This appeared on Doug Johnson's Blue Skunk Blog on December 1, 2010.In response to a blog post last week, Shannon Miller, Library Media Specialist in Van Meter, Iowa, sent me a personal e-mail. She has graciously allowed me to use the e-mail as a guest blog post...I just wanted to tell you how much I enjoyed your post Dear Students, Please Lead a Thoughtful Revolution. These few lines are just awesome and so RIGHT ON.....If you want to see this kind of revolution that will use technology to help make your schools more effective and meaningful to you - not just the same old, same old with a few bells and whistles - you will need to be the ones who lead the revolution.Technology alone won't create change. I am less and less convinced that adults will be able to fundamentally change how school is done.I think it will be up to you...

What’s the harm in essentially ignoring that privacy policy? While the majority of the time it’s harmless, there are some ne’er-do-wells that may gather your personal information and sell it to marketers, advertisers, or spammers. While terrible, it’s not unheard of.

According to a recent report, there’s a big reason users don’t read privacy policies: they’re too damn long. Of the top 1,000 websites, the longest privacy policy takes about 45 minutes to read…the average takes 10 minutes. About 72% of these websites allow users to opt out of being tracked. However, about 40% make you make navigate to a different (sometimes hard-to-find) section of the website to opt out.

Google has tools like the Google Dashboard, the Ads Preferences Manager and encrypted search if you’re looking for some of the more popular ways to manage your Google interactions. Most recently, Google launched an extension for Chrome called Keep My Opt-Outs, which allows you to opt out permanently from ad tracking cookies. And pretty soon Chrome will be extending the availability of 2-step verification, an advanced account security solution that is now helping protect more than 1,000 new accounts a day from common problems like phishing and password compromise. Right now it’s available to Google Apps Accounts and should available to the general public in a few weeks.

J. M. Bermúdez de Castro, experto en evolución humana, en su libro La evolución del talento. Cómo nuestros orígenes determinan nuestro presente (Debate, 2010), explica que enormes cambios climáticos en África provocaron cambios en los primates de esa zona, uno de ellos en la mano. Mientras «los chimpancés tienen dedos largos y curvados y un pulgar corto, cuyo conjunto constituye una pinza de presión que les permite agarrarse con facilidad a las ramas de los árboles», a partir del Homo habilis, la mano del género Homo fue convirtiéndose en una pinza de precisión, con dedos más cortos que los del chimpancé, exceptuando el pulgar, no solo más largo sino asimismo fácilmente asociable con los demás dedos y especialmente con el índice. «La evolución de la mano de los homininos, favorecida por su forma de locomoción bípeda, ha sido determinante en la evolución humana. Su pinza de precisión entre los dedos índice y pulgar, que se ha ido perfeccionando con el paso del tiempo, permite la fabricación y manipulación de objetos a modo de herramientas, inicialmente de piedra» y causaron cambios tecnológicos que, a su vez, transformaban el cerebro y por tanto la inteligencia de sus usuarios. Nuestros bípedos retoños humanos nacen hoy
