## Introduction to Zephyr
-Zephyr was a system designed to let system administrators send
-important messages to users in an easily noticeable format. It was
-meant to have a low volume of traffic and be used only for official
-notices. This is obviously not what Zephyr is today. It can still be
-used in the way it was intended: notice that you get official
-zephyrgrams as you log in, with important information about Athena
-services and planned outages. However, the most common usage is by
-average users exchanging information about classes, how their days are
-going, and talking on Zephyr classes and instances about everything
-from the latest episode of Battlestar Galactica to the next 18.03
-problem set. The usage of Zephyr has far exceeded original
-expectations. Over time, people have also created programs that give
-Zephyr a graphical interface, and programs that give zephyr a purely
-textual interface, that can be used entirely within a ssh
-terminal. Some of these zephyr clients have become so widely used that
-there are users who do not know that there are other ways to send (and
-receive) zephyrgrams. This wiki will cover the traditional commands,
-typed at the athena% prompt, as well as the more common modern zephyr
-client Barnowl.
-
-The information in this wiki about Barnowl just barely touches the
-surface. More for in-depth functionality, visit the [Barnowl
-wiki](https://barnowl.scripts.mit.edu:444/wiki).
-
-## Modern Zephyr
-
-Today the majority of Zephyr users use the barnowl client. There are
-other clients as well (for example, Pidgin supports Zephyr). The
-following sections will go into detail about how to install, use, and
-customize barnowl.
-
-### Other Clients
-
-There are other clients besides Barnowl, however their use is not
-nearly as widespread. Some of these include:
+Zephyr is a general purpose chat system for MIT.
-* Owl (unmaintained, Barnowl evolved from this)
-* vt / jervt
-* zwgc (see TraditionalZephyr)
-* Pidgin
-* zephyr-mode for emacs
+People use it to exchange information about classes, how their days are
+going, and talk on Zephyr classes and instances about everything
+from the latest episode of Game of Thrones to the next 18.03
+problem set.
+
+Zephyr is an underlying chat system; the built-in tools for exchanging messages via Zephyr are rudimentary. Most people who use Zephyr today take advantage of integrated clients that make the system easy to use.
+
+## Major clients
-Using Barnowl is recommended, as it is better supported and more
-documentation exists for it.
+Here are some of the primary clients used at MIT. There's also a listing of [other Zephyr clients](http://zephyr.1ts.org/wiki/ZephyrClients), but their use is generally not recommended.
-### Using Barnowl
+### BarnOwl
-To start barnowl, run the command `add barnowl; barnowl` at the prompt
-on any Athena machine or dialup, such as linerva.mit.edu.
+[BarnOwl](http://barnowl.mit.edu/) is a command-line Zephyr client that supports advanced filtering and customisation. It is probably the most commonly used client, but requires some effort to get started. To use BarnOwl effectively, you should connect to an [Athena dialup](http://web.mit.edu/dialup/www/ssh.html) and run BarnOwl along with a program to renew your Kerberos tickets. The Athena command `athrun sipb owl-screen` will set this up for you.
-The simplest use of Zephyr is to send personal zephyrs to other
-users. To send a zephyr, type `:` to bring up a command line, and run
-the command `zwrite USERNAME`. You can also start a `zwrite` command
-by simply typing z.
+In addition to primarily supporting Zephyr, BarnOwl also lets you connect to [AIM](http://aim.com) and and [XMPP](http://xmpp.org/) (Google Talk, Facebook, etc.) networks.
-You can then enter your message, and then enter a `.` on a line by
-itself to finish the zephyr. By convention, zephyrs are usually
-word-wrapped to 70-character lines or so; Pressing M-q (Alt-q, or
-Escape then q) will word-wrap the text you've entered for you.
+See [Getting Started with BarnOwl](http://barnowl.mit.edu/wiki/GettingStarted) for more information.
-Once you've sent and received zephyrs, you can navigate the message
-list with the arrow keys. Press `d` to mark a message as deleted, `u`
-to undelete it, and `x` to expunge all messages that have been marked
-as deleted.
+### Roost
-Instead of entering a `zwrite` command manually, you can also select a
-message in the message list with the arrow keys, and reply to it using
-`r`, which will automatically set up an appropriate `zwrite` command.
