SpaceX Tests Its Raptor Engine For Future Mars Flights (techcrunch.com) 92

Thelasko writes: Elon Musk is preparing to unveil his plans to colonize Mars at the 67th annual International Astronautical Congress tomorrow. As a tease to his lecture, he has released some details about the Raptor engine on Twitter, including pictures. Mr. Musk states that, "Production Raptor coal is specific impulse of 382 seconds and thrust of 3 MN (~310 metric tons) at 300 bar." He goes on to note that the specific impulse spec is at Mars ambient pressure. The Raptor interplanetary engine is designed for use with Space X's Mars Colonial Transporter craft. Musk notes that the "chamber pressure runs three times what's present in the Merlin engine currently used to power Falcon 9," according to TechCrunch. "Merlin has specific impulse of 282 seconds (311 seconds in the vacuum of space), and a relatively paltry 654 kilonewton (0.6 MN) at sea level, or 716 kN (0.7 MN) in a vacuum. You can view a picture of the "Mach diamonds" here, which are visible in the engine's exhaust.

It is hard to see how nuclear subsidies help with climate. By the time plants are built, electricity will be too cheap for them to opperate even with subsidies. Solar and wind subsidies are responsible for lowering the cost of electricity by encouraging scale, so why waste money on nuclear subsidies at all?

ISP To FCC: Using The Internet Is Like Eating Oreos (consumerist.com) 182

New submitter Rick Schumann shares with us a report highlighting an analogy presented by an ISP that relates Double Stuf Oreos to the internet. Specifically, that Double Stuf Oreos cost more than regular Oreos, and therefore you should pay more for internet: The Consumerist reports: "Ars Technica first spotted the crumbly filing, from small (and much-loathed) provider Mediacom. Mediacom's comment is in response to the same proceeding that Netflix commented on earlier this month. However, while Netflix actually addressed data and the ways in which their customers use it, Mediacom went for the more metaphor-driven approach. The letter literally starts out under the header, 'You Have to Pay Extra For Double-Stuffed,' and posits that you, the consumer, are out for a walk with $2 in your pocket when you suddenly develop a ferocious craving for Oreo cookies." Of course their analogy is highly questionable, since transmitting data over a network doesn't actually consume anything, now does it? You eat the cookie, the cookie is gone, but you transmit data over a network, the network is still there and can transmit data endlessly. Mediacom's assertion that the Internet is like a cookie you eat, is like saying copying a file on your computer somehow diminishes or degrades the original file, which of course is ridiculous.

After the CD stunt they pulled the same shit with their USB sticks. I think that was just a few years after the CD incident so there are probably more instances.
Don't buy a Sony.

I fully buycutted them for 15 years, but had to pardon them recently to buy a compact flagship cellphone, they were literally the least evil, all other options had done MUCH MUCH worse, and more recently. At least as far as I know, which is why I am interested in whether they did it recently.

Wow, 100.. That makes it less likely than winning the lottery.

Students are trained to beat the test (i.e., always having the right answer), which inhibits risk-taking because they don't want to be failures. Students who are already considered failures by the education system aren't afraid to take risks. You can't succeed in business unless you're willing to take risk and hire people smarter than you.

Depends on where you go to school, and what you expect to get from it. But all studies show that education is one of the strongest links to success that exist, and lack of education one of the strongest correlations of failure and poverty. Now statistics isn't logic, but it sure does show the majority of the well educated does better than the majority of drop outs.

HERE, Automakers team up to provide us something we've had for 10 years already from several other sources.

Thanks Automakers, good to see you're on the cutting edge of technology yet again!

You have had it for over 10 years from HERE (formaly also known as Navteq). This is not new to them, they are one of the primary providers of this service, this is just a new addtion to the service.

The map display in a Tesla already shows traffic congestion. I have heard that they get the data from aggregate cell phone data. The cell towers can tell when the cellphones bunch up and stop moving.

They get it the same place everybody else gets it, by being it from third parties, probably HERE or similar companies depending on where they bought their GPS software.


