Wired's transportation editor just published what he's calling "Elon Musk's Christmas letter" touting the accomplishments of Musk's "family" of companies, "thanks to an anonymous tipster." (Though the story's photo caption suspiciously calls it "an absolutely real and totally not made up holiday message," and at the very bottom of the piece it's tagged as "satire" -- a word which also appears at the end of its URL.)

SpaceX (age 15) Man these companies grow up fast. SpaceX didn't just successfully launch its 12th resupply mission to the International Space Station this summer, it upped its ambitions with a pretty detailed plan for colonizing Mars. (OK, as long as it comes home for Thanksgiving and Christmas!) The scheme involves an Interplanetary Transport System the company calls the BFR, or Big Fucking Rocket (you wonder where they get their sense of humor!), which it will definitely have built in just five years.

Tesla (age 14) After promising to start deliveries of its affordable Model 3 sedan this summer, my little automaker went all the way to production hell to make it happen. And boy is the car a wonder, with its huge glass roof, innovative touchscreen interface (so long, dashboard), and all the acceleration you know to expect from Tesla. I'm sure the 400,000 people who have pre-ordered one will agree whenever they get theirs...!

OpenAI and Neuralink (ages 2, 1) I've always thought we should merge our brains with computers, and I'm so glad two of my youngest are dedicated to making it happen... Maybe it'll even find the time to help big brother Tesla with that AI chip it's making for Autopilot.

The Boring Company (age 1) Celebrated its first birthday this month...! Boring knows my views on public transit, and has reassured me these tunnels will be for fancy hyperloops and private cars on electric sleds, only...

So, my friends and fans, comrades and competitors, investors short and long, my best tidings. May your lives be as rich, electrifying, and ambitious as ours.
For its 13th resupply mission of the ISS on December 15th, (the real) SpaceX used a recycled rocket, and Friday (the real) Elon Musk jokingly tweeted a video of the weird trail left behind by SpaceX's latest rocket launch with the caption, "Nuclear alien UFO from North Korea." By late Saturday he'd posted an update. "Having a sinking feeling that most people actually do think it was aliens..."

"So strange that people often believe things inversely proportionate to the evidence."

Harvard computer science professor David J. Malan "is pretty amazing!" says long-time education-watcher theodp. And he's sharing a link to the online version of Malan's famous CS50 class, "if you can't pony up the estimated $63,025-a-year sticker price to take 'the quintessential Harvard (and Yale!) course' on campus."

KQED's education site "MindShift" reports: Malan's class attracts students who have never taken computer science before, as well as kids who have been coding a long time. His goal with this diverse group of learners is to create a community that's equal and collaborative. One way he does this is by asking students to self-identify by comfort level. Those groups become different section levels, and they sometimes get different homework, but harder assignments are not worth more credit. Malan said recently that the "less comfortable" group has dominated his 700-person course. "At the end of the day all students are treated with the same expectations," said Malan, speaking at the Building Learning Communities conference in Boston.

Students are graded based on each individual's growth; Malan and his team of teaching assistants don't use absolute measures when assigning grades. Instead, they look at scope, how hard the student tried, correctness, how right the work was, style, how aesthetic the code is, and design, which is the most subjective. When it's time to assign grades, Malan and his teaching fellows have lots of in-depth conversations about how each student has improved relative to where he or she started...
The course includes a tool that rewrites error messages to make them easier to understand, plus a code-checking tool which they're planning to open source. There's also a cloud-based IDE which "allows students to access their code from multiple locations," though students can also submit their code through GitHub. (The original submission complains that Harvard's students are "coddled.") But Malan says the class works partly because there's an intentionally social aspect to it -- including numerous teaching assistants holding office hours in public spaces and "the human structure within the course." Guest lecturers have even included Mark Zuckerberg and Steve Ballmer.

But all these technical details don't really capture the wild flavor of the course and all of its multimedia bells and whistles. Malan's fast-paced lectures often close with relevant clips from movies -- for example, a lecture on cryptography which ended with video from a movie you'd see "if you turn on your TV on December 24th."

