    Clayton Christensen, Father of 'Disruptive Innovation,' Dies At 67
    Clayton Christensen, the business scholar who coined the term "disruptive innovation," died of cancer treatment complications on Thursday at age 67. The Verge reports: You may not immediately recognize his name, but the tech industry -- and every resulting industry -- is built on the framework of technology disruption and innovation that Christensen devised. The crux of Christensen's theory is that big, successful companies that neglect potential customers at the lower end of their markets (mainframe computers, in his famous example) are ripe for disruption from smaller, more efficient, more nimble competitors that can do almost as good a job more cheaply (like personal computers). One need look no further than the biggest names in Silicon Valley to find evidence of successful disrupters, from Napster to Amazon to Uber to Airbnb and so on. And scores of notable tech leaders have for years cited Christensen's 1997 book The Innovator's Dilemma as a major influence. It's the only business book on the late Steve Jobs' must-read list; Netflix CEO Reed Hastings read it with his executive team when he was developing the idea for his company; and the late Andy Grove, CEO of Intel, said the book and Christensen's theory were responsible for that company's turnaround. [...] He later refined his thinking on disruption, introducing the concept of "jobs to be done," which stressed the need to focus on customers' needs, and acknowledged that disruption was a great way to start a company, but not a good way to grow a company. "It's not a manual for how to grow or how to predict what customers want. [Jobs to be done] is the second side of the same coin: How can I be sure that competitors won't kill me and how can I be sure customers will want to buy the product? So it's actually a very important compliment to disruption."

    Gravity: We Might Have Been Getting It Wrong This Whole Time
    Motoko Kakubayashi, from the Kavli Institute for the Physics and Mathematics of the Universe, writes via Phys.org: Physicists have been looking for laws that explain both the microscopic world of elementary particles and the macroscopic world of the universe and the Big Bang at its beginning, expecting that such fundamental laws should have symmetry in all circumstances. However, last year, two physicists found a theoretical proof that, at the most fundamental level, nature does not respect symmetry. There are four fundamental forces in the physical world: electromagnetism, strong force, weak force, and gravity. Gravity is the only force still unexplainable at the quantum level. Its effects on big objects, such as planets or stars, are relatively easy to see, but things get complicated when one tries to understand gravity in the small world of elementary particles. To try to understand gravity on the quantum level, Hirosi Ooguri, the director of the Kavli Institute for the Physics and Mathematics of the Universe in Tokyo, and Daniel Harlow, an assistant professor at the Massachusetts Institute of Technology, started with the holographic principle. This principle explains three-dimensional phenomena influenced by gravity on a two-dimensional flat space that is not influenced by gravity. This is not a real representation of our universe, but it is close enough to help researchers study its basic aspects. The pair then showed how quantum error correcting codes, which explain how three-dimensional gravitational phenomena pop out from two dimensions, like holograms, are not compatible with any symmetry; meaning such symmetry cannot be possible in quantum gravity.

    36 Years Ago Today, Steve Jobs Unveiled the First Macintosh
    An anonymous reader quotes a report from MacRumors: On January 24, 1984, former Apple CEO Steve Jobs introduced the first Macintosh at Apple's annual shareholder's meeting in Cupertino, California, debuting the new computer equipped with a 9-inch black and white display, an 8MHz Motorola 68000 processor, 128KB of RAM, a 3.5-inch floppy drive, and a price tag of $2,495. The now iconic machine weighed in at a whopping 17 pounds and was advertised as offering a word processing program, a graphics package, and a mouse. At the time it was introduced, the Macintosh was seen as Apple's last chance to overcome IBM's domination of the personal computer market and remain a major player in the personal computer industry. Despite the high price at the time, which was equivalent to around $6,000 today, the Macintosh sold well, with Apple hitting 70,000 units sold by May 1984. The now iconic "1984" Super Bowl ad that Apple invested in and debuted days before the Macintosh was unveiled may have helped bolster sales.

