RTO and RPO for Data Platforms: Test the Recovery Path
RTO and RPO are measurable recovery objectives, not labels on an architecture diagram. Build a failure matrix and test the complete recovery path.

Object Storage for Data Platforms at Scale
Size an object store against bytes, object metadata, request demand and maintenance time. A practical worksheet for small files, retention, erasure coding and release-channel choices.

Benchmark Best Practices, Part 2: Little’s Law Ties Throughput, Latency and Concurrency Together
Second in my benchmark best practices series. Little’s law checks that throughput, latency and concurrency describe the same system, exposes the load generator’s ceiling, and turns a latency budget into a sizing requirement.

MinIO delete-marker convergence: how the Silo fork fixed the 405 replication loop
The 405 storm had three root defects in the delete-marker path. PR #162 fixed the first attempt; PR #184 fixes retries, purge status and MRF healing in the Silo fork.

MinIO Community in Production: Assess the Risk You Are Running
MinIO Community Edition has had no release since October 2025 and the repository is archived. Three CVEs will never be patched there. Here is how to assess what your cluster is actually exposed to, and where the maintained community fork fits in.

Your AI Supply Chain Is a Production Dependency. Audit It Like One.
Two movements meet: AI is getting production responsibilities, and production data is flowing through AI. Anthropic’s September report, malicious routers, training data provenance and model drift show what to verify before an AI reaches production.

MinIO site replication bug: how 684 million HTTP 405s exposed the delete-marker loop
HEAD probes on delete markers answer 405 and replication counts that as success. 20M stuck versions turned the loop into 684M useless requests in 48 h.

Vibe Coding, CS Knowledge, and DHH’s Claim
A study of 100 students linked both CS knowledge and writing to vibe coding performance. I unpack the statistics, DHH’s claim and a practical way to test agent workflows.

Efficiency Is Not Raw Power: Meet GPT-6-Astra and the DeepSWE Reality
GPT-6-Astra XHIGH sits alone on the DeepSWE cost-performance frontier, and an older model beats a flagship tier. Follow-up: DeepSeek V4.1 Flash hits 98% of Astra’s score at 1.4% of the cost.

MinIO Replication Drops Objects Into a Counter Nobody Reads
During a MinIO replication incident three of the signals you reach for mislead you. The 405 on HeadObject is the success path, a retried 429 is invisible, and worker queue overflow logs nothing under the default priority. The counter that tracks dropped objects is incremented in four places and read in none.
