An anonymous reader writes: Cory Doctorow has posted an account of what happened when tech culture blog Boing Boing got a federal subpoena over the Tor exit node the site had been running for years. They received the subpoena in June, and the FBI demanded all logs relating to the exit node: specifically, "subscriber records" and "user information" for everybody associated with the exit node's IP address. They were also asked to testify before a federal grand jury. While they were nervous at first, the story has a happy ending. Their lawyer sent a note back to the FBI agent in charge, explaining that the IP address in question was an exit node. The agent actually looked into Tor, realized no logs were available, and cancelled the request. Doctorow considers this encouraging for anyone who's thinking about opening a new exit node: "I'm not saying that everyone who gets a federal subpoena for running a Tor exit node will have this outcome, but the only Tor legal stories that rise to the public's attention are the horrific ones. Here's a counterexample: Fed asks us for our records, we say we don't have any, fed goes away."

An anonymous reader writes: A little over a month ago, Bill Gates made headlines when he decided to double down on his investments in renewable energy. Now, he's written an article for Quartz explaining why: "I think this issue is especially important because, of all the people who will be affected by climate change, those in poor countries will suffer the most. Higher temperatures and less-predictable weather would hurt poor farmers, most of whom live on the edge and can be devastated by a single bad crop. Food supplies could decline. Hunger and malnutrition could rise. It would be a terrible injustice to let climate change undo any of the past half-century's progress against poverty and disease — and doubly unfair because the people who will be hurt the most are the ones doing the least to cause the problem." He also says government is not doing enough to fund such research, and that energy markets aren't doing a good enough job of factoring the negative effects of carbon emissions.

dkatana writes: In an article for InformationWeek Charles Babcock notes that IBM has been hoarding patents on every aspect of cloud computing. They've secured about 1,200 in the past 18 months, including ~400 so far this year. "For those who conceive of the cloud as an environment based on public standards with many shared elements, the grant of these patents isn't entirely reassuring." Babcock says, and he adds: "Whatever the intent, these patents illustrate how the cloud, even though it's conceived of as a shared environment following public standards, may be subject to some of the same intellectual property disputes and patent trolling as earlier, more directly proprietary environments."

An anonymous reader writes: When the shipping deadline was approaching for The Witcher 3, designer Matthew Steinke knew there was a big part of the game still missing: its economy. A game's economy is one of the things that can make or break immersion — you want collection and rewards to feel progressive and meaningful. Making items too expensive gives the game a grindy feel, while making them too cheap makes progression trivial. At the Game Developers Conference underway in Germany, Steinke explained his solution.

"Steinke created a formula that calculated attributes like how much damage, defense, or healing that each item provided, and he placed them into an overall combat rating could be used to rank other items in the system. ... Steinke set about blending the sub-categories into nine generalized categories, allowing him to determine the final weighting for damage and the range of prices for each item. To test if it all worked, he used polynomial least squares (a form of mathematical statistics) to chart each category's price progression. The resultant curve (pictured below) showed the rate at which spending was increasing as the quality of each item approached the category's ceiling value."

An anonymous reader writes: Tech Crunch reports that Amazon quietly rolled out changes to how their Prime subscriptions can be shared. The good news is that existing members aren't immediately losing their current sharing setups. It used to be that Amazon would let Prime subscribers share free shipping and a few other benefits with up to four other "household" members, with little restriction on what counted as a "household." The bad news: as of last weekend, Amazon now limits sharing to one other adult and four "child" profiles. The adults will need to authorize each other to use credit/debit cards associated with the account. Amazon didn't make any announcement about this, so it's unknown how long existing Prime shares will stay in effect. They could disappear when the subscription is up for renewal, or earlier if Amazon decides to crack down on it.

An anonymous reader writes: In October, Microsoft will publish Halo 5: Guardians, the first game in the series to be developed exclusively for the Xbox One. Microsoft is taking the opportunity to make a big play to become part of the e-sports market. They've announced a Halo competition with $1 million in prizes. As e-sports become more mainstream, and as game streaming has turned into a billion-dollar business, more and more development studios are seeing it as part of their marketing strategy. "When Halo fell out of favor among e-sports players, other games began to take off, often ones that were created with high-level competition in mind and that came from developers that invested heavily in events for professionals. Riot Games has turned League of Legends, its multiplayer online battle arena, into the most watched e-sport in the world, with 40,000 attendees at its finals in Korea last year." Microsoft wants back into that segment, and they're willing to spend big to do so.

New submitter IT.luddite sends word that Hasbro and Warner Bros. have announced Dungeons & Dragons will be getting its own film franchise. They already have a script, and they'll be working with production company Sweetpea Entertainment, but they haven't picked a director, yet. They'll have at least some of the people on board who worked on the D&D movie from 2000, which was a flop. The deal between Hasbro and Warner Bros. comes after a prolonged legal battle about who owned the rights to a D&D movie. They note, "All rights for future Dungeons & Dragons productions have been unified and returned to Wizards of the Coast, a wholly-owned subsidiary of Hasbro."

An anonymous reader writes: Yesterday we discussed Soylent, the artificial food substitute created by Rob Rhinehart and his team. As it turns out, this isn't Rhinehart's only unusual sustainability project. In a new post, he explains how he gave up on alternating current — a tough proposition for anyone living in the U.S. and still interested in using all sorts of modern technology. Rhinehart says, "Most power in the US is generated by burning coal, immediately squandering 67% of its energy, then run through a steam turbine, losing another 50%, then sent across transmission lines, losing another 5%, then to charge a DC device like a cell phone another 50% is lost in conversion. This means for 100 watts of coal or oil burned my phone gets a mere 16."

The biggest hindrance was the kitchen. As you might expect for the creator of Soylent, he doesn't cook, and was able to get rid of almost all kitchen appliances because of that. He uses a butane stove for hot beverages. He powers a small computer off batteries, which get their energy from solar panels. For intensive tasks, he remotes to more powerful machines. He re-wired his apartment's LED lighting to run off direct current. Have any of you made similar changes? How much of an effect does this really have?
