Most widely-used programming languages have at least one regular
conference dedicated to discussing it. Heck, even Lisp has
one. It’s a place to talk about the latest developments of the
language, recent and upcoming standards, and so on. However, C is a
notable exception. Despite its role as the foundation of the
entire software ecosystem, there aren’t any regular conferences about
C. I have a couple of theories about why.
First, C is so fundamental and ubiquitous that a conference about C
would be too general. There are so many different uses ranging across
embedded development, operating system kernels, systems programming,
application development, and, most recently, web development
(WebAssembly). It’s just not a cohesive enough topic. Any conference
that might be about C is instead focused on some particular subset of
its application. It’s not a C conference, it’s a database conference,
or an embedded conference, or a Linux conference, or a BSD conference,
Second, C has a tendency to be conservative, changing and growing very
slowly. This is a feature, and one that is often undervalued by
developers. (In fact, I’d personally like to see a future revision
that makes the C language specification smaller and simpler,
rather than accumulate more features.) The last major revision to C
happened in 1999 (C99). There was a minor revision in 2011 (C11), and
an even smaller revision in 2018 (C17). If there was a C conference,
recent changes to the language wouldn’t be a very fruitful topic.
However, the tooling has advanced significantly in recent years,
especially with the advent of LLVM and Clang. This is largely driven
by the C++ community, and C has significantly benefited as a side
effect due to its overlap. Those are topics worthy of conferences, but
these are really C++ conferences.
The closest thing we have to a C conference every year is CppCon. A
lot of CppCon isn’t really just about C++, and the subjects of many
of the talks are easily applied to C, since C++ builds so much upon C.
In a sense, a subset of CppCon could be considered a C conference.
That’s what I’m looking for when I watch the CppCon presentations each
year on YouTube.
Starting last year, I began a list of all the talks that I thought
would be useful to C programmers. Some are entirely relevant to C,
others just have significant portions that are relevant to C. When
someone asks about where they can find a C conference, I send them my

Here’s the list for CppCon 2017. These are roughly ordered from
highest to lowest recommendation:
The final CppCon 2018 videos were uploaded this week, so my 2018
listing can be complete:
There were three talks strictly about C++ that I thought were
interesting from a language design perspective. So I think they’re
worth recommending, too. (In fact, they’re a sort of ammo against
using C++ due to its insane complexity.)
Finally, here are a few more good presentations from other C++
conferences which you can just pretend are about C:
