Messaging with 0MQ (ZeroMQ) -- Richard Thomson

Utah C++ Programmers has released a new video:

Messaging with 0MQ (ZeroMQ)

by Richard Thomson

From the video description:

ZeroMQ (also known as ØMQ, 0MQ, or zmq) looks like an embeddable networking library but acts like a concurrency framework. It gives you sockets that carry atomic messages across various transports like in-process, inter-process, TCP, and multicast. You can connect sockets N-to-N with patterns like fan-out, pub-sub, task distribution, and request-reply. It's fast enough to be the fabric for clustered products. Its asynchronous I/O model gives you scalable multicore applications, built as asynchronous message-processing tasks. It has a score of language APIs and runs on most operating systems.

This month, Richard Thomson will give us an introduction to ZeroMQ. We'll look briefly at the low-level library libzmq before switching to the higher level C++ library zmqpp. We'll adapt a simple database for comic book issues into a CRUD server that responds to zmq messages.

CopperSpice: Comparison Operators: Breaking Change in C++20

New video on the CopperSpice YouTube Channel:

Comparison Operators: Breaking Change in C++20

by Barbara Geller and Ansel Sermersheim

About the video:

C++20 added a feature for the compiler to auto generate comparison operators which is often referred to as the spaceship operator. We found a way this can break existing code when supplying your own comparison functions. Watch our video to find out how this can happen in your existing code which has never used the spaceship operator before.

Cerealization and RPC with Cap'n Proto -- Richard Thomson

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.

CppCon 2022 endnote video posted: "Can C++ be 10x simpler and safer ... ?" -- Herb Sutter

The second video from CppCon 2022 has now been posted:

CppCon 2022 talk is online: “Can C++ be 10x simpler & safer ... ?”

by Herb Sutter

From the post:

It was great to see many of you at CppCon, in person and online! It was a really fun conference this year, and the exhibitor hall felt crowded again which was a good feeling as we all start traveling more again.

The talk I gave on Friday is now on YouTube. In it I describe my experimental work on a potential alternate syntax for C++ (aka ‘syntax 2’ or Cpp2 for short) and my cppfront compiler that I’ve begun writing to implement it...

Serialization with Boost.Serialization -- Richard Thomson

Utah C++ Programmers has released a new video:

Serialization with Boost.Serialization

by Richard Thomson

From the video description:

Many times you need a stable, versioned, archivable representation of your internal data structures. Serialization is one means of achieving this goal. Serialization is often used with REST APIs as a means of conveying data structures into and out of your application. XML and JSON formats are commonly used to encode your data structure. But serialization often is not just a data format.

How do you represent different versions of your data structures as they evolve over time? How do you ensure that old versions of your data structures interoperate with new versions of your data structures and vice-versa? While interoperability and backwards compatibility are an application responsibility, versioning itself is something you want from your serialization layer.

This month, Richard Thomson will give us an introduction to serialization via the Boost.Serialization library, one of the older and more mature boost libraries having first been contributed to Boost in 2002.
