Control & Simulation

Follow a simulated drone from sensor outages to measured recovery and the failures that remain after a landing mitigation.

System
AeroLoop
A simulation-only drone laboratory measuring sensor-outage recovery and capture-aware landing. The retained stress studies report accepted: false, with replayable flight evidence and explicit failure boundaries.
Article
How Long Can a Drone Controller Fly Blind? Measuring Recovery From Sensor Outages
AeroLoop's retained simulation study recovers from 500 ms missing captures under the tested conditions. One- and two-second gaps expose a failure boundary that prediction and a landing guard do not close.
Engineering note
AeroLoop finds the edge of its sensor-outage envelope
500 ms profiles recover in the retained baseline study. One-second cases are mixed and all two-second missions fail. Later prediction and landing-guard studies still report accepted: false.

See how a Linux program talks to a simulated device, from sending a request to receiving a result.

System
Yocto + QEMU EDU Lab
A hands-on lab for building Linux images and learning how drivers communicate with simulated devices on two processor architectures.
Article
PCI Driver vs Platform Driver: What Changes Between x86-64 and ARM64?
Compare two explicit virtual-device contracts across discovery, MMIO, interrupts and evidence without confusing CPU architecture with bus type.
Engineering note
Independent PCI and ARM64 learning paths
Closed lab manifests now separate x86-64 PCI MSI/INTx and bounded DMA from an ARM64 Device Tree and platform-driver path. The ARM64 peripheral has its own hardware contract and does not expose DMA.

A reading path

See how an AI tool can change a 3D scene and check what it sees.

System
Cogniform
A 3D engine that lets software and AI tools change a scene, then inspect images and object data from the same scene version.
Article
An Observation Needs a World Revision
What Cogniform's revision-linked observations clarify about agent feedback, local transport and evidence.
Engineering note
Bounded local agent sessions
The CLI now documents inherited-stream sessions and a local MCP adapter for queries, imagination, atomic patches, and revision-linked observations. These adapters add no network listener or remote security boundary.

A reading path

Learn how recording inputs lets you repeat a game session and check the result.

System
LudoWeave Engine
A Python engine for small 2D worlds with verified replay, pause and single-step controls, seek/resume, and a tick-aware playback status panel.
Article
A Replay Is More Than a List of Inputs
How consumed input snapshots, world transactions and independent verification make a recording useful evidence.
Engineering note
Record play sessions, verify them headlessly
Clockwork Arena can record the input snapshots its play loop consumes and verify them in a fresh headless process. Recording is opt-in, capped at 3,600 requested ticks, and keeps rendering and audio outside the artifact.

A reading path

Follow a small system from startup to running programs with limited permissions.

System
MakopaOS
A small operating system lab for studying how a computer boots, runs isolated programs and controls access to resources.
Article
Where AI Fits in the Larger System
What recent work on agent standards, on-device inference, and reliability has reinforced for me about building AI into real products.
Engineering note
From boot sector to explicit kernel authority
The retained BIOS example is now accompanied by a freestanding Rust kernel and thin UEFI loader. Fixed workloads exercise task isolation, capability-mediated IPC, a bounded approval broker, and a supervisor-readable effect journal.
