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.

A generic context menu class for Qt

An unplanned 5th entry in my series on writing applications in C++ using Qt and boost:

A generic context menu class for Qt

by Jens Weller

From the article:

I didn't plan to write a second post on menus. But a reply on twitter caused me to over think my code I presented yesterday. Its not an very important part, so that I moved on once it did run. So, the simple question, why I would not connect the menus to a slot instead of using a switch was a good one. It would restructure the code, and slots are also callable from the outside world, while the switch buries the code inside a method...

Episode 21 of CppCast the only podcast by C++ developers for C++ developers. In this episode Rob and Jason are joined by James McNellis to discuss new features for C++ developers in Visual Studio 2015 and changes made to the C runtime.

CppCast Episode 21: VS2015 and the Universal CRT with James McNellis

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.

Menus and Widgets in Qt

The fourth part of my series about developing applications with C++ using Qt and boost:

Menus and Widgets in Qt

by Jens Weller

From the article:

Lets start with how Qt sees and handles menus. You can easily create a window menu in the RAD Editor of QtCreator, and then add a slot for its triggered() signal. But for a context menu...

cppcon-046.PNGFrom the cppcon.org announcement:

2015 Program Additions

Most of this fall’s program is already online, but we are still working on it. Today we are announcing three new sessions and a panel.

Herb Sutter will be presenting “Writing Good C++14 By Default.” Herb’s session will build on Bjarne Stroustrup’s keynote of the previous day on “Writing Good C++14.”

Chandler Carruth, C++ Language and Compiler Lead at Google, will be presenting “Tuning C++: Benchmarks, and Compilers, and CPUs! Oh My!”

Sumant Tambe will be presenting “Reactive Stream Processing in Industrial IoT using DDS and Rx.cpp,” which includes a live demo of a distributed complex event processing system for Internet of Things.

Our Monday evening panel will be “Grill the Committee,” featuring the opportunity for audience members to question members of the ISO C++ committee. We’ve not yet identified the panel members, but last year’s panel featured a dozen committee members and we’ll have a similar panel this year.

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.
