    It can simulate a cloud environment with the support of cloud-init. It helps to create a new development or testing environment with ease. It also supports VirtualBox on macOS & Linux also. In this tutorial, we will learn how to install Multipass on Ubuntu

  • How to install Java on Manjaro Linux

    Many developers and programmers choose Manjaro because it's one of the most user-friendly and feature-rich Linux distributions. In this guide, we go over the steps to install the Java Development Kit on Manjaro Linux. We'll show you how to install both the OpenJDK package (which is free and GPL-licensed) as well as Oracle Java SE Development Kit.

    Arch Linux and Manjaro only officially support the OpenJDK, as that is the non-proprietary version. However, the Oracle package can be installed from the AUR, as you'll see shortly.

  • Lenovo ThinkPad Booting GNU/Linux USB

    Lenovo ThinkPad users can boot USB drives finely. As Ubuntu Buzz often publishes booting articles, now let's learn how to practice that on computers using ThinkPad as example. By making this tutorial I hope I give abilities to all computer users who didn't know yet they can do this amazing thing. Let's go!

  • How to install Arduino IDE on CentOS 8

    Arduino IDE stands for the “Arduino Integrated Development Environment”. Arduino is used to create electronic devices that communicate with their environment using actuators and sensors. Arduino IDE contains an editor that is used for writing and uploading programs to the Arduino board. Before start to create projects through Arduino, the user needs to set up an IDE for the programmable board.

    In this article, we will learn how to install the latest Arduino IDE on CentOS 8.

  • Vincent Fourmond: QSoas tips and tricks: generating smooth curves from a fit

    Often, one would want to generate smooth data from a fit over a small number of data points. For an example, take the data in the following file. It contains (fake) experimental data points that obey to Michaelis-Menten kinetics: $$v = \frac{v_m}{1 + K_m/s}$$ in which \(v\) is the measured rate (the y values of the data), \(s\) the concentration of substrate (the x values of the data), \(v_m\) the maximal rate and \(K_m\) the Michaelis constant.

    [...]

    Now, with the fit, we have reasonable values for \(v_m\) (vm) and \(K_m\) (km). But, for publication, one would want to generate "smooth" curve going through the lines... Saving the curve from "Data.../Save all" doesn't help, since the data has as many points as the original data and looks very "jaggy" (like on the screenshot above)... So one needs a curve with more data points.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
