棘轮：一个只能向前推进的AI交付循环
本文探讨了"棘轮"这一AI交付概念——一个确保每次迭代都比前一次更进一步的开发循环。与传统开发流程可能出现的倒退不同，棘轮机制通过持续集成、自动化测试和增量改进，确保AI系统在每次交付周期中只进不退，从而推动项目稳定向前发展。

A JAX developer found that array lookups on CPU-hosted data took over a second each, because arrays created with the `default_device` context manager are uncommitted to that device. Using `jax.device_put` to explicitly commit the array to the CPU reduced lookup times from ~1.2s to under 0.0002s, fixing a severe bottleneck in LLM training data loading.
