The article discusses the comparison between Rust and C programming languages in terms of performance. It explores various aspects such as inline assembly, struct size differences, social factors influencing code safety, and compile-time vs runtime checks.
- Rust has inline assembly built into the language.
- C uses compiler extensions for inline assembly.
- Structs in Rust can be reordered for optimization, unlike C structs.
- Safety checks in Rust may lead to different code compared to C.
- Some argue that compile-time safety checks do not necessarily make one language faster than another.
Quality:
The article presents a balanced view on the comparison between Rust and C, discussing various aspects without promoting one language over the other.

The discussion revolves around the comparison between Rust and C/C++ in terms of performance, with participants discussing various factors such as compiler optimizations, memory semantics, aliasing rules, and language features. The community dynamics show moderate agreement on nuanced perspectives while acknowledging the complexity of making generalized conclusions about language speed.
- The article does not mention additional optimisation opportunities in Rust code due to stricter aliasing rules.
- C programs can be faster when compiled with C++ compilers because of stricter aliasing and type rules.
Counterarguments:
- Benchmarks for Rust code with optimizations turned off do not compare Rust to C directly.
- The semantics of 'noalias' markers may not fully utilize Rust's aliasing model.

Exploration of GitHub's dual ID system for object identification
This article could help developers optimize their use of GitHub's API and improve the efficiency of their code, potentially leading to better integration with GitHub services.
- GitHub uses two separate ID systems: node IDs and database IDs.
- Node IDs are base64 encoded strings, while database IDs are integers.
- The author discovered a method to extract the database ID from the node ID using bitwise operations.
- Legacy repositories use an older format for their IDs, whereas newer ones follow a new format based on MessagePack serialization.
Discussion (64):
17 min
The discussion revolves around issues and opinions related to GitHub's migration to new ID formats, lack of proper documentation, and the implications for developers relying on undocumented behaviors or internal implementation details. The conversation touches on Hyrum's Law, developer responsibility, and system stability.
- GitHub's migration to new ID format was not properly documented
- API documentation should clearly state that IDs are opaque
Counterarguments:
- It is the developer's responsibility to not rely on undocumented behaviors or implementation details
- Changing ID formats could break existing systems, so documentation must be clear about potential risks
