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.
GloboNote is a desktop note taking application. It helps you to create to-do lists, reminders, and other notes in one place. There is no limit in the number of sticky notes you can create. Notes can be organized by groups and searched using the search tool. You can format a note's text, change its color, font, size, and transparency level. You can make a note sticky by setting it to always stay on top, or hide or roll-up a note when not use. You can set alarms, play custom alarm sounds (WAV, MP3, AIFF, and AU), attach files, insert images, and more.
The MOEA Framework is a Java library for developing and experimenting with multiobjective evolutionary algorithms (MOEAs) and other general-purpose optimization algorithms and metaheuristics. A number of algorithms are provided out-of-the-box, including NSGA-II, ε-MOEA, GDE3, and MOEA/D.
documentr is a Web-based tool for editing and presenting software documentation. It allows you to easily maintain documentation for multiple products and product branches. Edits can easily be copied between branches, with merge conflicts being handled gracefully. It uses Markdown as its markup language, along with some extensions, and has a role-based permission system.
DKPro Core is a collection of software components for natural language processing (NLP) based on the Apache UIMA framework. Many powerful and state-of-the-art NLP components are already freely available in the NLP research community. New and improved components are being developed and released continuously. The components cover the whole range of NLP-related processing tasks. DKPro Core provides wrappers for such third-party tool as well as original NLP components. DKPro Core builds heavily on uimaFIT which allows for rapid and easy development of NLP processing pipelines.
TomP2P is a P2P-based high performance key-value pair storage library. Each peer has a table (either disk-based or memory-based) to store its values. A single value can be queried or updated with a secondary key. The underlying communication framework uses Java NIO to handle many concurrent connections.
BlackHole is an data de-duplicating network block device that also supports mirroring, snapshots, and support for multiple LUNs using the same data store. It is filesystem agnostic and has been tested with ext2/3/4, NTFS, ReiserFS, and the Oracle Cluster File System (OCFS2). It supports encryption, compression, and multiple storage backends. The hashing scheme used is user configurable. The program exports an NBD device which can be mounted in Linux and GNU/Hurd.
Dash Reports is a versatile and lightweight reporting solution. It allows users and administrators to create a large range of reports driven by SQL databases. It also supports the creation of complex and powerful dashboards, with local caching of results to reduce load on the source database. Various report output formats are supported and the results can be styled using templates. The system allows for scheduled or user-invoked reports, delivered via browser, file, FTP/SFTP, or email.
JID is a system which can deserialize, update, and reserialize a map of 100,000 entries in half a millisecond on an i7 at 3.40 GHz. Serialization/reserialization timings are largely independent of the size and complexity of the table entries. Incremental serialization/deserialization is used to achieve high performance.
