C++ String Benchmark: STL vs. ATL vs. Custom Pool Allocator
by Giovanni Dicanio
From the article:
I was curious to compare the performance of the STL string implementation versus ATL CString, using Visual Studio 2019, so I wrote some simple C++ benchmark code for this purpose. I also added into the mix a custom string pool allocator.

Template Metaprogramming - How it All Started
by Rainer Grimm
From the article:
Metaprogramming is programming on programs. C++ applies metaprogramming at compile time. It started in C++98 with template metaprogramming, was formalized in C++11 with the type-traits library, and since C++11 has steadily improved. The main driving force is constant expressions. In this post, I want to write about its roots...

Tripreport: virtual CppCon 2021
by Jens Weller
From the article:
I attended this weeks virtual CppCon partially, as I'm also very busy with my upcoming conferences: Meeting Embedded & Meeting C++ 2021. Still I had a lot of fun. Thanks to Jon Kalb, the volunteers, speakers and all the attendees who made CppCon 2021 possible!

Technical organizations today depend more and more heavily on their server infrastructure. In this environment it is critical to have a server infrastructure that not only is robust and reliable, but that is both flexible and secure.
The Standard C++ Foundation has relied on DigitalOcean cloud services for its server infrastructure since 2014. Standard C++ Foundation relies on its DigitalOcean servers to support its document repositories, file sharing, messaging systems, mailing lists, DNS, Firewalls, and websites.
The Standard C++ Foundation server infrastructure is made up of seven DigitalOcean Droplets, which are Linux-based virtual machines (VMs) that run on top of virtualized hardware. Each Droplet can be set up either as a standalone dedicated server, or as part of a larger cloud-based infrastructure.
Resizing a server, also known as vertical scaling, increases the amount of resources a server has. A key benefit of using DigitalOcean Droplets is their flexibility, as they can very easily be resized based on changing needs. Running a large event or expect a big bump in web traffic? Easily increase your Droplet’s CPU and RAM to get the speed and bandwidth you need, then dial it back down when your needs go back to normal. Or increase your Droplet size as your organization grows, increasing the RAM and CPU, and also permanently increase the size of a Droplet’s disk. Whichever type of increase you need, it’s all down with an easy change of settings in your dashboard.
Co-locating a server infrastructure does not mean giving up control. DigitalOcean Droplets can be controlled either through an API or through doctl, their command line interface client.
In the seven years that Standard C++ Foundation has been a DigitalOcean customer, they have added most of their key functions onto its cloud-based DigitalOcean servers.
Following are the key areas in which the Standard C++ Foundation has come to rely on DigitalOcean:

Meeting C++ is looking for C++ employers to join the next online C++ job fair in mid November.
Looking for Employers for the online C++ job fair
by Jens Weller
From the article:
The Meeting C++ online job fair is in two weeks, and so far I only have one company interested in a free table as of today.
The job fair is on November 16th (afternoon CET) and 17th (evening CET). Sponsors will also be listed on the website with logo in the job section and at the job fair page. During the event your table will be above the free tables and you'll receive CVs through the tooling of Meeting C++ from the moment of signup to friday after the week of the event. The last job fair had 82 folks from 26 countries submit. These sponsorships are also what allows me to work on the tooling and improve the process further, some funding of the sponsorships also goes into advertising of the event.

CppCon 2021 Virtual Trip Report, A User Story
by Javier Estrada
From the article:
This is the first CppCon hybrid (in person and virtual) conference, and in my opinion, it was a success in terms of content and organization, particularly from the virtual side. Sure, there were the occasional quirks, or the first day emergencies if one didn’t read the “instruction manual” (ahem) beforehand. But ’nuff said.
I’m writing this trip report while the experience is fresh, and before the glitter fades, drinking a hot cup of coffee while everybody else sleeps...

C++ 20 Concepts part 1 and part 2
by Gajendra Gulgulia
From the article:
Concepts is one of the 4 major additions in C++20 standard. The idea of concepts has existed as long as C++ templates themselves but it has only been until few years that the foundation of C++ concepts have been laid out in the manner it had earlier been desired desired, i.e., in coherence with C++ templates design principles:
- a generalized code
- better code than hand written code with zero overhead
- well specified interfaces on the template method/class usage.
C++ templates fell short on the last requirements but the first two requirements were good enough and templates few off with a huge success. In simpler terms the last requirement on concepts is about imposing constraints on the template parameters themselves, that a function or a class can accept.
In this article, I’ll give an introductory example of how concepts could be useful in terms of specifying the interface of a generic code, which amongh many advantages helps get rid of the verbose error message and achieve faster compilation, and consequently help make generic programming more expressive and fun. In the later long running series about concepts with gradually increasing complexity, I’ll present details as and when necessary. Lastly before beginning, I encourage all users to try out the code examples with a compiler that supports C++20 . So lets start with concepts of concepts
