YafaRay Code Sprint 2012

This year we are going to organise a code sprint for developers of the YafaRay project. The main purpose is to motivate and support a new generation of developers who are doing a great work on YafaRay and the exporters, and at the same time to keep past developers on the loop.

The event will take place in Madrid on 22, 23, 24 and 25 November 2012. We will use our project funds and donations to help developers with travel and accomodation expenses. If you would like to attend please contact us at alvarolunab(at)yahoo(dot)es

The event is open to any developer, he/she does not need to show previous contributions to the project, only sufficient skills. However, it is not a holidays trip. Every attender should work during the scheduled time for coding on a planed list of tasks. These tasks should preferably be active bugs from the bugtracker or improvements on existing tools. Developers should have their own list arranged and coordinated with the Sprint Master before the event. People are also welcome to give brief lectures to the other developers, for instance about YafaRay architecture or new developments. These lectures will happen early in the morning before the coding sessions start and should not last longer than 1 hour. These lectures might be recorded if we get equipment to do so.

What is a code sprint?

A sprint is a get-together of developers to give a focused development on a project. These events are typically two to seven days long. Sprints have become popular events among some Open Source projects.

These get-together are organized around the ideas of the Extreme Programming discipline of software development. The sprint is directed by a coach, who suggests tasks, tracks their progress and makes sure that no one is stuck. Most of the development happens in pairs. A classroom or a conference room is often chosen as a venue for efficient communication. A significant benefit of sprinting is that the project members meet in person, socialize, and start to communicate more effectively than when working together remotely.

At the moment we are looking for premises at an university or public library in Europe, particularly in Spain, to host the coding sessions. Attendance will be between 5 and 10 developers and the event will run for at least two days. If you would like to help us with this matter, please contact us at alvarolunab(at)yahoo(dot)es


The budget for the code sprint is aproximately €4000. About 2/3 of that money will be used for air travel expenses as we expect 1 or 2 people to come from the other side of the Atlantic Ocean. Our target is to raise at least one half from donations and sales of educative items. The other half will come from our reserves, but the more we raise from donations and sales the better.

Legal framework

YafaRay donations are handled by a legal entity called SPI (SOFTWARE IN THE PUBLIC INTEREST INC). SPI is an non-profit umbrella organization which was founded to help projects develop and distribute free open source software and hardware. SPI sponsors renowned projects like Debian, LibreOffice.org, PostgreSQL and others:


YafaRay funds must be used as per non-profit organisation's rules and practices. Apart from the monthly report made by the SPI board, the Yafaray team will report to the Community about how much money is collected and how it is expent.

Tax Information

The Internal Revenue Service (IRS) of the United States government determined that under section 501 (a) of the Internal Revenue Code, SPI qualifies for 501 (c) (3) (non-profit organization) status under section 509 (a) (1) and 170 (b) (1) (A) (vi). This means that all donations made to SPI and its associated projects (such as YafaRay), should be tax deductible for donors in the United States of America. People or businesses should consult their tax advisor for further information on this regard.
