This talk explores how these new algorithms improve code clarity, expressiveness, and performance.We’ll consider the following key aspects:- What Parallel Range Algorithms are, and how they differ from C++17 parallel algorithms and serial range algorithms;- What design choices were made, specifically addressing bounded ranges and range-as-the-output, and some corner cases;- The performance implications of Parallel Range Algorithms;- The safety implications of Parallel Range Algorithms;- How these algorithms apply to heterogeneous computing based on oneAPI DPC++ library (oneDPL) experience.This talk is based on an active C++ standard proposal (P3179) that has strong potential to land in C++26. We will break down key design decisions, explore code examples, and discuss how these algorithms enable more expressive and scalable parallelism in modern C++.While this session will be technical, it is targeted to be accessible to different audiences, from library authors to everyday C++ developers. Expect technical insights, and a look into the future of parallel programming in C++.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Parallel_Range_Algorithms.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Ruslan ArutyunyanRuslan is a Senior Middleware Development Engineer specializing in parallel and threading runtimes.

CPS in Cmake - Marching Towards Standard C++ Dependency Management - Bill Hoffman - C++Now 2025 CppNow 2025-10-02 | https://www.cppnow.org---CPS in Cmake - Marching Towards Standard C++ Dependency Management - Bill Hoffman - C++Now 2025---In 2023, Bret Brown and Bill Hoffman gave a talk at CppCon "Libraries: First Step Toward Standard C++ Dependency Management". This was an introduction to the Common Package Specification (CPS), a specification for the declaration of meta data that can accompany prebuilt libraries with full usage specifications. Prebuilt libraries have existed for decades… they predate C++ even. After all these years, techniques to use prebuilt libraries are still ad hoc and difficult to maintain. A root cause of this variety of techniques is the variety of things that are C++ libraries: header-only libraries, statically linked archives, dynamically linked binaries, and so on. Consuming projects need to build against these libraries in consistent ways or risk catastrophic failure in production environments. This creates enormous interoperability problems across broad portions of the wide programming ecosystem, not just the C++ parts of it.In that talk, there was a promise of using CMake's installation base and existing export/import (in the CMake language) of similar meta data to help promote and test this new specification. Progress has been moving forward, and in CMake 4.0 (released in 2025) an experimental CPS implementation can be found in CMake. This talk will explore the current implementation in CMake. The talk will also cover the ramifications of this new standard on package managers, IDE's, SBOM generation. The talk is intended for anyone who produces or consumes C++ libraries. Special knowledge of C++ tooling, build systems, or package managers is not required.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/CPS_in_CMake.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Bill HoffmanMr. Hoffman is a founder of Kitware and currently serves as Chairman of the Board, Vice President, and Chief Technical Officer (CTO).

How to Pinpoint Runtime Errors in Mixed C++ & Rust Code For Busy Engineers - Steve Barriault C++Now CppNow 2025-09-27 | https://www.cppnow.org---How to Pinpoint Runtime Errors in Mixed C++ & Rust Code For Busy Engineers - Steve Barriault - C++Now 2025---As C++ developers explore Rust for new development, the challenge of interoperability between the two languages grows. Large-scale C++ codebases now integrate Rust, requiring the use of the C ABI, which introduces risks like undefined behavior in C++ and runtime panics in Rust. Today, formal verification is often limited to specific programming languages (Ada, C, C++), with few tools supporting mixed-language environments. As Rust adoption increases alongside C++, new formal verification tools must evolve to ensure safe, predictable interactions between Rust and C++ libraries.This talk explores how formal verification techniques can be adapted to hybrid systems to detect runtime errors both within the language-specific segments and across the language divide. We will also provide a few coded examples to illustrate how formal methods can be leveraged to pinpoint these errors with no false negatives and a low percentage of false positives.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Identifying_Runtime_Errors_in_Mixed_Cpp_and_Rust_Codebases_Using_Formal_Methods.pptxJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Steve BarriaultSteve Barriault is Vice President Technical Business Development at TrustInSoft, the leader in the use of formal methods for the detection of bugs in safety and security-critical applications.

