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/articles/s41591-021-01527-y This

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

>Many of Rust's safety guarantees come from compile-time checks that then do not have any runtime penalty. But not bounds checks, which are unfortunately what you need with respect to buffer overflows.

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/

>A rotating disk is roughly able to saturate a 1Gb ethernet link. Locality is key there. Read randomly and you won't saturate a 100Mb link.

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 the drawback of being unable to represent variable-

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 demand? Need to remove old data? Gotta set up a cron job. Bu

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 measures allocation speed for a case that simply doesn't

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

Unmanaged native code definitely has an edge, even in I/O-heavy applications like databases. http://www.scylladb.com/technology/cassandra-vs-scylla-bench... Not to mention low-memory environments like mobile.

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 boundaries for send/sync, right?

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.aspx http://www.open

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.

by acconsta 11y ago
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?

50% C++, 25% Java http://qr.ae/RP7wXh At Google's scale, the performance difference between Java and C++ can means millions of dollars in electricity alone.

>Even Google mostly uses Java I'm not so sure about that. The core services (e.g. Search, Maps, Earth, Big table, Map reduce) seem to be C++. Ads is possibly an exception.

A Node-style event loop leads to callback hell. It would be awesome to have something like Boost Asio.
