51-636: Illumination was created by Bryan Lunduke , and first released in May 2010. The earliest known public mention of Illumination was on the April 11, 2010 episode of The Linux Action Show! . On June 6, 2012 the Illumination was released as open source software , as attempt to innovate a donation -driven Business model for open-source software . After initially achieving the requested amount of money, on July 12, 2012 deficit of target sums from donations resulted in

102-416: A client–server networking model . Users connect, using a client—which may be a web app , a standalone desktop program , or embedded into part of a larger program—to 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,

153-468: A "Window Editor" to allow for the building of applications with simple user interfaces. As of 2.0, Illumination Software Creator supports creating Python ( PyGTK ) applications as two distinct targets: Desktop and Maemo Tablet. And also supports creating Adobe Flex based rich Internet applications that run on the Adobe Flash platform. At version 2.1 support for building Android applications

204-544: A Latin letter "+o"/"o"). On most networks, an operator can: There are also users who maintain elevated rights on their local server, or the entire network; these are called IRC operators, sometimes shortened to IRCops or Opers (not to be confused with channel operators). As the implementation of the IRCd varies, so do the privileges of the IRC operator on the given IRCd. RFC 1459 claims that IRC operators are "a necessary evil" to keep

255-732: A clean state of the network, and as such they need to be able to disconnect and reconnect servers. Additionally, to prevent malicious users or even harmful automated programs from entering IRC, IRC operators are usually allowed to disconnect clients and completely ban IP addresses or complete subnets. Networks that carry services (NickServ et al.) usually allow their IRC operators also to handle basic "ownership" matters. Further privileged rights may include overriding channel bans (being able to join channels they would not be allowed to join, if they were not opered), being able to op themselves on channels where they would not be able without being opered, being auto-opped on channels always and so forth. A hostmask

306-416: A common solution is to use IRCv3 "multi-prefix" extension. Many daemons and networks have added extra modes or modified the behavior of modes in the above list. A channel operator is a client on an IRC channel that manages the channel. IRC channel operators can be easily seen by the symbol or icon next to their name (varies by client implementation, commonly a "@" symbol prefix, a green circle, or

357-420: A network of IRC servers is a tree . Messages are routed along only necessary branches of the tree but network state is sent to every server and there is generally a high degree of implicit trust between servers. However, this architecture has a number of problems. A misbehaving or malicious server can cause major damage to the network and any changes in structure, whether intentional or a result of conditions on

408-412: A server or the entire network), IRCop only communications: GlobOps, +H mode showing that an IRCop is a "helpop" etc. Much of DALnet's new functions were written in early 1995 by Brian "Morpher" Smith and allow users to own nicknames, control channels, send memos, and more. In July 1996, after months of flame wars and discussions on the mailing list, there was yet another split due to disagreement in how

459-504: A server use '&'. Other less common channel types include '+' channels—'modeless' channels without operators —and '!' channels, a form of timestamped channel on normally non-timestamped networks. Users and channels may have modes that are represented by individual case-sensitive letters and are set using the MODE command. User modes and channel modes are separate and can use the same letter to mean different things (e.g. user mode "i"

510-447: Is a podcasting network formed by Chris Fisher and Bryan Lunduke in May 2008 following the initial success of The Linux Action Show! In 2008, the company had two shows The Linux Action Show! and CastaBlasta . By 2017, they were producing nine video and audio podcasts. In September of 2018, Jupiter Broadcasting announced their merger with Linux Academy, a Linux and cloud training platform. In December of 2019, Linux Academy

561-415: 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

612-419: Is a unique identifier of an IRC client connected to an IRC server . IRC servers , services , and other clients, including bots , can use it to identify a specific IRC session. The format of a hostmask is nick!user@host . The hostmask looks similar to, but should not be confused with an e-mail address . The nick part is the nickname chosen by the user and may be changed while connected. The user part

663-406: Is delivered in a fashion similar to multicast , meaning each message travels a network link exactly once. This is a strength in comparison to non-multicasting protocols such as Simple Mail Transfer Protocol (SMTP) or Extensible Messaging and Presence Protocol (XMPP) . An IRC daemon can be used on a local area network (LAN). IRC can thus be used to facilitate communication between people within

714-533: Is encouraged during live streams. As of early 2017, all shows from the main JB1 studio are being streamed using Linux and open source technologies. All remaining proprietary software had been removed and replaced by free alternatives which, according to Fisher, does not present any type of downgrade to the content's quality. Jupiter Broadcasting has been an annual media sponsor for LinuxFest Northwest since 2008. IRC channel IRC ( Internet Relay Chat )

