When type inference fails -- Krzysztof Ostrowski

By fj | Nov 14, 2016 02:34 AM | Tags: None

C++11 re-introduces auto keyword that enables basic type inference. Using auto not only improves code readability.

When type inference fails

by Krzysztof Ostrowski

From the article:

Use of type inference puts impact on what is possible to be done with certain value, i.e. on its interface or concept it models, rather than on its concrete type. Unfortunately, auto does type inference locally, thus is not such powerful as we might expect. Here follows some examples of auto-inference failures.

Infographics: Operation Costs in CPU Clock Cycles--“No Bugs” Hare

A very interesting article about the cost of our basic operations.

Infographics: Operation Costs in CPU Clock Cycles

by “No Bugs” Hare

From the article:

Whenever we need to optimise the code, we should profile it, plain and simple. However, sometimes it makes sense just to know ballpark numbers for relative costs of some popular operations, so you won’t do grossly inefficient things from the very beginning (and hopefully won’t need to profile the program later �� )...

CppCast Episode 78: Kvasir with Odin Holmes

Episode 78 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Odin Holmes to talk about developing for Embedded Microcontrollers with C++ and the Kvasir library.

CppCast Episode 78: Kvasir with Odin Holmes

by Rob Irving and Jason Turner

About the interviewee:

Odin Holmes has been programming bare metal embedded systems for 15+ years and as any honest nerd admits most of that time was spent debugging his stupid mistakes. With the advent of the 100x speed up of template metaprogramming provided by C++11 his current mission began: teach the compiler to find his stupid mistakes at compile time so he has more free time for even more template metaprogramming. Odin Holmes is the author of the Kvasir.io library, a DSL which wraps bare metal special function register interactions allowing full static checking and a considerable efficiency gain over common practice. He is also active in building and refining the tools need for this task such as the brigand MPL library, a replacement candidate for boost.parameter and a better public API for boost.MSM-lite.

Do you know how a program ends?

Terminators

A GraphViz diagram that shows both normal and unexpected program termination flows in C++.

There are multiple ways a C++ program may terminate. These include both normal and unexpected termination.
This GraphViz diagram shows the program termination flows as defined by the standard...

Why you should use Boost.MultiIndex (Part I)--David Gross

Did you know that container?

Why you should use Boost.MultiIndex (Part I)

by David Gross

From the article:

Although Boost.MultiIndex is a pretty old library — introduced in Boost 1.32, released in 2004 — I found it rather unsung and underestimated across the C++ community in comparison to other non-standard containers.

In this article, split into multiple parts, I will highlight all the benefits you can get using boost::multi_index_container instead of the standard containers: faster, cleaner and simpler code.

From the article:

Today I updated Compiler Explorer to support better sharing, specifically to allow embedding a Compiler Explorer view into another site, useful for blog posts that wish to demonstrate how compilers generate code, or how language constructs actually become assembly...
