Wasting by SiegeLord Land on disease-wracked planets to deliver supplies, and help develop a cure!

TINS 2026 is coming in May: tins.amarillion.org

Most jams just have a theme, but TINS gives you 5 rules! Restriction breeds creativity. Here's my 2024 entry: siegelord.itch.io/wasting Deliver supplies in space! The rules were: Trains, Art Nouveau, Customization, Quadratic Formula

I invite you all to my 72h Game Jam!

Thanks for sharing, I'll see if I can learn new tricks.

In the mean time I'm optimizing and cleaning my own solver and it's getting to a decent state.

amarillion.github.io/genuary26/da...

On my laptop, I can check ~5M permutations per second for the WASM version, and ~20M/s with native C++.

Yes, this video was my inspiration.

Matt Parker mentions that they found all 1.7M+ solutions, but I couldn't find more information.

I think it's by @mscroggs.co.uk - Matthew, are the sources for your partridge problem solver public somewhere?

Rest assured, it does fit in the end 😀 Just watch the animation play out.

I wrote a solver to generate all possible solutions.

But it's so slow, I thought I better start the animation from a near-solution.

#Genuary #Genuary2026 #Genuary14

Prompt: Everything fits perfectly!

Fit 9 squares of 9, 8 squares of 8, etc., inside a square of 45. A.k.a. the "partridge problem" (think of the Xmas carol).

See the animation at amarillion.github.io/genuary26/

Here using both the ZX Spectrum palette and resolution.

Revisiting another classic. Drawing Bresenham lines in XOR mode, creating this pretty Moiré pattern.

On #zxspectrum, XOR mode was an optimization, but with current tech, it's a performance hit as it requires reading bitmap memory, a big no-no.

#Genuary2026 #Genuary #Genuary3 "Fibonacci forever" - I went for a classic visualization of the golden spiral. Matching Fibonacci rectangles with a logarithmic spiral is actually rather finicky.

To be honest, it's only showing one principle here: squash & stretch.

Starting off #genuary with a very simple animation. Genuary is one creative coding prompt per day, let's see how many I can get done in a month!

It might be different for you because you're catering to a specific niche...

But IMHO bsky and twitter are a very poor way to reach actual gamers.

Smart phones are like little babies, constantly whining for attention with the permission checks, the accounts and the pin codes, the migration wizards, the id scanning, the terms of service, the cookies, the feedback requests, the pop-up ads, the feature tours, the notifications... 😫

soft locked TOS screen

Icing on the cake from @fairphone.bsky.social:

Our brand-new $$$ FP6 was soft locked on the TOS approval screen. Checkbox and Next button overlapping so no way to click either.

I got through this by decreasing text size in the accessibility menu.

Without help, my mom would have had to return it.

I had to go through this for half a dozen apps on two separate phones. Draining, exhausting, and impossible to figure out for non-tech people.

As far as I'm concerned, Google, Android, Chrome, ING, DIGID, SIgnal, Samsung and Fairphone all share equal blame in this UX disaster.

4/n

This is then followed by each app eagerly offering to show you around to discover all the new features. Yay!

3/n

Even with the migration wizard, for each app you need to:
* Remember your username & password
* scan passport or ID (in case of banking & digid)
* approve TOS and/or accept cookies
* Set up a new pincode
* Click away ads
* Set permissions for location, notifications, file system, etc.

2/n

How horrible is the user experience of setting up a new smart phone 🤮.

Today I did tech support for my elderly parents who both bought a new smart phone - they were still on Android 9 and essential apps (banking) stopped working, so they needed a new phone.

Here follows a rant 1/n

POV: you're a non-native developer in the Netherlands and you have to pronounce the word Buienradar 100x during your talk 😄 (No shade, it's a great talk by Neel Bhatt) #jfall

Of course that station has changed completely. Back then it looked more like a dirt starter base.

Me in front of a train station

This takes me back... I'm here to speak at #jfall. But Wageningen is also my alma mater you know...

And this Thursday you can find me at #JFall.

I'll be speaking on two topics, no less, and both of them are about #gamification. i18n-puzzles AND the micro frontend game.

Last week, me on stage speaking about #i18n-puzzles. Thanks for having me @tweakers.net developer summit!

Het Duitse equivalent van steenkolenduits

It occurred to me that the examples you give are perfect for the backend-for-frontend pattern, as it's now much easier in Java to combine, bundle, or transform requests to a backend.

There was some discussion on avoiding UTC for *future* timestamps. I'm still looking for good examples (involving instants in time) where UTC doesn't fit. Do you know any?

Yes riding the escalator up while this view unveils, is how Antwerp says "welcome".
