• Is It Worth Investing in IBM i and RPG?

  August 21, 2024 Alex Woodie

  Nobody is mistaking the IBM i server as a brand-new system. It can’t hide from its status as a legacy platform. But does that mean that it’s no longer worth investing in IBM i and RPG? That’s the focus of a new paper by the outsourcing company DDC FPO.

  DDC FPO is an Evergreen, Colorado-based business process outsourcing company that serves the trucking industry and specializes in things like freight billing and customer service for truckers. Considering the continued popularity of the IBM i server in the trucking business, it’s not surprising that DDC has taken an interest in the …

• Getting A Handle On What GenAI Might Cost

  August 21, 2024 Timothy Prickett Morgan

  Because of my other day job at The Next Platform, I can give you a pretty good idea about what it costs to train an AI model or run inference against it once it is trained. But I have seen very little data that tries to give any of a sense of what it costs to add generative AI functionality to applications.

  But interestingly, Gartner analysts embedded some such data in a report about how it expected many GenAI projects to be abandoned by the end of 2025 after their proofs of concept fail. That so many PoCs will …

• Some Thoughts On Big Blue’s GenAI Strategy For IBM i

  August 12, 2024 Timothy Prickett Morgan

  In a world that has gone half mad with generative AI, it is refreshing to see the people who control the IBM i platform being skeptical, hopeful, and practical about how the technology might be used to help the companies who choose Power Systems running IBM i as the platform for their mission critical applications.

  IBM Rochester has always been practical and often innovative when it comes to adopting hardware and software technologies, so the strategy that IBM i chief technology officer Steve Will laid out in a recent IBM i & AI – Strategy & Update as part of …

• Untangling Legacy Spaghetti Code To Cook Up Microservices

  August 12, 2024 Michel Mouchon

  At this point in the history of programming, everyone pretty much knows what microservices are and everybody is more than acquainted with the legacy code – and often monolithic code – that has been created over decades by countless programmers who have evolved corporate applications to fit new conditions and new demands.

  It is often called spaghetti code, and for good reason. The code is often a tangled mess of business logic and data – presumably the data is the meatballs and the user interface is the sauce in this metaphor. (It is important to not take a metaphor too …

• Guru: Creating A Web Service With Basic Authentication

  August 12, 2024 Mike Larsen

  I have been working with web services for many years, and I usually use IBM’s IWS (Integrated Web Service) tool to create them. The tool provides a wizard-based interface that allows me to quickly create a web service from an RPG program. Recently, I created a web service that uses basic authentication, and I want to share my experience.

  I am assuming that you are already familiar with creating a web server and a web service, so I am just going to show the steps that need to be taken to add basic authentication functionality. If you would like me …

• Kisco Names Two IBM i Fellowship Winners, Expands Program

  August 7, 2024 Alex Woodie

  Kisco Systems last month unveiled the next batch of recipients for its unique IBM i fellowship program. The individuals, who hail from Oklahoma and Georgia, will receive IBM i training from imPower Technologies and attend COMMON conferences in Florida and California at Kisco’s expense. The company also announced that it will expand the fellowship to three recipients next year.

  Justin Loeber, who purchased Kisco Systems from his father Richard in 2021, started the Richard C. Loeber Fellowship for Careers in IBM i last year as a way to incentivize the development of IBM i skills outside of the university setting. …

• Open Source IBM i Build Tool Now Supports VS Code

  July 24, 2024 Alex Woodie

  A new release of the open source iBuild tool now supports VS Code, the developer of the tool recently announced. The new release also now fully supports ILE, which is critical to the future of the IBM i platform, the iBuild creator says.

  iBuild is a free build tool that automates the task of running all of a developer’s RPG source code through the IBM compilers. It’s been in active development for about eight years and can be downloaded from sourceforge.net/projects/ibuild.

  What makes iBuild unique is that it puts instructions on how to build objects into the header of …

• Guru: Web Concepts For The RPG Developer, Part 3

  July 22, 2024 Chris Ringer

  Greetings everyone. Articles part one and two were both an introduction on how to build components in an HTTP request. In part three, we will begin to connect the dots and discuss how to asymmetrically sign a simple string. If you ever need to send a secure HTTP request to a government agency or financial institution, you likely will authenticate with a signed token. So, here we go!

  Base64 Take Two

  In part one, the SQL scalar function BASE64_ENCODE embedded in RPG converted a string to base64. This technique will cover most use cases, but what if you need …

• How To Contribute To IBM’s GenAI Code Assistant For RPG

  July 15, 2024 Timothy Prickett Morgan

  Back in October 2023, IBM launched its “Project Hopper” Watsonx Code Assistant for Z, which as the name suggests is a programming assistant that will eventually be built into the open source VS Code integrated development environment that was created by Microsoft and that is being explicitly trained to help programmers take applications coded in COBOL and convert them to Java. We speculated back then about how LLMs and GenAI might be used to do similar – and different – things for the IBM i platform, and back in May at the POWERUp 2024 conference Steve Will, the chief …

• IBM Begins the Purge of Old Greenscreen Utilities

  July 10, 2024 Alex Woodie

  IBM is prepping the IBM i community to prepare to adapt to some substantial changes that are coming with the next release of IBM i, including the end of support for a large swath of the Application Development ToolSet (ADTS) that ships with Rational Development Studio (RDS). Source Entry Utility (SEU) and Programming Development Manager (PDM) are not among the ADTS tools getting the boot, but that’s not stopping midrange professionals from speculating that their time in IBM i is limited, too.

  As part of its May 7 Technology Refresh for IBM i 7.4 and 7.5, IBM issued a “software …
