eBPF: Correlating rustls Plaintext to TCP Connections Without a File Descriptor
Follow an eBPF debugging trail through rustls, Tokio inlining, and an empty map to learn how TLS plaintext gets matched to the right TCP connection.
Five Ways to Use OpenTelemetry Beyond Observability
Teams run inventory, security logs, request routing and billing through OpenTelemetry. Five non-observability uses, and the failure mode of each.
From Handwritten Mocks to proxymock: The Complete Loop
Part 10 of Getting Started with Mocks: use proxymock to record real API traffic, inject failures, verify side effects, and expose contract drift.
The Compounding Platform Tax
Security controls rarely break a banking platform alone. Their cumulative divergence from Kubernetes standards creates a compounding maintenance tax.
Your Observability Stack Found the Fire. Congratulations.
Observability tells you when production is on fire. Capturing and replaying real traffic lets you recreate the incident, verify the fix, and keep it fixed.
I built an API traffic classifier for business workflows
I pointed a classifier at 7,943 API calls to find business workflows. It worked, then showed where my assumptions about sessions and patterns fell apart.
Reliability Engineering in the AI Era
See why reliability engineering must span code, testing, telemetry, and incidents as AI agents erase the boundary between pre-production and production.
From Telemetry to Traffic
Compare eBPF, sidecars, telemetry agents, OpenTelemetry, APM, and proxies through an evolving ladder of production visibility.