Implementing the C++ Standard Library Proposal for any_view - Patrick Roberts - C++Now 2025 CppNow 2025-09-25 | https://www.cppnow.org---A View for Any Occasion - Implementing the C++ Standard Library Proposal for any_view - Patrick Roberts - C++Now 2025---In this talk, we will introduce a reference implementation for a proposed addition to the C++ standard library: std::ranges::any_view. This new type provides a flexible, generalized, type-erased view that can wrap any viewable range object. The any_view abstracts away the specific concrete type of the underlying container, allowing developers to define appropriate API boundaries for range adaptor pipelines. We will explore a design and implementation of std::ranges::any_view added to the Beman project, demonstrate its usage with real-world examples, and discuss how it fits into the broader context of C++'s evolving ranges library. Attendees will learn how this feature can enhance the expressiveness and reusability of their code, while maintaining performance through optimized type erasure. Additionally, we will delve into the trade-offs and challenges faced during its design and implementation, including type safety, efficiency, and compatibility with existing ranges features. This talk will provide insights into the practical applications of type-erased views and offer a glimpse into the future potential of range-based programming in C++.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/A_View_for_Any_Occasion.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Patrick RobertsPatrick Roberts is a licensed professional engineer who graduated from the University of Houston with a Bachelor of Science in Electrical Engineering in 2017.

What can we do to reduce this barrier to entry? In this talk we'll discuss the design of a refactoring paradigm that makes C++ refactoring tooling accessible to the general C++ developer. Rather than needing to learn bespoke APIs, or gain familiarity with the idiosyncrasies of Clang's AST, developers can simply write examples of the code patterns they wish to detect and the replacements they wish to generate in everyday C++. This enables a background task to generate, test and apply refactorings, freeing developers to work on more complex and business-critical tasks.---Slides: https://brontosource.dev/short/bb3a10e9Join think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Andy SofferAndy Soffer is a lapsed mathematician turned software engineer.

Balancing the Books: Access Right Tracking for C++ - Lisa Lippincott - C++Now 2025 CppNow 2025-09-15 | https://www.cppnow.org---Balancing the Books: Access Right Tracking for C++ - Lisa Lippincott - C++Now 2025---Writing a well-functioning computer program is an exercise in following rules. Complying with the rules is made much easier when a program can verify its own compliance. This is why we write assertions: they express the rules we wish a program to follow in a way that allows the program to verify its compliance.But assertions are limited to a particular kind of rule: the rule must be parameterized only by the data the program has at hand. Assertions work wonderfully for “don’t divide by zero,” but they struggle with “don’t read from an uninitialized object” or “don’t write past the end of an array,” and fail entirely with “don’t destroy an object twice” or “don’t write to an object from which another thread might be reading.” The information needed to verify compliance with these rules is simply not available.So let’s make it available! Let’s try writing extra declarations into programs, and recording the information needed to verify compliance with all the rules. This is, of course, what sanitizers attempt to do. But for compatibility, sanitizers rely on a great deal of guesswork, particularly about objects accessed from more than one translation unit. By providing extra declarations, we can make our intent clear and take the guesswork out of verifying code.These new declarations form a bookkeeping system for our program. By keeping balanced books, we can detect imminent violations of our programming rules, and head off much undefined behavior before it happens. In this lecture, I will explore the details of this bookkeeping system.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Balancing_the_Books.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Lisa LippincottLisa Lippincott designed the software architectures of Tanium and BigFix, two systems for managing large fleets of computers.

