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.
MO Auto add terms is a Drupal 6.x module that automatically assigns terms to your pages from their contents, titles, and comments. This makes it very useful to build a complete site index without worrying about missing a few terms here and there. It also allows you to offer tagging functionality to your users, even when you prevent them from adding terms (by hiding the taxonomy field), and yet have terms assigned to their posts. This assignment is done automatically with MO Auto add terms. The module can also add parent terms, remove terms that are not in the page anymore, recognize equivalents and synonyms, hide the taxonomy selection box from the edit page, limit the number of terms to add automatically, etc.
siqqel is a simple and lightweight framework which allows you to execute MySQL queries directly from your browser (by transforming them into JSON calls to a backend script), displaying the results of your queries within the structure of the calling HTML document. To issue a query and have its results displayed in a table of your HTML document, you simply put an SQL statement into the "sql" attribute of a <table> element and it will be executed when you open the HTML document in your browser. Your browser will wrap the SQL statement into a JSON call, and this call will be issued to a backend script on your server, which in turn issues the statement against your database server and returns the result set back to your browser. Your browser will display the result set in the according table. If you hover your mouse over the table, a "reload" icon will be displayed, allowing you to re-issue the SQL statement without the need to reload the whole page.
