BENEFITS AND DRAWBACKS OF ADOPTING A SECURE PROGRAMMING LANGUAGE: RUST AS A CASE STUDY Kelsey Fulton, Anna Chan, Daniel Votipka, Michelle Mazurek, Michael Hicks 1 Memory safety vulnerabilities Google / https://www.zdnet.com/article/chrome-70- of-all-security-bugs-are-memory-safety-issues/ Case Study: Rust ■ Attempt safety and performance (e.g., no GC) ■ Useful where C/C++ are hardest to like? ■ What benefits (if any) accrue after the adoption of a secure programming language? 3 Case Study: Rust ■ Semi-structured interview with senior developers (I = 16) ■ Survey with Rust community

unit libraries for us? …yes!Are physical unit libraries for us? ● “Physical units don’t cover our use cases” ○ Not just about “physical” quantities/units ● “Don’t handle non-linear units” ○ nholthaus …Digital audio considerations… ● Mostly operating on float ● Don’t want unnecessary conversions ● Use 3rd party APIs (float, unsigned) ● “Modulation rate” is a frequency (Hz)Musical tempo …MIDI example PCM²}What’s next?Are physical unit libraries for us? ● Do all my examples work in Xcode 15? ● Should we use Au in the meantime? ● Contribute to decibel units in mp-units ● Experiment with FFT and complex numbers

Real world Rust Why and how we use Rust in TiKV 黄东旭 PingCAP 关于我 ● 黄东旭 Dongxu_Huang ● Open source hacker / Infrastructure Engineer ● MSRA / Netease / Wandoujia / PingCAP ● CTO of PingCAP ● Codis system programming language ○ Maintain by Mozilla ● Stable: 1.13 ○ Stable enough for production use ● Alternative to C/C++ Why Rust? ● Safe ○ Thread safety guarantee ○ Segfaults free ● Blazingly fn main() { let a = vec![1,2,3]; do_vec(a); println!("{}", a) } 内存安全 error[E0382]: use of moved value: `a` --> src/main.rs:6:20 | 5 | do_vec(a); | - value moved here

Python? ● Writing extensive APIs in Python - low boilerplate ● Familiar for domain experts ● Easy to use ○ Amazing interactive support out of the box (IPython) ○ Jupyter notebooks provide a great research time, others use python to do that Everything compiled with clang++12 -fPIC -O3Some perf numbers: per increment runtime https://news.ycombinator.com/item?id=34663930 Out in the wild case of noticing high boost::python::object ○ boost::python::object is a smart pointer around a PyObject* ○ Only useful to use bpy::object if you’re going to keep it around ○ Why would we want to do this?Arguments to functions
