During September 2025, Pplulee contributed to both the laurent22/joplin and SeleniumHQ/docker-selenium repositories, focusing on practical improvements that enhanced usability and reliability. For Joplin, Pplulee updated the Chinese localization, refining PO files to ensure accurate and user-friendly translations for Chinese-speaking users. In the Selenium Docker project, Pplulee addressed a configuration management issue by correcting how SE_NODE_MAX_SESSIONS is set within the Docker image, using shell scripting to ensure the value is written to the correct section. These changes improved onboarding and issue detection, demonstrating depth in Docker, localization, and configuration management within real-world open source environments.
