schwit1 writes: Scientists have found that, despite a complete ban since 2007, ozone-depleting chemicals are still being pumped into the atmosphere from some unknown source. "Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012. However, the new research shows worldwide emissions of CCl4 average 39 kilotons (about 43,000 U.S. tons) per year, approximately 30 percent of peak emissions prior to the international treaty going into effect. "We are not supposed to be seeing this at all," said Qing Liang, an atmospheric scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study published online in the Aug. 18 issue of Geophysical Research Letters, a journal of the American Geophysical Union. "It is now apparent there are either unidentified industrial leakages, large emissions from contaminated sites, or unknown CCl4 sources."

Today's videos are parts three and four of our casual interview with Tim O'Reilly, founder of O'Reilly Media and one of the most influential open source boosters around. (You supplied the questions. He supplied the answers.) We had a lot more to say about Tim yesterday when we ran parts one and two of our video interview with him.

An anonymous reader writes eBooks are great and wonderful, but as The Guardian reports, they might not be as good for readers as paper books. Results from a new study show that test subjects who read a story on a Kindle had trouble recalling the proper order of the plot events. Out of 50 test subjects, half read a 28-page story on the Kindle, while half read the same story on paper. The Kindle group scored about the same on comprehension as the control group, but when they were asked to put the plot points in the proper order, the Kindle group was about twice as likely to get it wrong.

So, is this bad news for ebooks? Have we reached the limits of their usefulness? Not necessarily. While there is evidence that enhanced ebooks don't enhance education, an older study from 2012 showed that students who study with an e-textbook on an ebook reader actually scored as well or higher on tests than a control group who did not. While that doesn't prove the newer research wrong, it does suggest that further study is required. What has your experience been with both recall and enjoyment when reading ebooks?

The results (PDF) were a bit eye-opening since the report's recommendations don't favor Firefox as a baseline for Tor, rather Google Chrome. But Tor's handlers concede that budget constraints and Chrome's limitations on proxy support make a switch or a fork impossible.

Digia has announced that existing Qt modules will now be covered under the LGPLv3 in addition to the LGPLv2.1, GPLv3, and the enterprise (proprietary) license. New modules will be dropping LGPLv2.1 and GPLv3+ and be released under the LGPLv3 and GPLv2+ instead. This should be a good move: new Qt modules will be Apache license compatible, LGPLv3 code can trivially be converted to GPLv3, and Digia is even releasing a few modules it intended to make proprietary as Free Software. The KDE Free Qt Foundation is on board. The move was made because of device vendors exploiting a loophole in the GPLv2/LGPLv2.1 that denied users the right to modify Qt or write their own applications. Digia has some self-interest as well, since those vendors were exploiting the tivoization loophole to avoid buying enterprise licenses. From the announcement: We also consider locked-down consumer devices using the LGPL’ed version of Qt to be harmful for the Qt ecosystem. ... Because of this, we are now adding LGPL v3 as a licensing option to Qt 5.4 in addition to LGPL v2.1. All modules that are part of Qt 5.3 are currently released under LGPL v2.1, GPL v3 and the commercial license. Starting with Qt 5.4, they will be released under LGPL v2.1, LGPL v3 and the commercial license. ... In Qt 5.4, the new Qt WebEngine module will be released under LGPL v3 in the open source version and under a LGPLv2.1/commercial combination for Qt Enterprise customers. ...

Adding LGPLv3 will also allow us to release a few other add-ons that Digia before intended to make available solely under the enterprise license. ... The first module, called Qt Canvas3D, will give us full WebGL support inside Qt Quick. ... The second module is a lightweight WebView module ... There is a final add-on that will get released under LGPL v3. This module will give native look and feel to the Qt Quick Controls on Android. This module can’t be released under LGPL v2.1, as it has to use code that is licensed under Apache 2.0, a license that is incompatible with LGPL v2.1, but compatible with LGPL v3.

jrepin (667425) writes Version 3.3 of Kolab.org, a free and open source groupware solution, has been released. It is now possible to add tags to email messages, work with notes right in the webclient, and manage your resources more easily. Kolab.org 3.3 introduces a new folder navigation view that allows you to search and subscribe to shared calendars, address books, task lists etc. directly from within the respective view. The calendar got a quickview mode which allows you to open an undistorted view on a single calendar. The user interface can now be fully operated with the keyboard and has support for screen readers as well as voice output as suggested by the WCAG 2.0 Guidelines and WAI ARIA standards.

walterbyrd sends this story from Vox: Everyone agrees that there's been an explosion of patent litigation in recent years, and that lawsuits from non-practicing entities (NPEs) — known to critics as patent trolls — are a major factor. But there's a big debate about whether trolls are creating a drag on innovation — and if so, how big the problem is. A new study (PDF) by researchers at Harvard and the University of Texas provides some insight on this question. Drawing from data on litigation, R&D spending, and patent citations, the researchers find that firms that are forced to pay NPEs (either because they lost a lawsuit or settled out of court) dramatically reduce R&D spending: losing firms spent $211 million less on R&D, on average, than firms that won a lawsuit against a troll. "After losing to NPEs, firms significantly reduce R&D spending — both projects inside the firm and acquiring innovative R&D outside the firm," the authors write. "Our evidence suggests that it really is the NPE litigation event that causes this decrease in innovation."

Elledan writes: Federal investigators in California have requested that BrightSource — owner of thermal solar plants — halt the construction of more (and bigger) plants until their impact on wildlife has been further investigated. "Unlike many other solar plants, the Ivanpah plant does not generate energy using photovoltaic solar panels. Instead, it has more than 300,000 mirrors, each the size of a garage door. Together, they cover 1,416 hectares. Each mirror collects and reflects solar rays, focusing and concentrating solar energy from their entire surfaces upward onto three boiler towers, each looming up to 40 stories high. The solar energy heats the water inside the towers to produce steam, which turns turbines that generate enough electricity for 140,000 homes." The concentrated solar energy chars and incinerates the feathers of passing birds. BrightSource estimates about a thousand bird die this way every year, but an environmental group claims the real number is much higher.
