- ECErlywarn, Clever Uptime Monitoring. Any thoughts?2011 · ▲11
We launched an early version of our uptime monitoring service Erlywarn to the public this week. http://erlywarn.com The project was scratching an itch that monitoring services would only alert you if your site went down and not if they started responding slowly or erratically. So we built Erlywarn to keep track of the response times and allow it to send notifications if your site responds unusually, as this is often an early warning sign that something is starting to go wrong.

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…
