It's again the part of year when I wish I had a kotatsu in my apartment. Go google it, you will wish it too.

This is my new favorite women's basketball photo, showing Paige Bueckers (6'0") and Zhang Ziyu (7'4"). Please note two things: - Bueckers doing the IRL "😳" face - That both of these women are significantly taller than the average for cis women, yet both are cisgender

Poking about with compile time consteval programming. Finally understanding why @hanicka.net wants everything to be constexpr. Also, trying to bridge the gap from compile time data to static constants at runtime is painful...

If you're dealing with SVG icons you probably know the pain of overwriting colors. There's a new spec in the making that allows controlling CSS variables from "the outside". And it's shipping in Firefox already! drafts.csswg.org...

Code snippet: img { link-parameters: param(--color, green); } and .foo { background-image: url("image.svg", param(--color, green)); }

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.

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

I was wondering. Should a C++ course contain QT and networking? I don't think it's possible to teach C++ during only one semester, so putting additional stuff will make it even more futile.

C++: we have a robust type system, turing complete template, exceptions, overloading, type deduction, concepts to check types. Also C++: here is pointer into a compiler datastructure, it can be anything, you need to check it, otherwise your compilation will fail with a `std::meta::exception`

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

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