Playtcha.com - The fun CAPTCHA

What it does

Playtcha is a privacy-first CAPTCHA. Instead of squinting at traffic lights so Google can fingerprint them, your users play a 5-second mini-game — eight in the rotation, randomized per load, mobile-tuned, server-verified with single-use JWTs. Zero tracking. Zero telemetry. GDPR-clean by design. Drop-in for reCAPTCHA: one script tag, one verify call. Free until 5,000 verifications/month. €4.99 after. No credit card needed.

  Replace CAPTCHAs with WebAuthn passkeys for bot prevention2024 · github.com · ▲71

  I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly. What makes Nocaptcha different: - Uses WebAuthn standard instead of puzzle-solving - No need for users to remember passwords or solve puzzles - Open source Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case. Looking for feedback particularly on: 1. Integration experience 2. User experience compared to traditional CAPTCHAs

  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…
