Anukari: macOS Realtime Physics Audio Synthesizer Performance Issues

2025-05-06

Anukari, a GPU-based real-time 3D physics audio synthesizer, performs well on most macOS systems. However, on some high-end Apple Silicon devices, its performance degrades due to macOS's power-saving GPU strategies. The author attempted to solve the problem with a "waste makes haste" strategy (running an extra workload on the GPU to increase its frequency), but this fails on high-end devices due to independent frequency regulation of multiple GPU chips. The author calls on the Apple Metal team to help solve this problem and proposes possible solutions, such as extending the concept of Audio Workgroup to the GPU or adding a real-time sensitive option to the Metal API.

Coding ≠ Programming: A Turing Award Winner's Perspective on Abstraction

2025-05-05

Leslie Lamport, an 84-year-old Turing Award winner, delivered a keynote speech emphasizing the crucial difference between coding and programming. He argued that abstract thinking before coding is paramount, leading to fewer errors and more efficient code. His own TLA+ specification language, used in the Rosetta spacecraft's development, serves as a prime example, demonstrating significant code reduction and architectural improvements. Lamport criticizes programmers' tendency to focus on languages instead of abstract design, advocating for designing the program's abstract model first, then coding. This approach minimizes debugging and revision, resulting in cleaner, more maintainable code.
