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

I am now retired. Before I retired I worked for the British Broadcasting Corporation in London UK. I started working at the BBC in 1986 where I was trained in broadcast Technical Operations, specialising in Video Editing and Film transmission.

My final role at the BBC was 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 became a domain expert in broadcast video media, and a local domain expert in the use of FFmpeg in a broadcast environment, with code I created and fixed being included in FFmpeg.

Through my BBC career I was:

• a Technical Operator: recording and replaying packages and programmes live to air
• a Studio Manager: mixing the audio of live and pre-recorded radio packages
• a Dubbing Mixer: mixing the audio of edited films for transmission in some current affairs programmes
• a Video Editor: creating packages and programmes for transmission using Avid Media Composer, Apple Final Cut Pro, and Quantel sQEdit
• a Software Developer: writing software in 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.

These days you'll often find me maintaining my home-lab, consisting of VM platforms, Raspberry Pis, and Kubernetes clusters. They all run GNU/Linux and host services 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 VLANs. I also do video editing and sound mixing at home on my non-linear edit systems and digital sound mixing systems.
