  • Creating HTML content with a fixed aspect ratio without the padding trick

    It seems to be a common problem, you want to display some content on the web with a certain aspect ratio but you don't know the size you will be displaying at. How do you do this? CSS doesn't really have the tools to do the job well currently (there are proposals). In my case I want to display a video and associated controls as large as possible inside a space that I don't know the size of. The size of the video also varies depending on the one being displayed.

  • William Lachance: Using BigQuery JavaScript UDFs to analyze Firefox telemetry for fun & profit

    For the last year, we've been gradually migrating our backend Telemetry systems from AWS to GCP. I've been helping out here and there with this effort, most recently porting a job we used to detect slow tab spinners in Firefox nightly, which produced a small dataset that feeds a small adhoc dashboard which Mike Conley maintains. This was a relatively small task as things go, but it highlighted some features and improvements which I think might be broadly interesting, so I decided to write up a small blog post about it.

    Essentially all this dashboard tells you is what percentage of the Firefox nightly population saw a tab spinner over the past 6 months. And of those that did see a tab spinner, what was the severity? Essentially we're just trying to make sure that there are no major regressions of user experience (and also that efforts to improve things bore fruit):

  • 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.
