As the Meeting C++ 2025 call for talks closes next week, I've been thinking about what are you thinking about in regards of C++?

Earlier this week I've asked on Linkedin this question, What C++ topics are interesting to you or your team right now?, plus my self reaching out to various team leads to have discussions on this. With this I'm also trying to give folks an idea what is interesting to the community, though I'd like to stress that all this is under a heavy selection bias. Which means, that if your talk or talk idea is not listed, you still should submit it.

What LinkedIn thinks

Lets take a quick look at the answers from LinkedIn. The first reply I've got was about networking, and inparticular http servers and various server side features such as thread safety, non blocking and event based code. Each of these could be a talk, or you could give an overview. I'm not sure about the Networking TS, as its not going to make it into C++26, talks on libraries in general are also always interesting. And lock free has also been mentioned in other discussions.

Chris Ryan is interested in the purely hardcore language technical talks, and I agree that you should follow a long, and talks about C++20/23/26 with their new C++ features and learnings are a current staple in the community. Reflection has been a popular topic through out the year, and its one of the hot topics to talk about in the future for sure.

There is also a mention of robotics and image recognition, which similar like servers is an application field of C++. That this is also an important category where we often lack talks: the application and specifics of C++ in a certain field.

What I think

While it was a few years ago, I've heard during lunch/dinner/hallway talks some times from folks that they'd like to see more about the application side of things then purely feature based talks. Something that might still hold true for todays conferences. Though speaking about actual work is a bit more complicated for folks then speaking about new features. And learning new things is what motivates a lot of speakers, learning something and writing down notes/slides is a great way to start working on a talk. And when you talk about applying C++ and generalize your examples from your own work, one ends up with processes, libraries and features.

One thing I'm wondering about is, which talks were not submitted? I'd like to see more library authors speak about their libraries or experiences with C++. Tina Ulbrich gave a great lightning talk about what you could talk about at Speaking about C++ in 2022. This years Speaking about C++ will feature again lightning talks from speakers, its next week.

And for a long time fields like game dev, robotics, finance and large libraries like Qt, boost, ROS have been under represented at C++ conferences, due to lack of submissions. But you'd be welcome to submit to Meeting C++ 2025.

Shortly after the call for talks ends, the voting on the submitted talks begins. The voting result will help with knowing which talks are interesting to the community.
