What I observed over a year of French electricity load, with interval coverage and not only the mean error, then rebuilding a router between the two on 50 series.https://gwils28.github.io/en/posts/agents-code-vps/Tue, 03 Nov 2026 00:00:00 +0000https://gwils28.github.io/en/posts/agents-code-vps/A CPU VPS dedicated to the agent, reachable only over a private network, a separate production machine and GPUs rented by the hour: the state of play on 31 October 2026, from isolation to secrets and costs.https://gwils28.github.io/en/posts/claude-code-methode-revisee/Thu, 29 Oct 2026 00:00:00 +0000https://gwils28.github.io/en/posts/claude-code-methode-revisee/The lever is no longer the prompt but the context: what goes in, when, and what is handed to mechanisms that do not depend on the model. My method, revised as of 29 October 2026.https://gwils28.github.io/en/posts/impact-causal-series-temporelles/Tue, 27 Oct 2026 00:00:00 +0000https://gwils28.github.io/en/posts/impact-causal-series-temporelles/A counterfactual is a forecast. What I observed building one by hand, measuring its coverage on 100 panels with a known truth, planting four violations of the design, and applying it to Volkswagen’s share price after dieselgate.https://gwils28.github.io/en/posts/frequence-reentrainement/Sat, 17 Oct 2026 00:00:00 +0000https://gwils28.github.io/en/posts/frequence-reentrainement/Accuracy, freshness and stability don’t call for the same retraining frequency. What I observed on a ten-policy bench, an analytical model, the Monash electricity data and a causal simulation.https://gwils28.github.io/en/posts/reconciliation-hierarchique/Tue, 06 Oct 2026 00:00:00 +0000https://gwils28.github.io/en/posts/reconciliation-hierarchique/MinT guarantees coherence, not accuracy, and not calibration. Shown through theory, simulation, French grid data and count sales.https://gwils28.github.io/en/posts/claude-code-data-science/Tue, 29 Sep 2026 00:00:00 +0000https://gwils28.github.io/en/posts/claude-code-data-science/A fast-coding agent doesn’t replace method. How I work with Claude Code: context as the scarce resource, verification as the one non-negotiable step.
