By Adrien Hamelin | Aug 12, 2016 02:06 PM | Tags: intermediate efficiency community

Have you registered for CppCon 2016 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 2015 for you to enjoy. Here is today’s feature:

Lessons in Sustainability: How to Maintain a C++ Codebase for Decades

by Titus Winters

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Google maintains (we believe) the largest monolithic C++ codebase in the world with over 100M lines of C++ code. Early commits to this repository date back to the late 1990s. About 4000 engineers submit at least one change in C++ every week. We’ve learned a few things about what it takes to maintain a codebase at this scale.

In this talk I’ll present some of the lessons we’ve learned over the years with respect to policies, technology, education, design, and maintenance of a long-lived monolithic codebase.

Cppcheck-1.75 has been released--Daniel Marjamäki

A new version is here!

Cppcheck-1.75 has been released

by Daniel Marjamäki

From the article:

General changes:

  • Replaced internal preprocessor by the brand-new preprocessor 'simplecpp'
  • Improved Windows installer: Install a copy of the license instead of asking to accept it
  • The Windows x64 binaries are now compiled with profile guided optimization, resulting in a speedup of 11%
  • Improved manual, especially the chapter about Libraries
  • Improved CWE mapping
  • --append is deprecated and will be removed in 1.80...

Some Big-Os are Bigger Than Others
Big-O notation is often used to compare algorithms. Sergey Ignatchenko reminds us that asymptotic limits might not be generally applicable. by Sergey Ignatchenko

Kill the Clones
Problems in code can hide in surprising places. Adam Tornhill demonstrates how to detect software clones and uncover hidden dependencies. by Adam Tornhill

Is testing propositions more important than having examples as exemplars? Russel Winder considers this hypothesis. by Russel Winder

CppCon 2015 Reflection Techniques in C++--Paul Fultz II

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2015 for you to enjoy. Here is today’s feature:

Reflection Techniques in C++

by Paul Fultz II

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Reflection is a very powerful and useful feature used in many languages to achieve things like serialization, object-relationship mapping, and general data-driven development. C++ doesn't support reflection natively in the language yet. There are proposals to add compile-time reflection to the language, but C++ has survived all this time without direct support for reflection.

This talk will discuss the various techniques the can be used to achieve reflection including boost fusion, the visitor patter, and do-it-yourself with some macros and metaprogramming. This talk will discuss how these techniques can be used to implement serialization or object-relational mapping.

CppCon 2015 Writing Great Libraries: 89 Easy Steps--Zach Laine

Writing Great Libraries: 89 Easy Steps

by Zach Laine

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Writing code that does what you want it to do, correctly and efficiently, is hard. Doing so when you don't even know yet what you want the code to do yet is quite a bit harder. Yet this is the job of a library writer -- the users of a library may have a very different use case from that of the original author.

How do library writers develop correct and efficient APIs that are also:

- easy to use correctly - hard to use incorrectly - highly reusable - gracefully interoperable with other code

This talk gives lots of practical advice and techniques for accomplishing those goals and more.

The monthly overview on upcoming C++ User Group meetings on Meeting C++:

C++ User Group Meetings in August

by Jens Weller

From the article:

The monthly overview on the upcoming C++ User Group meetings. As there is again a group meeting at the first, I have to publish this today, so that there will still be some groups not in the listing, as they are publishing their meetings in the coming days. Still, already 26 groups will meet in August!

There are 3 new C++ User Groups: Copenhagen, Singapore, and Gdansk.

CppCon 2015 Test Driven C++ with Catch--Phil Nash

Test Driven C++ with Catch

by Phil Nash

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

C++ has been notorious for being a second class citizen when it comes to test frameworks. There are plenty of them but they tend to be fiddly to set-up and ceremonious to use. Many of them attempt to follow the xUnit template without respect for the language environment they are written for. Catch is an attempt to cut through all of that. It is simple to get and simple to use - being distributed in a single header file - yet is powerful and flexible. Catch includes a number of innovations that make testing in C++ more natural - and fun - than ever before. This presentation introduces you to the unique approach that Catch brings to unit and integration testing - and how to use Catch to drive your design with TDD or BDD.

C++/Graphics Workshop--Stephanie Hurlburt

By Adrien Hamelin | Jul 27, 2016 01:13 PM | Tags: performance community

Are you interested?

C++/Graphics Workshop

by Stephanie Hurlburt

Description of the event:

Ever been curious about C++ and graphics programming, but not sure where to start?
Maybe you are an artist who'd like to build your own tools. Maybe you're a game developer wishing your games would run faster, or have even better graphics effects. Regardless, knowledge of the way graphics work at a low level is an empowering skill.
We'll be covering real-time graphics with C++/OpenGL as well as raytracing. It'll be aimed at beginners, but everyone is welcome.
This'll be an intimate workshop, meant for around 20 people. We'll give a talk and then walk you through some hands-on examples. Be sure to bring a laptop if you can!

Cross-Platform Mobile App Development with Visual C++

by Ankit Asthana & Marc Gregoire

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Visual C++ 2015 supports the development of apps for the Windows platform as well as for Android and iOS. A single code base, possibly with a thin platform-specific UI layer, can be compiled to run on Windows, Android, and iOS. The resulting binary can be published to a device and debugged, all from within Visual C++ 2015. This presentation introduces you to such cross-platform mobile app development, including debugging and emulation, and includes a number of demos.
