Blob storage is an object storage service you use in Azure. It is designed for storing large volumes of unstructured data, including text, binary data, images, and text. In this service, your data is stored in containerized blobs with a directory-like structure. You can use blob storage to ensure flexible access to storage, high availability, and data consistency. Read on to learn how you can use C++ with Azure storage...

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

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...
