= Sage days 94. Sage development. = The Sage days 94 will take place in Zaragoza (Spain), from June 28th to July 4th 2018, as a satellite activity of the meeting of the spanish network of computer algebra. It will be a series of short courses on subjects related to Sage development. It is mostly oriented to young researchers that want to make the step from writing some code for their own use, to contributing that code to the Sage codebase. == Subjects to cover (provisional) == * The sage development workflow (Trac, git, doctests...) * The coercion model * Implementation of Parents and elements * The category framework * Cython * Using external C/C++ libraries * Communication with external packages using pexpect Besides mini courses on those subjects, there might be some space for short talks contributed by the participants (they can be quite informal).

Since this workshop is focusing in Sage development, it would be better if the participants come with their own laptop, including a Sage install that is well suited for development (don't worry if you can't manage to do so, we can dedicate the first activities of the workshop to help you with that, but it would save time if you do that in advance). Also, please ask in advance for an account in the [[https://trac.sagemath.org/|trac server]] | Given the focus on Sage development, we recommend participants come with their own laptop, including a Sage installation that is well suited for development (don't worry if you have trouble installing, we can help with installation during the workshop, but it would save time if it is done in advance).

Sage days 94 -- Sage development days
Sage days 94 took place in Zaragoza (Spain), from Thursday 28 June 2018 to Wednesday 04 July 2018, as a satellite activity of the 16th meeting of the Spanish computer algebra network (XVI EACA).
They featured a series of short courses on subjects related to Sage development. The main target audience was young researchers who want to take the step from writing code for their own use to contributing their code to the Sage codebase.
Collaborative pad
We used this pad to take notes during the workshop.
For tickets worked on during Sage days 94, we used the keyword "days94":
Mini-course speakers and contributed talks
Topics to cover
- The Sage development workflow (Trac, Git, doctests...)

- The category framework
- Cython
- Using external C/C++ libraries
- Communication with external packages using pexpect
Mini-course speakers
- Samuel Lelièvre

Instructions for participants
Given the focus on Sage development, we recommend participants come with their own laptop, including a Sage installation that is well suited for development (don't worry if you have trouble installing, we can help with installation during the workshop, but it would save time if it is done in advance). Also, please ask in advance for an account for Sage's Trac server.
Lodging
Several apartments were booked in Apartamentos Los Sitios. They are located in the city centre. The reception is open until 22:30.
Location
Talks took place in the main campus of the Universidad de Zaragoza, in the mathematics building. It is about 25 minutes by walk from the apartments (maybe 15 minutes by public transport).
You can see the train station, the apartments and the event location in this map.
Financial support
The school was partly funded by the OpenDreamKit project. The LaBRI (University of Bordeaux) and the CNRS co-organized the project via the OpenDreamKit project. We expect to be able to cover the travel and lodging expenses of most participants and speakers.
