I think the protestors in Portland are doing really important work. If Portland was really burning down, why would there be a dude in a chicken suit yelling at ICE. It gives the world visual evidence that the president is lying.

I liked this graphic, neat to see how common letters got extra space.

Just in case you were wondering why capital letters are also called "UPPERcase" :)

"Today, I have only one dream: that our children live in the best possible world. Between the global rise of fascism and climate warming, this dream faces many challenges. But we can fight for it. For this, as always, we need to gather people and unite around the right causes." 👏

Love this call to action:

- So send the tweet.
- Use the disfavored word.
- Donate to an embattled non-profit.
- Subscribe to your local paper.
- Read a banned book.
- Show empathy for your fellow human beings.
- Throw the (metaphorical) tomatoes.

I had my first run-in with Trump 2.0 complicity days after the 2024 election.

Since then we've seen more examples from media, universities, law firms & many others.

Does what the little guys do matter? Yes, more than ever.

Dr. Jane Goodall filmed an interview with Netflix in March 2025 that she understood would only be released after her death.

Does the news reflect what we die from?
The image presents a comparison of the leading causes of death in the United States for 2023 and the media coverage these causes receive from three news outlets: The New York Times, The Washington Post, and Fox News. 

In the footer, it notes the data sources, indicating that the information is based on media mentions from Media Cloud (2025) and death data from the US CDC (2025) and the Global Terrorism Index, with a clarification that values are normalized to sum to 100%.

Doesn't hurt to be a little extra careful on Halloween. 🎃😱

Race is an interesting example, I am drawn to the resume studies where names are manipulated. They're not perfect but it seems like a clean way to get evidence of racism.

I moved over from hover+netlify and I've been very happy. But, I do anticipate it will get more expensive at some point based on the company's financials.

I really like Cloudflare, but I worry about when they shift from revenue growth to profit maximization. Enshittification imminent?
Cloudflare's net income has been negative over the past five years, while revenue is steadily increasing (Google finance graph).

Agree, but I think on both of those it took a lot of work to convince people of those causal effects (it's hard to build trust when there's no exogenous variation).
andrewmarder.net
Another way to phrase my question:

What do you think of the statement "no causation without manipulation"?
andrewmarder.net
I think of it as an opinion question. How much do you trust casual parameter estimates when there is no source of exogenous variation?
andrewmarder.net
One cannot identify a casual parameter without a source of exogenous variation, agree or disagree?

I've enjoyed switching over to Cloudflare Pages. One gotcha there is they have a 25 MB filesize limit.