+[Roost](https://roost.mit.edu/) is a graphical Zephyr client built by [David Benjamin](https://davidben.net/) (MIT '12, SIPB member) as part of his [master's thesis](https://davidben.net/thesis.pdf). It is relatively new and currently considered experimental by its author.
-For more documentation on the built-in commands and keybindings, you
-can press h to bring up barnowl's built-in help screen. For help with
-a specific command, bring up a command line with `:` and then type
-`help COMMAND`.
+Roost makes use of [Webathena](https://webathena.mit.edu/) to keep you subscribed to Zephyr. This makes for a much easier setup.
+
+### Zulip
+
+
+[Zulip](https://zulip.com/zephyr) is a web-based Zephyr client that also provides [mobile apps](https://zephyr.zulip.com/apps) for Android and iOS and desktop apps for Linux, Mac, and Windows. Zulip is developed by a company composed largely of MIT alums and SIPB members.
+Zulip, like Roost, is easy to set up because it uses Webathena for authentication.
+
+See [Zulip for MIT setup](http://zulip.com/zephyr) for details.

+## Culture
### Classes and Instances
-Generally the most interesting discussion on Zephyr, however, happens
+Generally the most interesting discussion on Zephyr happens
on so-called Zephyr <em>classes</em>. A class is a bit like a chat
room in other IM systems. Anyone can send a zephyr to a class, and
anyone who is subscribed to that class will receive it. There is no
To subscribe to a class, use the subscribe command:
- :subscribe CLASSNAME * *
+ :subscribe CLASSNAME * *
To send a zephyr to a class, use the zwrite command with the -c option:
> report what one is working on or up to, or ask friends questions, or
> just rant about something.
-<strong>"un" Classes</strong>:
-> Many people use "un" classes in addition to their personal class,
-> for example `johndoe` might use `-c unjohndoe`. Sometimes there are
-> nested un-classes as well, such as `-c ununjohndoe` or `-c
-> unununjohndoe`. It is extremely rare to see anything more than
-> three "un"s. Un-classes are generally used for snarking about a
-> conversation going on in the next class up (`-c unjohndoe` snarking
-> about `-c johndoe`), or for more intense ranting. The more "un"s,
-> the more intense the snarking/ranting generally becomes.
-
### Zephyr Slang
If you spend enough time on Zephyr, you'll begin noticing some strange
means, try using the `whats foo` command at an Athena terminal. If you
don't have the command, run `add sipb` first.
-### Startup
-
-There might be some options that you want to be consistent from
-session to session; you don't want to have to set the same variables
-each time. You can fix this by adding the commands to your "startup"
-file, for example, `.owl/startup`. This can be done from within
-Barnowl, by using the `startup` command:
-
- :startup set foo bar
-
-Where `foo` is the variable you want to set, and `bar` is the value.
-You do not necessarily have to use the `set` command, either, any
-command you can type in Barnowl can be added to the startup file.
-
-### Logging
-
-It is handy to be able to log your conversations so you can refer back
-to them later. To log classes, for example:
-
- :set classlogging on
-
-And to log personals:
-
- :set logging on
-
-This will log to the "zlog" directory in your locker. You probably
-don't want people to see what classes you're on or what people you
-talk to, so you can run the Athena command
-
- mkdir -p ~/zlog
- fs sa ~/zlog system:anyuser none
-
-to make this directory completely hidden.
-
-### Colors
-
-By default, there are seven colors you may use in the terminal: red,
-green, yellow, blue, magenta, cyan, and white. In order to use color
-in Zephyr, you can use the following notation: `@(@color(red)This is
-some red text))`
-
-Colors may vary from machine to machine, as different terminal
-profiles may have different shades of the seven colors.
-
-### Filters
-
-Some people like to customize their Barnowl by color-coding classes.
-This makes it easier to tell different classes apart (and minimize
-mixing). Barnowl has some already existing filters, for example,
-`personal` (for incoming personals), `out` (for outgoing personals),
-and `ping` (for pings). To assign a color to a filter, add the
-following to your startup file:
-
- filter personal -c green
-
-What if you want to color-code your class, or a friends class? You
-can create and color filters with:
-
- filter johndoe class johndoe
- filter johndoe -c blue
-
-You can update your settings and filters without restarting your
-Barnowl session by:
-
- :source ~/path/to/config/file
-
-You can see all the filters by using `:show filters`, and narrow to a
-particular filter with, e.g., `:view personal`. You can use `:view
-all` or the keyboard shortcut `V` to see all messages again.
