= Global Virtual SageDays 109 = an event for the SageMath user and developer community on the occasion of the [[https://wiki.sagemath.org/ReleaseTours/sage-9.1|release of SageMath 9.1]] held on '''Thursday, May 28, 2020''' (when it is that date in [[https://en.wikipedia.org/wiki/List_of_UTC_time_offsets|some timezone in the world]]) * '''Beginning: Wednesday, May 27, 2020, 10:00:00 (morning) GMT''', .... which is May 28, 2020, 00:00 Kiribati time (UTC+14), * '''End: Friday, May 29, 2020, 11:59:59 (noon) GMT''', .... which is May 28, 2020, 23:59:59 Baker Island time (UTC-12), a '''50-hour fully virtual event.''' [[https://researchseminars.org/seminar/SageDays109|Schedule, videos, and materials at researchseminars.org]] [[https://wiki.sagemath.org/Workshops|SageDays]] 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. Because of the current global health crisis, we organize SageDays 109 as the first fully virtual event in the series. <> == About SageMath == [[https://www.sagemath.org/|Sage]] 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 [[https://github.com/sagemath/sage/tree/develop/build/pkgs|SageMath distribution, comprising 293 software packages]], has grown its own [[https://github.com/sagemath/sage/tree/develop/src/sage|library of 1000 Cython and over 4400 Python modules]], ranging from `sage.algebras.*` over `sage.geometry.*` to `sage.tensor.*`, with a total of over 2.2 million lines of code. [[https://wiki.sagemath.org/ReleaseTours/sage-9.0|SageMath 9.0]], released in January 2020, completed the transition of the Sage library to Python 3. == How to participate == * '''Please register (ASAP) if you intend to participate''': https://zulip.sagemath.org/#narrow/stream/126-sd109/topic/Registration.20for.20Global.20Virtual.20SageDays.20109 * Join our [[https://zulip.sagemath.org/#narrow/stream/126-sd109|zulip #sd109]] messaging stream. This stream drives the SageDays event. All activities are announced there. * '''Video conferencing'''. We will mainly be using a free (open source) software solution for videoconferencing: Discussions and talks will happen via [[https://bigbluebutton.org/|BigBlueButton]] (BBB; see [[https://en.wikipedia.org/wiki/BigBlueButton|Wikipedia page]]; [[https://bigbluebutton.org/open-source-license/|license]]). We will use the BBB servers at Orsay and/or other French institutions. For the convenience of presenters, we may also use Zoom or Google Meet. * Details, schedule, how to access: will be announced on the Zulip stream. == Activities == [[https://researchseminars.org/seminar/SageDays109|Schedule at researchseminars.org]] * '''Update: Videos and materials available''' To offer or request additional presentations on specific topics, please edit https://trac.sagemath.org/wiki/SagePresentationsMarketplace and/or post a message in the zulip stream #sd109. === Confirmed Speakers === * [[http://alexjbest.github.io/|Alex J.
