Show HN: Multiplayer flight SIM over San Francisco using Google 3D Tiles

Built this over the weekend inspired by levelsio's viral flight sim last year. Uses Google's Photorealistic 3D Tiles for actual SF terrain - you're flying over real buildings.

Multiplayer via WebSockets. You can dogfight strangers over the Golden Gate.

Stack: Three.js and 3D Tiles Renderer.

Would love feedback on the flight physics - still tuning it.

Show HN: Nono – Kernel-enforced sandboxing for AI agents

Hey HN

Luke here.

I built nono and got it out quick then I expected, in response to the openclaw carnage, but its use is beyond openclaw.

The problem: AI agents execute code on your machine. Prompt injections, hallucinations, or compromised tools can read ~/.ssh, exfiltrate credentials, or worse. Application-level sandboxes can be bypassed by the code they're sandboxing.

I have been around security for a long old time now (i started something called sigstore a few years back) and have seen this pattern so many times before.

The solution pitch: nono uses OS-level isolation that userspace can't escape:

Linux: Landlock LSM (kernel 5.13+) macOS: Seatbelt (sandbox_init) After sandbox + exec(), there's no syscall to expand permissions. The kernel says no.

What it does:

nono run --read ./src --allow ./output -- cargo build nono run --profile claude-code -- claude nono run --allow . --net-block -- npm install nono run --secrets api_key -- ./my-agent

Filesystem: read/write/allow per directory or file Network: block entirely (per-host filtering planned) Secrets: loads from macOS Keychain / Linux Secret Service, injects as env vars, zeroizes after exec

Technical details:

Written in Rust. ~2k LOC. Uses the landlock crate on Linux, raw FFI to sandbox_init() on macOS. Secrets via keyring crate. All paths canonicalized at grant time to prevent symlink escapes.

Landlock ABI v4+ gives us TCP port filtering. Older kernels fall back to full network allow/deny. macOS Seatbelt profiles are generated dynamically as Scheme-like DSL strings.

Limitations:

macOS: Currently allows all reads to make executables work. Tightening in next release. Linux: Landlock doesn't cover everything (no UDP filtering until recent kernels, no syscall filtering - that's seccomp territory) No Windows support (yet?)

Origin:

Built this for OpenClaw (AI agent platform handling Telegram/WhatsApp messages). Needed real isolation, not "please don't read this file" isolation. Generalized it because every agent runner has this problem.

GitHub: https://github.com/lukehinds/nono Docs: https://docs.nono.dev Site: https://noto.sh

Apache 2.0. Would love feedback on the security model, especially from folks who've worked with Landlock or Seatbelt. Having said that, the code needs a good tidy and I am not exactly proud of it, so go easy on me!

Show HN: Bullstudio – BullMQ dashboard you run with npx

Hey HN!

I built bullstudio, a modern dashboard for BullMQ that you can run like Prisma Studio:

npx bullstudio -r <redis_url> → it starts a local web UI (default http://localhost:4000) and opens your browser.

Why I built it In BullMQ-heavy projects, I kept losing time answering the same questions: Which queues are unhealthy? What’s failing right now? Where is this flow stuck? I’d bounce between logs, Redis inspection, and ad-hoc scripts. I wanted a “start it in seconds” UI that’s easy to point at any environment.

What it does today

Overview: queue health + throughput/failure trends

Jobs: browse + filter/search, inspect payload/attempts/stack traces, retry failed jobs

Flows: interactive parent/child visualization with live state updates

Repo: https://github.com/emirce/bullstudio

What I’d love feedback on

What are your “must-have” ops features for BullMQ (stalled detection, worker liveness, read-only mode, alerts, etc.)?

Payload safety: what defaults do you expect (truncation, masking keys like password/token, etc.)?

For teams with many queues/environments: what makes a dashboard feel production-ready?

Happy to answer any questions or add missing features if there’s demand.

Ask HN: The Next Big OS Leap

After witnessing what is being said about the AI Botlers (like OpenClaw/Moltbot/Clawdbot), I believe UIs will start melting big time.

The point, click and type era is over.

Voice will take over as the primary interface.

UIs will be adaptive and enabled on demand.

There will be an AI agent layer on every single PC out there.

Since privacy will be an issue, "Shazam-like" filters will inhibit uncleared capture of voice.

Makes sense?
