  • 10 Excellent Free Books to Learn XML

    XML is a set of rules for defining semantic tags that describe the structure and meaning of a document.

    The user of XML chooses the names and placement of the tags to convey the nature of the data stored in a document. XML can be used to markup any data file to make it easier to understand and process.

    In addition, it has been applied to many special domains of data: mathematics, music, vector graphics, the spoken word, financial data, chemical symbols, and web pages among others.

    Here’s our recommended free books to master XML.

  • A tour with Net::FTP

    When we want to have a way to exchange files between machines, we often think about rsync, scp, git or even something slow and complex (looking at you Artifactory and S3), but the answer is often right in front of your eyes: FTP!

    The “File Transfer Protocol” provides a very simple and convenient way to share files. It’s battle-tested, requires almost no maintenance, and has a simple anonymous access mechanism. It can be integrated with several standard auth methods and even some virtual ones, none of which I show here.

    [...]

    I got the idea to backup and centralize automatically the configuration file during the creation of the build pipeline workspace. It was intended to help both developers (configuration “samples”) and support team (see history, versioned then we can check diffs, file to replay). The constraints were to be able to exchange file from various places with variable users. The FTP protocol is a perfect fit for that.

    I added also a cronjob to autocommit and push to a git repository and we had magically a website listing versioned configurations files.

    In addition, FTP proved later to also require zero support. I mean really zero maintenance!

  • Perl Mongers, Unite!

    pm.org is great for resources, but there's no obvious way to promote your meeting. Not that there needed to be when the meetings were local events, but now, thanks to Covid-19, these meetings are taking place virtually. Why limit yourself to your local members? I am convinced that there are plenty of pockets of mongers that, if united and connected, would make the world realize that Perl Is Not Dead.

  • Programming languages: Now Rust project looks for a way into the Linux kernel

    The makers of systems programming language Rust are looking at how to adapt the language for use in the Linux kernel.

    Josh Triplett, an Intel engineer and lead of the Rust language project, says he'd "love to see a path to incorporating Rust into the kernel", as long as it's done cautiously and doesn't upset Linux kernel creator Linus Torvalds.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
