Safe Numerics Library

by Robert Ramey

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

This presentation describes the necessity, utility and usage for a library of safe integer types. These types function in all respects the same way as built-in integers, but guarantee that no integer expression will return an incorrect result. The library can be reviewed at the boost library incubator.

C++17 Features And STL Fixes In VS 2017 15.3--Stephan T. Lavavej

It's always getting better!

C++17 Features And STL Fixes In VS 2017 15.3

by Stephan T. Lavavej

From the article:

Visual Studio 2017’s first toolset update, version 15.3, is currently in preview and will be released in its final form very soon. (The toolset consists of the compiler, linker, and libraries. After VS 2017 RTM, the 15.1 and 15.2 updates improved the IDE. The 15.3 update improves both the IDE and the toolset. In general, you should expect the IDE to be updated at a higher frequency than the toolset.)

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

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.
