The Curse of Backwards Compatibility

We're back! Again! And so is Dave Abrahams, after a long period outside the C++ community. So we thought we should hear about what he's been up to and what he's doing now. We end up getting some fascinating insights into the design and evolution of the Swift programming language,which Dave joined the team behind quite early on. While Swift draws inspiration from many languages, the core of the team behind it - including Dave - were C++ experts - but experts who wanted to take from the best, yet learn from the mistakes, of the past.

The Future of C++ (KDAB interview)

In this episode we welcome back Tony and Klaus to talk about the 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++ and even Phil has recently given a talk on a similar topic.Perhaps somebody should have mentioned this to Tony before! Along the way we get plenty of SOLID advice, discover what the single responsibility is that Tony's objects have, what COLID is,who is going to argue against Liskov, and who is just there for the jokes.

I Really like Sugar

Each fortnight, or thereabouts, we chat with guests from the C++ community about what they're doing, what interests them, and what's going on in the world of C++

I gave this show a shot after hearing about it on some other podcasts. I’ve listened to a handful of episodes and I have to say this show is a no go for me.

The audio quality leaves a lot to be desired but that is only a minor point. Most of my issues comes from the presenters. One of them just constantly talks over everyone else on the show. Guests, his co-host, it doesn’t matter. Personally I’m not listening to interview type podcasts to listen to one of the hosts rant over top of everyone else for most of every episode. When I listen to these types of shows I want to hear mostly from the guests being interviewed and not whatever soap box one of the hosts feels like getting on for that week. 

If you are interested in C++ podcasts CppCast is a much better show. Better presenter style, better interviews, and much less rants.

Better C++ Content Elsewhere

I like the topic but the audio quality has to be one of the worst among podcasts I listen to.

Lots of white noises

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 impression (as they focused on a library writer's perspective,) what is going into the standard (the core language features) and what is not (library support, performance guaranteed by construction) and why.

My Special Technique for Debugging Meta-programming Code

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 them is increasingly becoming a problem. We also, finally, get an answer to the age of question of, "how many programmers does it take to change a lightbulb?"Links:Vittorio's CppCon talk on epochsp1881 - The Epochs Proposal- Epochs: a backward-compatible language evolution mechanismp1863 - ABI Break- Titus Winters' paper on the ABI compatibility issueSPECS- A Modest Proposal: C++ Resyntaxed

We Almost Always Get the Default Wrong

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.

Who, Here, Writes Unit Tests?

This week our main topic is Simplicity and we're joined by Kate Gregory, who will be keynoting CppCon on the subject, and Jonathan Boccara, whose blog is often focused on pursuing simplicity, too.  We cover how to deal with complexity in legacy code, e.g. a report function containing thousands of lines of switch statement (and a 27 step process to add a new report), what simple code looks like to begin with, techniques that help - including functional programming and TDD, and some of the limitations of all these approaches.

We Made It Even Worse

This week we chat with Timur Doumler and Brian Heim about the challenges peculiar to audio development, and find that most are shared with other domains - especially those that consider themselves low-latency and/ or real-time.  Timur has, in the past, worked on audio software at ROLI and Native Instruments, and has been a maintainer of the JUCE audio library - but now works on CLion at JetBrains. Brian is a maintainer of SuperCollider, a platform for audio synthesis and algorithmic composition.Links:ROLIJUCEADCC++ on Sea - speakers call just closingSuperCollider

I Don't Think I Could Code My Way out of a Paper Bag

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 2020s! We look at every known language, including a few dead ones - and some that are purely fictional. Do you know the difference between a code unit and code point? A glyph and a grapheme cluster? String a Text? And what's wrong with Locales anyway?

We’re Not Going to Allow You to Throw 💩 Anymore

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 struggling to wrap his head around what Sean has achieved and can it really turn Twitter into code? If you want to follow along screen shared segment, I've tried to embed screenshots in the podcast mp3 - or you can go to this point in the YouTube recording. And finally, contrary to what Phil says during the show, there were not 130 lightning talks at CppCon.

All the C++30 Features - but Right Now

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,just north of Denver, Colorado, next year). We then dig into Herb's Static(aly-typed, deterministic) Exceptions proposal - what it really means for everyone in the community - and how it fits into Herb's master plan of simplying the language, while doubling down on what C++ is strongest at: zero-cost abstractions, primarily through static-by-default approaches.Links:p0709r2The Design and Evolution of C++Herb Sutter 'Thoughts on a more powerful and simpler C++ (5 of N)'Brand &amp; Nash 'What Could Possibly Go Wrong?: A Tale of Expectations and Exceptions'

Control over Space and Time

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. We talk about how modules interact with build systems, what the deal with macros is, and the new study group set up to advise tools vendors on best practices for supporting modules in an optimal way. We also talk about Ben's ongoing work on moving the Free Standing mode of the standard forwards - and what that really means. To find out what the beneficial crisis is, and why John Lakos might be angry, listen to this episode.

Sean tells us stories from his years at Adobe, including how he first came to work with Stepanov (the father of the STL) - a well as some spectacularly bad responses to interview problems.Links:Sean's CppCon 2019 keynote- Better Code: Relationships

I’m Surprised You Brought up Rotate

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 consuming. But getting it under test is challenging, too.Clare explains how Approval Testing helps here, and how it all works. We also talk about how she has quickly become a sought after speaker, with some tips for first time speakers,and some more general ideas from Agile and Continuous Delivery circles.Links:C++ Approval TestingApproval Tests in generalClare's Approval Testing talk at C++ on SeaClare's Meeting C++ talk: 'Quickly Testing Qt Desktop Applications'- video not yet available at time of writingClare's Approval Testing talk at CppCon- An evolution of the C++ on Sea talkApproval Tests example code- for Reddit questionClare’s new consulting venture

If You Change It and You Break It, You’ll Know

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, again, at CppCon 2019. But Andrei describes himself as a "free radical" and "too much plutonium" and claims he needs Herb as "a bit of graphite" to keep him in check. Listen to find out what the debate is about!Links:Herb's CppCon 2019 keynote- De-fragmenting C++: Making Exceptions and RTTI More Affordable and UsableAndrei's CppCon 2019 keynote- Speed Is Found In The Minds of People

Copperspice Is Your Middle Name?

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 involved with the standardisation effort. But how do you bring something that Fortran excels at to modern standard C++ without it just being the C++ification of Fortran?

Can Everyone Stop Saying "Tupple"

More proposals! This time the main topic is p0847r1, "Deducing this", authored by our guests, Gašper and Ben, along with Barry Revzin and Sy Brand. This proposal is a simple idea, that works by allowing you to make explicit something that has always been implicit in the language. Yet the consequences are many and far reaching - solving many little problems - and simplifying others. Gašper also mentions another proposal of his, p1099r0, "Using Enum", which is another simple language change for added consistency, extra convenience and less verbosity - but otherwise narrower in scope.Links:'Deducing This' proposal (p087r1)'Using Enum' proposal (p1099r0)CppCon (conference - tickets on sale)Meeting C++ (Call for Speakers)Pacific++ (Call for Speakers)C++ on Sea (Call for Speakers)