765-422: Is invisible mode while channel mode "i" is invite only. ) Modes are usually set and unset using the mode command that takes a target (user or channel), a set of modes to set (+) or unset (-) and any parameters the modes need. Some channel modes take parameters and other channel modes apply to a user on a channel or add or remove a mask (e.g. a ban mask) from a list associated with the channel rather than applying to

816-477: Is the username reported by ident on the client. If ident is not available on the client, the username specified when the client connected is used after being prefixed with a tilde . The host part is the hostname the client is connecting from. If the IP address of the client cannot be resolved to a valid hostname by the server, it is used instead of the hostname. Because of the privacy implications of exposing

867-825: The EFnet ircd version 2.8.10). It was meant to be just a test network to develop bots on but it quickly grew to a network "for friends and their friends". In Europe and Canada a separate new network was being worked on and in December the French servers connected to the Canadian ones, and by the end of the month, the French and Canadian network was connected to the US one, forming the network that later came to be called "The Undernet ". The "undernetters" wanted to take ircd further in an attempt to make it use less bandwidth and to try to sort out

918-607: The Finnish network. They had obtained the program from one of Oikarinen's friends, Vijay Subramaniam—the first non-Finnish person to use IRC. IRC then grew larger and got used on the entire Finnish national network— FUNET —and then connected to Nordunet , the Scandinavian branch of the Internet. In November 1988, IRC had spread across the Internet and in the middle of 1989, there were some 40 servers worldwide. In August 1990,

969-535: The IP address or hostname of a client, some IRC daemons also provide privacy features, such as InspIRCd or UnrealIRCd's "+x" mode. This hashes a client IP address or masks part of a client's hostname, making it unreadable to users other than IRCops . Users may also have the option of requesting a "virtual host" (or "vhost"), to be displayed in the hostmask to allow further anonymity. Some IRC networks, such as Libera Chat or Freenode , use these as "cloaks" to indicate that

1020-475: The IRC command LIST , which lists all currently available channels that do not have the modes +s or +p set, on that particular network. Users can join a channel using the JOIN command, in most clients available as /join #channelname . Messages sent to the joined channels are then relayed to all other users. Channels that are available across an entire IRC network are prefixed with a '#', while those local to

1071-417: The IRC network. Users access IRC networks by connecting a client to a server. There are many client implementations, such as mIRC , HexChat and irssi , and server implementations, e.g. the original IRCd . Most IRC servers do not require users to register an account but a nickname is required before being connected. IRC was originally a plain text protocol (although later extended), which on request

1122-401: The IRC protocol have been published, there is no official specification, as the protocol remains dynamic. Virtually no clients and very few servers rely strictly on the above RFCs as a reference. Microsoft made an extension for IRC in 1998 via the proprietary IRCX . They later stopped distributing software supporting IRCX, instead developing the proprietary MSNP . The standard structure of

1173-463: The Internet. New server software has added a multitude of new features. As of 2016 , a new standardization effort is under way under a working group called IRCv3, which focuses on more advanced client features such as instant notifications, better history support and improved security. As of 2019 , no major IRC networks have fully adopted the proposed standard. As of June 2021, there are 481 different IRC networks known to be operating, of which

1224-508: The US side. Most (not all) of the IRCnet servers were in Europe, while most of the EFnet servers were in the US. This event is also known as "The Great Split" in many IRC societies. EFnet has since (as of August 1998) grown and passed the number of users it had then. In the (northern) autumn of the year 2000, EFnet had some 50,000 users and IRCnet 70,000. IRC has changed much over its life on

1275-444: The channel as a whole. Modes that apply to users on a channel have an associated symbol that is used to represent the mode in names replies (sent to clients on first joining a channel and use of the names command) and in many clients also used to represent it in the client's displayed list of users in a channel or to display an own indicator for a user's modes. In order to correctly parse incoming mode messages and track channel state

1326-531: The channel chaos ( netsplits and takeovers ) that EFnet started to suffer from. For the latter purpose, the Undernet implemented timestamps, new routing and offered the CService—a program that allowed users to register channels and then attempted to protect them from troublemakers. The first server list presented, from 15 February 1993, includes servers from the U.S., Canada, France, Croatia and Japan. On 15 August,

1377-418: The client does not recognize) passed directly to the server, possibly with some modification. Due to the nature of the protocol, automated systems cannot always correctly pair a sent command with its reply with full reliability and are subject to guessing. The basic means of communicating to a group of users in an established IRC session is through a channel . Channels on a network can be displayed using

