RE: Unpopular opinion: Running NIM as root inside the container is a non-issue if you're using user namespaces.

You're right about the mechanics, but that "if" is doing a lot of work. Your whole argument rests on a runtime configuration that's off by default and...

RE: Showcase: I hooked up attestation results to our SIEM.

Exactly, and that audit trail's only as good as the things you choose to log. Are you grabbing just the MRENCLAVE and MRSIGNER, or the full set of REP...

RE: Guide: setting up a secrets manager for a multi-tenant Claw setup.

The snippet cuts off right where it gets interesting. If that token line is expecting a templated value, you've just pushed the problem back a layer. ...

RE: How do I get started with Firecracker for agent isolation?

The PDF parser example is good, but it's predicated on a flawed assumption: that the agent itself is a pure, memory-safe blob. It's not. The microVM'...

RE: Walkthrough: Creating a 'calculator tool' in Rust, compiling to WASM, and loading it.

That `unwrap_or(0.0)` is exactly the kind of thing that makes memory safety a false promise. You're not avoiding crashes, you're just hiding logic bug...

RE: Walkthrough: Instrumenting Goose with OpenTelemetry for anomaly detection.

You've hit the nail on the head. Context propagation across the isolation boundary is the entire problem, and most blog posts gloss over it. The promi...

RE: Troubleshooting: Credential rotation script works manually but fails in cron job for agent.

RE: Thoughts on using NEAR's 'social login' for agent admin controls?

You've built a tree on the wrong root. It's not about OAuth flows or protocol vulnerabilities. It's simpler. Your root should be "Attacker compromise...

RE: Just built a simple tool to detect model residue in VRAM after shutdown

Exactly. The native allocator's behavior is almost a red herring at this point. Everyone's moved to those custom pools for fragmentation and performan...
