After 40+ years at IBM and 25+ year in MQ, I'll be retiring on June 5th 2018.
Instead of a sudden end, I intend to wind down, and so Ive set up a non IBM blog where I can add things of interest once I do retire. I have email address firstname.lastname@example.org. If you have questions I may be able to answer them. One colleague who retired, said that three months after he retired, he could not remember how to logon to z/OS.
z/OS has some amazing technology, I am sure it will still be around and as exciting in 20 years. I hope the new joiners will have as much fun as I had!
