Using Google’s new Public Data Explorer tool, Ola Rosling demonstrates the effectiveness of visualizing datasets. Looking toward the next political election, Rosling hopes voters will use the tool to answer questions like: How was the money spent? Where are the biggest problems?


Ola Rosling of Google Public Data gives a presentation titled, “Google Public Data Explorer” at the Berkeley Graduate School of Journalism. This program was recorded on April 18, 2010.

Ola Rosling co-founded the Gapminder Foundation and led the development of Trendalyzer, a software that converts time series statistics into animated, interactive and comprehensible graphics. The aim of his work is to promote a fact-based world view through increased use and understanding of freely accessible public data.

In March 2007, Google acquired the Trendalyzer software, where Rosling and his team are now scaling up their tools and making them freely available for any individual or organization to use for analyzing and visualizing data.

Google Privacy Policy

We’re getting rid of over 60 different privacy policies across Google and replacing them with one that’s a lot shorter and easier to read. Our new policy covers multiple products and features, reflecting our desire to create one beautifully simple and intuitive experience across Google.
We believe this stuff matters, so please take a few minutes to read our updated Privacy Policy and Terms of Service at These changes will take effect on March 1, 2012.
Got questions?
We’ve got answers.

States Move on Privacy Law

Over two dozen privacy laws have passed this year in more than 10 states, in places as different as Oklahoma and California.
For Internet companies, the patchwork of rules across the country means keeping a close eye on evolving laws to avoid overstepping.

Ajax (also AJAX; /ˈæks/; an acronym for Asynchronous JavaScript and XML)[1] is a group of interrelated web development techniques used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously (in the background) without interfering with the display and behavior of the existing page. Data can be retrieved using the XMLHttpRequest object. Despite the name, the use of XML is not required (JSON is often used instead), and the requests do not need to be asynchronous.[2]

Ajax is not a single technology, but a group of technologies. HTML and CSS can be used in combination to mark up and style information. The DOM is accessed with JavaScript to dynamically display, and allow the user to interact with, the information presented. JavaScript and the XMLHttpRequest object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads.

The Document Object Model (DOM) is a cross-platform and language-independent convention for representing and interacting with objects in HTML, XHTML and XML documents.[1] Objects in the DOM tree may be addressed and manipulated by using methods on the objects. The public interface of a DOM is specified in its application programming interface (API). The history of the Document Object Model is intertwined with the history of the “browser wars” of the late 1990s between Netscape Navigator and Microsoft Internet Explorer, as well as with that of JavaScript and JScript, the first scripting languages to be widely implemented in the layout engines of web browsers.

Dojo or jQuery, quick answer

  • JQuery if you are new to javascript/web programming and only want to jazz up your pages a little. Also, if your project is only a few months and/or only a few hundred lines, pick JQuery. It will get you there faster.
  • Dojo if you have a large project and can spend time on a very steep learning curve and want to be able to create and re-use widgets, data connections and whatnot.

This answer do not take into account the “fun factor”. If your aim is to have fun JQuery will give you a quick fix but Dojo will be more rewarding in the long run.

Google Nexus

Google Nexus is a line of mobile devices using the Android operating system produced by Google in conjunction with an original equipment manufacturer (OEM) partner. Devices in the Nexus series[1] do not have manufacturer or wireless carrier modifications to Android (such as custom graphical user interfaces), and have an unlockable bootloader[2] to allow further development and end-user modification.[3] Nexus devices are the first Android devices to receive updates to the operating system.[4][5][6] The Galaxy Nexus is one of the few smartphones recommended by the Android Open Source Project for Android software development.[7] As of November 2012[update], the latest devices in the series are the Nexus 4 phone by Google and LG, and the Nexus 7 and Nexus 10 tablet computers by Google with Asus and Samsung respectively.

Search Engine Optimization (SEO)

Internet es la calle más transitada del mundo, pero el trafico en cada pagina depende principalmente del posicionamiento en los buscadores como Google. Al arte de colocarse en los primeros lugares de los listados se le conoce como Search Engine Optimization (SEO).

Google mantiene como secreto la mecánica de asignación de lugares, que además cambia de manera continúa. Es un proceso bastante errático, y los que logran colocarse en la primera pagina para la lista de búsqueda de un conjunto de palabras, tenderán a mantenerse ahí hagan lo que hagan, tengan el contenido que tengan, siempre y cuando Google no los vete, por razones también erráticas y misteriosas. Es decir, el SEO es un deporte extremo.

How to track your Blogger statistics with Google:

  1. Go to Google Analytics to sign up or log in.
  2. When logged in, choose to create a new account and follow the steps.
  3. When you get to “Add Tracking“, open up a new window and log in to your Blogger account.
  4. Go to your blog’s settings and choose “Template” and then “Page Elements“
  5. Have a look at the footer (it has to be the footer!) of the design and choose to “Add a Page Element“.
  6. Find the “HTML/JavaScript” element and then “Add to blog“.
  7. Don’t write anything in the title column.
  8. Copy and paste the code from Google Analytics in the content box and “Save changes”.
  9. Then continue the steps on Google Analytics and you’re done!

Or if you are familiar with coding:

  1. From dashboard – Settings – Template – Edit HTML
  2. Scroll down to the very bottom in the box and locate the tag.
  3. Copy and past the Google code right BEFORE the tag and then save.
  4. To check your stats you just have to click “View Reports”.
  5. If it says “Tracking Unknown” in the status column, you have done something wrong.

Also, you might want to get your blog Google verified (link to tutorial for Blogger) so your blog gets crawled so your chances to show up on search results increases. Here is a tutorial for you users.
