• IBM i PTF Guide, Volume 23, Number 42

  October 20, 2021 Doug Bidwell

  It’s a mixed bag for Program Temporary Fixes, or PTFs, for the supported releases of the IBM i operating system, with some tweaks here and there and some High Impact/Pervasive, or HIPER, patches coming out for IBM i 7.4 and IBM i 7.3.

  A relatively quiet week is a good thing about this time of the year, with the fall season underway and everyone gathering up strength to do push through the final two months of the year once Halloween gets here. (That is a line of demarcation, isn’t it?) We are not expecting a lot in the way of …

• 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 …

  October 13, 2021 Alex Woodie

  As the vice president and global offering management for Cognitive Systems at IBM, Steve Sibley often gets the honor of delivering the keynote address at the annual POWERUp conference.

• End of Life Looms for PHP 7.3

  October 13, 2021 Alex Woodie

  Organizations that are running PHP version 7.3 have just over a month to upgrade to a newer version and avoid losing bug fixes and security fixes when 7.3 hits the end of life (EOL) on December 6. The good news is that PHP version 7.4 and 8.0 are stable and will be supported for some time. The not-so-good news is it appears a large number of IBM i shops are still running older releases of the PHP language.

  According to an informal poll conducted by Seiden Group last month, about half of the IBM i shops that participated in a …

• Rewriting IBM i RPG Software Is Almost Always A Bad Idea

  October 13, 2021 Roger Pence

  There are perils and pitfalls in attempting to rewrite your IBM i-AS/400 RPG applications. While there are some cases where such an attempt may be a good idea, you need to consider the big rewrite option carefully from every angle. It is often the worst step you can take.

  As you start to realize that your IBM i RPG software, at least in its current form, is nearing the end of its useful life, rewriting your RPG application is an obvious alternative. We implore you to give this option very serious consideration before you jump into it. Rewriting a large, …
