Raku (programming Language)
Raku is a member of the Perl family of programming languages. Formerly named 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 O'Reilly Open Source Convention, Perl Conference, by Larry Wall in his ''Perl#State of the Onion, 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"; and a general cleanup of the internal design and application programming interfaces (APIs). The process began with a series of Request for Comments (RFCs). This process was open to all contributors, and left no aspect of the language closed to chang ...

O'Reilly Open Source Convention
The O'Reilly Open Source Convention (OSCON) was an American annual convention for the discussion of free and open-source software. It was organized by publisher O'Reilly Media and was held each summer, mostly in Portland, Oregon, from 1999 to 2019. History OSCON grew out of The Perl Conference, but the amount of Perl content continued to decline each year. The first Perl Conference took place in 1997. The first OSCON was held in 1999. ;Notable events * The OpenOffice.org open source project was announced at the 2000 conference in Monterey. * The OpenStack open source project was launched at the 2010 conference. * OSCON has been the host to Larry Wall's State of the Onion keynotes. * All O'Reilly events were cancelled in response to the COVID-19 pandemic The COVID-19 pandemic (also known as the coronavirus pandemic and COVID pandemic), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), began with an disease outbreak, outbreak of COVID-19 ...

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 ("$") appended to the names of all strings. Many BASIC dialects use other sigils (like "%") to denote integers and floating-point numbers and their precision, and sometimes other types as well. Larry Wall adopted shell scripting's use of sigils for his Perl programming language. In Perl, the sigils do not specify fine-grained data types like strings and integers, but the more general categories of scalars (using a prefixed "$"), arra ...

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 software system, system that tracks versions of computer file, files. It is often used to control source code by Programmer, programmers who are software development, developing software collaboratively. Design goals of Git include speed, data integrity, and support for Distributed computing, distributed, non-linear workflows — thousands of parallel Branching (version control), branches running on different computers. "So I'm writing some scripts to try to track things a whole lot faster." As with most other distributed version control systems, and unlike most client–server systems, Git maintains a local copy of the entire Repository (version control), repository, also known as "repo", with history and version-tracking abilities, independent of Computer network, network access or a central Server (computing), server. A repository is stored on each computer in a standard directory (computing), directory with additional, Hidden f ... [...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. Mailing lists are often rented or sold. If rented, the renter agrees to use the mailing list only at contractually agreed-upon times. The mailing list owner typically enforces this by " salting" (known as "seeding" in direct mail) the mailing list with fake addresses and creating new salts for each time the list is rented. Unscrupulous renters may attempt to bypass salts by renting several lists and merging them to find common, valid addresses. Mailing list brokers exist to help organizations rent their lists. For some list owners, such as specialized niche publications or charitable groups, their lists may be some of their most valuable assets, and mailing list brokers help them maximize the value of their lists. Transmission may be paper-based or electronic. Each has its strengths, although a 2022 article claimed that compared to email, " di ...

Libera Chat
Libera Chat, stylized as 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 (entrepreneur), 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 (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 members resigned en masse, and some published statements outlining th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Relay Chat
IRC (Internet Relay Chat) is a text-based chat system for instant messaging. IRC is designed for Many-to-many, group communication in discussion forums, called ''#Channels, channels'', but also allows one-on-one communication via instant messaging, private messages as well as Direct Client-to-Client, 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 model, client–server networking model. Users connect, using a clientwhich may be a Web application, web app, a Computer program, 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 ways used to connect include the programs Mibbit, KiwiIRC, mIRC and the paid service IRCCloud. IRC usage has been declining steadily since 2003, losing 60 percent of its users by 2012. In April 2011, the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exegesis
Exegesis ( ; from the Ancient Greek, Greek , from , "to lead out") is a critical explanation or interpretation (philosophy), interpretation of a text. The term is traditionally applied to the interpretation of Bible, Biblical works. In modern usage, exegesis can involve critical interpretations of virtually any text, including not just religious texts but also philosophy, literature, or virtually any other genre of writing. The phrase ''Biblical exegesis'' can be used to distinguish studies of the Bible from other critical textual explanations. Textual criticism investigates the history and origins of the text, but exegesis may include the study of the historical and cultural backgrounds of the author, text, and original audience. Other analyses include classification of the type of literary genres presented in the text and analysis of grammar, grammatical and syntax, syntactical features in the text itself. Usage One who practices exegesis is called an ''exegete'' (; from Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Programming Perl
''Programming Perl'', best known as the Camel Book among programmers, is a book about writing programs using the Perl programming language, revised as several editions (1991–2012) to reflect major language changes since Perl version 4. Editions have been co-written by the creator of Perl, Larry Wall, along with Randal L. Schwartz, then Tom Christiansen and then Jon Orwant. Published by O'Reilly Media, the book is considered the canonical reference work for Perl programmers. With over 1,000 pages, the various editions contain complete descriptions of each Perl language version and its interpreter. Examples range from trivial code snippets to the highly complex expressions for which Perl is widely known. The camel book editions are also noted for being written in an approachable and humorous style. History The first edition, which gained the nickname "the pink camel" due to its pink spine, was originally published in January 1991 and covered version 4 of the Perl language. It w ...
