  • Deployd: The REST-API toolkit is not active anymore.

    Deployd is a free, open-source platform for quickly building a REST-API on top of MongoDB.

    It is an easy-to-use system, as the user does not require any boilerplate, and dive directly into a user-friendly dashboard and start creating and testing your DB collections and API.

    Deployd comes with dozens of useful features which speeds up the production time. Moreover, it comes with a set of examples, guides, and a developer-friendly rich documentation.

  • Using the regexp-parser of syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    For many years, you could use the match() filter of syslog-ng to parse log messages with regular expressions. However, the primary function of match() is filtering. Recent syslog-ng versions now have a dedicated regular expression parser, the regexp-parser(). So, you should use match() only if your primary use case is filtering. Otherwise, use the regexp-parser for parsing, as it is a lot more flexible.

  • Automating my home network with Salt - Federico's Blog

    In my mind there exists this whole universe of scary power tools for large-scale sysadmin work. Of course you would want some automation if you have a server farm to manage. Of course nobody would do this by hand if you had 3000 workstations somewhere. But for my puny home network with one server and two computers? Surely those tools are overkill?

    Thankfully that is not so!

    My colleague Richard Brown has been talking about the Salt Project for a few years. It is similar to tools for provisioning and configuration management like Ansible or Puppet.

    What I have liked about Salt so far is that the documentation is very good, and it has let me translate my little setup into its configuration language while learning some good practices along the way.

    I started with the Salt walkthrough, which is pretty nice.

    TL;DR: the salt-master is the central box that keeps and distributes configuration to other machines, and those machines are called salt-minions. You write some mostly-declarative YAML in the salt-master, and propagate that configuration to the minions. Salt knows how to "create a user" or "install a package" or "restart a service when a config file changes" without you having to use distro-specific commands.

  • Visual-inertial tracking for Monado

    Monado now has initial support for 6DoF ("inside-out") tracking for devices with cameras and an IMU. Three free and open source SLAM/VIO solutions were integrated and adapted to work on XR: Kimera-VIO, ORB-SLAM3, and Basalt. Thanks to this, the RealSense and WinMR (Linux only) drivers in Monado were extended to support this type of tracking.

    During my six-month internship at Collabora, I had the opportunity to gain firsthand experience on this project. Let me walk you through the concepts, the type of work, and exposure I attained while working remotely as an intern in the XR team for Monado. If any of this has piqued your interest, be sure to check out our careers page.

  • Launch Your First Jenkins Server in a Single Command | by Vladimir Mukhin | Apr, 2022 | Medium

    Jenkins is one of the oldest and most popular CI/CD tools. It dominates the market and is a requirement for more than 50% of job positions. However, Jenkins is a complicated solution, installing it requires a lot of heavy lifting and can become a pain. In this article, I will uncover the fastest way to deploy Jenkins using only one command.

  • How to write a Python script to create dynamic Ansible inventories | Enable Sysadmin

    In my last article, I used the host_list and Nmap plugins to generate a dynamic inventory to cover that gap. This article covers how to write your own dynamic inventory script using Python while following good practices for packaging tools, using virtual environments, and unit testing your code.

Open source XR runtime Monado adds initial 6DoF 'inside-out'...

  • Open source XR runtime Monado adds initial 6DoF 'inside-out' tracking support

    It's been a little while since we heard progress on Monado, the free and open source XR (VR / AR) runtime for Linux but it has been progressing nicely with a big new feature added. Developer Mateo de Mayo had a six-month internship at Collabora, and decided to do a write up on this exciting enhancement for Monado.

    Pretty tech-heavy stuff here, and not something for regular consumers to read through and think "ah yes, I understood all that". The basic gist is that Monado, on Linux, can now support XR devices that have cameras and an IMU (Inertial measurement unit) to provide 6DoF (inside-out) tracking utilizing other open source projects like Kimera-VIO, ORB-SLAM3, and Basalt.

Monado accepted in GSoC 2022!

  • Monado accepted in GSoC 2022!

    We're proud to announce that Monado, the free and open source XR platform, has been accepted for the first time as a mentoring organization for the 2002 Google Summer of Code (GSoC)! Collabora will be providing three mentors to support contributors who want to work on Monado-related projects.

    For 17 years, GSoC has focused on bringing new open source contributors into open source communities. GSoC has brought over 18,000 university students from 112 countries together with over 17,000 mentors from 746 open source organizations! Head to their website to learn more.

    Beginning in 2022, GSoC is opening the program up to all newcomers of open source that are 18 years and older. The program will no longer focus solely on university students or recent graduates! If you're new to open source and want to learn more about Monado OpenXR runtime, check out the Monado webpage on freedesktop and our 2022 GSoC Project Ideas here to get you inspired. Then join GSoC to submit your proposal, and if accepted, you'll get a mentor from Collabora to guide you on your journey!

  • 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.
