Just wanna say what a well-written eulogy that was.

Damn. Hans was the primary person responsible for Infiniband in FreeBSD, and also the Mellanox ethernet drivers that made their way into FreeNAS/TrueNAS.

A Good guy, he'll be missed. :(

That's very sad. Remember seeing that last name Selasky in the kernel source code. I definitely appreciated his ISDN support 25 years ago in FreeBSD - a life saver. And all the other amazing contributions. What a loss.

I remember him answering my questions about some intel i915 Xorg issues when I was running FreeBSD on my first notebook when I was a teenager.

The xhci stack he implemented was also a notable contribution I remember using early on.

I was always impressed by how much he could do and do well.

I am quite saddened by the lifetime that was stolen away from him and his family.

RIP Hans.

I have used his ISDN stack thoroughly, implementing call-logging with a client for workstations linking the call directly to a CRM and voicemail. I remember him starting his alternative(?) USB stack. I also contributed an addition to an existing driver importing a hand full of Linux drivers for small peripheral I2C chips. In hindsight this path must have been inspired by his previous work.

Super sad to see him go this young, and it amazes me to realize how young he was when he was contributing all this heavy lifting already.

Giants ...

I remember Hans from his work to integrate the Video4Linux libraries into FreeBSD. He was a very gentle person I enjoyed to work with. I will miss him.
