The FreeBSD community was saddened this month by the tragic death of one of its most prolific contributors. We learned that Hans Petter Selasky passed away in a traffic accident in Lillesand, Norway on June 23, 2023 at the age of 41. Hans was an incredibly brilliant and kind person, and made many valuable contributions to FreeBSD. He was preceded in death by his father Gordon, and is survived by his mother, Inger Elisabeth, his brothers Mark and Leif Conrad, and his nieces and nephews Petra, David and Signe.

Hans began contributing to FreeBSD roughly 25 years ago, with fixes to FreeBSD’s ISDN support. He was a FreeBSD committer for nearly 15 years, and was best known for re-writing and maintaining the USB stack. Hans wrote the webcamd package which supports running Linux webcam drivers in userspace on FreeBSD, and which enables those of us using FreeBSD on the desktop to participate in modern teleconferencing. Most recently, he worked for Mellanox (now Nvidia) to support their ConnectX series of high speed NICs on FreeBSD. Hans’s work included major contributions to the kernel TLS framework, as well as support for NIC kTLS send and receive offload in the mce(4) driver, and many improvements to the Linux device driver compatibility
layer.
