As simple as 1 + 1 = 2 ? - Loïc Joly - CPPP 2021

Do you know how integer arithmetic works in C++? Do you really know? For my part, the more I know about it, the more I discover how much I did not know, and I'm truly grateful that most of the time, it just works. In this lightning talk, I present a quiz about a simple addition that can give surprising results, when it doesn't just work.

SIMD in C++20 - EVE of a new Era - Joël Falcou - CPPP 2021
มุมมอง 3862 ปีที่แล้ว
github.com/CpppFr/CPPP-21 cppp.fr/ In those days and ages of GPGPU, Cloud Computing, and other bleeding-edge large-scale computing architectures, peoples often forget that 150% of their CPU comes with a layer of Instruction Level Parallelism: their SIMD computing unit. If writing code using SIMD systems was less of a nightmare then, yeah, people would use it. So, obviously, we had to write a li...

A brief introduction to Time Travel Debugging - Chris Croft-White - CPPP 2021
มุมมอง 4782 ปีที่แล้ว
github.com/CpppFr/CPPP-21 cppp.fr/ Time travel debugging enables developers to record an application as it's running - capturing the state of the application at every instruction - and then rewind and replay to inspect program state at any point in time. It's a bit like replaying a CCTV tape to see what happened. Watch this lightning talk to see how this works in practice. Chris Croft-White Chr...

Correctly Calculating min, max, and More - Walter E Brown - CPPP 2021
มุมมอง 2962 ปีที่แล้ว
github.com/CpppFr/CPPP-21 cppp.fr/ The C standard library long ago selected operator < as its ordering primitive, and even spells it in several different ways (e.g., std::less). This talk will explain why operator < (and its aliases) must be used with care, in even such seemingly simple algorithms as max and min. We will also discuss the use of operator < in several other order-related algorith...

มุมมอง 3832 ปีที่แล้ว
github.com/CpppFr/CPPP-21 cppp.fr/ Some people want to use the latest version C with all the bells and whistles. Some like it for only a few aspects, and would love to forget about the remaining parts. But is that possible? The answer is yes, and from freestanding C to a range of compiler flags, many a project do use C like this. Let's discover these choices and explore the consequence! Serge G...

What Classes we Design and How - Peter Sommerlad - CPPP 2021
A well-balanced, well thought-out, level-headed and detailed talk. Feels like being guided through a thesis on iterator styles. We've all been frustrated at the complexities and limitations of C++ iterators, and wondering what the alternatives are -- this talk gives you that knowledge, and lets you appreciate each point in the design space.
27:30, so are ranges slow in any language? 38:22, C++ is faster for most cases and, as long as I know/think, it's also better to build tools - _or is Rust better to make C++ things than the opposite_ ? 57:52, tsc, tsc, tsc... I guess the answer is here, for example. I appreciate C++ functionality even more than its speed.
I keep getting function definition for INSTANTIATE_TEST_CASE_P not found. I am sure the variables are correct but it still will not recognize it.
We could've defined constexpr int I = 1; constexpr int J = 1; leading to preprocessor not seeing the definitions while evaluating #if I + J == 2u to get the same "2 Not 2" output. Getting "2 2" is trivial.
I believe in the `write2Decimals` function should be `+ 2*n` instead `+ n` ?
Yes, you are right.
Enjoyed your presentation on code as an artist medium. Truly leads to a discussion on what is... and how is...! I disagree with that mathematician's quote of listening vs doing. I think the bigger point is level of involvement as the consumer versus being the creator of the content. I did really like the "proofs from the book" ideas. Paul Erdos still having an effect on art and science. So many aspects to consider when thinking about Aesthetics.
For backwards compatibility, can you beat Fortran? Still can compile early 70s FORTRAN IV code…
I am also a Matt, and I also played and administered muds at around the same time (although ours were Envy-based rather than ROM based), and even today I have a fondness for Telnet and terminals. Awesome stuff!
Fantastic! Thanks for sharing :)
Matt playing MUD? Gold
Thank you, this was entertaining as well informative!
Oh, lovely, DikuMUD. The source code license that will take you to court for having a donation link for server costs in your game.
I didn't know Bruce Dickinson was a C++ programmer.
Diku was probably the grandfather of MUDs; I think almost every MUD was based on it. I'm glad that Matt let me time travel a little bit back to my youth and think about MUDs :)
Glad to give you that nostalgia buzz!
