Sage Days 54: Sage Developer Days

November 4–8, 2013, University of California Davis, USA

The aim of this workshop is for developers to learn the new git workflow, and to try and integrate the combinat queue into git. This workshop will not include beginner topics, but instead assumes participants are familiar with Sage development. We will have an introductory talk on Sage for newcomers on Tuesday afternoon.


Registration is free. There is limited funding for travel and lodging.

Please contact Anne Schilling (anne at math.ucdavis dot edu) or Travis Scrimshaw (tscrim at ucdavis dot edu) to register. Please indicate if you require funding.


The official conference hotel is the Aggie Inn (tel. (530)756-0352). Rates are between 99 and 109 USD depending on bedding type. To get this rate, you need to call the hotel directly and mention the group name SAGE. Last day to book is October 6.

There are other hotels to choose from in Davis, but are generally more expensive.


- From San Francisco Airport (SFO)

- From Oakland Airport

- From Sacramento Airport

All other time will be devoted to coding sprints. We will schedule more talks/tutorials during the week on topics that the participants feel would benefit them.


The general topics that will be addressed at this workshop are the following:

  • Discussion of the new Sage workflow using git.
  • Work on how to integrate the combinat queue into the new workflow.
  • General bug fixes.

Please make sure you have a working Git-version of Sage installed on your computer before you arrive. You can either download a version from Github, for instructions see

For people not yet familiar with Git, we recommend starting from a source distribution. You can find version 5.13.beta1 here

Just download, untar, and run make (like you do with the mercurial based source tarballs).
