Cross-Platform Apps with Dropbox’s Djinni: In-Production Architecture Examples
Djinni is a tool developed by Dropbox for cross-platform C++ development. This session will give an overview of mobile cross-platform C++ development, an explanation of what Djinni does and why it is useful, and details on several Djinni-based app architectures I have used.

- Mobile C++ Architecture Overview
- What is Djinni?
- Example 1: "Hello World"
- Example 2: User Preferences
- Example 3: Google Analytics
- Challenges Encountered
- Additional Resources

Using IncludeOS to Write Fast and Secure Web Applications
Have you ever tried writing a web application with C++? Can opening a file and serving it via HTTP be as simple as writing 20 lines of python? With the undeniable importance of web development, C++ can not allow itself to ignore such an important field, especially with the rising competition in the field of system programming languages, coming from Rust, D and Go.

Join us as we explore modern approaches to asynchronous IO, socket communication the advantages and disadvantages of using a unikernel and their respective performance implications.

We'll also take a look at how future iterations of the C++ standard library, could solve some of those problems.

Effective Qt (2017 edition)
The title of this talk pays tribute to the "Effective Qt" columns, a series of blog posts started by Marc Mutz many years ago, whose title was in turn inspired by Scott Meyer's book series. The purpose of the columns was to provide in-depth explanations about Qt data structures and design patterns to C++ developers, who wanted to know more about how to use Qt core classes, and how to use them "effectively".

This talk aims to be an up-to-date version of (some of) the advices in the columns, in the light of the major changes introduced to core classes in Qt 5's lifetime (including changes that will come with Qt 5.10, scheduled to be released at the end of 2017).

Moreover, we will see how the language and Standard Library features added to latest C++ standards interact with long-established practices when developing Qt code.

The talk is structured as a series of best practices, guidelines and tips&tricks, learned from many years of experience developing Qt-based projects, as well as the significant effort spent developing Qt itself and steering its evolution. For each advice, a technical discussion of the rationale behind it will be provided, and possibly some indication about future developments and what to expect in upcoming Qt versions.

The topics mentioned in this talk cover many areas in Qt, and should contain something new or interesting for Qt developers using C++, hopefully helping them to build quality libraries and applications. The main focus areas will be around Qt containers (and their algorithms) as well as Qt string classes.

Attendees are expected to have some working knowledge of Qt C++ APIs (and especially C++ APIs in QtCore).

Qt as a C++ Framework: History, Present State and Future
Qt is one of the largest and most widely used C++ frameworks. It is fully cross-platform, covering all functionality required to develop advanced graphical applications. The talk will go through important parts of Qt's history from it's roots to what it is today. We will have a look into the relation between Qt and C++, some of the design philosophies driving the evolution of Qt. I'll go through the current state of the frameworks, latest releases, ongoing development focus, and give an outlook into the future.

Inside the Qt Object Model
Programming your application with Qt means that you will sooner or later encounter the central QObject class, signal & slot connections, or generic properties. The object model makes it safe and easy to develop with components.

In this session we will take a look at the implementation of these features. For example, how emitting a signal with one line of code results in calling the right slot elsewhere. This is even possible when the sender lives in a different thread than the receiver. In addition, we will learn how reading and writing properties works behind the scenes.
