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
- Simple, clear, no unnecessary surprises
- Machine learning + scientific computing libraries
- Ease of use + modular: lots of existing functionality to import
- Easy to use interactively through the REPL
What do you like about Rust?
- The cute crab logo :)
- Fussy ;)
- 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!

- 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++

## Cool tools written in Rust
* https://github.com/benfred/py-spy (Bonus: pip installable Rust binary)
## 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!