In 2020, “P1683R0: References for Standard Library Vocabulary Types - an optional＜&＞ case study” surveyed existing behavior of optional references in the wild, and pointed out the trap of assignment behavior being state dependent. In 2023, “P2988R0: Std:Optional” picked up the torch again, and Revision 9 of that is the proposal that is design-approved by the Library Evolution Working Group.In 2024, “P3168R0: Give Std:Optional Range Support”, the proposal to make optional a range -- as opposed to having a separate range of zero or one -- was adopted. The reference implementation for optional＜T&＞ and the test cases for views::maybe were used to vet the additional interfaces for optional range support. This merged implementation became one of the first Beman libraries, where the library and the optional reference proposal benefited immensely from the visibility and feedback.The core of the difficulty has been that references are not values, and that types containing a reference do not have value semantics. References do not fit comfortably in the C++ type system. The core value semantic type that also has reference semantics is a pointer, but pointers have under-constrained and unsafe semantics. The lengthy discussion has been a proxy for what reference semantic types should look like in value semantic types within the standard library, particularly for "sum" types, like expected and variant, but also for types, such as single.This talk will discuss the ISO Standards Process, Project Beman, Value and Reference Semantic Types, Sum and Product Types, CoData, and Lifetime Safety, among other topics.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/std_optional_T&.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Steve DowneySteve Downey has been a programmer for more than 30 years.

By creating reusable, lazy-evaluated views that operate on ranges, developers can avoid unnecessary intermediate containers and simplify complex data transformations. While standard views like std::views::transform and std::views::filter offer powerful tools for basic operations, custom views provide additional flexibility, allowing developers to create highly specialized transformations and handle more complex, state-dependent logic. Through real-world examples, we will demonstrate how custom views enhance performance and maintainability, showcasing how they can streamline everything from basic filtering to complex, state-dependent transformations in modern C++ applications.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Advanced_Ranges.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Steve SorkinSteve Sorkin has been at Bloomberg since 2019, where he is a software engineer working on Bloomberg’s Execution Management System (EMSX) as part of the Portfolio Trading Engineering team.

Cortex.cpp is an open-source engine to run AI models on everything from Raspberry Pis to industrial robots without breaking the bank. This talk goes over how AI models work on different hardware from a C++ perspective, different ways of using Python from within C++ and vice-versa, and how to enable near-metal performance through aggressive bit manipulation, custom memory allocators, and SIMD optimizations. We will also go through the architecture of Cortex and compare it to different C++ implementations while highlighting the tradeoffs we have been making along the way. If you're interested in pushing the boundaries between AI and constrained hardware or just want to see how far you can stretch a bit, this session will show you how we're giving everyday devices the gift of intelligence, one carefully-aligned memory block at a time.---Join think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Ramon PerezRamon is a research engineer and educator working at the intersection of AI and robotics at Menlo Labs.

Extending std::execution - Implementing Custom Algorithms with Senders & Receivers - C++Now 2025 CppNow 2025-08-20 | https://www.cppnow.org---Extending std::execution - Implementing Custom Algorithms with Senders & Receivers - Robert Leahy - C++Now 2025---P2300 introduces `std::execution` and the Senders & Receivers (S&R) model as a new paradigm for expressing asynchronous computation. `std::execution` specifies a fixed set of algorithms that, in some sense, define the baseline DSL of S&R, but this set is not exhaustive. Extending it to cover new use cases is possible, but the standard provides no guide to doing so, because the standard is not a guide.This talk will detail the process of adding a new S&R algorithm by examining the implementation of `when_all_range`, a variation of `when_all` which is part of `std::execution`. Through this example, the audience will see how transformations and control flow can be expressed within `std::execution`, how new algorithms fit into the broader execution model, and what considerations ensure they remain efficient and composable.By the time they leave the talk, attendees will have a clearer understanding of how to extend the S&R framework and implement `std::execution`-based algorithms that integrate seamlessly with modern C++ codebases.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Extending_std_execution.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Robert LeahyRobert is a graduate of the University of Victoria where he specialized in graphics, gaming, and digital geometry processing.

