How can I copy a file from one folder to another folder within a container in Docker?
Introduction In this article, we are going to discuss “How to transfer files as well as directories from the host operating system to the Docker container environment.” The need for all these commands is that many times developer has to provide various types of files to the Docker container, these files are configuration files, security and authentication files, application files, and many more. So, this is a very simple and important task that needs to be performed while creating or after the creation of the Docker container on the Docker daemon. Some commands are also going to be used while ...
Read MoreTop 10 Open-Source IoT Frameworks
Introduction You might have heard about the internet of things (IoT), but what exactly is it? Simply put, IoT is the network of physical objects such as cars, appliances, industrial equipment, medical devices, and so on that are embedded with electronics, software, sensors, and connectivity that enables them to collect and exchange data. Overview of IoT Frameworks There are a few different ways to build your connected devices and applications when it comes to the Internet of Things (IoT). One option is to use a pre-made IoT framework, saving you time and effort in development. Let’s take a look at ...
Read MoreHow to run amd64 Docker images on the arm64 host platform?
Before knowing how to run amd64 docker images on the arm64 host platform, we must know what this means. There is a term called multi-architecture or multi-platform docker container images. These images contain the ability to run on various base or host architectures provided at the time of containerization of the images. Need of Multiplatform images Suppose you are a DevOps engineer and you have to prepare a web-server for an IT company. You have an amd64 host platform but when you handed over the image to the company you came to know that the company only works on the ...
Read MoreHow to run Gunicorn on Docker?
In this article, we are going to learn about how to run Gunicorn on Docker. Before creating the docker container with the gunicorn functionalities, we must know some of the basics of web servers and gunicorn. Introduction to Gunicorn Let us suppose we have a web server that shows the output of a python code to the users. This web server will execute the python script each time a request came to it, this will cause it to restart, overload, and delay (heavy delay for huge scripts) in response. So the real problem here we have is a static server ...
Read MoreHow to Hot-Reload in ReactJS Docker?
Hot-Reloading is adding dynamic functionality to the react application on the web browser. This means if we change something in the code of the application it immediately reflects this change on the web application front. But before “reloading” anything we must know “loading”, that is to make some ReactJs project on the Node Docker container. Creation and Containerization of React App Step 1: React app Use the prebuild commands to create a basic react application. Example $npx create-react-app reactapp Output npx: installed 67 in 19.076s Creating a new React app in /home/hemant/project/reactapp. Installing packages. This might take ...
Read MoreDifference between Open Source and Proprietary Software
Technology is something that has a significant impact on each and every one of our lives. Due to the large number of devices that we all interact with on a daily basis, we are exposed to a wide variety of software. We are able to complete a variety of tasks with the assistance of software.Software is an essential component that grants its users the ability to operate and carry out any designated activity. The difference between open-source software and proprietary software is a significant one in the software industry. Read through this article to find out how an open-source software ...
Read MoreFreeware v/s Shareware
Softwares are a set of programs that are created in order to perform a specific computer task. Generally, the software is created by developers to solve the needs of its users. And based on the restrictions that are imposed on software. Basically, there are a few categories based on licensing. Here, we will compare two types: Freeware and Shareware.Freeware SoftwareThese softwares are the softwares that are available to the users free of cost to use and distribute. The source code of the software is not available to use and cannot be modified.Shareware SoftwareThese softwares are the softwares that are initially ...
Read MoreSciPy is built upon which core packages?
SciPy is built upon the following core packages −Python − Python, a general-purpose programming language, is dynamically typed and interpreted. It is well suited for interactive work and quick prototyping. It is also powerful to write AI and ML applications.NumPy − NumPy is a base N-dimensional array package for SciPy that allows us to efficiently work with data in numerical arrays. It is the fundamental package for numerical computation.Matplotlib − Matplotlib is used to create comprehensive 2-dimensional charts and plots from data. It also provides us basic 3-dimensional plotting.The SciPy library − It is one of the core packages providing us many user-friendly and ...
Read MoreWhat are various sub-packages in Python SciPy library?
To cover different scientific computing domains, SciPy library is organized into various sub-packages. These sub-packages are explained below −Clustering package (scipy.cluster) − This package contains clustering algorithms which are useful in information theory, target detection, compression, communications, and some other areas also. It has two modules namely scipy.cluster.vq and scipy.cluster.hierarchy. As the name entails, the first module i.e., vq module supports only vector quantization and k-meansalgorithms. Whereas the second module i.e., hierarchy module provides functions for agglomerative and hierarchical clustering.Constants(scipy.constants) − It contains mathematical and physical constants. Mathematical constants include pi, golden and golden_ratio. Physical constants include c, speed_of_light, planck, gravitational_constant, etc.Legacy ...
