  • Excellent Free Tutorials to Learn Less - LinuxLinks

    Less (stands for Leaner Style Sheets) is a backwards-compatible language extension for Cascading Style Sheets (CSS). This dynamic preprocessor style sheet language can be compiled into CSS and run on the client side or server side.

    Less provides the following mechanisms: variables, nesting, mixins, operators and functions; the main difference between Less and other CSS precompilers is that Less allows real-time compilation via less.js by the browser.

    Because Less looks just like CSS, learning it is easy. Less only makes a few convenient additions to the CSS language, which is one of the reasons it can be learned so quickly.

  • US, EU cyber investments in Ukraine pay off amid war [iophk: Windows TCO]

    The West began actively investing in Ukraine’s cyber defenses following the 2015 power grid hack and the 2017 Petya malware attack.

  • Drop View If Exists postgres

    As the name suggests, a view can be a glance at a database record from a different site. A view in PostgreSQL is a subset of one or more tables to see the important data. We mostly create views to execute the most-used query in the database. Those, who don’t have any understanding of Database views, will get some knowledge today. Therefore, we will be discussing a method to create, use and drop the views in the PostgreSQL database.

  • How to Use postgres Xpath

    You may have worked on Html, XML, and CSS while learning web designing. XML is said to be an extensible markup language that contains user-defined tags without already defined tags as the “Html” language has. While working in the PostgreSQL database, there come situations when you have to save the XML type data in your tables. Most of the students get confused about fetching such sort of data from the PostgreSQL database tables. Therefore, the PostgreSQL database provides us with the “XPath” function to fetch and modify the XML type data columns. Thus, this article will contain an explanation of using the Xpath function in the PostgreSQL database. Let’s initiate and make sure to not skip any step.

  • 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.
