  • How To Install Python 3.9 on Linux Mint 20 - idroot

    In this tutorial, we will show you how to install Python 3.9 on Linux Mint 20. For those of you who didn’t know, Python is a very powerful high-level programming language that has seen extensive adoption in modern application development. Python programs are remarkably easy to write when compared to other programming languages. Linux Mint 10 default repositories come with Python 3.7. Recently, Python 3.9 is released, introducing many updates.

    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 through the step-by-step installation of Python 3.9 on a Linux Mint 20 (Ulyana).

  • Use fdisk Format Partition – Linux Hint

    For managing disk partitions, fdisk is a command-line partition editor. It can create, edit, delete, and format almost any partition. It supports all the major partition tables, including GPT, MBR, Sun, SGI, and BSD. It makes fdisk compatible with almost all the standard partition formats.
    In this guide, check out how to use fdisk to format a partition.

  • Rethinking RAID (on Linux)

    Often, you find yourself attempting to eke out a bit more performance from the computer system you are attempting either to build or recycle, usually with limited funds at your disposal. Sure, you can tamper with the CPU or even memory settings, but if the I/O hitting the system needs to touch the underlying storage devices, those CPU tunings will make little to no difference.

    In previous articles, I have shared methods by which one can boost write and read performance to slower disk devices by leveraging both solid state drives (SSD) and dynamic random access memory (DRAM) as a cache. This time, I will instead shift focus to a unique way you can configure redundant storage arrays so that you not only boost overall data access throughput but also maintain fault tolerance. The following examples center around a multiple-device redundant array of inexpensive (or independent) disks (MD RAID) in Linux and its userland utility mdadm.

    Conventional wisdom has always dictated that spreading I/O load across more disk drives instead of bottlenecking a single drive does help significantly when increasing one's workload. For instance, if instead of writing to a single disk drive you split the I/O requests and write that same amount of data in a stripe across multiple drives (e.g., RAID0), you are reducing the amount of work that a single drive must perform to accomplish the same task. For magnetic spinning disks (i.e., hard disk drives, HDDs), the advantages should be more noticeable. The time it takes to seek across a medium introduces latency, and with randomly accessed I/O patterns, the I/O throughput suffers as a result on a single drive. A striped approach does not solve all the problems, but it does help a bit.

  • 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.
