    I’ve been a long-time Snowplow user and unofficial evangelizer. I have deep respect for its founders, Alex and Yali, who I met a few times. What made me fall in love with Snowplow was that it was unopinionated, gave access to raw event data, and was truly open source. Back in 2013, that changed everything for me. I couldn’t look at GA the same way again. Over the years, analytics moved into SQL warehouses driven by cheaper CPU/storage, dbt, reproducibility, and transparency. I saw the need for a democratized Snowplow pipeline and launched a hosted version in 2019. In January 2024,…

    Hi HN, we are building Tracecat (https://tracecat.com/), an open source automation platform for security alerts. Tracecat automates the tasks a security analyst has to do when responding to a security alert: e.g. contact victims, investigate security logs, report vulnerability. The average security analyst deals with 100 alerts per day. As soon as an alert comes in, you have to investigate and respond. An average alert takes ~30 minutes to analyze (and 100 x 30 min = 50 hours > one whole day) Lots of things get dropped, and this creates vulnerabilities. Many breaches can be…

    I've been obsessed for the past ~year with the possibilities of talking to LLMs. I built a bunch of one-off prototypes, shared code on X, started a Meetup group in SF, and co-hosted a big hackathon. It turns out that there are a few low-level problems that everybody building conversational/real-time AI needs to solve on the way to building/shipping something that works well: low-latency media transport, echo cancellation, voice activity detection, phrase endpointing, pipelining data between models/services, handling voice interruptions, swapping out different…
