Rakudo Perl 6
Rakudo is a Raku compiler targeting MoarVM, and the Java Virtual Machine, that implements the Raku specification. It is currently the only major Raku compiler in active development. Originally developed within the Parrot project, the Rakudo source code repository was split from the project in February 2009 so that it could be developed independently, although there were still many dependencies at the time. Rakudo is written in C, Raku, and the lightweight Raku subset NQP (Not Quite Perl). Rakudo Perl #14 was released in February 2009, codenamed ''Vienna'' after the Perl mongers group that had sponsored one of its developers since April 2008. Subsequent releases have used codenames based on Perl mongers groups. The first major release of a distribution of both compiler and modules (named "Rakudo *" or "Rakudo Star") was on July 29, 2010. Name The name "Rakudo" for the Raku compiler was first suggested by Damian Conway. "Rakudo" is short for "Rakuda-dō" (with a long 'o'; ...

Java Virtual Machine
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform. The JVM reference implementation is developed by the OpenJDK project as open source code and includes a JIT compiler called HotSpot. The commercially supported Java releases available from Oracle are based on the OpenJDK runtime. Eclipse OpenJ9 is another open source JVM for OpenJDK. JVM specification The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection ...

Perl Mongers
Perl Mongers is an international association of user groups for the Perl programming language, and part of The Perl Foundation. It was created as a stand-alone organization in 1998 by brian d foy and others, who formed the first group, the New York Perl Mongers (NY.pm), in August 1997 at the First O'Reilly Perl Conference. It joined the Perl Foundation in 2000. Member groups are conventionally referred to with a short-form name of their location followed by ".pm", which refers to the conventional filename extension for a Perl module. foy's original idea for the name of the first group was the Perl regular expression /New York Perl M((o, u)ngers, aniacs)*/,, but "Perl Mongers" overtook it. At the Second O'Reilly Perl Conference in 1998, foy and others helped to create many new user groups by providing a means for people to connect with others in their area.

Codename
A code name, codename, call sign, or cryptonym is a code word or name used, sometimes clandestinely, to refer to another name, word, project, or person. Code names are often used for military purposes, or in espionage. They may also be used in industrial counter-espionage to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names. Origins Achaemenid Empire The Achaemenid Empire under Darius I employed a network of spies called the King’s Eye or the King’s Ear. These agents operated under anonymity, and “King’s Eye” was not a specific person but rather a code name for the intelligence network that reported directly to the king. Punic Wars The Carthaginian general Hannibal Barca reportedly used coded re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Computer Programming
Computer programming or coding is the composition of sequences of instructions, called computer program, programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing source code, code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit. Proficient programming usually requires expertise in several different subjects, including knowledge of the Domain (software engineering), application domain, details of programming languages and generic code library (computing), libraries, specialized algorithms, and Logic#Formal logic, formal logic. Auxiliary tasks accompanying and related to programming include Requirements analysis, analyzing requirements, Software testing, testing, debugging (investigating and fixing problems), imple ...

Fork (software Development)
In software development, a fork is a codebase that is created by duplicating an existing codebase and, generally, is subsequently modified independently of the original. Software built from a fork initially has identical behavior as software built from the original code, but as the source code is increasingly modified, the resulting software tends to have increasingly different behavior compared to the original. A fork is a form of branching, but generally involves storing the forked files separately from the original; not in the repository. Reasons for forking a codebase include user preference, stagnated or discontinued development of the original software or a schism in the developer community. Forking proprietary software (such as Unix) is prohibited by copyright law without explicit permission, but free and open-source software, by definition, may be forked without permission. Etymology The word ''fork'' has been used to mean "to divide in branches, go separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Code Repository
In version control systems, a repository is a data structure that stores metadata for a set of files or directory structure. Depending on whether the version control system in use is distributed, like Git or Mercurial, or centralized, like Subversion, CVS, or Perforce, the whole set of information in the repository may be duplicated on every user's system or may be maintained on a single server. Some of the metadata that a repository contains includes, among other things, a historical record of changes in the repository, a set of commit objects, and a set of references to commit objects, called ''heads''. The main purpose of a repository is to store a set of files, as well as the history of changes made to those files. Exactly how each version control system handles storing those changes, however, differs greatly. For instance, Subversion in the past relied on a database instance but has since moved to storing its changes directly on the filesystem. These differences in stora ...

Parrot Virtual Machine
Parrot is a discontinued register-based process virtual machine designed to run dynamic languages efficiently. It is possible to compile Parrot assembly language and Parrot intermediate representation (PIR, an intermediate language) to Parrot bytecode and execute it. Parrot is free and open-source software. Parrot was started by the Perl community and developed with help from the open-source and free software communities. As a result, it was focused on license compatibility with Perl ( Artistic License 2.0), platform compatibility across a broad array of systems, processor architecture compatibility across most modern processors, speed of execution, small size (around 700k depending on platform), and the flexibility to handle the varying demands made by Raku and other modern dynamic languages. Version 1.0, with a stable application programming interface (API) for development, was released on March 17, 2009. The last version is release 8.1.0 "Andean Parakeet". Parrot w ...

MoarVM
MoarVM (''Metamodel On A Runtime Virtual Machine'') is a virtual machine built for the 6model object system. It is being built to serve as yet another VM backend for Raku. MoarVM was created to allow for greater efficiency than Parrot by having a closer internal representation to the model system used by Raku. Notably it was the virtual machine for the first stable version of Rakudo released in December 2015. Work began on MoarVM on March 31, 2012; the project was first publicly announced the following year on May 31, 2013. As of March 2014, it is the fastest virtual machine for Rakudo and NQP in terms of startup time and build speed.
