    Moderna and Pfizer tested variant-specific (B1.351) boosters and found they weren't significantly more-effective than a third dose of the original vaccine. https://www.nature.com/a…

    Google implemented fibers. Hopefully they'll get upstreamed. https://www.youtube.com/watch?v=KXuZi9aeGTw

    For large allocations, realloc can remap virtual memory instead of doing a naive copy: http://blog.httrack.com/blog/2014/04/05/a-story-of-realloc-a...

    A networking library based on Asio has been proposed for C++17. In the meantime, use Asio. http://think-async.com/

    It's good to have competition in this area. Influx is giving me whiplash (it's on its third database engine in six months!) The circular buffer approach is fine, but it does have t…

    Yeah, but... Need replication? Gotta write your own sharding logic or set up pg_shard. Need aggregations? Gotta write your own logic. Will you do them on the fly? Use triggers? On …

    Yeah, I'm not brave enough for embedded. I'm still pretty excited about what's happening in this space though. Thanks for your thoughts.

    I apologize if I gave the impression I was claiming otherwise. It's just context for the discussion.

    The author also points out that some of the benchmarks poorly represent real workloads: "Bottom up (since the worst offenders are now first), binary-trees is silly since it measure…

    Ah, so Rust does represent thread semantics through types? It's curious that the authors don't mention that in their proposal.

    Basic question — when you're writing a kernel in Rust with its own threading implementation, how does the rust compiler even know what threads are? It has to identify thread bounda…

    Any thoughts on C++ coroutines? Microsoft has a draft implemented in their compiler, and there's a second competing proposal. https://msdn.microsoft.com/en-us/magazine/mt573711.asp…

    I think every OS does this to some extent. Windows uses DPCs, Linux uses tasklets.

    That might make you the biggest company using Rust? Very cool, I hope you write it up.

    Oh OK, that's cool. I don't think many languages could enforce that.

    I was thinking async-await, which I thought hasn't been standardized yet. Do generators provide the same functionality? Either way, I hope Rust skips the callbacks.

    Scope-bound resource management (SBRM) is clearer than RAII, I think.

    And... how would that be possible at compile time?
