  • Linux Fu: Walk, Chew Gum | Hackaday

    If you ever think about it, computers are exceedingly stupid. Even the most powerful CPU can’t do very much. However, it can do what it does very rapidly and repeatably. Computers are so fast, they can appear to do a lot of things at once, too and modern computers have multiple CPUs to further enhance their multitasking abilities. However, we often don’t write programs or shell scripts to take advantage of this. However, there’s no reason for this, as you’ll see.

  • Writing Absinthe authorization middleware

    Plug is not the only interface with the middleware layer. Absinthe also comes with a middleware layer of its own and we can use it similarly to implement authorization for queries, mutations, and subscriptions.

    If we want to authorize our GraphQL API and don’t want to do that within business logic (for various reasons), we can write a middleware that will handle it. I wrote about using Plug for authorization, but using a plain Plug wouldn’t work in this case.

    Since GraphQL is essentially a graph, we need to cover authorization for all nested queries. Absinthe middleware can do that for us, and might also be used for specific query fields, which is quite handy.

  • Edit sshd_config using a Bash script | Enable Sysadmin

    Using a Bash script, you can ensure certain configuration parameters are set in your sshd_config file.

    Bash is the default shell on most Linux systems these days. It can be used as an interactive command-line interpreter as well as a scripting language to automate common tasks. This article shows you how to use a Bash script to ensure specific configuration parameters are set in your /etc/ssh/sshd_config file.

  • Add A News Ticker To Your Desktop With TICKR (Scrolling News Feed Widget) - Linux Uprising Blog

    TICKR is a news ticker desktop widget - a feed reader that displays news headlines as a small scrolling text line (ticker) on your desktop, available for Linux and Microsoft Windows.

    Add your favorite website RSS feeds to TICKR, and the tool will show the latest headlines scrolling in a thin, semi-transparent window similar to those available on news TV channels. Hovering the mouse over the ticker pauses the scrolling, while pointing the mouse to a headline shows an excerpt of the article in a tooltip. Left-click the headline in TICKR to open it in your web browser.

    This scrolling news desktop widget comes with the ability to import and export feeds (OPML), as well as a GUI to manage your RSS feeds, which includes some popular RSS feeds, and allows you to add, remove, re-arrange, enable or disable feeds.

  • 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.
