linked with record-type systems, which can process data and transactions.3) build an open ecosystem and platform for product development to accelerate innovation and growth: developers hope to support the cloud era through dynamic application development environments. The new development platform should be open and flexible, so that internal developers and independent development companies can easily create applications and connect them to existing computing systems. In the face of these market

RxJava development essentials 6-combination of Observables In the previous chapter, we learned how to convert observability sequences. We also sawmap(),scan(),groupBY()And more examples of useful functions. They help us operate the Observable to create the Observable we want. In this chapter, we will study combined functions and learn how to process multiple Observables at the same time to create the desired Observable.Merge This scenario is often cre

, although there is a clear division of responsibilities between different teams, there is a lot of flexibility in the middle part of the coordination. In addition, the development, operations and testing teams in the core of the team has a sense of identity, everyone started with the goal is to run the company can succeed, this is not the root cause of the problem of cooperation. This is actually similar to the core point of DevOps, so why not revisi

the probability is different. To describe this probability, we need to introduce a confuse matrix, also known as the emission matrix. It is used to describe the probability of producing moss in different weather conditions, as shown in figure 4. Figure 3 Relationship between weather and observation The confusion matrix describes the third parameter of HMM, usually called B. Assume that there are m observability states, the confusion matrix is a mat

question: how to identify, locate, and combine these components into a running application. Most traditional systems define an application as a single process instead of a group of loosely coupled services that work together. This leaves the combined tasks to the Application designers. DSS supports creating, managing, deploying, and running applications composed of loosely coupled services by protocols and runtime. The service is created at runtime and connected according to the descriptions of

The graphic description of the wex5 tutorial shows the cluster application and binding technology of the object, and the wex5 Cluster I. Preface: In the official wex5 tutorial, the beginning is an example of input and output real-time output, showing the concept of an object that can be observed. In the future, I will use a lot of observability objects in my project development. So the question is: 1. What is an observed object? 2. What can an observe
