This year, CppCon 2020 is going virtual. The dates are still the same – September 14-18 – and we are aiming for the CppCon live event to have pretty much everything you’re familiar with at CppCon except moved online: multiple tracks including “back to basics” and a new “embedded” track; live speaker Q&A; live talk time zones friendly to Americas and EMEA (and we’re going to try to arrange around-the-clock recorded repeats in all time zones, where speakers who are available can be available for live Q&A in their repeated talks too, and we’ll do that if it’s possible – but we’re still working on it!); virtual tables where you can interact face-to-face online with other attendees just like at the physical event; virtual exhibitor spaces where you can meet the folks on your favorite product’s teams to ask them question face-to-face; pre- and post-conference classes; and even the CppCon house band playing live before every plenary session. All talk recordings will be freely available as usual on YouTube a month or two after the event, but everything else above will be available only live during CppCon week.
To whet your appetite for this year’s conference, here’s another of the top-rated talks from last year. Enjoy – and register today for CppCon 2020 – all the spirit and flavor of CppCon, this year all virtual and online!
10 Techniques to Understand Existing Code
by Jonathan Boccara
Summary of the talk:
One of the reasons why a lot of us work in C++ is because there is a huge amount of existing projects written in C++.
But existing code can be hard to understand.
In this presentation, you will learn how to make sense of code quickly, from the general big picture of the codebase all the way down to the little details of the code of a complex class.
The ten rules covered in this session will teach you to:
- start reading code from the end
- identify the parts of code that carry the most information
- locate the code of any feature visible in the application
- and many more!Code reading techniques usually come with years and years of experience. This presentation will teach some of them to you right now, supported by code examples.
There is a wealth of talks about how to write C++ code using the latest features of the language, but there are very few talks about reading existing code. In particular the everyday code that people have in their codebases. And as the saying goes, code is read much more often than it is written.
This presentation aims at filling this need in a practical way, by exposing 10 techniques that conferences attendees can use on an everyday basis to understand quickly the code they get to work on, as soon as they go back to the office after the conference.

Naming is Hard: Let's Do Better
by Kate Gregory
Summary of the talk:
C++ developers are famously bad at naming: our idioms, guidelines, and lore are rich in examples of terrible names. For example, consider RAII, which stands for scope bound resource management, or west const which perhaps should be const west, or all the samples that feature an object called x which is an instance of a class called X, and so on.
The good news is that naming well is a learned skill, and you can learn it, and start to name better right away. In this talk, I'll tell you why names matter, what benefits a good name can bring, and how to be better at naming. I'll discuss some categories of names and some common decisions within those categories. I'm not going to give you a set of rules to follow: this is about thinking and considering the meaning of the things you are naming. I will give you some questions to ask yourself and some structure that I use to help me to help those who read what I write.
I'll also address renaming things in existing (legacy) code, why and when to do it, and why getting it right the first time may not even be a realistic goal. You should be a lot more confident naming things after we spend this time together.

There Are No Zero-cost Abstractions
by Chandler Carruth
Summary of the talk:
C++ is often described as providing zero-cost abstractions. Libraries offer up facilities documented as such. And of course, users read all of these advertisements and believe that the abstractions they are using are truly zero-cost.
Sadly, there is no truth in advertising here, and there are no zero-cost abstractions.
This talk will dive into what we mean by "zero-cost abstractions", and explain why it is at best misleading and at worst completely wrong to describe libraries this way. It will show case studies of where this has led to significant problems in practice as libraries are designed or used in unscalable and unsustainable ways. Finally, it will suggest a different framing and approach for discussing abstraction costs in modern C++ software.

Converting to C++20 Modules
by Nathan Sidwell
Summary of the talk:
C++20 will have a module system, which provides benefits beyond simple code hygiene. C++20 modules uses new keywords and explicit source-level annotations. How do we get there from here?
I have been implementing this in the GNU compiler, and will talk about the broad strokes of the module specification.
I will describe how:
* one may incrementally convert source code,
* build systems might be augmented,

Maintainability and Refactoring Impact of Higher-Level Design Features
by Titus Winters
Summary of the talk:
Higher levels of abstraction are useful for building things out of, but also have a higher cognitive and maintenance cost. That is, it's a lot easier to refactor a function than it is to change a type, and similarly easier to deal with a single concrete type than a class template, or a Concept, or a meta-Concept ... In this talk I'll present example strategies for refactoring the interface of functions, classes, and class templates. I'll also discuss how the recent addition of Concepts and the proposals for even-more-abstract features affect long-term refactoring in C++. If you're interested in refactoring and it isn't immediately clear that a Concept published in a library can never change, this talk is for you.

Back to Basics: Const as a Promise
by Dan Saks
Summary of the talk:
The const qualifier has various uses in C++. One of the most valuable uses is in declaring function headings that constrain the effects of function calls. Using const appropriately can reduce bugs and development time by turning potential run-time errors into compile-time errors that are much easier to find and correct. Using const can even reduce your program’s code size and execution time.
Despite these benefits, too many C++ programmers still use const reactively rather than proactively. That is, they tend to add const as needed to quell compiler error messages, rather than design const in as they code. To get the most out of const, programmers really need to understand (1) when and where to place const in declarations, (2) when to leave it out entirely, and (3) how type conversions involving const behave.
The key insight about const is to understand const as a promise—a promise not to modify something. This session explains the real meaning of that promise and how that insight can guide you in declaring function parameters and return types. It also explains why you shouldn’t declare by-value parameters and return types as const, why overloading on const is such a useful and ubiquitous idiom, and why it is meaningful to declare constexpr member functions as const.

Range Algorithms, Views and Actions: A Comprehensive Guide
by Dvir Yitzchaki
Summary of the talk:
STL algorithms are something every C++ programmer should know. With ranges being voted in C++ 20, there are even more useful tools that we should at least be aware of, if not use daily.
Using ranges helps writing a code which is great in expressiveness and safety and does not fall behind in performance. In this talk we will cover what ranges add to the C++20 standard library, as well as go over all the different views and actions available in range-v3 library which can be used today.
This talk is inspired by Jonathan Boccara’s talk "105 algorithms in less than an hour".
