Beware the Garden of Steven 580

theodp writes "With its forthcoming Lion Mac OS and new Apple-curated Mac Apps Store, Apple will be locking down top tier applications on the Mac similar to the way apps are locked down on the iPad and iPhone. Only by submitting their apps to Apple's store and giving up 30% of their receipts will developers get to take advantage of two new OS features. The first is Apple's new 'Launchpad,' a tool for easily opening application; the second is the ability to update apps to new versions with one click. It will be a lot easier to use apps bought from the Mac App Store than ones downloaded in the wild. It didn't have to be that way, says Valleywag's Ryan Tate: 'Apple could have enabled its Launchpad and auto-update features for all applications, sold through the Apple Store or not. For example, an open system for updating applications has been in use for years on Ubuntu... Ubuntu's 'Apt' (Advanced Packaging Tool) lets users install, update, and remove software of their choosing with a single command. There's a central list of apps curated by Ubuntu's maintainers, but users are free to add and install from other lists... But Apple seems to have made a very clear choice not to take the open route.' Longtime Apple developer Dave Winer was also concerned, tweeting during Apple's presentation 'Is this the end of the Mac as an open platform?' The news also prompted developer Anil Dash to call for an open alternative to the Mac App Store."

Israeli Scientists Freeze Water By Warming It 165

ccktech writes "As reported by NPR and Chemistry world, the journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky [note: abstract online; payment required to read the full paper] of Israel's Weizmann Institute, who have figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a positively charged surface. By putting water on the pyroelectric material Lithium Tantalate, which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to -17 degrees C., and then freeze when the substrate and water were warmed up and the charge changed to positive, where water freezes at -7 degrees C."

Comment shopping carts are just setup wrong (Score 1) 388

They state that the retailers are frustrated and confused by buyers exiting out of shopping carts and then returning, but they setup the shopping cart such that you can't know the final price of the purchase without entering the shopping cart to a certain point. If you are a comparison shopper, what's the point of comparing prices if you don't have the "final" price to compare against?
