Inbox Authority

What it does

A developer newsletter is one of the highest-leverage assets you can own, but most founders stall before issue #1. Inbox Authority is the complete system to go from zero to monetized in 30 days: platform setup (Beehiiv or ConvertKit), a 6-part welcome sequence, 12 weeks of issue templates, a growth playbook to your first 100 subscribers, and the rate card, pitch deck, and outreach templates to book sponsorships.

  Hello Inbox – Free email deliverability checklist for marketers2023 · helloinbox.net · ▲37

  After struggling with low open rates in my small lifestyle software business, I decided to go down the rabbit hole that is email deliverability, learned a bunch of things I didn't know even after being in tech for a decade. A/B tested a bunch of things and finally got good results. I then decided to put together a comprehensive checklist of everything I learned and got me results to share with others.

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
