Why not use LLD for linking Rust? You already must have the LLVM for Rust to be buildable, so that do not add any dependency.

I am sorry to break the news, but UK is not in EU, so registering a company in UK is of the same effect as registering it anywhere else outside EU

It's just 6P + 8E + 2IO (ultra efficient) cores or less. Looks it's primary targeting laptops.

For interop between runtimes, they need to add `std::async` IO traits that could be implemented by each runtime.

why not switch to bird that was not affected at all? not just acknowledged and fixed. isn’t it “safe be default” better than “fixed after they pointed the flaw”

I was using the same technique back in the day when I was maintaining my Pentax MXs but using a fluorescent lamp as a source - they blink with the AC power cycle - 50 or 60Hz depending on your country.

The cost of the CPU is small part of a server TCO. Graviton instances could be cheaper because the platform is cheaper, uses less power and needs less cooling - I think we know from Apple Silicon that ARM chips can have these advantages.

Disclaimer: I work for AWS but I don't have any internal knowledge about Graviton pricing and non-public performance data.

I am a Linux user, and I gave on Thunderbird due to terrible Exchange support - now I use Evolution, it has its own problems but my calendar is synced.

P.S. No my choice to use Exchange on the server side.

New comment by karavelov in "Why should you use Tokio vs. threads in Rust?"

karavelov — Sun, 29 Jan 2023 17:29:59 +0000

It matters actually, if your each tasks use 10KiB stack for execution, and you have 1000 tasks, with threads that will consume 12MiB just for the stacks (+2KiB per task due to page alignment). If you use async runtime as Tokio the stack is un-rolled on each suspend point. So if you have 16 worker threads, that means the stacks will consume 192 KiB.
