64 Things Every Geek Should Know - 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.

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

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.

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:

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!

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.

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