    GE Fridges Won't Dispense Ice Or Water Unless Your Water Filter 'Authenticates' Via RFID Chip
    JustAnotherOldGuy writes: Count GE in on the "screw your customers" bandwagon. Twitter user @ShaneMorris tweeted: "My fridge has an RFID chip in the water filter, which means the generic water filter I ordered for $19 doesn't work. My fridge will literally not dispense ice, or water. I have to pay General Electric $55 for a water filter from them." Fortunately, there appears to be a way to hack them to work: How to Hack RWPFE Water Filters for Your GE Fridge. Hacks aside, count me out from ever buying another GE product if it includes anti-customer "features" like these. "The difference between RWPF and RPWFE is that the RPWFE has a freaking RFID chip on it," writes Jack Busch from groovyPost. "The fridge reads the RFID chip off your filter, and if your filter is either older than 6 months or not a genuine GE RPWFE filter, it's all 'I'm sorry, Dave, I'm afraid I can't dispense any water for you right now.' Now, to be fair, GE does give you a bypass cartridge that lets you get unfiltered water for free (you didn't throw that thing away, did you?). But come on..." Jack proceeds to explain how you can pop off the filter bypass and "try taping the thing directly into your fridge where it would normally meet up when the filter is install." If you're able to get it in just the right spot, "you're set for life," says Jack. Alternatively, "you can tape it onto the front of an expired RPWFE GE water filter, install it backward, and then keep using it (again, not recommended for too much longer than six months). Or, you can tape it to the corresponding spot on a generic filter and reinstall it."

    Free Software Foundation Suggests Microsoft 'Upcycles' Windows 7 As Open Source
    The Free Software Foundation (FSF) is urging Microsoft to open source Windows 7, which is no longer supported by the company. The Register reports: On the face of it, the logic seems pretty simple. On January 14, Windows 7 reached its end of life as Microsoft turned off the free security update taps with a final fix. "Its life doesn't have to end," cried the foundation. "We call on Microsoft to upcycle it instead." Unfortunately, the FSF couldn't resist a final dig, saying the killing of the OS had brought to an end "its updates as well as its 10 years of poisoning education, invading privacy, and threatening user security." There is a precedent. Ancient MS-DOS and Word code has been opened up, and the Calculator app found in the current Windows 10 now lurks on GitHub. But an entire, relatively recent OS? We can see some problems, not least the licensed components lurking in Windows 7 that would need to be either excised or open-sourced as well. Then there are the bits and pieces that the company would consider valuable secrets (large chunks of Windows 7 linger on in Windows 10 after all.) And then there is the fact that Windows 7 is not actually unsupported. Three more years of updates are available for those who can pay. And with Windows (as well those parts of it licensed to third parties) still accounting for a sizeable chunk of Microsoft's revenues, we can imagine a very functional and highly compatible free version is not really in the company's best fiscal interests. You can read the FSF's "Upcycle Windows 7" petition here.

    Support Grows For Unionizing Video Game Industry, Survey Finds
    An anonymous reader quotes a report from The Hollywood Reporter: Ahead of the Game Developer's Conference (GDC) -- which is dedicated to the art and science of making video games and set to take place March 16-20 at the Moscone Center in San Francisco -- the results of the organization's eighth annual State of Industry report were released Friday. Surveying nearly 4,000 video game developers with the intent of highlighting industry trends and forecasts for the future of gaming, this year's report indicates an increasing interest in the games industry to unionize. This was also a major topic of conversation in 2019, amid reports of gaming professionals working extended overtime hours and tolerating poor working conditions. Among the survey participants, 54 percent said that game industry workers should unionize (a 7 percent increase from last year), 21 percent answered "maybe" and 9 percent said they weren't sure. When the same group was asked whether they thought game industry workers would unionize, only 23 percent said "yes," while 43 percent said "maybe."

