Utah C++ Programmers has released a new video.

Introduction to OpenCV with VcPkg and CMake

by Richard Thomson

From the video description:

OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library.

This month, Richard Thomson will give us an introduction to OpenCV and walk us through some examples of using the library. OpenCV is a large library, so not every detail can be presented at once. However, we'll try to get a feel for what it looks like to use components from the library and perform some simple image manipulation tasks.

CopperSpice: Memory Model to Mutexes

By Ansel Sermersheim | Mar 7, 2021 11:27 AM | Tags: None

New video on the CopperSpice YouTube Channel:

Memory Model to Mutexes

by Barbara Geller and Ansel Sermersheim

About the video:

We have released a new video which expands on our C++ Memory Model discussion. This section covers the usage of Mutexes and how they interact with the memory model. We define mutexes and locks, and pose some questions you may not have considered before.

Introduction to GPU Programming with CUDA and Thrust -- Richard Thomson

Utah C++ Programmers has released a new video from their February meeting.

Introduction to GPU Programming with CUDA and Thrust

by Richard Thomson

From the video description:

High-performance computing is now dominated by general-purpose graphics processing unit (GPGPU) oriented computations. How can we leverage our knowledge of C++ to program the GPU?

NVIDIA's answer to general-purpose computing on the GPU is CUDA. CUDA programs are essentially C++ programs, but have some differences. CUDA comes as a Toolkit SDK containing a number of libraries that exploit the resources of the GPU: fast Fourier transforms, machine learning training and inference, etc. Thrust is a C++ template library for CUDA.

In this month's meeting, Richard Thomson will present a brief introduction to CUDA with the Thrust library to program the GPU.

Programming the GPU with CUDA is a huge topic covered by lots of libraries, tutorials, videos, and so-on, so we will only be able to present an introduction to the topic. You are encouraged to explore more on your own!

Preconditions, Postconditions, Invariants - How They Help Write Robust Programs

By Andrzej Krzemienski | Feb 18, 2021 12:43 PM | Tags: None

An introduction to preconditions, postconditions and invariants.

Preconditions, Postconditions, Invariants –- How They Help Write Robust Programs

by Andrzej Krzemieński

From the video description:

Preconditions, postconditions, and invariants are part of what is often called Design by Contract, or Contract Programming. Even if you haven't heard of them, you are probably using them already. In this talk, we are going to see what they are, and how people and tools can make use of them.

Matching Text -- Richard Thomson

Utah C++ Programmers has released a video on Matching Text:

Matching Text in C++

by Richard Thomson

From the video description:

Many times in our code we need to validate a given piece of text against some pattern. We may only interested in validating that the text matches or we may be interested in extracting matched substrings from the whole string. We can write code from scratch to perform this matching or we can use libraries to tackle the problem. What library options are available to us in C++?

This month, Richard Thomson will give us a sampling of different methods we can use to attack the problem.

New video on the CopperSpice YouTube Channel:

Atomics

by Barbara Geller and Ansel Sermersheim

About the video:

We have released a new video which continues our C++ Memory Model discussion. This section covers the usage of Atomics and memory ordering. Do you know about the expected value in compare_exchange?

VcPkg: The Open Source Cross-Platform Package Manager from Microsoft -- Richard Thomson

Utah C++ Programmers has released a video on vcpkg:

VcPkg: The Open Source Cross-Platform Package Manager from Microsoft

by Richard Thomson

From the video description:

Richard Thomson gives us an informal introduction to vcpkg on both Windows and Linux.

Here's what we want from a package manager:
- works identically across platforms
- integrates with existing builds
- easy to find packages
- easy to consume packages
- can use prebuilt binaries to save build time
- can use local private packages as easily as public packages
- works with continuous integration systems
- doesn't require languages other than C/C++

How well does vcpkg fit the bill?
