PROFILE
Stephen Schiffli
During a three-month period, Sam Schiffli enhanced the apache/guacamole-server project by delivering three user-focused features. He first improved terminal navigation by implementing a clickable scrollbar track with snap-to-middle behavior, using C and event handling to streamline user interaction. Next, he refactored the terminal’s text selection logic, introducing a new structure for precise selection and expanding unit test coverage to ensure reliability across edge cases. Finally, Sam strengthened process management by adopting prctl-based orphan process handling and group-wide termination with SIGTERM, reducing zombie processes and improving system stability. His work demonstrated depth in C programming, GUI development, and system programming.
