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. en.wikipedia.org/wiki/Symmetri

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 kind of like Mastodon's multicolumn "advanced web interface", except that the columns are fixed-width and far too narrow.

Apparently the way people mess with this if they want to is to adopt a user stylesheet, but this is probably too much to ask of most users (the world intended by CSS's designers in which user stylesheets are universal, sites are all designed to work well with them, and there are popular tools to manipulate them never really came).

I started a repository of little experiments.

github.com/mjambon/dev-random/

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 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.

I'm translating an figure for a article. I have an alignment problem due to the 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 .

This is the file's page: commons.wikimedia.org/wiki/Fil
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?

It took me this long to realize that while posts with are usually worse than those without, the ones containing hashtags I care about make a really good feed.

Twitter is 56.4 % men and 43.6 % women. For comparison, my latest gendered followers are 36 males (73 %) and 13 females. Over the same period, my followees are 45 males (79 %), 12 females. I would have guessed 80/20.

I confirm that I like the rules of this Mastodon server, qoto.org. I find it deplorable that some servers block it because it doesn't block other servers. Please let me know if there's more to it.

Why is it a "restriction site" and not "cleave-land"? 🧐

Christmas lichen (Cryptothecia rubrocincta) from Myakka River State Park, Florida. Apparently they don't produce apothecia (fruiting bodies with spores) like most lichens. Reproduction is instead via isidia, surface outgrowths that contain the partnering fungal hyphae and algae. #lichen #lichens #fungus #fungi #nature #biology #Christmas

High temperatures in Iowa today are lower than those on Mars.

Despite that, with the right technology, I do believe we can make Iowa habitable for humans.
