about:Mozilla's blockers and needinfos

On this rainy october day (well, at least it rains where I’m writing this) of the great year 2020, let’s take another few minutes to reflect on some great practices that we have at Mozilla and that would deserve to take over the world. Today, let’s talk about what you can do when your work is blocked.

about:Mozilla's #introduction channel - and how it could work for your project

Let’s continue this series on some of the great practices that we have at Mozilla and that your project may wish to adopt, too. This time, let’s talk about Mozilla’s #introduction chatroom.

Switching to Gitalk

Until now, this blog has been using Disqus as a comment mechanism. While it is very useful, I’m trying to switch to a less invasive (and I believe more privacy-safe): gitalk. I’ve left Disqus on in the pages on which users had already left comments. For other pages, Disqus is now deactivated.

about:Mozilla's Mentored Bugs - and how it could work for your project

2020 is a crappy year for pretty much everyone. As you may have seen, this includes organizations such as Mozilla. So I figured it was the best time to actually talk about good stuff! This entry should be the first of a series of short articles dedicated to some great practices we have at Mozilla and that I think many open-source projects could adopt. At its core, Mozilla is a community of open-source enthusiasts. When you’re new to an open-source community and you wish to start contributing somewhere, finding an entry point is often difficult. This is where Mentored Bugs come in.

Why Did Mozilla Remove XUL Add-ons?

TL;DR: Firefox used to have a great extension mechanism based on the XUL and XPCOM. This mechanism served us well for a long time. However, it came at an ever-growing cost in terms of maintenance for both Firefox developers and add-on developers. On one side, this growing cost progressively killed any effort to make Firefox secure, fast or to try new things. On the other side, this growing cost progressively killed the community of add-on developers. Eventually, after spending years trying to protect this old add-on mechanism, Mozilla made the hard choice of removing this extension mechanism and replacing this with the less powerful but much more maintainable WebExtensions API. Thanks to this choice, Firefox developers can once again make the necessary changes to improve security, stability or speed. During the past few days, I’ve been chatting with Firefox users, trying to separate fact from rumor regarding the consequences of the August 2020 Mozilla layoffs. One of the topics that came back a few times was the removal of XUL-based add-ons during the move to Firefox Quantum. I was very surprised to see that, years after it happened, some community members still felt hurt by this choice. And then, as someone pointed out on reddit, I realized that we still haven’t taken the time to explain in-depth why we had no choice but to remove XUL-based add-ons. So, if you’re ready for a dive into some of the internals of add-ons and Gecko, I’d like to take this opportunity to try and give you a bit more detail.

Possibly one step towards named arguments in Rust

A number of programming languages offer a feature called “Named Arguments” or “Labeled Arguments”, which makes some function calls much more readable and safer. Let’s see how hard it would be to add these in Rust.

Units of Measure in Rust with Refinement Types

Years ago, Andrew Kennedy published a foundational paper about a type checker for units of measure, and later implemented it for F#. To this day, F# is the only mainstream programming language which provides first class support to make sure that you will not accidentally confuse meters and feet, euros and dollars, but that you can still convert between watts·hours and joules. I decided to see whether this could be implemented in and for Rust. The answer is not only yes, but it was fun :)

Layoff survival guide

If you’re reading these lines, you may have recently been laid off from your job. Or maybe, depending on your country and its laws, you’re waiting to know if you’re being laid off. Well, I’ve been there and I’ve survived it, so, based on my experience, here are a few suggestions:

The BinAST diaries - Compression, part 1

If you have been following the work on the JavaScript Binary AST, you probably realized that we haven’t been communicating much recently. Sorry about that, we’ve been busy iterating on it! In this blog entry, I’d like to talk to you about our current main focus: file compression.

New blog: Space·Time Will Tell

New blog: Space·Time Will Tell

I have decided to keep this blog for professional use and move everything related to storytelling, role-playing games or improv acting to a new location. Without further ado, let me introduce Space·Time Will Tell! At the menu: a comic book tutorial for Fate RPG! using Tarot-like cards for storytelling! several elevator pitches for stories I haven’t had the time to write! the Space·Time Deck! the Ronin Time Bureaucrats! adventure and excitement!
