<p>I wonder how well the caching works. The FAQ says 30 days, so you might be getting a pretty stale result. That combined with Google's "fun fact: 15% of all Google searches have never been searched before", makes me wonder how identifying these queries can be.</p>

<p>The rust language is not well-specified, and if you take rust as the language specified by the compiler, then it has many soundness bugs. So even if you stay within "safe rust", you can segfault.<p>The "memory safety" of rust is oversold since "safety" is not formally proven for the rust language. While anecdotally memory-related bugs seem less likely, rust without unsafe is not absolutely safe.</p>

<p>The author has identified the issue to be memcg reparenting causing a spike in CPU usage. Reparenting mostly solves a problem with zombie memcg, where the memcg lingers because some resource is still charged to it. In the extreme case you can end up with tens if thousands of zombies. The zombie memcg problem is not unique to cgroup v2, but reparenting is fairly recent.<p>The article solves the cpu spike by disabling the io or memory controller, but if one would like to use those controllers, a better way to charge memory would be nice.<p>It is unfortunate that it's clear where the memory should be charged, but the kernel does not provide reliable way to deterministically charge that memory. If anyone has any design ideas, please feel free to chime in!</p>

<p>The support for mTHP exists in upstream Linux, but the swap story is not quite there yet. THP availability also needs work and there are a few competing directions.<p>Supporting multiple page sizes well transparently is non-trivial.<p>For a recent summary on one of the approaches, TAO (THP Allocation Optimization), see this lwn article: <a href="https://lwn.net/Articles/974636/" rel="nofollow">https://lwn.net/Articles/974636/</a></p>

<p>It places a moral judgment on economic growth and production.<p>Which I find deeply confusing as these precisely correlate with QoL compared to life 100 years ago. E.g. the air conditioner was just invented and way more expensive 100 years ago. With the attitude of "as successful as its least privileged soul", I doubt the air conditioner would be nearly as available today.</p>