-

-https://barnowl.scripts.mit.edu:444/wiki/Filters.
-
-## Running Barnowl in Screen
-
-It can be very annoying to have to close Barnowl when you turn off
-your computer. During the time your computer is off, you're missing
-many (possibly important) zephyrs. It can be aggravating to be using
-zephyr via an unreliable network connection. It can also be
-frustrating if you leave your computer on with Zephyr up, but go to a
-different computer and want to check your zephyrs - how do you do
-this? These problems can be solved with the magic of screen.
-
-A more detailed and extensive explanation of this can be found at
-http://web.mit.edu/kchen/bin/owl-screen.txt.
-
-### Screen
-
-You should find a computer or server on which to run your screen
-session(s) that is up all the time, for example, linerva.mit.edu.
-Screen allows you to run programs inside of it on one computer, and to
-access those same programs from other computers via ssh.
-
-### Quickstart
-
-1. Pick a machine to host your screen session on.
- If you don't know of any options, linux.mit.edu (Linerva) is a good choice.
-2. ssh to that machine.
-3. Run "add kchen". You may want to add this to your `~/.environment` file.
-4. Run "owl-screen"
+### Zephyr Etiquette
-Your screen session is now ready. Once you start the screen session,
-you'll need to get renewable Kerberos tickets in order to run it for
-any extended period of time. Press C-a C-c to open a new screen
-window, and run
+There are rules that people tend to use on Zephyr. These include:
- kinit -l7d -54
+Good grammar, spelling, and punctuation. Not everybody uses
+capitalization, but they will still use good English. Please do not say
+things such as "hey wut r u up to???". It makes you look like an idiot.
+Really.
-(length 7 days, both Kerberos 5 and Kerberos 4). Press C-a 0 to return
-back to your Barnowl window.
+You don't need multiple question marks or exclamation points. Usually.
-When you're ready to log out, press C-a d to "detach" your screen, and
-then type `exit` or `logout` to log out. Later, when you want to
-"reattach" your screen, ssh to the machine again, and run `screen -r`.
+There are a few abbreviations people use, such as YMMV (Your Mileage May
+Vary) or IIRC (If I Remember Correctly), as well as some nerdier ones
+like DTRT (Do The Right Thing, in reference to
+[ The Rise of "Worse Is
+Better"](http://www.jwz.org/doc/worse-is-better.html)). Try running `add sipb; whats dtrt` to look up an
+abbreviation. Common abbreviations that you might find on AIM, however,
+are not often used. People tend to look down upon "lol", "rofl", and
+such.
-### Kerberos Tickets and AFS Tokens
+Personal classes are by convention considered a little more private than
+non-personal (public) classes. Although most people don't mind people
+they've met subscribing to their personal class and lurking, it's poor
+form to talk loudly on the personal class of someone you don't know.
-In order to keep your screen session authenticated, you'll need to
-keep your Kerberos tickets and AFS tokens up-to-date. There is a
-script that will do this for you, located in the `kchen` locker.
-After you ssh into the machine that hosts your screen sessions, run
-the following commands:
- add kchen
- owl-screen
- C-a C-c
- kinit -l1d -r7d -54
+## Interaction with Traditional Zephyr
-### Attaching and Detaching Sessions
+The default Athena startup scripts launch `zwgc` on login. `zwgc` displays a popup for each message, so if you are subscribed to many classes and use Zephyr as many do today, `zwgc`'s behavior is not very desirable. To disable `zwgc` startup, add:
-To detach a screen session (for example, if you want to log out),
-press C-a d (Control-A, then D). Screen continues to run, but is no
-longer active.
+ setenv ZEPHYR_CLIENT false
-To reattach a screen session, possibly detaching from wherever it's
-currently attached, run:
+to your `~/.environment` file if you use `tcsh` or
- screen -dr
+ ZEPHYR_CLIENT=false
-`screen` can do a whole lot more. To find out about it, see
-[UsingScreen](https://sipb-www.scripts.mit.edu:444/doc/wiki/UsingScreen).
+to your `~/.bash_environment` if you use `bash`. This will cause your
+shell to launch the `false` executable instead of `zwgc` which does
+nothing.
