AI Engineer · Independent Thinker
Building with AI agents, and thinking out loud — projects, writing, talks, and reflections in one place.
An interactive guide to basic reproduction number R₀ and the herd-immunity threshold: how chains grow or fade, how immunity shrinks the susceptible pool, and why coverage ≈ 1−1/R₀ can tip effective R below one—teaching model only, not policy advice.
Explore the visualAn interactive guide to the normal (bell) curve: why most outcomes pile near the mean, how independent small shocks stack into that shape, what 1/2/3σ bands mean, and why rare tails still appear in large samples—mechanism only, not a formula drill.
Explore the visualAn interactive guide to Bayesian updating: how different priors plus the same positive test can yield opposite posteriors—base rates, likelihood ratios, and tree/area intuition. Teaching numbers only; not a medical diagnosis.
Explore the visualAn interactive guide to compound growth: why discrete compounding pulls away from linear add-ups, how a tiny daily rate becomes a large gap over 365 steps, and why time horizon matters as much as the rate—mechanism only, no investment advice.
Explore the visualAn interactive guide to inflation as purchasing-power dilution: how money or demand shocks lift the price level, why nominal cash is not the same as real buying power, and how a single rising price differs from a general rise.
Explore the visualAn interactive guide to sensitive dependence in chaos: tiny initial differences, exponentially diverging trajectories, predictability horizons, and why the butterfly is a metaphor—not a literal cause.
Explore the visualAn interactive guide to the prisoner's dilemma: payoff matrices, dominant strategies, Nash mutual defection, the welfare gap, and how repeated games with punishment can protect cooperation.
Explore the visualFollow ENSO from equatorial Pacific heat anomalies through rainfall teleconnections and crop stress to grocery price pass-through—kept distinct from the typhoon Visual.
Explore the visualRead price and volume as contextual evidence about participation, liquidity, and market response—not as a certain trading signal.
Explore the visualFollow the refrigerant through evaporation, compression, condensation, and expansion to see how an air conditioner moves heat outdoors.
Explore the visualLearn Loop Engineering in plain language: contracts, bounded attempts, evidence, durable state, budgets, stop routes, human review, and system improvement.
Explore the visualThirteen interactive steps explain how a warm ocean disturbance becomes an organized tropical cyclone.
Explore the visualAnthropic says Claude found ART (array-associated reverse transcriptases) under high-level direction. This post cross-checks the news post and technical report: search discovery vs unknown function, reproducibility limits, research-agent pipelines, and how builders should read the story.
OpenAI launched GPT-6 Sol and Luna on 2026-09-22: 50% lower API prices versus GPT-5.6 promo rates, with Astra-generation capability and alignment gains. Pricing, benchmarks, caching, and the Astra/Enigma side story—for coding-agent routing.
Anthropic launched Claude Opus 5.5 on 2026-09-22: about 40% lower cost on typical workloads versus Opus 5, with Fable-tier capability claims and matching safeguards. A builder-focused read of pricing, benchmarks, and coding-agent fit.
arXiv:2609.27678 compares Jev and nine hosted/local models on ContractNLI: cost, latency, baseline accuracy, and All-12 persistent correctness rank differently. Close means can hide flips—select on persistent correctness, not accuracy alone.
A practical teardown of alibaba/open-code-review: deterministic engineering owns file selection and positioning; the agent owns deep reasoning. Covers AACR-Bench, delegation mode, CI hooks, copyable patterns, and limits.
A teardown of cloudflare/security-audit-skill: Skill distribution, six audit phases, confirmed / needs_validation / rejected verdicts, adversarial validation, and fail-open behavior without a sandbox—plus install steps and enterprise limits.
A teardown of affaan-m/ECC—how Skills, Hooks, Instincts, Memory Vault, and AgentShield tackle performance, memory, and security; what actually plugs into Claude Code/Codex/Cursor; what enterprises can copy versus roadmap hype.
A deep read of arXiv:2609.26760 Growing Harness—turning recurring control into executable code via task feedback—contrasted with “just stuff more context” and with in-site harness / Skills / deterministic-pipeline narratives.
A viral YouTube clip ties Jev to Claude Code, but Jev cannot be the CLI chat model. This post covers the official skill, boundary hooks, MCP, and per-turn routing, contrasts NobodyWho’s 25-line minimal build, and discusses OpenAI fast-follow pressure.
A deep-dive technical guide into Xiaomi MiMo-v2.6 reinforcement learning training metrics, categorizing 2000+ metrics across Actor, Critic, DynSam, Timing, and tracing dashboard notifications to hard data evidence.
A source-backed look at Jev through TypeSafe's writing, developer experiments, and awesome-jev projects: browser actions, model routing, triage, citation checking, context management, and deployment boundaries.
A practical, evidence-based guide to Cordis, spatiotemporal composability, revertible effects, reactive coeffects, plugin lifecycles, and the architecture of DeepSeek Harness.
