The Cassiopeia Project: Free Science Education Online by Maria Popova What a mysterious retired physicist has to do with the future of learning. In 2008, The Cassiopeia Project began quietly publishing high-definition videos exploring in an intelligent yet digestible manner nearly every corner of the science spectrum, and releasing them online for free. We believe that if you can visualize it, then understanding it is not far behind.” The project, operating under the slogan “No science teacher left behind,” is funded by an adamantly anonymous retired scientist who, after weighing the benefits of helping academic institutions versus helping teachers, he chose the latter and made it his mission to champion science literacy in the US. All the content is open-source and educators are encouraged to edit, remix and otherwise customize the footage. Sadly, the effort appears to be in stagnation since 2009, but we sincerely hope to see it resurface with more fantastic content. via MeFi Share on Tumblr
64 Things Every Geek Should Know - laptoplogic.com The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field. A geek is one who isn’t satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject. A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question. 1.

Virtual Schools Booming As States Mull Warnings DENVER -- More schoolchildren than ever are taking their classes online, using technology to avoid long commutes to school, add courses they wouldn't otherwise be able to take – and save their school districts money. But as states pour money into virtual classrooms, with an estimated 200,000 virtual K-12 students in 40 states from Washington to Wisconsin, educators are raising questions about online learning. States are taking halting steps to increase oversight, but regulation isn't moving nearly as fast as the virtual school boom. The online school debate pits traditional education backers, often teachers' unions, against lawmakers tempted by the promise of cheaper online schools and school-choice advocates who believe private companies will apply cutting-edge technology to education. Is online education as good as face-to-face teaching? Virtual education companies tout a 2009 research review conducted for the U.S. Still, virtual schooling at the K-12 level is booming. Online:

In 2011: How the Internet Revolutionized Education As connection speeds increase and the ubiquity of the Web pervades, free education has never been so accessible. An Internet connection gives lifelong learners the tools to become autodidacts, eschewing exorbitant tuition and joining the ranks of other self-taught great thinkers in history such as Albert Einstein, Alexander Graham Bell, Paul Allen and Ernest Hemingway. We can be learning all the time now, whenever we want, and wherever we want. And because of that, we’re seeing explosive growth in online education. Insider How the Internet is Revolutionizing Education This was our seminal piece on online education, which includes interviews with UC Berkeley professors and CEOs and Founders of today’s most disruptive education startups. Stay in or drop out? There’s a lot of debate right now about whether or not paying for a degree is worth it, a particular problem facing entrepreneurs.

Топики / Избранное / Хабрацентр им. marchevsky Недавно я прочитал о том, что Гэйб Ньюэлл всерьёз настроен на то, чтобы перенести хорошие и качественные игры в Linux. Как он считает, это именно то, чего не хватает, и что на данный момент ограничивает развитие платформы. Безусловно, он прав. Тем не менее, лично для меня есть и другая область, которая мне даже намного важнее, чем игры — это музыка. На картинке — рабочее место Niels Ott, на компьютере запущен Ardour. Моя жена тоже музыкант, и когда она увидела, какие секвенсоры и синтезаторы есть в Linux — она даже не стала пытаться в них разобраться, просто вернувшись к своим Cubase и Reason. Я же, пользуясь Linux уже около 10 лет, не могу так просто отказаться от того, чтобы хотя бы пробовать имеющиеся программы.
4 Reasons Your Brain Loves to Learn Online Are we offloading our brains onto the web? Are programs better than teachers at knowing what we know? Do virtual badges motivate more than grades? We’ve analyzed here four different special powers of online teaching that make brains very happy. 1) Memory: This is your brain on-line. According to Columbia neuroscientist Betsy Sparrow and her team, “We are becoming symbiotic with our computer tools”. Dr. So is offloading our brain making us dumber? “Accessibility [of information] changes the relative importance of certain topics in much the same ways that a calculator changes the relative importance of some things.” Kuntz, who’s V.P. of research at the fast growing adaptive learning company, explained that fields of knowledge that were off-loaded simply left room for cogitation on other topics. “Long division, for example, is a process that, in my opinion, is more or less irrelevant, you never have to work through a problem in that way.” He measured responses to curvey lines, like this one:
Stop Looking For a Job, Start Looking for an Opportunity | Under30CEO A lot of jobs that once were, aren’t coming back. Ever.

