paulmck.livejournal.com is a personal blog at paulmck.livejournal.com about programming and systems. Since 2011, 32 different Hacker News readers have linked it 43 times, most often “So You Want to Rust the Linux Kernel?”. No feed was found, so read it on the site itself.
Too few sampled comments (9) to say how often HN recommends it.?
Why HN links it
HN readers link Paul McKenney's journal for its long series on RCU, memory models and parallel programming, including Rust in the Linux kernel. Commenters point to the series index and suggest starting points.
Summarised by Claude from a sample of 9 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
> This means that using it for the core parts may be feasible sooner rather than later, no? More like much later. There are several performance-critical patterns used in the Linux kernel that are difficult to express in unsafe Rust and impossible to express in safe Rust. See https://paulmck.livejournal.com/62436.html and especially https://paulmck.livejournal.com/64209.html I think promoting the use of Rust for driv…

HN discussionHere's a pretty good blog post that discusses how the memory models could interact: https://paulmck.livejournal.com/65341.html My understanding is that it might not be entirely settled yet, and is still being discussed. That could explain why there isn't much solid documentation written yet

HN discussion> Given that DEC Alpha famously had difficulty with RCU, it is only reasonable to ask how Rust will do with it. > Including some wild speculation about how Rust's ownership model might be generalized I recommend starting with the latests post in the series and the conclusions( https://paulmck.livejournal.com/64209.html and https://paulmck.livejournal.com/65056.html ). From the snippets at the beginning, it looks lik…

HN discussionI shared this perspective, but luckily my job is awesome and (in a routine 1:1!) Paul told me why it's less straightforward than I thought: https://paulmck.livejournal.com/62436.html my takeaway was essentially that you get sweet perf wins from semantics that are hard to replicate with a type system that's also making really strong guarantees without making the code SUPER gross.
