Oh dear, I'm still working on erosion. For quick experimentation, I've even broken out #Python, #Jupyter, #numpy and #matplotlib.
Here's a neat picture showing that something is working a little bit, although I think usually rivers are lower than the surrounding terrain, not higher.
Where will this end?
Tired of silent #NumPy errors? Christopher Ariza reveals how to fully annotate your np.ndarray with shape & dtype hints. Enable static analysis with MyPy and runtime validation with StaticFrame's CallGuard. Write more robust Python code. Read the full article to learn more.

DumPy: NumPy except it's OK if you're dum
Interesting. A good part of teaching/learning #numpy is being aware of the many syntax/shape gotchas. This looks like it can get rid of it. 
Cobbled together an #ExoLabs cluster to fuck around with #devstral a bit, since it's kinda too big for my M3 Max daily driver. While in the process of bringing up nodes the model hit a bug in the #MLX #Python module that deals with inference model sharding related to passing around MLX vs Numpy data structures.
For shits and giggles and also not being a top-tier #Numpy data structure debugging guy I asked Devstral to look at the bug and figure out a fix. After one wrong turn it came up with a fix which I applied to the other nodes and now it's happily sharding the bigger Devstral models. Not sure about vibe coding as a social contagion but from a “How close are we to #Skynet”-perspective I think we're cooked, chat.
Anyway enjoy your Memorial Day weekend

For #PyQGIS raster masters:
use QgsRasterLayer.as_numpy() to get your raster layer as numpy array.
This was silently added in QGIS v3.40,
thus no one seems to know!

Hydra-jupyter package updated 
https://github.com/lauraporta/hydra-jupyter
The readme should be sufficient for now to get started.
There is an HydraSession class now that handles well two and three dimensional numpy arrays!
Also I added an iPython magic function with which I can write directly hydra code!
Now I have to think which #numpy arrays will be cool to send.

Oh look, a rainbow! Exploring the Visible Spectrum with Python Part 1
In this article I write Python code to calculate the frequencies, wavelengths, energies and RGB values of light across the visible spectrum. (Next week in Part 2 I plot the data using Matplotlib.)

How funny... a tutorial site (geeksforgeeks) presenting an example for numpy.vectorize() WITHOUT EVEN INCLUDING THE CALL IN ITS CODE... no human writer would have made this error.
I don't understand the interpolation step of #perlin #noise generation.
I have gradient vectors at the grid points. I have points inside each grid square.
If I call the gradient vectors unit vectors, then the dot product of a gradient vector with a point-position vector is already scaled by distance. It will also be scaled by distance from the other corners.
Is that not already interpolated?

II've heard of Perlin #noise before but never dug into it.
Yesterday I wanted it for a project and found some #python code for it (#numpy apparently doesn't supply Perlin natively...?)
The code works, but it isn't at all clear what the arguments mean or how I'd use it for the project I want.
So *obviously* now I am making my own that makes more sense to me. And also supports multiple octaves.
I mean...it's a day off. What else am I going to do?
