Finding build bottlenecks with C++ Build Insights--Kevin Cadieux
Did you try it?
Finding build bottlenecks with C++ Build Insights
by Kevin Cadieux
From the article:
C++ Build Insights offers more than one way to investigate your C++ build times. In this article, we discuss two methods that you can use to identify bottlenecks in your builds: manually by using the vcperf analysis tool, or programmatically with the C++ Build Insights SDK. We present a case study that shows how to use these tools to speed up the Git for Windows open source project. We hope these tutorials will come in handy when analyzing your own builds...

The benefits and challenges of online live training -- Mateusz Pusz
Read about the benefits and challenges of online live training:
The benefits and challenges of online live training
by Mateusz Pusz
From the article:
Last week Jason Turner, Nicolai Josuttis, Rainer Grimm, Klaus Iglberger, and Mateusz Pusz met with the hosts of cpp.chat to talk about why training is valuable and to explain the particular challenges of such a profession in the days of social distancing.
Among others, C++ trainers discussed the benefits and issues with delivering the trainings and workshops in the online form. It turns out that online live training does not have to be a worse experience than participating in the face-to-face one. Read more...
Trip report: C++ Siberia 2020--Timur Doumler
Did you attend?
Trip report: C++ Siberia 2020
by Timur Doumler
From the article:
In 2019, I had a very busy conference year. I had just become self-employed, which meant I did not have to ask anyone’s permission anymore to go to a C++ conference. And because conferences are fun, I decided to go to all of them. Well, not all of them, but I ended up speaking at quite a few that year: CppOnSea (Folkestone), ACCU (Bristol), using std::cpp (Madrid), 4Developers (Warsaw), C++Now (Aspen), CoreC++ (Tel Aviv), C++Russia (both of them – Moscow & St. Petersburg), CppCon (Denver), ACCU Autumn (Belfast), MeetingC++ (Berlin), and finally CoreHard (Minsk). The latter one was particularly memorable because it was the first time a C++ conference invited me to deliver the opening keynote (and it was an amazing experience – thank you!)...
Qt, range-based for loops and structured bindings--Ivan Čukić
Do you have that problem?
Qt, range-based for loops and structured bindings
by Ivan Čukić
From the article:
Qt has a long history. The first stable version was released before the first version of C++ was standardized and long before the different C++ compiler vendors started shipping usable implementations of the C++ standard library. Because of this, Qt often followed (and still follows) some design idioms that feel unnatural to the usual C++ developer.
This can have some downsides for the Qt ecosystem. The evolution of the C++ programming language which sped up quite a bit in the last decade often brings improvements which don’t fit well with the Qt philosophy. In this blog, I offer some ways to work with this...

Online live trainings at Train IT
Train IT went online:
Online Live Trainings with Train IT
by Mateusz Pusz
From the article:
Traditional workshops are so-called "Closed Trainings". They are requested by a specific company, are delivered at its premises, and are provided only for its engineers, which means that they are closed to external participants.
On the other hand, "Open Trainings" are open to everyone but are harder to organize, thus provided less often. Additionally, they require participants to travel to a distant place of training, which besides additional time needed for it, also adds travel and accommodation costs to the training's registration fee.
Open Online Live Training joins the best parts of both cases. Read more...
