SnappyJ is a Java library designed to ease Web 2.0 development. It was developed to take the pain out of developing Web pages that asynchronously reload sections of themselves. Performing these types of asynchronous reloads properly and professionally is harder than one might initially expect. The key challenges are loading Indication, support for browser history, error handling, code complexity, and having reloadable sections that interact with each other. SnappyJ completely eliminates these challenges, making it quick and easy to develop complex application-like Web sites.
Algorithm Study provides tools and resources to augment the traditional study of algorithms. It includes implementations of common and less-common algorithms in a variety of languages and visualization tools to help in gaining a deeper understanding of the algorithms. The algorithm implementations are each accompanied by a discussion of the asymptotic ("big O") run time and memory limits of the algorithm. Some implementations include discussion of how the algorithm or data structure is commonly used and comparisons with similar algorithms or data structures. All implementations have test cases that exercise their functionality. The visualization tool, Algorithm Visualizer, displays what happens as various algorithms do their work.
