Change an input. See what follows.
Explore a few systems ideas without setting up a cluster. Predict what will happen, step through the model, and inspect the result.
KV Cache Visualizer
Trace the relationship between model geometry, context, concurrency, and memory. Inspect logical bytes and rounded block allocation.
Open experiment →Distributed Systems Playground
Explore a consistent hash ring, delay replication, fail a node, and test quorum overlap. Every action is deterministic.
Open experiment →Linux & Networking Lab
Follow a simplified outbound packet path and compare local versus remote NUMA access using explicit hypothetical costs.
Open experiment →These are simplified, local, browser-based teaching models, not live clusters, kernels, or inference engines. Each experiment states its assumptions and separates calculation logic from presentation.
Built to be questioned.
Reproducible
The same inputs and action sequence produce the same state. Wall-clock time changes playback, not the result.
Inspectable
Formulas, units, and simplifications sit next to the visualization. No mystery numbers.
Local by default
Experiments run on your device. No account, external model API, or uploaded inputs.