    Apple TV Plus Reportedly Has More Subscribers Than Disney Plus
    If a report from The Wall Street Journal is correct, Apple's TV Plus service that launched late last year has 10 million more subscribers than Disney Plus, which launched at a similar time but with access to almost every TV show and movie Disney owns the rights to. For comparison, Apple TV Plus launched with only 11 titles. Fast Company reports: According to the Wall Street Journal, an Ampere Analysis study found that Apple's fledgling Apple TV Plus service garnered an astounding 33.6 million subscribers in the U.S. in Q4 2019. That puts it as the third-most-popular streaming service in America. Here are the top five streaming video services according to the report: 1.) Netflix -- 61.3 million U.S. subscribers; 2.) Amazon Prime Video -- 42.2 million U.S. subscribers; 3.) Apple TV Plus -- 33.6 million U.S. subscribers; 4.) Hulu -- 31.8 million U.S. subscribers; 5.) Disney Plus -- 23.2 million U.S. subscribers. To be sure, Apple TV Plus is the video streaming service with the lowest monthly cost at just $4.99, but with only 11 series or movies available at launch in Q4 2019, how on earth did it leapfrog Disney Plus with its catalog of Marvel, Star Wars, and Pixar offerings (not to mention Baby Yoda)? The answer probably lies in the fact that Apple began giving away free subscriptions to its Apple TV Plus service to anyone who bought an iPhone, iPad, Mac, or Apple TV from mid-September onwards. Given that Apple sells tens of millions of those devices a month, it's no wonder Apple TV Plus has accumulated so many subscribers already. However, the real test for Apple will be how many of those subscribers stay on once their year-long free subscription of Apple TV Plus comes to an end.

    YouTube Moderators Are Being Forced To Sign PTSD Forms
    According to The Verge, content moderators for YouTube are being ordered to sign a document acknowledging that performing the job can cause post-traumatic stress disorder (PTSD). From the report: "I understand the content I will be reviewing may be disturbing," reads the document, which is titled "Acknowledgement" and was distributed to employees using DocuSign. "It is possible that reviewing such content may impact my mental health, and it could even lead to Post Traumatic Stress Disorder (PTSD). I will take full advantage of the weCare program and seek additional mental health services if needed. I will tell my supervisor/or my HR People Adviser if I believe that the work is negatively affecting my mental health." The PTSD statement comes at the end of the two-page acknowledgment form, and it is surrounded by a thick black border to signify its importance. It may be the most explicit acknowledgment yet from a content moderation company that the job now being done by tens of thousands of people around the world can come with severe mental health consequences. "The wellbeing of our people is a top priority," an Accenture spokeswoman said in an email. "We regularly update the information we give our people to ensure that they have a clear understanding of the work they do -- and of the industry-leading wellness program and comprehensive support services we provide."

    'There's Nothing Wrong With My No-Email Policy'
    Julian Lewis MP responds to criticism over his refusal to use email for constituency correspondence, and says letters, phone calls and surgery appointments are "perfectly adequate." He writes: There is nothing "mysterious" about the fact that I do not use email for constituency correspondence: it is openly stated on the homepage of my -- very extensive -- website, and has been remarked upon in the press from time to time previously. Nor am I in the least "uncontactable," as Bridget Craig (Letters, January 23) knows perfectly well, having corresponded with me by letter without difficulty. Letters, phone calls, and, where appropriate, surgery appointments are perfectly adequate for people who genuinely need my help, as the many letters of thanks quoted on my website fully confirm. Only mass, manipulative campaigners and obsessive individuals find this a problem -- and so they should! Much of the organized abuse which has caused many MPs to "burn out" and withdraw from public life results from their opening up themselves and their long-suffering staff to interactive online communications by email and social media. Indeed several have confided that they wish they had adopted my unshakable policy right at the outset.

