The Cloud Ate My Homework 305

theodp writes "Over at CNET, James Urquhart sings the praises of cloud computing, encouraging folks to 'really listen to what is being said, understand how the cloud is being used, and seriously evaluate how this disruptive model will change your projects, your organization, and even your career.' Fair enough. Over at the Google Docs Help Forum, some perplexed cloud computing users spent the month of November unsuccessfully trying to figure out why they've been zinged for inappropriate content. Among the items deemed inappropriate and unshareable include notes on Henry David Thoreau ('the published version of this item cannot be shared until a Google review finds that the content is appropriate'), homework assignments, high school yearbook plans, wishlists, documents containing botanical names for plants, a list of websites for an ecommerce class, and a list of companies that rent motorcycles in Canada. When it comes to support in the cloud, it kind of looks like you might get what you pay for."

The Psychology of Achievement In Playing Games 80

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."

New Theory of Gravity Decouples Space & Time 575

eldavojohn writes "Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. At high energies, it actually snips any ties between space and time, yet at low energies devolves to equivalence with the theory of General Relativity, which binds them together. The theory is gaining popularity with physicists because it fits some observations better than Einstein's or Newton's solutions. It better predicts the movement of the planets (in an idealized case) and has a potential to create the illusion of dark matter. Another physicist calculated that under Horava Gravity, our universe would experience not a Big Bang but a Big Bounce — and the new theory reproduces the ripples from such an event in a way that matches measurements of the cosmic microwave background."

Fair enough, but did you check on the flux of cosmic rays of this energy? It's 1 per square kilometer per century. Cosmic rays with 10^20 eV happen, but very infrequently. Obviously as you go lower in energy, the higher the flux, so particles that are significantly affected by the solar wind and earth's magnetic field dominate the cosmic ray spectrum. I never thought I could use this knowledge for anything, good to see I didn't waste 5 years of my life. Oh wait...