Missing (and Future?) C++ Range Concepts - Jonathan Müller - C++Now 2025 CppNow 2025-08-16 | https://www.cppnow.org---Missing (and Future?) C++ Range Concepts - Jonathan Müller - C++Now 2025---Iterators and ranges have been essential parts of the C++ standard library since its inception. With C++20, they were brought to the next level in the form of `std::ranges`: We now have formalized requirements on the algorithms, lazy views to enable pipelines, and much more powerful iterators. Since then, more and more views and algorithms have been added in C++23.However, the fundamental concepts have mostly been left unchanged, even though there are still some rough edges. This talk explores new kinds of ranges that are not possible with the existing C++ range concepts. We will first look at compile-time-sized, approximately sized, and infinite ranges, then at noncontiguous ranges with contiguous chunks. Finally, we will explore an optimization to make many algorithms much more efficient by using a pushed-based `for_each_while(rng, sink)` customization point instead of pull-based iterators.Optimization gives us a glimpse into a world where ranges are no longer constrained by iterators, enabling heterogeneous ranges of multiple types. Heterogeneous ranges allow us to use types like `std::tuple` in range algorithms, do type-based metaprogramming using regular views, and efficiently handle ranges over polymorphic types. This truly takes the power of ranges to the next level!---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Missing_and_Future_Cpp_Range_Concepts.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Jonathan MüllerJonathan is a Software Engineer at think-cell.

We will start with a brief history of "reflection" history. We'll continue with an introduction of utilities from the latest reflection proposal. Then, we delve deeper into practical applications and demonstrate solutions to problems that commonly use reflection and the power it holds. For the last part, we will explore the possibilities within “Reflection Libraries”. This includes both “traditional” libraries which provide functionality, and more “novel” approaches which reshape users’ code. We will look at examples of what such libraries can cover, and demonstrate potential directions the future holds. Last but not least, we will discuss how "Reflection" may impact the way we manage our codebases and the delivery process.Join us as we traverse the meta::[[verse]]!---Slides: slides.com/inballevi/welcome-to-v1-0-of-the-meta-verse-cpp-nowJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Inbal LeviInbal Levi is a Lead Software Engineer at Microsoft with an interest in code readability, compilers, language and software design.

Beyond Sequential Consistency - Leveraging Atomics for Fun & Profit - Christopher Fretz C++Now 2025 CppNow 2025-08-11 | https://www.cppnow.org---Beyond Sequential Consistency - Leveraging Atomics for Fun and Profit - Christopher Fretz - C++Now 2025---In 2011, C++ introduced a formally defined memory model, providing a foundation for portable, multi-threaded code with well-defined correctness guarantees. This was a major milestone, enabling expressive threading primitives and safe concurrency patterns while allowing low-level optimizations for performance.By default, C++ atomics enforce sequential consistency, which ensures intuitive, predictable behavior. However, these strong guarantees often exceed what’s necessary for correctness and come with a performance cost.This talk delves into weaker memory orderings, particularly acquire/release and relaxed semantics, using a ring buffer as a practical example of how they can be used. We’ll also examine how the C++ memory model maps to real hardware, focusing on x86’s native guarantees, and comparing against less coherent platforms like ARM. We'll explore how strategic use of weaker synchronization can unlock significant performance gains without sacrificing correctness.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Beyond_Sequential_Consistency.pptxJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Christopher FretzChris is a senior C++ engineer working at Bloomberg LP on a developer experience team for a large organization within the company's market data pipeline.

