• Stop Coding In C and C++, Feds Say

  December 2, 2024 Alex Woodie

  Two federal agencies asked the IT world last month to stop developing applications in memory unsafe languages like C and C++ and to come up with roadmaps to migrate existing apps. While the security alert is unlikely to have a major impact on IBM i application development, the C family of languages does have a presence on the IBM midrange server that will be very tough to remove.

  Organizations should immediately stop developing new applications written in memory unsafe languages like C and C++, the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigations (FBI) warned last …

• IBM’s Fall 2024 Code for IBM i Enhancements

  November 13, 2024 Alex Woodie

  Adoption of Code for i continues to soar among IBM i developers, as they shift from heavy, expensive integrated development environments (IDEs) to lighter, open-source options. With the latest Technology Refreshes (TRs) for IBM i, IBM is making the VS Code plug-in even more useful for RPG and COBOL developers.

  Code for IBM i is the brainchild of Liam Allan, the midrange wunderkind with an intense aversion to Rational Developer for IBM i (RDi), IBM’s Java-based flagship IDE for IBM i. As adoption of the VS Code extension grew in the summer of 2022, IBM smartly hired Allan as a …

• Fresche Nabs Redbourn Business Systems For Synon Expertise

  November 11, 2024 Alex Woodie

  Fresche Solutions last week acquired Redbourn Business Systems, a UK-based provider of Synon and CA 2E development and consulting services. The move bolsters Fresche’s previous efforts to cater to the needs of IBM i shops that adopted the Synon/2E development language, and also bolsters the company’s European presence.

  Redbourn Business Systems was founded in 1994 by Steve Cast, a longtime RPG programmer and IBM midrange professional who was among the first to port applications from the System/38 to the AS/400 back in the 1980s. The company, which is based in the English village of Redbourn, provides a range of services …

• Guru: RPG Receives Enumerator Operator

  November 11, 2024 Gregory Simmons

  The RPG language now (some would argue, finally) has an enumerator operator. This was introduced in IBM i 7.5 TR3 and IBM i 7.4 TR9.

  DISCLAIMER: The edibility of the mushrooms listed in my test program are purely to give the program some context and make it interesting. Their edible status is based on information from the Missouri Department of Conservation’s publication A Guide to Missouri’s Edible and Poisonous Mushrooms. Before foraging for or consuming any wild mushroom do your research and be safe.

  Let’s dive right into a code sample. We’ll start with a simple linear-main program …

• IBM i PTF Guide, Volume 26, Number 44

  November 11, 2024 Doug Bidwell

  The number of patches slowed down last week, and we are not sure if that had anything to do with the election in the United States, but what we do know is we all got a break. And we will take it, and then get back to work.

  There are a number of security vulnerabilities with WebSphere middleware, an issue with drive logging, and several fixes for TGTRLS in the RPG compilers.

  First, we have Security Bulletin: IBM WebSphere Application Server is vulnerable to an XML External Entity Injection (XXE) vulnerability (CVE-2024-45086), which you can read about here. This …

• Another GenAI-Powered Testing Tool Comes to IBM i

  November 6, 2024 Alex Woodie

  IBM says it’s bringing a new AI accelerator to the Power line to drive compute-hungry generative AI workloads, such as the new RPG coding assistant that it’s also developing. But IBM won’t be the only source of such GenAI-powered coding assistants, as a company called Abstracta recently announced another one.

  There’s a lot of interest in the Spyre accelerators that IBM announced earlier this year for the System z mainframe and which IBM announced last month during its TechExchange conference will be coming to Power. Considering the massive demand for Nvidia GPUs, which could plug into past generations of Power …

• RPG Code Assist Is The Killer App For AI-Enhanced Power Systems

  October 23, 2024 Timothy Prickett Morgan

  “I love it when a plan comes together.” – Colonel John “Hannibal” Smith, The A Team.

  Look, we take our wisdom and our joy where we can find it here at The Four Hundred, and it does indeed look like Big Blue has a plan that is coming together with regards to generative AI and the Power Systems hardware platform as it relates to the IBM i software platform.

  We told you in Monday’s issue that IBM was up to something with regard to the Power Systems line, which was revealed to partners and presumably key …

• Guru: Web Concepts For The RPG Developer, Part 4

  October 21, 2024 Chris Ringer

  The final article in this series is about the JWT (JSON Web Token). If you wish to review the previous articles, you can drill back from part three. For unattended machine to machine (M2M) processes, a JWT string is a formatted container for requesting access to a resource server. I think of a resource server as the applications. And in our case, the JWT has an asymmetric signature.

  But really, what is a JWT? It’s similar to a temporary driver’s license. Think about your last visit to a hotel (figure 1).

  Steps:

  1. You present your ID (JWT) during check-in

• How To Have The Wisdom Of Experts Woven Into Your Code

  October 14, 2024 Nicholas DeLessio

  No matter how far you are down the road with your DevOps automation journey, or even if you’re not yet starting that journey, it’s probably a good idea to have a code checker; not everyone can have a Linus Torvalds review their work (as famously happens with the open source Linux kernel), but there are automation tools available for various languages and platforms that do static code analysis and they are the next best thing.

  These tools, sometimes called “code linters” (because they remove the fuzzy bits out of application logic like actual linters remove imperfections stuck to our clothing), …

• Surprise! It’s 2024 Fall TR Time for IBM i

  October 9, 2024 Alex Woodie

  IBM announced the Technology Refreshes (TRs) for IBM i version 7.5 and 7.4 yesterday, bringing a host of new capabilities to the proprietary operating system. As expected, the surprise update covers a range of IBM i facilities, including Db2, Navigator, ACS, PowerHA, and the development tools.

  Navigator gets several more enhancements with the new TRs, including: a new dashboard with software licensing information; Web-based administration of network facilities; support for monitoring of Java 11 and Java 17 jobs; enhancements to the Performance Data Investigator (PDI); and new options for working with audit journals, among other capabilities.

  IBM also includes the …