California Enacts Law Requiring IMDb To Remove Actor Ages On Request (hollywoodreporter.com) 274

California Gov. Jerry Brown on Saturday signed legislation that requires certain entertainment sites, such as IMDb, to remove -- or not post in the first place -- an actor's age or birthday upon request, reports Hollywood Reporter. From the report: The law, which becomes effective Jan. 1, 2017, applies to entertainment database sites that allow paid subscribers to post resumes, headshots or other information for prospective employers. Only a paying subscriber can make a removal or nonpublication request. Although the legislation may be most critical for actors, it applies to all entertainment job categories. "Even though it is against both federal and state law, age discrimination persists in the entertainment industry," Majority Leader Ian Calderon, D-Whittier, said in a statement. "AB 1687 provides the necessary tools to remove age information from online profiles on employment referral websites to help prevent this type of discrimination."Bloomberg columnist, Shira Ovide said, "Congratulations, IMDB. You have now become the subject of California law." Slate writer Will Oremus added, "Sometimes I start to think California is not such a bad place and then they go and do something like this."

Google Is Planning a 'Pixel 3' Laptop Running 'Andromeda' OS For Release in Q3 2017 (androidpolice.com) 55

Google plans to launch a laptop next year with Pixel branding which will run 'Andromeda' operating system, reports AndroidPolice, citing sources. Andromeda is a hybrid of Android and Chrome OS, the report adds. Pixel, Chrome OS and Android teams have been working on this project, dubbed Bison, for years, apparently. From the report: Bison is planned as an ultra-thin laptop with a 12.3" display, but Google also wants it to support a "tablet" mode. It's unclear to us if this means Bison will be a Lenovo Yoga-style convertible device, or a detachable like Microsoft's Surface Book, but I'm personally leaning on the former given how thin it is. Powering it will be either an Intel m3 or i5 Core processor with 32 or 128GB of storage and 8 or 16GB of RAM. This seems to suggest there will be two models. It will also feature a fingerprint scanner, two USB-C ports, a 3.5mm jack (!), a host of sensors, stylus support (a Wacom pen will be sold separately), stereo speakers, quad microphones, and a battery that will last around 10 hours. The keyboard will be backlit, and the glass trackpad will use haptic and force detection similar to the MacBook. Google plans to fit all of this in a form factor under 10mm in thickness, notably thinner than the aforementioned Apple ultraportable.The report, however, adds that it is likely that Google might revise the specifications by the time of its launch, which is slated to happen sometime in Q3 2017.

Moving Beyond Flash: the Yahoo HTML5 Video Player (streamingmedia.com) 94

Slashdot reader theweatherelectric writes: Over on Streaming Media, Amit Jain from Yahoo has written a behind-the-scenes look at the development of Yahoo's HTML5 video player. He writes, "Adobe Flash, once the de-facto standard for media playback on the web, has lost favor in the industry due to increasing concerns over security and performance. At the same time, requiring a plugin for video playback in browsers is losing favor among users as well. As a result, the industry is moving toward HTML5 for video playback...

At Yahoo, our video player uses HTML5 across all modern browsers for video playback. In this post we will describe our journey to providing an industry-leading playback experience using HTML5, lay out some of the challenges we faced, and discuss opportunities we see going forward."

Yet another brick in the wall? YouTube and Twitch have already switched to HTML5, and last year Google started automatically converting Flash ads to HTML5.

Scientists Study How Non-Scientists Deny Climate Change (theguardian.com) 630

A new research paper suggest climate change opponents are "simulating coherence by conspiracism". Slashdot reader Layzej says the paper "examines this behavior at the aggregate level, but gives many examples where contradictory ideas are held by the same individual, and sometimes are presented within a single publication." From the paper: Claims that the globe "is cooling" can coexist with claims that the "observed warming is natural" and that "the human influence does not matter because warming is good for us". Coherence between these mutually contradictory opinions can only be achieved at a highly abstract level, namely that "something must be wrong" with the scientific evidence in order to justify a political position against climate change mitigation...

In a nutshell, the opposition to greenhouse gas emission cuts is the unifying and coherent position underlying all manifestations of climate science denial... Climate science denial is therefore perhaps best understood as a rational activity that replaces a coherent body of science with an incoherent and conspiracist body of pseudo-science for political reasons and with considerable political coherence and effectiveness.

"I think that people who deny basic science will continue to do so, no matter how contradictory their arguments may be," says one of the paper's authors, who suggests that the media should be wary of self-contradicting positions.

Please point me to one person in the past 100 years that achieved success with exactly no education at all and no help from anyone else.

A successful person doesn't have to be the smartest person in the room. Here's a list of 100 entrepreneurs who succeeded with little or no education, including a half-dozen who dropped out of elementary school.
