Much appreciated!

But let me ask you.... In high performance application, like game development (like Unity) - it is good to know Spans/Memory of ? Like when I need to calculate "millions" of data (position, rotation, etc...) with maximum performance - I must use these right ? (must.... Like.... I should to!)

I haven’t written any games since I was using a C-64😂

I can imagine them being out to use in a game.

That's so nice to hear! I've always loved the "internals" stuff, so it feels great to share with others.

Thank you for the supportive comments! I'm really enjoying it.

Thank you!

Thank you! I’m curious what’s you use case for Vector of T?

@@JeffZuerlein used in computation and machine learning as well gaming

I appreciate hearing that, and I will.

I understand that feeling. I don’t think spans and memory are for every project. I see them as a special tool for a special situation. When perf matters, it’s nice to know you have the option.

Making fun of *any* programming language is for junior developers. Seniors use each to their strengths. Span allows for low-level optimizations in high-performance scenarios, without sacrificing all the benefits of C#, like type- and memory-safety. Span comes with a lot of safe-guards, while C++ is *always* low-level, giving you more "freedom" but also more risk.

@@mar_sze Question: Why should I not make fun of programming languages? They all have ridiculous features/notation/etc. Being allowed to use almost any date-type in an if-statement in C is hilarious, not to mention while loops intertwined with switch statements. Notation in C++ to remain backward compatible is sometimes ugly as hell and oftentimes super confusing for novices. Object oriented programming in Fortran90, what a joke it is. And so is C# filled with features that can be frowned upon. You see, as a senior developer I make fun of these things to remind people that programming languages are like a buffet where you should choose wisely what to eat and what not.

There is plenty of code I like to make fun of…It has one author…Me. Over the years I’ve written plenty of programs that solved a problem, but suffered from many faults. It might look ill conceived, but that’s ok, it got the job done, and I got better because of it.

Trade offs…It’s always a trade off. Everytime I interview someone for a position, I tell them I like working in a collegial team. I want to hear their ideas, and I want them to tell me when they think I’m wrong. At the end of the discussion, I expect we’ll both have learned something. There is a lot of value in perspective, and seeing the trade offs.

​@@JeffZuerlein Yes, trade offs are key, but oftentimes programmers have almost religious feelings about their 'holy' language. I used to have similar feelings decades ago, so I do understand, but I simply don't share this religious point of view anymore. And, for the record, the fact that I am a native C and C++ speaker does not imply anything. I am a native Dutch speaker as well, but I don't regard Dutch as the best language in the world. Not even close. But I can order a pizza in Dutch, and I can say Groningen and Scheveningen with the correct pronunciation. That's skill you see, very hard to master, but it is not an important skill. Junior programmers can hotly debate things in terms of 'better' and 'worse', whereas they should ask a bit more the 'what is it that actually matters' question. What are the true objectives of the project? On-time delivery? Performance? Maintainability? Flexibility? Being able to run on an FPGA? You can't have it all you know. Trade off it is, and I would like to know where the focus lies before I accept a position in my virtual job interview with you. This would be a fun discussion for sure, and we both might indeed learn something. Too bad I already have the best job in the world.
