  • CMS: Is a Self-hosted Open-source Contest Management System

    CMS, or Contest Management System, is a distributed system for running and (to some extent) organizing a programming contest.

    CMS has been designed to be general and to handle many types of contests, tasks, scoring, etc. Nonetheless, CMS has been explicitly built to be used in the 2012 International Olympiad in Informatics, held in September 2012 in Italy.

  • OSSummit North America is going to be weird – and I can’t wait

    Of course it will: first, it’s in Austin, self-proclaimed capital of weird since 2003. Second, it’s a large in-person event after so many years of pandemic, during a massive heat wave, an economic crash, wildfires, drought and floods and a war.

  • Petter Reinholdtsen: My free software activity of late (2022)

    I guess it is time to bring some light on the various free software and open culture activities and projects I have worked on or been involved in the last year and a half.

    First, lets mention the book releases I managed to publish. The Cory Doctorow book "Hvordan knuse overvåkningskapitalismen" argue that it is not the magic machine learning of the big technology companies that causes the surveillance capitalism to thrive, it is the lack of trust busting to enforce existing anti-monopoly laws. I also published a family of dictionaries for machinists, one sorted on the English words, one sorted on the Norwegian and the last sorted on the North Sámi words. A bit on the back burner but not forgotten is the Debian Administrators Handbook, where a new edition is being worked on. I have not spent as much time as I want to help bring it to completion, but hope I will get more spare time to look at it before the end of the year.

    With my Debian had I have spent time on several projects, both updating existing packages, helping to bring in new packages and working with upstream projects to try to get them ready to go into Debian. The list is rather long, and I will only mention my own isenkram, openmotor, vlc bittorrent plugin, xprintidle, norwegian letter style for latex, bs1770gain, and recordmydesktop. In addition to these I have sponsored several packages into Debian, like audmes.

  • Update on OpenType MATH fonts - Frédéric Wang

    I mentioned in a previous post that Igalia organized the Web Engines Hackfest 2022 last week. As usual, fonts were one of the topic discussed. Dominik Röttsches presented COLRv1 color vector fonts in Chrome and OSS (transcript) and we also settled a breakout session on Tuesday morning. Because one issue raised was the availability of OpenType MATH fonts on operating systems, I believe it’s worth giving an update on the latest status…

  • 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.
