A Periodic Table of Visualization Methods - mouse over each element to see the original.  Very cool.

Just change the table to be your own headings and numbers content (you may make more, or less, rows and/or columns). Resultant table is editable. Click any cell to change its value. Then click outside the table and all other charts change dynamically. Interesting way to create dynamic visualizations

Get ready with your "slow news day?" comments, because Microsoft has introduced an Achievement system to its Visual Studio programming environment and this is indeed a news story highlighting that fact.

Are you teaching Advanced Placement Computer Science? Are you looking for supplemental exercises that may help you students with the concepts? If so this announcement may be of interest to you. Pex for Fun has been around for a while offering coding duels in C#, F# and Visual Basic. Recently though it was decided to invest some time, money and effort to adapt some exercises specifically to help learn APCS concepts. Most students find the differences between Java and C# pretty minor at this level so most APCS students will find this doable even if they have only been taught Java previously.

Throughout the year I try to share resources and information with you that I think will be helpful for you. Often times these resources will include links to free eBooks that we make available on a variety of topics. Today, I thought I would post a large collection of eBooks for you here so that you can find them in one place and consume them as you see fit. Also, if you find this list helpful, please share it with your peers and colleagues so that they too can benefit from these resources.

Welcome to the distribution center for BYOB (Build Your Own Blocks), an advanced offshoot of Scratch, a visual programming language primarily for kids from the Lifelong Kindergarten Group at the MIT Media Lab. This version, developed by Jens Mönig with design input and documentation from Brian Harvey, is an attempt to extend the brilliant accessibility of Scratch to somewhat older users-in particular, non-CS-major computer science students-without becoming inaccessible to its original audience. BYOB 3 adds first class lists, sprites, and procedures to BYOB's original contribution of custom blocks and recursion.

Anyone who has used Microsoft Excel since 1993 has likely dabbled at least once with VBA, or Visual Basic for Applications, scripting: That's the year Excel 5.0 arrived with VBA support. The feature allows users to create automated tasks and functions in the spreadsheet application, extending the software's potential.

Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production. » Free to download and open source » Interactive programs using 2D, 3D or PDF output » OpenGL integration for accelerated 3D » For GNU/Linux, Mac OS X, and Windows » Projects run online or as double-clickable applications » Over 100 libraries extend the software into sound, video, computer vision, and more... » Well documented, with many books available

Since 2007 Lero - the Irish Software Engineering Research Centre has been running an Education and Outreach Program to encourage students to discover and learn about computing and software development. We have developed Scratch lesson plans, to teach software development to students. Scratch is a visual programming language that makes it easy to create interactive stories, animations, games, music, and art and share these creations on the web.

This unit aims to teach students the fundamentals of games programming using Kodu, which is a visual game development environment. Using Kodu students will understand how to build a world and program characters and objects before moving on to designing their own games. Each lesson has a PowerPoint file that outlines the tasks.

Lazarus is a free and open source development tool for the Free Pascal compiler, which is also free and open source.
