New video!

Qt as a C++ Framework: History, Present State and Future

by Lars Knoll

From the article:

Qt is one of the largest and most widely used C++ frameworks. It is fully cross-platform, covering all functionality required to develop advanced graphical applications. The talk will go through important parts of Qt's history from it's roots to what it is today. We will have a look into the relation between Qt and C++, some of the design philosophies driving the evolution of Qt. I'll go through the current state of the frameworks, latest releases, ongoing development focus, and give an outlook into the future.

#CPPCON2017. Day 4. Async Rulezzz!

by "No Bugs" Hare

From the article:

During the Day 4 of CPPCON, I had to prepare to my own talk tomorrow; still – I was able to attend all the talks I was interested in.

But before I can start – let’s discuss a thing which I just understood during CPPCON17; it is related to…

Meta: Thoughts on generative C++

by Herb Sutter

From the article:

Two years ago, I started to focus on exploring ways that we might evolve the C++ language itself to make C++ programming both more powerful and simpler. The only way to accomplish both of those goals at the same time is by adding abstractions that let programmers directly express their intent—to elevate comments and documentation to testable code, and elevate coding patterns and idioms into compiler-checkable declarations. The work came up with several potential candidate features where judiciously adding some power to the language could simplify code dramatically, while staying true to C++'s core values of efficient abstraction, closeness to hardware, and the zero-overhead principle.

The first two potential candidate features from that work to be further developed and proposed for ISO C++ are the ＜=＞ unified comparison operator (minor) and what I've provisionally called "metaclasses" as a way to generatively write C++ types (major). This talk is about the latter, and includes design motivation, current progress, and some live online compiler demos using the prototype Clang-based compiler built by Andrew Sutton and hosted at godbolt.org.

C++ as a "Live at Head" Language

by Titus Winters

From the article:

Engineering is programming integrated over time. That is to say, as much as it can be difficult to get your code to build and run correctly, it is manifestly harder to keep it working in the face of changing assumptions and requirements. This is true no matter the scale, from a small program to a shared library. Only two solutions have been shown to be theoretically sound: never change or provide no compatibility guarantees. What if there were a third option? What if we took the question of maintenance out of the realm of theory and moved it to practice? This talk discusses the approach we've used at Google and how that intersects with other languages, package management, API and ABI compatibility, and a host of other software engineering practices. The particulars of C++ as a language and an ecosystem make it well positioned for a different approach: Live at Head.

#CPPCON2017. Day 2. Why Local Allocators are a Good Thing(tm) Performance-Wise, and Why I am Very Cautious about C++17 STL parallelized algos

by "No Bugs" Hare

From the article:

At CPPCON2017 Day 2, two talks were of special interest to me. One was a 2-hour talk about Local Allocators – and another about C++17 STL parallelised algorithms.

CppCon 2017: Learning and Teaching Modern C++--Bjarne Stroustrup

Cppcon 2017 opening keynote by Bjarne Stroustrup is now live.

Learning and Teaching Modern C++

by Bjarne Stroustrup

From the article:

We – attendees at CppCon – are all teachers. Some teach for a living; many occasionally teach a course or give a lecture; essentially all give advice about how to learn C++ or how to use C++. The communities we address are incredibly diverse.

What do we teach, and why? Who do we teach, and how? What is “modern C++”? How do we avoid pushing our own mistakes onto innocent learners?

Teaching C++ implies a view of what C++ is; there is no value-neutral teaching. What teaching tools and support do we need? Consider libraries, compiler support, and tools for learners. This talk asks a lot of questions and offers a few answers. Its aim is to start a discussion, so the Q&A will be relatively long.

Introducing Abseil, a new common libraries project--Titus Winters

A new library is out!

Introducing Abseil, a new common libraries project

by Titus Winters

From the article:

Today we are open sourcing Abseil, a collection of libraries drawn from the most fundamental pieces of Google’s internal codebase. These libraries are the nuts-and-bolts that underpin almost everything that Google runs. Bits and pieces of these APIs are embedded in most of our open source projects, and now we have brought them together into one comprehensive project. Abseil encompasses the most basic building blocks of Google’s codebase: code that is production tested and will be fully maintained for years to come.
