- How to Build an Image with the Dockerfile
- From building applications, installing dependencies and services, to automated deployment, and more - it all starts with Dockerfile. Let's review the syntax of Dockerfile, from basic to complexity, and some best practices when building Docker images. This guide will write a Dockerfile that guides Docker to select a minimized Linux (base image) for the applications we will deliver, and comes with our selected toolset and specific configuration to effectively build our own Linux distribution that distribution The version happens to be suitable for running our application. Key Points Docker uses the application to all its necessary binary files, runtime libraries, backend tools, operating systems

- 10 Examples of 3D Printing Transforming Our Reality
- 3D printing technology has made significant progress over the past decade, from technology that is only available to large manufacturers to technology that can be achieved in the office at home. It is becoming increasingly affordable and provides a fast way to create products. However, as innovation exceeds regulatory speeds, ethical, legal and ethical issues of 3D printing are becoming increasingly prominent. The following ten forms of 3D printing show that 3D printing will become as popular as other forms of manufacturing in the next few years. Important points 3D printing is becoming more affordable and easy to use, and its applications range from health science to architecture and even fashion. Bioprinting is a major breakthrough in the health sciences, and Wake Forest researchers have created a 3D bioprinter that can produce organs, tissues and bones, which can

- Understanding Java Variables and Data Types
- Core points Java variables are used to store a single data point or piece of information for later use. They must have a type, name, and some kind of data to be saved. The most widely used data type in Java is a character string, which is represented by Java's String class. Variables in Java can hold data that may change during the life of the program. Each Java variable has a default value; for String variables, it is null. If the value of a variable is not known at the time of declaration, Java can implicitly provide it with an appropriate default value. Java provides different data types to represent different types of data. For example, int data type represents an integer value, boolean can only be true or false
