CppCon 2016: A modern database interface for C++--Erik Smith

By Adrien Hamelin | Aug 14, 2017 02:44 PM | Tags: community

Have you registered for CppCon 2017 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 2016 for you to enjoy. Here is today’s feature:

A modern database interface for C++

by Erik Smith

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

C++ has historically had many options for database connectivity but has lacked a standard interface that other languages, such as Java, have had for a long time. This talk will present a standards grade interface along with experience with a reference implementation that includes support for at least 6 databases. A key aspect of the design is to show how modern C++ features can be used to achieve a high degree of both efficiency and ease-of-use. Specific features to be covered will include type conversion, connection pooling, I/O binding for scalars and arrays, row sets, direct/polymorphic interfaces, policy based design, the driver interface, and details on the implementation. Forward looking standards proposals, such as ranges and variants, will also be included in the discussion.

Turning Particle-Astro-Physicist-Hackers into Software Engineers

by Alex Olivas

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Want to increase software literacy in your organization? In this talk I'll present programs I've developed over the last year to teach C++ software engineering principles to graduate students and postdocs on the IceCube South Pole Neutrino Observatory. I believe similar programs could be beneficial to all types of organizations, from scientific collaborations to professional software shops.

IceCube is a kilometer-scale high energy neutrino observatory located deep in the Antarctic ice at the geographic South Pole. IceCube studies physics in energy regimes ranging from the most energetic processes in the visible universe (several orders of magnitude greater than the collision energies at the Large Hadron Collider), to dark matter detection at the 100 GeV scale. It is a relatively large collaboration, consisting of roughly 300 physicists and engineers from 48 institutions from a dozen different countries. IceCube has been collecting data for over 11 years (going into our 6th season with the fully completed detector) and is expected to run for at least another decade.

Many large scientific projects, which often run for decades, rely on code developed by hackers, who's focus and passion is rarely software engineering. Their primary passion, understandably, is the field for which they found themselves writing code. To make matters worse, the amount of work and focus required to secure a career in their chosen field often leaves little time and energy to devote to honing the skills needed to develop production quality code. Many students and postdocs often have, at best, a cursory understanding of the programming language(s) that comprise the experiment's codebase.

C++ has become the primary programming language for High Energy Physics (HEP) and will likely continue to be for decades to come. Consider, for example, that ROOT, GEANT, and Pythia to name a few critical HEP libraries are written in C++. Over the last year on IceCube, I've developed several comprehensive internal training programs in an attempt to bridge the gap between the scientist-hacker and the professional C++ software engineer. In this session I'd like to present the challenges I've encountered over the last year and my plans for extending these programs to the High Energy Physics community through the HEP Software Foundation.

The reviews have begun

by Jens Weller

From the article

A few weeks ago I announced a C++ review community, which since then has grown to 250+ members on reddit. There has been great feedback and discussions since then, so that the idea is now ready to be tested.  With August, the first review period has started

CppCon 2016: Asynchronous IO with Boost.Asio--Michael Caisse

Asynchronous IO with Boost.Asio

by Michael Caisse

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Reactive systems are found everywhere. The temptation to implement them with legions of waiting threads can be strong; however, the result is nearly always disappointing. The Boost.Asio library provides a framework to handle asynchronous resources with specific classes directed toward networking, serial port I/O, timers and more. In this session we will introduce Asio and some best practices while implementing a simple TCP client and server.

Asio has been submitted to the C++ Standards Committee for inclusion and can be found in the Boost library collection or as a stand-alone version. Come and learn a better way to implement reactive systems with the Asynchronous I/O library.

Qt talks at CppCon 2017

by Giuseppe D'Angelo

From the article:

The program for CppCon 2017 is now published!

CppCon is the annual conference for the C++ community: five days packed with over 100 talks, as well as inspiring keynotes, panel discussions, hallway chats, fun evening events and much more. CppCon is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to support the C++ software developer community and promote the understanding and use of modern, standard C++ on all compilers and platforms.
