  • Executive Viewpoint 2019 Prediction: IGEL – Linux Will Power Virtualization Growth

    The rapid adoption of the Internet of Things (IoT), continued transition of workloads to the cloud, and the enterprises’ ever-increasing pressure to protect data in a connected world are three key happenings that will drive the growth use of Linux in 2019 and beyond.

    There are an estimated six billion IoT devices in use today, and the vast majority of these devices are running a Linux kernel. If analyst estimates are correct, the number of IoT devices will increase exponentially over the next few years, and all of these devices will be communicating with virtualized data collectors. According to Gartner, there will be 20.4 billion connected devices by 2020. Most of these will be running a Linux kernel.

  • What is QEMU in Linux?

    QEMU is free and open source (FOSS) hardware virtualization toll developed by Fabrice Bellard distributed under GPL license. It supports a wide range of operating systems including Windows and MacOS. Bochs, PearPC, etc. are similar, but do not have many of its features, such as high-speed and cross-platform features. It is like VirtualBox and VMware virtualization software but natively it is command based tool unlike the two mentioned. To get the near-native speed of hardware in a virtualization environment one can use it with the KVM with the help of hardware extensions such as Intel VT-x.

    qemu of 0.9.1 and earlier can use the kqemu accelerator. In the version after qemu1.0, kqemu cannot be used , mainly using the qemu- kvm acceleration module, and the acceleration effect and stability are significantly better than kqemu.

  • Best Free Virtualbox Alternative for Linux

    Hundreds of different Linux distros are around over the internet and we cannot install all of them our PC for testing or learning purposes. However, one thing we can do is to run them on Linux as virtual machines to experience before actually switch to a new Linux Distro.

    For Windows, there are lots of Virtualization software available those let you install almost any kind of operating system virtually but what about Linux the users? When we talk about Virtualization on Linux, Windows or MacOS, the first Virtual Machine creating software comes in our mind is Oracle’s VirtualBox. This virtualization solution is also open source and free to use but wait, does any other solution or software is available, especially for the Linux operating system. As I said, Windows and MacOS have a couple of good Virtualization options available but all these solutions are not available for Linux distros because of their sundry nature.

  • 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.