    EPA Reasoning For Gutting Fuel-Economy Rule Doesn't Hold Up, Senator Finds
    An anonymous reader quotes a report from Ars Technica: The Trump administration has for several years been working to weaken federal vehicle fuel-efficiency standards. To justify these changes, regulatory agencies argued that more stringent standards would both cost consumers more and reduce road safety. A draft version of the new final rule, however, seems to directly contradict those lines of reasoning. The draft of the Safer Affordable Fuel-Efficient (SAFE) Vehicles rule has not been released publicly, but Sen. Thomas Carper (D-Del.) has seen it. In a letter (PDF) to the White House, Carper says not only is the rule "replete with numerous questionable legal, procedural, and technical assertions," as well as "apparent typographical and other errors," but it also completely fails to provide the safety or economic benefits initially claimed. "Remarkably, the costs of the Trump administration's draft final rule exceed its benefits to Americans" relative to the current standards. The senator writes: "While the draft final rule finds that the per vehicle purchase price would be reduced relative to the Obama rules by $977 (EPA greenhouse gas standards)/$1,083 (DOT's fuel economy standards), the draft final rule also projects that the increased gasoline consumers would have to use to operate the less fuel-efficient vehicles would ad $1,461 (EPA greenhouse gas standards)/$1,423 (DOT fuel economy standards) to these costs. Adding hundreds of dollars to the cost of each vehicle would seem to be the opposite of the more "affordable" vehicles the SAFE rule promised." Further, Carper notes, the estimate of lives potentially saved over a nearly 50-year time period by upgrading to new cars does not take into account the lives potentially lost to illness and disease attributable to increased pollution from less efficient cars. And of course, Carper notes, lower fuel-economy standards that result in consumers buying and using more gas, means burning more fossil fuels at a time when we should be doing the opposite. "My office's review of the draft final rule indicates that it utterly fails to provide any demonstrable safety, environmental, or economic benefit to consumers or the country," Carper concludes. "It should be abandoned. At a minimum, I seek your commitment that you will not allow the finalization of this extreme and unlawful environmental rollback in any form that even remotely resembles" the current draft.

    Spot the Robot Dog Trots Into the Big, Bad World
    Boston Dynamics' creation is starting to sniff out its role in the workforce: as a helpful canine that still sometimes needs you to hold its paw. From a report: This autumn, after years of dropping view-amassing videos of Spot the robot dog fending off stick-wielding humans and opening doors for its pals, Boston Dynamics finally announced that the machine was hitting the market -- for a select few early adopters, at least. BD's people would be the first to tell you that they don't fully know what the hypnotically agile robot will be best at. Things like patrolling job sites, sure. But Spot is so different than robots that have come before it that company execs are, in part, relying on customers to demonstrate how the machine might actually be useful. After a few months on the job, Spot is beginning to show how it'll fit in the workforce. BD's researchers have kept close tabs on the 75 or so Spots now working at places like construction companies and mining outfits. (Oh, and one's with MythBuster Adam Savage for the next year.) They're seeing hints of a new kind of cooperation between humans and machines, and even machines and other machines. Starting today, you can even customize Spot to your liking -- the software development kit is now publicly available on GitHub. The robot is not included, though.

    New York State Wants To Ban Government Agencies From Paying Ransomware Demands
    Two New York state senators proposed two bills last week to ban local municipalities and other government entities from using taxpayer money for paying ransomware demands. From a report: The first bill (S7246) was proposed by Republican NY Senator Phil Boyle on January 14. The second bill (S7289) was introduced by Democrat NY Senator David Carlucci, two days later, on January 16. Both bills are under discussion in committee, and is unclear which will move forward to a vote on the Senate floor. Both S7246 and S7289 have similar texts. The only difference between the two is that S7246 also proposes the creation of a state fund to help local municipalities improve their cyber-security posture. "The Cyber Security Enhancement Fund that will make available grants and financial assistance to villages, towns, and cities with a population of one million or less for the purpose of upgrading the cyber security of their local government," the text of the S746 bill reads.