This talk is tailored for developers eager to harness the power of C++20 modules in their projects. We will explore the fundamentals of building both shared and static libraries using CMake, the de facto build system for C++. Attendees will gain practical insights into setting up build files and organizing source code with modules. We will dissect real-world open-source module projects, offering a concrete understanding of how modules are being used in the wild. A key focus will be on the "import std" model, demonstrating how to create a module interface for large, existing libraries, facilitating a smoother transition to modular codebases. Significantly, CMake released non-experimental support for C++20 modules in October 2023, marking a pivotal moment for developers. Visual Studio, Clang and GCC all have some level of support for modules. However, the adoption of this feature is still in its early stages, with relatively few projects currently leveraging it. This session will bridge that gap, providing the essential knowledge and hands-on techniques to confidently integrate C++20 modules into your development workflow. By the end of this session, participants will be equipped with the knowledge to effectively use CMake for building projects with C++20 modules, making the most of this cutting-edge feature to enhance their codebases. Whether you're maintaining legacy code or starting a new project, this talk will provide the essential tools and techniques to master C++20 modules.---Slides: github.com/boostcon/cppnow_presentations_2025/blob/main/Presentations/Import_CMake_Mastering_Cpp_Modules.pdfJoin think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Bill HoffmanMr. Hoffman is a founder of Kitware and currently serves as Chairman of the Board, Vice President, and Chief Technical Officer (CTO).

Modern CMake has been around for about a decade now, but in practice CMake use tends to be uneven and overcomplicated. This causes frustration among maintainers and steep learning curves among developers. It also results in overly complicated C++ projects. Even first-class open-source C++ projects often have CMake snarls and snags. Is there a basic CMake approach that just works?In this talk, hear from a CMake veteran about how to keep it simple with CMake. We’ll cover modern CMake principles to keep in mind while maintaining projects built with CMake. We’ll talk about up-to-date CMake basics you’ll find useful – and (some of) the bells and whistles you can skip. To make it easier to keep coming back to these concepts, these recommendations will all be demonstrated with a project you can refer back to. Along the way, we’ll cover some new open-source C++ projects meant to improve our quality of life, while maintaining that “it just works” experience.---Join think-cell as a C++ Developer and work on cutting-edge challenges with a focus on code excellence, innovation, and working alongside an international team of experts — apply now to be part of a team shaping the future of business presentations. think-cell.com/en/career---Bret BrownBret likes making authoring and maintaining C++ codebases simpler and more intuitive by treating projects more like cattle and less like pets.

Modernizing Finite State Machines in C++ - Empower Simplicity & Boost Performance With std::variant CppNow 2024-10-28 | cppnow.org---Modernizing Finite State Machines Implementation in C++ - Empower Simplicity and Boost Performance With std::variant - Amandeep Chawla - C++Now 2024---Finite State Machines (FSMs) are fundamental tools in computer science for modeling behavior in various systems, from software applications to hardware controllers. Traditionally, implementing FSMs in C++ involved using multiple inheritance hierarchies for representing states, events and actions along with heap-allocated objects. However, with the introduction of std::variant in modern C++, there is a compelling opportunity to revolutionize FSM design, offering simplicity, type safety, and performance improvements.In this talk, we explore how leveraging std::variant transforms FSM implementation, allowing for a more intuitive representation of states and transitions. By embracing variant-based FSMs, developers can streamline code, enhance readability, and mitigate common pitfalls associated with traditional FSM designs. Furthermore, we delve into performance considerations and showcase how std::variant facilitates efficient state management, removing need for heap allocation at all.Attendees will gain insights into the principles of FSM design, understand the benefits of adopting std::variant for FSM implementation, and learn practical strategies for incorporating modernized FSMs into their C++ projects. Whether you're a seasoned C++ developer seeking to simplify FSMs or a newcomer exploring advanced language features, this talk offers valuable perspectives on harnessing the power of std::variant to elevate FSM development to new heights.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/Modernizing_Finite_State_Machines_Implementation.pdf ---Amandeep ChawlaAmandeep Chawla is a seasoned software engineer with over 20 years of experience in C++.

