"The complex web of human interactions that thrived on the internet’s initial technological diversity is now corralled into globe-spanning data-extraction engines making huge fortunes for a tiny few."
What if we refused to accept ‘Internet ecosystem’ as just another BS marketing term?

And instead treated the internet as what it is; a deeply damaged and suffering monoculture that needs radical care.

And what if we rewilded the absolute fuck out of it?!

The internet has become an extractive and fragile monoculture. But we can revitalize it using lessons learned by ecologists.

How Men and Women Spend Their Days
Women and men tend to spend their days differently in the United States. Varying responsibilities and priorities will do that.

Social scientists often talk abt the contact hypothesis theory for which interpersonal interaction under certain circumstances can significantly improve intergroup relations. We don‘t know if public transit systematically creates these circumstances, but we do know that cars systematically do *not*.
i think if you ride public transit enough you learn that most weird behavior is not dangerous, and conversely i think driving a car teaches you that everyone is trying to kill you at all times

A very nice rundown of what private data sources can and cannot tell you about the state of the economy right now.
Thanks to the shutdown, we didn't get the first estimate of Q3 GDP today. And private-sector data offer no good substitute for official GDP.

The shutdown offers lots of lessons about what private sector data can and can't do.

The government shutdown provides an unexpected test case for an increasingly urgent question: What would happen if official economic statistics became less useful, whether through declining resources,...

I’m seeing some misinformation about pseudo-random number generator best practices going around the internets. Let’s talk about why the pseudo-random number generator seed you use shouldn’t actually have any impact on your results and, consequently, you can choose whatever seed you damn well please.

We need to have a conversation about random seeds. Don't use 42.

If your random seed is 42 I will come to your office and set your computer on fire🔥
Figuratively. More likely you'll get a stern talking to.

I really appreciate this design principle from @obsidian.md:

"Obsidian uses open file formats, so you're never locked in. You own your data for the long term."

I'm trying the same approach with my photos, moving from Google Photos to digiKam.

Inspired by W. E. B. Du Bois’s “data portraits” about the state of daily life for Black people after Emancipation, a show at Print Center New York wants to do more than convince. It means to complicate our reading of data.

As a historian, I can certify that we are in the bad times. But bad times eventually end.
In the meantime:
• Figure out a small way to help someone
• Figure out a small way to fight back
• Figure out a small place to find joy
• Figure out a small way to grow and thrive

And do it often.
