Operator? Who… me?

When you go to a restaurant and eat a meal they’ve prepared, you’re a diner. But when you make a meal at home and eat it, although this accomplishes something similar, your role is very different. You aren’t a diner anymore; you’ve created and consumed the meal.

In software today, you’re either the developer or the user. The developer makes the software. It works one way, maybe with some settings to work a little bit differently. The user uses the software, conforming to its best practices and intended workflow.

Similar to the role shift when you cook a meal and eat it, there’s a role shift away from β€œuser” that happens when your OS is made of core primitives which you can modify and recompose. In this role, these β€œuser-developers” are operators of their machines, as they once were in the first few decades of computing. But you won’t be building your system all day; it will grow with you as you use it. In this handbook, you’ll learn how we’ve set it up to get you started. And when you decide something could be changed to support your best work, you will be able to make that change.

With your new system, you are now the operator.

I'm a fan of Alexander Obenauer's "operator".

Defuddle now has a website!

This means you can use Defuddle anywhere to get the main content of a page in Markdown format.

You can simply add "defuddle.md" before any URL, use it via curl, Skills, CLI, or add it to your app via NPM.

Maybe "rigorous fact checking" isn't quite right. More like "rigorous interrogation"

It won't be like this forever. But it won't change until we build something better to replace it.

Love what Hank is saying here about algorithmic social media. We are already living in a world where people trust AI output without rigorous fact checking. We have been for a while now.

Compiled with the hope that a record of the random things people do around here can save some duplication of effort except for fun.

Here is some little known data which may be of interest to computer hackers. The items and examples are so sketchy that to decipher them may require more sincerity and curiosity than a non-hacker can muster. Doubtless, little of this is new, but nowadays it's hard to tell. So we must be content to give you an insight, or save you some cycles, and to welcome further contributions of items, new or used.

How it works.

Generate or choose a random string. Prepend $.

Add it to your post.

Add the same tag to related posts.

Search the tag and every post carrying it appears regardless of when it was posted or who posted it. Each post remains autonomous on the timeline. No post is subordinate to another. Yet through shared tags, they form an organic network.

A thread is vertical. The Mezzanine is horizontal.

Posts move forward in time. Yet tags automatically create backward connections to earlier posts and open channels for future additions or third-party contributions. The motion is always forward, but the structure permeates past, present, and future. This is the model of temporal interpenetration.

Edmund McMillen Wants You to Ask the Uncomfortable Questions A frank conversation about Mewgenics, troubled childhoods, and anxious parenthood

Something I've been thinking about since this interview:

Yes, art is inherently political -- even if its creator doesn't like or claim or politics. But art is also autobiographical. And those autobiographical veins are worth mining.

This Is What It Looks Like When Nothing Matters Welcome to the internet’s nihilism crisis.

I wrote about something I've been thinking about for a long time. A kind of post-ironic collapse in our politics and culture where nihilism has become the lingua franca of the internet and beyond. It links Kirk, Clavicular, Epstein, memestock/coin stuff, mass shooters. I hope you'll read it.

This is what it looks like when non-violence is *working.*

You willingly experience violence because in committing violence the regime delegitimizes itself in the eyes of people who had previously supported it.

What is your reaction to Donald Trump saying, β€œI pray and hope that 2026 will be the year that we make Iran great again” and his pledge to strike Iran if protesters are killed, which they have been? Do you fear U.S. intervention in Iran?
This regime has fallen already. And, as I have said before, the people who are carrying out the protests in the streets, they want to make that happen. Of course, international support can make a difference. But until people themselves decide to do something or not, nothing is going to happen. Nothing is going to make any difference. It has to come within, from within the country, by the will of people.

So you do not feel the need for U.S. intervention in Iran. Correct?
You do not seem to understand. Let me say it again: Until people have the will to change something from within, nothing will be able to make that change. It has to be by the will of the people from within.

You have repeatedly stated your desire and resolution to return to Iran as soon as your activities related to the promotion of this film allow you to do that. But given the escalating violence against protesters and dissidents in your country, and also given the fact that you have been given a prison sentence, are you having second thoughts?
These developments make absolutely no difference in my decision. As I also said during my interviews in Cannes, it doesn’t matter what will happen to me as a result of this film: I have to go back to Iran. And I did go back to Iran [after Cannes]. I am the kind of person who needs to be in his country. I need to breathe there and work there. And even if they want to go ahead with that prison sentence, they can go ahead. Nothing will change my mind about going back.

The real question is: why wouldn’t we want to stay in Iran? Why should it be us, the people, leaving?Whereas it is the regime and its representatives that seem entitled to stay there. We are entitled to our own country. It’s the regime that has to leave and go. Because it has fallen.

Austin faces new high-stakes decision on paying for parks over I-35 The Austin City Council is being asked to choose deck locations by May with less cost certainty β€” or waiting and facing higher prices.

Which parks decks over I-35 should the city commit to paying for? The price for all 14+ acres exceeds $300 million.

TxDOT says they only need a ballpark estimate from staff by May. City staff say they can't give an estimate without a council vote.
