The Geomajas API project contains some annotations that can be used to indicate which parts (which classes and which (public) methods or fields) are considered as the API. This is particularly useful for projects where you want to mark the API without the need to refactor everything to interfaces and factories.
jWeb1T is an Java tool for efficiently searching n-gram data in the Web 1T 5-gram corpus format. It is based on a binary search algorithm that finds the n-grams and returns their frequency counts in logarithmic time. As the corpus is stored in many files, a simple index is used to retrieve the files containing the n-grams.
Netscape Security Wrapper manages the loading of NPAPI (Netscape Plugin API) plugins and applies simple policy decisions. The intention is to allow administrators to deploy deprecated, unreliable, or unsafe third party plugins while minimizing the security exposure. Safari, Google Chrome, Firefox, and other NPAPI-compatible browsers are supported on OS X and Linux. Use cases include: restricting plugins to certain domains, restricting the use of deprecated plugins to known outliers, allowing internal corporate workflows which use insecure or deprecated plugins without exposing the plugin to the hostile Internet, and allowing multiple outdated plugin versions (e.g., Java) to co-exist for use in whitelisted, trusted enterprise tools.
RegressionSuite is a software test suite that incorporates measurements of startup lag and accurate execution times, generating execution statistics, customized input distributions, and processable regression specific details as part of the regular unit tests. It provides a framework around which the individual unit regressors are invoked (and details and statistics collected). Unit regressors are grouped into named regressor sets (or modules), and regressors are created by implementing specific regressor interfaces. These two features make regressors particularly amenable to testing analytics (and other similarly state-light) modules.
