I admit that I completely broke down today. I cried uncontrollably. I couldn’t hold myself together after witnessing what I saw with my own eyes. Today, we went to film a journalistic report inside the displacement tents along the seashore. I swear, what we witnessed was beyond what any human being should have to endure. I saw men crying bitterly. Men I had never seen cry when they lost their children or when their homes were destroyed. Today, I saw them crying because they were powerless to do the simplest thing: protect their children from the water and the cold. We spoke to families who told us they had spent the entire night carrying their children in their arms after floodwater covered the floors of their tents and soaked their mattresses. They couldn’t find a single dry place to put their children. They couldn’t even give them a few hours of sleep. I saw children no older than five, without proper clothes to protect them from the cold, without heating, and without a dry place to sleep. Children shivering inside tents that cannot keep out the rain, protect them from the wind, or provide even the most basic sense of safety. What more must happen for this world to act? How much more suffering must people endure before someone remembers that they are human beings? I am sick of this world. I am sick of its hypocrisy and empty slogans. To hell with a world that talks endlessly about human rights while leaving children to drown inside their tents. To hell with everyone who has witnessed this suffering and chosen silence, and to hell with the governments and institutions that have the power to act but continue to turn their backs on us.

The bug is like a joke. On Alpine Linux, type 257 to 1024 characters of anything and you get root. 💀

We got your back, New York!
Readers added context they thought people might want to know
Several figures here aren’t federal results or NY-specific. The $472B combines US wide pledges: Micron's $250B is nationwide (NY site $100B) Anthropic's $50B covers TX and NY. The 48% murder drop is from NY's state run GIVE program (28 departments, Jan – May 2026). arkolith.com/news/news-micr… therepublic.com/?p=843020 governor.ny.gov/news/safer-str…

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math. It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training. We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵 Blog: rikiyat.github.io/blog/weigh…
Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math. rikiyat.github.io/blog/weight-sp… github.com/RikiyaT/lm_und… huggingface.co/Qwen/Qwen3.5-0… huggingface.co/RikiyaT/Qwen3.…

Oxford Street's first traffic-free Friday night ❤️
Really quite tranquil and relaxing walking along Oxford Street and ducking underground to an abundance of tube trains We need to let more cities 1. Deliver their vision of streets alongside 2. Building metros and trams by 3. Allowing them to raise and spend funds locally

Introducing tiny.london A massive isometric pixel map of London, based on amazing NYC demo by @_coenen from 9 months ago My agent created the dataset, finetuned qwen image LoRA adapter, did a multiday inference run and built an efficient tile viewer!
I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code.

We’re committing a portion of Anthropic’s shares to the Anthropic Public Benefit Fund, a new wholly owned entity dedicated entirely to the public benefit. It will start off with 5% of our shares. For every 50% increase in the company’s value over a set baseline, we can contribute up to an extra 2%, subject to our board’s discretion. In total, this means that roughly 20% of Anthropic’s shares are committed to the public good. Our co-founders have already pledged to donate 80% of their equity, and around half our employees are donating a portion of their equity as part of a donation matching program we’ve run since our founding. In the post below, we share more details about our new fund. anthropic.com/news/public-be…

The battle of narratives is going strong. Our countries are a recurring target. It is time to act to tell the stories that make us strong. Let’s live our own story! Protect what matters - our democracy.

Today, Ukraine and Moldova take another step towards our Union. Negotiation clusters are now opened on internal market as well as competitiveness and inclusive growth. Ukraine’s and Moldova’s future is in our Union. And we will support them all along the way.

Mamdani: This afternoon, a New Yorker was shot by ICE agents. ICE agents surrounded the man's vehicle before opening fire. They wore construction vests and masks that concealed their faces. There was no reasonable way to way to identify them as JCE agents. School had just gotten out. The street was crowded with families and children. When ICE agents opened fire. A five year old child, a five year old child was in the car.

This is incredible
We’re releasing a broad range of new mathematical results produced by an internal frontier model. We’ve been consulting with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study, and we have drawn on their advice and public recommendations to inform how we release these results. github.com/openai/math
