The Sources interface in the Substrates API allows for a number of ways to set up a Subscriber and in turn an outlet Pipe. Subscribers provide the means to connect one or more Pipes with emitting Subjects within a Source. When a Percept (instrument) emits a value, that value is forwarded to all Pipes that have been connected by a Subscriber via a Registrar.

Observability: Cleanup Crew or Cartel?
Observability was supposed to bring clarity. Instead, it risks becoming the IT equivalent of a waste management cartel — collecting endless data, burying it out of sight, and billing handsomely for the privilege. Open standards like OpenTelemetry promised freedom, but they often just make dumping easier, not smarter. The sad truth is that most of what we collect will never be recycled into insight. We explore why the observability industry, much like modern waste management, thrives on accumulation — not renewal — and how fear, opacity, and misaligned incentives have turned what should have been green fields into digital landfills.
Beyond Pixels: Reframing Observability
The observability crisis isn’t about missing data; rather, it’s about missing meaning. While we’re inundated with metrics, traces, and logs, we’re simultaneously deprived of understanding. Our systems are narrating stories, yet we’re merely collecting the words. Confinement to a pixel-level fixation on metrics, traces, and logs renders today’s observability practices fundamentally retrospective. They measure the consequences, not the progression. They concentrate on fragments, not the underlying forces. To truly comprehend systems—to anticipate, guide, and sustain—we must transcend data collection and adopt the perception of dynamic narratives.
Managing Complex Systems
Drawing inspiration from the insights of cybernetics and systems thinking, we propose a cohesive framework centered around three essential, interacting functional components: Observability, Controllability, and Operability. This universal framework, underpinned by foundational capabilities (measurement, memory, and models), offers a potent lens for conceiving, comprehending, and controlling virtually any purposeful system, effectively bridging the disparity between abstract theoretical concepts and tangible practical applications.
The Existential Void in Observability
Modern observability suffers from an existential void, mistaking metric abundance for genuine understanding. Current practices emphasize granular measurement but neglect synthesizing comprehensive system insights. A paradigm shift toward continuous, holistic assessments of system stability and confidence—visualized as intuitive, dynamic representations—leverages innate human cognitive strengths. This transition addresses the root architectural flaw in current methodologies, replacing numerical theater with true insight into complex digital environments.
Why Observability Can’t Save Us
Dazzling dashboards, collapsing systems: Has observability become a beautiful lie? We've meticulously instrumented our complex digital world, yet meaningful insights remain elusive amidst a deluge of data. This post argues that the limitations of traditional observability in the face of emergent behaviors and dynamic topologies demand a radical shift towards a more comprehensive "situational intelligence" – one that moves beyond mere monitoring to true comprehension and proactive action. It's time to admit: observability alone can't save us.
Simplicity as Contextual Integrity
What if simplicity isn’t about wielding a machete to prune the excess, but about constructing a lighthouse whose beam remains clear and steadfast, piercing through any fog? We frequently envision simplicity as minimalism: a stark, uncluttered space, a reduction to the fundamental elements. It’s akin to stripping a machine down to its core components.
Serventis – A Semiotic Framework for Observability
This post introduces the Serventis framework, illuminating its semiotic architecture and demonstrating its power to transmute raw data into rich, resonant sense-making. We’ll explore how Serventis cultivates multi-agent intelligence, fosters situational awareness, and lays the bedrock for adaptive, self-aware systems.
Innovation: A Tale of Enterprise Failures
Stop chasing the elusive dream of becoming a hotbed of internal innovation. It’s a costly, frustrating, and often futile pursuit. Instead, embrace your true strength as a large, established enterprise: your ability to adopt, adapt, and scale the innovations of others. Be a smart, fast follower. Be a ruthless acquirer of promising technologies. Be a master of integration and optimization.
Why Observability Needed a Systems Engineer
Like a spacecraft with perfect sensors but no navigation intelligence, our tools measure everything while comprehending little. The administrator mindset treats observability as a data problem, capturing snapshots of system state through logs, metrics, and traces. In contrast, the engineer mindset sees it as a comprehension challenge, focusing on how events form sequences, how components create feedback loops, and how patterns emerge over time.
