Comment: Chemcially feasible? (Score 1) 143

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...

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.

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."

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.

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.

How long do you think it'll take for you to bleed to death if I shoot you with a pistol? Its not an easy problem to predict. You don't know precisely where you will be shot, if the bullet will go straight through or lodge in bone, or ricochet. You don't know how long your blood will take to clot. You can be pretty sure that, left unattended, you will die from being shot. But predicting exactly how long you will have is rather hard. CO2 levels cause global warming by basic physics, just as a greenhouse is warmer inside than outside. You trap the heat in, but let the visible light through. What the exact consequences of a certain CO2 level are is hard to say preciously, but if CO2 levels keep going up and up and up you can be sure that the polar ice caps are going to melt and sealevels are going to rise dramatically. Precisely when this will happen is as hard to predict as how long it'll take you to bleed out from a gunshot wound, but you wouldn't argue that because its hard to determine how long you have, it's not worth trying to avoid getting shot!

From the actual article: 1)This is no longer in operation, it was only running for a couple of weeks in the constant cat-and-mouse game with cheat developers 2)It was targeted at the DNS for DRM servers which cheat authors used to SELL cheats to PAYING customers. The system simply reported if the MD5 hash matched the DNS for the known cheat DRM servers, once the cheat had been detected during gameplay already. The DRM servers were not running a website.

All of Android is open source, except Google Play/Market, Gmail app, Google Maps, etc If you want your phone to have the Google App store, then you need to obey their terms and conditions. Just because the OS is open source doesn't mean any program which runs on it has to be. There are plenty of non GPL programs available for Linux! An android phone WITHOUT access to Google app store, Google Maps, Calender, Gmail etc isn't going to be much use to the majority of Android users. This is how Google controls Android.
