  • A Guide to Zsh Expansion with Examples

    Zsh is particularly powerful when you need some good old expansions. It supports common ones used by Bash too, and add many flags and modifiers on top. It comes in handy to manipulate quickly your commands without writing boring shell scripts.

    We’ll see, in this article, what we can do with Zsh expansions, and more specifically:

    How to use glob operators and globbing flags.

    What glob qualifiers we can use to expand filenames.

    How to expand the Zsh history and how to modify these expansions.

    How to expand parameters, using modifiers and flags.

  • glibc is still not Y2038 compliant by default – Ariadne's Space

    Most of my readers are probably aware of the Y2038 issue by now. If not, it refers to 3:14:07 UTC on January 19, 2038, when 32-bit time_t will overflow. The Linux kernel has internally switched to 64-bit timekeeping several years ago, and Alpine made the jump to 64-bit time_t with the release of Alpine 3.13.

    In the GNU/Linux world, the GNU libc started to support 64-bit time_t in version 2.34. Unfortunately for the rest of us, the approach they have used to support 64-bit time_t is technically deficient, following in the footsteps of other never-fully-completed transitions.

  • 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.
