These services allow users to stream or download content across a broad category of devices including mobile phones, laptops, and televisions. However, some restrictions are in place, such as the number of active devices, the number of streams, and the number of downloaded titles.

Suppose we need to sort the collection by multiple keys. In C#, we can do this with the help of OrderBy().OrderBy() or OrderBy().ThenBy(). But what is the difference between these calls? To answer this question, we need to delve into the source code.

As companies accelerate digital transformation, cloud services such as AWS Lambda help companies to modernize their application architectures to quickly adapt to the needs of their customers while offloading the operational complexity to their cloud vendor. With the growing complexity of application architectures which can rely on tens of thousands of microservices, end-2-end observability is a requirement to optimize application performance and to deliver intelligent root-cause analysis.

Major catastrophes can transform industries and cultures. The Johnstown Flood, the sinking of the Titanic, the explosion of the Hindenburg, the flawed response to Hurricane Katrina–each had a lasting impact. Even when catastrophes don’t kill large numbers of people, they often change how we think and behave. The financial collapse of 2008 led to tighter regulation of banks and financial institutions.

We described the tools and techniques we use to gain insight within each domain. There is, however, a class of problems that requires an even stronger level of magnification going deeper down the stack to introspect CPU microarchitecture.
