Signs of Water Found On Saturnian Moon Enceladus 79

Matt_dk writes "Scientists working on the Cassini space mission have found negatively charged water ions in the ice plume of Enceladus. Their findings, based on analysis from data taken in plume fly-throughs in 2008 and reported in the journal Icarus, provide evidence for the presence of liquid water, which suggests the ingredients for life inside the icy moon. The Cassini plasma spectrometer, used to gather this data, also found other species of negatively charged ions including hydrocarbons."

Drupal's Dries Buytaert On Drupal 7 55

itwbennett writes "The Drupal community has been working on Drupal 7 for two years, and there are 'hundreds of changes' to show for it, says Drupal creator Dries Buytaert in an interview with ITworld's Esther Schindler on the occasion of Drupal 7 going into Alpha test this week. Most notable for end users are 'some massive usability improvements,' says Buytaert, while site builders will see the greatest changes in the Drupal Content Construction Kit (CCK), which has been moved into the Drupal core. But one thing that hasn't changed is the not-so-easy upgrade path. 'The upgrade path for a Drupal site has never been really easy, to be honest,' Buytaert says. 'We do break backwards compatibility. It's a little bit painful because it requires all of the contributed modules — and there's 4,000-5,000 of them — to make changes.' But Buytaert doesn't think that's all bad. 'Innovation is key. Backwards compatibility limits innovation,' Buytaert contends. 'The rule we have is: We'll break the API if it makes a better API, and if it allows good innovation and progress to be made. Also: The second rule is that we'll never break people's data. We'll always provide an upgrade path for the data.'"

It's telling that Spring's press release uses more space extolling the virtues of its product than describing the situation behind the suit. It's also curious that the primary features it hypes "full Internet browsing while reading" and "interactive multi-media open Internet access", while the nook won't even have a Web browser. B&N basically says they might add one later, if the users want it. This is totally a wait and see situation, because right now it's not at all clear who the bad guy is.

Introducing the Warpship 361

astroengine writes "Dr. Richard Obousy, a guy who has put modern science into the warp drive, has designed his very own warpship. Now, for the first time, he's shared it with the world. It might not be the sleek Starship Enterprise, but its structure has been optimized to harness local 'dark energy,' generating a warp bubble so faster-than-light velocities are possible." Now, the only question is: will the ship achieve faster-than-light travel ... or will the company hit those speeds once it has enough money from investors?

Mostly, it's the publishers that control this. Rights are still parceled out on a regional basis and sold separately, even though the model is aged far beyond any practical meaning. World rights cost a lot more than, say, North American rights.

You're missing two things. Neither is guaranteed, but both are likely. One is that the economy of scale often kicks in very early on at the prototyping level. The error part of trial-and-error gets spread more thinly. The other is that part of the 1X cost includes R&D. Again, that cost gets spread more thinly at 5X.
