A binary instruction format for a stack-based virtual machine that executes code at near-native speed across all major browsers.

WebAssembly (Wasm) provides a high-performance compilation target for languages like C++, Rust, and Go, enabling complex applications—think AutoCAD or Google Earth—to run in the browser without plugins. It operates alongside JavaScript within the same security sandbox, utilizing a compact binary format that minimizes download times and maximizes execution efficiency. With support from the W3C and all four major browser engines, Wasm is the industry standard for bringing heavy-duty computational workloads to the web.

## Recent Public Talks and Demos

### [Here be Dragons -- agentic programming the hard stuff](https://durango.aitinkerers.org/talks/rsvp_MlGmL7fmWYg)

I made an operating system/kernel! We'll talk about pushing agentic programming solidly outside the mainstream, how well it deals with very demanding projects, what methods of guiding the LLM worked best for me, and how to approach projects that are neither one-shot nor vibecoding compatible. Demo: the kernel in a VM. We'll skim my Fable chat logs for studying and deciding software architecture, as concrete examples of how to form short to the point prompts that get results.

### [SaveSora: Downloading & Watermark Removal for OpenAI Sora Videos](https://dc.aitinkerers.org/talks/rsvp_zio-5LxaGn4)

SaveSora is a free web tool that breaks through OpenAI Sora's download restriction. Sora only lets you download your own videos — SaveSora lets you grab any publicly shared Sora video via link, view its original generation prompt, and remove the Sora 2 watermark automatically. No login, no fees, works in the browser instantly.

### [Recursive Language Model with Nix and wasm](https://columbus.aitinkerers.org/talks/rsvp_LDGNgq0ctYw)

My weekend project was to see if I could replace the python notebook REPL implementation with nix. Turns out it only made sense for the explorer to use predefined nix-shell functions. So that the model could still freely write code I later added a wasm sandbox to run generated code over the input data.

### [Securing Agent Swarms: Detection & Enforcement at the Tool Boundary (OpenClaw + Beyond)](https://nyc.aitinkerers.org/talks/rsvp_a6syk3sS0cc)

Agentic coding isn’t “one process on one host” anymore. It’s a swarm of local and hosted planners/coders/reviewers using tools that touch files, run commands, and egress to the internet. The security boundary isn’t the prompt; it’s the tool boundary where intent becomes action. In this session I’ll do a walkthrough of a practical “SDR” layer for OpenClaw-style workflows: - Policy enforcement on filesystem + command execution (path allow/deny, traversal hardening, safe defaults) - Network egress control (where requests can go, CONNECT/TLS sanity checks, blocking risky sequences) - Signed receipts / audit trails so you can replay, diff, and prove what actually happened during a run - A small demo of writing a policy and watching it block + record tool calls in real time
