The behavior of the Windows scheduler changed significantly in Windows 10 2004, in a way that will break a few applications, and there appears to have been no announcement, and the documentation has not been updated. This isn’t the first time this has happened , but this change seems bigger than last time. The short version is that calls to timeBeginPeriod from one process now affect other processes less than they used to, but there is still an effect.

In my experiences of planning for testing in various environments, and across several teams and organizations, the value of that planning was never the document itself; rather, it was the thoughts and consideration of the activities, resources and potential risks and issues yet to be discovered. Thinking deeply about all of those things and writing them down, in whatever form the final document took, was the real value of the exercise.

Over the last several months we’ve been noticing that some of our customers were having trouble with the performance of some of their sagas. Invariably, the sagas that were at fault were examples of the scatter-gather pattern, and the ultimate culprit was contention at the storage level due to the optimistic concurrency strategy that was being used.

Application development has evolved, and therefore new needs have arisen when it comes to testing and new tools to deal with them. Let’s take a look!

Because although the literature talks about the evolution of development from monolithic applications to applications based on microservices, in reality, we often find ourselves with the integration of

Testers, in their day-to-day lives, have to do many types of tasks. And to enable them to do those tasks there are many tools in the market too. These tools usually specialize in helping the testers perform a certain task. Sometimes these tools can be used to completely automate the tasks while at other times these tools can make the tasks easier. In this article we will try to broadly categorize these tools.

Dynatrace news. Kubernetes at scale in the enterprise is complex. Systems are constantly changing, with pods existing only briefly to perform tasks before they’re terminated. In such circumstances, it’s challenging to investigate the reasons for unexpected behavior or traffic between pods. Dynatrace is the only Kubernetes monitoring solution that provides continuous automation and full-stack automated observability without changing code, container images, or deployments.
