Dog owners can sleep easy tonight because physicists have discovered how rapidly a wet dog should oscillate its body to dry its fur. Presumably, dogs already know. From the article: "Today we have an answer thanks to the pioneering work of Andrew Dickerson at the Georgia Institute of Technology in Atlanta and a few buddies. But more than that, their work generates an interesting new conundrum about the nature of shaken fur dynamics. Dickerson and co filmed a number of dogs shaking their fur and used the images to measure the period of oscillation of the dogs' skin. For a labrador retriever, this turns out to be 4.3 Hz."

Zarrot writes "Turbine has listened to the community and backed away from the partnership with SuperRewards that we discussed yesterday. Quoting: 'Based on your feedback, we're stepping away from the "Offer" category for now. We'll keep exploring alternate ways for players who want points to get them. We'll also continue to innovate in pricing and accessibility because that's who we are. As of today, the Offer Wall is coming down. We'll collect all the feedback we've received over the last few days and will use it to guide future decisions.'"

A post on Pixel Poppers looks at the psychological underpinnings of the types of challenges offered by different game genres, and the effect those challenges have on determining which players find the games entertaining. Quoting: "To progress in an action game, the player has to improve, which is by no means guaranteed — but to progress in an RPG, the characters have to improve, which is inevitable. ... It turns out there are two different ways people respond to challenges. Some people see them as opportunities to perform — to demonstrate their talent or intellect. Others see them as opportunities to master — to improve their skill or knowledge. Say you take a person with a performance orientation ('Paul') and a person with a mastery orientation ('Matt'). Give them each an easy puzzle, and they will both do well. Paul will complete it quickly and smile proudly at how well he performed. Matt will complete it quickly and be satisfied that he has mastered the skill involved. Now give them each a difficult puzzle. Paul will jump in gamely, but it will soon become clear he cannot overcome it as impressively as he did the last one. The opportunity to show off has disappeared, and Paul will lose interest and give up. Matt, on the other hand, when stymied, will push harder. His early failure means there's still something to be learned here, and he will persevere until he does so and solves the puzzle."

We discussed Microsoft making IE8 a critical update a while back; but then the indication was that the update gave users a chance to choose whether or not to install it. Now I Don't Believe in Imaginary Property writes in with word that the update not only does not ask, but it makes IE the default browser. "Microsoft has a new tactic in the browser wars. They're having the 'critical' IE8 update make IE the default browser without asking. Yes, you can change it back, but it doesn't ask you if you want IE8 or if you want it as the default browser, it makes the decisions for you. Opera might have a few more complaints to make to the EU antitrust board after this, but Microsoft will probably be able to drag out the proceedings for years, only to end up paying a small fine. If you have anyone you've set up with a more secure alternative browser, you might want to help check their settings after this."

vigmeister writes "I hopped on the netbook bandwagon early this year in a rather odd fashion by picking up an outdated portable tablet (Fujitsu P1510) which just about matches the latest, greatest netbooks for their performance and portability features, while nipping them by managing to give me a better battery life. I've been happy using XP Tablet on this machine until recently, when I started thinking that by optimizing the OS for targeted use, I may be able to squeeze more out of the device. So, my questions are: What OS would you recommend for a netbook/outdated laptop? Usage is typically light — web surfing (with multimedia), email, word processing, spreadsheet and reading PDFs. Also, what OS would you recommend for a ultraportable tablet? Usage is similar to a netbook; there's a little more document editing going on, and good handwriting recognition and note-taking software would be great."
