Hybrid Sage Days 120

An inclusive hybrid event on open-source mathematical software

• with the SageMath users and developers around the globe

• co-located with FPSAC 2023, July 17-21, 2023, UC Davis

Sage Days are gatherings of people interested in SageMath, from newcomers to contributors. Sage Days have been organized as local, regional, or international in-person meetings by a wide range of people around the globe, and during the ongoing global health crisis in the form of fully virtual or hybrid events.

About SageMath

SageMath, or Sage for short, is a mature, comprehensive, free (open-source) mathematics software system based on Python, licensed under the GNU General Public License, that integrates computer algebra facilities and general computational packages.

Sage, first released in 2005, in over a decade of incubation in the SageMath distribution, comprising 293 software packages, has grown its own library of over 500 Cython and over 2000 Python modules, ranging from sage.algebras.* over sage.geometry.* to sage.tensor.*, with a total of over 1 million lines of code.

Schedule

Wednesday July 19 13:00-22:00 Pacific Daylight Time (= 20:00 UTC to July 20, 05:00 UTC)

• this is the FPSAC 2023 excursion/free afternoon

• if you're participating in FPSAC, skip the excursions... it's too hot for any of that, do some cool open source instead

Following days: Self-organized coding sprints.
