Offsy — Fast Kafka tailing for devs
Inspect Kafka events without bloat
What it does
I built a lightweight desktop app for browsing Kafka topics because I got tired of opening heavy admin dashboards just to inspect a few events. Offsy currently supports live message tailing, JSON inspection, filtering/search and a lightweight desktop workflow for Kafka developers. It’s currently an early access macOS alpha and I’d genuinely love feedback from people working with Kafka regularly.

Hello Everyone! We built SQLFlow as a lightweight stream processing engine. We leverage DuckDB as the stream processing engine, which gives SQLFlow the ability to process 10's of thousands of messages a second using ~250MiB of memory! DuckDB also supports a rich ecosystem of sinks and connectors! https://sql-flow.com/docs/category/tutorials/ https://github.com/turbolytics/sql-flow We were tired of running JVM's for simple stream processing, and also of bespoke one off stream processors I would love your feedback, criticisms and/or…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
