Raspberry Pi 4 was released today with amazing new features and upgrades. Let us find out what is new and how we can buy Raspberry Pi 4 right now. Raspberry Pi Series We have written a series on Raspberry Pi. So if you want to read in detail about Raspberry Pi, a great $35 computer, then visit the series page. Raspberry Pi 4 features at a glance * * * * * * * * * * * 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU * Up to 4GB of LPDDR4 SDRAM * G
![Basic Calculator Program - BASH Example Project [Part 8]](/content/images/wordpress/2019/06/Basic-Calculator-Program-Learn-Bash-1.png)
We will build a bash example project, calculator program and at the same time reinforce all the concepts already taught. In a quick summary, we’ve explored the fundamental topics on variables, decisions, control statements, and arguments. There were minor subtopics including using comments in bash programs and operator types. Make sure to refer to previous articles in case you need to relearn any topic. * Algorithm or procedure * Coding * Some clarification * infi
Welcome to the Arguments chapter of the BASH scripting series. This chapter will introduce you to another new method of getting user inputs for your script. In the previous chapter, we’ve used the read command to get user inputs. Our bash interpreter invokes the read command works after our bash program, i.e., user input is prompted after the program is run. Still, we are interested in getting input parameters or arguments, so our program will process them later. What are arguments
We have already discussed the while loop in our previous article. In this article, we will be covering the for loop. The for loop is one of the most widely used loops in programming. As you begin writing real code, you will find that you will almost always use for loop instead of while loop. Let us now have a look at it. Printing numbers up to 10 We are going to solve the same old problem, let us see how for loop can be used to print numbers from 1 to 10. You know the drill, re-cre
Raspberry Pi is one of the best inventions of our times. We can use this low-cost device to make something really cool and useful. In this article, I will show you how you can control your Raspberry Pi and send instructions to the devices connected to your RPi from anywhere in the world. What is Cloud4RPi? Cloud4RPi is a very simple web control panel for accessing your Raspberry Pi devices. Configuring it takes not more than 2 minutes and you can access your Raspberry Pi anywhere i
Have you ever thought about how some of the World’s biggest companies monitor hundreds of devices? If not, then do it now because, in this tutorial, I am going to introduce you to Nagios. Nagios is a monitoring solution that can monitor a few devices in your house or hundreds of devices, services, network protocols in a multi-billion company. First of all, why do we need Nagios or any monitoring tool at all? It should not be difficult to understand why we need a monitoring tool. A m
MySQL databases handle all the data for websites and apps. Security is of extreme importance when it comes to handling data. So far we have been using the root user for everything. But in real websites, the root user is never used as it has access to all databases. This means that if the root user is compromised, it could result in damage to all databases. So for the security purposes, we should create a new user with password in MySQL. Also Read Import & Export databases
What are the numbers? Are they some physical entity? Some phenomena? No, they are just objects used for measuring a quantity. You must already be aware of the decimal number system that we use. It has the digits from 0-9(0,1,2,3,4,5,6,7,8,9). But this isn’t the only number system use in the computing world. Computers often have requirements different from us human and they may require a different number system. So let us have a look at some of the number systems used in computing.
Hyperspace Drifter is a classic arcade space shooter game. The game features beautiful 3D-like environment settings and cool flat-like spaceship art. It is lightweight too so the game does not require much computing resources unless you are playing it in maximized window mode. Installation Hyperspace Drifter is available on itch.io. itch.io full review is here. Click the Download button and choose the Linux build version to start downloading the game’s zip file package.

Looping is one of the most important core concepts when learning to program. I often see a lot of people get confused with looping. So let us quickly have a look at how loops work. There are various types of loops like the while, do while and for loops. However, we will only focus on the While loop in this article. We will learn about the other loops later in this series. Follow full series – Learn Linux What is a Loop A loop is something that repeats itself. In computer prog
The past few years have seen a hoard of new JavaScript frameworks taking over web development. Skills with Single Page Applications and Progressive Web Apps are the new things that every new developer wants on their resume. Most of the web services are migrating towards Client Side Rendering with JavaScript frameworks. However, Server-side rendering has not lost its charm. What is Server Side Rendering? In modern JavaScript frameworks like angular, react and vue, JavaScript code is
