The Wine AppDB is a database containing a list of applications that have been tested and confirmed to work under Wine.

  • Monitoring for process completion in 2021 – Ariadne's Space

    A historical defect in the ifupdown suite has been the lack of proper supervision of processes run by the system in order to bring up and down interfaces. Specifically, it is possible in historical ifupdown for a process to hang forever, at which point the system will fail to finish configuring interfaces. As interface configuration is part of the boot process, this means that the boot process can potentially hang forever and fail to complete. Accordingly, we have introduced correct supervision of processes run by ifupdown-ng in the upcoming version 0.12, with a 5 minute timeout.

    Because ifupdown-ng is intended to be portable, we had to implement two versions of the process completion monitoring routine. The portable version is a busy loop, which sleeps for 50 milliseconds between iteration, and the non-portable version uses Linux processor descriptors, a feature introduced in Linux 5.3. For earlier versions, ifupdown-ng will downgrade to using the portable implementation. There are also a couple of other ways that one can monitor for process completion using notifications, but they were not appropriate for the ifupdown-ng design.

  • How to Install Let's Encrypt SSL for NGINX on Rocky Linux 8

    Security is one of the top-of-mind concerns for website owners, more especially, if you are running an eCommerce store or a site that accepts users’ confidential information such as usernames and passwords. The plain HTTP protocol is insecure as data is sent in plain text and hackers can eavesdrop on the communication sent to and from the web server.

    To overcome this risk, it’s recommended to secure a web server using a TLS/SSL certificate. This is a cryptographic digital certificate that encrypts your web server and ensures data exchanged with the webserver is encrypted.

    Let’s Encrypt SSL certificate is a digital certificate provided by Let’s Encrypt CA ( Certificate Authority) to secure a web server. It’s a free TLS/SSL certificate that is valid for only 90 days, whereupon renewal is required before expiry. It’s beneficial for startups or individuals who cannot afford a premium SSL certificate for their blogs or websites.

    In this guide, we will demonstrate how you can install the Let’s Encrypt SSL/TLS certificate for NGINX on Rocky Linux 8

  • Watch Logs in Real Time in Linux With Tail, Less & Multitail

  • 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.
