Icebreaker

Are you writing Python and/or Rust (add an "o" at the end of the line)?

• Python: ooooooooo
• Rust: ooo

If yes, what do you like about Python?

• Clear, organized model and principles
• Unfussy
• Simple, clear, no unnecessary surprises
• Machine learning + scientific computing libraries
• Ease of use + modular: lots of existing functionality to import
• Extensibility
• Easy to use interactively through the REPL
• …

What do you like about Rust?

• The cute crab logo :)
• Fussy ;)
• Safety
• Tooling (Cargo)
• Parallel libraries like Rayon
• Leaves me less shellshocked than C++
• I heard it's fast and safer than C++
• The speed. And the noise. And the noise of the speeeeeed!

Bio: Radovan Bast

• Computational chemist turned research software engineer
• University of Tromso, Nordic e-Infrastructure Collaboration, and Serit (Norway)
• Working on https://coderefinery.org/
• Otherwise working on:
  • few small libraries for computational chemistry
  • text analysis tools
  • computational geometry
  • optimizing codes
  • trying to improve usability and documentation on Norwegian high-performance computing resources
• Spent few years writing Fortran, C, and C++
• These days using Python (quick prototyping) and Rust (for its robustness, correctness), also JavaScript (because I don't like hosting own web servers)

Ask your questions here

• This is how I ask a question?

  • Yes it is
    • And this is another comment
    • Everyone can ask and answer questions :)

• How about CUDA/HIP/…? Is it also too early for this?

  • When in doubt: go through C interface.

• So what happened to s1 in that example? It's not garbage collected as there's no garbage collector?

  • we can imagine that it got dropped (deallocated). more precisely, the ownership got moved so s1 is not pointing to that data anymore.

• What about publishing source packages to PyPI?

  • Okay thanks

• What does the & mean in Rust?

  • Reference to

• What does cargo check check?

  • checks that all types match

• PyO3 seems to have ways to reflect/wrap Python types into Rust but is there a way to have reflected/wrapped Rust types in Python like PyBind11/Boost::Python?

  • Yes I think you showed it. Thanks.

Thanks for the talk!
thanks!
