🔍 Check the full session lineup here: https://schedule.cppnow.org

How Early Access Works:

EA videos will be released shortly after the conference concludes.
Public YouTube releases begin at least 30 days later, at a rate of 3 videos per week.
Videos will be published in schedule order—so talks later in the event may remain exclusive for 3–4 months.
Once videos are public, they’ll also be unlocked in the EA portal for everyone to browse and search.

A Long-Term Resource for the C++ Community:

The EA portal is more than early access—it’s a growing video archive and search system for C++Now and other conferences like ACCU and CppCon, developed by Digital Medium Ltd.

Eventually, this system will provide a free, unified interface for browsing technical talks across multiple C++ conferences—open to all developers.

By attending C++Now 2026, you’re directly supporting the development of this free, public resource.

C++Now Keynote: Generic Programming Considered Harmful? – Jeff Garland

https://schedule.cppnow.org/session/2025/generic-programming-considered-harmful/

In his seminal 1968 paper “Go To Statement Considered Harmful,” Edsger Dijkstra argued that unstructured control flow leads to tangled, hard-to-maintain code. The critique reshaped programming, ushering in an era of structured design that has influenced software development for over 50 years.

Similarly, generic programming is a cornerstone of modern C++, enabling powerful abstractions and highly reusable code. However, it comes at a cost: increased compilation times, cryptic error messages, and cognitive overhead that challenges even expert developers. Has generic programming delivered on its promises, or is it actively undermining progress?

To frame this question, we’ll take an epic journey spanning 15 billion miles, down to 5 nanometers, and across four decades of software development and computing machine evolution. Along the way, we’ll explore how the abstractions we use to write programs have evolved — highlighting some of the successes and the failures. Ultimately we’ll come back back to where generic programming fits into the picture and it’s contributions.

This session will challenge your perspectives of software development and leave you with a lot to reflect on.

Jeff Garland has worked on many large-scale, distributed software projects over the past 30+ years. The systems span many different domains including telephone switching, industrial process control, satellite ground control, ip-based communications, and financial systems. He has written C++ networked code for several large systems including the development high performance network servers and data distribution frameworks.Mr. Garland’s interest in Boost started in 2000 as a user. Since then he has developed Boost.date_time, become a moderator, served as a review manager for several libraries (including asio and serialization), administered the Boost wiki, and served as a mentor for Google Summer of Code. Mr. Garland holds a Master’s degree in Computer Science from Arizona State University and a Bachelor of Science in Systems Engineering from the University of Arizona.

C++Now Keynote: Balancing the Books – Lisa Lippincott

https://schedule.cppnow.org/session/2025/balancing-the-books/

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.

She’s currently assistant chair of the numerics study group of the C++ standardization committee. In her spare time, she studies mathematical logic, and wants to make computer-checked proofs of correctness a routine part of programming.
