Beyond the Type System -- Lucian Radu Teodorescu

By Lucian Radu Teodorescu | Jul 9, 2018 01:31 PM | Tags: None

Ever wondered how the compiler generates code for your types?

Beyond the Type System

by Lucian Radu Teodorescu

From the article:

Often when we consider a type system we think about a complex formalism to denote the semantics of a language. Languages typically add features by increasing the complexity of the type system.

But there is also another perspective on the type system: how does the generated code look like? what is the ABI for the code that uses different features of the type system? We’ll try to explore this perspective in this blog post.

Everything about unity builds -- Viktor Kirilov

A unity build can cut down build times dramatically and is HIGHLY underrated and easily dismissed by many senior software engineers.

Everything about unity builds

by Viktor Kirilov

From the article:

In this post we will go over what it is, all its pros and cons, and why a “dirty hack” might be worth it if it speeds up your builds by at least a factor of 2 or perhaps even in the double-digits.

CppCon 2017: Coroutines: what can't they do?--Toby Allsopp

By Adrien Hamelin | Jul 9, 2018 01:26 PM | Tags: performance community

Have you registered for CppCon 2018 in September? Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2017 for you to enjoy. Here is today’s feature:

Coroutines: what can't they do?

by Toby Allsopp

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Coroutines are coming. They're coming for your asynchronous operations. They're coming for your lazy generators. This much we know. But once they're here, will they be satisfied with these offerings? They will not. They will require feeding, lest they devour our very souls. We present some fun ways to keep their incessant hunger at bay. I, for one, welcome our new coroutine overlords.

The Coroutines Technical Specification is an experimental extension to the C++ language that allows functions to be suspended and resumed, with the primary aim of simplifying code that invokes asynchronous operations. We present a short introduction to Coroutines followed by some possibly non-obvious ways they can help to simplify your code.

Have you ever wanted to elegantly compose operations that might fail? Coroutines can help. Have you ever wished for a zero-overhead type-erased function wrapper? Coroutines can help. We show you how and more.

Functions in std--Andrzej KrzemieĊ„ski

The Standard reserves the right to change the signatures and overloads of the existing Standard Library functions in what is considered a backward compatible way:

Names of functions from the Standard Library used as pointers/references to functions can cause breakage in your code...

CppCon keynote: Patterns and Techniques Used in the Houdini 3D Graphics Application (Mark Elendt)

headshot1-200x300.jpgNote: Three days left to register for CppCon 2018 at the Early Bird discounted rate.

In 2018, the ISO C++ committee and C++11 were thanked on camera from the Oscars stage. The shout out was by this Academy Award winner, who will be keynoting CppCon this September:

CppCon 2018 Plenary: Patterns and Techniques Used in the Houdini 3D Graphics Application (Mark Elendt)

From the announcement:

Not only has Houdini been used in all of the Visual Effects Academy Award winning films of the past 10 years, but it has also been used for television shows like Game of Thrones and Stranger Things as well as content creation for many AAA video games, and even for scientific visualization.

Houdini artists are tasked with creating amazing, never before seen visual effects. They constantly push both performance and scale in the software. Since the early 1990’s Houdini’s C++ architecture has provided a flexible platform that has enabled artists from around the world to create their vision.

Mark will discuss some of the patterns and approaches that have been used in Houdini to meet the demands of production, from the early days of dealing with c-front to embracing modern features provided by modern C++.

If you’re not sure what CppCon is like, here are sample attendee quotes from a previous CppCon that came up randomly on the CppCon site this morning:

“The 'star' speakers were fantastic as always ... [they] always deliver, and the fact that you can just walk up and talk to them all week is an amazing experience.” “A great way to learn about where the language is going in the future, and to meet the people who make that happen.”

The CppCon Early Bird discounted ticket rate is available for the rest of this week. Register here for CppCon 2018, Sep 23-29!
