5NF and Database Design

https://kb.databasedesignbook.com/posts/5nf/wikipedia-1.png
The traditional way of teaching fifth normal form (5NF) is confusing and unnecessary, and a more logical approach is to start with business requirements and create a physical table schema using a textbook table design strategy. Two patterns of physical table design follow naturally: the AB-BC-AC triangle and the ABC+D star pattern, both of which are fully normalized and do not require 5NF ...

The M×N problem of tool calling and open-source models

https://www.thetypicalset.com/static/og-image.png
Tool calling with closed-source models is seamless, but with open models, it depends on a wire format the engine must understand, leading to implementation burdens. A shared declarative way to describe wire formats is needed to standardize tool calling across models and engines.

The future of everything is lies, I guess: Work

The author warns that machine learning (ML) may lead to widespread job displacement, deskilling, and automation bias, potentially exacerbating wealth and power consolidation in the hands of large tech companies. The author fears that ML may not deliver on promises of abundance and instead lead to economic shocks, increased income inequality, and a loss of intellectual inheritance.

Show HN: A memory database that forgets, consolidates, and detects contradiction

Vector databases store memories. They don't manage them. After 10,000 memories, recall quality degrades because there's no consolidation, no forgetting, no conflict resolution. Your AI agent just gets noisier. YantrikDB is different. It's a cognitive memory engine — embed it, run it as a server, or connect via MCP. It thinks about what it stores. db.record("read the SLA doc by ...
