GHCN Processor is a command-line tool that reads temperature data from the Global Historical Climatic Network (GHCN) database and produces an annual or monthly temperature series in CSV format for an arbitrary set of stations. Stations are filtered based on a simple EL expression passed to the tool. For example, you can select only stations that are in the Northern Hemisphere, in hilly and rural locations. You can also select stations that started reporting in a given year, and so on. The tool supports more than one method of grid partitioning, station combination, and can use both the adjusted data and raw unadjusted data.
Dummy Data Generator is a tool that generates dummy data for populating systems for testing. The data includes names, addresses, email addresses, phone numbers, and social "connections". Names are generated by using US Census data on the most common names. Email addresses are just a random string for the user portion and always use "example.com" for the domain. Currently the only output format is CSV.
The Apache Traffic Server (TS or ATS) is a modular, high-performance reverse proxy server, generally comparable to Squid. It was created by Inktomi, and distributed as a commercial product called the Inktomi Traffic Server, before Inktomi was acquired by Yahoo!. Traffic Server has been actively used inside of Yahoo for over 4 years, serving billions of requests every day. As of fall 2009, Traffic Server is an Open Source project, and in April 2010 the Apache Traffic Server was promoted to a top-level project of the ASF.
ContiPerf is a lightweight testing utility to easily leverage JUnit 4 test cases as performance tests, e.g. for continuous performance testing. It is inspired by JUnit 4's easy test configuration with annotations, and by JUnitPerf's idea of wrapping Unit tests for performance testing, but is more powerful and easier to use. It uses Java annotations for defining test execution characteristics and performance requirements. You can mark a test to run a certain number of times, or to be repeatedly executed for a certain amount of time. Performance requirements can be maximum, average, medium, or any percentile execution time. You can run tests in two different modes, using them as simple unit tests or performance tests. Easy integration with Eclipse and Maven. Export of an execution summary to a CSV file. A small library without external dependencies (only JUnit).
TinyIDS is a distributed intrusion detection system (IDS) for Unix systems. It is based on the client/server architecture and has been developed with security in mind. The client, tinyids, collects information from the local system by running its collector backends. The collected information may include anything, from file contents to file metadata or even the output of system commands. The client passes all this data through a hashing algorithm and a unique checksum (hash) is calculated. This hash is then sent to one or more TinyIDS servers (tinyidsd), where it is compared with a hash that had previously been stored in the databases of those remote servers for this specific client. A response indicating the result of the hash comparison is finally sent back to the client. Management of the remotely stored hash is possible through the client's command line interface. Communication between the client and the server can be encrypted using RSA public key infrastructure (PKI).
OrientDB is a NoSQL DBMS which can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.
