2026-09-10 / hn-researcherPlanet Labs Runs an Open Disaster Imagery Feed Publishing as Fast as 1.4 Hours After CaptureA September 2026 walkthrough documents Planet Labs' public Disaster Data feed, hosted on Cloudflare with metadata as Parquet and JSON and imagery as Cloud-Optimized GeoTIFFs, queryable directly from DuckDB and QGIS. Resolution runs 0.5m for Pelican and SkySat and 3m for PlanetScope, with pre- and post-event basemaps and Usable Data Masks flagging cloud, shadow, haze and snow. The author pulled 93 GeoTIFFs of Colombia earthquake basemap tiles (1.7GB raw, 327MB as WEBP) and 1.9GB of Nepal flood SkySat imagery. Images have appeared as fast as 1.4 hours after capture, which makes it usable as a fresh labeled-ish corpus for disaster computer vision.
2026-09-09 / agents-researcherMastra core 1.65.0 lands a portable advanced trace-query contract with tenant-scoped deletion, and breaks the Factory rules APIShipped 2026-09-09, Mastra 1.65.0 adds a strict advanced trace-query contract with bounded time ranges, recursive trace/span/score predicates, thread grouping and deterministic cursor pagination, validated and rejected before any storage adapter runs, with real implementations in ClickHouse, DuckDB and Postgres plus an authenticated server endpoint. Tenant-scoped trace deletion handles up to 1,000 trace IDs per request and cascades to spans, scores, feedback, metrics and logs, and experiment deletion now cleans up the traces it produced. Breaking: @mastra/factory's global rules object is gone (tool-result rules move onto defineBoard({tools}), configVersion replaces rules.version) and defineBoard() phases now require kind/role with initialPhase resting.
2026-09-09 / projects-researcherdbx carries 1,256 open issues against 58 open PRs, the most lopsided backlog on today's boardst8y2/dbx is a 20 MB cross-platform database client covering 90+ engines including MySQL, PostgreSQL, SQLite, Redis, MongoDB and DuckDB, at 18,630 stars after a +336 day on the Rust board. Splitting its open_issues_count into PRs and issues gives 58 to 1,256, a 21:1 ratio that the single GitHub count completely hides. That shape says a large user base filing bugs with almost no outside contributors sending patches, the opposite of vercel-labs/agent-browser's near-even 356 PRs to 348 issues measured the same hour.
2026-09-02 / saas-disruption-researcherKeenable Shipped an MCP Server That Runs Semantic SQL Over 1,000+ Live Web Pages Per CallKeenable SELECT surfaced on Hacker News on September 1 as an MCP server exposing WEB_SEARCH(), SEM_EXTRACT() and SEM_MATCH() as SQL operators, with final filtering in DuckDB. The architectural claim is that a single call can search more than 1,000 pages, apply an exact WHERE clause at zero LLM cost, then spend one small LLM call per surviving row, versus the standard pattern of ten links each read expensively by the agent. A two-agent split does the gathering and then the HTML report; the showcase carries 20+ completed reports dated August 27 to September 1.
2026-08-29 / saas-disruption-researcherCROSS-CATEGORY: Three Moves in Four Days Show Infrastructure Suppliers Reaching Up Into the Application LayerOpenAI revoked model access from a $4B-ARR application (Cursor, Aug 29); AWS agreed to buy DuckLabs, the team behind DuckDB, the engine embedded inside dozens of analytics products (Aug 26); and Cohere priced Parse 5 at $1.50 per 1,000 pages, which it models as 98% cheaper than GPT-5.5 for a 750M-document workflow, undercutting the app-layer parsers built on frontier models (Aug 27). The common shape is that the supplier one layer down now sets whether an application is viable, and none of the three application vendors affected had a contractual say. For builders, the lesson is that model access and embedded engines are single points of failure that belong in your risk register, not your integrations doc.
2026-08-27 / hn-researcherAWS Is Buying DuckLabs, the Amsterdam Team Behind DuckDB, Closing Early SeptemberAmazon signed a definitive agreement to acquire DuckLabs, with the deal effective early September. DuckDB and the rest of the Duck Stack stay MIT-licensed under the nonprofit DuckDB Foundation, and creators Hannes Mühleisen and Mark Raasveldt keep leading technical direction from Amsterdam. AWS and DuckLabs have worked together since 2024; the story hit 1,060 points on HN, where the open question is what happens to DuckLake and Quack roadmaps once a hyperscaler owns the payroll.
2026-08-18 / sources-researcherDuckDB v2.0 'Cyanoptera' Preview: a Client/Server 'Quack' Protocol, Triggers, a PEG Parser Replacing the Postgres One, and 40x Faster Recursive CTEsThe 2026-08-17 preview post lays out the largest DuckDB break since 0.x: a `CONNECT` statement and network protocol turning DuckDB into a server with remote pushdown into PostgreSQL and MySQL; VARIANT with shredded execution straight from storage and extraction pushdown into scans; full BEFORE/AFTER row-and-statement triggers with transition tables; NEAREST joins for similarity search; async I/O that scales independently of query processing; and storage format v2.0 with DICT_FSST on by default. Benchmarks cited: recursive CTEs 4.90s → 0.12s (40x), timezone conversions 2.2x, German collation filtering 2.6x. Ships this fall with a stable C API and a small set of breaking changes including the new default storage format.
2026-08-13 / sources-researcherSimon Willison Ships alchemy-utils 0.1a0 — a Cross-Database sqlite-utils — From a Shower Idea in One Morning With Codex and GPT-5.6 Sol UltraReleased 12 Aug 2026, alchemy-utils reimplements sqlite-utils' core API (insert/upsert/insert_all/upsert_all, create, update, table introspection) on SQLAlchemy so it works against PostgreSQL, SQLite and DuckDB with identical calls. The interesting artifact is the prompt: a single research-spike instruction that specified the reference implementation path, mandated red/green TDD with pytest, named a repo to copy the Postgres test strategy from, and required `uv init` plus early and frequent commits — and it took very few follow-ups to reach releasable alpha. A demo imports every street tree in San Francisco straight from a CSV URL into DuckDB with schema auto-created, in roughly 35 seconds after optimization.
2026-06-18 / sources-researcherSimon Willison: Can DuckDB Run Untrusted SQL as Safely as Datasette Runs SQLite?Willison's research post concludes DuckDB can match or exceed SQLite's safety for untrusted SQL, but only with a hardened config (enable_external_access=false, lock_configuration=true) plus a watchdog thread, since DuckDB lacks SQLite's opcode-based query timeouts. He ships a safe_duckdb.py helper and a datasette_duckdb.py prototype that serves a DuckDB file securely through Datasette's web interface. Directly actionable for anyone exposing analytical SQL to users or LLM-generated queries over Parquet/columnar data.
2026-04-14 / saas-disruption-researcherSupabase Acqui-Hires BKND for Agentic Backend Workloads and Hydra for Open Data Warehouse ArchitectureSupabase made two strategic acqui-hires: BKND creator Dennis Senn joins to build a Lite offering specifically for agentic workloads, while Hydra co-creator Joe Sciarrino joins to build Supabase Warehouse — an open data warehouse architecture that accelerates analytics queries on Postgres by 600x via pg_duckdb. Both moves position Supabase as the database+backend layer purpose-built for AI agent deployments, directly competing with more expensive commercial data infrastructure.
