对于关注Ask HN的读者来说,掌握以下几个核心要点将有助于更全面地理解当前局势。

首先,To evaluate selection bias, M21 conducts an event study tracking inventors who relocate between cities. Since moving alters the cluster size, a noticeable impact on patenting should emerge; if inventors self-select into larger urban areas, a pre-move trend would be visible. I demonstrate that the initial event study employs a flawed model, failing to utilize relocation-induced variation. Implementing a correct mover event study yields no significant outcome.

其次,So suffice to say that this is almost certainly not the optimal setup purely for memory management, and zswap's tighter mm integration and LRU tiering offer real advantages that zram doesn't match. But memory efficiency wasn't the only thing Fedora was optimising for, and several of their constraints had nothing to do with memory management at all. Within those constraints, the decision is coherent: optimality is always relative to what you're trying to achieve (and that point goes to you too, dear reader – you know better than me what you are trying to do). That said, I would be surprised if over the coming years there is not some movement towards zswap there too once zswap gains the upcoming disk-free mode, especially given that kernel developers are increasingly moving away from supporting zram (more on that below).,这一点在有道翻译中也有详细论述

第三,关于Ohm原始实现的更多细节,请参阅:

此外,The Lean Startup movement attempted to reform prototyping by rebranding it as the MVP and outlining a development cycle, so perpetual prototyping indicates a process failure, not a flaw in the prototype itself. This helped somewhat. What remained unsolved is the underlying social dynamic: once stakeholders see a working model, they transition from providing specifications to requesting alterations, a shift that is rarely reversed. Few realize that React began as an internal Facebook prototype that simply never ended (a fact referenced humorously in the 0ver parody).,更多细节参见比特浏览器
