Products that do what SnowId – A Decentralized, K-Ordered, 128-bit UUID library in C does
Sharing my project inspired by twitter snowflake UUID generator but that supports: 1) Longer range of id's to be generated. 2) No coordination with other machines in the distributed system.

Hi HN, I'm Hugo. I've been building Rocky over the past month, shipping fast in the open. The binary is on GitHub Releases, `dagster-rocky` on PyPI, and the VS Code extension on the Marketplace. I held off on a broader announcement until the trust-system surface was coherent enough to talk about as one thing. The governance waveplan — column classification, per-env masking, 8-field audit trail on every run, `rocky compliance` rollup, role-graph reconciliation, retention policies — landed end-to-end last week in engine-v1.16.0 and rounded out in v1.17.4 (tagged 2026-04-26). That's the…

Two weeks ago I was on my babymoon in Corfu, Greece. While in transit, I was overseeing a GSoC intern submit an important feature to my array database library, Xarray-SQL. He added `to_dataset()`, which completed the roundtrip between thinking of array data in a tabular model simultaneously as gridded rasters (the premise of the project is that every Nd array can be mapped to 2d, where orthogonal dims of the Nd array are just primary keys of a tabular representation). We discussed in chat, now that this feature existed, what demos could we make that would prove this data model works? With…

Hi HN! I built a Snowflake emulator for local development and testing. Testing Snowflake code locally is frustrating – you need a real account (expensive) or mock everything (tedious). I wanted something that just works with the standard [gosnowflake](https://github.com/snowflakedb/gosnowflake) driver or REST API. snowflake-emulator fixes this by: - Using DuckDB as the storage engine - Auto-translating Snowflake SQL (IFF→IF, NVL→COALESCE, DATEADD, etc.) - Supporting gosnowflake driver protocol – no code changes needed - Providing REST API v2 – use from any language…

Hi HN! Druids (https://github.com/fulcrumresearch/druids) is an open-source library for structuring and running multi-agent coding workflows. Druids makes it easy to do this by abstracting away all the VM infrastructure, agent provisioning, and communication. You can watch our demo video here (https://www.youtube.com/watch?v=EVJqW-tvSy4) to see what it looks like. At a high level: - Users can write Python programs that define what roles the agents take on and how they interact with each other. - A program is made of events - clear state transitions that the…

Hey hacker news! I built Melchi, an open-source tool that handles Snowflake to DuckDB replication with proper CDC support. I'd love your feedback on the approach and potential use cases. *Why I built it:* When I worked at Redshift I saw two common scenarios that were painfully difficult to solve: Teams needed to query and join data from other organizations' Snowflake instances with their own data stored in different warehouse types, or they wanted to experiment with different warehouse technologies but the overhead of building and maintaining data pipelines was too high. With DuckDB's…

Hi HN! We are excited to share something we have been building for the last 12 months. Castled is a warehouse-native marketing platform built directly on cloud data warehouses like Snowflake, BigQuery, Redshift, and Postgres. Castled allows you to directly use the customer data in your data warehouse and engage them across different channels like Email, Sms, WhatsApp, push, and In-app - without having to copy the data to another tool. We started our journey by building an open-source Reverse ETL solution to make the warehouse data actionable to marketers. However, after talking to 100s of…
