StudyEgg is a new tool that can be used to augment already existing educational content on the Internet by adding new learning features. With StudyEgg teachers can create quizzes based on YouTube videos like Khan Academy or any other freely available lesson/material. GradeCam enables teachers to grade assignments instantly with any document camera or webcam, no special tools needed. The data is then displayed, showing the teacher if all students understood the concepts. Tests can be created on the go to check what students have learned instead of testing them days or weeks later. GradeCam then lets users import the data easily into the gradebook service,  Always Prepped combines different educational resources and services like Khan Academy, Edmodo or Study Island and puts all the learning related data of the students into one unified dashboard. Also able to add non-educational data such as social data to the dashboard. For example, if the teacher knows that the parents of a particular student are getting divorced or that a grandparent has died, the teacher is able to add this information to the data set and can see immediately whether the performance in class might somewhat be related to the happenings in the student's personal life.

ost people use Microsoft PowerPoint to create presentations, however there are many other tools which enable creation of more dynamic presentations. One such example is the Prezi web application which is well known for its unique zooming UI. Similarly, Impress.js is a JavaScript library and a free alternative to Prezi. Unfortunately, Prezi comes with a huge price tag and Impress.js can only be utilized by developers. If you are a lay user who wishes to get the functionality of the aforementioned tools to create more innovative presentations, then try Infinite Canvas. As the name suggests, it is a web based canvas which can be used to add images for creating slides which can be zoomed (in and out) like Prezi and Impress.js.

Finding creative solutions to energy issues has become a major priority for Google co-founder and CEO Larry Page in recent years. For the obvious reasons -- a growing population, increasingly scarce resources, and climate change -- he believes that the corporate world needs to operate more sustainably, and he is determined to build the nation's first zero-carbon company. This means a business that ultimately is so energy efficient and uses so much clean power that it emits no greenhouse gas -- a very tall order indeed. Experts aren't sure whether it's even possible for a company to emit no carbon, but Google is trying to come as close to that goal as possible. "As we became a bigger user of energy, we wanted to make sure we were not just part of the problem, but part of the solution," says Urs Hölzle, Google's employee No. 8 and a senior vice president who oversees the company's green initiatives.

"We believe you should be able to export your information from Google products when you want to. We have a special engineering team called the Data Liberation Front which has one goal - to make it easier for our users to move their data in and out of Google products. That's useful if you want to store a copy of your information on your own computer, or if you want to leave Google for another product and take your information to the new service. We've launched a data liberation tool called Google Takeout which makes it easier to move data in and out of Google products. It's good to know that you can use Google Takeout to move your data in and out of Google products. "

"On Wednesday, February 8th, Wolfram Alpha will be adding a new, "Pro" option to its already existing services. Priced at a very reasonable $4.99 a month ($2.99 for students), the new services includes the ability to use images, files, and even your own data as inputs instead of simple text entry. The "reports" that Wolfram Alpha kicks out as a result of these (or any) query are also beefed up for Pro users, some will actually become interactive charts and all of them can be more easily exported in a variety of formats. We sat down with Stephen Wolfram himself to get a tour of the new features and to discuss what they mean for his goal of "making the world's knowledge computable.""

"The statement "I have read and agree with the Terms of Service" is the biggest lie on the web. We aim to fix that.

"The use of Twitter to collecting tweets around an event hashtag allowing participants to share and contribute continues to grow and has even become part of mass media events, various TV shows now having and publicising their own tag. This resource is often lost in time, only tiny snippets being captured in blog posts or summaries using tools like Storify, which often loose the richness of individual conversations between participants. It doesn't have to be this way. Using a combination of Google Spreadsheets as a data source and a simple web interface to add interactivity it's possible to let users explorer your entire event hashtag and replay any of conversations."
