Modernize: Sink Functions
One of the guidelines from Modern C++ is to avoid using raw new and delete. Instead, you should use a smart pointer, a container or other RAII object. Today I’d like to focus on so-called ‘sink...

Beautiful code: final_act from GLS
Sometimes there’s a need to invoke a special action at the end of the scope: it could be a resource releasing code, flag set, code guard, begin/end function calls, etc. Recently, I’ve found a beautiful...

Packing Bools, Performance tests
Imagine you have an array of booleans (or an array of ‘conditions’), and you want to pack it - so you use only one bit per boolean. How to do it? Let’s do some experiments!MotivationThe...

Packing bools, Parallel and More
Let’s continue with the topic of packing boolean arrays into bits. Last time I’ve shown a basic - single threaded version of this ‘super’ advanced algorithm. By using more independent variables, we...

Curious case of branch performance
When doing my last performance tests for bool packing, I got strange results sometimes. It appeared that one constant generated different results than the other. Why was that? Let’s have a quick look...

Please stop with performance optimizations!
As you might notice from reading this blog, I love doing performance optimizations. Let’s take some algorithm or some part of the app, understand it and then improve, so it works 5x… or 100x faster!...

C++17 in details: Templates
For C++17 everyone wanted to have concepts, and as you know, we didn't get them. But does it mean C++17 doesn’t improve templates/template meta-programming? Far from that! In my opinion, we get...
