William Stucke

William was educated in 17 places in 3 continents, eventually getting some weird non-specific Honours Engineering degree in London.

That's just as well, because he was a Construction, Project, Electrical, Mechanical, Systems and Control & Instrumentation Engineer and that's just in the Mining Industry.

After that, he wandered back to the Telecoms Industry and became a bit of a pain about telecoms liberalisation in Africa. Along the way, he co-founded ISOC-ZA, AfrISPA and NameSpace, and led all of them at some stage. He also made noises at ISPA, who were so glad he left that they gave him an award.

He programmed his first huge mainframe (with 36 K of hand-built Ferrite Core Memory) in 1972, built the first fibre optic network in an underground mine in 1988, started his first ISP in 1996 and did a bunch of clever stuff no one else had thought of, with lots of help from his partners, until they bailed. For his sins, he ended up being an ICASA Councillor and is now a Consultant, flogging his enormous skills (and tiny ego) on the open market.

Una Karlsen

Over a 20-year IT career, Una has worked for several small ISPs, building
and managing Network, VOIP and Billing infrastructure, starting in 2000 and
ending with a large Cloud provider in 2019. In between, she has done
security audits, software development, product development and customer
support. Currently unemployed after a long bout with chronic illness, Una
is in the process of starting a nonprofit to provide services to
underserved communities.

Being a FLOSS, Linux, Security, and DevOps enthusiast, passing on knowledge
has always been part of her DNA. Be it through local user groups or
training staff. A vocal advocate for IPv6 adoption since 2000, Una believes
in building things right and building them to last. This also means
building them to be fault tolerant, and where possible self healing.

Una believes in transparent governance and thinking global while acting


local. In practice this means working on solutions that fit local
situations best, learning from the experiences of others from abroad and
sharing her learnings so that results can be replicated elsewhere.
