With approximately 350 people in attendance, we kept pace with last year—with a few improvements. In particular, our tech team did a fantastic job improving our video feeds, with peak usage at around 300 simultaneous views. We also worked hard to streamline the registration process, reducing time spent waiting in the registration line before Richard Stallman's Saturday morning keynote, with few hiccups.

Morning registration at LibrePlanet

Let's take a look at some more highlights.

Read our post about day one of the conference and the election of our newest board member, Kat Walsh.

FSF board member Benjamin Mako Hill kicked off Sunday morning with an examination of how the free software community has progressed with two major goals: access and empowerment. He argued that empowerment has a long way to go, and offered some suggestions for next steps.

This year, we had over 40 speakers, and like last year, about 40% were women.

Karen Sandler, in her new role as executive director of the Software Freedom Conservancy, gave her third LibrePlanet keynote to close the conference, expanding on the recent suit brought by Christoph Hellwig, contributor to the kernel Linux, against VMWare for violating the GPL by not releasing the source code for the version of the operating system kernel they distribute with their ESXi software. Read our statement of support here.

Sunday's talks explored the possibilities for free software: Jennie Rose Halperin of Safari looked at free software's potential role in cultural heritage organizations, Brett Smith discussed Arvados, a free software platform for big data science, Free Software Award-winner Sébastien Jodogne gave one of several talks on free software's role in medicine, and other talks looked at free software possibilities for universities and journalism, as well as examining threats to free software, gathering the community for strategy sessions, and offering practical training.

Our sustained partnership with MIT's Student Information Processing Board once again helped make LibrePlanet great, thanks to the energy and enthusiasm of SIPB's membership.

We on the FSF staff owe many thanks to our tireless volunteers, without whom LibrePlanet couldn't possibly be as large or well-run as it is.