1428-455: The client must know which mode is of which type and for the modes that apply to a user on a channel which symbol goes with which letter. In early implementations of IRC this had to be hard-coded in the client but there is now a de facto standard extension to the protocol called ISUPPORT that sends this information to the client at connect time using numeric 005. There is a small design fault in IRC regarding modes that apply to users on channels:

1479-488: The community nature of IRC there are a large number of other networks for users to choose from. Historically the "Big Four" were: IRC reached 6 million simultaneous users in 2001 and 10 million users in 2004–2005, dropping to around 350k in 2021. The top 100 IRC networks have around 230k users connected at peak hours. Timeline of major servers: IRC is an open protocol that uses TCP and, optionally, TLS . An IRC server can connect to other IRC servers to expand

1530-516: The development of the ircd should evolve. Most notably, the "European" (most of those servers were in Europe) side that later named itself IRCnet argued for nick and channel delays whereas the EFnet side argued for timestamps. There were also disagreements about policies: the European side had started to establish a set of rules directing what IRCops could and could not do, a point of view opposed by

1581-399: The first major disagreement took place in the IRC world. The "A-net" (Anarchy net) included a server named eris.berkeley.edu. It was all open, required no passwords and had no limit on the number of connects. As Greg "wumpus" Lindahl explains: "it had a wildcard server line, so people were hooking up servers and nick-colliding everyone". The "Eris Free Network", EFnet , made the eris machine

1632-451: The first to be Q-lined (Q for quarantine) from IRC. In wumpus' words again: "Eris refused to remove that line, so I formed EFnet. It wasn't much of a fight; I got all the hubs to join, and almost everyone else got carried along." A-net was formed with the eris servers, while EFnet was formed with the non-eris servers. History showed most servers and users went with EFnet. Once A-net disbanded, the name EFnet became meaningless, and once again it

1683-418: The functionality of a software application. Like many other Visual programming languages , Illumination does not require any code to be written by hand in order to develop software. Within Illumination each "Block" is a self-contained piece of functionality. Blocks are tied together via "inputs" and "outputs" which pass no data, and only serve to structure the flow of the application. Illumination also contains

1734-405: The local area network (internal communication). IRC has a line-based structure. Clients send single-line messages to the server, receive replies to those messages and receive copies of some messages sent by other clients. In most clients, users can enter commands by prefixing them with a '/'. Depending on the command, these may either be handled entirely by the client, or (generally for commands

1785-402: The names message used to establish initial channel state can only send one such mode per user on the channel, but multiple such modes can be set on a single user. For example, if a user holds both operator status (+o) and voice status (+v) on a channel, a new client will be unable to see the mode with less priority (i.e. voice). Workarounds for this are possible on both the client and server side;

1836-474: The new user count record was set to 57 users. In May 1993, RFC 1459 was published and details a simple protocol for client/server operation, channels, one-to-one and one-to-many conversations. A significant number of extensions like CTCP, colors and formats are not included in the protocol specifications, nor is character encoding, which led various implementations of servers and clients to diverge. Software implementation varied significantly from one network to

1887-528: The open source Libera Chat , founded in May 2021, has the most users, with 20,374 channels on 26 servers; between them, the top 100 IRC networks share over 100 thousand channels operating on about one thousand servers. After its golden era during the 1990s and early 2000s (240,000 users on QuakeNet in 2004), IRC has seen a significant decline, losing around 60% of users between 2003 and 2012, with users moving to social media platforms such as Facebook or Twitter , but also to open platforms such as XMPP which

1938-538: The other, each network implementing their own policies and standards in their own code bases. During the summer of 1994, the Undernet was itself forked. The new network was called DALnet (named after its founder: dalvenjah), formed for better user service and more user and channel protections. One of the more significant changes in DALnet was use of longer nicknames (the original ircd limit being 9 letters). DALnet ircd modifications were made by Alexei "Lefler" Kosut. DALnet

1989-504: The protocol implemented in the irc2.4.0 version of the IRC2 server, and documented in RFC 1459. Since RFC 1459 was published, the new features in the irc2.10 implementation led to the publication of several revised protocol documents (RFC 2810, RFC 2811, RFC 2812 and RFC 2813); however, these protocol changes have not been widely adopted among other implementations. Although many specifications on

2040-579: The source closing, and a fee being attached for download of binaries. On November 28, 2012 the source code for current versions became available for purchase, under a Personal Proprietary License, the GNU General Public License , and a BSD license. On November 28, 2012 the business model was changed, allowing download of all premium lunduke.com content, including this software, for a minimum donation of $ 2. Illumination works by arranging "building blocks" in order to visually describe

