[Advent of Code 2025 Day 4 code uiua]
And, thanks to #uiua 's built in gif support, it just needed a small edit to keep the history of the grid and a &fwa "out.gif" gif 24 to output this animation of the sequence of barrels being removed:
[AoC 2025 Day 1 in Uiua]
I've completed "Secret Entrance" - Day 1 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/1
Doing this in #uiua and I'm rusty so this is probably inefficient for pt2 but I wanted to chunk it into logical pieces. Listing is the parser and took me […]
Doesn’t uiua #uiua just replace local variables with planets or, for macros, placeholders? I love the language’s radically functional vibe, but still, something just seems either unnecessary or insincere here

So this is my part one solution to AoC 2024 Day 2, written in Uiua. The whole thing is 18 characters long:

Having a blast learning about array languages. Shoutout to @kaikalii.bsky.social for creating one that’s this approachable and intuitive!

And yet the underlying implementation is almost a one-to-one match with the physical memory where the data is actually stored. Am I freaking out for no reason or am I right in thinking there’s something really inportant going on here?

A simple digit-rotation formula using modulo, explored across Julia, R, APL, and Uiua. Great for comparing basic operations across languages. jcarroll.com.au/2025/05/03/r...

made that kaprekar's routine thing in #uiua (i really hope thats an actual hashtag)

Yow. I got to the bottom of the first major tutorial page with exercises on #Uiua and was really shocked at how my mind just broke on point-free tacit syntax.
That was cool.
**Output Comments** A comment that starts with additional `#` is an _output comment_. The formatter replaces the text of an output comment with as many values from the stack as there are extra `#`'s. Click Run to try it out! 1 2 3 #### 3 #### 2 #### 1 + ### 3 ### 3 + ## 6 ------ 6
#Uiua "output comments" strike me as an interesting way to inspect the stack while you're debugging formulae.
I wrote up my experience of using #uiua for 2024's #AdventOfCode. Many languages could learn a lesson or two from the frankly beautiful developer experience of Uiua's web repl.

I support full regex too of course, but the ability to just 'match' bits of a string directly into variables is waaaaay to convenient to leave out; I find it's what I want in most cases, but without the ceremony of unpacking matches/groups from a regex.
Props to #uiua for the idea there.
Essai de fusion de deux tableaux triés avec #Uiua sans utiliser ⍆ (sort).
Une fois fait, cette impression que c'était faisable en cinq/six symboles ne me quitte pas, à tel point que mon code serait risible. Je me demande si chaque code en #Uiua ne me donnera pas cette désagréable sensation. 🤔
Day 25 of #AdventOfCode using #uiua

Friends, we've reached the end of the line.
I'll do a write-up in the new year of my experiences, but in the meantime here's a cute little one liner for day 25.

This is possibly some of my favourite uiua I've ever written - it makes part 1 a one-liner!
Part 2 I just did by hand because it was so easy to do it that way (iykyk)

Day 2 of #AdventOfCode using #uiua
This would have been significantly simpler if every report had the same number of levels, and I brute-forced part 2 without much thought.
Answer in replies, full code and tests on GitHub.
the first part of day one of #AdventOfCode can be solved in #Uiua using a few well-placed flips. the actual challenge (for me at least) might turn out to be reading the actual file.
It’s been a long day. I forgot I did the #AdventOfCode puzzle this morning until just now.
This year I’m (a) resolving take it slowly because December is already busy enough (b) trying to learn #uiua (c) attempting to leave myself plenty of useful notes.
In spirit of (a) I only did the first […]
