U.S. Troops Were Told Iran War Is for “Armageddon,” Return of Jesus Advocacy group reports commanders giving similar messages at more than 30 installations in every branch of the military

The good news is that if we lose in Iran and create horror across the region then Jesus comes back and fixes everything. Hegseth Doctrine.

Perhaps not Boring Technology after all A recurring concern I’ve seen regarding LLMs for programming is that they will push our technology choices towards the tools that are best represented in their training data, making it …

A short note that the predictions that LLMs would favor "boring technology" that's over-represented in the training data don't appear to be playing out as expected with the latest models - once you attach them to a good coding agent harness at least simonwillison.net/2026/Mar/9/n...

The best part of growing up when I did was all of the really cool John Williams music videos.

I’ve always been a Firefly fanatic, but I also have always found the two boys’… thirst to be off-putting. The Instagram sketch is only a little bit fun. I guess I’m broken.

The Desire for Terror And the defense of democracy

A purpose of the war on Iran might well be to provoke a terrorist attack inside the United States. This would provide Donald Trump with a pretext to try to cancel or “federalize” the coming Congressional elections.

A young barmaid behind the bar at the famous French nightclub Folies-Bergère is staring forward in a bored, introspective way.  Behind her is a mirror which reflects the lively scene.  At the top left you see the green shoes of a trapeze artists.  More importantly, at right you see the back of the barmaid, and see that she is face to a man who leans close and seems to be requesting something.

This is Manet's famous painting "A Bar at the Folies-Bergère":

The perspective looks all wrong. You're staring straight at this barmaid, but her reflection in the mirror is way off to right. Even worse, her reflection is facing a guy who doesn't appear in the main view!

But in 2000, a researcher showed this perspective is actually possible!

What Does Russia Have on Trump? Americans Deserve an Answer As Russia reportedly shares intelligence with Iran that could endanger American forces, the White House chooses to ease pressure on Moscow instead of confronting it.

Ukraine offers to help defend the West from Iranian drones.

Russia helps Iran track American forces.

And the White House eases sanctions on Russian oil.

Explain that to the families of U.S. troops. My latest:

Atari 8-bit Fugue
Atari 8-bit Fugue YouTube video by Greg Langmead

I got this out of my head! On our Atari 800 my parents typed in a program that played a Bach fugue. I couldn't find a video, so I made one by finding the BASIC listing and getting that working in the Atari800MacX emulator. It's from January 1981, so I was 7.

What if? Are you or I the enforcer of consistency? One moves on. They are our exact equal, out there being wrong like we all are. It's the idea that this needs to be *fought* that turns my earlier interlocutors into trolls.

Of course not. But a citizen who wants gun control who doesn't know what AR stands for is in perfectly fine alignment. They are not undermined even 1%.

Dismissing the concerns of anyone you can undermine the expertise of. If you don't know what a bump stock is, or what AR stands for, you are a gun grabber lol. It parallels the discourse of the toxic folks who believe they *understand* the tech better, hence have hierarchically better opinions.

And if you willingly conflate the CS term "semantics" (what a program does) with the term I am obviously using (the intent of a human communication, which refers to things in the world), then you have presumed your conclusion.

Wow, there truly are GenAI versions of the second amendment people out here. Like we don't all know that semantics has multiple meanings, one of which is about meaning and one of which is merely "what a program does." What an ugly bad-faith part of the discourse you are.

04.03.2026 11:56 👍 0 🔁 0 💬 0 📌 0

Yep, snark-haver. It's unambiguous tokens built by rules. CS overloads the term "semantics" for "what it does", but I'm using the real original meaning of the word: language that refers something out here in the human world.

Straw man. It's good at the coding case because code lacks semantics. Looks like this was a situation where it needed to write a bunch of programs. The lofty claim that was *actually* being refuted since the early days was that it's truly semantic with language. It ain't.

If the agents want to prove their worth, they should find every discussion thread on the internet that lacks a correct answer, log in, and post the answer.

Super cool. I've become allergic to the agentspeak phrase "key insight." To me insight is super rare and not very likely to exist on any given day. But the agents toss it around like easy stuff is hard! That's neither here nor there, ignore me.

How will OpenAI compete? — Benedict Evans OpenAI has some big questions. It doesn’t have unique tech. It has a big user base, but with limited engagement and stickiness and no network effect. The incumbents have matched the tech and are lever...

I'm very pleased that people are using OpenAI's products so little, it speaks highly of humanity. I am bullish on coding agents, but of course that's not the unicorn they are chasing. These are not products, they are mere features.

No one who is at all concerned with the national security of the United States can possibly support Trump. This is simply a hideous betrayal of the country and its future in exchange for a bribe.
