GeoServer Code Sprint 2016

2015-12-21T21:58:56Z

Bencaradocdavies: /* How to Sponsor */

== Purpose ==

The GeoServer web administration console is built on top of the [https://wicket.apache.org/ Wicket] 1.4.x series,
which is pretty old and unmaintaned. The purpose of the sprint is to update it to Wicket 7.x, the current stable version.

[[File:Wicket-upgrade.png|center|Upgrade from Wicket 1.3 to Wicket 7]]

Due to the large distance between the two releases and the number of backwards incompatible changes accumulated
by Wicket in the years this will require the concerted effort of a handful of developers over a few days, including the
changes to upgrade the code, and the thorough hand testing of the resulting modified interface.

We would like to extend our thanks to the following sponsors:

Gold Sponsors:

Silver Sponsors:

Bronze Sponsors:

=== Organizers ===

* Jody Garnett - Boundless
* Andrea Aime - GeoSolutions

=== Venue and dates ===

The code sprint will be held in Victoria BC to minimize travel costs. Boundless has offered to provide a venue (either the Boundless Victoria offices or a local technology centre).

The date is tentatively set for the week of January 18th.

This date is selected towards of the GeoServer 2.9 release cycle prior to the code freeze in February, keeping resource availability in mind.

=== Accommodation and costs ===

Participants should plan the travel, accommodation and meals.

* Depending on sponsorship level guests to Victoria will be hosted at or billeted with local community.
* At the time of writing accommodation for four guests is available (thanks to Jody Garnett and Martin Davis).

We hope to raise enough financial support to cover overseas travel, and possibly meals.

=== Sponsorship ===

We have the following sponsorship levels:

{| class="wikitable"
|-
| Gold
| style="text-align:right;" | $1000 CAD
| style="text-align:right;" | $740 USD
| style="text-align:right;" | €548 EUR

| style="text-align:right;" | $185 USD
| style="text-align:right;" | €137 EUR
|-
| Beer || colspan="3" | In-kind contributions are graciously accepted
|}

Contributions will be put towards travel costs for overseas sprinters who would be otherwise unable to attend. Any surplus at the end of the event will be turned over to OSGeo or used for a future code sprint. We have set-up the sprint to minimize travel and accommodation costs.

Sponsors will receive the following honors:

* Your logo at the top of this page
* Mention in all of our public communication, including GeoServer 2.9 release announcement
* Our gratitude :)

For more information on sponsorship, please contact [[Jody Garnett]], [[User:Aaime|Andrea Amie]] or the OSGeo [[Treasurer]].

==== How to Sponsor ====

# Navigate to the [http://www.osgeo.org/ OSGeo website]
# Click on the "Donate" button in the top right corner
# Donations are handled through PayPal, when making the donation be sure to:
#* Check the currency (USD rates are provided above)
#* Use the "Add special instructions to the seller" field on the confirmation page to mention the event (example "GeoServer code sprint sponsorship")
#* To make alternative arrangements contact OSGeo [[Treasurer]]
# The OSGeo [[Treasurer]] will contact both you and the event organizers to acknowledge your sponsorship
#* Please have a logo ready for your organization if you wish to be acknowledged publicly
#* Your event sponsorship, at your request, can contribute towards [http://www.osgeo.org/sponsorship being recognized] as an OSGeo sponsor

==== Sponsorship Outreach ====

We are reaching out to organizations to see if there is interest in sponsorship:

* International organizations (OSGeo, Boundless, GeoSolutions);
* Local organizations (BC Government, Refractions, Vivid Solutions)

If there is a lot of local sponsorship we expect to drag the developers away from the task at hand and meet the local community (at a social evening or similar).

==== OSGeo Funding Request ====

The following information is requested by OSGeo Board [[Code_Sprint_Guidelines]]:

== Code Sprint - what's that? ==

A code sprint is usually organized by a group that is using an open source project and wants to see something done. They fly the developers to a single location and feed them for a couple of days with the necessities of the hacking life (internet, caffeine, electricity). The communication that happens from face to face hacking usually lasts the project for a year or more. You see this a lot in projects like Drupal etc...

Live GIS GSoC 2014

2014-04-28T03:04:23Z

Bencaradocdavies: /* Mentors */

= OSGeo-Live Google Summer of Code ideas 2014 =

==About==
OSGeo-Live is a self-contained bootable DVD, USB thumb drive or Virtual Machine based on Xubuntu, that enables new users to try a wide variety of open source geospatial software without installing anything.

Ideally we like OSGeoLive projects to be installed from UbuntuGIS .deb files, as this enables the applications to be available and easily installable on Ubuntu distributions. However, to date (in 2014), only about half the applications are bundled as .deb files. In particular, most of the java based projects have not been bundled as .deb files.

==.deb packaging of OSGeo projects ==

The idea for this project is to take as many projects as possible through the process of bundling into .deb files, with a particular emphasis on solving java based projects. Ideally, the generation of the .deb files will be incorporated into the project's build process, and the .deb files will also be included into main Debian by the help of Debian GIS team (which ensures automatic migration to UbuntuGIS).

This project will be a challenge for anyone game to take it on, requiring a combination of research to identify and overcome existing stumbling blocks, researching of best practices in packaging, .deb packaging, liaising with projects, likely updating java software, creating install and build scripts (probably in bash shell), and probably a few more things as well.

The hurdles that have previously been limiting factors include:
* Most java projects have previously been built from Sun/Oracle version of Java, which could not be included in debian/ubuntu due to licence restrictions.
* The OpenJDK version of Java, which is bundled with Debian/Ubuntu historically had limitations, which seem to have been completely (or at least mostly) resolved. (The last version of OSGeo-Live was built with OpenJDK instead of Sun Java.
* There is a knowledge gap between Java communities and Debian packaging communities, with a lot of experience in each group, but very few who understand the requirements, processes and tools of both. To address this, we have mentors from each community to support the student.
* Some of the optional libraries (such as JAI) used within the java communities have licensing restrictions which have been incompatible with Debian packaging. Dependencies need to be understood and the alternative libraries/options put in place.

Theoretically, all these stumbling blocks can be resolved, which will be the challenge for the student taking on this task.

Besides creating Debian packages of new software some metapackages featuring the osgeolive packages should be created using the [http://blends.debian.org/blends/ Debian Blends framework].