The C++ Vector Challenge - Lisa Lippincott - C++Now 2024 CppNow 2024-10-26 | cppnow.org---The C++ Vector Challenge - Lisa Lippincott - C++Now 2024---Many years ago, a conversation with a C++ luminary lead me to focus my attention on a particular question: How can we extend a procedural language like C++ to express the reasoning that underlies our programs in a way that can be statically checked? And how can we make it practical to express the interfaces between the various parts of our programs, so that we may check that the parts fit together properly?In the years since I have made some progress, particularly with the interfaces for functions. But I’ve held onto one remark from that early conversation, taking it as a challenge, as a milepost on the horizon: someday I should write a formal interface for the standard template vector.Twenty years later, vector remains a difficult problem. In this lecture I will describe not only the progress I’ve made, but also the difficulties that remain, and the properties that make vector so troublesome. It will also be my first foray into describing object interfaces.So this talk can be seen from several angles. For some, it will be a deep dive into the way vector works. For others, it will explore the specification of object interfaces. And underlying that, it will examine some streams of thought that came together in C++, and the conflicts between those streams that impede formal specification.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/The_Vector_Challenge.pdf ---Lisa LippincottLisa Lippincott designed the software architectures of Tanium and BigFix, two systems for managing large fleets of computers.

Security in C++ - Hardening Techniques From the Trenches - Louis Dionne - C++Now 2024 CppNow 2024-10-21 | cppnow.org---Security in C++ - Hardening techniques from the trenches - Louis Dionne - C++Now 2024---C++ has gotten a lot of attention lately for being a memory-unsafe language. However, less well-known is the existence of mitigation techniques for certain spatial and temporal memory safety issues. While imperfect, these techniques can help greatly improve the security of existing C++ applications often without requiring any code changes.This talk will go over two concrete mitigation techniques we implemented as extensions in the Clang and libc++ toolchain: Standard Library hardening and typed memory allocation. Standard Library hardening allows catching common cases of undefined behavior such as out-of-bounds memory accesses and turning them into guaranteed traps. Typed memory allocation allows passing compiler-inferred type information to the system allocator, which can then isolate memory allocations based on types so as to make it more difficult to put together a type confusion attack by exploiting a temporal memory safety issue.We will discuss our experience adopting and enabling these mitigation techniques in production on large, performance and security critical code bases. We will also go over some of the evolutionary challenges we met along the way and how we resolved them. Finally, we will propose a path forward to make targeted changes to the C++ Standard that would allow these mitigation techniques to be first class citizens of the Standard.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/Hardening_Techniques_from_the_Trenches.pdf ---Louis DionneI work at Apple where I lead the development of libc++, the Standard Library under the LLVM project and used by the Clang compiler.---C++Now 2025 - 28th April - 2nd MayC++Now is an annual onsite international C++ programming and coding conference held in Aspen, Colarado.

The Most Important API Design Guideline - No, Its Not That One - Jody Hagins - C++Now 2024 CppNow 2024-10-19 | cppnow.org---The Most Important API Design Guideline - No, It's Not That One - Jody Hagins - C++Now 2024---Scott Meyers has famously proclaimed that the most important general design guideline is to make interfaces easy to use correctly and hard to use incorrectly. I don't dispute that claim, for the general case. However, for the specific case of an API, and in particular C++ library code, this guideline must take a back seat to something else.So, what should that something else be? Obviously, since the above paragraph mentions C++ specifically, it must relate to performance in some way. Could it be to make interfaces as efficient as possible? If not, then what in the world could it be?This talk will take a brief survey of general software design guidelines. Then, we will look at some specific examples. For some libraries, like the standard library, the design guidelines are well documented. For others, like many boost components, the design guidelines are part of the documentation. For others, we need to actually look at the API to see if we can determine the design guidelines that were used, if indeed, any guideline was used at all.Finally, I will discuss what I believe to be the most important design guideline, and the implications for how we design and implement software in C++. In support of this claim, I will also present some patterns that can be used to effectively achieve this (and other) design goals.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/The_Most_Important_API_Design_Guideline.pdf ---Jody HaginsJody Hagins started using C++ back in the mid 1980s, with cfront.

