Context drift -- not latency, not cost -- is what kills autonomous fleet operations at scale.https://ure.us/articles/why-foreign-ai-specialists-keep-failing/Mon, 02 Feb 2026 00:00:00 +0000https://ure.us/articles/why-foreign-ai-specialists-keep-failing/AI context is now portable - but domain gravity and the human translation layer still decide who wins when building real products in real markets.https://ure.us/articles/cold-aisle-trenches-you-dont-chase-lights-out-you-earn-it/Thu, 29 Jan 2026 00:00:00 +0000https://ure.us/articles/cold-aisle-trenches-you-dont-chase-lights-out-you-earn-it/A real outage story showing why lights-out operations require guardrails: ticketed access, intent-based authorization, OOB management, and safe rebuild limits.https://ure.us/articles/from-security-to-resilience-defense-in-depth/Thu, 22 Jan 2026 00:00:00 +0000https://ure.us/articles/from-security-to-resilience-defense-in-depth/Multi-tenant cloud security is resilience: detect, contain, and recover faster than adversaries can escalate, without violating tenant privacy.https://ure.us/articles/when-the-constraint-isnt-capacity/Tue, 20 Jan 2026 00:00:00 +0000https://ure.us/articles/when-the-constraint-isnt-capacity/A bootstorm incident that looked like capacity pressure, until instrumentation revealed a non-existent SQL dependency stalling every request path.https://ure.us/articles/why-gpu-fleet-control-starts-with-a-map/Wed, 07 Jan 2026 00:00:00 +0000https://ure.us/articles/why-gpu-fleet-control-starts-with-a-map/GPU operations starts with footprint truth: a living map of where compute really is, across sites, standards, and drift.https://ure.us/articles/project-atlas-technical-stack/Mon, 05 Jan 2026 00:00:00 +0000https://ure.us/articles/project-atlas-technical-stack/Technical architecture of Atlas: Redpanda, TimescaleDB, Hasura GraphQL, and deck.gl for capacity planning and workload placement.https://ure.us/articles/telemetry-that-lies-gpu-thermal-monitoring/Sat, 27 Dec 2025 00:00:00 +0000https://ure.us/articles/telemetry-that-lies-gpu-thermal-monitoring/Your GPUs report 100% utilization while running slower. Temperatures look fine while racks drift hot. Thermal telemetry is easy to collect and hard to trust.https://ure.us/articles/ai-infrastructure-placement-business-decision/Thu, 11 Dec 2025 00:00:00 +0000https://ure.us/articles/ai-infrastructure-placement-business-decision/AI compute can't be cached at the edge. Every inference needs real GPU cycles. Latency rings reveal which populations get responsive AI -and which don't.
