Dave Hay
Blog Title A Portal to a Portal
Blog Description Geeking in technology since 1985, with IBM Development, focused upon Docker and Kubernetes on the IBM Z LinuxONE platform In the words of Dr Cathy Ryan, "If you don't write it down, it never happened". To paraphrase one of my clients, "Every day is a school day". I do, I learn, I share. The postings on this site are my own and don’t necessarily represent IBM’s positions, strategies or opinions. Remember, YMMV
