Looking Back at 2016
This is the second post where I look back at 2016 with some reflections on the most useful and interesting topics that I explored in the year that just passed. I really enjoyed writing the series on modernization, sig-nif-i-cance and the cloud economy. Modernization was a topic I knew about but never fully explored. It was timely to write about the cloud economy as it was a hot topic in 2016. The sig-nif-i-cance series was fun for me to indulge in and re-explore some of my favorite topics. Here is a quick recap.

When the thumb drive was put back into IBM i, the PTFs could not be loaded.
Our Top 5 Highlights of 2016
It's a new year so it seems like a good time to reflect on the year that has just passed.
Many things happened in the IBM i world in 2016 but we've come up with a list of five of the key things that impacted us significantly, mostly for the better. See how many of these would make your own list of highlights.
IBM i Future – 2017 Update
One of the most common questions people ask me is “What’s the future for IBM i?”
I think I’ve gotten that question 20 or more times since the start of the year--via e-mail, LinkedIn messages, customer briefings, Twitter direct messages--and as I write this, I have only been at work for eight days in 2017. And this is the slow part of the year.
DB2 12 for z/OS Technical Overview
I don't need to tell you that a career working with DB2 for z/OS is never boring. DB2 for z/OS continues to evolve at an ever-increasing pace. To help you keep up with all these changes, IBM has delivered a new Redbook, "DB2 12 for z/OS Technical Overview."
Thoughts on Performance Tuning
I recently discovered this post to the UNIX & Linux Forums. While it's from 2013, "The Most Incomplete Guide to Performance Tuning" has some great -- and still relevant -- ideas.
