Add a Wolfram Demonstration to Your Site in One Easy Step

With nearly 8,000 interactive knowledge apps available on a huge variety of topics in the Wolfram Demonstrations Project, you're bound to find one—or more—that you want to share. Now you can easily embed any Demonstration you like on your own blog or website in one step. Watch this short video or read on to see how (we recommend viewing the video in full-screen mode):

How to Make Interactive Apps with CDF

A number of you have written us asking about interface design, Dynamic structures, and general starting tips for creating Wolfram Computable Document Format (CDF) files. I will present three examples of CDF files that will provide some insight into good practices. You should also read the recent Mathematica Q&A Series blog post about delivering CDF to your websites and blogs with the help of the CDF Web Deployment Wizard. This enables users to showcase their Mathematica projects online and share them with the global community. Let's have a look at some features that make CDF great, rising well above other platforms. For a more extensive list, please see the CDF comparison table. We will start with a short program that numerically solves the challenging problem of constrained global optimization by finding the minimum on a limited surface region. Think of finding the lowest point of an area of a mountain range. Dragging the 2D slider on the interface below automatically changes the surface geometry, and the CDF engine quickly recomputes the new minimum. This is reflected in the updated positions of the red dot. Drag and rotate the 3D graphics with the mouse to get a different view. Hold Ctrl while dragging to zoom (Command on a Mac) or hold Shift and drag to pan.

Explore the Computable Document Format: Free Virtual Workshop

Ever since we launched the Computable Document Format (CDF) last summer, people have been excited about the ease of deploying interactive documents to their clients and on their websites, and we're seeing CDFs used to enhance blogs, textbooks, and other applications in many different areas. Now we're holding a virtual workshop where you can hear from the author of an award-winning CDF textbook, chat with Wolfram experts in publishing and application development, and learn how to get started with your own projects. The Wolfram CDF Virtual Workshop will feature a keynote by Conrad Wolfram plus talks and Q&A sessions with Wolfram experts. The virtual event will be held Tuesday, April 24, at the following times: * 8am–noon Eastern Daylight Time (EDT); 1pm–5pm British Summer Time (BST) * Repeat session: 1pm–5pm EDT; 6pm–10pm BST Virtual seats are limited—see the event schedule and register today!

Analyzing Your Email with Mathematica

In Stephen Wolfram's recent blog post about personal analytics, he showed a number of plots generated by analyzing his archive of personal data. One of the most common pieces of feedback we received was that people wanted to know how they could perform the same kind of analysis on their own data. So in this blog post I'm going to show you how to analyze your email the same way Stephen Wolfram did. Naturally, we did all the data cleaning and analysis for Stephen's data in Mathematica, so we'll be using Mathematica for everything here as well. All the code can be downloaded here. Let's start with that really cool diurnal plot Stephen did of his outgoing email. This plot shows the date and time each email was sent, with years running along the x axis and times of day on the y axis:
