• Guru: Procedure Driven RPG And Adopting The Pillars Of Object-Oriented Programming

  February 19, 2024 Gregory Simmons

  The four pillars of object-oriented programming (OOP): abstraction, encapsulation, inheritance, and polymorphism, were not created at a single point in time. They evolved gradually over several years, with contributions from various researchers and programmers. Here’s a brief overview of their evolution:

  1. Abstraction:

  • Alan Kay is credited with introducing the concept of abstraction in the 1960s with his work on Simula.
  • Abstraction gained further traction with the development of Smalltalk in the 1970s.

  2. Encapsulation:

  • David Parnas, in his 1972 paper “On the Criteria To Be Used in Decomposing Systems into Modules,” laid the groundwork for encapsulation by emphasizing the importance of

• IBM: A Brand Is Not Everything, But It Is Important To Have A Good One

  February 19, 2024 Timothy Prickett Morgan

  If you want to trace the roots of Big Blue back to the beginning, you start with Herman Hollerith at Columbia University and the punch card tabulating machines he created and that were ultimately used in their first big commercial application to do the calculating for the US Census in 1890.

  Back then, mainframes were made of wood, copper, and paper, and in 1911, Hollerith’s punch card machine business, known as the Tabulating Machine Co, were united with the Dayton Counter Scales, Dayton Industrial Scales, and International Time Recorder machines that were part and parcel of the Industrial Revolution. The …

• IBM i PTF Guide, Volume 26, Number 7

  February 19, 2024 Doug Bidwell

  Aside from two new security vulnerabilities, it has been a pretty quiet week in IBM i PTF Land. There are some updates for the current releases of IBM i – that would be IBM i 7.4 and IBM i 7.5 that are both on standard support and IBM i 7.3 that is on extended support – and of course there are some new defective PTFs that Big Blue needs to make you aware of, as often happens because all modern platforms are complex and all of them sometimes have patches that have unintended consequences.

  Let’s start with the security issues, …

• Gird Yourself for Digital Transformation Failures in 2024

  February 14, 2024 Alex Woodie

  Spring is still more than a month away in the Northern Hemisphere, but change is already in the air when it comes to enterprise IT departments in 2024, who are under the gun to accelerate digital transformation initiatives, particularly those involving artificial intelligence and the cloud. Rosy predictions of business bliss typically accompany the start of these projects, but the reality is most of them are likely to go off the rails and end in IT failures.

  That’s the informed opinion of Eric Kimberling, the CEO of Third Stage Consulting and a grizzled veteran of ERP implementations and digital transformation …

• Hybrid Release Management Means Creating An Application Schema

  February 14, 2024 Marc Dallas

  In a hybrid computing world, no application is an island and similarly no system running those applications and the databases underpinning those applications can be an island, either. And yet, many IBM i shops still behave as if they can be islands when it comes to application release management.

  Despite this, based on our own experience and the anecdotal evidence we gather from IBM i shops like yours, there is a clear separation between release deployment in the IBM i world and the “other” release deployments in the enterprise. We need to talk about this.

  First of all, application deployment …

• Dynatrace Includes IBM i In Its Observability Bubble

  February 14, 2024 Alex Woodie

  If you’re looking for an observability tool that supports IBM i, you might want to consider Dynatrace. At first blush, you might suspect the application performance management (APM) experts at Dynatrace have better things to do than to support a proprietary midrange server used viewed as niche by the computing public. But in fact, Dynatrace appears to have devoted substantial resources to supporting the IBM i platform.

  Dynatrace is best known for providing enterprise-level APM tools that track down performance issues in complex, multi-tiered applications that involve multiple operating systems, hypervisors, databases, application servers, and sundry other enterprise computing kit. …

• Server And Storage Spending To Recover In The Years Ahead

  February 14, 2024 Timothy Prickett Morgan

  A decade and a half ago, there was a very formal definition of what cloud infrastructure was, and the distinction between what most IT departments acquired or leased and what was rentable in the nascent clouds was obvious. Over the years, the lines have gotten fuzzier, with you being able to acquire systems with utility-style cloud pricing even though they are in your datacenter – just to give one example. Another is something called a bare metal cloud – what you and I might have called hosting in days gone by.

  That fuzziness is why we always take any prognostications …

• The State Of The Power Systems Base 2024: The Operating Systems

  February 12, 2024 Timothy Prickett Morgan

  What stays in the field longer? The hardware or the software? Well, if you are talking about the IBM i installed base, or indeed that of any legacy systems out there like z/OS or Windows Server, the hardware can often be upgraded easier than the software and so it tends to not stay in the field as long. On average, of course.

  In the real world, it all comes down to specifics. And you have to analyze and interpret the trend lines very carefully so as to not jump to the wrong conclusions.

  So it is with the decade long …

• Thoroughly Modern: From Tradition To Transformation For IBM i In The Era Of Cloud And AI

  February 12, 2024 Monica Sanchez

  The value of IBM i is undeniable, especially if you are running an IBM i shop. But that does not mean IT leaders can ignore pivotal market changes in cloud, cybersecurity, and AI. These disruptive forces all have something in common – they are driving change. They are shaping operations and future strategies, pushing IT leaders to innovate.

  As we dig deeper into these transformative forces, it becomes clearer that the path forward for IBM i shops is all about continuous evolution and strategic foresight.
