VrlWiki

The VrlWiki is a wiki for use by the Brown Visualization Graphics Lab to store project documentation, organizational documents for the group, and information to help researchers in the group work better. Basically, if there's information that ought to be recorded for people to look up, it belongs here. Storing information in a wiki allows anyone in the group to refine it over time, so that it's always up-to-date and as helpful as it can be. If you find an article confusing, misleading, incomplete, or incorrect, please hit the "edit" tab at the top of the page and fix it!

Content

The main page divides the content of the wiki into four groups: group organization documents, documentation for the IT tools that help us do work in the VRL, documentation for projects, and HOWTOs.

VRL

Documents in the "VRL" category include documentation about what our group does at the high level, about our weekly meetings, about the group's and individual members' plans and goals, and so forth.

IT Tools

We have a few different IT tools in place to help us get our work done, including $G and its associated build system and the very wiki you're reading. The wiki entries related to these tools should include technical documentation as well as task-oriented user documentation linked to from the HOWTOs.

Projects

As a research lab our real product is new knowledge. Any given research project may encompass several different software tools, experiments, and publications, in addition to being a general concept unto itself. The documentation for the project should therefore include an overview, notes for the researchers working on it, bibliographies and reading lists, and user and programmer documentation.

Please keep in mind that almost every project lives on beyond the tenure of the researcher who began it. Documentation is crucial to the long-term usefulness of the tools and knowledge you create. This wiki is only visible to our lab and its collaborators, so please be as open about sharing information as you can.

HOWTO

There are a number of tasks that just about every researcher in our group has to do at least once. Choosing a project, writing software and papers, presenting your work, finding a job: all of these tasks are easier with a little guidance. Each HOWTO is an article devoted to a single task and describes in plain language the best way to accomplish it. Keep in mind that the audience for a HOWTO is a complete beginner; the reason someone is reading the article is because they don't know what they're doing.

Security

Access to our wiki is somewhat tightly controlled. We restrict both reading and writing.

Read Permission

Anyone connecting to the wiki from within the Brown network has unfettered read access. Those outside the Brown network will need to use the standard "vrluser" username to log in. Please give out the password only to collaborators, fellow researchers, and relevant students!

Write Permission

Writing to the wiki is restricted to registered users only. Each new account is vetted by dhl and accounts will only be given to authorized individuals. To register or log in, click the "Log in / create account" link in the upper right.

Precautions

Despite our access controls, you can't really be sure who's reading information on this wiki. Per-page access control are hopefully coming in the future, but in the meantime please do not post passwords or sensitive information, especially about human subjects in our research projects, on the wiki.

Special Editing Tricks

Embedding Complex HTML

Only wiki administrators can enable complex HTML, and they do this by creating special embeddable pages. If you have something you'd like to include, please look up a member of the "sysop" group in the wiki user list and ask them to set it up for you. The following are the embeddable pages that already exist.

Google Calendar

Template:gcal adds a Google calendar to the including page. The template looks like this:

{{#shtml:Template:gcal
|src=<a_long_ID_string>
|mode=[AGENDA|WEEK|MONTH]
|height=500
}}

Note that you must include values for each argument. Figure out the values by the following procedure:

1. Open up Google calendar.
2. Select the drop-down menu for the calendar you want and select "Calendar settings".
3. Scroll down to "Embed This Calendar".
   • You may also want to click the "customize" link to get other options.
4. In the text box containing the embed code, look for a string like http://www.google.com/calendar/embed?<key_1>=<val_1>&amp;<key_2>=<val_2>...
5. For each of the arguments above, look for the corresponding key in the embed code and set the argument to the corresponding value.
   • src will be a long string, probably ending with "group.calendar.google.com".
   • mode is one of AGENDA, WEEK, or MONTH.
   • height is 500 by convention on our wiki but you may choose any height in pixels.
