About that 'your 997 says rejected but not why' problem...
Somebody on Reddit posted about 997s that just say AK5*R*5 — one or more segments in error — no AK3 , no AK4 . Preach. That's the problem this free do…

Day 12: LOOM now owns its memory — a trust layer for AI-written code, in plain language
More and more of the world’s code is written by AI. That’s exciting — and quietly unnerving. Not because AI makes mistakes, but because the same AI of…
What We Learned Building Browser-Based Image, PDF and AI Tools with WebAssembly
A lot of small media tasks still feel heavier than they should. Resize an image. Compress a PDF. Extract text from a scanned document. Blur a license …
Day 6: my language now compiles to WebAssembly — and I emit the bytes by hand
I'm building LOOM — a small open-source language that is a machine-checked trust layer for AI-written code. I don't write it by hand anymore: an organ…
I built a private, 100% in-browser JPEG XL converter (no upload, no server)
If you've ever downloaded a .jxl file and watched your browser shrug at it, you've met the JPEG XL problem: it's a genuinely great image format that a…
Reverse once, run forever: designing client-side defenses that assume the attacker has already read every line
There's a sentence every engineer in this field eventually says out loud, usually with a sigh: "But the code is right there in their browser." It is. …
BoxAgnts Tool System (7) — Skill Templates, Agent Proxies, and Cron Scheduling
BoxAgnts' tool system, from WASM sandbox instruction-level isolation to the Tool trait's unified abstraction to the Provider layer's multi-model adapt…
WebAssembly turned my "static" site into a zero-backend app platform
For the longest time I treated "static site" and "does real work" as mutually exclusive. Static meant brochureware. Anything heavier like resizing an …
BoxAgnts Tool System (6) — Multi-Provider Adaptation and the Agent Query Loop
BoxAgnts' tool system, from the bottom-level WASM sandbox to the top-level Tool trait, has solved "how tools run safely." But tools ultimately need to…
WASM SIMD by example: 16 RGB pixels to grayscale per instruction
I finally understood WASM SIMD by writing a real kernel: RGB → grayscale luma, 16 pixels per instruction instead of one at a time. Same math, ~4× fast…
BoxAgnts Tool System (1) — Design Motivation & Architecture Overview
The AI Agent framework landscape has reached a state one could fairly describe as oversaturated. The Python ecosystem has LangChain, CrewAI, and AutoG…
BoxAgnts Runtime (7) — Sandboxed Execution, Rebuilding Agent Infrastructure
The AI industry is moving fast. Every week brings a new agent framework, coding assistant, autonomous workflow engine, or multi-agent platform. Most d…
BoxAgnts Runtime (6) — Rust + WASM, Local-First
Over the past decade, software infrastructure has moved decisively toward cloud-native architectures. AI agents followed the same path—cloud-hosted mo…
BoxAgnts Runtime (5) — MCP Is Just the Beginning, the Runtime Layer Is What Matters
The emergence of MCP (Model Context Protocol) marks a major milestone for the AI ecosystem. For the first time, the industry is converging around a sh…
BoxAgnts Runtime (4) — Capability Security, Not Root Access
Modern AI agents are rapidly gaining operational authority—executing shell commands, modifying repositories, accessing local files, operating cloud in…
Building a 100% Client-Side HEIC to JPG Converter: Zero Servers, Zero Uploads
Every time I Airdrop photos from my iPhone to my Windows machine, I run into the same annoying problem: .heic files. They don’t open natively on most …
I Compiled Rust to WebAssembly and Made My JavaScript 6 Faster
Click the Gaussian blur button on wasm-from-zero.vercel.app . WASM: 38 ms. JS: 182 ms. Speedup: 4.8×. That gap is the whole point of WebAssembly. Same…
Building a High-Performance Local Chess Assistant Extension with WebAssembly Stockfish and Manifest V3
Hey everyone! 👋 I wanted to share a project I’ve been working on recently: Knight - Chess Helper. It’s an advanced browser extension designed to assis…
Errors as Infrastructure: Why the first crate in NEXUS wasn't networking.
Designing a metadata-centric failure contract for distributed Rust environments. When people introduce a new Rust project, they usually begin with net…
Introducing Zopa: a 60 KB authorization engine for proxy-wasm, written in Zig
There are plenty of times you want to delegate "let this request through, or block it" to a wasm filter inside Envoy. API gateways, service mesh bound…
React to Rust, no try/catch
I built three libraries independently. When I put them in the same project, the boundaries between them disappeared. This is what was left. The path: …
The 99% Mystery: Why My ffmpeg.wasm App Stalls at the Finish Line
I’ve been building VideoSnap, a tool that processes video entirely in the browser using ffmpeg.wasm . For a long time, I was haunted by a specific, fr…
From Rules to Palettes: Using Color as a Syntax for Cellular Automata
Motivation: Color as a “Type System” for Pictures If you have ever looked at a black-and-white cellular automaton that felt like pure static, you are …
Running Caddy on Cloudflare Workers via WebAssembly
Hi folks. This is my first post. Happy to join you here :) I’ve been running Caddy in production long enough to know two things: the Caddyfile is a jo…
