There’s no question Clayton Christensen, who developed the theory of disruption, is Silicon Valley’s favorite business school professor. For me, diving deep into his thinking in a corporate innovation class was a breath of fresh air from management theory that explained all of corporate America but for its most successful company – Apple. It’s Apple, though, that has long been Christensen’s bugaboo: In a January 2006 interview with Businessweek, Christensen predicted the imminent demise of the iPod: Q: Can Apple keep it up? Christensen: I don’t think so. It is this concern that is the primary bear narrative about Apple. Two Theories of Disruption That final excerpt is useful in that it highlights the fact Christensen has two theories of disruption.2 This remains an incredibly elegant and powerful theory, and I fully subscribe to it. It is Christensen’s second theory of disruption – low-end disruption – that I believe is flawed. The Flaw in the Theory Consumers Aren’t Rational This is it.
What Clayton Christensen Got Wrong in his Theory of Low-End Disruption
Part of my conversion stems from an abiding distaste for corporate and government control-freakery. If we believe in liberty, we have to realize that we take risks to be more free. If we believe in competition, we sometimes have to intervene as a society to ensure that it’s fair. One way we try to ensure fair competition is enforcement of laws designed to promote it, notably antitrust rules that seek to prevent dominant companies from abusing their dominance. A classic example emerged in the 1990s: Microsoft, a company that had outsmarted and/or outsleazed IBM and everyone else in its rise to pure dominance in the operating system and office “productivity” software markets. Microsoft’s software wasn’t the best in many cases, but it was more than good enough — and the company’s business tactics ranged from brilliant to ugly, often both at the same time. I made a personal “declaration of independence” from the software company, at least to the extent possible at the time.

Phone calls. Millennials are allergic to them. I have this conversation Sofa King often that I’m sure each reader who has met me will think I’m talking specifically about you. I’m not. Well, I am. But not only you. Email is efficient. Phone calls are effective. Of course in-person is best for true relationship development but that’s not always practical. A very common experience … One person emails some thoughts. I’ve written before about the dehumanization of other people and their feeling with written words – exacerbated by anonymous apps. So my appeal to those in confrontational situations is to pick up the phone – even if it makes you uncomfortable. Pick up the phone. I’ve written about the art of the phone call before but thought I’d include a primer below for those with less experience. 1. 2. Two things to watch for: 1) if you’re trying banter to build rapport but not “feeling it” then quickly shift to business. It’s an art. 3. 4. 5. 6. 7. 8. 9.

Genomic Loopholes and Other Weapons - Issue 6: Secret Codes
Back in 2000, before MRSA—Methicillin-resistant Staphylococcus aureus—had become a household word, Nobel Laureate Joshua Lederberg wrote in the journal Science that “the future of humanity and microbes [would] likely unfold as episodes of a suspense thriller that could be titled Our Wits Versus Their Genes.” Thirteen years later, it is “their genes” that seem to be winning out. In the United States alone, roughly 2 million people suffer from drug-resistant infections each year; according to the most recent Centers for Disease Control and Prevention (CDC) report, about 23,000 of them die. While the microbes have cracked almost all of our codes—rapidly evolving around one drug after another—we have yet to fully crack many of theirs. Scientists have a growing understanding of the molecular wizardry by which bacteria develop resistance to antibiotics, but they have yet to circumvent it. Antibiotics are, by far, the greatest weapon we humans have had in this contest.
Ekocycle 3D printer uses recycled plastic bottles as component in filament cartridges
Cubify has announced that it will be selling a $1199 printer later this year called the Ekocycle Cube 3D Printer—it will be using recycled PET plastic bottles as one component in its filament cartridges—a single cartridge will hold the equivalent of three 20oz. bottles, making up 25 percent of its content. Entertainer Will.i.am, chief creative officer for 3DSystems, designer of the printer (in collaboration with Coca-Cola), is serving as a promoter to drum up support for the printer and for the creation of eco-friendly technology in general. In a supporting video he suggests that the path to creating eco-friendly technology products is though making the idea "cool" to consumers, which in theory should create demand for them. "Waste is only waste, if you waste it" he notes dryly. He's also at work creating designs for 25 accessories that can be printed with the cube. Initially, at least, the printer will be able to create objects with just four colors, natural, red, black and white.
It doesn’t really matter what you use to do it – typing is just about the same on all devices. Oh, sure, it’s bigger on some devices and smaller on others, but the letters and the keys are pretty much all in the same spots, and you have to press them all the same to get your message out. We’ve been typing the same way since basically the advent of the typewriter, QWERTY and all. Don’t you think it might be time for some kind of a change? The folks at AirType do, and I have to admit – what they’ve designed is intriguing to say the least. The keyboard works using 2 bluetooth bracelets which connect to an app to learn your typing habits. At this point in AirType’s development there is no mention of how much it will ultimately cost. What do you think? [Image via DudeIWantThat] SOURCE: AirType

Bitcoin mining the hard way: the algorithms, protocols, and bytes
This article explains Bitcoin mining in details, right down to the hex data and network traffic. If you've ever wondered what really happens in Bitcoin mining, you've come to the right place. My previous article, Bitcoins the hard way described how I manually created a Bitcoin transaction and sent it into the system. In this article, I show what happens next: how a transaction gets mined into a block. The purpose of mining Bitcoin mining is often thought of as the way to create new bitcoins. The main problem with a distributed transaction log is how to avoid inconsistencies that could allow someone to spend the same bitcoins twice. Although mining transactions into blocks avoid double-spending, it raises new problems: What stops people from randomly mining blocks? Each mined block references the previous block, forming an unbroken chain back to the first Bitcoin block. As a side-effect, mining adds new bitcoins to the system.

