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

Do you want to build a game for Android, a theme for your blog or a twitter desktop client? Have a great idea but lack the development chops to take it from the pages of your legal pad to the App Store? Want to make sure your kid learns to program, even though your local school system may not offer the best options? This post should give you a good starting point for learning to program.

What makes a great software engineer and perhaps more importantly, what skills will most likely land you a sweet job?  Mixtent and KISSMetrics analyzed LinkedIn data and surveyed users on perceptions of candidate skill levels based on their profiles and purported skill sets.

Here are two tools that can be used for creating effective and engaging simulations.

n this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. Google is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems. The prototype with a full text and hyperlink database of at least 24 million pages is available at http://google.stanford.edu/

Eleven Equations True Computer Science Geeks Should (at Least Pretend to) Know

Can you crack this code?

Does flicking a dice really render a random face? The answer would be no.

This site was created to show you how your browser helps keep you secure online.

Last year we introduced HTTPS by default for Gmail and encrypted search. We're pleased to see that other major communications sites are following suit and deploying HTTPS in one form or another. We are now pushing forward by enabling forward secrecy by default. Most major sites supporting HTTPS operate in a non-forward secret fashion, which runs the risk of retrospective decryption. In other words, an encrypted, unreadable email could be recorded while being delivered to your computer today. In ten years time, when computers are much faster, an adversary could break the server private key and retrospectively decrypt today's email traffic.

This collection of links and applications highlights just the tip of the iceberg of educational resources that are available on the web. If you are interested in teaching yourself a new skill or learning a new topic indepth in your spare time, hopefully some of these will be of use. ** Collection of Computer Science courses **

Would you like to try out Google's Android OS on your netbook or desktop?  Here's how you can run Android from a flash drive and see how fast Android can run on real hardware!

With the help of LiveAndroid you don't have to wait to try it out. LiveAndroid has been around for a while now. Originally launched in May, LiveCD allows you to run the Android OS on x86 platforms without actually installing the software. Up until now this was only useful to those with netbooks that actually have an optical drive. However, the folks at LiveAndroid last week announced a LiveUSB version, especially handy for those of you with netbooks or notebooks that don't have a disc drive.

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.

This website teaches computer programming. Programming is a very useful skill: you can write programs to automate computer tasks, make art and music, interpret and process data, create software for others to use, run custom websites, and build upon code developed by other people, for example.

We present results of a 45-participant laboratory study investigating the usability of tools to limit online behavioral advertising (OBA).We tested nine tools, including tools that block access to advertising websites, tools that set cookies indicating a user's preference to opt out of OBA, and privacy tools that are built directly into web browsers.

Be prepared for when the web uses IPv6.
