The Free Software Movement aims to spread awareness of this issue and to advocate for the use of freedom-respecting software ("free software").

  • Participate in Hacktoberfest, Help Develop Contributions

    The month-long, virtual-festival event that celebrates open source contributions, Hacktoberfest, is coming soon and members of the openSUSE community can make a difference.

    The event that is in its seventh year and run by Digital Ocean and DEV encourages people to make their first contributions to open source projects.

    The event is for developers, designers who contribute artwork, people who can contribute to documentation,and more.

    As the event brings more awareness to open-source projects and encourages contributions that benefit communities, having developers and community members available to help people who want to contribute can be beneficial to the project.

  • Are universities spending enough on cybersecurity? [iophk: Windows TCO]

    Such attacks “will absolutely continue”, said Mark Ford, who leads higher education risk and financial advisory services for the audit firm Deloitte. As higher education becomes known as an “easy target”, this increasingly “attracts the bad guys”, he explained.

    The threat comes not just from criminals seeking money. Universities now house arguably the most valuable secrets on earth – plans for a coronavirus vaccine – putting them in the sights of state-backed [cr]ackers. In July, UK, US and Canadian intelligence services warned that Russian groups were attempting to target Covid-19 vaccine research and development.

    This raises the question: are universities doing enough to defend themselves against [cr]acking?

    The additional integration of the SLURM workload manager, an open-source job scheduler for Linux and Unix-like kernels, means that vScaler Cloud users can request traditional resources like memory and compute cores to be available for jobs.

  • Profiling slow-running queries in Amazon DocumentDB (with MongoDB compatibility)

    Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. You can use the same MongoDB 3.6 application code, drivers, and tools to run, manage, and scale workloads on Amazon DocumentDB without having to worry about managing the underlying infrastructure. As a document database, Amazon DocumentDB makes it easy to store, query, and index JSON data.

    AWS built Amazon DocumentDB to uniquely solve your challenges around availability, performance, reliability, durability, scalability, backup, and more. In doing so, we built several tools, like the profiler, to help you run analyze your workload on Amazon DocumentDB. The profiler gives you the ability to log the time and details of slow-running operations on your cluster. In this post, we show you how to use the profiler in Amazon DocumentDB to analyze slow-running queries to identify bottlenecks and improve individual query performance and overall cluster performance.

  • 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.