10 Tips for Teachers who Struggle with Technology
With technology moving out of the lab and into the classroom, it’s becoming a challenge for some teachers to infuse their teaching with tech tools such as websites, educational games, simulations, iPads, Chromebooks, GAFE, and other geeky devices that used to be the purview of a select group of nerdy teachers. Now, all teachers are expected to have students work, collaborate, research, and publish online. I’m fine with that because I am that nerd, but if I was expected to integrate art into my classroom, I’d break out in a cold sweat and expect the worst. As the tech coordinator responsible for helping teachers use these tools in their classrooms, I hear too often from experienced, valuable, long-time teachers that they believe the time has come for them to retire, that they just don’t get this new stuff. I also have colleagues who think it takes a special brain to understand tech (the same way students think about math and science)–one they don’t have. Make yourself use it every day
There has been much talk in the media lately about technology in education, the large sums of money involved and the limited impact it has had upon results. The OECD report on the surface of things looked pretty scathing. That's because popular media always looks for the big title to draw readers in. "It calls for new approaches to integrating technology into teaching, because at present technology use is not optimal...What the report is actually saying is that technology is no substitute for good pedagogy... This of course makes absolute sense. For teachers, half the battle with using tech is often the confidence to have a go yourself and to allow your students to have a go too; the other half is then to make that use purposeful, and not just shoe-horned in because you've been told you should use it. For me, a significant part of the problem is actually that people focus upon all of this as being a technology 'thing'. SAMR image by Mark Anderson @ICTEvangelist

2009년 기획 특집 'VGA 쿨러 12종 벤치마크' :: 다나와 DPG
그래픽 카드 쿨러는 컴퓨터 부품 가운데 변화가 없기로 둘째가라면 서러운 분야다. CPU와는 달리 제조사 레벨에서 그래픽 카드 기판, GPU, 쿨러가 모두 정해져서 출고되는 경우가 많기 때문이다. 특히 국내 유통사를 비롯한 몇몇 제조사들은 그래픽 카드 쿨러 제조사와 계약을 맺고 시중에서 판매되는 고성능 쿨러를 OEM으로 탑재하고 출시하기 때문에 그 양상이 두드러진다. 그러나 아무리 좋은 쿨러라도 소모품이다 보니 고장에서 자유로울 수 없는 법이고, 설계가 부실한 제조사 쿨러로는 그래픽 카드의 발열을 버티지 못하는 웃지 못할 황당 사건도 부지기수로 일어나곤 한다. 더욱이 오늘날에는 부쩍 빨리 찾아와 오래가는 고온 다습한 여름철은 과열 양상이 더욱 두드러지다 보니 소비자들의 관심이 높아지는 쿨러업계의 성수기이기도 하다. 2006년산 구닥다리부터 2009년 최신 제품까지 한자리에 모아 놓은 2009년 브레인박스 그래픽 카드 쿨러 벤치마크, 지금부터 시작해보도록 하자. 아, 그전에 본 기사의 제품 배열은 모두 출시 시기를 기준으로 나열되었으니 참고하시기 바란다. 2009년 그래픽 카드 쿨러 벤치마크는 조금 오래 되었더라도 아직 한가닥 한다는 제품들까지 모두 끌어 모으다 보니 제품이 너무 많아져 급수도 나누게 되었다. 수 차례 의견 조율 끝에 정해진 쿨러 구분은 바로 '덩치와 팬'이다. 먼저 살펴볼 제품들은 소형 쿨러들이다. [ 에이팩 ZEROtherm CoolMaxx 1000 ] 신상품 나열의 법칙에 따라 가장 먼저 소개할 제품은 잘만과 함께 우리나라 고성능 쿨러 제조사, 에이팩의 신상품인 "제로썸 CoolMaxx 1000" 이다. 제로썸 CoolMaxx 시리즈는 가장 최근에 출시된 제품이다. 방열핀은 열 방출 효율이 좋은 알루미늄을 사용했다. 제로썸 CoolMaxx 1000의 바닥면 모습이다.

The Huawei MediaPad M3 is like a louder, more affordable Apple iPad Mini 4, that runs Android. The stylish, aluminum-clad tablet bears a striking resemblance to the iPad Mini 4 in design, and its performance is just as powerful, however the Huawei tablet has better speakers and cheaper pricing -- for both Wi-Fi only and LTE models. The Wi-Fi only model will hit the US in December for $299. Sight and sound 8.4-inch screen2,560x1,600-pixel resolution IPS screen359 ppiHarman Kardon speakers Tablets are great for media consumption (aka watching hella amounts of Netflix), so it's no surprise that the very literally named MediaPad M3 is one of the best binge-watch-friendly models around. The speakers are surprisingly loud, crisp and clear; dialogue in movies was always at the forefront and vocals in music sounded appropriately accentuated. Supremely sleek Let's be real: all tablets kind of look the same and how one feels in your hands can many times be the deciding factor. Enlarge Image
