If we're going to use a NoSQL DB for our app, then we want something fast and easy to use. We learn that "NoSQL" doesn't necessarily imply "no maintenance". We think about using managed hosting services like MongoDB's Atlas or Amazon's DynamoDB, but we choose to host it ourselves, whether on our premises or in our own cloud instance. We evaluate several NoSQL options including Redis and Cassandra and pick MongoDB. We may be able to get it installed by installing it from our Linux distribution, using Mongo’s repositories, or using a snap. But if something goes wrong, we might ... Read More
Both multiprocessors and multicomputers are the types of parallel computing systems. The basic difference between a multiprocessor and a multicomputer is that a multiprocessor is a single computer system containing multiple processors interconnected with the common I/O and memory devices, whereas a multicomputer is a system consists of several autonomous computers connected in a network and each computer has its own I/O and memory devices, and other computing resources. Read through this article to find out more about multiprocessors and multicomputers and how they are different from each other. What is Multiprocessor?

Some software reads an entire input file into memory before processing it. If the input file contains a very long string, the software may crash if there isn't enough memory to hold the entire string. We’ll look at ways to change a single character in a very large one-liner file in Linux. Some applications cannot handle very large one-liners, so we’ll examine our options. Target File Some modern JavaScript frameworks compress all of the code onto a single statement. Let’s say we have a one-liner of JavaScript code called original.js with an error in it. It calls “fliter“ instead of ... Read More

A Linux command that you run from a terminal window can be built-in (a part of the system), a function (an application that runs when you enter certain commands), an alias (another name for a command), or an external executable (a program that you download). You can use the which, command, whereis, whatis, and type tools to determine what each one is and where they are located. We will look at the which, command, types, and whereis commands as they are usually found in most Linux-Based OSs. So let’s explore how to get the path of a Linux command in ... Read More
