C++ Weekly Episode 96: Transparent Lambda Comparators—Jason Turner

Episode 96 of C++ Weekly.

Transparent Lambda Comparators

by Jason Turner

About the show:

In this episode Jason explores the use of lambdas as comparators for the associative containers. Just how far can we take the use of lambdas? Variadic templates, forwarding references, multiple inheritance, variadic "using" declarations, local classes, transparent comparators and direct base class initialization are all utilized in this video.

Introducing Abseil, a new common libraries project—Titus Winters

A new library is out!

Introducing Abseil, a new common libraries project

by Titus Winters

From the article:

Today we are open sourcing Abseil, a collection of libraries drawn from the most fundamental pieces of Google’s internal codebase. These libraries are the nuts-and-bolts that underpin almost everything that Google runs. Bits and pieces of these APIs are embedded in most of our open source projects, and now we have brought them together into one comprehensive project. Abseil encompasses the most basic building blocks of Google’s codebase: code that is production tested and will be fully maintained for years to come.

What's new in clang-format 5

by Benoît Blanchon

From the article:

Clang 5 was released last week.
It's a good opportunity to talk about a not-enough-known tool: Clang-format.

Clang-format is part of the Clang project but can be used without the Clang compiler. It's an independent executable.

Clang-format is a code linter for C++. It takes a non-formatted code as input and produces a well-formatted code as output. The result is instantaneous.

Top 20 C++ multithreading mistakes and how to avoid them—Deb Haldar

You use threads? You should know this.

Top 20 C++ multithreading mistakes and how to avoid them

by Deb Haldar

From the article:

Threading is one of the most complicated things to get right in programming, especially in C++. I've made a number of mistakes myself over the years. Most of these mistakes were  luckily caught in code review and testing ; however, some arcane ones did slip through and make it into production code and we had to patch live systems, which is always expensive.

In this article, I've tried to catalog all the mistakes I know of, with potential solutions. If you know any more pitfalls, or have alternative suggestions for some of the mistakes – please leave a comment below and I'll factor them into the article.
