Callum Thom contributed to both the ruffle-rs/ruffle and NationalSecurityAgency/ghidra repositories, focusing on runtime robustness and parsing accuracy. In ruffle, he refactored AVM1 base clip handling to use string-based references, improving closure scope management and error messaging using Rust and ActionScript. For ghidra, he enhanced MIPS16 disassembly by adding MIPS16e2 instruction support and fixing decoding bugs, leveraging assembly language and bitwise operations. He also improved the CParser component in Java, enabling accurate parsing of Microsoft-specific integer literals and suffixes. Callum’s work demonstrated depth in low-level programming, parser development, and reverse engineering, resulting in more maintainable codebases.

Mar 1, 2026

March 2026 monthly summary for NationalSecurityAgency/ghidra: Focused feature delivery on the CParser component to improve Windows/Microsoft dialect support and parsing accuracy. Delivered Advanced Integer Literal Parsing for the Microsoft Dialect, including Microsoft-specific suffixes (i64 and I64) and broader suffix handling for hexadecimal and octal literals. The work included two commits and a review iteration to refine edge-case handling. No major bugs fixed this month; the primary business impact is improved compatibility and reliability for Windows-centric C/C++ code analysis and decompilation, reducing parsing errors and enhancing downstream analysis workflows. Technologies and skills demonstrated include CParser internals, parsing edge-case handling, Microsoft dialect compatibility, and collaborative Git review processes.

July 2025 — ruffle-rs/ruffle: Stabilized AVM1 execution by delivering Base Clip Handling Improvements. Implemented clearer error messaging for missing base clip and simplified the logic to determine the correct base clip, ensuring the proper display object is used as the base clip, especially in closure scenarios. These changes reduce panics, improve rendering accuracy, and set the stage for easier future maintenance.
