    Work From Home Works—But Only When You Design It to Work

    Work From Home Works—But Only When You Design It to Work

    By a Mainfram Nerd with Two Monitors, a Standing Desk, and a Deep Respect for Team WhiteboardsWhen the world flipped its working rhythm in 2020, most of us in IT didn’t miss a beat. We kept the systems humming, patched the holes, scaled the VPNs, and figured out how to keep the company’s backbone alive without the benefit of hallway conversations and desk drive-bys.Five years on, it’s time to get

    🧩 At Scale, Time Is Your Strongest (or Weakest) Link

    When your system hits 1 million TPS, milliseconds aren’t enough.Every microservice, log, and transaction wants to know: "What happened, exactly when?"And if you're still timestamping in milliseconds — congrats — you just grouped 1,000 transactions under the same time.That’s a challenge for:🔁 Ordering🔍 Auditing🧩 Debugging📦 Replication🧠 ObservabilityLet’s talk timestamp granularity, how to impl

    Gate Delay 3270 Chapter Five: The Gate Opens

    Gate Delay 3270 Chapter Five: The Gate Opens

    The loudspeaker finally crackled to life, and the terminal buzzed with a new energy. The delayedflight to Spain was now boarding. Gate 21. Final call.Jamie groaned as they unfolded from the low airport seat. “I forgot we were actually goingsomewhere.”Alex stretched like a cat. “Same. Mentally I’ve already aged three years in this terminal.”Dana was packing away her tablet, but slower than before.

    Gate Delay 3270 Chapter Four: Stories from the Steel

    The low murmur of the terminal had settled into something almost peaceful. The cleaning crewpassed quietly, wheels squeaking. Somewhere down the corridor, a child was giggling aboutabsolutely nothing. And in their little corner by the oversized windows, the group sat in the mellow stillness that comes after tech debates and caffeine crashes.Dana looked over at Frank. “Alright. No more architecture

    Gate Delay 3270 Chapter Three: The God Machine Nobody Talks About

    The coffee stand had closed. Jamie’s laptop battery had died a noble but silent death. Alex had taken over the only working power outlet, and Sam had turned his hoodie into a pillow and was dozing lightly on the floor.Frank, meanwhile, was rummaging through his bag like a man about to cast a spell.“Behold,” he announced, dramatically producing… a printed diagram. Folded. Laminated. Possibly older

    Gate Delay 3270 Chapter Two: The Marketing Problem

    The airport lighting had shifted subtly, from harsh white to that late-afternoon honeyed hue thatmade everything look vaguely nostalgic. The screens still showed the same red DELAYEDmessage, and the terminal speakers had fallen into an awkward silence, as if even the announcement system was unsure what came next.Jamie closed their laptop with a sigh. “You know,” they said, staring into the middle

    The Mainframe Vocabulary Problem (And Why It Matters)

    The Mainframe Vocabulary Problem (And Why It Matters)

    "Can you IPL the system before the batch window starts? Make sure the PARMLIB updates are in, or RACF will block access again. And watch the ZEBRA logs—if they spike, we’ll have to rerun the FDRs."For someone new to mainframes, a sentence like that can feel like stepping into a conversation that’s already halfway over. It’s easy to get lost. But for those who’ve been working on these systems for y

    Elon Needs Some Schooling: The Real Cost of Rebuilding Social Security’s Mainframe

    Elon Musk’s Department of Government Efficiency (DOGE) is on a mission to replace the Social Security Administration’s (SSA) mainframe systems—decades in the making and battle-tested—with a shiny new Java-based platform. The problem? It’s a wildly reckless move that completely ignores the technical, financial, and logistical realities of such a transition. We’ve seen this before. Big tech swoops i

    Innovation Isn’t New Here—It’s Tradition

    The Role of Mainframe Teams in Enterprise ComputingIn the world of enterprise computing, Mainframe teams often navigate unique constraints—technical standards, compliance mandates, strict up-time requirements, transparent charge-back models, and the ever-present demand for efficiency. To an outsider, these limitations might seem trivial. But to those within the Mainframe space, they serve as a cat

    Why Mainframe Work Should Feel Like a Good Game

    Why Mainframe Work Should Feel Like a Good Game

    I was talking to a mainframer the other day—let’s call him Dave.Dave has been in this business for longer than some of his teammates have been alive. He remembers punch cards. He remembers when someone accidentally deleted a dataset and nearly took down the entire payroll system. He remembers when the only way to debug a problem was printing out thousands of lines of logs and physically flipping t

    Getting to know the ISPF editor a little better

    Getting to know the ISPF editor a little better

    IntroductionISPF is my opinion seriously undervalued as a whole, but the ISPF editor specifically misses out on the spotlight it deserves. So while there are endless articles about modern IDE’s like VSCode, IDZ, Topaz etc., and don’t get me wrong, each of those tools is excellent in their own right, there are not nearly as many good articles about the ISPF editor. And even though you might spend m

    How can we improve accessibility for all in enterprise IT?

    Technology is more advanced than at any other point in history but it’s still not accessible to all, despite equality, diversity and inclusiveness being key issues in the workplace. Can we learn from past mistakes and improve accessibility? How can we open up what may be a closed-mind organization?Accessibility matters. Especially when you read that disabled people are disproportionately unemploye
