  • How to Compile & Install Python 3.10.0 from Source in Ubuntu 21.04, 21.10 | UbuntuHandbook

    This simple tutorial shows how to compile and install Python 3.10.0 or other certain Python version in Ubuntu.

    For Ubuntu 18.04 and Ubuntu 20.04 LTS, there’s well trusted “deadsnakes” team PPA that maintains all the Python packages. For non-LTS releases, e.g., Ubuntu 21.04 and Ubuntu 21.10, you may build the programming language package manually from the source tarball.

    NOTE: Ubuntu 21.04 has Python 3.10 beta1 in universe repository, remove it if installed before doing the steps below. For Ubuntu 21.10, Python 3.10 will be soon made into the universe repository, so you may skip or install a certain version (e.g., 3.8 or 3.7) via this tutorial.

  • How to make snaps faster | Ubuntu

    A great user experience is (or at least, should be) an integral part of any software that involves user interaction. On the desktop, this starts with the application launch, and continues through the session. The overall time to completion of tasks as well as interactive responsiveness are a core element in this journey.

    If you’re a snap developer or publisher, the topic of speed may arise for various reasons. The differences in the overall architecture and principles of operation of snaps, in comparison to software deployed as Deb or RPM packages, can sometimes lead to a slower experience. This goes against the prime directive of desktop usage. In this article, we want to show you a number of methods and tools you can use to make your snaps snappy.

  • Ian's TechBlog: Installing Ubuntu Core onto 64-bit Bare Metal

    I have a re-purposed AMD64 laptop motherboard, ready to become an experimental Ubuntu Core server.

    It's in fine condition. You can see that it boots an Ubuntu LiveUSB's "Try Ubuntu" environment just fine. Attached to the motherboard is a new 60GB SSD for testing. The real server will use a 1TB HDD.

    But Ubuntu Core doesn't install on bare metal from a Live USB. It's still easy, though.

  • Using Salsa with contrib and non-free - linux.codehelp.co.uk

    OK, I know contrib and non-free aren't popular topics to many but I've had to sort out some simple CI for such contributions and I thought it best to document how to get it working. You will need access to the GitLab Settings for the project in Salsa - or ask someone to add some CI/CD variables on your behalf. (If CI isn't running at all, the settings will need to be modified to enable debian/salsa-ci.yml first, in the same way as packages in main).

  • List, Upload and Download files from an SFTP Server using golang

    In this guide we are going to explore how to use Golang script to do operations on an SFTP server.

    SFTP (Secure File Transfer Protocol) is a file transfer protocol that leverages a set of utilities that provide secure access to a remote computer to deliver secure communications. It relies on SSH.

  • How to use this unique method of securing SSH - TechRepublic

    The other day I was thinking of ways to secure SSH that were a bit outside the norm. Let's face it, we've all configured SSH in /etc/ssh/sshd_config and /etc/ssh/ssh_config. We've blocked root login, we've set SSH to a non-standard port, we've installed fail2ban, and we've enabled SSH key authentication. What more can we do?

  • MySQL date format – what you need to know | FOSS Linux

    MySQL is derived from ‘My’- the cofounder’s daughter and SQL- Structured Query Language. It is an open-source type of relational database management system. This relational database system helps organize data into relatable tables, thereby enabling structural relations of different data sets.

    MySQL date is one of the temporal data types that can manage data values alongside other data types such as numeric data types, String data types, Boolean data types, date and time, and spatial data types.

    The DATE_FORMAT() function is used in MySQL to format date using the specified format value. For instance, if a date is provided, the function will format it concerning the specified parameters.

  • snap Vs .deb Package

    As the number of Linux applications grows, so does the concern about security. Even though there are few recorded Linux attack incidents, it is conceivable to be attacked by viruses, hackers, or malware.

    Because Linux is open-source, those problems are fixed faster, and the community may contribute to maintaining the Linux World ready for any bug or virus that appears. When installing a vulnerable application (or app), it may require libraries that are no longer accessible on that distro’s version.
    In this article, we’ll go through the key distinctions between.deb and.snap packages.

  • [Fixed] error: snap “package” not found

    Snap has grown in popularity among Linux users. Instead of using system packages, snap containerizes their dependencies. Each snap app is unaffected by whether or not a certain package is present on the system.

    Snap applications are simple to design and distribute for a variety of Linux distributions. Because snap programs package their dependencies in a bundle, they may be installed on any Linux distribution that supports snaps. Snap applications are an excellent way for novice Linux users to get past the learning curve.

    Snaps, like any other package manager, has simple commands for installing, removing, and updating snap packages. Make sure your distribution has snap installed and configured before installing a snap application. If not, use your distribution’s package manager to install snapd.

  • 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.
