Worked on the sched-ext/scx repository, delivering features and fixes focused on kernel scheduling observability and user interface improvements. Developed multi-pane TUI navigation with mouse and keyboard support in Rust, then reverted the feature to maintain stability. Enhanced CI/CD automation using GitHub Actions and automated GitHub Pages configuration to streamline deployment. Addressed reliability in BPF-based CPU statistics collection by guarding against division-by-zero errors in C, improving per-CPU metric accuracy. Experimented with per-CPU ring-buffer streaming for high-fidelity statistics, later reverting to preserve legacy monitoring. Maintained release readiness through dependency management and version control, balancing experimentation with risk-managed delivery.

May 1, 2026May 2026 (sched-ext/scx) focused on observability experimentation and release readiness. An initial per-CPU ring-buffer streaming design for high-fidelity scheduling statistics was introduced to enable continuous CSV capture and loss detection, but was reverted to remove the associated data structures and logic to preserve stability and legacy monitoring paths. The project advanced release readiness with a version bump to 1.1.1 across components. Overall, the month balanced architectural exploration with risk-managed delivery to maintain reliability for customers.

Feb 1, 2026February 2026 — sched-ext/scx monthly review focusing on UI experiments, automation, and maintainability. Highlights include an ambitious multi-pane TUI pane focus and scrolling feature (PaneFocusManager, PaneScrollState) with mouse and keyboard support and per-theme focus indicators, followed by a deliberate revert to preserve stability. In parallel, CI automation was improved by enabling automatic GitHub Pages configuration verification, reducing manual configuration and deployment failures. The work also included targeted refactoring of rendering logic to improve readability and future extensibility (extracting render_scheduler(), bpf_programs_to_display(), and per-view scroll sub-methods).