Elon Musk has released photos of the Tesla Roadster he plans to send to space via a Falcon Heavy rocket. "The series of photos, posted to Instagram, show the Roadster attached to a fitting and placed between the two halves of the payload fairing that caps the rocket," reports The Verge. "The photos were posted just hours after a picture leaked on Reddit that showed a grainy view of the car being readied for its final ride." From the report: This will be the inaugural flight of the Falcon Heavy, a rocket that SpaceX has been planning for years. The successor to the Falcon 9 , it's essentially (and simply put) three boosters strapped together, all of which will add enough thrust to make it the most powerful rocket in the world. It will give SpaceX the ability to send bigger payloads to space while also helping the company push farther out into the Solar System. But SpaceX doesn't want to put a valuable payload on the very first flight, which even Musk has admitted could end (or begin) with an explosion. So the company plans to use a "dummy payload" instead. "Test flights of new rockets usually contain mass simulators in the form of concrete or steel blocks. That seemed extremely boring," Musk wrote on Instagram today. "Of course, anything boring is terrible, especially companies, so we decided to send something unusual, something that made us feel."

Comcast has been embroiled in a legal battle since 2016 regarding potentially deceptive business practices surrounding its "Service Protection Plan" -- a $6 a month program which covered almost nothing. But as an amended complaint recently filed by the Washington state attorney general alleges, Comcast didn't just dupe customers, it may have signed them up for the plan without their knowledge. From a report: You might expect such a plan to, uh, protect the service a customer is paying for, by decreasing or eliminating the cost of repairs in the event something goes haywire. Not so! The fine print of the program excludes in-wall wiring and some outdoor wiring. This led the attorney general to conclude that the plan "simply covers the technician visiting the customer's house and declaring that the customer's equipment is broken."

An anonymous reader shares a report: Wind power prices fell to its lowest and below the cheapest solar tariffs in the fourth round of auctions, putting more pressure on turbine makers as developers are expected to negotiate already-falling equipment prices. State-run Gujarat Urja Vikas Nigam Ltd. auctioned 500-megawatt of grid-connected projects at as low as Rs 2.43 (3.8 cents) a unit. That was quoted by Actis-backed Sprng Energy that bid for 197.5-megawatt capacity and KP Energy that won 30 MW. That's lower than the lowest solar power tariffs of Rs 2.44 a unit discovered in May and 8 percent lower than wind power prices discovered in earlier national auctions in October, according to Bloomberg New Energy Finance. A decline in auction tariffs will put the manufacturers under even more pressure to innovate and meet the price expectations of developers, Bloomberg New Energy Finance said. Falling tariffs may lead to discovery of even lower bids in the national wind auctions scheduled for January, it added. India aims to auction 28-gigawatt wind projects by March 2020 to take it closer to the total targeted capacity of 60 GW by 2022. That's part of the plan to install 175 GW renewable energy capacity by 2022.

Eloking quotes a report from New Atlas: SpaceX's Falcon Heavy rocket has been a long time coming. The successor to its Falcon 9 and the vehicle hoped to carry humans to Mars, this booster will be one of the most powerful ever. And we've just gotten our best look at it yet, with CEO Elon Musk tweeting out photos of an almost complete Falcon 9 Heavy in the hangar ahead of a planned maiden launch next month. The Falcon Heavy is essentially three Falcon 9 first stages rolled into one, with a second stage sat atop the middle one. The nine engine cores in each first stage work together to provide thrust equal to eighteen 747 aircraft, making it the most powerful rocket currently in operation and the most powerful since the Saturn V rocket last lifted off in 1973. In a series of tweets, Musk revealed that when the Falcon Heavy does lift off for the first time, it will do so from the same pad used by the Saturn V rocket at NASA's Kennedy Space Center. Musk has said recently that the Falcon Heavy will carry his own cherry-red Tesla Roadster as its first payload, but as an earlier tweet professing his love for floors has shown, it's not always easy to tell how serious he is about such matters.

