注册表被认为有害
本文深入探讨了软件生态系统中“注册表”(Registries)模式(如包管理器注册表、服务发现注册表等)的潜在危害。文章指出,虽然注册表在集中管理和分发资源方面提供了便利,但它们引入了单点故障、信任依赖、中心化控制等风险,并可能抑制去中心化创新。作者呼吁业界重新审视注册表架构,探索更健壮、更去中心化的替代方案。

Raymond Chen continues his series on cross-process reader/writer locks by addressing fairness, ensuring exclusive (write) acquisitions get a fair chance against repeated shared (read) acquisitions to prevent writer starvation.
The article discusses fractal page mapping, a technique for mapping page tables into memory using the page tables themselves. This approach allows the operating system to access its own page table structures through the virtual memory system it manages.
The article explains that when a C++ compiler reports an error about code you didn't write, you should investigate who actually wrote that code. This helps in understanding misleading error messages like "illegal use of ->" when no arrow operator appears in your source.
The article examines what happens when a C function receives fewer register parameters than expected across different CPU architectures, concluding the outcome is always problematic but especially severe on Itanium.
This post continues a series on building a cross-process reader/writer lock, focusing on handling the scenario where a process holding the lock is terminated, requiring recovery mechanisms for the abandoned lock state.
