Churchill College Annual Computer Science Lecture - Bjarne Stroustrup: C++ Today

[@paulchoudhury2573]

Great talk by one of the few people in software development I will unconditionally trust.

[@letoatreides6086]

Dear Bjarne, I love C++. Didn't start with it but C then Java. And, sadly, I don't use C++ at work, but the most recent versions of C++ since 2011, they're a marvel to use. I am absolutely in love with C++ 2014 and versions after that one :)

[@Vekkq]

Or you could just pick the real thing, from which many of these new features got derived from: Haskell.

[@imte13]

Our father :)) Author of C++, without him, no games of today :D

[@ahmadnikidoskaufmann]

Tatu Eugen ooohh

[@zsaklinhorvath8548]

ahmad nikidos

[@Dasdasd0]

Fantastic man. He demands no sacrifices in simplicity and efficiency and that's truly inspiring.

[@feastures]

What do you mean, C++ is not simple at all and has efficiency as the root of evil (see Donald Knuth).

[@akshayazariah]

Once you learn C, it is easy. Very easy. Or you can learn it the hard way. www.sololearn.com/Play/CPlusPlus/

[@digimikeh]

if you know how to program in C# . isn't too hard too.

[@dennisschagt]

I guess this is the paper which is mentioned at 13:00 - www.stroustrup.com/resource-model.pdf

[@FiePelows]

Thnx !

[@TEKRific]

4 yrs late to the party but tanks so much for the link. Interesting paper, very clarifying and instructive!

[@digimikeh]

is there any reason to use c++?.. YES.. it is in everything you look on technology... every machine has a program. and it is highly probable wrote in c++

[@dmaster20ify]

The man said that they will reach one million lines in the next year. One million line is required for their program!

[@julianacienfuegos2370]

I would like to see what this man looked like with hair

[@hujidzicu]

on his earliest images he looks the same; I think he's born with that hairstyle :D

[@CharIie83]

I would love a generic pointer-type to methods. So that I can easily make a scheduler with every method that I want to call in the same vector, regardless of what objects method is being pointed to. Maybe I'm missing something, but I cant find this built in anywhere. Im certain it can be done too, as I'm writing accessor functions to make the same thing happen manually. (a pointer to a function, that itself calls a specific method, so I don't have to statically iterate over the multitude of methods that my scheduler might want to call.) Am I alone in thinking this would be useful? Maybe there is a different, better solution that I haven't found. Anyways, nice talk =)

[@brunomanganelli2456]

have you tried std::function with lambdas?

[@CharIie83]

Too complicated basically. I feel like being able to store method calls in a vector shouldnt be this complicated is all im saying. I will look more at your suggestion tho, it seems to be very close to what I'm looking for

[@MurrayCumming]

sigc::slot from libsigc++ can do that.

[@kwanarchive]

Not really that complicated. std::vector of std::functions is child's play.

[@CharIie83]

I wound up using unique_ptr with shared base access btw. The thing is I need a way to refer to the methods themselves, regardless of what struct/class they belong to

[@ingeborgschmidt-huser9299]

loved it.

[@LeeCoangSee]

smartest man alive

[@zeuglcockatrice4633]

not for long

[@DupczacyBawol]

This is the man who invented A CLASS - objective data type, used in almost every "beautiful" programming language nowadays :) Thank you Mr. Stroustrup and thank you KZbin.

[@kubixus]

He did not. C++ isn't the first objective programming language.

[@LuisHenrique-wb8pv]

He isn't, but he still a badass.

[@Conenion]

en.wikipedia.org/wiki/Simula already had classes and all that fancy OOP stuff back in 1965(!).

[@kwanarchive]

Not correct, but classes are overrated. The man invented templates and accidentally embedded a separate Turing complete language at compile time. It doesn't cost anyone to have it in there, but the stuff you're able to do with it is beyond compare. It's even better than LISP macros.