Concept Maps using C++23 Library Tech - Indirection to APIs for a Concept - Steve Downey - C++Now 24 CppNow 2024-10-14 | cppnow.org---Concept Maps using C++23 Library Tech - Indirection to APIs for a Concept - Steve Downey - C++Now 2024---C++0x Concepts included a feature called "Concept Maps," which allowed a set of functions, types, and template definitions to be associated with a concept and the map to be specialized for types that meet that concept. This allowed for open extension of a concept. A definition could be provided that allows an algorithm to operate in terms of the API that concept presents, and the map would then define how those operations are implemented for a particular type. This is similar to how typeclasses work in Haskell.The feature was very general, and was lost as part of the Concepts-Lite proposal that was eventually adopted. This loss of a level of indirection means that the APIs for a concept must be implemented by those names for a type, even when those names are not particularly good choices in the natural domain of a type rather than in the domain as a concept. The proliferation of transform functions for a functorial map is such a problem. It is also a problem when adapting types that are closed for extension or do not permit member functions.In this talk, I will demonstrate a technique using inline variable templates that deliver many of the benefits of concept maps -- at the cost of some syntactic noise in the use in algorithms -- and some advanced machinery which allows minimal definitions of a basis set of operations that can be used to implement the rest of the map. In particular, we will discuss using deducing this (P0847) in addition to -- not as a replacement for -- the Curiously Recurring Template Pattern, which allows syntactically checked definitions of the minimal basis set.To make the technique concrete, I will present a simple binary tree data structure that uses tags to classify the nodes. The tags are required to model the monoid concept, which requires that the tag type have a binary operation and an instance that is an identity for that operation. Integers with the identity element 0 and the operation plus form a monoid. Using different operations and identity elements, the tree can represent a data structure that provides sequenced indexed access – like std::vector or std::deque, a priority queue – like std::priority_queue, or searchability – like std::map, without changes to the core data structure. The binary tree operations are modeled after the more complicated fingertree data structure, which shares the flexible characteristics provided by tags with much greater efficiency.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/Concept_Maps_using_Cpp23_Library_Tech.pdf ---Steve DowneySteve Downey has been a programmer for more than 30 years.

They present the programmer with an infinitely detailed view of program execution: the programmer can inspect any piece of program state (memory or registers) for any line of code that executed. And all with surprisingly low runtime and memory overheads. This is especially relevant for C++ which, by design, allows for many kinds of bugs that are impossible in other, safer languages.But how do these seemingly-magically tools really work? This talk dives deep into the implementation details of the three highest profile time travel debuggers: rr, Microsoft's TTD, and Undo.io. All three have some common traits and important differences.

Providing useful and reusable libraries means stepping outside the C++ syntax to consider other kinds of interfaces provided by our C++ projects.This talk goes beyond the C++ syntax to fill in these gaps through an exploration of the other kinds of interfaces and contracts that are implicitly and explicitly provided by C++ projects.During this discussion, contract-based thinking will be applied to the parts of C++ projects that are not C++ source code.

Unit Testing an Expression Template Library in C++20 - Braden Ganetsky - C++Now 2024 CppNow 2024-10-07 | cppnow.org---Unit Testing an Expression Template Library in C++20 - Braden Ganetsky - C++Now 2024---Expression templates are one of the wonders that set C++ apart from all other programming languages. Using just the C++ type system, we can store arbitrary information in a type, giving us a way to calculate anything at compile-time. As years have gone by, we now have new ways of expressing compile-time computation, removing the need for relics of the past like expression templates. However, for some of us, expression templates remain a fascination, bordering on obsession.Regardless of the paradigm, unit testing code at compile-time is no trivial matter. In very rare cases, a compiler's output can vary between compile-time and run-time, given identical source code. Therefore, in order to properly unit test a library meant for compile-time computation, we must run compile-time tests.This talk will use an expression template parser combinator library as a case study to delve into the world of compile-time testing. Triggering a conditional miscompile is easy, but we all know that C++ compiler output can get notoriously unruly upon hitting errors. Therefore, we will explore ways to attain as much readability as possible in our diagnostics and error messages. Throughout the talk, we will contrast the popular unit testing libraries' solutions to compile-time testing, and we will learn which features are left to be desired. We will push the language to its limits to achieve the most user-friendly error messages we can get, while looking back on how far C++ has come in terms of compile-time programming. Ultimately, we will end up where all C++ users eventually stand: wanting more features out of the language. We will end with a roadmap of sorts, showing which future versions of C++ are slated to render our compile-time testing much simpler and more expressive than we can achieve today, and which desired features have yet to commence the standardization pipeline.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/Unit_Testing_an_Expression_Template_Library_in_Cpp20.pdf ---Braden GanetskyBraden Ganetsky graduated from the University of Manitoba with a degree in mechanical engineering, fueled by his passion for mechanical puzzles.

