  • Signal Desktop on OpenBSD via vmm(4)

    Early this year, I completely switched over to Signal and I’m fortunate enough to have everyone that I talk to switch over as well. I know I wrote what some might view as a hit piece on Signal, but I have immense respect for the project and will continue to use it until an actually viable alternative comes along.

    Unfortunately, their desktop application isn’t natively available for OpenBSD. A solution that’s worked decently enough for me is to run it via X11 forwarding on a Ubuntu VM running on vmm(4) — OpenBSD’s built-in hypervisor.

  • I did not realize I was an OpenBSD user!

    For multi-room audio, I set up a proof of concept with some old computers and configured mpd to use sndio. It worked great. I purchased several more APU2D4 machines and USB Behringer UCA202 DACs for the audio. I created C++ microservices to run with httpd slowcgi and build / send mpc commands to control mpd. Simple, no library dependencies and easy to update / test. Maybe someday I'll change the interface but this has been working well. For UI, I created a page to select a room and send commands. Wanting a single volume control, I opted to expose master volume (rather than mpd volume). I needed to select music, so I created another page to access music data. I'm only really interested in playlists, artists, genres and songs, so I provided these in the song UI and allow adding to the queue of whatever room is currently selected. Each room can operate independently or output to multiple rooms.

  • 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.
