What Hacker News says?
So, I dug into this a bit more, and you're right! https://www.fluentcpp.com/2017/06/13/the-real-difference-bet... Maybe it was the era that I learned C++ (which was in the 98 days), but I was taught something closer to this convention, and didn't realize until just now there was such little difference by the book. Just bundling some data together? Use a struct. Doing more? Use a class. I still think this distinction…

HN discussionJulia Evans' blog is one of my favorites! It was a big inspiration for starting my own blog ( https://andythemoron.com ). I also love High Scalability and Dan Luu's blog which have been mentioned in other comments. I "follow" several which are mostly defunct, but in terms of blogs that still feature active updates: Evan Klitze's blog: lots of topics around Linux, C++, etc. https://eklitzke.org/ Sutter's Mill: lots o…

HN discussionThat’s actually what I do whenever I’m lacking humility as a coder. One F12 on std::iterator (which is now deprecated lol [0]) is enough for me to remember that I don’t know anything. [0] https://www.fluentcpp.com/2018/05/08/std-iterator-deprecated...

HN discussionWhen it comes to std::optional, the answer is no. In fact, std::optional<T&> is explicitly forbidden (see here: https://www.fluentcpp.com/2018/10/05/pros-cons-optional-refe... ) It is used in some other places though. For instance, std::string implementations typically employ small-string optimization (SSO) which means that there might be a limit on string::size() since some of the bits inside that value are used fo…

HN discussionIf you're into C++, check out: https://www.fluentcpp.com/ It's a solid resource if you consider yourself a programming athlete. I won't shamelessly plug mine, as it doesn't fit this category yet (programming posts are the least ones I have by quantity), but looking forward to improve that.

HN discussion> In C#, you create a class when it's an object, and a struct when it's a data structure, or am I missing something? Yes and no. Due to the technical limitation that (unlike in C++[0]) structs in C# cannot derive from other structs, DTOs in C# are often implemented (or rather: generated) as classes to allow derivation from a base class that has certain behavioral hooks (say, for misc. custom serializers).

HN discussionFor dynamic languages sure. For strongly typed languages it's better to just use the type system to prevent those kind of things. C++ doesn't have great support here (lots of boilerplate needed) & usually people reach for Boost Units or Boost strong types but it's not that hard ( https://www.fluentcpp.com/2016/12/08/strong-types-for-strong... ). Mozilla is also exploring this specifically for coordinate spaces & wha…

Although the language itself doesn't guarantee that the value is not used again after a move, good static analyzers will provide a warning in that case, so it can still be safely used.

HN discussion> It's super common Curiously recurring, even! [0] Although what you're showing seems to be a variation on the curiously recurring template pattern, as the classes being mixed are listed 'symmetrically' without much regard for which will inherit from which.
