In this article, we’ll explore how C++’s abstraction model heavily relies on compiler optimizations, unveiling some unfortunate examples of unexpected performance loss. Afterwards, we will compare how the three major compilers (GCC, Clang, and MSVC) fare in this area, and we’ll discuss some potential future improvements or workarounds.
the sad state of debug performance in c++
by Vittorio Romeo
From the article:
C++ developers should know that `std::move(0)` is semantically the same as `static_cast<int&&>(0)`, and most of them would expect the compiler to generate no code for the move, even with optimizations disabled. Turns out that GCC 12.2, Clang 14.0, and MSVC v19.x all end up generating a call instruction. [...]

Utah C++ Programmers has released a new video.
Cerealization and RPC with Cap'n Proto
by Richard Thomson
From the video description:
Cap'n Proto is a serialization and RPC (remote procedure call) framework built by the primary author of Google's Protobuf. "Cap’n Proto is an insanely fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster." (Cap'n Proto's web site refers to serialization as "cerealization" in a tongue-in-cheek fashion.)
Cap'n Proto is designed for the use case of efficiently transmitting complex message structures across the network as part of a distributed system. So while it is a serialization method like converting your data structures to JSON, it is more explicitly designed for network oriented messages and remote procedure call scenarios. It is also designed with efficiency in mind.
This month, Richard Thomson will give us an introduction to Cap'n Proto using a fictional comic book database as an example. We'll use Cap'n Proto to model some simple CRUD (create, read, update and delete) operations over RPC. We'll look at how application data structures are represented using Cap'n Proto.

Do you know about std::ssize()?
Reducing Signed and Unsigned Mismatches with std::ssize()
by Bartlomiej Filipek
From the article:
In this article, I’ll show another technique that avoids mixing signed and unsigned types.
In my article Integer Conversions and Safe Comparisons in C++20 we learned about
cmp_*integer comparison functions that allow us to compare various types of integer types. The functions are safe because they help with mixing signed and unsigned types. In C++20, there’s another handy feature: the non-memberstd::ssize()function that returns a signed number of elements in a container.Let’s see how to use it...
