carusoj writes "Squatting on domain names is nothing new, but Twitter has created a new opportunity for squatters, in the form of Twitter IDs. Writes Richard Stiennon: 'Is there evidence of Twitter squatting (squitting?) Let's check. Yup, every single-letter TwitID is taken ... How about common words? Garage, wow, war, warcraft, Crisco, Coke, Pepsi, Nike, and Chevrolet are all taken. My guess is that Twitter squatters have grabbed all of these in the hopes that they will be worth selling in the not too distant future. Of course the legitimate holders of brands can sue for them and Twitter can just turn them over if asked. But, because the investment and risk for the squatter is zero, you are going to see the rapid evaporation of available Twitter IDs.'"

The Canadian superhero Captain Copyright has finally expired, not due to pirates or to the passage of 50 years after the death of the author, but because "the current climate around copyright issues will not allow a project like this one to be successful." The cartoon was intended to provide an education in copyright law for children, but it became a focus for criticism when even the Canadian Library Association condemned it for lacking balance because it ignored issues like Fair Dealing (Canada's version of Fair Use). Personally, I was hoping we'd see them get sued by DC & Marvel, who claim to own the trademark on the word "superhero", and vanish in a puff of logic.

Cuts and bruises writes "Hacker Joanna Rutkowska has flagged a "very severe hole" in the design of Windows Vista's User Account Controls (UAC) feature. The issue is that Vista automatically assumes that all setup programs (application installers) should be run with administrator privileges — and gives the user no option to let them run without elevated privileges. This means that a freeware Tetris installer would be allowed to load kernel drivers. Microsoft's Mark Russinovich acknowledges the risk factor but says it was a 'design choice' to balance security with ease of use."
