Planning A Modernization Project? Read This First

October 18, 2021 Alex Woodie

Modernization means a lot of things to a lot of people. If you happen to ask Chris Koppe, the senior vice president of strategy, transformation, and modernization services at Fresche Solutions, what modernization means to him, get ready to spend the next hour listening to his response.

That’s the approximate length of Koppe’s recent presentation at the POWERUp conference, titled Developing Your Modernization Plan: What Are Your Options? and it’s worth every second. Koppe explored the topic in such breadth and depth that we though it was worth highlighting his main points. Of course, if you’re a COMMON member and …

The Ease Of API Programming Has To Be Balanced By Heightened API Security

October 18, 2021 Brian May

If you have modernized legacy applications or created new applications from scratch, you very likely have application programming interfaces, or APIs, exposed to enable applications to share data. To some ways of thinking, this sharing of data between chunks of code in a formalized way – within the organization or across code bases developed internally or created by third parties and residing on premises, in the cloud somewhere, or both – is what actually constitutes an application. The integrated whole is what makes everything work.

By their very nature, therefore, APIs are a boon to companies looking to weave together …

Guru: What Is Constant Folding And Why Should I Care About It?

October 18, 2021 Ted Holt

Constant folding is a compiler-optimization technique, whereby the compiler replaces calculations that involve constants with the result values when possible. Constant folding is common in modern compilers, and according to the RPG reference, the RPG compiler uses this technique. (See the documentation of the %div and %rem functions, for example.)

But you and I don’t write compilers. We write business applications. Why then should we care about constant folding? That’s a question worth pondering.

Consider how I used to have to write RPG in the Dark Ages.

As I See It: The Management Challenge

October 18, 2021 Victor Rozek

Imagine coaching an athletic team under the following conditions: Some percentage of your players do not practice in your facility. You have minimal contact with them, and even less influence over how, when, and how long they practice. Building and maintaining team cohesion is almost impossible. There’s a chance some of your players may be unavailable at some point during the season, and your training facility could be closed for an unspecified period of time. Yet you are still expected to win.

That’s roughly the situation in which managers find themselves. Some percentage of their employees probably still work from …

We Have The Whole World Of Cloud In Our Hands

October 18, 2021 Timothy Prickett Morgan

Cloud is a consumption model more than anything else, but it is also an architecture. What that really means is that for a lot of customers, on premises cloud is a bit different from what are called “public” clouds, which we all know are as proprietary as any System/3X or AS/400 or IBM i on Power Systems ever was. There ain’t nothing at all public about it, and we are trying to break the habit of calling them that. The point is, the big clouds outside of your datacenter look like power utilities, with pricing based on both time and …
