Hey folks! We have recently had a wonderful new release of #py5, read about the new 3D trimesh integration feature and the matplotlib TextPath integration.
That release was quickly followed by a release to fix some small issues that surfaced this last week. Please check out py5 0.10.9a1 and join us at https://github.com/py5coding/py5generator/discussions to share your experiences!

@movq@www.uninformativ.de From 2:50 PM to 3:23 PM AEST (+10 UTC) there was an outage. Everything went “up” on Down Detector, my EU region went offline, numerous sites were unavailable, and so on. Basically everything to/from the EU appeared to basically go kaput.

If your very popular project with lots of stars on GitHub is over 10 years old, and you’re still at a pre-1.0 version because you’re using SemVer and a 1.0 would mean making some kind of commitment and that’s somehow not desirable for you, then I think you’re doing something wrong. 🤔

#Processing & #py5 tip:
Remember the shapes you put on draw() will be redrawn over and over, and if they don’t move (leaving a trail) you might want to either clean each frame with background(...), or stop the draw loop (noLoop() in Processing or no_loop() in py5), otherwise you kill the anti-aliasing of the lines :D

”`python
import py5

def setup():

py5.size(200, 200)
py5.stroke_weight(2)
# a line that will drawn once only
py5.line(10, 10, 190, 90)

def draw():

# you could clean the frame here with background(200)

↳ In-reply-to » I finished all 12 days of Advent of Code 2025! #AdventOfCode https://adventofcode.com — did it in my own language, mu (Go/Python-ish, dynamic, int/bool/string, no floats/bitwise). Found a VM bug, fixed it, and the self-hosted mu compiler/VM (written in mu, host in Go) carried me through. 🥳

Alright, Advent of Code is over:

https://www.uninformativ.de/blog/postings/2025-12-12/0/POSTING-en.html

It’s been quite the time sink, especially with the DOS games on top, but it was fun. 🥳

In case you’re wondering: All puzzles (except for part 2 of day 10) were doable in Python 1 on SuSE Linux 6.4 and ran in a finite time on the Pentium 133. Puzzle 10/2 might have been doable as well if I had better education. 🤣

Thinking about doing Advent of Code in my own tiny language mu this year.

mu is:

  • Dynamically typed
  • Lexically scoped with closures
  • Has a Go-like curly-brace syntax
  • Built around lists, maps, and first-class functions

Key syntax:

  • Functions use fn and braces:
fn add(a, b) {
    return a + b
}
  • Variables use := for declaration and = for assignment:
x := 10
x = x + 1
  • Control flow includes if / else and while:
if x > 5 {
    println("big")
} else {
    println("small")
}

while x < 10 {
    x = x + 1
}
  • Lists and maps:
nums := [1, 2, 3]
nums[1] = 42

ages := {"alice": 30, "bob": 25}
ages["bob"] = ages["bob"] + 1

Supported types:

  • int
  • bool
  • string
  • list
  • map
  • fn
  • nil

mu feels like a tiny little Go-ish, Python-ish language — curious to see how far I can get with it for Advent of Code this year. 🎄

I just noticed this pattern:

Let me add some spaces to make it more clear:

    uninformativ.de 201.218.xxx.xxx - - [22/Nov/2025:06:53:27 +0100] "GET                       /projects/lariza/multipass/xiate/padme/gophcatch HTTP/1.1" 301 0 "" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36"

Some IP (from Brazil) requests some (non-existing, completely broken) URL from my webserver. But they use the hostname uninformativ.de, so they get redirected to www.uninformativ.de.

In the next step, just a second later, some other IP (from Nepal) issues an HTTP proxy request for the same URL.

Clearly, someone has no idea how HTTP redirects work. And clearly, they’re running their broken code on some kind of botnet all over the world.

My goodness, a new level of stupidity.

The bots are now doing things like this:

GET http://uninformativ.de/projects/lariza/feednotify/datenstrahler/slinp/countty HTTP/1.1
  1. That URL does not exist.
  2. By including http://uninformativ.de in that request, this instructs the webserver to do an HTTP proxy request. Of course, this isn’t allowed on my webserver (and shouldn’t by allowed on any normal webserver), resulting in HTTP 400. And even if it were, the target would be the exact same server, making a proxy request unnecessary.

And of course, it’s not just 50 hits like this or 100 or 1’000 or 10’000. No, it’s over 150’000 in the last 2 days. All from vastly different IP ranges of different cloud hosters.

This almost looks like a DDoS attack, but it’s just completely stupid. This feels more like some idiot vibe coded a crawler.

We had some gray soup with the occasional fine rain with strong wind gusts. Despite the bad forecast we took the train to Geislingen/Steige and strolled up to the Helfenstein castle ruin. All the colorful leaves were so beautiful, it didn’t matter that the sun was behind thick layers of clouds.

We then continued to the Ödenturm (lit. boring tower). By then the wind had picked up by quite a bit, just as the weatherman predicted. We were very positively surprised that the Swabian Jura Association had opened up the tower. Between May and October, the tower is typically only manned on Sundays and holidays between 10 and 17 o’clock. But yesterday was Saturday and no holiday. The lovely lady up there told us that they’re currently experimenting with opening up on Saturday, too, because there are some highly motivated members responsible for the tower.

We were the very first visitors on that day. Last Sunday, when the weather lived up to the weekday’s name, they counted 128 people up in the tower. Very impressive.

The wind gusts were howling around the tower. Luckily, there are glass windows. So, it was quite pleasant up in the tower room. Chatting with the tower guard for a while, we got even luckier: the sun came out! That was really awesome. The photos don’t do justice. As always, it looked way more stunning in person.

Thanks to all the volunteers who make it possible to enjoy the view from the thirty odd meters up there. That certainly made our day!

After signing the guestbook we climbed down the staircase and returned to the station and headed back. The train even arrived on time. What a great little trip!
