Did you know that ISO 8601 is a very large standard that describes more than a single date and time format?

It describes periods, repetitions, many different syntax of describing years, week-of-year, day-of-year, seasons, quarters, semesters, trimesters.

It's mostly unknown because the standards are paywalled: you can't just read ISO 8601 without paying ISO money.

Most of the time, when people refer to ISO 8601, they mean the subset that is described in RFC 3339.

When an eel has a maw
with a pharyngeal jaw,
that’s a moray.

When the jaws open wide
and there’s more jaws inside,
that’s a moray.

When it skulks in a reef
and has two sets of teeth,
that’s a moray.

When an eel bites your thigh
and you bleed out and die
that’s a moray.

We have a new back porch friend! She's wary but doesn't seem to mind me sitting out here watching her build her miniscule nest. :moomin_sparkles:

We've had a few quite warm days, but the nights were below zero. Found some some frozen birch sap. Sweet.

@cbdawson XKCD helped me to understand the world. I wish there were such resources in my childhood.

In Germany, teaching the Holocaust is mandatory.

It includes visits to concentration camp, museums, etc. They don't shy away from their own ugly history. Yet the kids aren't damaged; they're strengthened, matured, humbled. The U.S. needs to do same with slavery.

Not that complicated.

@robpumphrey Yes, it looks like Sarcoscypha coccinea. Are you in the northern hemisphere? :)