2091-813: The top 100 IRC networks served more than 200,000 users at a time. IRC was created by Jarkko Oikarinen in August 1988 to replace a program called MUT (MultiUser Talk) on a BBS called OuluBox at the University of Oulu in Finland , where he was working at the Department of Information Processing Science. Jarkko intended to extend the BBS software he administered, to allow news in the Usenet style, real time discussions and similar BBS features. The first part he implemented

2142-403: The underlying network, require a net-split and net-join. This results in a lot of network traffic and spurious quit/join messages to users and temporary loss of communication to users on the splitting servers. Adding a server to a large network means a large background bandwidth load on the network and a large memory load on the server. Once established, however, each message to multiple recipients

2193-677: Was acquired by A Cloud Guru . In August 2020, on Linux Unplugged 368 , Chris Fisher announced Jupiter Broadcasting would be independent again, and 2 shows, Coder Radio and Linux Action News , would resume. Linux Headlines would stay with A Cloud Guru. Most shows are streamed live through various platforms, such as their own website, Twitch , YouTube , and other audio-only formats. When not live, past episodes are available for streaming and download. Jupiter Broadcasting also uses social media , like an IRC channel for live chat, Mumble for Linux UNPLUGGED, Telegram , and most current shows have their own Twitter account. Viewer interaction

2244-642: Was added. For version 4.2, released on February 6, 2012, Portal Blocks have been added. The Illumination Software Creation Station is an Opensuse based Linux distribution, built with Susestudio , that provides a pre-setup system for testing and using Illumination Software Creator as a Live-CD or VMWare virtual machine. On Dec 16th, 2010, the Illumination Software Creation Station won the first annual Novell Disters award for best software appliance built with Susestudio . The Linux Action Show! Jupiter Broadcasting

2295-431: Was added. In version 2.2 support for building what are called "Custom Blocks" was added to allow developers to expand the functionality of their projects as needed using traditional programming languages (such as Java, Python and ActionScript). For version 3.0 support for building iOS applications was added. For version 4.0, released on September 7, 2011, support for building HTML5 applications and including graphics

2346-595: Was assigned port 194/TCP by IANA . However, the de facto standard has always been to run IRC on 6667/TCP and nearby port numbers (for example TCP ports 6660–6669, 7000) to avoid having to run the IRCd software with root privileges . The protocol specified that characters were 8-bit but did not specify the character encoding the text was supposed to use. This can cause problems when users using different clients and/or different platforms want to converse. All client-to-server IRC protocols in use today are descended from

2397-444: Was developed in 1999. Certain networks such as Freenode have not followed the overall trend and have more than quadrupled in size during the same period. However, Freenode, which in 2016 had around 90,000 users, has since declined to about 9,300 users. The largest IRC networks have traditionally been grouped as the "Big Four" —a designation for networks that top the statistics. The Big Four networks change periodically, but due to

2448-558: Was the chat part, which he did with borrowed parts written by his friends Jyrki Kuoppala and Jukka Pihl. The first IRC network was running on a single server named tolsun.oulu.fi. Oikarinen found inspiration in a chat system known as Bitnet Relay , which operated on the BITNET . Jyrki Kuoppala pushed Oikarinen to ask Oulu University to free the IRC code so that it also could be run outside of Oulu, and after they finally got it released, Jyrki Kuoppala immediately installed another server. This

2499-570: Was the first "IRC network". Oikarinen got some friends at the Helsinki University of Technology and Tampere University of Technology to start running IRC servers when his number of users increased and other universities soon followed. At this time Oikarinen realized that the rest of the BBS features probably would not fit in his program. Oikarinen contacted people at the University of Denver and Oregon State University . They had their own IRC network running and wanted to connect to

2550-611: Was the one and only IRC network. Around that time IRC was used to report on the 1991 Soviet coup d'état attempt throughout a media blackout . It was previously used in a similar fashion during the Gulf War . Chat logs of these and other events are kept in the ibiblio archive. Another fork effort, the first that made a lasting difference, was initiated by "Wildthang" in the United States in October 1992. (It forked off

2601-499: Was thus based on the Undernet ircd server, although the DALnet pioneers were EFnet abandoners. According to James Ng, the initial DALnet people were "ops in #StarTrek sick from the constant splits/lags/takeovers/etc". DALnet quickly offered global WallOps (IRCop messages that can be seen by users who are +w (/mode NickName +w)), longer nicknames, Q:Lined nicknames (nicknames that cannot be used i.e. ChanServ, IRCop, NickServ, etc.), global K:Lines (ban of one person or an entire domain from
