This lecture brings back lots of old memories when I was first introduced to C++ in my sophomore year as a computer science student at CSUN -- around the same time of this recording. Sadly, I had very little understanding of object-oriented programming at the time, but I was always fascinated by its paradigm. C++ (Visual C++) was the first language that I learned about OOP, right before I was introduced to Java in around 1995-1996.

It would be a dream of mine to meet that man. Just a fantastic human being :) I have NEVER done anything worthy by writing software. In the early 1990's I was introduced to the "home computer", and in the late 1990's I took some programming classes at a (very expensive, overrated university), and decided that I want to be a "programmer". One of the books we used in the C++ class was the Deitel & Deitel one. That didn't happen. I ended up transferring in year 3 of my IT degree to a community college (yeah, stupid) and got an A.S. IT there, and never found a job with it upon graduation. At community college I took courses in things like Java, and did poorly. In the early 2000's I bought numerous programming books from the likes of Barnes & Noble and then from Amazon, thinking that "if I just get THAT book, then I'll be able to write software". One book I bought was one of Barne's older C++ books. In the late 2010's I was homeschooling my son along with my wife, and I bought MORE programming books. While I did teach how to write simple computer programs, my own frustrations at not having met my own dream of being a programmer manifested themselves in my son ultimately hating doing any programming. Upon my divorce from her, I threw away many of the books. Surely by now I'd never have to worry about those programming books again! In the past two years I've gotten MORE books, and threw others away, and at one point I was liking PHP & MySQL. I even made a heart beat/pressure tracker for my husband. In the past few months I've started thinking about programming again, and one of the books I just received in the mail today was Barne's book Principals & Practices Using C++, and I have to say that I am really enjoying this C++ book. Despite my frustrations with programming over the years, SOMETHING about it keeps drawing me back. Fingers crossed this time :)

[@MilesBellas]

via Wikipedia "In 1979, Bjarne Stroustrup, a Danish computer scientist, began work on "C with Classes", the predecessor to C++. In 1982, Stroustrup started to develop a successor to C with Classes, which he named "C++" (++ being the increment operator in C) after going through several other names. New features were added, including virtual functions, function name and operator overloading, references, constants, type-safe free-store memory allocation (new/delete), improved type checking, and BCPL style single-line comments with two forward slashes (//). Furthermore, Stroustrup developed a new, standalone compiler for C++, Cfront. In 1985, the first edition of The C++ Programming Language was released, which became the definitive reference for the language, as there was not yet an official standard. The first commercial implementation of C++ was released in October of the same year. In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for the future standard. Later feature additions included templates, exceptions, namespaces, new casts, and a Boolean type. "

I find this funny... I can't say I'm keen on C++, the language, itself. I've done plenty using it... and I find no joy there. BUT... I love to listen to and read Bjarne Stroustrup talking about how he designed it... "The Design and Evolution..." is one of my all time favourite books. And this talk is very good too! Back when I was at college, we all wanted to use BCPL, because it was a "real grown-up language"... (sigh)... nostalgia! I LOVE his simplistic view of types and classes that he uses here.... free of the "religious mania" that OOP has now, it still sounds like a reasonable idea. "No gratuitous features".... I wish the ECMA-script committee had held on to that one!!!

[@Hans_Magnusson]

My view on languages is: The language allows you to express your ideas, in this context, in a clear an concise way. The better the language is in supporting the human way of expressing ideas, and at the same time, the better this could be translated to the way a machine understood it…. It will enable you to craft exceptional results! C++ is a great language for the purpose it was designed for. It has a vast set of features which takes some time to master. The real challenge imho is how we are taught how to program. Some people never recover 😎
