An anonymous reader writes "The first large scientific study of how people respond to poor video quality on the Internet paints a picture of ever rising user expectations and the willingness to abandon ship if those expectations are not met (PDF). Some nuggets: 1) Some users are willing to wait for no more than 2 seconds for a video to start playing, with each additional second adding 6% to the abandonment rate. 2) Users with good broadband connectivity expect faster video load times and are even more impatient than ones on mobile devices. 3) Users who experience video freezing watch fewer minutes of the video than someone who does not experience freezing. If a video freezes for 1% of its total play time, 5% less of its total play time is watched, on average. 4) Users who experience failures when they try to play videos are less likely to return to the same website in the future. Big data was analyzed (260+ million minutes of video) and some cool new data analysis techniques used."

New submitter dreamstateseven tips this Postmedia News report: "A forensic software company has collected files on a million Canadians who it says have downloaded pirated content. The company, which works for the motion picture and recording industries, says a recent court decision forcing Internet providers to release subscriber names and details is only the first step in a bid to crack down on illegal downloads. 'The door is closing. People should think twice about downloading content they know isn't proper,' said Barry Logan, managing director of Canipre, the Montreal-based forensic software company."
SchrodingerZ writes "Captain Scott Kelly, brother of former commander Mark Kelly, will embark on the United States' longest manned space mission, set for 2015. Kelly and Russian cosmonaut Mikhail Kornienko will spend an entire year on the orbiting International Space Station. The mission will be a first for NASA's space program, but it is far from the world record. The longest recorded time in space was the 438-day mission of Russia's Valery Polyakov, working on the Mir Space Station, 1994-1995. Kelly, a decorated Navy captain, received degrees from State University of New York Maritime College and the University of Tennessee, and was the flight engineer for space station expedition 25, and commander of expedition 26 in 2010. 'Kornienko hails from Russia's Syzran, Kuibyshev, region and has worked in the space industry since 1986.' The yearlong study on humans working in space will launch from the Baikonur Cosmodrome in Kazakhstan, spring 2015."
MyFirstNameIsPaul writes "In an announcement dated Monday, Nov 26, 2012, Dublin-based InTrade stated 'that due to legal and regulatory pressures, InTrade can no longer allow U.S. residents to participate in our real-money prediction markets.' The Washington Post reports that the Commodity Futures Trading Commission filed a complaint in federal court against InTrade for 'illegally facilitating bets on future economic data, the price of gold and even acts of war,' demonstrating just how far the long arm of U.S. law can reach."
Nerval's Lobster writes "Netflix has released Hystrix, a library designed for managing interactions between distributed systems, complete with 'fallback' options for when those systems inevitably fail. The code for Hystrix—which Netflix tested on its own systems—can be downloaded at Github, with documentation available here, in addition to a getting-started guide and operations examples, among others. Hystrix evolved out of Netflix's need to manage an increasing rate of calls to its APIs, and resulted in (according to the company) a 'dramatic improvement in uptime and resilience has been achieved through its use.' The Netflix API receives more than 1 billion incoming calls per day, which translates into several billion outgoing calls (averaging a ratio of 1:6) to dozens of underlying systems, with peaks of over 100,000 dependency requests per second. That's according to Netflix engineer Ben Christensen, who described the incredible loads on the company's infrastructure in a February blog posting. The vast majority of those calls serve the discovery user interfaces (UIs) of the more than 800 different devices supported by Netflix."
An anonymous reader writes "Yesterday there was a rumor doing the rounds that Nintendo was set to release a brand new version of the Wii console called the Wii Mini. The new machine would be significantly smaller than the current Wii, is expected to ship with a Wii Remote Plus, Nunchuk, and Sensor Bar, and hopefully carries a much lower (sub-$100) price. Well, it looks as though this wasn't just a rumor. Best Buy Canada has it listed with an image on its front page and a December 7 release date." Also at PC Mag.
New submitter alexanderb writes "While DOOM 3 BFG Edition might not have blown most gamers' minds, it sure blew some hackers' minds by supporting the Oculus Rift head-mounted display. Now, id Software have put up the source code of the BFG Edition under the GPL in good time for the tentative Oculus Rift release date, 12/12/12."
ananyo writes "It is permanently covered by a massive cap of ice up to 27 metres thick, is six times saltier than normal sea water, and at 13 C is one of the coldest aquatic environments on Earth — yet Lake Vida in Antarctica teems with life. Scientists drilling into the lake have found abundant and diverse bacteria, including at least one new phylum (full paper (PDF)). The find increases the chances that life may exist (or have once existed) on planets such as Mars and moons such as Jupiter's Europa."
An anonymous reader writes "I'm one of the original founders of an open source company which offers a popular open source product (millions of downloads) targeted primarily to small businesses. We have been doing this for 10 years now and we fund the development of the open source product with the usual paid support services, custom development and addons, but over the last few years, we've noticed a troubling trend. Companies that have downloaded our product from one of the many free download sites have a question they want answered, so they call our support line. Once we politely explain the situation and that telephone support has a reasonable fee associated with it, more and more of them are becoming seriously irate, to the point of yelling, accusing us of fraud and/or scamming them. For some reason, they think a free product should have free telephone support as well, and if we don't offer free telephone support then it's not really a free product. These same people are then resorting to social media in an attempt to 'spread the word' with the same false accusations, which is starting to take its toll on our reviews, ratings, and in turn our bottom line. Does the Slashdot community have any suggestions on how we can reverse this trend? How do other open source companies handle similar situations?"
kfogel writes "Two thumbs up, and maybe a tentacle too, on Version Control with Git, 2nd Edition by Jon Loeliger and Matthew McCullough. If you are a working programmer who wants to learn more about Git, particularly a programmer familiar with a Unix-based development environment, then this is the book for you, hands down (tentacles down too, please)."

sturgeon writes "A report out this morning pegs Amazon with a whopping 14% share of all daily Internet users — almost twice the nearest competitor (Ebay). And this number does not include all shopping sites absorbed by the growing Amazon empire. The original report has interesting graphics comparing Amazon to other retailers like Best Buy."
In addition to founding Canonical Ltd., the Ubuntu Foundation, and funding the Freedom Toaster, Mark Shuttleworth is a space enthusiast. In April 2002 Mark became the second self-funded space tourist and the first African in space. He spent eight days participating in experiments on the International Space Station as part of his $20 million trip. Now he's ready to answer your questions. Ask him anything you like, but please limit yourself to one question per post.
Nerval's Lobster writes "This is the story of the comparison that just wasn't meant to be. It's a story of everything that can go wrong in the customer end of the software world, and some thoughts on what needs to be done, especially in an area known as Installers. I'm a software engineer with 25 years of experience, and for years I've wanted to point out some of the shortcomings of my own industry to help make it better for everyone involved—not only for the end-users, but also for the IT people who have to support the products; the salespeople who have to sell and later, possibly, apologize for the software; for the executives whose hands are tied because they don't have the technical knowledge to roll up their sleeves and help fix problems in the code; and for the programmers themselves who might get stuck with what some consider the absolute worst position for a programmer: maintenance of crappy code written by programmers who have long since left the organization."
