  • The Temple and the Error Budget

    The Temple and the Error Budget

    What happens when you put Solomon’s Temple next to a modern error budget and ask them both what “perfection” really means? In this episode, we explore the idea that reliable service is not just a technical outcome but a moral consequence — the visible result of character, duty, and brotherly love expressed through IT work.

    Drawing on Freemasonry, Stoic philosophy, and the writings of Marcus Aurelius, we unpack what it means to work logarithmically toward an ideal you will never fully reach. We contrast the Masonic Temple and its working tools with SRE and ITIL principles: why 100% uptime is the wrong target, how continual improvement mirrors lifelong moral refinement, and how duty becomes the backbone of both spiritual life and professional reliability.

    Then we zoom in on the real builders of today’s “Temple”: the backup and recovery specialist guarding the sacred data; the infrastructure engineer hewing and setting the foundation; the Citrix/WebSphere/DB2 specialist adorning the inward workings; the mainframe programmer quietly automating away chaos; and the mainframe operator keeping vigil in the sanctum of production. By the end, your ticket queue, your runbooks, and your change windows look less like random toil and more like stonework on a shared, enduring structure.

  • From Rough Ashlar to Righteous Re-Engineer

    From Rough Ashlar to Righteous Re-Engineer

    This episode reflects on the journey from Rebellion to Responsibility, tracing how both individuals and systems evolve through disciplined self-correction. We explore the Masonic allegory of the Rough Ashlar—a person full of natural flaws—being refined into the Perfect Ashlar through the Common Gavel, symbolizing self-discipline and reflection.

    The 1980s punk scene serves as a living example of the unrefined Ashlar: a volatile system rejecting all authority. SLC Punk captures its collapse when chaos meets consequence—most tragically in Heroin Bob’s death. The Straight Edge movement emerged as a self-imposed reformation, a kind of ethical debugging through sobriety and restraint.

    Maturity, then, is Righteous Re-Engineering—transforming rebellion into mastery. When Stevo chooses law over anarchy, he embodies the truth that sustainable change requires structure. In both character and code, reliability is born not from chaos, but from conscious design.

  • The Square and the Server

    The Square and the Server

    In this episode, Change Advisory Board draws a straight line from the lodge to the datacenter via the square, exploring how the symbolic working tools of Freemasonry — the gauge, gavel, square, level, plumb, compasses, and trowel — can be reinterpreted as instruments of modern Site Reliability Engineering.

    From the Entered Apprentice’s 24-inch gauge to the SRE’s time budgets and service-level objectives, each tool becomes a lens for understanding the moral and operational discipline behind reliable systems. The common gavel’s task of removing rough edges parallels how engineers refine noise from telemetry. The Fellow Craft’s square and level emerge as early templates for data integrity and fairness — the moral geometry of incident response. The plumb rule, once a test of uprightness, becomes the model for aligned observability: systems and people both measured against their true vertical.

    Finally, the Master Mason’s compasses and trowel remind us that every great system — like every enduring fraternity — is held together not by code alone but by the invisible cement of trust, accountability, and shared purpose. Observability, in this light, is not just about data; it is the moral act of ensuring that what we build is true, just, and aligned with the architecture of higher principles.

    It’s a conversation about craftsmanship in code and in character — an investigation into how the oldest working tools of humanity still guide the newest disciplines of reliability engineering.

  • The Watchtower and the Mirror

    The Watchtower and the Mirror

    This episode examines modern software maintenance practices, specifically Monitoring and Observability, through the lens of Masonic symbolism to illustrate principles of operational wisdom. Monitoring is aligned with the Watchtower, focusing on tracking real-time quantitative data about known system conditions, much like a Tiler guards a perimeter to detect anticipated problems. In contrast, Observability is compared to the All-Seeing Eye and the Mirror, representing the capacity to ask questions about a system’s inner workings to troubleshoot novel problems or “unknown unknowns.” Together, these concepts constitute the operational wisdom required by Site Reliability Engineers (SREs), which is further mapped onto the Masonic pillars of Wisdom, Strength, and Beauty to guide the pursuit of system reliability, efficiency, and continuous improvement.
