I run local AI. Why do I care about S3?
Guided path from local inference to the S3 storage ecosystem — storage, formats, retrieval, and the tradeoffs that matter.
Architectural shifts as they happen. Each post anchors on a pre-existing pain point and walks through what changed.
Fine-Tuning an LLM on Your Own Data, Locally: What It Actually Costs in 2026
Fine-tuning vs RAG, QLoRA VRAM requirements from 7B to 70B, Unsloth vs Axolotl vs LLaMA-Factory, what catastrophic forgetting really does to a fine-tuned model, and which teacher-model licenses actually permit distillation. The complete decision path for training an LLM on your own data without shipping it to anyone — with the real hardware numbers.
When the Benchmarks Stopped Agreeing: Agent Memory's Trust Crisis Meets the Priced Cache
The same memory system scores 92.5% or 55% depending on who runs the benchmark. Meanwhile cached input tokens are being billed at zero and cache-hit-rate became a production SLO. July 2026 is the month agent memory's two crises — trust and cost — turned out to be the same story, and the seam between them is where the next incident lives.
Memory Became a Market: The AI Data Stack is Being Rebuilt on Three Fronts
In one week of July 2026: a benchmark war between agent-memory vendors with irreconcilable numbers, a second critical CVE in the most popular memory layer, a columnar format field fracturing into workload-specific successors to Parquet, and 3-bit KV-cache quantization getting its first independent reproduction. Underneath all three fronts, a 472% enterprise SSD price surge is forcing the whole stack onto object storage. The rebuild isn't coming — it's live.
Getting Data Into the Lakehouse — Choosing a CDC-to-Iceberg Path in 2026
The default way to move operational data into the lakehouse used to be a four-system pipeline: Debezium reads the database WAL, Kafka buffer...
48Choosing a Lakehouse Catalog — Polaris vs. Unity Catalog vs. Gravitino vs. Cloud-Native

19The Post-MinIO Landscape — Self-Hosted S3 Branches Out
For nearly a decade, "self-hosted S3" meant MinIO. It was the default answer — simple, fast, single-binary, open-source. The February 2026 a...
37Picking an AI Memory Layer in 2026 — Mem0 vs. Zep vs. Build-Your-Own
The shift from stateless LLM inference to stateful, multi-agent systems forces a decision that didn't exist two years ago: where does agent ...
