Dec 1, 2025Month: 2025-12 — Key feature delivered: Memory management and performance enhancements for the Math Solver in PowerGridModel/power-grid-model. Implemented refactor by replacing most shared_ptrs with references and std::reference_wrapper in MathSolver and MathModelTopology, reducing copying and memory footprint. Commits: 329d59327bfa98b4d6a96ee6807a93740c6dbd40 ('remove most of shared ptrs from math solver files') and 051034d3dc0d455ffb1b12a4a09b756f8229d919 ('adjust to reference wrapper'), both signed-off by Laurynas Jagutis. Impact: improved memory safety, better CPU cache usage, and increased scalability for large mathematical models. No separate bug fixes documented for this month. Skills demonstrated: C++, memory management patterns, references and reference_wrapper usage, refactoring discipline, and rigorous version control practices.

Feb 1, 2025February 2025 monthly summary for PowerGridModel/power-grid-model. The team delivered a streamlined CI/CD baseline, strengthened code quality tooling, and stabilized the development pipeline to accelerate safe releases. Key features delivered include a core refactor of CI workflows with parameter cleanup, enabling consistent build-test-release cycles and reducing configuration drift. Major bugs fixed include reverting SonarCloud changes due to issues and restoring nightly behavior to the prior stable state to prevent pipeline failures. The CI pipeline also accelerated feedback by introducing explicit job dependencies (needs) and improved Sonar integration through token management. Ongoing maintenance activities included comment cleanup and refactors for clarity to improve long-term maintainability. Overall impact includes faster, safer releases, enhanced code quality feedback, and improved security posture through token-based Sonar integration.
