The computer program avida is an auto-adaptive genetic system designed primarily for use as a platform in Digital or Artificial Life research. The avida system is based on concepts similar to those employed by the tierra program developed by Tom Ray. It is a population of self-reproducing strings with a Turing-complete genetic basis subjected to Poisson-random mutations. The population adapts to the combination of an intrinsic fitness landscape (self-reproduction) and an externally imposed (extrinsic) fitness function provided by the researcher. By studying this system, one can examine evolutionary adaptation, general traits of living systems (such as self-organization), and other issues pertaining to theoretical or evolutionary biology and dynamic systems.

The European Molecular Biology Open Software Suite (EMBOSS) is a comprehensive set (about 100) of open source tools for genetic sequence analysis. EMBOSS is produced by the European Molecular Biology Network (EMBnet - http://www.embnet.org/). All EMBOSS tools are all built around the same set of core libraries - AJAX and NUCLEUS - and therefore share a unified user interface, have similar "look and feel", and implement a uniform sequence addressing methodology. The various components of EMBOSS are distributed under the GPL, except the core libraries which are under the LGPL. EMBASSY packages are third party applications which have been integrated with the EMBOSS suite, but which are not included in the base EMBOSS distribution for licensing or other reasons. The EMBASSY packages live in the biology/embassy port.

OpenSCAD is a software for creating 3D CAD objects. Unlike most free software for creating 3D models, it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it is more suitable for creating 3D models of machine parts but perhaps not when creating computer-animated movies. OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. This gives designers full control over the modelling process and enables them to easily change any step in the modelling process or make designes that are defined by configurable parameters.

MariaDB is a database server that offers drop-in replacement functionality for MySQL. MariaDB is built by some of the original authors of MySQL, with assistance from the broader community of Free and open source software developers. In addition to the core functionality of MySQL, MariaDB offers a rich set of feature enhancements including alternate storage engines, server optimizations, and patches. MariaDB is primarily driven by developers at Monty Program, a company founded by Michael "Monty" Widenius, the original author of MySQL, but this is not the whole story about MariaDB. On the "About MariaDB" page you will find more information about all participants in the MariaDB community, including storage engines XtraDB and PBXT.

PEAR::DB is a database abstraction layer providing: * an OO-style query API * portability features that make programs written for one DBMS work with other DBMS's * a DSN (data source name) format for specifying database servers * prepare/execute (bind) emulation for databases that don't support it natively * a result object for each query response * portable error codes * sequence emulation * sequential and non-sequential row fetching as well as bulk fetching * formats fetched rows as associative arrays, ordered arrays or objects * row limit support * transactions support * table information interface * DocBook and phpDocumentor API documentation Drivers for the following extensions pass the complete test suite and provide interchangeability when all of DB's portability options are enabled: fbsql, ibase, informix, msql, mssql, mysql, mysqli, oci8, odbc, pgsql, sqlite and sybase.

Bugzilla is one example of a class of programs called "Defect Tracking Systems", or, more commonly, "Bug-Tracking Systems". Defect Tracking Systems allow individual or groups of developers to keep track of outstanding bugs in their product effectively. Bugzilla has matured immensely, and now boasts many advanced features. These include: * integrated, product-based granular security schema * inter-bug dependencies and dependency graphing * advanced reporting capabilities * a robust, stable RDBMS back-end * extensive configurability * a very well-understood and well-thought-out natural bug resolution protocol * email, XML, console, and HTTP APIs * available integration with automated software configuration management systems, including Perforce and CVS (through the Bugzilla email interface and checkin/checkout scripts) * too many more features to list

Essentially, this module is a very optimized version of Clone::More. By taking advantage of one of Clone::More's 'OPTIMIZATION_HACKS' as well as removing all the Pure Perl from the More.pm, I was able to gain a lot of speed out of the module. Essentially, though, the core of the module is exactly as that of Clone::More. You will see that by using Benchmark::cmpthese, I ran a simple comparison between Storable::dclone, Clone::More::clone, and Clone::Fast::clone. You will (should) begin to see the reason why I loaded this module along side of Clone::More. Rate Storable Clone::More Clone::Fast Storable 7552/s -- -39% -59% Clone::More 12400/s 64% -- -33% Clone::Fast 18442/s 144% 49% -- For more information relative to the DESCRIPTION of this module, I recommend peeking into the POD written for Clone::More (I took more time with it ;) )
