Riding Handwired in public
/handwired-in-public
I am learning Cheng Lou's Handwired, where a program is a fixed list of FP32 ops. Five widgets on a toy runtime: the ReLU step trick, both branches always run, the host loop, loops as fixed work, and training a threshold.
The Entropy Wall
/entropy-wall
Models can crack random things we never expected. I tested 25 of them, the 2,300 token functions they wrote, and a Math.random attack in the browser, then asked what Cloudflare's Wall of Entropy is for next.
Terraloop
/terraloop
Two tools that run long tasks on Cloudflare without babysitting them: a heartbeat (loops-yaml) that re-prompts the agent, and terrarium running each job and handing back a receipt. Everything else is one markdown file.
If You're Here, Who's Driving?
/whos-driving
Google and Cloudflare are aiming at 2029 for post-quantum migration. A short note about agents, cryptography, and checking who still has the wheel.
desk and living-artifact: Cloudflare-Backed Hardware with OTA
/built-in-reverse
Two tiny Cloudflare-backed devices. desk installs apps with git push. living-artifact updates its own firmware over Wi-Fi with signed releases and A/B OTA rollback.
Worker Loaders as a Place: Sandboxed Dynamic Workers
/worker-loaders
Notes on using Dynamic Workers as short-lived execution spaces with explicit bindings and egress controls.
Constraint Theory: A Quiz on Where Agents and Humans Differ
/constraint-theory
Twelve statements about agents and humans. The quiz asks where surface behavior looks similar and where the analogy breaks.
Correctness: Software Correctness Tools Compared
/correctness
Reference hub for software correctness tools across runtime verification, model checking, verification languages, SMT solvers, theorem provers, and verified artifacts.
Self: Two Tiny Cloudflare Loop Patterns
/self
Minimal repro for long-running loops on Cloudflare: a Durable Object alarm that re-enters the Worker, plus a Workflow draining the same KV queue.
Prompts Are Wishes: Why Executable Checks Beat Instructions
/prompts-are-wishes
A deja gate passed while allowing broken storage behavior. That moved my attention from instruction wording to executable checks.
Taste: Preference vs. Whether a Design Reaches Its Listener
/taste
A designer note about confusing personal preference with whether an interface, explanation, or prompt reaches its listener.
Liquid Primitives: Building on a Stream
/liquid-primitives
Notes from replacing runners, instructions, and implementations while keeping tests and behavior stable.
Ego-Less: Rebuilding Without Breaking
/ego-less
A personal note about receiving critique, watching code get rewritten, and separating the work from the feeling of being judged.
Compaction: What Survives When the Context Window Resets
/compaction
A 75-call GPT-4.1 experiment comparing five context representations across goals, files, conventions, corrections, and prior reasoning.
Effect-First: Benchmarking Four Approaches to Agent-Assisted Effect Code
/effect-first
Five GPT-5.2 tasks with regex judges comparing curated guidance, human documentation, raw source excerpts, and baseline.
Benchmarks, reference tables, literature reviews. Data-driven, no opinion.
System prompts, worker loops, orchestration patterns. Copy and use.
