The Future of C++ (KDAB interview)
This episode is slightly different to the normal. Rather than being a pure cpp.chat session, it's a recording of an interview, conducted by KDAB, of a panel of C++ experts, including our own Jon Kalb - but also past cpp.chat guests Ivan Čukić and Jens Weller, as well as Matthias Kalle Dalheimer....
-
The Answer Is, It Depends
In this episode we welcome back Tony and Klaus to talk about the [SOLID](https://en.wikipedia.org/wiki/SOLID) Principles, and how they relate (or not), to C++. Tony is about to give a keynote at C++ Now about his take on the SOLID Principles. Klaus has been giving a talk on applying SOLID to C++...
-
Required to Warn You, Unless It’s Hard
This week we get back on track and chat with Christopher Di Bella from Google about working on the Chrome OS toolchain - including his newly finished concepts implementation. We talk a bit about the practicalities of bringing C++ 20 features to compilers, interoperating GCC and Clang and how to...
-
I'm a Bit Rusty
This week we have a special panel made up of members of the C++ community, joined by members of the Rust community. We have a round table discussion of how the two languages relate, differ - and how entwined their fates may be. We also learn why Rust doesn't have random numbers, but why it's…

Izzy's 'Fine' With Modules
This week we chat with Isabella (Izzy) Muerte about modules, build systems and more. We talk about xyr new job (which, at the time of recording, was with Netlify), and how that still involves working on build systems - but particularly CMake, where xe has found an intriguing special use for…
more -
Chairs Around a Tony Table
This week we chat with Tony Van Eerd about what comes after Post Modern C++, what the single most important principle for good code is, and what Dr. Seuss and Shakespeare have to do with all this. The off-by-one jokes are regular, or at least semi-regular, but what proposals has Tony killed? And...
-
I Really like Sugar
This week we chat with a Conor Hoekstra, about dreaming in algorithms, being a programming language addict and writing beautiful code. We look at what Conor is jealous of in other languages, why his competitive coding entry came dead last, and why he really likes sugar and dopamine. And is it...
-
My Friends Call Me Bool
This week we chat with a vector-of-bool (a.k.a. Colby Pike). We talk about pseudonyms, modules, build systems and his standard layout proposal, Pitchfork. At the last minute we branch into TDD and what makes good design. But what prompts Michael Caisse, in the chat, to respond, 'because we are…
more -
It Doesn’t Get Bored and It Doesn’t Get Tired
This week we chat with a Yuri Minaev, of PVS Studio, about static analysis - and why you shouldn't be skipping on this essential part of software development. Why is using a static analysis tool better than peer review (the clue is in the title)? Should you do both? What is the most common bug?…
more -
The Problem Is, They Expect Answers
This week we chat with a panel of C++ trainers from around the world (but mostly from Germany, for some reason) - Nicolai Josuttis, Jason Turner, Rainer Grimm, Klaus Iglberger and Mateusz Pusz. We talk about how bringing in a good trainer will keep your costs down, whether online training works…
more -
Willing to Steal Good Ideas
This week we chat with Bryce Adelstein Lelbach about how the ISO C++ WG21 committee is evolving - and his roles within it (and beyond) are evolving, too. We also look at the cross-over and interaction with the C standard, and even other languages. Is C really the Latin of programming languages?...
-
We’re Not Going to Allow You to Throw 💩 Anymore
This week we chat with five members of the SG16 Unicode Study Group, Zach Laine, Tom Honermann, Steve Downey, Peter Brett and Corentin Jabot. We talk about their efforts to get all things Unicode into the C++ standard in a tour that takes us from 5000 years ago, through the 80s and 90s up to the...
-
Colour Is Not Black and White
This week we chat with James Berrow about colo(u)r, and how we're doing it all wrong (and not just the spelling). We look at why colour management is complicated, how RGB doesn't exist, and how everybody (well, almost everybody) gets it all wrong. We also look at the graphics proposal, and James'...
-
Ranting Is Optional
This week we chat with JeanHeyd Meneide (A.K.A. ThePhD) about coming full circle on std::embed, as well as whether optional references should rebind or assign-through.

Copperspice Is Your Middle Name?
This week we chat with Ansel Sermersheim and Barbara Geller about Copperspice, Doxypress, csLibGuarded and kitchen utensils. We find out that Barbara and Ansel are not just library people but are actually programmers - and programmers that know how to build abstractions. We chat about why they...
-
Set a Breakpoint in the Past
This week we chat with Greg Law about debugging and going back in time! How do things change when we can wait for something to go wrong, then go back to any point in time and examine the program state, like The Matrix's 'Bullet Time'? How is this even possible, and what challenges need to be...
-
We Almost Always Get the Default Wrong
This week we chat with Vittorio Romeo about the pros and cons of backwards compatibility in C++, and his proposal to get the best of both worlds: Epochs. As well as language compatibility, we also discuss _ABI_ compatibility - why breaking these things is such a problem, but how _not_ breaking…
more -
If You Change It and You Break It, You’ll Know
This week we chat with Clare Macrae about Approval Testing, testing in general, the challenges (and some solutions to) testing legacy code - as well as highly visual environments like Qt GUIs or image processing apps. Working with an existing codebase that doesn't have tests can be scary and time...
-
All the C++30 Features - but Right Now
This week, in a cpp.chat exclusive, we chat with Sean Baxter about Circle - the C++ compiler that he wrote. That’s a C++ compiler. That he wrote. Oh, and it does meta-programming in a way that we’re only dreaming of part of for C++23 or 26! So what can it do, and what is it useful for? Why is Jon...
-
I’m Surprised You Brought up Rotate
In our second live CppCon 2019 episode we chat with Sean Parent about relationships, working with Alexander Stepanov, over-object-orientizing things and, yes, even rotate. Sean tells us stories from his years at Adobe, including how he first came to work with Stepanov (the father of the STL) - a...
-
You Get to Fix It the next Time
The first of our two, live, CppCon 2019 episodes - this time we sit with Andrei Alexandrescu and Herb Sutter to introspect about introspection and take exception to exceptions. We also talk about the 'Engage, Entertain, Educate: Technical Speaking that Works' class that Andrei was involved with,...
-
The Shape of the Value
This week we chat with David Sankel and Michael Park about their Pattern Matching proposal, as well as a language level variant. We look at how some judicious use of syntactic sugar can improve even the ugliest part of the sausage. Pattern Matching (as well as the language version of Variant) are...
-
There's No Secret to Security. The Secret Is ...
This week we chat with Patricia Aas about secure coding practices, using computers to count votes in elections and the two hardest problems in software development. Patricia and Phil have both been at NDC TechTown all week where Patricia gave a keynote, a two-day class, a talk and hosted a…

