Raku (programming Language)
Raku is a member of the Perl family of programming languages. Formerly known as Perl 6, it was renamed in October 2019. Raku introduces elements of many modern and historical languages. Compatibility with Perl was not a goal, though a compatibility mode is part of the specification. The design process for Raku began in 2000. History The Raku design process was first announced on 19 July 2000, on the fourth day of that year's Perl Conference, by Larry Wall in his ''State of the Onion 2000'' talk. At that time, the primary goals were to remove "historical warts" from the language; "easy things should stay easy, hard things should get easier, and impossible things should get hard"; a general cleanup of the internal design and APIs. The process began with a series of requests for comments or "RFCs". This process was open to all contributors, and left no aspect of the language closed to change. Once the RFC process was complete, Wall reviewed and classified each of the 361 reque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rakudo
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 Damian Conway (born 5 October 1964 in Melbourne, Aust ...

Compatibility Mode
A compatibility mode is a software mechanism in which a software either emulates an older version of software, or mimics another operating system in order to allow older or incompatible software or files to remain compatible with the computer's newer hardware or software. Examples of the software using the mode are operating systems and Internet Explorer. Operating systems A compatibility mode in an operating system is a software mechanism in which a computer's operating system emulates an older processor, operating system, and/or hardware platform in order to allow older software to remain compatible with the computer's newer hardware or software. This differs from a full-fledged emulator in that an emulator typically creates a virtual hardware architecture on the host system, rather than simply translating the older system's function calls into calls that the host system can understand. Examples include Classic Mode in Mac OS X and compatibility mode in Microsoft Windows, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filehandle
In Unix and Unix-like computer operating systems, a file descriptor (FD, less frequently fildes) is a process-unique identifier ( handle) for a file or other input/output resource, such as a pipe or network socket. File descriptors typically have non-negative integer values, with negative values being reserved to indicate "no value" or error conditions. File descriptors are a part of the POSIX API. Each Unix process (except perhaps daemons) should have three standard POSIX file descriptors, corresponding to the three standard streams: Overview In the traditional implementation of Unix, file descriptors index into a per-process maintained by the kernel, that in turn indexes into a system-wide table of files opened by all processes, called the . This table records the ''mode'' with which the file (or other resource) has been opened: for reading, writing, appending, and possibly other modes. It also indexes into a third table called the inode table that describes the ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sigil (computer Programming)
In computer programming, a sigil () is a symbol affixed to a variable name, showing the variable's datatype or scope, usually a prefix, as in $foo, where $ is the sigil. '' Sigil'', from the Latin '' sigillum'', meaning a "little sign", means ''a sign or image supposedly having magical power''. Sigils can be used to separate and demarcate namespaces that possess different properties or behaviors. Historical context The use of sigils was popularized by the BASIC programming language. The best known example of a sigil in BASIC is the dollar sign ("$") appended to the names of all strings. Many BASIC dialects use other sigils (like "%") to denote integers and floating point numbers and their precision, and sometimes other types as well. Larry Wall adopted shell scripting's use of sigils for his Perl programming language. In Perl, the sigils do not specify fine-grained data-types like strings and integers, but the more general categories of scalars (using a prefixed "$"), ar ...

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 ...

Git (software)
Git () is a distributed version control system: tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development. Its goals include speed, data integrity, and support for distributed, non-linear workflows (thousands of parallel branches running on different systems). "So I'm writing some scripts to try to track things a whole lot faster." Git was originally authored by Linus Torvalds in 2005 for development of the Linux kernel, with other kernel developers contributing to its initial development. Since 2005, Junio Hamano has been the core maintainer. As with most other distributed version control systems, and unlike most client–server systems, every Git directory on every computer is a full-fledged repository with complete history and full version-tracking abilities, independent of network access or a central server. Git is free and open-source software distributed under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mailing List
A mailing list is a collection of names and addresses used by an individual or an organization to send material to multiple recipients. The term is often extended to include the people subscribed to such a list, so the group of subscribers is referred to as "the mailing list", or simply "the list." Transmission may be paper-based or electronic. Each has its strength, although a 2022 article claimed that "direct mail still brings in the lion’s share of revenue for most organizations." Types At least two types of mailing lists can be defined: * an ''announcement list'' is closer to the original sense, where a "mailing list" of people was used as a recipient for newsletters, periodicals or advertising. Traditionally this was done through the postal system, but with the rise of email, the electronic mailing list became popular. This type of list is used primarily as a one-way conduit of information and may only be "posted to" by selected people. This may also be referred to by t ...

Libera Chat
Libera Chat, stylized Libera.Chat, is an IRC network for free and open source software projects. It was founded on 19 May 2021 by former Freenode staff members, after Freenode was taken over by Andrew Lee, founder of Private Internet Access. History Freenode In 2017, Christel Dahlskjaer, then the head of staff at Freenode, incorporated a new company called Freenode Limited and transferred ownership to technology entrepreneur Andrew Lee. In February 2021, Dahlskjaer added the logo of Shells, a company co-founded by Lee, to the Freenode website. Following criticism from staff, Dahlskjaer resigned from the leadership of Freenode, and Freenode staff elected Tom Wesley as the new head of staff. Lee allegedly removed a blog post explaining the leadership changes and, on 11 May, appointed a new person to oversee the Freenode infrastructure. Freenode staff resigned en masse, and some published statements outlining their view of what happened and claiming that Lee had been a ...

Internet Relay Chat
Internet Relay Chat (IRC) is a text-based chat system for instant messaging. IRC is designed for group communication in discussion forums, called '' channels'', but also allows one-on-one communication via private messages as well as chat and data transfer, including file sharing. Internet Relay Chat is implemented as an application layer protocol to facilitate communication in the form of text. The chat process works on a client–server networking model. Users connect, using a clientwhich may be a web app, a standalone desktop program, or embedded into part of a larger programto an IRC server, which may be part of a larger IRC network. Examples of programs used to connect include Mibbit, IRCCloud, KiwiIRC, and mIRC. IRC usage has been declining steadily since 2003, losing 60 percent of its users. In April 2011, the top 100 IRC networks served more than half a million users at a time. History IRC was created by Jarkko Oikarinen in August 1988 to replace a progr ...
