I’d like to nominate Dart (Pascals Triangle specifically), but the lack of a working test runner is probably too much of an impediment for students.
It looks like Vim script and Emacs Lisp are no longer featured languages in the latest iteration of the schedule. That’s unfortunate.
Since Red is a DSL for creating GUI apps, it seems fitting that it would be featured during one of the Apps weeks. Maybe switch it with CoffeeScript on Pascal’s Triangle?
“Two Bucket” can be solved in a clever way, by solving a Diophantine equation . As far as I know the only language that has a dedicated function for the “extended Euclidean algorithm” built into the standard library is Julia (gcdx). If we get this exercise translated to Julia before October that would be a nice thing to show.
(edit: other languages have related functions, but of all the programming languages I checked Julia was the only one with a dedicated function that calculates Bézout’s coefficients directly. Thanks, @dreig)
A bunch of languages seem to have modular inverse in their standard lib: RosettaCode-Modular-Inverse
Among them Python, Go, Java/Kotlin and Racket (though math-lib is currently missing on exercism).
Yeah, we were using the full Racket distribution for the test runner until around July of last year. Using the minimal Racket distribution reduced the test runner image size by about 80% to 60 MB since we’re not pulling in DrRacket and Scribble dependencies. Adding math-lib by itself to the minimal distribution pulls in most of those dependencies. At that point, we might as well go back to the full Racket distribution, but we’re trying to keep test runner image sizes at reasonable sizes across the board.
I should put a note in the track-specific documentation about this situation since the docs defer to the official Racket installation docs which prefer the full distribution. However, I haven’t heard yet of any other students having issues submitting code that only passes locally.
I have a suggestion to make the dart test runner faster, but I don’t know if it is feasible:
The reasoning behind this would be that we don’t want student to have to write their code in a specific editor.

I spent some time updating the list yesterday: 48in24 exercises - Google Sheets Let me know if you feel anything is wrong or could be improved.
Here are some of the constraints I imposed on myself:
- Select exercises which difficulty is such that many students will be able to solve it. For example,
alphameticsandpovare quite difficult and might be too hard for a lot of people to solve. - Select one featured track from the corresponding 12in23’s month. So for the exercises in February, one of the featured tracks is taken from the Functional February tracks.
- Feature tracks that allow the exercise to be solved in interesting ways.
- Feature tracks that allow for different approaches (e.g. one imperative, one object-oriented and one functional language).
- Feature as many tracks as possible.
- Minimize the number of exercises needed to be implemented (the current selection only requires three exercises to be implemented).
- Attempt to spread out the tracks as much as possible (so no two consecutive weeks featuring the same track).
- Don’t feature tracks that are editor/platform specific or hard to work with. This includes Delphi (Windows-only), Objective-C (mostly mac-specific), PL/SQL (hard to get setup locally), Vimscript (requires Vim-compatible IDE) and Emacs Lisp (requires Emacs).
There is an open PR to add this grid: Add page for 48in24 implementation status by ErikSchierboom · Pull Request #6712 · exercism/website · GitHub
Yeah - we’re not going to feature any tracks that don’t have a working test runner. That said, Pascal’s Triangle is late in the year, so there’s time if anyone can work out how to speed up the test runner!
It would be interesting to solve a problem in Zig and C or C++ and Rust in the same week.
It would, but that is what 12in23 is for. For 48in24 we try to feature tracks that allow for a variety of approaches.

Can I be added to the Dart team please. I have some PRs and I can’t add reviewers.

You’ve been added to the Dart team.
Can I be added as a Red maintainer? 
Are the languages arranged in recommended order of completion from left to right?
No. All three languages are chosen to be different each month and challenge in different ways. Thanks for asking
Would it be possible to swap one of the Perl exercises for Raku to get phone-number?
Its a good one for highlighting Raku’s grammar system in my opinion: m-dango's solution for Phone Number in Raku on Exercism
Edit: Perhaps with secret-handshake? m-dango's solution for Secret Handshake in Perl on Exercism