Khan Academy Triples Unique Users To 3.5 Million Today at The Web 2.0 Summit in San Francisco, Founder of Khan Academy, Salman Khan, took the stage to share a few quick stats on the growth of his online video education platform. For those unfamiliar, Khan Academy is, as John Batelle noted this afternoon, one of Bill Gates’ favorite educators. It also happens to be one of mine, but I thought you’d probably resonate a bit more with Bill Gates. But Khan Academy is the institution of Salman Khan, who brought the idea of educating young people, self-starters, people who learn at their own pace — online. While Khan is a not-for-profit organization, the Academy has received donations from The Gates Foundation and also won Google’s “Project 10^100″. It looks like all the publicity and traction Khan Academy has been getting of late is really starting to pay off, which is great to see.
Введение PowerShell и администрирование будущего Долгое время визитной карточкой Windows служил графический интерфейс, а желающим поработать в консоли приходилось довольствоваться весьма урезанным функционально cmd.exe. Появление PowerShell с гибким языком сценариев изменило ситуацию к лучшему. Используя его возможности, можно легко выполнить практически любую задачу, возникающую перед администратором. Зачем админу PowerShell? Если настройку при помощи графических утилит можно назвать наглядной, то консоль вырывается вперед, когда говорят об автоматизации задач и обработке большого количества данных. Ранее админу, чтобы упростить себе работу, необходимо было использовать командные BAT-файлы, VBScript, JavaScript, Windows Script Host, Perl и прочие инструменты, позволяющие управлять системной информацией. Сейчас PowerShell встроен в Win2k8/R2/Se7en и доступен как опциональный компонент для WinXPSP2/2k3/Vista. Начинаем исследование PS> Get-Process | Sort CPU -Descending | Select -First 10 Все просто!

The Stanford Education Experiment Could Change Higher Learning Forever | Wired Science Sebastian Thrun and Peter Norvig in the basement of Thrun's guesthouse, where they record class videos.Photo: Sam Comen Stanford doesn’t want me. I can say that because it’s a documented fact: I was once denied admission in writing. Last fall, the university in the heart of Silicon Valley did something it had never done before: It opened up three classes, including CS221, to anyone with a web connection. People around the world have gone crazy for this opportunity. Aside from computer-programming AI-heads, my classmates range from junior-high school students and humanities majors to middle-aged middle school science teachers and seventysomething retirees. It’s not until the second week of class that I notice a small disclaimer on the AI course website: Prerequisites: A solid understanding of probability and linear algebra will be required. Solid understanding? Apply this rule to a computational problem and you can make efficient predictions based on otherwise unreliable data.

The Wrath Against Khan: Why Some Educators Are Questioning Khan Academy An Explainer Post There's an article in this month's Wired Magazine about Khan Academy. The headline speaks volumes -- "How Khan Academy Is Changing the Rules of Education" -- as do the responses I've seen to the article. As usual, there's plenty of praise for Sal Khan and his one-man-educational-video-making machine. But there's also push-back from some quarters, particularly from educators who are highly skeptical of what Khan Academy delivers and what it stands for. That dichotomy says it all, right? Technology Replacing Teachers If one person can create 2400 educational videos and these videos can in turn be viewed by anyone with an Internet connection then why do we need teachers? While "technology will replace teachers" seems like a silly argument to make, one need only look at the state of most school budgets and know that something's got to give. The Bill Gates Connection "Retain qualified people." What does all of this have to do with Sal Khan? Old Wine, New Bottles, Bad Pedagogy
Все по полочкам Немалая часть задач, связанных с обслуживанием локальных вычислительных сетей, представляет собой выполнение рутинных операций, ручная реализация которых может потребовать значительного времени. Вероятно, решения, позволяющие автоматизировать выполнение административных задач, которые могли бы повысить производительность, возникли почти сразу же с появлением профессии системного администратора. Наиболее распространенным средством «экономии времени и избавления от головной боли» стала запись и последовательное пакетное исполнение необходимых операций - исполнение сценариев или скриптов в интерпретаторе команд операционной системы. Попытки улучшить состояние дел в области управления и администрирования Windows с помощью командного интерфейса привели не к адаптации чужеродного для системы языка сценариев или созданию супер-утилиты, работающей в DOS, а к появлению PowerShell – новой командной оболочки. Знакомство В состав PowerShell включена довольно обширная справочная система. Параметры