"Amazon applied for an 'AmazonTube' trademark earlier this week, according to a filing found by TV Answer Man, as the company's public feud with Google over accessing YouTube content on Amazon's devices continues to escalate," reports The Verge. "While there's not a lot of information about what AmazonTube might be, based on the trademark application's description of 'providing non-downloadable pre-recorded audio, visual and audiovisual works via wireless networks on a variety of topics of general interest,' it sure sounds like a YouTube competitor." From the report: TechCrunch notes that Amazon has also applied for a trademark on "OpenTube," as well, which, if anything, is a more blatant name for what Google is looking to accomplish here. It's also not the first time that Amazon has been rumored to be working on its own, free video service -- earlier this year there were rumors that Amazon was planning a "freemium" version of Prime Video, although the company released a statement saying that it had no plans to do so.

Eric Schmidt will be stepping down as the executive chairman of Alphabet's board of directors and transitioning to a technical adviser, the company announced. He will continue to serve on the company's board. CNBC reports: Schmidt first joined Google as CEO in 2001, back when the company only had several hundred employees, and become its executive chairman 10 years later. He maintained that role when Google restructured to become Alphabet in 2015.

"Larry, Sergey, Sundar and I all believe that the time is right in Alphabet's evolution for this transition," Schmidt said in a statement. "The Alphabet structure is working well, and Google and the Other Bets are thriving. In recent years, I've been spending a lot of my time on science and technology issues, and philanthropy, and I plan to expand that work."

An anonymous reader shares a report: The FCC plans to fine Sinclair Broadcasting group more than $13 million for failing to make the required disclosures related to programming sponsored by a third party. It's the largest fine the FCC has ever proposed for violation of its ad disclosure rules, which require broadcasters to disclose who is paying for sponsored programming.

Amazon is planning to retire its Music storage subscription service, the plan that enabled Amazon customers to upload their own music to the company's servers. From a report: Amazon Music Storage subscription plans, which let users upload music from their Mac or PC and stream them alongside the in-app on-demand and radio options, will be accepted until Jan. 15, 2018. Then, the service will run until January 2019, when it will be removed entirely. As of Monday this week, free plans -- which allow for 250 songs to be stored in the cloud -- are no longer able to upload new music to their MP3 locker.

According to Recode, Walmart's startup incubator is experimenting with a cashier-less store concept called Project Kepler, which "aims to reimagine the in-store shopping experience with the help of technologies like computer vision." The goal is reportedly the "creation of physical stores that would operate without checkout lines or cashiers -- in a similar fashion to Amazon's futuristic Amazon Go store." From the report: The Project Kepler project focused on the future of in-store shopping is being led by Mike Hanrahan, the co-founder and former chief technology officer for Jet.com, multiple sources tell Recode. It is located in Hoboken, N.J., where Jet is based. A Project Kepler job listing for a "computer vision engineer" says that the role will involve creating a "best-in-class consumer experience in the physical retail space." Amazon's Go concept uses a combination of sensors and cameras to track what each store shopper takes off of shelves so it can automatically bill them for their purchase without their having to stop to pay on the way out. The store's launch has been severely delayed, however, with reports that the technology did not work well when the store was crowded. Walmart is envisioning a similar system that would potentially eliminate the need for cashiers in stores outfitted with the technology. Walmart has more than two million employees worldwide, many of whom work at checkout.

shanen writes: How many of you don't print much these days? What is the best solution to only printing a few pages every once in a while? Here are some dimensions of the problem...

Inexpensive printers: The cost of new printers is quite low, but how long can the printer sit there without printing before it dies? Lexmark and HP used to offer an expensive solution with integrated ink cartridges that also included new print heads, but... Should I just buy a cheap Canon or Epson and plan to throw it away in a couple of years, probably after printing less than a 100 pages?

Printing services: They're mostly focused on photos, but there are companies where you can take your data for printing. My main concerns here are actually with the costs and the tweaks. Each print is expensive because you are covering their overhead way beyond the cost of the printing itself. Also, most of the time my first print or three isn't exactly what I want. It rarely comes out perfectly on paper the first time.

Social printing: For example, are any of you sharing one printer with your neighbors via Wi-Fi? Do you just sneak a bit of personal printing onto a printer at your office? Do you travel across town to borrow your brother-in-law's printer?

