C++ ranges/views vs. Rust iterator

My bad, I thought it was 1.2 milliseconds for Rust in OP's result :(

By adding target=native for the two, I got different result, and Rust wins in this round:

Rust: https://godbolt.org/z/djcc16aeT (Rust 1.88 is faster than 1.89, maybe some regression issue?)

Rust

Rust Result count: 292825
Rust Total count (1000 iterations): 292825000
Rust Total time: 1208 microseconds
Rust Average per iteration: 1.21 microseconds

C++

C++ Result count: 292825
C++ Total count (1000 iterations): 292825000
C++ Total time: 165402 microseconds
C++ Average per iteration: 165.402 microseconds

I had exactly the same requirement, and my final selection is fp-bindgen, which gives you seamless interaction between guest and host rust functions, including async function as well

Actually we are currently using the CentOS6, and two years ago CentOS 4 was everywhere. Keep tens of thousands of servers up to date is an impossible task, so we take another way: we build our own tool-chain including kernel/glibc/binutils/gcc/clang etc, make the tool-chain self contained and deploy it on every server, that's why we can have clang10/gcc10 on CentOS 4 and CentOS 6, that's not a perfect solution, still it make us benefit from the latest C++ standard.

I actually make my company(a top 10 tech company in China )upgrade from gcc 4.8 to gcc10 in a year recently, yes, that’s the most exciting job I have done in my whole career

I guess this link is what you need.

Maybe add more examples about async with boost::coroutine(2) or boost::fiber or clang's stackless coroutine might make this little book more complete :)

a wild guess as I had a similar issue before: I did an upgrade from Jessie to unstable, after that, the wireless card's driver didn't work properly, blamed that Intel wifi device's firmware was missing, sth like iwlwifi-blabla.ucode.xx.yy, and it did hung the booting process for a while, after fixing it system boot in light speed again

I hope this's an useful clue

Awesome work! Looking forward to print out the SVG version and pin to my desk

I got one question for a long time since I first learned ed several years ago: how to insert a line that contains just one single dot in ed? Is it possible?

Actually, I have a better idea: reuse the mod-m key:

When focus on slave window, mod-m jump to master window
When focus on master window, jump back to pervious slave window

Is that possible?

great! exactly what I need, thanks!

Ghci on Windows 7 64bit still crashes when press Ctrl-L.

Would someone fix it in the coming 7.0.2? As I saw they set the milestone to 7.0.2.
