I'm maybe too deep in the rabbit hole. libstdc++'s file_clock::time_point has nanosecond precision, and ends on original expected return date of Voyager from the delta quadrant. Anything past that will travel into past.

$screenshot of libstdc++'s source code from chrono.h header containing comment and one constant: // This clock's (unspecified) epoch is 2174-01-01 00:00:00 UTC. // A signed 64-bit duration with nanosecond resolution gives roughly // +/- 292 years, which covers the 1901-2446 date range for ext4. static constexpr chrono::seconds _S_epoch_diff{6437664000};$

This is how you can spend a lot of compute without touching any slop and also show a cute sneak-peak of C++29:

$Snippet containing following code: consteval { constexpr std::string checksum = cthash::sha3_256( std::embed( std::source_location::current().file_name() ) ).final() | base64url; static_assert(checksum == "r7keMbld38TMWxee6G5O2dXVaBsP7rFbIflWTAN0nQE"); }$

Have fun... and if you have time go on the maroon lake.

A dark lake in a valley with a huge pyramid shape mountain covered in snow with some rocks visible. The valley on right side is full of leafless trees as it's really early spring. The slope on left side is all snow. Above the mountain summit there is a huge cloud surrounded with dark blue sky, sun is just on right outside of the frame.

Oh I love Toni Onley'a work. I have one of his paintings...

A picture of painting named "ravencreek pitt lake BC", within golden/bronze-ish frame with white mat around the painting which is a paper which looks like being teared out of a roll of paper at bottom. The watercolor painting itself is in cold colors, white to teal blue. There are mountains on right and farther in back with rocky peaks crowned with snow. With some dark low fog in distance on surface almost dark-grayish-green lake with a greenish-orange beach with three almost human like dead trees standing next to each other. With clear blue water and some rock in front.

My potatos in bowl after I forget about it for few hundred years.

If you experience performance issues while scrolling in macOS Tahoe. You can fix it by setting following default for the app itself: defaults write com.macromates.textmate NSAutoFillHeuristicControllerEnabled -bool NO

Charlotte is not really happy, but Zarja is too attached on her today.

Two italian greyhounds, grey on left named Charlotte and ginger on right named Zaria, both laying down under blanket with only their heads visible. Zaria has head put on Charlotte's side. Both are looking into camera. Charlotte doesn't seem to be excited.

If yo want to see the HDR image in its glory, use chromium based browser on a system which supports HDR images (best result is on MacBook Pro with XDR display) hanicka.net/sigma/bryce-...

TIL about gain maps which allows JPEGs to contain HDR stills. So this is a test if the gain map is lost here or not.

`__builtin_unreachable()` and `std::unreachable()` are terrible for code coverage, because these branches are not emitted and testing them is nearly impossible. So a small WIP in marking these in code coverage analysis properly:
