CppCast Episode 22: Bounded Integers with David Stone

by Rob Irving and Jason Turner

About the interviewee:

David Stone has spoken at C++Now and Meeting C++. He is the author of the bounded::integer library and has a special interest in compile-time code generation and error checking, as well as machine learning. He owns DoubleWise C++ Consulting, providing on-site training with an emphasis on performance and correctness. He also works at Markit integrating real-time financial data. He once wrote an optimizing compiler that solved the halting problem, and is just waiting for it to finish compiling his program.

 

The Dos and Don'ts of Multithreading -- Hubert Matthews

Hubert Matthews talked at the this year's ACCU conference in Bristol with lot's of examples and detailed insight about:

The Dos and Don'ts of Multithreading

by Hubert Matthews

From the conference's schedule:

Multithreading is a popular subject and we've all been led to believe that we need to write threaded programs as single-threaded performance hits a ceiling. However, multithreading is no panacea and may cause more problems than it solves. This talk, suitable for programmers of any level and language, seeks to describe some of these problems and also how to avoid them through appropriate design choices.

Large-Scale Scientific C++ For Casual Coders: Why You (Should) Care -- Axel Naumann

Axel Naumann talked in his this year's keynote at the ACCU conference in Bristol about

Large-Scale Scientific C++ For Casual Coders: Why You (Should) Care

by Axel Naumann

From the ACCU's schedule:

This keynote will introduce the use of C++ for storing and analyzing petabytes of C++ objects at CERN, and more generally in High Energy Physics. Many hundreds of developers, including physicists with limited software skills, have contributed to a code base of > 50 million lines of code that has a lifetime of more than 40 years. Axel will talk about the approach taken in order to provide robust and efficient code, including how novices 'conquer' giant interface worlds. He will present a few of the 'tasty' projects that have proven to be useful for people who don't smash particles on a daily basis, for instance their C++ interpreter and a massively scalable web-based file system.

by Rob Irving and Jason Turner

About the interviewee:

James McNellis is a senior engineer on the Visual C++ team at Microsoft, where he works on C++ libraries.  He’s spent the past three years working on a major redesign and refactoring of the Visual C++ C Runtime, which culminated in the release of the Universal CRT with Windows 10 and  Visual Studio 2015.  He occasionally speaks at C++ conferences and was at one time a prolific C++ contributor on Stack Overflow.

CppCon 2014 Lightning Talks--Introduction to Undodb--Julian Smith

By Adrien Hamelin | Aug 5, 2015 08:00 AM | Tags: advanced

Have you registered for CppCon 2015 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2014 for you to enjoy. Here is today’s feature:

Introduction to Undodb

by Julian Smith

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

UndoDB's performance and low memory consumption allows you to step your application backward, as well as forward, faster than any other commercial or open-source reversible debugger. By stepping back in your program, setting a watchpoint or replaying non-deterministic bugs, you can get straight to the root cause of the bugs upsetting your customers, decreasing your productivity and slowing your software releases.

Practical Type Erasure

by Cheinan Marks

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Type erasure looks like a neat concept, but what are its real life uses? This talk will briefly show the inner workings of type erasure, and demonstrate a real working implementation of a configuration system from public domain production code. Uses and pitfalls of type erasure will also be covered.

Polymorphism with Unions

by Jason Lucas

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Using tagged unions to create families of polymorphic types that are more flexible and more easily maintained than those formed with inheritance alone. We demonstrate the design pattern and implementation techniques of sum types with examples from a compiler development project. We also examine the technique's impact on project management and engineering and on algorithm design, including the role of type switches, value type semantics, and multiple dispatch polymorphism.
