Mixin Classes: The Yang of the CRTP—Jonathan Boccara

Some template tricks.

Mixin Classes: The Yang of the CRTP

by Jonathan Boccara

From the article:

Now that we’re clear on how the CRTP works, let me share with you another technique involving templates that is complementary to the CRTP: Mixin classes. I learnt about mixin classes by watching Arthur O’Dwyer’s Template Normal Programming talk at CppCon (actually you can find them in the slides because they were skipped over during the presentation)...

CppCast Episode 130: Reverse Debugging with Greg Law

Episode 130 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Dr. Greg Law from Undo to talk about the magic of reverse debugging and how it is becoming more widely known in the programming community.

CppCast Episode 130: Reverse Debugging with Greg Law

by Rob Irving and Jason Turner

About the interviewee:

Greg is the co-founder and CEO of Undo. He is a coder at heart, but likes to bridge the gap between the business and software worlds. (Sadly, these days most of Greg's coding is done on aeroplanes.)

Greg has 20 years’ experience in the software industry and has held development and management roles at companies including the pioneering British computer firm Acorn, as well as fast-growing start ups, NexWave and Solarflare. It was at Acorn that Greg met Julian and on evenings and weekends, they invented the core technology that would eventually become UndoDB. Greg left Solarflare in 2012 to lead Undo as CEO and has overseen the company as it transitioned from the shed in his back garden to a scalable award-winning business.

Greg holds a PhD from City University, London, that was nominated for the 2001 British Computer Society Distinguished Dissertation Award. He lives in Cambridge, UK with his wife and two children and in his spare time, catches up on email.

Red Hat at the ISO C++ Standards Meeting (Nov 2017): Parallelism and Concurrency—Torvald Riegel

Discover how C++ evolves:

Red Hat at the ISO C++ Standards Meeting (November 2017): Parallelism and Concurrency

by Torvald Riegel

From the article:

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in November 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. SG1 had a full schedule as usual, with Executors, Futures, and deferred reclamation mechanisms (e.g., RCU) being major discussion topics. We also started to track the state of proposals and topics we will need to discuss in a publicly accessible bug tracker...

C++17 Feature Removals And Deprecations—Stephan T. Lavavej

This is about visual studio, but this is also about how the deprecated mechanisms work.

C++17 Feature Removals And Deprecations

by Stephan T. Lavavej

From the article:

Technology advances by inventing new ways of doing things and by discarding old ways. The C++ Standardization Committee is simultaneously adding new features and removing old features at a gradual pace, because we’ve discovered thoroughly better ways of writing code. While feature removals can be annoying, in the sense that programmers need to go change old codebases in order to make them conform to new Standards, they’re also important. Feature removals simplify the Core Language and Standard Library, avoiding the doom of accreting complexity forever. Additionally, removing old features makes it easier to read and write code. C++ will always be a language that offers programmers many ways to write something, but by taking away inferior techniques, it’s easier to choose one of the remaining techniques which are more modern...

Compared to VS2015 Update 3, VS2017 15.5 provides on average an 8.9% increase in runtime speed in the SPEC 2017 benchmark..

5 ways how unique_ptr enhances resource safety in your code—Bartlomiej Filipek

Examples where unique_ptr shines:

5 ways how unique_ptr enhances resource safety in your code

by Bartlomiej Filipek

From the article:

While shared_ptr and weak_ptr are more complex, unique_ptr seems to be a perfect replacement for owning raw pointers. Not to mention is the fact that this pointer type is mostly a compile time “wrapper” and it cost almost nothing in the runtime.
