== Location ==

=== Montréal, Québec, Canada  ===

[http://en.wikipedia.org/wiki/Montreal Montréal] is lively city with English and French widely spoken plus many other minority languages. Most business can be conducted in either language. It has four large universities, two Anglophones, [http://en.wikipedia.org/wiki/McGill_University McGill], [http://en.wikipedia.org/wiki/Concordia_University Concordia]; and two Francophones: [http://en.wikipedia.org/wiki/UQAM Université du Québec à Montréal] (UQAM), and [http://en.wikipedia.org/wiki/Universit%C3%A9_de_Montr%C3%A9al Université de Montréal]. The [http://www.crm.umontreal.ca Centre de Recherches Mathématiques] (CRM) is a mathematical centre that brings together researchers from all four universities and many others from [http://en.wikipedia.org/wiki/Montreal Montréal] and Canada.

The Montréal summer can be quite hot and humid with some chance of rain. The city has a very serviceable public transportation network of buses and underground trains (metro), so it is convenient to get around without renting a car.

=== Venue ===

The CRM will be offering its [http://www.umontreal.ca/ Université de Montréal] facilities for the conference. There is a metro station named after the eponymous university that reaches it.


==== How to get there ====

 Centre de recherches mathématiques
 Université de Montréal
 Pavillon André-Aisenstadt
 2920 Chemin de la tour, room 5357
 Montréal (Québec)
 H3T 1J4

Take your flight to the [http://maps.google.com/maps?f=q&source=s_q&hl=en&q=Montr%C3%A9al-Pierre+Elliott+Trudeau+International+Airport&ie=UTF8&t=m&vpsrc=6&sll=45.764649,-73.100281&sspn=0.747254,1.874542&st=115968771510351694523&rq=1&ev=zo&split=1&hq=Universit%C3%A9+de+Montr%C3%A9al&hnear=&ll=45.461094,-73.748474&spn=0.418036,1.056747&z=11&iwloc=A&cid=2175423857934231437 Montréal-Pierre Elliott Trudeau International Airport].

From the airport, you can either take a cab to any location in the city, which is 40 CAD, or you can take the public 747 express bus, which is 3 CAD. It will take you to the Lionel-Groulx metro station, from which you can continue your travel with the same ticket (it's valid for 2 hours). The metro system is relatively simple to navigate, and [http://stm.info/English/a-somm.htm bus schedules are posted online] and near metro stations.

Starting on Monday, you can get a weekly bus and metro pass for 23.50 CAD. This is highly recommended, as it gives you access to all of the public transportation network within the island of Montréal.

=== Lodging ===

There are several hotels and cheaper lodging in Montréal. Additionally, the universities [http://www.mcgill.ca/students/housing/summer/ McGill University], [http://www.studioshotel.ca/tarifs.php?lang=en&d=h Université de Montréal]) offer dormitory-style lodgings. The CRM also has [http://www.crm.umontreal.ca/coord/hotels_an.shtml more suggestions]. Participiants need to make their own lodging arrangements.

== Dates ==

July 16-20, 2012. First two days are intended for newbies and casual users, who may possibly be interested in getting involved in development. Next three days are for code sprints and development. Participants are encouraged to attend for all five days, but may choose only the first two or last three as convenient.

Some specifics:

=== Monday ===

Introductions, "What is Octave?" talk for a general audience (advertise this a lot in the local scientific computing and engineering communities). Helping with Octave installations, presentations about basic Octave use. 

=== Tuesday ===

More advanced Octave use, including calling Octave from C++ code. Minimum C++ knowledge necessary expounded. How to work with development tools (reading the [http://hg.savannah.gnu.org/hgweb/octave/ Octave source code], using [http://mercurial.selenic.com/wiki/ Mercurial], [https://savannah.gnu.org/bugs/?group=octave bug] and [https://savannah.gnu.org/patch/?group=octave patch trackers], [http://www.gnu.org/software/octave/archive.html mailing lists], [http://www.gnu.org/software/octave/chat.html IRC]).

Social event during evening.

=== Wednesday ===

State-of-the-Octave address. Identify problems to work on, pair off and start working on those problems. Code sprints.

=== Thursday ===

Reports of results of the previous day. Tech talks if necessary. More code sprints.

