In his spare time, he is also a ham radio operator and runs his own ISP powered by OpenBSD routers.

Pierre Pronchery is passionate about Open Source software and Operating System internals in particular, which has led him to join the NetBSD Foundation as Developer in 2012 and then as Director on the Board since 2017. Learning how systems work also teaches how they break, and it only made sense for him to advise and audit major companies professionally as IT-Security Consultant, in a variety of situations involving Penetration-Testing, Incident Response, Reverse Engineering, or Red Teaming. More recently, he joined the FreeBSD Foundation as Security Engineer, where he currently helps the FreeBSD Project as Developer and member of the Security Team.

My first experiences with version control were with CVS in ca. 2004.

I became a contributor to the Subversion project in 2007, before the project was moved under the Apache umbrella. I ended up co-developing several major features for Subversion, such as the redesigned working copy format of SVN 1.7, the 'svn patch' command, and an improved merge conflict resolution system in SVN 1.10 and later which can track file renames through merges.

I spent more than a decade consulting and running workshops for European companies and organizations using Subversion and, when its adoption started to increase, Git. I am still supporting the Subversion project and its users today, though in a smaller capacity.

In 2017, with encouragement and help from friends in the OpenBSD community as well as the Subversion and Git project communities, I started writing a new tool from scratch based on the Git repository format design, which became the Game of Trees project.

I am Varinka Ohanyan, a system administrator at the Armenian Bioinformatics Institute in Yerevan, where I maintain an all-FreeBSD-based-but-actually-Linux HPC cluster for genomic research. I manage Star Wars-themed servers running bhyve virtual machines for compute and FreeBSD jails for infrastructure services - including LDAP, DNS, web hosting, wikis, ticketing, and a few other prisoners. My days are spent keeping Slurm-scheduled nodes healthy for scientists, maintaining ZFS storage and backups with zelta, and helping researchers with whatever problems they create for themselves. I document things on our internal but public wiki and aspire to one day become a competent porter. Other than that, I study bad engineering at the American University of Armenia and am awful at math.
