We built a replacement for AWS DynamoDB, a key-value database for fast web content fetches. This was done with two engineers and hundreds of persistent Computer agents over two months. Migrating to our in-house database will save us up to a hundred million dollars yearly.
BREAKING: A New York firefighter directly confronts a group of Nazis and Pro-Palestinians who teamed up to protest the 9/11 memorial.
“Go back to f*cking Palestine.”
Researchers spent 500 hours and $70,000 and found LG TVs logging plain text transcripts in standby, mapping every device in the house, and feeding it to LG's ad arm
Unplug the internet and it saves the files until you plug back in.
LG says its TVs don't record ambient conversations.
The evidence begs to differ.
216 million of these are sitting in living rooms.
Where are the regulators?

Harnesses often get dismissed as just scaffolding, just prompt engineering, and not real research. But that couldn't be farther from the truth. The same model weights that score 30% on ARC-AGI score 95% with a better harness.
So we gathered a group of researchers and founders working at the frontier to do a deep dive into the state of harnesses.
We cover how we got to this point, the case for making your harness as expressive as possible, and what YC learned building an agent for every employee in the company.

this is a critically important moment for cyber defense with AI; there is not much time to act.
we are happy if you want to work with us or any of our competitors or partners, but please take this moment seriously.
only an urgent and intense collective response will work.
🚨🇺🇸 BREAKING: Marine One flew within 0.8 miles of a passenger jet over Washington after the tower couldn't hear the president's crew.
-The helicopter carrying Trump came within 0.8 miles laterally and 700 feet vertically of an Envoy Air flight Tuesday afternoon, per two people familiar with the FAA's preliminary findings
-The FAA defines a loss of separation as breaching 1.5 miles laterally or 500 feet vertically, so that lateral gap was well inside the line
-The cause was radio failure: Marine One's crew tried THREE times to warn National Airport's tower it was three minutes from lifting, and a controller replied that the call was "broken" and "unreadable"
-They took off anyway, straight into the path of a jet that had just departed for Pensacola, and the controller sounded surprised when the helicopter radioed that it was "proceeding as briefed"
-The White House says Trump "was at no point in harm's way," and the FAA calls it a "momentary loss of separation" with a review ongoing
-Trump has been flying out of the Ellipse since July while a new helipad is built on the South Lawn, adding a new variable to some of the most congested airspace in the country
Now sit with this.
In January 2025, an Army Black Hawk hit an American Airlines jet in this exact airspace and killed all 67 people aboard.
The NTSB found degraded radio reception left that crew blind to the plane it struck.
Eighteen months later, a helicopter carrying the President of the United States lifted off into traffic because the tower couldn't hear him either, and many of the fixes the NTSB demanded still haven't been made.
Think about the month this man has had.
A $10 million militia bounty on his head.
Iranian state media publishing a video mapping his and his wife's shopping routes and ending with a threat to his son.
A plane swap out of Turkey over fears of an assassination plot.
A heavily armed man arrested at his golf course Sunday with body armor and notebooks.
And now the aircraft that carries him nearly clips an airliner because a radio didn't work.

SENATOR CRUZ: Does the Muslim Brotherhood also partner with the Democratic Socialists of America?
COUNTERTERRORISM ANALYST: Yes sir they do.
Welp… there you have it.
I spent my life hunting terrorists. I never in a million years thought I’d hear the words, “America deserved 9/11,” but here we are.
Michigan — we’ve got a state to save.
Some more detail on the ROIC Intelligence App I built yesterday and mentioned on today's earnings call.
I took the PDF that Brian Nowak at Morgan Stanley put together for Hyperscale ROIC this week and used Copilot code (coming in our new superapp) with a single prompt + skill (/drill-me) to create the plan, then used autopilot in auto to create the full app (with history, lookups, scenarios, what-ifs, etc). And /rubber-duck to test.
And the best part is that all the artifacts are in my enterprise environment. My app is in Copilot, my code is in GitHub Enterprise; all my data pipelines/lake/semantic models are in Fabric. And everything is under Agent 365 IT/Sec/FinOps control!
So this is not about Tokenmaxxing or vibe coding. Every step of the way the rails are engineered to create value, making everything a long-term reusable asset, with governance/security, and cost controls.
This is the full system to drive business value. Disclosures: This is all pulled from public sources, and for illustrative purposes only...not financial advice! :)
Here is the app and architecture...
Attackers have frontier AI. Defenders need a frontier AI ecosystem—the best open and closed models, force-multiplied by a global community.
During the Hugging Face incident, closed AI blocked essential forensics. An open-weight frontier model helped contain the intrusion.
That’s why we created the Open Secure AI Alliance.
