1. A PoC-ish Trick: LLVM IR Generation with Ruby A Lightning

   Talk at RubyConf 2016 Kei Sawada (@remore)
2. None

3. a modern, fast, and open source language for data science

   and technical computing

4. Julia is 4 years old young Good performance, as fast

   as C Dynamic typing Julia has Capability to call C functions directly without wrappers or special APIs a compiler that used LLVM to translate Julia programs into ef cient executable code

5. In short,

6. Write some Julia code then you will get LLVM IR

   without hassle

12. OK Julia is a thing But we are in

13. None

14. What if

15. You can write some Ruby code which can be translated

    into Julia where you can get LLVM IR easily?

16. Ruby -> Julia -> LLVM IR

17. None

18. Julializer Allow you to convert your arbitrary Ruby code into

    Julia code

19. Time to DEMO!
