  • Advance!BSD – thoughts on a not-for-profit project to support *BSD (1/2)

    There are multiple reasons why I am a BSD user and enthusiast. For one thing I enjoy using systems where the design benefits from the holistic approach (whole OS vs. “kernel + some packages”). I’ve come to appreciate things like good documentation, preference of simplicity over unnecessary complexity and permissive licensing. There’s a different spirit to the community that makes me feel more at home. Well, and truth be told: I do have a heart for “outsiders” who are doing well but get far less attention due to the towering popularity of a certain other system. In addition to that I’m very much concerned about the new de-facto monopoly in open source.

  • Advance!BSD – thoughts on a not-for-profit project to support *BSD (2/2)

    Another general question is what makes more sense to focus on: Some form of virtualization (either full-fledged VMs or paravirtualization like FreeBSD’s jails either with or without VNET) or rather providing shared services? There certainly is a need for both. And while I’m certain that the vast majority of BSD people would be perfectly capable of renting a VM and doing all the things they need themselves, I’m not sure if everybody wants to.

  • WSO2 Choreo - Delivering a Platform for Innovation

  • What Every Programmer Should Know About SSDs

    SSDs have become quite cheap and they have very high performance. For example, a Samsung PM1733 server SSD costs about 200 EUR per TB and promises close to 7 GB/s read and 4 GB/s write bandwidth. Actually achieving such high performance requires knowing how SSD work and this post described the most important behind-the-scenes mechanisms of flash SSDs.

  • Licenses Alone Do Not Govern Behavior in Open Source

    That difference rests in the fact that design and distribution of software is collapsed into a single step - just post it to the repo. In hardware those steps are quite distinct. Designing open source hardware is quite separate from distributing actual pieces of hardware. That may make it harder for a single person to be responsible for maintaining a piece that is incorporated into millions of projects without any sort of support. But that’s another blog post for another day. Even if the dynamic is not identical, it is certainly similar enough to think about and try to avoid in open hardware.

  • Use F-Droid to Install Open Source Android Apps

    When it comes to Android apps, most people will think of the Google Play store where they download or purchase apps. Most of the time, those apps you download are closed source and controlled by developers. If you have a passion for free and open-source (FOSS) software, F-Droid is a marketplace for you to find all the FOSS Android apps.

    F-Droid is an application run by Droid Ltd. It was founded by Ciaran E Gultnieks, a British computer programmer, back in 2010. Since then, the app has hosted over 4000 free and open-source applications. The applications come in a wide variety, including health, education, security, and more. Let us dive into how to install F-Droid and use it to install free and open-source Android apps.

  • 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.