[@ClandestineLodge]

A class is simply a classification (such as a classroom dedicated to a specific topic). People have been classifying, organizing and grouping things for a long time. There are systems such as the Qabalah that are every bit as sophisticated as anything used by modern programming languages. One can find interesting parallels with Object Oriented Programming and Plato's Republic (as just one example)...

[@datpham31415]

what did he mean " no language is perfect" ??

[@clodgozon3968]

3:35 perfect for scaring children.

[@bolow]

How do pronounce his name?

[@digusdreamgallery2211]

Biyarne-strovv-strup

[@Knuckler]

It's on his FAQ - www.stroustrup.com/bs_faq.html - ctrl-F "pronounce", or scroll down slightly, it's the first question

[@mjsanchez2173]

Why does this man whistle when he talks ?

[@isukanne6885]

MJ Sanchez Sound is bad

[@datpham31415]

any languages can do it !!

[@LukasanaTK]

Genius

[@feastures]

I call C++ insanity.

[@tombil-certon]

@@feastures the line between insanity and genius is very blur

[@QuentinUK]

That is not the stars.

[@KevinKuruvillaPianoCovers]

[@feastures]

Simple a case of selection bias (en.wikipedia.org/wiki/Selection_bias), only people that 'love' this horrific programming language will watch.

[@achmadfathoni3944]

feastures You are new in c++ , aren't you?

[@dmaster20ify]

Why is it that new programming languages keep on changing and the need for new programming languages. I mean I thought that I would use a language and make any software that I feel. Ok. people are complaining about the ease of making certain softwares with certain languages. Alot of persons complaining that C++ is too hard. I just consider them lazy and not equipped. Like if you use something like Java, the language has pre - built functions that does most of the work for you. I am not a programming expert right now; but I think Java's ability to make code is limited; and a language like C++ can make program. This is my hypothesis. Furthermore Java is fucking slow. Jar games are slow, Java to watch videos and play online Java games load slow and use up memory.

[@Uni-Coder]

Well, really, we should do respect to C&Cpp but their age goes away, new languages and new ideas come to be great and famous.

[@angistron]

Hahaha, good one.

[@ITR]

Though I don't think Cpp will go away any time soon (Especially since c++ is still updated), there are some great new languages too.

[@nicolareiman9687]

u know nothing about IT industry

[@sethother8012]

Lamest. Audience. Ever. They don't even laugh at his opening jokes. Poor guy. lol

[@kasozivincent107]

This dude forgot about belts 😂😂

[@paulfunigga]

shame on bjarne for that sequence example, there's division by zero after his return statement

[@carbonquiznoz1]

Paul Orekhov ok

[@gblargg]

[@teemoonduty4945]

garbage collection is not enough!

[@kwanarchive]

Well, no. Herb Sutter himself gave a talk at last year's CppCon about a resource manager he created, which turned out to be a garbage collector. Only it's a C++ garbage collector, so it does more than memory cleanup, and is much better than current garbage collectors.

[@feastures]

All we need is C++ to garbage collect itself.

[@dertechl6628]

who needs a GC if there's RAII?

[@dildarsk246]

5 fucking javascript,python coders found.

[@chimpionboy]

Loll.

[@jptbaba]

Thanks for creating a horrible language!

[@Alex-ht1oq]

jptbaba why are you here then ? Just unnecessary.

[@ITR]

Why do you think c++ is a horrible language? xD

[@jptbaba]

Linus torvalds said so thats why.

[@ITR]

jptbaba So you blindly follow everything Linus says without looking at his reasons for why? :-P

[@aldrinaldrin4618]

Linus said it... in his kernel's performance perspective.

[@datpham31415]

bill gates let others develope it !!!

[@feastures]

Talking about garbage collection: C++ is a collection of garbage.

[@thepdg5160]

feastures What's wrong with you? Why do you hate on C++ and have the desire to spread that hatred?

[@pseudorealityisreal]

Yeah, he is a troll. C++ is hard, but rewarding. Guess this troll doesn't like hardwork.

[@socrattt]

are you bad at programming?

[@gblargg]

Given the requirements, what design do you think would better meet these?
