MojoKid writes "From October to December, the advertising departments of a thousand companies exhort children to beg, cajole, and guilt-trip their parents for all manner of inappropriate digital entertainment. As supposedly informed gatekeepers, we sadly earthbound Santas are reduced to scouring the back pages of gaming review sites and magazines, trying to evaluate whether the tot at home is ready for Big Bird's Egg Hunt or Bayonetta. Luckily, The New York Times is here to help. In a recent article provokingly titled 'Ten Games to Cross off Your Child's Gift List,' the NYT names its list of big bads — the video games so foul, so gruesome, so perverse that we'd recommend you buy them immediately — for yourself. Alternatively, if you need gift ideas for the surly, pale teenager in your home whose body contains more plastic then your average d20, this is the newspaper clipping to stuff in your pocket. In other words, if you need a list like this to understand what games to not stuff little Johnny's stocking with this holiday season, you've got larger issues you should concern yourself with. We'd suggest picking up an auto-shotty and taking a few rounds against the horde — it's a wonderful stress relief and you're probably going to need it."

Reservoir Hill writes "The Guardian reports that a study by Ed H Chi demonstrates that the character of Wikipedia has changed significantly since Wikipedia's first burst of activity between 2004 and 2007. While the encyclopedia is still growing overall, the number of articles being added has reduced from an average of 2,200 a day in July 2007 to around 1,300 today while at the same time, the base of highly active editors has remained more or less static. Chi's team discovered that the way the site operates had changed significantly from the early days, when it ran an open-door policy that allowed in anyone with the time and energy to dedicate to the project. Today, they discovered, a stable group of high-level editors has become increasingly responsible for controlling the encyclopedia, while casual contributors and editors are falling away. 'We found that if you were an elite editor, the chance of your edit being reverted was something in the order of 1% — and that's been very consistent over time from around 2003 or 2004,' says Chi. 'For editors that make between two and nine edits a month, the percentage of their edits being reverted had gone from 5% in 2004 all the way up to about 15% by October 2008. And the 'onesies' — people who only make one edit a month — their edits are now being reverted at a 25% rate.' While Chi points out that this does not necessarily imply causation, he suggests it is concrete evidence to back up what many people have been saying: that it is increasingly difficult to enjoy contributing to Wikipedia unless you are part of the site's inner core of editors. Wikipedia's growth pattern suggests that it is becoming like a community where resources have started to run out. 'As you run out of food, people start competing for that food, and that results in a slowdown in population growth and means that the stronger, more well-adapted part of the population starts to have more power.'"

F4_W_weasel sends us to the BBC for news of the eighth lone neutron star ever discovered. It has no associated supernova remnant, binary companion, or radio pulsations. It's in our stellar neighborhood, at most 1,000 light years away. The object emits all its radiation (as far as wa can detect with current instruments) in X rays. The object is called Calvera, after the bad guy in The Magnificent Seven — which is itself the collective nickname for the seven such objects previously known.
