Ing. Jakub Dupak

I like to discover how computers work and what makes software fast (or slow). I also like beautiful code and I enjoy refactoring way more than I should. Finally, I like trying different programming languages and experimenting, how can they help achieve both performance and nice code. All of this combined brought me to my current primary specialization: compilers. I am also interested in computer architectures, operating systems, functional programming, abstract math (languages & automata, universal algebra, graph theory), etc.

So far, I managed to try out C, C++, Rust, Zig, Nim, Python, JavaScript & Svelte, Haskell, Lisp, Kotlin, Java, SystemVerilog, assembly (x86, MIPS, RISC-V) and handwritten RISC-V binary and I am a huge fan of Zig and Rust.

If, for some reason, you would like to reach out to me, write me at random@jakubdupak.com.

  • Memory safety analysis in Rust GCC
  • Abstract: This thesis presents the first attempt to implement a memory safety analysis, known as the borrow checker, within the Rust GCC compiler. It utilizes the Polonius engine, which was designed as the next-generation borrow checker for rustc. The text describes the design of this analysis, the necessary modifications of the compiler, and compares the internal representations between rustc and gccrs. This comparison highlights the challenges in adapting the rustc borrow checker design to gccrs. The thesis concludes with a discussion of the results and known limitations.
