My last blog post dealt with a possible solution to providing a stable memory address. Some of the feedback pointed towards arena/pool allocators to be used instead.

Some APIs allow you to store a pointer to your data element. This is used to access additional information from your types to display them in Model/View Architecture.

In one class I have a string_view which can represent various value types. One of them is a "date-time type", such as a std::time_t or std::chrono::time_point.

Not that I've been away from C++, its just that for the last few years I've been busy with other things to start new projects. And hence mostly did take care of written, productive code. But this has changed now, and I'd like to take my time and learn whats new in C++ land and how to apply this to my new code.

For over 2 years Meeting C++ organizes an online C++ job fair, featuring a form to share your CV/resume with the sponsoring employers. This post is about looking at the aggregate from this form filtered through the regions, which is continents in this case.

I've been wondering if there is another easy way to improve performance of last weeks post on using boyer_moore_horspool search for replacing strings.
Is boyer_moore_horspool faster then std::string::find?

On Wednesday I've read an interesting blog post by Julien Jorge on Effortful Performance Improvements, where it is shown how to improve an replace function which runs replacements on a string. Its part of a series on performance and improving a code base, you should go read all of them!

How does std::any compare to std::variant?

Playing around with std::variant lead to me wondering how std::any would compare to it. Afterall its also a single value store.

I've started sketching out a piece of software that I'm about to write. And part of this is a variant, so I was wondering about variants performance and if the various ways to access its value differ.
