  • Community Management Update

    I have a couple announcements for today. I’d like you all to welcome our two new community managers.

    First off Kiki has officially joined the SUMO team as a community manager. Kiki has been filling in with Konstantina and Ruben on our social support activities. We had an opportunity to bring her onto the SUMO team full time starting last week. She will be transitioning out of her responsibilities at the Community Development Team and will be continuing her work on the social program as well as managing SUMO days going forward.

    In addition, we have hired a new SUMO community manager to join the team. Please welcome Giulia Guizzardi to the SUMO team.

  • Mike Hoye: Ten More Simple Rules

    The Public Library of Science‘s Ten Simple Rules series can be fun reading; they’re introductory papers intended to provide novices or non-domain-experts with a set of quick, evidence-based guidelines for dealing with common problems in and around various fields, and it’s become a pretty popular, accessible format as far as scientific publication goes.

  • Henrik Skupin: Example in how to investigate CPU spikes in Firefox

    So a couple of months ago when I was looking for some new interesting and challenging sport events, which I could participate in to reach my own limits, I was made aware of the Mega Hike event. It sounded like fun and it was also good to see that one particular event is annually organized in my own city since 2018. As such I accepted it together with a friend, and we had an amazing day. But hey… that’s not what I actually want to talk about in this post!

    The thing I was actually more interested in while reading content on this web site, was the high CPU load of Firefox while the page was open in my browser. Once the tab got closed the CPU load dropped back to normal numbers, and went up again once I reopened the tab. Given that I haven’t had that much time to further investigate this behavior, I simply logged bug 1530071 to make people aware of the problem. Sadly the bug got lost in my incoming queue of daily bug mail, and I missed to respond, which itself lead in no further progress been made.

    Yesterday I stumbled over the website again, and by any change have been made aware of the problem again. Nothing seemed to have been changed, and Firefox Nightly (70.0a1) was still using around 70% of CPU even with the tab’s content not visible; means moved to a background tab. Given that this is a serious performance and power related issue I thought that investigation might be pretty helpful for developers.

    In the following sections I want to lay out the steps I did to nail down this problem.

  • My StarCon 2019 Talk: Collecting Data Responsibly and at Scale

    Back in January I was privileged to speak at StarCon 2019 at the University of Waterloo about responsible data collection. It was a bitterly-cold weekend with beautiful sun dogs ringing the morning sun. I spent it inside talking about good ways to collect data and how Mozilla serves as a concrete example. It’s 15 minutes short and aimed at a general audience. I hope you like it.

  • 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.
