PyMuTester is tool to facilitate Mutant Testing (a.k.a Mutant Analysis or Program Mutation) on software systems written in Python. Its main purpose is to assist you in improving your existing unit tests to cover missing checks and “loopholes” in your testing. It works by making small changes (technically known as mutants) to your Python application’s source code and re-running your unit tests over these mutated applications' source code. Since the mutants usually go against the specifications, your unit tests should fail in such tests. If the unit tests still pass, then that is an indication that your unit tests might have missed some checks.
PirateWall is a simple Twitter Client. It displays search results for a certain keyword or hashtag in realtime in a shell-based environment. It can also be configured to act as a data provider for many different visualization tools. For example, it is possible to use the client as a text generator for many XScreensaver applications like "apple2" or "starwars". When used in a Unix shell environment, colorized output can be generated.
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.
