  • 5 key insights for open source project sustainability in 2022 |

    Many technology firms are turning to open source tools to accelerate innovation and growth. As these firms work to influence open source projects, governance practices sometimes shift from coordination among a small group of developers and firms to management by large communities of contributors and organizations, often with competing priorities.

    Sustainable projects require sustainable communities. Adapting to a larger, more competitive open source landscape requires organizations to invest in community building. This demands a view of source-code availability that's inextricably connected to the social engagements of contributors and organizations in open source projects. Many organizations now consider open source community engagement as both a social and a technical—or "sociotechnical"—investment.

  • Navigating repositories with myrepos-utils :: Pensées de Michel — Personal thoughts and musings

    I’ve been using myrepos for a while - as someone who juggles a lot of repositories, both for personal projects and as a Fedora and CentOS packager, a ~/.mrconfig synced via Nextcloud really makes checking out repositories consistently, on different computers, straightforward.

    As the number of tracked repos grow, however, trying to remember where each repo is checked out gets a bit time consuming – and also, keeping the configuration file organized as well; mr register on an existing repo would add the entry for that repo at the end of the file, and I was previously resorting to editing the file by hand to get it sorted - with a varying degree of success.

  • Develop a basic rate limiter with Quarkus and Redis | Red Hat Developer

    Rate limiting is a popular technique to protect services from excessive demand. For example, you can use this strategy to limit how often a user can enter or reset their password. The example in this article builds rate limiting on a per-client basis into a Java-based service for a given time period. The application tracks requests from clients using a Redis in-memory data structure store and limits usage when a client's demand exceeds the quota.

  • 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.
