  • 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):

Cheat sheet for Linux users and permissions

The Linux operating system is a true multi-user OS, meaning it assumes that there's data on every computer that should be protected, whether in the interest of privacy, security, or system integrity. Linux uses file ownership and permissions to manage file and folder access. For administrators who deal with different user environments all day, this system is easy to understand, calculate, and control. Read more

LAS 2019: A GNOME + KDE conference

Thanks to the sponsorship of GNOME, I was able to attend the Linux App Summit 2019 held in Barcelona. This conference was hosted by two free desktop communities such as GNOME and KDE. Usually the technologies used to create applications are GTK and QT, and the objective of this conference was to present ongoing application projects that run in many Linux platforms and beyond on both, desktops and on mobiles. The ecosystem involved, the commercial part and the U project manager perspective were also presented in three core days. I had the chance to hear some talks as pictured: Adrien Plazas, Jordan and Tobias, Florian are pictured in the first place. The keynote was in charge of Mirko Boehm with the title “The Economics of FOSS”, Valentin and Adam Jones from Freedesktop SDK and Nick Richards where he pointed out the “write” strategy. You might see more details on Twitter. [...] It was lovely to see again several-years GNOME’s members as Florian, who is always supporting my ideas for the GNOME games [...] Thanks again GNOME, I will finish my reconstruction image GTK code I started in this event to make it also in parallel using HPC machines in the near future.
