SQLite ( "S-Q-L-ite", "sequel-ite") is a free and open-source relational database engine written in the C programming language. It is not a standalone application; rather, it is a library that software developers embed in their applications. As such, it belongs to the family of embedded databases. According to its developers, SQLite is the most widely deployed database engine, as it is used by several of the top web browsers, operating systems, mobile phones, and other embedded systems.

MetaPost refers to both a programming language and the interpreter of the MetaPost programming language. Both are derived from Donald Knuth's Metafont language and interpreter. MetaPost produces vector graphic diagrams from a geometric/algebraic description. The language shares Metafont's declarative syntax for manipulating lines, curves, points and geometric transformations. However,

In computer-based language recognition, ANTLR (pronounced antler), or ANother Tool for Language Recognition, is a parser generator that uses a LL(*) algorithm for parsing. ANTLR is the successor to the Purdue Compiler Construction Tool Set (PCCTS), first developed in 1989, and is under active development. Its maintainer is Professor Terence Parr of the University of San Francisco.

Nostr (acronym for Notes and Other Stuff Transmitted by Relays) is an open protocol for decentralized message transmission, with the intention to be able to resist internet censorship while maintaining session integrity. "Noster" can also be translated as "our" or "ours" from Latin. The protocol achieves decentralization through users publishing content associated with a cryptographic public key to various "relays", which are WebSocket servers that store and distribute an activity stream of received data from users. This allows the network to verify users and achieve account portability on Nos

CSPro, short for the Census and Survey Processing System, is a public domain and Open source data collection and processing software package developed by the U.S. Census Bureau and ICF International. Serpro S.A. was involved in past development. Funding for development comes primarily from the U.S. Agency for International Development. The main purpose of this software suite is to design applications for data collection, processing and tabulation.

SAMtools is a set of utilities for interacting with and post-processing short DNA sequence read alignments in the SAM (Sequence Alignment/Map), BAM (Binary Alignment/Map) and CRAM formats, written by Heng Li. These files are generated as output by short read aligners like BWA. Both simple and advanced tools are provided, supporting complex tasks like variant calling and alignment viewing as well as sorting, indexing, data extraction and format conversion. SAM files can be very large (tens of Gigabytes is common), so compression is used to save space. SAM files are human-readable text files, an
