• Retranslation Could Boost Performance

  May 13, 2019 Timothy Prickett Morgan

  There are so many kinds of genius embedded into the IBM midrange line that it is hard to know where to begin when discussing all of these interconnected ideas and layers. But perhaps the simplest way to encapsulate them all is that the System/38 and AS/400 minicomputers and their follow-ons sought to abstract away and mask some of the more complex aspects of a modern system so that programmers could focus on business logic and system administrators could focus at a much higher level, too.

  One of the key differentiators of these IBM midrange platforms, and one of the hallmarks …

• Mad Dog 21/21: In Memory of Hesh Wiener

  April 29, 2019 Timothy Prickett Morgan

  “Stop complaining. The only thing worse than writing so many obituaries is having one written about you. Let me assure you.”

  If my friend and mentor, Hesh Wiener, were alive today, that is what he would say to me with a laugh. And of course, as always, Hesh, who had no intention of leaving this world quite yet, would have been right.

  We have suffered our share of losses in the IBM midrange in recent years, and here at The Four Hundred, the publication that Hesh created in the wake of the inaugural June 21, 1988, AS/400 announcements. Hesh …

• RTPA Looking For A Few Good Software Reviewers

  April 8, 2019 Timothy Prickett Morgan

  Throughout the six decades of commercial computing, one thing has been universally true. Every good application development or system management tool, from the simplest debuggers all the way up to complex DevOps systems that can absorb multiple continuous streams of new code being mashed up against old code without making a mess of things, got its start because some programmer or administrator was so annoyed at how something worked – or more precisely didn’t work – that he or she created a new tool that did the job a whole lot better.

  This is precisely the beginning story of Real-Time …

• Are You Experienced? IBM i Users Weigh In

  March 18, 2019 Timothy Prickett Morgan

  We spend a lot of time here at The Four Hundred thinking about the vintage of the hardware, operating systems, and applications running on the IBM i platform and its forbears. But we are also concerned, as you know, with the vintage of the people who are running and programming the systems out there in the IBM midrange installed base.

  It is hard to get any quantifiable data on the people out there running the platforms – and we thank you, as loyal readers of this publication for several decades now for being in this market for even more decades …

• Goosing Big Iron Power Systems With Power9 Migrations

  December 3, 2018 Timothy Prickett Morgan

  The Power9-based servers from IBM’s Cognitive Systems division have been rolling out over the course of the past year, and the big iron has been in the field only since the late summer but has perhaps had the largest impact on the revenue and profit stream for the Power Systems line, excepting maybe the installation of the “Summit” and “Sierra” supercomputers for the U.S. Department of Energy’s Oak Ridge National Laboratory and Lawrence Livermore Laboratory.

  As has been the case since the AS/400 line debuted in 1988 and even with the combination of the System/36 (low-end and midrange) and System/38 …

• A Platform Of A Certain Age And Respectability

  June 20, 2018 Timothy Prickett Morgan

  Outliving your enemies is one of the best kinds of revenge, if you happen to have any enemies. But the people of Rochester, Minnesota, did not really have many enemies, although they did build a system that has outlived its many rivals and that continues to co-exist alongside newer platforms that are, quite frankly, still difficult and expensive to use.

  That the AS/400 is celebrating its 30th birthday this week, and the IBM i platform running on Power Systems is still around and still a viable business, is nothing short of remarkable. We know this because we just remarked upon …

• What A Concept: Distribution Software Aimed At Real SMBs

  April 9, 2018 Timothy Prickett Morgan

  Time may pass in the IBM midrange, and systems and business practices have evolved, but the one thing that does not change is that some companies, especially those on the smaller size with limited resources to devote to IT hardware and software, want a simple system that just lets them do the work they need to do.

  The simplicity of the System/3X family, which has its start way back with the System/3 in 1969 and runs up through the System/38 in 1979 and the System/36 in 1983, up through the AS/400 in 1988 and up through the iSeries, System i, …
