让LLVM再次更快起来
Make LLVM fast again
https://nikic.github.io/2020/05/10/Make-LLVM-fast-again.html
因为有报告显示LLVM V10编译Rust语言性能居然降低了10%。虽然LLVM的主要目的是编译Clang的C/C++,但是还有有必要让LLVM跑起来更快才行。

用Rust语言写Wayland排版器 - 下一代Linux的X11图形库和UI界面的组件
Writing A Wayland Compositor In Rust
https://wiki.alopex.li/WritingAWaylandCompositorInRust
Wayland是Linux的下一代API,用于取代X11图形库和UI。Wayland的排版器叫Way Cooler. Wayland is Linux’s next-gen API to replace X11 for graphics and user interaction, so this was pretty cool, two next-gen technologies playing nice together.
几年前曾经有过Way Cooler放弃Rust语言而改回用C语言做编程语言的事情:https://way-cooler.org/blog/2019/04/29/rewriting-way-cooler-in-c.html
Rust语言和C++语言安全性和性能操作对比

C++ Is Faster and Safer Than Rust: Benchmarked by Yandex
Yandex的Benchmarked分析结果显示:C++比Rust语言更快更安全。大家可以直接仔细看测评报告原文。
这篇文章有意思。更像是站在 C++ 这边的一个高级程序员对 Rust 的吐槽(似贬实褒,找出 Rust 目前可能不足的地方)。内容目录如下:
- Myth 1. Rust's arithmetic is no safer than C++'s
- Myth 2. The only strong point of Rust is object lifetime analysis
- Myth 3. Rust's function calls touch memory without good reason
- Myth 4. Rust is slower than C++
- Myth 5. C → C++ — noop, C → Rust — PAIN!!!!!!!
- Myth 6. unsafe turns off all Rust checks
- Myth 7. Rust won't help you with C libraries
- Myth 8. Rust's safety isn't proved
- Conclusion
