Machine Code Explained

by Matt Godbolt

From the video:

In this video, Matt Godbolt appears on Computerphile to discuss their fascination with how computers work and their mental model developed in the 1980s, which still helps them understand modern computer systems. They use a simple analogy involving a robot with an abacus and pigeonholes to explain fundamental computer operations and how programs are executed. Matt then demonstrates how machine code, the computer's language, can be represented as a sequence of numbers and stored in memory to instruct the computer in performing tasks, illustrating the basic concept of programming.

CopperSpice: Generic vs Meta Programming

New video on the CopperSpice YouTube Channel:

Generic vs Meta Programming

by Barbara Geller and Ansel Sermersheim

About the video:

We released a new video which compares Generic and Meta Programming and how they are used in various computer languages like C++, Rust, and Go. In this video we also explain the definition of Template Meta Programming and when TMP is actually Reflection.

Simply using a template does not imply you are doing template meta programming and using a code generator does not mean you have implemented reflection.

Highlighting the current video releases for Meeting C++ 2023: the keynotes

With this year Meeting C++ had a unique set of keynotes, covering 6 impossible problems for software devs with the opening keynote by Kevlin Henney, followed by great wisdom about how open communities thrive by Lydia Pintscher. The closing keynote by Ivan Čukić was an impressive medley composing various idioms with Prog(ressive) C++.

All these keynotes are worth watching, a great contribution to our knowledge base as a community. Thanks to Kevlin Henney, Lydia Pintscher and Ivan Čukić for preparing these great presentations!

Promise-Cpp with Boost.Beast -- Richard Thomson

Utah C++ Programmers has released a new video:

Promise-Cpp with Boost.Beast

by Richard Thomson

From the video description:

Over the past few months, we've looked at asynchronous I/O and network programming using Boost.Asio and Boost.Beast. Those libraries connect to your application through the use of callbacks. When orchestrating a sequence of asynchronous operations, it is up to the application to ensure that the callbacks are invoked in the proper sequence.

This "callback hell" problem has long been recognized in the JavaScript world, as all I/O operations in JavaScript (timers or XML HTTP Requests) are asynchronous. In the JavaScript world this lead to promise oriented APIs that allowed for a more linear notation in expressing a sequence of asynchronous operations. This led to the Promises/A+ specification for JavaScript promises.

Promise-cpp is an implementation of the Promises/A+ specification for C++. It can integrate with Boost.Asio and Boost.Beast for asynchronous network programming support for low-level I/O as well as HTTP and WebSocket APIs.

New video on the CopperSpice YouTube Channel:

Time to Sort Out std::chrono

by Barbara Geller and Ansel Sermersheim

About the video:

We just posted a new video about std::chrono. It provides an overview of the functionality which was added in C++11, C++17, and C++20. Please watch to find out how much of std::chrono your compiler actually supports. We were pretty surprised at what we discovered.

Dynamic CUDA with NVIDIA's Runtime Compilation -- Richard Thomson

Dynamic CUDA with NVIDIA's Runtime Compilation

by Richard Thomson

From the video description:

Using CUDA is great way to accelerate tasks on the GPU. Regular CUDA programming compiles your C++ code into code that can execute on the GPU. But what if your problem domain is more dynamic and requires generation of code on the fly?

On the CPU you can use techniques like LLVM to compile code Just-in-Time (JIT) into the native CPU instruction set and call this code directly from your application. What about on the GPU?

The NVRTC (Runtime Compilation) library accepts CUDA C++ source code and creates modules of GPU ready code that you can execute on the GPU.

This month, Richard Thomson will give us an introduction to using the NVRTC library for runtime compilation and nvJitLink for runtime linking of CUDA C++ source code to execute code on the GPU. We'll use a simple fractal generator as the example, with a user provided "iteration formula" to generate a fractal image in the complex plane.
