The Artistic License is a software license used for certain free and open-source software packages, most notably the standard implementation of the Perl programming language and most CPAN modules, which are dual-licensed under the Artistic License and the GNU General Public License (GPL).
The Comprehensive Perl Archive Network (CPAN) is a repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors. CPAN can denote either the archive network itself, or the Perl program that acts as an interface to the network and as an automated software installer. Most software on CPAN is free and open source software. CPAN was conceived in 1993 and active online since October 1995. It is based on the CTAN model and began as a place to unify the structure of scattered Perl archives.
In software development, obfuscation is the deliberate act of creating source or machine code that is difficult for humans to understand. Like obfuscation in natural language, it may use needlessly roundabout expressions to compose statements. Programmers may deliberately obfuscate code to conceal its purpose or its logic or implicit values embedded in it, primarily, in order to prevent tampering, deter reverse engineering, or even as a puzzle or recreational challenge for someone reading the source code. This can be done manually or by using an automated tool, the latter being the preferred technique in industry.
A regular expression, regex or regexp is a sequence of characters that define a search pattern. Usually this pattern is used by string searching algorithms for "find" or "find and replace" operations on strings, or for input validation. It is a technique developed in theoretical computer science and formal language theory.
Randal L. Schwartz, also known as merlyn, is an American author, system administrator and programming consultant.
A backdoor is a method, often secret, of bypassing normal authentication or encryption in a computer system, a product, or an embedded device, or its embodiment, e.g. as part of a cryptosystem, an algorithm, a chipset, or a "homunculus computer" —a tiny computer-within-a-computer. Backdoors are often used for securing remote access to a computer, or obtaining access to plaintext in cryptographic systems. The backdoor may be used to gain access to passwords, delete data on hard drives, or transfer information within the cloud.
Perl 6 is a member of the Perl family of programming languages.
A penetration test, colloquially known as a pen test, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system. The test is performed to identify both weaknesses, including the potential for unauthorized parties to gain access to the system's features and data, as well as strengths, enabling a full risk assessment to be completed.
Advanced Perl Programming is a 1997 book by Sriram Srinivasan which covers complex techniques needed in production level Perl.
Pugs is a compiler and interpreter for the Perl 6 programming language, started on February 1, 2005, by Audrey Tang.
In computer science, the syntax of a computer language is the set of rules that defines the combinations of symbols that are considered to be a correctly structured document or fragment in that language. This applies both to programming languages, where the document represents source code, and markup languages, where the document represents data. The syntax of a language defines its surface form. Text-based computer languages are based on sequences of characters, while visual programming languages are based on the spatial layout and connections between symbols. Documents that are syntactically invalid are said to have a syntax error.
Rakudo Perl 6 is a Perl 6 compiler targeting MoarVM, and the Java Virtual Machine, that implements the Perl 6 specification. It is currently the only major Perl 6 compiler in active development.
Padre is a multi-language software development platform comprising an IDE and a plug-in system to extend it. It is written primarily in Perl and is used to develop applications in this language.
The Perl virtual machine is a stack-based process virtual machine implemented as an opcodes interpreter which runs previously compiled programs written in the Perl language. The opcodes interpreter is a part of the Perl interpreter, which also contains a compiler in one executable file, commonly /usr/bin/perl on various Unix-like systems or perl.exe on Microsoft Windows systems.
The following outline is provided as an overview of and topical guide to the Perl programming language:
Amavis is an open-source content filter for electronic mail, implementing mail message transfer, decoding, some processing and checking, and interfacing with external content filters to provide protection against spam and viruses and other malware. It can be considered an interface between a mailer and one or more content filters.
