  • Unleashing Accelerated Speeds with RAM Drives

    Time is money, and sometimes that means you need a faster way to process data. Solid state drives (SSDs) and, more specifically, non-volatile memory express (NVMe) devices have helped alleviate the burden of processing data to and from a backing store. However, at times, even SSD technology is not quite fast enough, which is where the RAM drive comes into the picture.

    Typically, the RAM drive is used as temporary storage for two reasons: Its capacities tend to be lower (because the technology is more expensive), and more importantly, it is a volatile technology; that is, if the system were to lose power or go into an unstable state, the contents of that RAM drive would disappear. Depending on the type of data being processed, the reward can often outweigh the risks, which is why the RAM drive can potentially be the better option.

    In this article, I rely on the RapidDisk suite to create and manage RAM drives. The RapidDisk software project [1] provides an advanced set of Linux kernel RAM drive and caching modules with which you can dynamically create and remove RAM drives of any size or map them as a temporary read cache to slower devices.

    The system used in this article is an older system with limited memory clocked at a slow speed. More modern and faster systems with faster memory will produce significantly different results than those found here. The dmidecode command summarizes the configuration and capabilities of memory DIMMs and revealed that my system has four DDR3 RAM devices of 2048MB configured at speeds of 1333MTps (mega transfers per second).

  • How does Oracle VM Virtualbox work?

    VirtualBox is a general-purpose virtualization program for x86 and x86-64 hardware that lets users and administrators run several guests operating systems on a single host. It intendes for the server, desktop, and embedded applications
    VirtualBox is a graphical user interface (GUI) and command-line program for virtualizing servers, desktops, and embedded operating systems. A single VirtualBox host may run as many guest virtual machines as the host hardware allows.

    VirtualBox has two types of users: hosts and guests. The host is where the VirtualBox software is kept, from whence the guests may be deployed. Any compatible operating system running as a virtual machine is referred to as a guest. VirtualBox hosts can run Linux, Windows, or macOS, while guests may run any Linux distribution, Solaris, macOS, BSD, IBM OS/2, or Windows. To run macOS or Windows as a virtual machine, you’ll need a licensed copy of the operating system.

    Administrators can deploy hosts using ISO images or VDI/VMDK/VHD images when using VirtualBox as the host platform. When guests are deployed from an ISO image, the guest operating system is installed normally, but only as a virtual machine. It is possible to quickly deploy a virtual appliance using VDI/VMDK/VHD images without having to go through the procedures of installing the operating system as the guest. TurnKey Linux is an excellent source to get virtual appliances for VirtualBox.

    The VirtualBox Extension Pack adds support for USB 2.0 and USB 3.0 devices, VirtualBox RDP, disc encryption, NVMe, and PXE boot for Intel GPUs to make VirtualBox even more desirable. The Guest Additions adds mouse pointer integration, shared folders (between guest and host), better video support, seamless windows, generic host/guest communication channels, time synchronization, shared clipboard, and automatic logins to the VirtualBox feature set.

  • 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.
