Using GitHub Actions for Continuous Integration
by Richard Thomson
From the video description:
GitHub actions allow you to set up continuous integration for your C++ project. You can configure, build and test your code in a variety of operating systems and hardware configurations.
This month, Richard Thomson will give us an introduction to GitHub actions for continuous integration of C++ projects. We'll look at how to set up automatic building and testing of code on various repository events, such as commits, pull requests, and so-on.
Some of the topics we will cover are:
- How to configure GitHub actions from scratch
- How to use some continuous integration project templates
- How to run tests
- How to integrate custom build/test environments

Back to Basics: Debugging in C++
by Mike Shah
Summary of the talk:
I always tell my students, the debugger is your 'get out of jail free card' when working on a project. I say the same thing to professionals, debuggers are your 'get out of free jail card'. The reality is that programmers spend the majority of their time debugging as opposed to writing new code. Unfortunately many programmers do not learn how to use a debugger, or otherwise how they should approach debugging. In this talk I am going to show you how to debug C++ code, starting from the very basics and then demonstrating how a debugger like GDB can be used to help you track errors in CPU code. Attendees at this talk will learn names of debugging techniques (e.g. delta debugging), and I will demonstrate several debugging tools (stepping through code, capturing backtraces, conditional breakpoints, scripting, and even time traveling!) to demonstrate the power of debuggers. This is a beginner friendly talk where we are going to start from the beginning, but I suspect I may show a trick or two that folks with prior experience will appreciate.

C++ Lambda Idioms
by Timur Doumler
Summary of the talk:
Ever since they were introduced in C++11, lambdas have been an essential language feature. Each subsequent standard added more functionality: we got generic lambdas and init captures in C++14, constexpr lambdas in C++17, default-construction and assignment, explicit template arguments and more in C++20, and even more possibilities are coming in the upcoming C++23 standard.
In this talk, we are looking at various interesting things you can do with lambdas. Some of these are well-established, useful idioms; others are lesser known, surprising tricks. Have you ever inherited from a lambda? Can you think of three different ways to call a lambda recursively? Do you know what happens if we assign an immediately-invoked lambda expression to a static variable? If not, then this talk is for you.

C++ Coding with Neovim
by Prateek Raman
Summary of the talk:
If the command line has ever piqued your interest, specially using Vim/Neovim for C++ coding, but you have some reservations about losing access to IDE like features, wonder no more. This talk will present a productive C++ development environment on the Command Line using Neovim and LSP. LSP (Language Server Protocol) is the protocol which powers semantic auto-completion and intellisense in modern IDEs and we'll learn how Neovim's built-in LSP client integrates seamlessly with language servers to provide a rich editing experience.
Neovim is a modern editor built on top off the giant shoulders of Vim, and lets us have all the speed and efficiency of Vim as we edit code, while also providing rich support for C++ coding with intellisense and auto-completion via LSP. Along the way we'll also demonstrate Neovim's rich LSP aware plugin ecosystem for project navigation and IDE like workflows, all on the command line.
Even if you're comfortable with Vim/Neovim, but would like to learn how to level up the experience with modern IDE features, you will find this talk interesting.

C++23 - What's In It For You?
by Marc Gregoire
Summary of the talk:
C++23, the next release of the C++ standard, is scheduled to be released in 2023. The update introduces new features to the core language and to the Standard Library. If you want to stay up to date with the latest features that are upcoming with this new release, then this session is for you.
The session includes core language topics such as consteval if statements, multidimensional subscript operators, decay copy, unreachable code, and more. New Standard Library features that will be shown include monadic operations for std::optional, std::flat_map, std::flat_set, a stacktrace library, changes to the ranges library, improvements to std::format, std::expected, and many more.
The session will include references to other sessions at CppCon, if applicable, for more deep-dive information on any particular topic.

The Most Important Optimizations to Apply in Your C++ Programs
by Jan Bielak
Summary of the talk:
Writing efficient programs is hard. This is because it requires a lot of knowledge, experience and strategic thinking. There have been many talks on optimization and often each addresses a single concept. Being able to achieve a bird’s eye view of factors affecting performance often requires many hours of researching the topic. To lessen the mental burden of optimizing programs, I have picked out the techniques, I believe are most important. During the talk, I will present them in an organized manner and provide practical examples of how they can be applied.
I will first discuss what I believe are the main goals efficient programs strive to achieve. Then, I will present the general methods of achieving those goals. Then, for the majority of the talk, we will discuss a few dozen performance opportunities. For each of them, I will explain the underlying mechanism of how the optimisation works. I will avoid bluntly giving guidelines to follow without explanation. Each of the techniques naturally comes with its costs, and those will be discussed as well.
I will additionally discuss various performance pitfalls. These are sometimes called “premature pessimisations” in contrast to the often used term of “premature optimizations”. I will show examples of optimizations which do not incur any cost on program readability or maintainability and as such should be considered performance best practices. Avoiding their use doesn’t improve code in any manner, while making it slower.
This talk is intended for a diverse audience, as after all, probably most of the C++ community is interested in performance. It is appropriate for hobbyists and professionals alike, with varying experience with the language, due to the gradual increase in difficulty of examples. It will be a time productively spent.

Lightning Talk: Const Mayhem in C++
by Ofek Shilon
Summary of the talk:
Did you know that:
(1) const methods can legally modify members?
(2) A const object cannot be default-initialized? (this makes sense after a minute)
(2)(b) Unless... a default constructor is declared non-inline?
(3) The standard does not properly account for volatile members of const objects?
All this and (probably not much) more, at this lightning talk.