=== Friday ===

Reports. Last code sprint. Farewells.

== Suggestions for Sessions ==

Code sprints and informal discussion will happen every day. The following are topics of interest for these sessions.

=== Avoiding Maintainer Burnout ===
Or, if we can't find ways to avoid burnout, can we find ways to ensure that no maintainer tasks are the responsibility of a single individual.  That way, there is someone available to handle the task even if a maintainer drops out of sight from the project.

=== Socializing Octave ===
To increase the visibility of GNU/Octave to a wider audience, we could create profiles in several social networks. There are ones based on proprietary software (G+, twitter, facebook) and others free, like [http://en.wikipedia.org/wiki/Identi.ca identi.ca]. We should discuss the perspectives of using them. 
Perhaps we could invite [http://en.wikipedia.org/wiki/User:EvanProdromou Evan Prodromou] to the discussion. He lives in Montreal.

=== Clean up Bugs ===

Code sprint to clean up the [https://savannah.gnu.org/bugs/?group=octave bug tracker]. This would include identifying and closing duplicates, as well as re-qualifying "bugs" that represent feature requests, and closing reports that aren't actually bugs.

=== Cross-platform FLTK Bugs ===

Developers using Linux, MacOS, and Windows cooperate to fix [https://savannah.gnu.org/bugs/index.php?go_report=Apply&group=octave&func=browse&set=custom&msort=0&report_id=100&advsrch=0&status_id=1&resolution_id=0&assigned_to=0&category_id=105&bug_group_id=0&history_search=0&history_field=0&history_event=modified&history_date_dayfd=14&history_date_monthfd=1&history_date_yearfd=2012&chunksz=50&spamscore=5 FLTK bugs]. This represents an important effort toward changing the default graphics toolkit from [http://gnuplot.sourceforge.net/ gnuplot] to [http://www.fltk.org/ FLTK]. See bugs [https://savannah.gnu.org/bugs/index.php?31518 #31518], [https://savannah.gnu.org/bugs/index.php?31976 #31976], [https://savannah.gnu.org/bugs/index.php?32134 #32134], [https://savannah.gnu.org/bugs/index.php?32276 #32276], [https://savannah.gnu.org/bugs/index.php?34720 #34720].

=== Code Sprint for the Wiki ===

Define an effective organizational structure for the new wiki, and clean up the existing content.

* Reorganize existing content to conform the the defined structure.
* Move content to the [http://www.gnu.org/software/octave/ homepage], [http://octave.sourceforge.net/ OctaveForge], or the [http://www.gnu.org/software/octave/doc/interpreter/ documentation].
* Delete spam.

=== Matlab compatibility ===

Comparison of functionality between Octave and Matlab (what is the same, what is close, what is either different or significantly slower).

Here are some major features and classes of functions that are present in core Matlab but not Octave.  Some are currently under development in Octave, but most are not (at least that I know of)

* Classdef classes (handle and value)
* Packages (+dir names in the load path)
* containers.Map class (handle class?)
* InputParser class (to be done correctly requires handle classes)
* MException objects
* cdflib class (handle class?)
* netcdf class (handle class?)
* hdf (4 and 5) functions
* Camera viewpoint functions
* Volume visualization
* Foreign function interface
* Java interface
* COM and Active X
* .NET
* Serial port device functions

=== Profiling ===

Availability and operability of profiling tools for Octave.

=== GUI(s) ===

Availability and operability of GUI interfaces to Octave.

=== 64-bit indexing ===

64-bit indexing for extremely large arrays.

=== Octave and Octave-Forge ===

Discussion of what belongs in Octave Core and what is a package or toolbox. Discussion about minimum functionality for Octave Core.

=== Parallel computing with Octave ===

Tools available, techniques for parallelisation.

=== Octave distribution === 

Making Octave updates trivial for maintenance in large scale computing infrastructures. Octave binary for OS X.  What should be included in an all-in-one installer? What versions of OS-X can/should be "supported"? Octave binary for Windows. What should be included in an all-in-one installer? What versions of Windows can/should be "supported".

We have a good relationship with Debian and Fedora maintainers.  Not so much other GNU/Linux distriubtions.  Can we improve our relationships with others?  How?
