During my tenure at Google, I had the opportunity to work with several talented interns. One of them, Maria Chizhova, undertook an impressive research project for her master’s thesis titled “Investigation of Virtual Machines for Embedded Languages in Go.” In her study, Maria compared different types of virtual machines tailored for embedded languages, a task crucial for ensuring high performance in various applications.
