THE INTERNET IS THINKING
Earlier sources: Databases
Databases organize information for storage and retrieval. Follow relational and nonrelational systems, query engines, indexing, replication, and operational tools; performance claims depend on workload and configuration.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗96 classified signals in the fourteen-day window. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Show HN: Minimal dbt-style SQL builds with DuckDB and Make ↗
"DuckDB and Make are all you need!" I love the ergonomics of dbt for building reproducible data pipelines with DuckDB -- particularly the ability to define output tables as individual `SELECT` queries and have them refer to each other -- but have always found the configuration and boilerplate excessive for the projects I work on. With the recent Rust rewrite of dbt Core, now seemed like a good time to consider the bits I actually need/use. Recent…

Database-driven IFC framework for digital twins of existing structures ↗
Industry Foundation Classes (IFC) is an open standard for representing geometric and semantic information in building information modeling (BIM), which is widely used to support the development of digital twins (DTs). However, IFC has limited capabilities for handling heterogeneous operational data, hindering the integration of DTs into workflows such as structural health monitoring (SHM). This paper presents a database-driven IFC framework that stores IFC models and semantic data in a structured database. The IFC representation is extended to incorporate SHM and inspection information, enabli…
Live window recorded . This is the ingestion observation time, not the publication or discovery date of each source.
How to assess evidence about Databases
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
