the majority of the effect compared to letting the air simply escape. But the opaque to infra-red nature of glass provides insulation which lessens the heat loss at night. Its only a small effect compared to simply enclosing a space with rock-salt, but it still provides additional heating.

Bitcoin exchange operatores arrested, BitInstant now down

Grantbridge Grantbridge writes  |  about 9 months ago

Grantbridge (1377621) writes ""The Department of Justice said Robert Faiella, known as BTCKing, and Charlie Shrem from BitInstant.com have both been charged with money laundering.
The authorities said the pair were engaged in a scheme to sell more than $1m (£603,000) in bitcoins to users of online drug marketplace the Silk Road." from http://www.bbc.co.uk/news/tech...

It seems that BTCKing and Bitinstant have had people arrested over money laundering charges, and are now unavailable. If running an exchange counts as money laundering, then is the USA making itself a no-go area for bitcoin exchanges? Or will a reputable bank step up and run one complying with money laundering regulations."

Bitpint! Cambridge pub acepts Bitcoins as payment for pints(of real beer).

Grantbridge Grantbridge writes  |  about a year ago

Grantbridge (1377621) writes ""The Haymakers in Chesterton is now accepting digital currency Bitcoin for its wares — and all you need to pay your way is a virtual Bitcoin wallet and a QR reader.
Rob Curtis, one of the managers at the High Street pub, said the virtual currency was âoecatching onâ at the watering hole and fittingly for an online innovation, word has been getting around on Twitter."

You can now use your bitcoins to buy real beer in the Haymakers Pub in Cambridge (Chesterton). It doesn't mention how they control for the fluctuating exchange rate. The pub produces a QR code on the till you scan with your smartphone and make the payment that way. Is this the first pub to accept bitcoins for beer?"

LD_LIBRARY_PATH shenanigans with libstdc++

Grantbridge Grantbridge writes  |  about 6 years ago

Grantbridge (1377621) writes "I am running a SuSE 10.2 system, without root access. I had to install a new version of GCC (4.3.x) to be able to compile some c++ software. I installed this into a dir in my home directory, and added it to my LD_LIBRARY_PATH.

The software then compiles, but when I try to run it I get the error message: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found

so the program is using the default /usr/lib64 library rather than the newer one on the LD_LIBRARY_PATH. If I run ldd it shows that the software is using some new libraries in my home dir, but its not using it for all of them

I have been unable to find any solution to this, is there some obscure linux thing which prevents libstdc++.so.6 from being overridden by LD_LIBRARY_PATH?

I am not massively experienced with unix systems, so there is probably some very basic thing I have missed, but is rarely stated as its assumed to be too simple!

Many thanks!"