    China's Battle With the Wuhan Coronavirus is Shackled by a Toxic Relationship With Information
    An anonymous reader shares a report: People are panicking. When a new disease is discovered, it's undeniably hard to identify and inform the public about it quickly. Yet China is making the problem harder to solve, even though it should have learned from the SARS outbreak in 2003, when the government admitted to underreporting cases in the initial stages. Nearly 800 people died in that epidemic, which saw desperate people emptying shops for Chinese herbal medicines and vinegar that would turn out to be ineffective. That frenzy was driven by the lack of accurate information and rumors because of a vacuum in top-down communication. The idea of wei wen, or maintaining stability in China's political system made "conceal as many as possible and keep it at the local level" a natural immediate response to a crisis like this. That approach to information might work on other kinds of issues, but not when it comes to a potential epidemic. Trying to control information in that case becomes a kind of shackle in the face of something that can progress and change swiftly beyond one's control. Of course, there is one thing that's different than 17 years ago: WeChat. A tool connecting more than a billion users in China should be one the government can use to help keep the public up-to-date, and to debunk false information. Yet it too has become a hotbed for both rumors and information suppression amid China's broader regime of online censorship honed over the past decade. Already, a focus of social media discussion about the current virus crisis has been on how hard it's been to get correct information, and whether officials were slow to respond in the early stages, at least in Wuhan. While some international public health experts have commended China's information sharing as superior to 2003 in the face of a quickly evolving situation, others have expressed doubt that the country is being as transparent as it should be.

    Tetris Returns To Android and iOS After EA's Version Shuts Down
    Just days after EA announced that its mobile Tetris games will shut down on April 21st, new Tetris developer N3twork released an officially licensed version of the popular puzzle game for both Android and iOS. From a report: The new N3twork app isn't the 100-player Tetris Royale app that the developer is also working on; rather, it's an extremely basic mobile Tetris game. "We're launching Tetris with a traditional solo gameplay mode, but we want fans to know that we've got so much more in store for them, and this is just the foundation of an incredible Tetris app experience we're building at N3twork," commented CEO Neil Young. Unlike EA's old app, there's a single mode (for classic Tetris) and a handful of alternative skins. There are also ads, although a single-time $4.99 purchase will remove those. It's not exactly a groundbreaking iteration of the series, but if you just want to play some Tetris on your commute, it'll get the job done.

    Air-Traffic Control Is in the Midst of a Major Change
    Shift from radar to GPS should make tracking faster and more accurate, allowing more planes in the air. From a report: Since World War II, air-traffic controllers have used radar to keep track of aircraft. But as of Jan. 1, most planes and helicopters flying in the U.S. must be equipped with transponders that allow their movements to be traced with GPS coordinates. The deadline caused a flurry of upgrades last year as operators who hadn't yet complied with the mandate rushed to equip their aircraft in time. Now, more than 100,000 commercial and general aviation aircraft have the transponders, according to the Federal Aviation Administration, including nearly all commercial aircraft and an estimated 60% of general aviation aircraft that need it. "If you're flying an antique plane in the middle of Ohio, you don't have to have it," said John Zimmerman, vice president of Sporty's Pilot Shop, an Ohio retailer and flight school. The U.S. controls 29.4 million square miles of airspace, including all of the U.S., large portions of the Atlantic and Pacific oceans and the Gulf of Mexico. The FAA mandate primarily applies to Class A airspace, which is 18,000 feet or more above sea level; Class B airspace, the areas surrounding the nation's busiest airports; Class C airspace, the areas around smaller regional airports; and above 10,000 feet in Class E, the most common airspace. LaGuardia Airport in New York is Class B. Richmond International Airport in Virginia is Class C.

    인생에서, 100% 순이익을 보장하는건 없다. 1%의 지식을 나눔으로써, 가끔씩 손해볼 필요도 있다.
    그대가 가진 1%의 지식만이라도 공공을 위해 포스팅하라. 손해본다는 생각이 앞선다면 그대의 인생은 힘들어질것이다.
    자신이 가진 지식의 1%도 투자하지 않고, 오로지 자신의 이익만 탐하는자와는 동지가 되지마라.
    만나서 대화하면 모두 좋은 사람들이지만, 유독 인터넷에서만 자신을 밝히지 않고, 좀비로 서식하는 사람들이 많다.
    부지불식간[不知不識間], 좀비(하류) 인생이 될지도 모르니, 항상 자신을 경계하도록 하라.
