Lex, thank you greatly for interviewing Bjarne Stroustrup! He has been a personal hero of mine for the last twenty years or more. He is not only a supreme engineer but also an adroit consensus builder. That is a rare combination and his consensus building seems to have played a critical role in forging the success of C++. I highly recommend his "The Design and Evolution of C++" to anyone interested in computing history, language design, or even politics. To me, Stroustrup's approach seems to be 1) understand the "customer's" problem and needs 2) assess the shortcomings of existing tools and prior art 3) design simple, pragmatic, correct solutions to fill the gaps and 3) deliver and communicate those solutions with humility. That is an admirable process I aspire to emulate.

[@TheSulross]

In the early 90s I met Bjarne at a Usenix conference. Presented a problem per C++ and a proposal to address it, that he took an interest in and we corresponded via email for a while about it. Alas, at the time RTTI ended up being the lion share of C++ mindset for new improvements. And the problem I was looking at ended up being addressed by Microsoft with their COM implementation - which made it sort of feasible to have more or less practical runtime loadable modules extendability. But what was cool was that Bjarne is a great guy that is not aloof, but approachable. Lot of flame wars over the decades saying this or that, but in my book, Bjarne is a class act. And he's a giant in the world of computer science and programming languages.

This guy talked about the “turning left of different vehicles” being the spark of inheritance and polymorphism, and now I understand it 😂 it’s safe to say, there’s only one person who can truly teach c++, and that’s the inventor of it lmao. It’s makes sense to define a virtual turn left method and then whatever vehicle off the base class can use it for its form of vehicle at run time. Truly amazing story and explanation. C++ is great.

[@philipogunbona8602]

Lex, thank you very much for bringing the legendary Bjarne to your channel. 🙏. The question about comparison between machine learning and C++ is unclear. One can implement machine learning in a variety of languages including C++. Machine learning is a way of building the model that describes a system using extensive data collected from the system while operating. The form the model takes may be different from the usual analytical closed form that one may be used to, but once the model is learned, programming the system is no different from what we have always done. A closed form analytical model is prone to error as much as a model derived from learning from data. The main difference is that we feel comfortable with closed form analytical model because we can name the variables and their interactions in the model. But a model is nothing but an approximation of “truth” about the system under consideration.

[@piechulla1966]

C++ has always been complicated. And the development goes on and on. Stroustrup does not exactly stand out as a brakeman. The question is how "modern" your code should be. If you run a static code analysis according to the C++ Core Guidelines against a 30 year old code base: 10000 to 20000 warnings are nothing special there. The idea of what good C++ is has changed over time. Because C++ is always evolving, you have to consider how "modern" you can afford to be. And whether it really makes a difference. I don't rewrite proven legacy code just for fun. You don't have that much time. But sure: A tool that checks your code against the C++ Core Guidelines is of course a blessing! I can't imagine doing without such tools anymore.

The story of the creation of c++ is amazing. Such a humble person created one of the most important programming languages that are used in so many places. For more than 30 years c++ did not have real challengers for certain tasks and even though Stroustrup himself notices that languages like lisp, python, javascript, etc... are great for certain things but sometimes you need that zero-overhead abstraction to write reliable and efficient software. The only real challenger we currently have is rust which proposes really interesting ideas, I guess only time will show how useful of tool rust will become but it seems great that innovation on that front did not stop.

Too bad we didn't had the podcast in time for John McCarthy or Dennis Ritchie =/. On the other hand, Lex's work it's being far better than we could expect, every week.

We gotta get Gerald Sussman, Rob Pike, and Ken up here as well.

[@rahulvig5298]

[@samiehessi8163]

Those diagrams and crops from wiki/webpages are great too. Thanks for the extra work!

Loving the passion Bjarne is exuding during this interview!

[@erkanen]

So much wisdom there. Incredible conversation!

[@nickbelanger5225]

Wow! I've always been a fuge fan of Bjarne as I use C++ on an almost daily basis as an engineering student, and I love it. This is gonna be good!

[@kilocide6242]

I'm only a few minutes in but I just realized I'm watching a podcast where the inventor of c++ is talking about programming in the early SIXTIES. My mind is blow.

[@frankthefrank641]

Thank you Lex for this fascinating conversation with such a brillant mind

[@i.katsantonis1378]

So interesting and enjoyable, I'm a bit saddened I have finished this podcast. Thank you both!

[@kazwalker764]

I was surprised that the functional languages got many mentions and that telecom as a use case was brought up quite a bit, but there was no mention of Erlang. Either way, this is amazing to listen to.

One of, if not THE, most significant conversations on software engineering principles and philosophy I've had the pleasure of listening to. Very well done, as relevant today as it was when originally recorded.

[@hank-uh1zq]

I love these interviews. You get to understand the human behind the design

[@Andreas-yy8uk]

Never written a line of code in my life. Still listened and loved the entire podcast. Thanks to Bjarne and Lex

[@edenalmakias817]

Great interview! This guy is really good at speaking and expressing himself.

[@user-qy2wf2lt6v]

Mr. Stroustrup! Thank you for you contribution to computer science!

[@KerryOConnor1]

he seems quite pleased by the intelligent questions, it's charming. i've been waiting for the right moment to crack the C++ book on my shelf.. i sense it's time has come

[@TheNishant1980]

Lex you are yourself a legend. Please publish an interview of yourself as well someday. Like me, lot many people will be interested to know as to how you are able to pose such intelligent questions to all these legends 😊

[@guillermotomasini]

I like what he says about simplicity, that applies to everything in engineering.

[@nishanth6403]

@pedro gomes I like C++ but ngl this is true lmao

Damn u Lex, I was going too sleep after a long day at work.

Brilliant interview and brilliant channel, thanks. I don't know if it's actually doable but please consider an interview with Ken Thompson!

[@mexico14000]

The man who made my CS experience a living hell, but proved useful on the long run.

[@amotorcyclerider3230]

20 years back, I had communicated with Bjarne Stroustrup with a question on virtual functions, virtual table, pointers. Within a few weeks he responded with a detailed email. I wish I had saved that email. His response helped and vouched to prove my solution was right back then while the client argued it was not. Looking up functions in a virtual table vs direct call. There is always a cost for flexibility. It all depends on the use case (or user story) and the scenario. Anyways, It was a great feeling to be able to directly communicate with the C++ Guru and get a response back with detailed explanation who agreed with my perspective. Nowadays, there are not many who knows what is Dynamic Binding and Polymorphism (or even heard about it) while it plays a vital thing in AI.

[@bloodycrepe]

Isn't polymorphism one of the core concepts of OOP? I don't think I've ever met OO programmer who did not hear about it. That statement makes no sense.

[@dispatch3499]

Programming: Phase 1: Being able to get away from machine code to more abstracted code based on pure mathematics. Phase 2: Adding types and scope. Phase 3: Inheritance and runtime polymorphism....

[@FabianBarajas]

Stroustrup seems like quite the character. Good sense of humor.

[@TheMateusrex]

Fantastic work! This is the best podcast. Intelligent, interesting guests with an intelligent, interesting interviewer. p.s. I love Bjarne.

[@tytrdev]

I like that he's basically describing rust's ownership semantics when he talks about rules/guidelines coupled with static analysis.

[@gickygackers]

No he wasn't
