Sean Baxter demonstrates memory safe C++ using his Circle compiler
Safe C++
Sean Baxter
From the talk:
Does a subset of a superset of C++ exists that achieves similar safety guarantees to rust, is useful and expressive enough, and is compatible with today's C++? If so, is anyone mad enough to do it? There is an answer to that

Lightning Talk: Let's Fix Sparse Linear Algebra with C++. It'll Be Fun and Easy!
by Benjamin Brock
Summary of the talk:
Sparse linear algebra is hard. There are a large variety of different sparse linear algebra formats, and they all require obtuse index arithmetic in order to use. But what if we could fix this? In this talk, I'll present an idea for "fixing sparse linear algebra" using customization points, the ranges library, and high-level multi-dimensional iteration.

Lightning Talk: Implementing Coroutines Using C++17
by Alon Wolf
Summary of the talk:
In this lightning talk, we will explore the journey of implementing coroutines in C++17 before they were added to the language in C++20.
The implementation uses macros, template metaprogramming, assembly functions, and more that resulting in working coroutines despite somewhat "horrible" code.
Discover how local variables within the coroutine body were leveraged to calculate frame sizes and ensure correct variable lifetimes during suspension, resumption, and destruction.

C++ Memory Model: from C++11 to C++23
by Alex Dathskovsky
Summary of the talk:
In the realm of C++ development, threading and memory management play a crucial role in crafting highly parallel and optimized programs. However, the absence of a memory model in C++98 posed challenges. Thankfully, with the advent of C++11, significant changes were introduced, including the introduction of a memory model, which brought forth a plethora of new and exciting tools for developers to leverage. This talk aims to delve into the realm of the C++ memory model, showcasing the arsenal of tools at our disposal. Attendees will gain insights into how CPUs and compilers optimize code and understand the criticality of adhering to the memory model correctly. Practical guidelines on utilizing these tools effectively will also be explored.
Throughout the talk, we will illustrate practical examples and share best practices for utilizing the diverse set of tools now available to us. From atomic operations to memory barriers, we will explore the range of techniques that allow us to develop robust and thread-safe code.
This talk will also illustrate the newer tools from newer C++ standards like JThread and so this talk will show how memory model is used and how it advanced since C++11.

Lightning Talk: Help! My Expression Template Type Names Are Too Long!
by Braden Ganetsky
Summary of the talk:
Even the name of this talk is too long! If we're ever working with expression templates, we can easily make type names long enough to slow down compilation time. Suddenly our "zero-overhead" expression templates start giving a large compile time overhead. I'll show off a C++20 trick to fix this problem.

Lightning Talk: Filling the Bucket: Reading Code, C++ Code Interviews & Exams
by Amir Kirsh
Summary of the talk:
We are going to review and practice a reading code challenge. Reading code skills are quite important, maybe even more than writing code. So let's dive together into filling the bucket code reading challenge!

Back to Basics: The Rule of Five in C++
by Andre Kostur
Summary of the talk:
Designing a class to behave correctly when copied and moved takes a lot of thought. The Core Guidelines provide guidance to streamline that work. In this talk we are going to look at the Core Guideline known as "the Rule of Five", how it came about, and is there anything better.

The U.S. government released a report calling on the technical community to proactively reduce the attack surface area of software infrastructure. Herb tackles the concerns cast on C++ on memory safety.
C++ Safety with Herb Sutter
by Jordi Mon Companys in Software Engineering Daily
From the interview:
It's really, really important as native languages C and C++, not to have our heads in the sand and say, "Oh, well, we've been hearing this for years. All is well." No, it's not. We have work to do. But it's also important not to go to the other extreme, and think that, "Oh, if we just magically wave a wand and make all the world's software, suddenly convert overnight to memory-safe languages", which would be great if it can be done. It's not technically feasible. ut even if we could do that, we're not going to make most of the attacks go away.

Exceptionally Bad: The Misuse of Exceptions in C++ & How to Do Better
by Peter Muldoon
Summary of the talk:
Exceptions were originally heralded as a new modern way to handle errors. However the C++ community is split as to whether exceptions are useful or should be banned outright. It has not helped the pro-exception lobby that in their enthusiasm to embrace exceptions, a lot of code has been written that puts exceptions in a bad light.
In this talk, We will present the original intent/history of exceptions and a brief overview of how exception mechanics work and how they circumvent the usual stack return mechanism to set the stage. we will then examine the philosophy of using exceptions and then the many cases of exception misuse including resource management, retries, hierarchies, data passing and control flow to name but a few.
For each case, we will then suggest better ways to handle each specific situation. In many cases, exceptions are often dropped in favor of some other more appropriate paradigm.
Finally, we will introduce situations that can truly benefit from exceptions and what a model exception class might look like.
