Candy cap #mushrooms in the neighborhood. The owner of the patch had no idea! They're very fragrant mushrooms once dried. Their smell is reminiscent of maple syrup. They go for about $1/g on eBay ($30/oz)!

[in response to a FB post about "inorganic" mushroom farming]
Note that in chemistry, and generally in science, "organic" is said of anything that contains carbon such as carbohydrates, proteins, DNA, psilocybin, and pretty much any large molecule involved with living organisms. "inorganic" is anything that doesn't contain carbon such as table salt, water, many rocks, and metals.
It is to be distinguished from the marketing term "organic" which means something like "I don't need no school to know what's good for me".

"vertex-transitive" is what I was looking for. Woohoo. https://en.wikipedia.org/wiki/Vertex-transitive_graph

If I understand what a graph automorphism is, what I want is a name for the graphs that satisfy:

For each vertex pair (u, v) there is an automorphism f such that f(u) = v.

A symmetric graph is not exactly that, and I'm a bit confused. https://en.wikipedia.org/wiki/Symmetric_graph

How do you call a graph where all the nodes are equivalent in the sense that each node sees the same graph structure from its own perspective? "isotropic", maybe?

Examples:
- a polygon
- an infinite grid
- a complete graph
- a toroidal grid
- n nodes 0 ... n-1 such that each node i is connected to nodes { (i+offs) mod n | offs in offsets }, given a list of offsets i.e. a subset of [1, n-1]

I started a #git repository of little experiments.

https://github.com/mjambon/dev-random/tree/main/001-max-reachability

The rules are:
- each experiment must take no more than a day, and ideally no more than 4 hours;
- there must be some text that explains the idea;
- there must be some #code that illustrates the idea.

I hope this will be fun and easily fit into my personal time. At a pace of 2 per month, that's 24 ideas with code per year, which would be pretty great. I could also get 5 of these done over a vacation week without ruining my family time.

There's something about bands named after one of their early songs. I can think of 4 such bands right now. Enjoy.

In chronological order:
- Indochine https://www.youtube.com/watch?v=QTJkVdXrr7A

Il y a un concert de Tiken Jah Fakoly sur Arte (90 min). C'est du bon #reggae, je recommande. https://www.arte.tv/fr/videos/107538-014-A/tiken-jah-fakoly/

I'm translating an #svg figure for a #Wikipedia article. I have an alignment problem due to the #font being not available everywhere. Is there a way to right-align text boxes independently of the actual font being used? I want them to remain editable as text. I'm using #inkscape.

This is the file's page: https://commons.wikimedia.org/wiki/File:HarmCausedByDrugsTable.svg#%7B%7Bint%3Afiledesc%7D%7D
In my browser (Chrome on Ubuntu), the text is misaligned (image 1). Image 2 is the screenshot of the relevant SVG code.

From what I can gather, text-anchor:end is indeed what we want to ensure right-alignment but it's not working. Any idea on how to make this work?
