5 Advantages of C++ Lambda Expressions and How They Make Your Code Better
by Bartlomiej Filipek
From the article:
The mixture of brackets in the preceding line become one of the most noticeable indications of Modern C++.
Yep.
Lambda Expressions!
It might sound like I’m trying to create a new blog post about something that everyone knows. Is that true? Do you know all the details of this modern C++ technique?In this article, you’ll learn five advantages of Lambdas. Let’s start...

C++20: A Simple math Module
by Rainer Grimm
From the article:
Modules are one of the four prominent features of C++20. They overcome the restrictions of header files and promise a lot: faster build-times, fewer violations of the One-Definition-Rule, less usage of the preprocessor. Today, I want to create a simple math module...

C++ on Sea will now be a virtual conference, held July 15th-17th (with workshops the following week).
C++ on Sea moves online - and into July
From the article:
We decided to move the workshops a little further away, since we no longer have the constraints imposed by venue, accommodation and travel - but we do want to reduce the number of consecutive days people will need to spend watching online.
The workshops will also run on different days from each other - so, potentially, you could attend more than one!

Detect C++ buffer overflows in most POSIX functions
By G. Ann Campbell
From the article:
Buffer overflows have been responsible for some of the most notorious crashes, worms, and hacks for more than 30 years, including the Morris worm, the Code Red worm, and the ping of death. More recently, VPNs have been compromised via buffer overflow; an overflow-related code execution flaw was found in macOS Mojave (fixed in Catalina); and a WhatsApp buffer overflow exposed users' private messages, location, and even camera and mic feeds. In short, buffer overflows aren't just bugs that could crash your program; they also represent serious threats to security. That's why we're excited to announce the availability of a new C and C++ rule to detect overflows in most POSIX functions: S5782, "POSIX functions should not be called with arguments that trigger buffer overflows".

Ray-tracing in a Weekend with SYCL: Basic sphere tracing
by Codeplay
About the article
C++ Ray-Tracing in a Weekend by Peter Shirley is a great resource to start learning about ray-tracers and how to implement one, and at the same time providing all the source code in a GitHub repository . You can find more information about his books on ray-tracing techniques with accompanying implementations on his blog, and you can also download the books as .pdf, or load them on your Kindle device for free from the GitHub project.
The main goal of this blog post is not to teach the concepts of ray-tracing, Peter does a great job of that, but provide a walk-through tutorial on how to accelerate practical applications and algorithms using SYCL.
