CppCon is recuiting volunteers.
Call for Volunteers
for CppCon 2016
From the call:
We need people to help assemble registration packets and badges, register attendees, assist speakers with Audio/Video, and in general be on hand to make things run smoothly. In exchange, we’ll see to it that you’ll spend at least half of your time in sessions.

Interesting interview:
How Bloomberg is Advancing C++ at Scale
by John Lakos
From the article:
John Lakos manages the Bloomberg Development Environment group, which offers a set of C++ software libraries, development tools, and methodology to well over a thousand Bloomberg developers. He is an authority on large-scale C++ software infrastructure, receiving recent acclaim for two publications by Pearson Education on methodology for industrial software development [Part 1, Part 2]. BDE and its libraries are open source and can be found on GitHub. In this conversation, Lakos discusses the importance of instilling process and discipline in all software development projects...

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:
Rcpp: Seamless R and C++ Integration
by Matt P. Dziubinski
Summary of the talk:
R is an open-source statistical language designed with a focus on data analysis. While its historical roots are in statistical applications, it is currently experiencing a rapid growth in popularity in all fields where data matters: from data science, through bioinformatics and finance, to machine learning. Key strengths contributing to this growth include its rich libraries ecosystem (over 6 thousands packages at the moment of writing) – often authored by the leading researchers in the field, providing early access to the latest techniques; beautiful, high-quality visualizations – supporting seamless exploratory data analysis and producing stunning presentations; all of this available in an interactive environment resulting in high productivity through fast iteration times.
At the same time, there are no free lunches in programming: the dynamic, interactive nature of R does have its costs, including a significant impact on run-time performance. In an era of growing data sizes and increasingly realistic models this concern is only becoming more important.
In this talk we provide an introduction to Rcpp – a library allowing smooth integration of R with C++, combining the productivity benefits of R for data science together with the performance of C++. First released in 2005, today it’s the most popular language extension for R -- used by over 400 packages. We'll also discuss challenges (as well as possible solutions) involved in integrating modern C++ code, and demonstrate the usage of popular C++ libraries in practice. We’ll conclude the talk with the RInside package allowing to embed R in C++.

C++ on the Web: Ponies for developers without pwn’ing users
by JF Bastien
Summary of the talk:
Is it possible to write apps in C++ that run in the browser with native code speed? Yes. Can you do this without the security problems associated with running native code downloaded from the net? Yes and yes. Come to this session to learn how.
We'll showcase some resource-intensive applications that have been compiled to run in the browser. These applications run as fast as native code with access to cornerstone native programming APIs—modern C++ STL, OpenGL, files and processes with full access to C++’s concurrency and parallelism—all in an architecture- and OS-agnostic packaging. Then, we'll describe how we deliver native code on the web securely, so developers get their C++ ponies and users don’t get pwn’d. We’ll also touch on the fuzzing, code randomization, and sandboxing that keep the billions of web users safe.

Lessons in Sustainability: How to Maintain a C++ Codebase for Decades
by Titus Winters
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.

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...

Reflection Techniques in C++
by Paul Fultz II
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.

Writing Great Libraries: 89 Easy Steps
by Zach Laine
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.
