C-ROADS C-ROADS is an award-winning computer simulation that helps people understand the long-term climate impacts of policy scenarios to reduce greenhouse gas emissions. It allows for the rapid summation of national greenhouse gas reduction pledges in order to show the long-term impact on our climate. Features MIT’s John Sterman of the Climate Interactive team explains C-ROADS science and confidence building at a US State Department side event in Copenhagen. Role of C-ROADS Building on the Kyoto Protocol and outcomes from the UN climate negotiations, individual nations are making proposals and pledges to reduce greenhouse gas emissions.

The Ultimate Guide to MOOCs: Learn For Free Online Many of the world’s elite Universities are now offering some of their best courses for people to learn free online. In just the last year, MOOCs (Massive Open Online Courses) have taken off with a mission to provide free and open higher education to anyone in the world with access to the Internet. The majority of the world’s top 100 elite Universities are now offering MOOCs through the different course platforms that are detailed in this guide. While you won’t get official accreditation for these free University courses (that’s coming soon) you should seize this golden opportunity to learn from the world’s leading professors.

VisIt About VisIt VisIt is an Open Source, interactive, scalable, visualization, animation and analysis tool. From Unix, Windows or Mac workstations, users can interactively visualize and analyze data ranging in scale from small (<101 core) desktop-sized projects to large (>105 core) leadership-class computing facility simulation campaigns. Users can quickly generate visualizations, animate them through time, manipulate them with a variety of operators and mathematical expressions, and save the resulting images and animations for presentations. VisIt contains a rich set of visualization features to enable users to view a wide variety of data including scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured, adaptive and unstructured meshes.

Thank you. 50 Open Source Mobile Tools In a relatively short period of time, mobile devices have become ubiquitous in the workplace. A recent survey of enterprise and small business workers found that just 3 percent of organizations ban their employees from using personal iPads or iPhones for business use, and only 7 percent ban Android devices. In fact, 40 percent of organizations provide iPhones for more than a quarter of employees, and 25 percent provide Android-based smartphones. The open source community has responded to this trend with a host of new projects, including solutions that help enterprises track and manage mobile devices, mobile development tools for creating new apps and open source apps that enable greater productivity. This month, we've put together a list of 50 of these tools that are worth notice. While there are many good open source mobile apps for home users, this list focuses instead on those that would be most useful in the workplace.

PSPP GNU PSPP is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package. PSPP is a stable and reliable application.

A Comparison of Five Free MOOC Platforms for Educators By the end of 2013, most top universities had started to offer some sort of MOOC (massive open online course). Now, we are starting to see the MOOC product move into both the corporate and the private realm. Companies like Google and Tenaris are using MOOCs for training their employees, MongoDB is educating developers through the MOOC medium and thousands of private instructors are teaching classes on sites like Udemy. If you are considering a MOOC for yourself or your organization, you’ll first need to determine which tool you will use to build the course. The following is an assessment of five popular free MOOC (and MOOC-like) platforms. edX

Mayavi - 3D scientific data visualization and plotting The Mayavi project includes two related packages for 3-dimensional visualization: Mayavi: A tool for easy and interactive visualization of data, with seamless integration with Python scientific libraries. TVTK: A Traits-based wrapper for the Visualization Toolkit, a popular open-source visualization library. These libraries operate at different levels of abstraction. TVTK manipulates visualization objects, while Mayavi lets you operate on your data, and then see the results.
