CppCon 2019: Jason Turner “The Best Parts of C++'

—

C++ is a big language, and it gets bigger every year. Is C++ it too big? Do we just continue to make the language harder to learn? Or, perhaps, do these language additions actually make the language better and easier to use? We will take a pragmatic look at the changes brought to C++ over the years and what impact they have had on how we write code.

A talk like this should exist for every language!

[pythagorasaurusrex]

Cudos to Jason. He delivers the best talks of them all. Fun and interesting to watch. Never got bored.

[projectivemotion]

I'm returning to C++ after 15 years of living in PHP and this video explains so many things! Thanks!

This is the 1st Time I've heard a 1hr talk on C++Con!
Thanks, Jason! For your awesome content, and great way of presentation!

[davidm.johnston]

Just starting to learn C++ here. This video gave me a headache, but it was worth it! Thanks

22/7 = 3 <--- A much worse approximation for pi

"Who here is stuck on C++98 ..." I feel you :-)

[scotthinton]

After finally being able to use C++11 for a couple of years, I have no desire at all to go back to C++98/03. Great talk, I'm now using most of these without even thinking about how I would have had to do it (if I even could) in 98/03.

[xdavidliu]

24:08 interesting how the audience member suggested "a functor" due to the mistaken adoption of the term to mean "function object" only in the context of C++, and Jason either wasn't aware of that historical accident (or was aware but was making a joke) and assumed the audience member was talking about the functor of category theory

[AxayJha]

This talk is genuinely awesome and loaded!

[adrianstaniec]

Amazing talk!
Unbelievably informative and concise,
which is so rare nowadays.

[victorshcherbakov]

Thanks Jason for the talk, it's pretty awesome, you covered a lot of parts of the language.

[xdavidliu]

24:55 in line 11 it needs to be "&value) const {" instead of "&value) {", otherwise line 24 won't compile

[saeed]

I don't get it why the code in 10:22 is wrong ? can someone please tell me why ?

[zxnnightstalker]

Other languages should have like this channel.

[__hannibaal__]

For me best book that i learn moor feature is Bjarn C++ Book and Stepanov paper and books. And don’t need more because will speed too much time for some thing and without efficiency >>>.

[haxpor]

For double free problem, only occurs if I disable RVO via compilation flag. At least, I tested it with gcc 9.1.
Good summary on features we can use :)

[simonfarre]

For some odd reason MSVC still can't do auto in function params, while last time I tried on clang it worked just fine. Very annoying.
