  • The pygame project has finally ready

    It has been a day since I had mentioned that I want to upload the new pygame project to the major gaming websites but because of some technical problems that occurred during the files packaging stage the uploading plan has been delayed until today. I have managed to solve all the files packaging issues this morning thus finally this game has been uploaded successfully to various gaming websites. Although we have finished this project together this game is still at its early stage which means more features and levels will be included from time to time. You can download this game from any of these three websites below.

  • Creating your own custom terminal image

    In this series of posts I have been talking about some of the work I have been doing with creating environments to host workshops when needing to train users in using a software product such as OpenShift.

    In the first post I explained how JupyterHub can be used to deploy web applications other than Jupyter notebooks, and how I use it to deploy user environments which give each attendee of a workshop, access to an interactive command line shell in their browser, with all the command line client tools and files they need for the workshop.

    In the second post I delved into how the container image was constructed, as well as how it could be run independent of using JupyterHub where a user may want to deploy it themselves and wasn't running a workshop.

    In this post I am going to explain more about how the terminal image is constructed and how it can be extended to add additional command line tools and files required for a specific workshop.

  • 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.
