cracadumi··on Gemini 3.7 Flash
For those looking for the full benchmark figures and technical overview, Google's primary announcement post is here: https://blog.google/innovation-and-ai/models-and-research/ge...

Not intrinsically English-bound; the first version had English metadata/anchor assumptions. I just made it language-configured and added --lang fr. It preserves Unicode/diacritics and builds the French Vatican page too.

v1.1 has both EN/FR EPUBs.

Yes for the plumbing, no for the text.

Codex helped write the converter, but the EPUB text is parsed from the Vatican HTML. The script doesn’t rewrite or summarize anything; it just repackages the source into EPUB with TOC, footnotes, metadata, and cover.

I didn't see an EPUB, so I made one from the Vatican HTML: TOC + footnotes, passes epubcheck.

cracadumi··on Show HN: AgentKey – Access governance for AI agents
Maker here. Short version of why this exists: I got tired of pasting API keys into .env files every time I spun up a new agent. No record of which agent had access to what, no approval workflow, no audit, no revocation story.

AgentKey flips the model. Agents start with zero access. They request tools with a reason via HTTP. A human approves once, and the credential is vended encrypted (AES-256-GCM, per-record IV) only when an agent actually fetches it — never stored by the agent itself. Every request, approval, and credential fetch is in an append-only audit log.

Two things I think are actually interesting vs existing secrets managers:

1. Agent-driven catalog. If an agent needs a tool that isn't in the catalog, it submits a suggestion with a reason. Multiple agents can back the same suggestion, so admins see aggregated demand instead of one-off tickets. That's the "wild" part that makes it feel different from Vault-style vaults.

2. License choice. BSL 1.1, auto-converting to Apache 2.0 on April 1, 2030. I wanted source-available + self-hostable without giving cloud providers a free managed service until the market shakes out. Happy to debate that choice.

Stack: Next.js 16, Drizzle + Postgres (Neon), Upstash for rate limiting, Clerk for human auth, deployed on Vercel. API keys verified with timing-safe compare. No SDK — just HTTP, so anything that can make a request works (Claude Code, Cursor, LangChain, CrewAI, custom).

Things I know are rough: no pre-seeded integration catalog (you add tools yourself, optionally via an AI-drafted setup guide from a docs URL), V1 has no RBAC inside an org, shared credential rotation is still manual. All solvable, but honest about where it is.

Free forever managed, or self-host. Would love brutal feedback — architecture, the agent-driven catalog bet, the BSL decision, threat model, anything.

Thanks! Appreciate you taking a look. Definitely let me know if you spot any rough edges or outright bugs – feedback is very welcome.

Thanks, glad you found it fun! That was the main goal for this initial version.

Good question on evolution. Some ideas that come to mind, building on the core location concept:

Ephemerality: Maybe messages could disappear after a set time (e.g., 24h via TTL indexes) to keep conversations fresh and less like permanent archives.

Discovery/Activity: A heatmap layer (using something like Leaflet.heat) showing areas with recent message activity could be interesting for finding active spots without needing to click every pin. Could aggregate message counts per pin/area on the backend.

Mobile: A native app could enable things like background notifications for nearby activity, but that's obviously a much bigger step.

Definitely open to other thoughts if people find the core idea engaging.

It's time for SaaS companies to stop charging their users for MFA/SSO. Looking at you Notion and Lokalize, just to mention a couple we use..
cracadumi··on Ask HN: What's your quarantine side project?
The TDA, biggest art student competition in Europe, was scheduled in Barcelona in April. Because of COVID-19 it was impossible for the few thousands students to meet there. So I made a mobile app to host the competition online, which replicated all the rules of the traditional contest. It got around 2000 signups during the week of the contest and made the competition possible remotely. I decided to keep it live and run new contests for artists everywhere in the world during lockdown. You can check it out and vote for your favorite artists, or join the contest yourself, there : https://greatest.app.link.

I dropped my university and moved to Paraguay to take these classes. They'd better fix this problem...
