Well gang, it's happened: OpenAI has built a platform filled exclusively with fake, AI content.

I've been playing with it for a few days, and I think it's safe to say we're basically kissing reality goodbye.

Here's the story: www.npr.org/2025/10/03/n...

As candidate for mayor of New York City, Mamdani must make his position on extending New START limits clear. His silence on minuteman upload is deafening.

Pope Leo rebukes climate skeptics after Trump calls warming a ‘con job’ The Illinois native’s comments come a week after the U.S. president derided the fight against climate change.

Pope Leo XIV denounced people who deny climate change today, arguing that they are contributing to the destruction of God's creation.

Seeking a New Moral Compass on Nuclear Weapons Aboard the Golden Rule A sailboat that symbolized anti-nuclear activism in the late 1950s has been restored as a reminder of the need for arms control.

“What the Golden Rule symbolizes is as relevant today as in 1958 when Bigelow and his crew set out from California for the first time.” Read UCS’s @dkspaulding.bsky.social reflections as a temporary crew member aboard the recently restored boat, a symbol of anti-nuclear resistance.

You wouldn’t think the cost of a fixed-price construction contract could increase—but hundreds of NNSA’s run over, to the tune of $37.5 million just in FY23. NNSA’s construction budget is always tight so unexpected increases mean delays for other projects. www.gao.gov/products/gao... #nukesky

NNSA spends a lot of money on nuclear weapons & infrastructure. NNSA has requirements (similar to those of the Nunn-McCurdy Act) to formally notify Congress about cost overruns and assess the reasons for the overruns, but it hasn’t consistently done so.

I recently had the privilege of crewing aboard a sailing vessel called the Golden Rule, a boat that was used to protest nuclear tests in the Pacific in 1958. This piece is a reflection on the anti-nuclear movement that the boat helped to start and a look at where we are today. Please check it out:

How to Make the Next Trump-Kim Meeting a Success Kim Jong Un could be willing to agree to a nuclear weapons-free zone in Northeast Asia because it would threat North Korea the same as China, Russia, and the United States.

“As unrealistic as the establishment of a nuclear weapons–free zone in Northeast Asia may seem, talking about it can be a vehicle for improving security in the region..” The latest from my colleague, @gkucs.bsky.social on prospects for a potential Trump-Kim reunion.

Atomic Bowl: Football at Ground Zero -- And Nuclear Peril Today | The Atomic Bowl: Football at Ground Zero -- And Nuclear Peril Today | AtomicBowl The U.S. all-star football game in the atomic ruins of Nagasaki--and why it matters today

This is a well done documentary that highlights oft-overlooked aspects of the US atomic bombings and diverges from the 'traditional' (often inaccurate) accounts that have descended from censored records and interpretations based on US exceptionalism which ignore the most callous aspects.

Trump's hope to 'take back' Bagram airbase dismissed by Taliban official Bagram airbase was handed over to the Afghan military shortly before the Taliban returned to power.

What I really want to know is what Trump heard, and from whom, that got processed and spit back out as "we need Bagram air base cause it's an hour from where China makes their nukes." www.bbc.com/news/article...

It’s Time to Rethink US Nuclear Weapons Manufacturing There is no technical justification for replacing the entire US nuclear arsenal—but the government is willing to spend more than $2 trillion to do just that.

The DOE has ordered a review of a key part of nuclear modernization - plutonium pit production. Here’s my take on why it (and plans for other parts of the US triad) deserve reconsideration and rescoping. At present, ambition and reality don’t align.

Even conservative thinktanks are projecting the cost of Golden Dome to be anywhere from $252 billion to $3.6 trillion over 20 years. Before the US commits itself to an unfeasible, easily defeated, false sense of security, it should be honest about the costs and capabilities.

Another good reminder that sophisticated defenses can be easily overwhelmed with very low-tech countermeasures. While this is air defense, proponents of missile defense would be wise to take note. The same truth applies.

There are no words for how stupid and unnecessarily destructive these charades are for international relations, the economy, and regional stability outside the US. The US used to be thought of as a bulwark against tyranny and instability. Now are are a catalyst.

I don't control the press releases, I just "say the stuff"... Statements like these are usually meant for journalists who are already covering the issue and, I agree, not very suitable for public consumption. I will pass along the feedback so that they might be made more digestible.

@tayloraloy.bsky.social Apologies for lack of context. I agree that given public concern, venting into another container would seem logical and I voiced that to NMED. LANL rejected that option because it results in additional waste. Given the obvious public concern, another FTWC seems better to me.

A Sacramento park plaque with a big mistake was finally removed. When will the park open? Although the park appeared ready to open this fall, it remains padlocked, with residents forlornly walking dogs around the perimeter.

There's also this, as well as his attempt to name streets in the new development with names like "America First Ave".

Pit production is on track to follow suit. The question is whether DOE will take the opportunity to identify what is actually achievable and on what timescales vs waiting for failure to cause parts of the current program to crumble on their own. Which will it be? Stay tuned... 🍿

Two previous examples: 1) The Mixed Oxide Fuel (MOX) facility at Savannah River, originally projected to cost ~$1.5B, was cancelled in 2018, by which time projected cost was $17B. 2) The Uranium Processing Facility at Oak Ridge, originally estimated to cost ~$600M, up to $11B by 2023.
