Constructor Failures--Arne Mertz

By Adrien Hamelin | Feb 1, 2016 01:08 AM | Tags: intermediate

Constructing or not constructing, that is the question.

Constructor Failures

by Arne Mertz

From the article:

Sometimes we fail to acquire a needed resource or responsibility during the construction of an object. Sometimes the construction of a subobject fails. How can we deal with an incompletely constructed object?

 

Experiments in partition and remove -- Brent Friedman

An analysis and exploration of partition and remove algorithms. By combining aspects of these two, we rediscover useful algorithms that the Standard Library doesn't have.

Experiments in partition and remove

by Brent Friedman

From the article:

The C++ Standard Library exposes dozens of powerful algorithms for use in everyday software. Two of these algorithms, partition and remove_if, provide similar functionality for segregating data. If we dig carefully into implementations of these algorithms, a certain symmetry is exposed. This exploration will lead us to the discovery of useful algorithms that we can employ in our daily engineering work.
This article demonstrates particular algorithm implementations — but it is important to remember that the source code will vary between different implementations of the standard library, and can differ based on what sort of data you pass in.

Episode 43 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Matt Godbolt to discuss the online Compiler Explorer project.

CppCast Episode 43: Compiler Explorer with Matt Godbolt

by Rob Irving and Jason Turner

About the interviewee:

Matt is a developer at trading firm DRW. Before that he's worked at Google, run a C++ tools company, and spent over a decade in the games industry making PC and console games. He is fascinated by performance and created GCC Explorer, to help understand how C++ code ends up looking to the processor. When not performance tuning C++ code he enjoys writing emulators for 8-bit computers in Javascript.

Using parallelism with boost::future

by Jens Weller

From the article:

... While I'm fine with that the application locks up kind of hard during writing a GB zip file (its only job), I'd like to be as fast as possible. Thats why I decided to parallelize the part of the application that reads the file paths via boost::filesystem...
