Do you get anxiety not knowing if your unordered_map hash function does a proper job? Fret no more! https://t.co/jKgxxZUfEQ #cpp #hash #unordered_map

@chriskwallis Do you have any idea why see a 3% performance difference for a 0.3% difference in quad counts?

[Philip Trettner @PhilipTrettner]

@dima_savin @LesleyLai6 I didn't test it myself but I hear that it didn't use to work in range-v3 but works now (at least zip but not zip_with). Also, it might not work with zip from the C++20 ranges.

Using std::sort to sort multiple ranges

constexpr does not mean compile time evaluation. Here is a small utility to force compile time evaluation even in C++17: https://t.co/RaaSxoaGnS #cpp

[Philip Trettner @PhilipTrettner]

Well we don't have "constexpr for"... but we can certainly try to make our own! https://t.co/g9Y96PhFL8 #cpp

Multi-Level Break in C++ using Immediately Invoked Function Expressions! (please don't hate me) https://t.co/kWKHVuBJvl #cpp

Something is fishy with my karma today. I found another compiler bug: https://t.co/lydO1Mldth
I just don't know for which compiler yet ... #cpp #spooky

[Philip Trettner @PhilipTrettner]

Not quite Halloween yet but still got spooked by msvc today! Long story short, this code exhibits quite remarkable spooky action at a distance: https://t.co/ynCx7aj6pb (fingers crossed that my report at https://t.co/AlMZ2cn9ZJ gets fixed)

BVHs and BSPs are similar but not quite the same. Both are (usually) binary trees but BVH nodes can spatially overlap while BSP nodes are spatially disjoint. BVHs handle non-point objects better, BSPs are slightly more compact in memory.

[Philip Trettner @PhilipTrettner]

PSA: including <typeindex> makes std::hash available (e.g. for specialization for custom classes). WAAAY cheaper than <functional> #cpp

After the success of std::string_view and std::span, may I present to you: range_ref<T> https://t.co/OL5wOT7evP

Today's post got a bit longer than usual but it's packed with many intermediate C++ tidbits! #cpp https://t.co/CzAmLaCMC1

[Philip Trettner @PhilipTrettner]

Overloading functions by argument type is cool'n'all, but have you ever tried by return type? #cpp https://t.co/QC8fYgm3wW
