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 Glass

LOS ANGELES (AP) — An early adopter of Google’s Internet-connected eyeglasses plans to fight a citation for wearing the device while driving in San Diego, saying the technology makes navigation easier than smartphones and GPS devices.

Driver Cecilia Abadie was pulled over for speeding Tuesday evening, when a California Highway Patrol officer noticed she was wearing Google Glass and tacked on a citation usually given to drivers who may be distracted by a video or TV screen.

A challenge to what may be a first-of-its-kind citation could force authorities to re-examine laws and consider how best to regulate evolving gadgetry that will one day become mainstream.

The lightweight eyeglasses, which are not yet widely available to the public, feature a hidden computer and a thumbnail-size transparent display screen above the right eye. Users can scan maps for directions — as well as receive web search results, read email and engage in video chats — without reaching for a phone.

About 10,000 have been distributed so far in the United States to “explorers” like Abadie, and this week Google announced another 30,000 would be available for $1,500 apiece. Abadie, a software developer, got what she describes as the life-changing technology in May.

In an interview Thursday, she said she was not using her Google Glass when she was pulled over for allegedly going about 80 mph in a 65 mph zone on the drive home to Temecula after visiting a friend.

“The Glass was on, but I wasn’t actively using it” to conserve the battery, she said. The device becomes inactive if it’s not asked to perform a task.

Abadie expressed surprise that wearing the glasses while driving would be illegal and said she’s “pretty sure” she will fight the ticket. First, she said, she needs to seek legal counsel. In the flurry of online commentary her traffic stop has generated, several people saying they are attorneys offered their services.

“The law is not clear, the laws are very outdated,” Abadie said, suggesting that navigating with the device could be less distracting than with a GPS unit or phone because drivers don’t have to glance down.

“Maybe Glass is more a solution to the cellphone problem than a problem,” she said.

It’s unclear whether a citation for Google Glass has been issued before. The CHP said it is not sure whether an officer within its own ranks has written one, and an agency spokesman pointed out hundreds of law enforcement agencies in California alone can write traffic tickets.

What is clear, CHP Officer Marc Hale said, is that drivers should not use Google Glass.

“Anything that takes your attention away from the motoring public in front of you is a distraction,” Hale said.

Though Google Glass users can continue looking ahead, by glancing at the screen they still divert attention from the roadway and that can make the headgear dangerous, according to David Strayer, director of the University of Utah’s Center for the Prevention of Distracted Driving.

“Your eyes aren’t looking where they need to look,” said Strayer, who has tried Google Glass (though not behind the wheel). Like Abadie, he noted that the law lags far behind the technology.

Legislators in at least three states — Delaware, New Jersey and West Virginia — have introduced bills that would specifically ban driving with Google Glass.

A spokesman for Google did not reply to a request for comment. On its website, Google says this about using the headgear while driving: “Read up and follow the law. Above all, even when you’re following the law, don’t hurt yourself or others by failing to pay attention to the road.”

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

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.
