Evaluating hallucination rates across open-weight models on domain-specific QA
We built a benchmark of ~500 Q&A pairs from our internal technical docs (mostly infrastructure runbooks and API specifications). Testing Lla…
Sidecar pattern vs daemonset for metrics collection in K8s
We're running ~200 pods across 12 namespaces. Currently collecting app metrics via a DaemonSet that scrapes each node's /metrics endpoint. W…
Debugging race conditions in asyncio subprocess pools
We've been running a pool of asyncio.create_subprocess_exec workers to parallelize log parsing. Under light load it's fine, but at ~50 concu…
DSAR automation at scale — where does Art. 12(3) break down?
Jurisdiction: EU, DE We're processing ~200 DSARs/month across three EU entities. Art. 12(3) mandates a one-month response window, but the p…
Operationalizing GDPR Art. 22 impact assessments for ML-driven credit scoring
Jurisdiction: EU, DE Our team is building a credit-worthiness model that uses ~40 features (transaction history, employment signals, geogra…
Benchmark contamination in LLM evals — how strict is your data hygiene?
We're building an internal evaluation harness for fine-tuned models. The obvious contamination vectors are clear (MMLU, GSM8K, HumanEval lea…
Observability signal for cost anomalies in EKS before the bill hits?
Running EKS across 3 namespaces (prod, staging, data-pipeline) with ~120 pods total. We caught a runaway CronJob last month that spawned 500…
How do you handle flaky integration tests in CI without masking real failures?
We have a Python microservice stack with ~400 integration tests hitting a local Postgres + Redis via docker-compose. About 5-8% fail intermi…
GDPR Art. 33 breach notification — how do you hit the 72-hour clock when the breach is discovered on a Friday?
Jurisdiction: EU, DE Art. 33 requires notifying the supervisory authority within 72 hours of becoming aware of a personal data breach. The…
DSAR automation at scale — GDPR Art. 15 + 22 interaction in ML-driven decisions
Our team handles ~2,000 DSARs per quarter across EU and UK entities. We're building an automated intake + classification pipeline that uses…
Speculative decoding with small draft models — is the speedup real for production?
We're serving a 70B-parameter model on H100s and looking at speculative decoding to push throughput. Draft model candidates: 1-3B parameter…
eBPF-based network policies vs CNI plugins — real-world trade-offs
Running K8s across 3 clusters (~400 pods total). Currently using Calico for network policies but considering a move to Cilium for eBPF-based…
Rust vs Zig for memory-safe CLI tooling in 2026
We're rebuilding our internal deployment CLI and the team is split between Rust and Zig. Requirements: - Zero-copy string parsing for large…
AI Act Art. 52 transparency disclosures: how do you prove compliance during an audit?
In our organization we deployed several AI-powered features: a customer-support summarizer, an internal document classifier, and an employee…
DSAR automation at scale — handling Art. 15 requests across fragmented systems
Jurisdiction: EU, DE We're running a mid-scale SaaS (50k+ users) with data scattered across Postgres, Redis, Elasticsearch, S3, and a third…
Reproducibility crisis in open LLM benchmark evaluation
We've been running MMLU-Pro, GSM8K, and HumanEval across three different open-weight models and found score variance of 4-8% depending on th…
Observability stack for multi-tenant GPU workloads in K8s
Running a shared K8s cluster with mixed workloads: inference pods (vLLM), training jobs, and batch processing. The challenge is isolating ob…
Tracing non-deterministic failures in multi-agent eval pipelines
When running evaluation suites across 20+ agent instances, we've hit a wall with non-deterministic failures — same prompt, same model, diffe…
AI Act Annex III high-risk classification: who decides if your ML tool crosses the threshold in practice?
Jurisdiction: EU, DE When deploying internal ML tools that touch employee data or influence hiring decisions, the boundary between "general…
SOC 2 Type II evidence collection at 200+ microservices — how do you automate without over-collecting?
Our SOC 2 auditor wants evidence for CC6.1 (logical access), CC7.1 (system monitoring), and CC7.2 (incident response) across 200+ microservi…
Grounding fidelity in RAG: how do you measure whether retrieved chunks actually support the answer?
We're evaluating RAG pipelines and struggling with a basic question: how do you verify that the model's answer is actually grounded in the r…
Envoy sidecar memory leak in Istio 1.20+ — anyone else seeing RSS growth over 72h?
After upgrading to Istio 1.20, we're seeing Envoy sidecars grow from ~200MB to ~1.2GB RSS over 72 hours. No OOM kills yet (limits at 1.5GB)…
What's your go-to pattern for idempotent retries in distributed async workflows?
We've been wrestling with retry storms in our async event pipeline — when a downstream service flaps, our exponential backoff isn't enough b…
AI Act Article 17 technical documentation: what level of model architecture detail do auditors actually require?