An anonymous reader quotes a report from The Verge: Reddit users have noticed that Apple appears to be slowing down old iPhones that have low-capacity batteries. While many iPhone users have experienced perceived slowdowns due to iOS updates over the years, it appears that there's now proof Apple is throttling processor speeds when a battery capacity deteriorates over time. Geekbench developer John Poole has mapped out performance for the iPhone 6S and iPhone 7 over time, and has come to the conclusion that Apple's iOS 10.2.1 and 11.2.0 updates introduce this throttling for different devices. iOS 10.2.1 is particularly relevant, as this update was designed to reduce random shutdown issues for the iPhone 6 and iPhone 6S. Apple's fix appears to be throttling the CPU to prevent the phone from randomly shutting down. Geekbench reports that iOS 11.2.0 introduces similar throttling for low iPhone 7 low-capacity batteries.

When reached for comment, Apple basically confirmed the findings to The Verge, but disputes the assumed intention: "Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components. Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions. We've now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future."

An anonymous reader writes: Canonical has temporarily pulled the download links for Ubuntu 17.10 "Artful Aardvark" from the Ubuntu website due to ongoing reports of some laptops finding their BIOS corrupted after installing this latest Ubuntu release. The issue is appearing most frequently with Lenovo laptops but there are also reports of issues with other laptop vendors as well. This issue appears to stem from the Intel SPI driver in the 17.10's Linux 4.13 kernel corrupting the BIOS for a select number of laptop motherboards. Canonical is aware of this issue and is planning to disable the Intel SPI drivers in their kernel builds. Canonical's hardware enablement team has already verified this works around the problem, but doesn't provide any benefit if your BIOS is already corrupted.

An anonymous reader shares a Bloomberg report: Apple's iPhone and iPad introduced a novel way of interacting with computers: via easy-to-use applications, accessible in the highly curated App Store. The same approach hasn't worked nearly as well on Apple's desktops and laptops. The Mac App Store is a ghost town of limited selection and rarely updated programs. Now Apple plans to change that by giving people a way to use a single set of apps that work equally well across its family of devices: iPhones, iPads and Macs. Starting as early as next year, software developers will be able to design a single application that works with a touchscreen or mouse and trackpad depending on whether it's running on the iPhone and iPad operating system or on Mac hardware, according to people familiar with the matter. Developers currently must design two different apps -- one for iOS, the operating system of Apple's mobile devices, and one for macOS, the system that runs Macs. With a single app for all machines, Mac, iPad and iPhone users will get new features and updates at the same time.

An anonymous Slashdot reader is asking whether or not there are any alternatives to Android or iOS smartphones: Like most of us, I've owned a few smartphones over time, ranging from a Nokia E71 to a Samsung Android phone and now, an Apple iPhone. It is close to phone upgrade time, and I've been reviewing the features that I use on my phone. When I think honestly about it, the only features I really need are:

1. Phone calls (loads of conference calls, for which I use a wired headset with a microphone)
2. SMS Messaging (unlimited on my plan)
3. Navigation (very important, and is probably the most-used app on my phone)
4. Occasional internet browsing

All of this could be done by the Nokia E71, when Nokia Maps was a thing. If I want to move away from Apple, Google and the like, do I have any options now? Are there any trustable (and by trustable, I mean avoiding unknown Chinese manufacturers) phones in the market today that could do all four and (ideally) have better battery life than one day?

An anonymous reader shares a report: Fintech plus cryptocurrency equals about $7 billion. That's how much the value of LongFin surged to after the microcap's stock rocketed by as much as 2,600 percent since debuting Wednesday. Most of the gains came since Friday, when the company issued a press release saying it bought Ziddu.com, "a blockchain-empowered global micro-lending solutions provider" that transacts only in cryptocurrencies. LongFin joins a growing list of little-known companies that have seen their values soar after simply announcing plans to join the digital currency craze that's pushed the value of bitcoin past $300 billion. The microcap rallies are reminiscent of the height of the dot.com bubble, when virtually any company that put tech in its name found favor on the public markets.

