The origamians have an interesting sub-solution. Provided that there are an even number of slices, and all slices contain the middle of the pizza, if we enumerate the slices, the total area of the even slices will equal the total area of the odd slices.
Not really, since the salt would need to be publicly known for Gravatar to work (and it would break any backwards compatibility to add it in now). This was a 'social engineering' attack, not a rainbow table lookup – it pieced the name together with common providers to find a matching MD5. Salt would just add a single extra step.
I believe it's exactly the same problem/attack as was brought up about MicroID in the past. The idea of Pavatar is a much better way to do this sort of avatar-finding (though the decentralisation comes with its own problems), since it relies on a public web address instead of a semi-private e-mail address.

re: "Personally, I think regulation has a place, but in moderation, where it makes sense. Unfortunately though, no regulation only works when people can regulate themselves, which doesn't appear to be reality."
Agreed but this only works when people are honest. Unfortunately there are quite a few lets say less than honest people around. You can mention almost any industry and you will have a fare share of people who are not honest.
Ok, that link does seem to have an air of truthiness to it so I guess I will have to stand corrected. At some point though I did read on one of the aviation sites (aviationweek or flightglobal or someplace like that) that the pilot in question had a habit of kicking the rudder around like crazy and was warned about it previously. If AA was actually training its pilots to do that on purpose then I'm glad they also have shitty service to go along with their poorly trained pilots and I had already given up flying with them.
If Childs' boss WAS authorized for the information by policy, and Childs honestly felt the boss would misuse the information for something illegal and/or was gunning for Childs, then his actions may or may not be justifiable in this case - he's going to have to produce some proof that his boss had an illegitimate purpose. That could be tough.
Especially considering the City and his (former?) colleagues have had 18 months to doctor and erase the actual evidence that would vindicate Child's. I hope he had copious copies of relevant information tucked away off site.
Compilation copyright is a somewhat ridiculous concept that has gained popularity recently. It's akin to saying that you own the copyright to the particular selection of packages and programs on a particular Linux distro or install CD, for instance.
Its valid copyright law.
So if you have have a collective (or compilation if you want to call it that) copyright on a selection of separately licensed copyrighted works, someone can take your collection and add, remove, or modify something (say, add there logo) and it becomes a seperate collection not covered by the original collective copyright.
Derivative works doent effect collective copyright, its a different type of copyright to copyrighted "works".
Both of the leaders for our main political parties are active church goers (wiki Kevin Rudd and Tony Abbott), and (at least) Tony Abbott is pro-life.
So... did you ever wonder, do garbagemen take showers before they go to work?
