Explore a 32-minute conference talk from Strange Loop 2013 introducing Dao, a lightweight and optionally typed programming language. Discover its expressive features and simplified approach to concurrent programming. Learn about Dao's virtual machine with easy embedding and extending capabilities, its LLVM-based JIT compiler optimized for numeric computation, and a Clang-based tool for automatic C/C++ library binding generation. Gain insights from creator Limin Fu, a multidisciplinary researcher with expertise in mathematics, physics, computer science, and bioinformatics. Delve into topics such as Dao's development motivation, syntax style, performance expectations, optional typing, code section black method, decorators, mixins, aspects, and concurrent programming techniques including asynchronous function calls and multithreading. Conclude with a glimpse into Dao's future development plans.
