I've started using digit separators when checking the value of __cplusplus and feature test macros, and i am liking it. 2019'02 is less work for my old brain.

Really great talk covering GPU perf stuff including optimizing for memory bandwidth / cache and occupancy.
Relevant to any GPU perf considerations, not specific to CUDA.

UPDATE: stdexec gets native support for ASIO!
HUGE community contribution from github user @RobertLeahy, an expert in both ASIO and std::execution.
With the new `use_sender` completion token, ASIO's async APIs return senders. Now you can program generically with async network operations!

is there a good tool, possibly a vscode extension, for splitting git commits?
i have a workflow in mind: define some empty "commits" and then graphically drag chunks into each one.

At first I thought this was a shot in the spaces-vs-tabs war and was like WHOA vertical tab characters MAJOR escalation.
I'm a vertical tabs convert, super space efficient with them collapsed and that CTRL+Z key command (to expand/collapse) is getting committed to muscle memory. Thanks @firefox.com 🦊

i am constantly looking up:
* the C++ feature test macros
* the printf format specifiers
* the Doxygen special commands
i've been doing this for 30+ years. i should just make posters and hang them above my desk already.

In the book Swan Song, the Devil strolls into a movie theater chuckling to himself while WWIII is bringing a rapid end to human civilization.
He's laughing because he didn't have to do anything.
The humans are blowing themselves up.
I think about that a lot.

In the world of Functional Programming, is there a term for a type transformation like:
F [a,b,c] -> [F a, F b, F c]
Is this some sort of monadic something-or-other?
F [a,b,c] -> [F a, F b, F c]
