New blog post: Deriving the Elm Architecture
https://purplekingdomgames.com/blog/2024/03/05/deriving-the-elm-architecture
I've been playing around with Scala Native 0.5.0-RC1 this weekend.
Originally I was hyped for the multithreading, but now I want that sweet compilation speed. Some of my projects are compiling in ~1/4 of a time on a full build.
This is going to make debugging performance issues so much better.
This was quite the Heisenbug: https://github.com/JD557/minart/pull/474
Some sound files were corrupted, but only when loaded from the Java resources on a specific application.
When I loaded them on unit tests or Scala CLI scripts they would work fine. Even something as simple as loading them from a file (instead of a Java resource) would work .
Turns out sometimes InputStream.read(bytes)
does not read all the bytes (duh, that's why it returns the number of bytes read) and I was not handling that... not sure how I didn't hit this earlier .

is a new functional abstraction, the "orderator", which is a generalization of streams.
Like a stream, it's lazy and chains of operations fuse nicely. Unlike a stream, it also supports skipping ahead using logarithmic search.
This abstraction ends up being sufficient to express a large variety of join algorithms (inner and outer joins, foreign key joins... ), set operations (union, intersection, subtraction), and more.
The most amazing part is that chains of these operations fuse together nicely, yielding performance similar to a hand-rolled monolithic loop, but with highly-readable and modular code.
The @unison library for this worked out great, especially that we get to mix this abstraction with other effects.
cc @mpilquist you might enjoy this!
Here we have the great @davesmith00000 on an interview about game development with Scala.js
A bit of a weird post, but I just got a package in the mail and wanted to give a shout out to DragonBox's customer support.
I messed up a pre-order there (pro-tip: if you are moving countries, don't pre-order stuff to the country you are moving away from ) so I really needed an emergency address change to a different country.
They were not only quick and helpful, but also super nice.
Also, it feels really good to talk straight to a human instead of going through layers of chat bots and FAQs.
10/10 experience.
Not sure if this is a thing on other ActivityPub frontends, but one feature that I really like here (and wish Twitter had something similar) is being able to see my actor inbox as a timeline.
It's pretty much posts from people I follow (including comments) plus comments to their posts. In essence, a timeline with just a bit of serendipity from people I don't know.
It feels like a nice middle point between "new posts of people I know" and "top posts from complete strangers".
Today marks my last day in Berlin.
It was a fun little adventure, but all things must come to an end eventually.
It's never easy to say goodbye, but I can say that I'm excited for what comes next.
Just did a bunch of releases:
- Minart 0.6.0-M2: https://github.com/JD557/minart/releases/tag/v0.6.0-M2
- Interim 0.1.6: https://github.com/JD557/interim/releases/tag/v0.1.6
- Späti 0.1.1: https://github.com/JD557/spaeti/releases/tag/v0.1.1
It runs! Scala Native on the Playdate! #playdatedev #playdate
TIL that you can use Scastie with Scala JS and, if one of the expressions returns an Element
, it is rendered on the worksheet:

I need to work on the Minart APIs to make this use case a bit more ergonomic, but this looks pretty cool for demos.
I've been seeing a lot of discussions in Portugal regarding https://expresso.pt/sociedade/2024-01-11-Exodo-tem-um-impacto-brutal-30-dos-jovens-nascidos-em-Portugal-vivem-fora-do-pais-6b42d39c (article in PT - 30% of Portuguese aged between 15 and 39 are emigrants)
I was a bit curious about this, but apparently the study was not yet released and the closest thing I could find was https://diasporafordevelopment.eu/interactive-map/, which I'm not sure how up to date it is and doesn't seem to provide any tables.
So I just scrapped the data and generated a markdown table, in case someone is curious about this kind of stuff: https://gist.github.com/JD557/22ee5494ce99af696e1fda5747eef18e
That gist also provides the raw JSON data that I used and a #Scala CLI script to generate a CSV, in case you want to do some further analysis.
Ultraviolet 0.2.0 released
Our #Scala 3 to GLSL transpiler lib is up to date with Scala.js and has received a few minor improvements.

Here's a new article on Free, in which I try to explain how it's merely the defunctionalisation of Monad in its most uncomfortable configuration: https://nrinaudo.github.io/articles/free_monad.html
Just came back to Portugal for the holidays.
It was kind of weird leaving the plane, seeing the blue sky and feeling the Sun's warmth.
The last weeks (maybe months?) in Berlin have been so gray that I kind of forgot how good this feels .
Added some fog, ceiling and sky to my raycaster tests, along with a larger map.
Being able to use Tiled as a map editor really helps for stuff like this.
Sorry for the bad video quality, I think the dark colors really mess up the compression.
Assets used (apart from the ones already mentioned in the previous post):
This year marks my 3rd winter in Berlin.
When I moved I thought the worst would be the cold weather, but that's actually pretty manageable. The small days are a pain, however (I had no idea about this "winter blues" thing).
It's kind of hard to explain, but I start to feel kind of tired and unmotivated when the days get shorter. I really need to leave the apartment a bit when there's still sun outside (even if the weather sucks).
It's also kind of bizarre how generalized this seems to be - You have a time of the year where people are gloomier than usual and just know that "it's normal, it's the winter".
FWIW, going to the office and to the gym has been helping quite a bit. If you are in a similar situation and have that option, I recommend trying it.
I do usually enjoy working from home, so this has the weird side effect that I actually go to the office more often in the winter when it's cold, raining and snowing than in the summer.
I've been trying to use this year's #adventofcode to learn Zig.
It has been an interesting experience so far. It's nice to work with a lower level language once in a while, and Zig does have some very exciting ideas, such as nice safety features along with it being very easy to ensure some properties about the memory allocations (e.g. no heap allocations).
However, I would lie if I said that I enjoyed the experience. I think the project has a bright future, but the ergonomics are lacking a bit, which is to be expected for a young and less mainstream language (namely regarding documentation, stdlib and compiler error messages).
Maybe some things are just not possible to do but, for example, using iterators in Zig really makes me miss Scala iterators. String parsing has also been a huge pain point.
It's not awful by any means, but personally I would be happy to see Scala Native competing with Zig in performance, so that I could use that instead (biased opinion, I know ).
The chat on the #advent-of-code channel on the Scala Discord has been lively and educational so far this year — hope to see you there. https://discord.com/invite/scala
