Damn. Hans was the primary person responsible for Infiniband in FreeBSD, and also the Mellanox ethernet drivers that made their way into FreeNAS/TrueNAS.<p>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.<p>The xhci stack he implemented was also a notable contribution I remember using early on.<p>I was always impressed by how much he could do and do well.<p>I am quite saddened by the lifetime that was stolen away from him and his family.
RIP Hans.<p>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.<p>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.<p>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.
