  • WebKitGTK 2.23.90 Adds Support For JPEG2000, More Touchpad Gestures

    It missed the GNOME 3.32 Beta by a week, but out today is the WebKitGTK 2.23.90 release, the downstream of the WebKit web layout engine focused on GTK integration and used by the likes of GNOME Web (Epiphany).

    Interestingly, this WebKitGTK release adds support for JPEG2000. That support is a bit surprising considering outside of Apple's Safari browsers, JPEG2000 isn't really supported by other web browsers for this offshoot of JPEG that has never been widely adopted. But now nearly two decades after JPEG2000 was published, it's at least supported by WebKitGTK.

  • Python 3.8 alpha in Fedora
  • Fedora 31 Is Already Planning Ahead For Python 3.8

    While Fedora 30 isn't debuting for another three months, with the system-wide change deadline already having passed on that release, ambitious Fedora developers are already thinking about early feature plans for Fedora 31 that will debut in November.

    One of the first Fedora 31 system-wide change proposals is for upgrading from Python 3.7 to Python 3.8. Python 3.7 was released just last summer and the Python 3.8.0 release isn't even expected until the end of October, but given it will be another big update to Python3, Fedora developers are working on coordinating the upgrade early to prevent possible fallout late in the cycle.

  • What You Don't Know About Python Variables

    The first time you get introduced to Python’s variable, it is usually defined as “parts of your computer’s memory where you store some information.” Some define it as a “storage placeholder for texts and numbers.” We will soon find out that Python’s variable is deeper than this.

  • 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.
