Sigwire is an open-source TUI that uses Linux kernel tracepoints to show every signal on a machine live, without strace or ptrace.
7 lessons from building a hard spending cap for LLM APIs
Why LLM API bills silently explode: retry storms, inconsistent token reporting, streaming blind spots, and race conditions in spending caps.
Enterprise AI Agents Are Now Runtime Products, Not Model Wrappers
Drawing on LangChain-NVIDIA's NemoClaw and Schneider Electric's LangSmith case study, this piece explains why enterprise AI agents are runtime products defined by permission boundaries, audit trails, and deployment—not just models.
CommitBrief — AI code reviews, right in your terminal
A provider-agnostic, local-first CLI that reviews your staged changes, a historic range, or a whole GitHub pull request. Zero telemetry, no server. Free and open source.
commitbrief.comState-harness detects LLM agent instability using control theory
Open-source state-harness library uses a Lyapunov energy function to catch token spirals in multi-turn LLM agents and explain failures without extra LLM calls.
AI Agent Cost Spikes Expose a Missing Observability Layer
Cost spikes in tool-using AI agents reveal a missing loop-level observability layer engineers need to attribute and govern spend.
Back-End Engineering in 2026: APIs Give Way to Agent Orchestration
Back-end engineering in 2026 shifts from stateless APIs to agentic systems: orchestration, async tasks, tool governance, and reasoning traces.
How AI Pinpointed the Root Cause of a Multi-Region K8s Outage
How Trendyol used an LLM to trace a multi-region Kubernetes outage to a systemd upgrade bug in under an hour, sifting 200MB of logs.
eBPF and TCX bring line-rate network visibility to hostile CI jobs
Blacksmith explains how eBPF programs attached via TCX and a host-side DNS proxy deliver line-rate network observability for untrusted CI VMs.
Trigger-tree tracks which docs your AI coding agent actually reads
trigger-tree is a local, zero-token tool that reveals which docs Claude Code or Codex agents actually read — and which ones they miss.
Beyond Logs: Why Metrics, Traces, and Cardinality Matter Most
A practical breakdown of metrics vs traces vs logs in observability, cardinality pitfalls, and why logs-to-metrics pipelines are an anti-pattern.
