The Artistic License refers most commonly to the original Artistic License ( version 1. 0 ), a software license used for certain free and open source software packages, most notably the standard Perl implementation and most CPAN modules, which are dual-licensed under the Artistic License and the GNU General Public License ( GPL ).

Abstraction allows program designers to separate categories and concepts from instances of implementation, so that they do not depend on software or hardware.

Acceptance testing is a term used in agile software development methodologies, particularly Extreme Programming, referring to the functional testing of a user story by the software development team during the implementation phase.

In practice, however, the performance gain is far less, only about 50 %, due to imperfect software algorithms and implementation.

Design and implementation of software varies depending on the complexity of the software.

Within software engineering, programming ( the implementation ) is regarded as one phase in a software development process.

Diagram illustrating the position of CAAC in relation to other Generative music SystemsComputer-Aided Algorithmic Composition ( CAAC, pronounced " sea-ack ") is the implementation and use of algorithmic composition techniques in software.

The djbdns software package is a DNS implementation created by Daniel J. Bernstein due to his frustrations with repeated BIND security holes.

Under Eiffel's design, a software text should be able to reproduce its design documentation from the text itself, using a formalized implementation of the " Abstract Data Type ".

A free software implementation is provided by GNU Binutils.

* Fixed-point representation uses integer hardware operations controlled by a software implementation of a specific convention about the location of the binary or decimal point, for example, 6 bits or digits from the right.

Whatever strategy is used ( simple or mutual ), the level of protection strongly depends on the correctness of the implementation of the web browser and the server software and the actual cryptographic algorithms supported.

Rapid industry changes of a technical and / or economic nature will usually increase levels of structural unemployment, for example: widespread implementation of new machinery or software will require future employees to be trained in this area before seeking employment.

Mesa introduced several other innovations in language design and implementation, notably in the handling of software exceptions, thread synchronization, incremental compilation, and more.

* MagLev ( software ), an implementation of the Ruby programming language

With Ingo Molnar he wrote the original software implementation of RAID-1 and RAID-5 drivers of the Linux kernel.

He has also been a longtime advocate of using Mono-a free software implementation of Microsoft's. NET Framework-in GNOME.

An implementation of standard CORBA is found in the TANGO software, used in five European particle accelerators ( synchrotrons ).

Some organizations use them extensively in combination with a software development methodology to progress from initial specification to an implementation plan and to communicate that plan to an entire team of developers and stakeholders.

An implementation of a programming language provides a way to execute that program on one or more configurations of hardware and software.

CPython, the reference implementation of Python, is free and open source software and has a community-based development model, as do nearly all of its alternative implementations.

SuperMemo ( from " Super Memory ") is a learning method and software package developed by SuperMemo World and SuperMemo R & D with Piotr Wozniak in Poland from 1985 to the present.

* Piotr Woźniak ( researcher ), lead programmer of the SuperMemo learning software

In computer systems, an algorithm is basically an instance of logic written in software by software developers to be effective for the intended " target " computer ( s ), in order for the target machines to produce output from given input ( perhaps null ).

A notable example was Phil Katz's PKARC ( and later PKZIP, using the same ". zip " algorithm that WinZip and other popular archivers now use ); also other concepts of software distribution like freeware, postcardware like JPEGview and donationware like Red Ryder for the Macintosh first appeared on BBS sites.

Information is broken into chunks, and an algorithm ( usually computer software ) organises the user's reading and calculates the ideal time for the reader to review each chunk.

When a user types in a password on such a system, the password handling software runs through a cryptographic hash algorithm, and if the hash value generated from the user's entry matches the hash stored in the password database, the user is permitted access.

* Details of the RSADSI ( RSA Data Security, Inc .) cryptographic algorithm software were revealed, probably deliberately, through publication of alleged RC4 source on Usenet.

International standard ISO 1155 states that a longitudinal redundancy check for a sequence of bytes may be computed in software by the following algorithm:

* COmponent Detection Algorithm, a mass spectrometry and chemometrics software algorithm

Together they developed software and hardware implementations of the algorithm, including a custom VLSI chip.

It is unknown whether any hardware using the algorithm was ever sold, though many software implementations ( which did not pay any license fees to the inventors ) have been released.

Modern advances in software and computational power have even eliminated the need to use grids or tracking marks – the software analyzes the relative motion of colored pixels against other colored pixels and calculates the ' motion ' to create a camera-motion algorithm which can be used in compositing software to match the motion of composited elements to a moving background plate.

For example, a cryptographic algorithm may be implemented by hardware and software that is widely distributed among users.

In software, an " audio codec " is a computer program implementing an algorithm that compresses and decompresses digital audio data according to a given audio file format or streaming media audio format.

The first widely marketed software package to offer digital signature was Lotus Notes 1. 0, released in 1989, which used the RSA algorithm.

For this reason, methods based on introductory linear algebra texts are generally not suitable for implementation in software ; rather, one should consult contemporary numerical analysis sources for an algorithm like the one below, which does not amplify rounding errors unnecessarily.

The invention was concerned with efficient memory management for the simplex algorithm, and could be implemented by purely software means.

In the basic machine division used software subroutines, but optional divide hardware could be installed using a repeated subtraction algorithm.

A more complete list of available software categorized by algorithm and alignment type is available at sequence alignment software, but common software tools used for general sequence alignment tasks include ClustalW and T-coffee for alignment, and BLAST and FASTA3x for database searching.

Of those prime candidates, several were identified as probable prime using the open source program OpenPFGW, and one of them was proved prime using the ECPP algorithm implemented by the Titanix software.

In the absence of such a hardware instruction, an atomic operation may be synthesized through the use of a software mutual exclusion algorithm.
