In particular, the part that forbids distributing 'any Product whose primary purpose is to facilitate the distribution of Products outside of the Market.' As Kongregate's Jim Greer explained to Joystiq, the app is essentially a custom web browser that loads in a Flash game from the mobile version of Kongregate. Plus, it will cache the game so you can play offline. And this may be the feature that got it yanked, speculates Ryan Kim at GigaOm."

Researchers from Rice University have found a type of amoeba that practices a sort of "primitive farming behavior." When their bacteria food become scarce, the Dictyostelium discoideum will group together and form a "fruiting body" that will disperse bacteria spores to a new area. From the article: "The behavior falls short of the kind of 'farming' that more advanced animals do; ants, for example, nurture a single fungus species that no longer exists in the wild. But the idea that an amoeba that spends much of its life as a single-celled organism could hold short of consuming a food supply before decamping is an astonishing one. More than just a snack for the journey of dispersal, the idea is that the bacteria that travel with the spores can 'seed' a new bacterial colony, and thus a food source in case the new locale should be lacking in bacteria." It's good to know that even a single celled creature is not immune to the pull of Farmville.

An anonymous reader writes with this excerpt from Significant Bits about how the early level design in Super Mario Bros. 3 gradually introduced players to the game without needing something as blatant and obtrusive as a tutorial: "Super Mario Bros. 3 contains many obvious design lessons that are also present in other games, e.g., the gradual layering of complexity that allows players to master a specific mechanic. What surprised me during my playthrough, though, was how some of these lessons were completely optional. The game doesn't have any forced hand-holding, and it isn't afraid of the player simply exploring it at his own pace (even if it means circumventing chunks of the experience)."

crabel writes with this quote from the H Online: "At the 27th Chaos Communication Congress in Berlin security researcher Julia Wolf pointed out numerous, previously hardly known security problems in connection with Adobe's PDF standard. For instance, a PDF can reportedly contain a database scanner that becomes active and scans a network when the document is printed on a network printer. Wolf said that the document format is also full of other surprises. For example, it is reportedly possible to write PDFs which display different content in different operating systems, browsers or PDF readers — or even depending on a computer's language settings."