Generic Arity: Definition-Checked Variadics in Carbon - Geoffrey Romer - C++Now 2024 CppNow 2024-10-05 | cppnow.org---Generic Arity: Definition-Checked Variadics in Carbon - Geoffrey Romer - C++Now 2024---In this talk, I will describe an approach to modeling variadic functions in the type system, by treating them as strongly typed functions that are generic over their arity, rather than as templates that are instantiated and then duck-typed. This forms the basis of the current proposed design for variadic functions in Carbon, an experimental C++ successor language.Variadic functions are functions that are generic with respect to the arity (number of parameters), rather than only the types of the parameters. In C++, each instantiation of a generic function must be typechecked separately. However, in Carbon, generic functions can be definition-checked, meaning that the function body is fully type-checked once, using only the type constraints declared in the function signature. To extend Carbon's approach to variadic functions, we have to be able to reason about variadic argument lists as values with types, and solve problems like: - How do we represent types with variadic components? - How do we type-check function calls when we don't yet know which arguments correspond to which parameters? - How can the syntax provide enough type information for definition checking to succeed, without overwhelming the business logic?Carbon also prioritizes build performance, so we need a way to express variadic logic that can avoid the quadratic overhead (or worse) that often arises from C++'s recursion-oriented variadics model. And, as a C++ successor language, we need to do all that without compromising the expressive power of C++ variadics.I will give an overview of how we plan to solve these problems in Carbon, enabling both tools and users to reason about the correctness of variadic code once and for all, rather than one instantiation at a time. You don't need previous familiarity with Carbon; I will introduce the relevant parts of the language as part of my talk.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/Generic_Arity.pdf ---Geoffrey RomerI'm a software engineer at Google, where I work on the Carbon project.

Even if the problem itself is trivial, the cost of resolving it can increase exponentially if it takes days to reproduce or is rarely reproduced. Valgrind, ASan, and LSan are all great tools for detecting memory leaks. However, applying these tools requires restarting the target process. In other words, the issue needs to be tested and reproduced again after the tool is applied.eBPF is an in-kernel VM that empowers users to inject code into the Linux Kernel. Taking advantage of this powerful feature, ALSan can be attached to running processes and detect memory leaks on the fly, allowing the root cause be better detected and reducing the cost of issue reproduction. This tool is built upon the open-source BCC(BPF Compiler Collection) project, which is one of the most famous open-source project in eBPF community. The performance impact is similar to that of llvm-project's LSan.---Slides: github.com/boostcon/cppnow_presentations_2024/blob/main/Presentations/ALSAN.pdf ---Bojun SeoBojun is a software engineer deeply committed to detecting memory leaks. He has been working as a software engineer at LG Electronics. His primary responsibility at LG Electronics is to identify and fix memory leaks on various products, such as fridges, cars, TVs, and so on.Recently, he has started to create tools that utilize the cutting-edge eBPF (extended Berkeley Packet Filter) functionality to solve various problems, including memory leaks. He is a contributor to the open-source BCC (BPF Compiler Collection) project, which is one of the most famous project in eBPF community.He was a presenter at the 8th Korea Linux Kernel Developer Conference in 2023.---C++Now 2025 - 28th April - 2nd MayC++Now is an annual onsite international C++ programming and coding conference held in Aspen, Colarado.
