My name is Mark Himsley. Thank you for your interest in mdsh.com.

I work for the British Broadcasting Corporation in London UK. I started at the BBC in 1986 where I was trained in broadcast Technical Operations, specialising in Video Editing and Film transmission.

My current roll at the BBC is as a Senior Architect, embedded in two software development teams who design and develop internal software and systems used across BBC News and other BBC short-form video editing areas.

Following my original training I have become a domain expert in broadcast video media, and I am a local domain expert in the use of FFmpeg in a broadcast environment, with code I have created and fixed being included in FFmpeg.

Through my BBC career I have been:
a Technical Operator recording and playing packages and programmes to air
a Studio Manager mixing live and recorded radio packages
a Dubbing Mixer of some News TV programmes
a Video Editor using Media Composer, Final Cut Pro, and Quantel sQEdit
a Software Developer writing Java, Python, Perl, SQL, and C

When I wasn't working for the BBC between 1997 and 2001 I helped create a couple of startup Internet Service Provider companies, where I built and maintained the networks and servers; managed the hosting and databases; and wrote software in C, Perl and ColdFusion. The companies built and hosted web sites and offered other Internet services from our own facilities in Fulham, London; and from hosting facilities in Docklands, London.

When I'm not working you'll often find me maintaining my home-lab, consisting of VM platforms, Raspberry Pis, and Kubernetes clusters, which run GNU/Linux servers which serve several web sites, including this one, and serve my email, DNS and all other associated Internet services. They also provide DHCP, DNS, SMTP, IMAP, XMPP and other services, and IPv4 and IPv6 connectivity to my home network. I also do video editing and sound mixing at home on my non-linear edit systems and digital sound mixing systems.
