Benchmarking Kaby Lake and Haswell memory latency using lists — Modern CPUs are complex beasts with billions of transistors. This complexity in hardware brings indeterminacy even in simple software algorithms. Let’s benchmark a simple list traversal. An average node access latency corresponds to CPU cache latencies. Or does it? Let’s put it to the test! “Do I Know This Already?” Quiz

The best way to return multiple values from a C++17 function — “Do I Know This Already?” Quiz What is the best way to return multiple values from a C++17 function? Using output parameters: auto output_1(int &i1) { i1 = 11; return 12; } Using a local structure: auto struct_2() { struct _ { int i1, i2; }; return _{21, 22}; } Using an std::pair: auto pair_2() { return…

Can’t find a stock image? Let’s take it! — Good images make a blog post, article or presentation perform better. Original images make our work distinguish and unique.
