  • People of WordPress: Collins Agbonghama

    In this series, we share some of the inspiring stories of how WordPress and its global network of contributors can change people’s lives for the better. This month we feature a website builder from Nigeria, who uses the open source WordPress platform to support his family and to share learning with others in his home country and beyond.

    [...]

    A friend at the school had a simple mobile phone which could browse the internet. Collins had his first introduction to the World Wide Web through access to this device. He became hooked by reading headlines on a sports site about a famous English Premier League Football Club, Chelsea, a soccer team which he has long supported.

    “Being a very inquisitive person, I wanted to learn how the web works as well as have my own website. I was able to buy a classic mobile phone through the menial jobs I did after school,” he said.

    His first website was a wapsite or Wireless Application Protocol site optimized for mobile devices.

  • Do-It-Yourself Lexical Pragmas | Tom Wyant [blogs.perl.org]

    The phrase "Lexical Pragmas" is probably both redundant and ungrammatical (the correct plural of "pragma" being "pragmata", I believe). But the use of "pragma" to mean "Perl module with an all-lower-case name" is fairly common, and I wanted to make clear that this was not what I was talking about. This blog entry is about writing Perl code whose configuration changes are limited to a lexical scope, just like built-in pragmata such as strict or warnings.

  • Literate Korn Shell

    This is the first draft of Literate Korn Shell, the unix shell 'ksh' written with all of its innards exposed and explained.

    The goal of Literate Programming is to compile source code into two objects---the executable program with which we are familiar and in additional a document presenting the source code in a format suitable for reading in order to, hopefully, understand it.

    One advantage in particular offered by literate programming is to break up and re-order the code so that its parts can be introduced to the reader in an order and manner which is focussed on the needs of a human reader who may be unfamiliar with the code without the need to bow to the esoteric demands of a compiler.

    This draft of literate ksh has concentrated mostly on this feature, to order the code so that a narrative can be threaded from start to finish which, piece by piece, introduces all of the components which go towards making ksh work.

  • 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.
