Mainframe Innovation, Reimagined

By | December 29th, 2015|Agile Development, DevOps|

Until recently the mainframe environment at most organizations has been treated like a black box: executives knew it accomplished significant work and it involved significant budget line items but preferred to leave it to its own devices. However, dramatic changes are afoot.

Topaz Runtime Visualizer: Opening the “Black Box” of Mainframe Applications

By | October 28th, 2015|Agile Development, DevOps, Featured|

There is an emerging phenomenon in IT: developers working on systems that are older than they are. While not unique to the mainframe (think Windows or Word), it is becoming more and more prevalent on the mainframe. Think of it. As this developer was learning to walk the application was [...]

Musings & Observations from SHARE Orlando 2015 Blog Series – August 13 (Final Day)

By | August 13th, 2015|DevOps, Featured|

Some final observations about SHARE Orlando: SHARE isn’t just our name. It’s what we do. I love the User Experiences sessions. The best presentation is a story and these sessions are the best stories, often describing a journey that isn’t complete yet. I remember looking around during session 17619 Modernization Real Life Scenarios and thinking “they’re needs to be more people here!”

Bumbershoot is the big music festival in Seattle. For one fixed price you can roam the grounds and take in music from any of half a dozen stages. There are hard choices to be made. Every time you choose to listen at one stage you are also choosing to skip the music available on the other stages. That same principle is true at SHARE as well. Every session you choose to attend means you’re also choosing not to attend the other ten or so sessions occurring at the same time. That makes for some hard choices too.
