Announced by Bloomberg this week, starts June 22:

Got What it Takes? Enter C++ Challenge for Chance to Attend CppCon

From the press release:

This summer, Bloomberg is hosting a weekly coding competition in partnership with the Standard C++ Foundation and CppCon, the flagship C++ conference. Part of Bloomberg’s overall CodeCon program, this contest will award seven problem solvers with a trip to Bellevue, Washington to attend CppCon in September 2015. The competition will be opened only to students currently enrolled in a university or college. Bloomberg CodeCon is a browser-based eLearning platform used by universities in their curricula, and powers coding challenges for college students in the US and Europe.

The series of seven weekly challenges will kick off on June 22, 2015, and each week contestants will be provided a different set of problems to solve via Bloomberg’s cloud-based CodeCon platform. Each week’s winner will earn a trip to CppCon in September. The list of seven winners will be announced and notified via email on August 5.

Additional coding contests will take place at the CppCon event in September for those who attend.

“We are excited to expand the types of competitions we can create and the opportunities CodeCon can provide to contestants,” said Rangan Prabhakaran, Bloomberg R&D developer and creator of CodeCon. “Focusing the competition to C++ and partnering with an industry leading conference like CppCon allows us to open greater opportunities for the programmer community at all skill levels.”

Keep an eye out for further contest details by following us on Twitter @BloombergLabs where we will be announcing the beginning of challenges – and make sure you are checking out the Bloomberg CodeCon site: http://codecon.bloomberg.com/.

Dive into C++14 - [2] - `for_each_argument` explained and expanded -- Vittorio Romeo

By Vittorio Romeo | Jun 10, 2015 01:27 PM | Tags: c++14

Vittorio Romeo covers in his second tutorial a very interesting code snippet originally posted on Twitter by Sean Parent `for_each_argument`.

Dive into C++14 - Part 2

by Vittorio Romeo

About the tutorial:

It shows and explains the usage of C++14 compile-time integer sequences, and analyzes a very interesting iterative implementation of an alternative version of Sean's function that takes the desired arity as a template parameter.

This tutorial video is a reviewed and improved version of my C++Now 2015 lightning talk ("`for_each_arg` explained and expanded").

Some possible use cases for the implemented functions are also shown and analyzed:

  • `make_vector(...)`
  • `forTuple` - iteration over tuple elements
  • `make_unordered_map(...)`

The target audience is people with knowledge of C++11 features and some C++14 experience.

CppCon 2014 A Deep Dive into 2 Cross-Platform Mobile Apps Written in C++--T. Grue & S. Kabbes

Have you registered for CppCon 2015 in September? Don’t delay – Early Bird 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:

A Deep Dive into 2 Cross-Platform Mobile Apps Written in C++

by T. Grue & S. Kabbes

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

At Dropbox we’ve spent the last year and a half building two cross platform mobile apps: the email client, Mailbox, and the photo gallery, Carousel. We started with the goal of a native look and feel with seamless performance but also needed to leverage a small team to build these apps on multiple platforms. We ultimately accomplished this by using C++ to share significant amounts of code in each app.

We’ll cover what portions of our apps we built in C++ and why we left some portions in the platform languages of Java and Objective-C, deep diving into some of the most important components. We’ll also discuss some unexpected benefits, areas we faced technical and human challenges, and some tips and tricks that you can use to leverage C++ to build very high performance apps.

10 tips to be productive in CLion

by Anastasia Kazakova

From the article:

Judging from my own experience as a developer, many C/C++ developers dismiss the idea that an IDE can make them more productive. Because what could be better than the simple and quick Vim or Emacs? Well, let me show you. These 10 CLion tips can take you to a new level of productivity, by letting you focus on the important and complicated tasks while the IDE handles routine jobs for you.
