Hamiltonian Neural Networks from a Differential Geometry Perspective The post explains Hamiltonian Neural Networks through differential geometry, showing why a normal MLP can fit motion data but still invent or lose energy over long rollouts. It shows that by learning a scalar Hamiltonian and deriving motion through the symplectic gradient, HNNs make energy conservation structurally unavoidable instead of hoping the network learns it from data. https://abscondita.com/blog/symplectic-sledgehammer-for-a-spring

Write a coding agent from first principles: better tools This tutorial builds on the coding agent you implemented in the tutorial “Write a coding agent from first principles”. In this tutorial, you'll take your agent and improve its capabilities by implementing the text edit and bash command tools that Anthropic provides. https://mathspp.com/blog/write-a-coding-agent-from-first-principles-better-tools

You shouldn't trust Trusted Publishing The post explains that PyPI Trusted Publishing is an authentication mechanism for machine-to-machine trust between CI/CD workflows and package registries, not a signal that a package is safe or high quality. It shows how Trusted Publishing reduces long-lived credential risk, while warning that users should not treat it like a “green checkmark” because malicious or low-quality packages ca... https://blog.yossarian.net/2026/07/07/You-shouldnt-trust-trusted-publishing

How to publish to PyPI using GitHub Actions securely The post gives three practical steps for publishing Python packages to PyPI more securely from GitHub Actions: run zizmor, use Trusted Publishing, and require manual approval through GitHub environments. It focuses on reducing credential risk by removing long-lived PyPI tokens, pinning actions, limiting workflow permissions, disabling persisted checkout credentials, and adding a human ap... https://snarky.ca/how-to-publish-to-pypi-using-github-actions-securely/