Can Everyone Stop Saying "Tupple"
This week we chat with Guy Davidson about linear algebra coming to C++, other mathsy stuff, audio, games dev and C++ training evenings. We barely even mention 2D graphics once! Did you know that Guy has written four linear algebra libraries in C++ since 1990? He's in a good position to be…
more -
Hell's Corner: Shared Mutable State
This week we chat with Juan Pedro Bolívar Puente (a.k.a. JuanPe) about immutable data structures, value types and more - and definitely not functional programming! How can data types be valuable if you can't change them? How can copying huge amounts of data be cheap? How can we go beyond...
-
How Often Do People Move Functions?
This week we chat with Pablo Santos, founder and chief engineer of Plastic SCM, and SemanticMerge. Pablo talks to us about how the 'full stack' version control system he created at Plastic SCM differentiates itself in the age of GitHub, how times have moved on for VCS systems (largely driven by...
-
You Do Not Understand Anything as Well as You Think You Do
This week we chat with Ivan Čukić about Functional Programming, despite him not wanting to be known as 'The Functional Programming Guy', TMP and OO, and how he was taught C++ in high school. How does Ivan balance writing books (in fact will he write another book?) and speaking at conferences...
-
The Puns Only Appeared after We Added Co_
After a break of a few weeks we're back with an episode actually recorded on March 12th (when Phil had a cold). We chat with Gor Nishanov about Coroutines, which were just adopted into the draft standard for C++20. We talk about what Coroutines are, why recent talks may have been given the wrong...
-
How Hard Is It to Write a Build Tool?
This week we're joined by Ben Craig as we chat about Modules, as was recently adopted into the C++20 draft standard in the meeting at Kona.

-
The next Call to Random() Must Be 4
We've talked about contracts before, but this week Björn Fahller joins us to give us his thoughts, based on his recent talk at C++ on Sea. This is all pre-Kona - the recent Standards meeting that saw several tweaks to the wording for contracts in the draft standard for C++20. Björn gives us a...
-
If You Took a Cookie You Owe Us a Lightning Talk

-
I Don't Think I Could Code My Way out of a Paper Bag
This week we chat with Frances Buontempo and Andy Balaam about Machine Learning, Artificial Intelligence and Genetic Algorithms. We learn how ML is mostly just 'multiplying and adding up' with a bit of 'randomly trying stuff out' but that you might need a kill switch - except when you don't. We...
-
We Made It Even Worse
This week we're joined, once again (yet for the first time) by Nicolai Josuttis, and we talk about how much of a C++ expert you need to be to write 'Hello, World' and initialize objects. We also discover how strongly Jon feels about initializer_list constructor syntax - and what Nico thinks about...

I Could Get Compile-time Threads
After a bit of a break, we're back - and with non-other than Bjarne Stroustrup! We chat about the state of C++, from the hardcore of the committee to the whole community and also look at where we think it should go and maybe where it is going.
-
Control over Space and Time
After a bit of a break in the lead up to CppCon, in this interview we chat with Herb Sutter - in front of a live audience at CppCon itself. We chat a bit about the conference, how it has been 'the best ever' (yet again), but also how it is the last one in that location (CppCon moves to Aurora…

It Works but It's Undefined Behaviour
This week we welcome back Howard Hinnant and Arthur O'Dwyer to discuss Arthur's paper, P1144, 'Trivially Relocatable'. We talk about what it is, what problems it solves, older papers covering the same ground, and even another in-flight paper (P1029) that it overlaps with. As one of the original...
-
Who, Here, Writes Unit Tests?
This week we manage to align with the calendars of Kevlin Henney and Martin Hořeňovský to talk about testing and beyond - with a particular focus on Catch2 - past, present and future. We discuss how some of Kevlin's ideas influenced Catch originally, and how Martin later joined as a co-maintainer...
-
Hotfix Our Way to Security
The week we chat with Eva Conti, Troy Hunt and Matthew Butler on the topic of secure coding (so that's what safe coding is!). Eva and Matt are reformed hackers themselves and share some of their unique insights from the dark side, and how that can inform all of us in our coding practices -...
-
A Whole Arsenal of Foot Guns
This week we welcome Anastasia Kazakova and Dmitry Kozhevnikov to talk about the recent release of CLion 2018.2, as well as the upcoming release of ReSharper C++. We particularly talk about the new clangd based language engine that CLion now uses alongside it's own, as well as the next step…
