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.

The Finch is a new robot for computer science education. Its design is the result of a four year study at Carnegie Mellon's CREATE lab. The Finch is made to easily integrate into high school and college CS courses. Institutions piloting the Finch have shown improved retention and year-over-year enrollment growth in their CS1 courses.

Most computer users have a haunting fear that somehow malware will find a way to sneak onto their PCs  when they are not looking. The truth is that while this does sometimes happen, the most common types of malware rely on trickery to invade and infect your computer.

With the grandiose bluster that only an aging juggernaut can pull off, Microsoft has detailed the Internet Explorer Performance Lab and its extraordinary efforts to ensure that IE9 is competitive, and that IE10 is the fastest browser in the world. Here's a few bullet points to reel you in: 140 computers, 20,000 tests per day, over 850 metrics analyzed, and a granularity of just 100 nanoseconds.

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

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.

Google has made no secret about its plans for Android. Smartphones and tablets are just the beginning - the company wants Android everywhere. And thanks to FXI Technologies' Cotton Candy USB device, we may not have to wait long to see Android on more than just our mobile devices.

"In the space of one hour, my entire digital life was destroyed. First my Google account was taken over, then deleted. Next my Twitter account was compromised, and used as a platform to broadcast racist and homophobic messages. And worst of all, my AppleID account was broken into, and my hackers used it to remotely erase all of the data on my iPhone, iPad, and MacBook."