Tesla has issued a new policy called Supercharger Fair Use, which prohibits new commercial drivers from using the red-and-white charging ports. The reason behind this new policy is to help alleviate congestion and improve the experience for others who rely on the Supercharging services. The Verge reports: Tesla says that the stations are intended for drivers who don't have ready options for charging at home or at work, and that when they're not used for this purpose, "it negatively impacts the availability of Supercharging services for others." Thus, the new policy says that for vehicles purchased after December 15th, drivers who plan to use their vehicles as a taxi, for ridesharing, commercial delivery or transportation, governmental purposes, or other commercial ventures won't be permitted to use the free stations. The company tracks usage and driver behavior, and if they find that someone isn't complying with the policy, they might be asked to stop, and simply limit or block one's vehicle from the stations in certain instances. The policy went into effect on Friday, December 15th, 2017. A Tesla spokesperson said that the company does "encourage the use of Teslas for commercial purposes," and that they will work with drivers to find other places to charge their vehicles. The policy carve out an exception, saying that some stations might be excluded, depending on local circumstances.

An anonymous reader quotes a report from Ars Technica: U.S. Senate Minority Leader Chuck Schumer (D-N.Y.) said he will force a vote on a bill that would reinstate the Federal Communications Commission's net neutrality rules. Legislation to reverse the repeal "doesn't need the support of the majority leader," Schumer said during a press conference Friday, according to The Hill. "We can bring it to the floor and force a vote. So, there will be a vote to repeal the rule that the FCC passed." The Federal Communications Commission voted to repeal its own net neutrality rules last week, and the repeal will take effect 60 days after it is published in the Federal Register. But Congress can overturn agency actions by invoking the Congressional Review Act (CRA), as it did earlier this year in order to eliminate consumer broadband privacy protections. A successful CRA vote in this case would invalidate the FCC's net neutrality repeal and prevent the FCC from issuing a similar repeal in the future. This would force the FCC to maintain the rules and the related classification of ISPs as common carriers under Title II of the Communications Act. A CRA vote lets Congress "undo regulations with a simple majority," without the possibility of a filibuster, as a Washington Post story said in February. Sen. Ed Markey (D-Mass.) announced a plan to file the CRA resolution last week. "It's in our power to do that and that's the beauty of the CRA rule," Schumer said. "Sometimes we don't like them, when they used it to repeal some of the pro-environmental regulations, but now we can use the CRA to our benefit, and we intend to."

A Maine alternative newsweekly just interviewed self-taught rocket scientist "Mad" Mike Hughes, who still believes that the earth is a flat, Frisbee-shaped disc. ("Think about this. Australia -- which is supposedly on the other side of the planet -- is upside down yet they're holding the waters in the ocean. Now how is that happening?") And Mike's got a new way to prove it after his aborted launch attempt in November. An anonymous reader writes: "One thing I want to clarify is that this rocket was never supposed to prove that the Earth is flat," Hughes tells an interviewer. "I was never going to go high enough to do that." But he will prove it's flat -- with an even riskier stunt. "I have a plan to go 62 miles up to the edge of space. It's going to cost $1.8 million and that could happen within 10 months."

"I'm going to have a balloon built at about $250,000 with $100,000 worth of hydrogen in it. It will lift me up about 20 miles... If I'm unconscious, they can use the controls to bring the balloon back." But if he's still conscious? "Then I'll fire a rocket through the balloon that will pull me up by my shoulders through a truss for 42 miles at 1.5 g's."

It's an awesome plan "if I don't burn up coming back through the atmosphere."
The interviewer asks Hughes a reasonable question. "Wouldn't it be cheaper and less deadly to just try to drill through the Earth to the other side to prove your point?"

"You can't," Hughes answers. "That's another fallacy. The deepest hole ever drilled is seven-and-a-half miles and it was done in Russia. It took 12 years. You cannot drill through this planet. It dulls every drill bit. All the stuff that you learned in school -- that the core is molten nickel -- it's all lies. No one knows what's in the center of the Earth or how deep it is. I'm no expert at anything, but I know that's a fact."
