From time and again, I've worked with several Fortune 5000 startups. The most common problem that we've dealt with is microservices testing. While transitioning to a microservices architecture, I've observed teams running into issues where they haven't planned out which testing strategies they want to use. This is especially true for a team that is brand new to microservices.

This car would definitely require synthetic testing. There are two main modes for collecting data about your systems and software: the first is by collecting data from within the application itself, often called white-box monitoring, and the second is by querying the system from the outside and collecting data about the response.

Yesterday, I received this question from a distinguished C++ expert who served on the ISO C++ committee for many years. The email poses a decades-old question that still has the classic roll-your-own answer in C++ Core Guidelines #C.130 , and basically asks whether we’ve made significant progress toward automating this pattern in modern C++ compared to what we had back in the 1990s and 2000s.

What is AI? In layman terms, AI or Artificial intelligence is the area of computer science that focuses on making machines “intelligent.” And by intelligence, it means making the system capable of learning and taking decisions like humans. Thus, an AI-enabled machine will be able to learn how to react in particular situations and then take decisions in the future according to its learning.

The typical journey for a person browsing a website: view a page, click a link, browser loads new page. That's assuming no funny business like a Single Page App, which still follows that journey, but the browser doesn't load a new page — the client fakes it for the sake of a snappier transition. What if you could load that new page before the person clicks the link so that, when they do, the loading of that next page is much faster?
