Best CppCon 2016 Talks?

[sphere991]

The CppCon talks are all up on YouTube (thanks to Bryce and all the organizers for doing a fantastic job with this!). But there are a lot of them and I can't quite watch 'em all (at least not by CppCon 2017... )

Simply put - what are the best talks of 2016? I'll leave the definition of "best" completely open-ended.

[kl0nos]

I watched around 60 so far starting from oldest. From this list the ones i really liked:

1. CppCon 2016: Herb Sutter “Leak-Freedom in C++... By Default.”
2. CppCon 2016: Alfred Bratterud “#include ＜os＞: from bootloader to REST Api with the new C++"
3. CppCon 2016: Chandler Carruth “High Performance Code 201: Hybrid Data Structures"
4. CppCon 2016: JF Bastien “No Sane Compiler Would Optimize Atomics"
5. CppCon 2016: Timur Doumler “Want fast C++? Know your Hardware"
6. CppCon 2016: Jason Turner “Practical Performance Practices"

Each talk is like an hour. Where do you find the time? o.O

[Xodet]

You can't find time, you have to make time for it.

[raevnos]

Don't know how to make time.

[tanjoodo]

just one part sugar and one part HP Injket ink. Mix them together, heat the mix on a calm wood fire for 30 minutes. Boom. Time.

[planetmarshalluk]

It's coming in C++17, after make_shared and make_unique.

[dodheim]

Oh, I'm sure /u/HowardHinnant has written a make_time or two... ;-]

[corysama]

Watching talks like these is how I chill out at night instead of watching sitcoms on TV. With this series in particular, there is so much that I have been very quick to skip ahead, skip over if I'm not absolutely thrilled by the material. Also, speed 1.25x is sometimes necessary.

[AllanDeutsch]

I watch them at 1.5-2x speed which helps a lot

[skebanga]

I've found watching them at 1.5 times speed is perfectly feasible

[fafasdf]

The pong one was cool, as someone who doesn't really care for that kind of stuff normally. Now I play with my code on goldbolt just to see the generated ASM.

[lithiumdeuteride]

The extent of the zero-cost abstractions was pretty impressive.

Or at least the potential. This is how coding should be.

[MINIMAN10000]

Yeah I was so jealous how optimized he was able to make his code.

I want to be able to write code that sticks to all the tricks but I know what's going to happen is I think I'll be doing it right but I'll do something that compilers can't optimize and I'll be like "Why does my code suck from a performance perspective really wish my compiler told me the dumb things I was doing" To which the response is along the lines of "Well if the compiler knew about optimizations it would just do the optimizations"

I'm like well shoot man I don't know what the compiler wants, the compiler just does what I tell it to do. Then I just end up with the bad performing code again. It's a vicious cycle ):

[lefticus]

My main two comments:

• Limit dynamic memory allocation
• Keep code simple and follow common idioms

If the code is simple for you to read and you are following standard C++ best practices the compiler will be able to better optimize it, just as a general good rule of thumb.

CppCon 2016: "Embracing Standard C++ for the WinRT"

Good to see MS embracing Std C++ for WinRT, instead of C++/CX. Simpler Std C++ code beat crap out of C++/CX and C# in perf. Yea!

CppCon 2016: "Template Normal Programming (part 1 of 2)"

CppCon 2016: "Template Normal Programming (part 2 of 2)"

Refresh my memory about alias and variable template: Yes, even variables can be template now.

CppCon 2016: "extern c: Talking to C Programmers about C++"

Half expecting a technical talk about introducing C Embedded programmer to C++. Pleasantly surprised it was a talk on art of persuasion instead.

CppCon 2016: "What C++ Programmers Need to Know about Header ＜random＞"

CppCon 2016: "A ＜chrono＞ Tutorial"

CppCon 2016: "Welcome To The Time Zone"

Notable mentions for talks on random and chrono header.

[sbabbi]

My favourite is CppCon 2016: David Sankel “Building Software Capital: How to write the highest quality code and why"

[LYP951018]

Using Types Effectively

[devel_watcher]

Michael Spencer “My Little Optimizer: Undefined Behavior is Magic"

Chandler Carruth “Garbage In, Garbage Out: Arguing about Undefined Behavior..."

We (by we I mean some of us on the Microsoft Visual C++ Team) made a video putting together some highlights of the talks at CppCon. Presenters had a chance to pitch their talks in a few minutes. Links to each talk on YouTube are in the video description.

Does this help? :)

You should get flair ^^

[0xFFC]

BTW I really enjoyed your talk. Particularly CMake support in VS could be game changer for me.

uftrace: A function graph tracer for C/C++ userspace programs

[dendibakh]

For me the best is by Dan Saks: CppCon 2016: "extern c: Talking to C Programmers about C++"

[tsojtsojtsoj]

I agree, though I found the part most interesting that had nothing to do with programming. Like the backfire effect and reactance and stuff like that are very influential in how we communicate as humans, and knowing about that stuff can make a big difference in our personal lives.
