C++ lambda and how the world is different now

So, there was the world of C++ before the lambda. And now there’s the world of C++ since the lambda – and I’ve got to say, if you aren’t using lamdas, then your’e probably still in the C++ stone age. This post is going to be all about lamdas and how rad they are. DoContinue reading “C++ lambda and how the world is different now”

Going Faster With Alignment

So, in the previous post I talked about, fast_remove_if, and going faster than the std::remove_if function. Now there is a further improvement that can be made to go *even* faster, but with no need to modify any functions – instead it involves modifying the alignment of the data in the vector. Here’s the object weContinue reading “Going Faster With Alignment”

fast_remove_if

So you may know about the “erase, remove_if” method of removing elements from a vector. Looks like this: This operation is an order-preserving operation, and “slow” if we don’t care about preserving the order. To remove stuff from an array quick, without preserving the order, you may have heard of something called, swap-remove. That’s whenContinue reading “fast_remove_if”

Spot C++

I feel like when it comes to C++ there is a lot of misunderstanding of what it is, what it can be and how it should be. The average programmer just doesn’t know C++ very well, even though they may use it a lot. C++ is huge and old, has legacy stuff and brand newContinue reading “Spot C++”
