Keep Your IBM i Baby, Not The Bathwater

May 7, 2018 Alex Woodie

In the quest to modernize computer systems, some IBM i shops cease being IBM i shops. Wholesale migrations or complete rewrites of applications on different operating systems are sometimes necessary and beneficial, and sometimes they do more harm than good. When King III Solutions set out to enhance its advanced replenishment system, it managed to create a modern Web front-end that resonates with millennials without giving up its rock-solid IBM i back-end.

Based in Marietta, Georgia, King III Solutions, or K3S, develops software that helps wholesale distributors and retailers better manage their inventory, in part through a collection of …

IBM Wheels And Deals To Boost Power System Sales

May 7, 2018 Timothy Prickett Morgan

A lot of the revenue that comes to the Power Systems division – and perhaps the bulk of it if history and the changed nature of the product line is any guide – comes from relatively big iron machines, at least by IBM i standards for what is little, middle, and big iron. And IBM needs to do something here in early 2018 to keep customers of big iron boxes investing while it prepares to ship machines with four sockets or more of the Power9 processors under a schedule that we told you about back in February and that seems …

Guru: Refactoring into Routines

May 7, 2018 Ted Holt

In RDi and Refactoring, I illustrated the process of refactoring by taking code of a very old style and converting it little by little into something modern. I promised to write more about the subject, and today I fulfill that promise.

The things I did in that first article — removing indicators, removing the COMP op code, removing GOTO, and renaming variables — are great, but they are not the only refactoring techniques. One of the best ways to refactor is to create new routines or improve existing routines, especially routines that can stand alone.

To illustrate, I’ll begin …

As I See It: The Long And Intertwined Road

May 7, 2018 Victor Rozek

I’m part Neanderthal. No, that’s not just my wife’s opinion. Nor is it an unkind conclusion based on observation, although that could be open to debate. In fact, my wife is part Neanderthal, too, a data point that invites further comment but could only get me into trouble.

The bearer of this startling revelation is an organization long celebrated for its examination of such diverse, yet interconnected subjects as history, culture, science, and the environment. Its playground was, and continues to be, planet Earth. From its early days as a sponsor of exploration; to producing a publication so beloved that, …

Spring Cleaning In IBM i Land

May 7, 2018 Timothy Prickett Morgan

It has been a busy couple of weeks with IBM winding down a whole bunch of different products related to the IBM i platform. It is a kind of spring cleaning, we suppose. IBM doesn’t usually offer explanations for its decision to discontinue products, so we just have to take them at face value. Sometimes there are upgraded or replacement products, and sometimes it is just the end of the line.

In announcement letter 918-056, IBM says that it will be withdrawing the 7042-CR9 Hardware Management Console (HMC), and moreover, IBM says that going forward, support for the Model …
