Durable Memory: Why Vector Databases Aren’t Enough

Part 3 of the Building the AI Memory Stack series After finishing Part 2, I noticed something. The browser tabs I had open while writing it were gone. The temporary notes were gone. The diagrams existed only while I was drafting. The article remained. That is the question underneath this entire post. Why did one Continue reading "Durable Memory: Why Vector Databases Aren t Enough" The post Durable…

The Build-Optimizer

(Orchestration and the Yield Calculator) We have scanned the geometry of the oak. We have etched the Digital Passports into the fiber. Our JSON-LD Store is now a high-fidelity map of every curve, width, and wine-stain in the workshop. But data alone does not build a chair. The final stage of the Master Woodworker series Continue reading "The Build-Optimizer" The post The Build-Optimizer appeared…

Material Provenance

(Agentic Memory and the Digital Passport) In moving into the workshop, we re working on a Material-CV tool which performs geometric audits. We know we have 280 staves and exactly enough wide material for four side tables. But in the Salvaged Barrel Studio, we don t just sell furniture; we sell a story. To do that, every Continue reading "Material Provenance" The post Material Provenance appeared…

The Master Woodworker

(Computer Vision and the Material Memory of Oak) The harvest is tucked away in the cellar, and the Willamette Valley is settling into its winter rains. In the vineyard, the work has slowed to a crawl. But in the Salvaged Barrel Studio, the tempo is just picking up. A trailer just arrived with ten neutral Continue reading "The Master Woodworker" The post The Master Woodworker appeared first on Blog…

Active Working Memory: The RAM of Agentic Systems

Part 2 of the Building the AI Memory Stack series When I published the first article in this series, I thought I was writing about context windows. The more I wrote, the more I found myself bouncing between documents. I had the glossary open in one browser tab. The Memory as Infrastructure article was open Continue reading "Active Working Memory: The RAM of Agentic Systems" The post Active Working…

The Resilient Farm

(The Final Gamble and the Zero-Waste Finale) The primary harvest is over. The bins are mostly empty and the air in the cellar is thick with the smell of fermentation. In a traditional vineyard, this is where the data collection stops. But in The Agile Harvest, the final 5% of the season is where true Continue reading "The Resilient Farm" The post The Resilient Farm appeared first on Blog of Ken W.…

The Context Window Isn’t Memory. It’s the CPU Cache of AI.

Treating the context window as memory is one of the most expensive misconceptions in AI systems design. This piece reframes it as CPU cache and maps the full memory hierarchy that has to live beneath it. The post The Context Window Isn t Memory. It s the CPU Cache of AI. appeared first on Blog of Ken W. Alger .

The Supply Chain Guardian

(Provenance, Logistics, and the Unbroken Chain) Our last post on a Pivot Engine identified a 96 hour window to move 20 tons of Riesling into the culinary market. The decision is made and the tractors are out. But as soon as those grapes leave your gate, they usually become a nameless number on a bill Continue reading "The Supply Chain Guardian" The post The Supply Chain Guardian appeared first on…

The Pivot Engine

(Connecting the Local Twin to the Global Market) In our last post, we built the Digital Twin of the dirt. We gave our vineyard blocks a permanent identity and a way to log real-time sugar and acid levels. But a Digital Twin is just a mirror; to survive a lopsided season, you need an Engine. Continue reading "The Pivot Engine" The post The Pivot Engine appeared first on Blog of Ken W. Alger .

The Agent Tool-Calling Pattern

Pattern Defined Precise Definition: Agent Tool-Calling is an inference pattern where the model is provided with a set of executable function schemas (tools), allowing it to bridge the gap between text generation and structured action by outputting a valid JSON object for external execution. Problem Being Solved Natural language is inherently fuzzy, but APIs are Continue reading "The Agent…
