YES! It's out it's out, I am SO excited for this! #AWSLambda Web Functions are a game changer! A true HTTP request handler and Each execution environment handles multiple requests simultaneously (up to 128 concurrent requests per environment). Multi-region deploy, and so much more! -> aws.amazon.com/blogs/aws/ann…

Introducing ChatGPT for Dishwashing GPT-6 achieves state-of-the-art results on dishwashing benchmarks for long-running jobs and difficult stains. The Navier–Stokes Millennium Prize Problem is a $1 million challenge about whether the equations describing fluid motion can break down. In this video, I accidentally found a counter-example while trying to optimize my dishwasher. But in reality, OpenAI used 10,000 AI agents to find a proof in 88 hours: openai.com/index/navier-stok… Parody of the original GPT-6 Astra ad @OpenAI #ChatGPT_Partner #chatgpt Credits: Written and Directed by Joma Co-Writer - Henry Connor Coan IV @coan_henry Production by Dauntlus Studios @dauntlus.studios Producer/Co-Director - Marcus Liew @dauntlus Camera Operator - Amos Lee @amoselijahlee Art Director - Alethea Soo @aletheasoo Art Assistant - Alicia Lim @aliciatkl_ Assistant Editor - GPT-6 Astra Music: Tensions Run High by Soundridemusic youtube.com/watch?v=Ly9H63SL…

I stand by this even more following Ed Sheeran's weak bs post today. 10 years ago I was the centrist fence-sitting final boss. I get it Ed. I thought it made me enlightened, but looking back it was just cowardice. Too many things are too fucked rn to stay silent or neutral.
Philip DeFranco CALLS OUT Ed Sheeran: Saying I don't take sides, that feels like an insane thing to say when scholars who cover genocide call it a genocide The conflating of just criticisms of Netanyahu and Israel to actual anti-Semitism gives cover to the actual anti-Semites

here we go again, the top 4 red flags: 1) A\ started the race, but don't worry, the one they started is "a race to the top" (not bottom, you cynical meanie) 2) pacing doesn't actually mean stopping model training or anything amongst the current players, just adding more eval time (disingenuous ladder pull, imo, but sure yeah a third-party-eval-spy-fest seems nice!) 3) limit the access to ingredients that go into frontier models, but this notably does not include limiting access to raw data, or their stash of burned books (copyright is so beyond dead lmao) 4) pace by limiting chips and "unauthorized distillation" (still embarrassing that these AGI systems can't stop their own distillation but sure why not hammer in the red scare rhetoric some more) anyway, earnest messaging, despite all the gaslighting. hope humanity doesn't go extinct after the IPO!
We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so. Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our systems, so that they can verify adherence to our safety measures, report on incidents, and assess models’ alignment during training.

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter. AI will transform every industry, power every company, and be built by every country. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. The world needs both frontier closed models and frontier open models. images.nvidia.com/pdf/Open-W…

Starting in early 2025, Elon Musk and the Trump administration began terminating USAID's programs and firing its staff — with Musk himself boasting about "feeding it into the woodchipper." One year ago today, USAID was officially dissolved, its remaining programs haphazardly folded into the State Department. Amid all the lies and misinformation that have followed, some facts about what has actually been lost: • USAID saved more than 3 million lives a year at a cost of less than $10/month per American. That is what was destroyed. On purpose. • According to Boston University's Global Impact Counter — which tracked deaths attributable to the cuts until it stopped operations in February 2026 — an estimated 781,000 people died preventable deaths in the first year, including 518,000 children. • Global child mortality (the number of children who die before their fifth birthday) rose in 2025 for the first time in 35+ years — by 200,000 additional deaths. • USAID's 50-country disease surveillance network — the system that cut outbreak response times from 2 weeks to 48 hours — is gone. We are now watching an unprecedented Ebola outbreak unfold in real time — with the highest first-month caseload and death rate in modern history. • Programs reaching 93 million women and children were cut 92%. TB programs cut 56%. Water and sanitation cut 86%. Over 2,000 health facilities permanently closed. • 25 million fewer people received humanitarian assistance in 2025. The overall humanitarian budget was slashed 74% — from $14.1 billion to $3.7 billion. • 363 million people face acute hunger in 2026. The famine early-warning system that would have seen it coming went dark for five months. • $1.7 billion in democracy and governance funding (election monitoring, anti-corruption work, support for independent media and civil society) was terminated. • 360+ independent media outlets lost funding. Hundreds of legal clinics closed. • Far from saving money, the Trump administration itself has already said the dismantlement will cost taxpayers at least $19.2 billion in cancellation fees, severance, and penalties. That's more than half of USAID's annual budget — spent on destruction and closeout, not support for vulnerable people. • American farmers, universities, and businesses are among the casualties too. USAID partnered with more than 3,500 U.S. companies and maintained 17 university-based research labs. Its work with U.S.-based contractors and the private sector generated hundreds of thousands of American jobs and multiplied the return on every dollar spent. Those markets and partnerships are gone.

Google removed my article about the shameful collapse of events tech company Pollen (employees lied to by CEO Callum Negus-Fancey, salaries unpaid, a seemingly deliberate $3.2M customer double charge manually initiated by CTO Brad Wright). Google decied that "Ellie Piee" claiming to live in this uninhabited island (the Bouvet Islands, zero inhabitants) claiming that my article is the exact copy of a 1998 New Yorker article (not even a sentence shared!) is credible evidence to remove my investigation about Pollen from its search results. I wrote up a new article about it: blog.pragmaticengineer.com/p…

just never forget that the devs who yap about AI being the best thing ever all day never really knew how to program well to begin with. They are idiots telling you that the world is solved (charitable read) or worse, they are selling you something and are attempt to deceive you. This is why we see the same cycle every time. Opus 4 = God's gift to humanity to OMG its utter trash within a few months. The same thing happens with every model release because these people don't even know what dev is. They are larpers. I believe this is what Geohotz meant when he: "I’m calling it now, the adoption of AI agents into software development will be one of the most costly mistakes in the field’s history."
All the devs whining about fable being banned need to go hit the gym and stfu

We all knew these situations were going to happen, and so did FIFA. Yet they still allowed the World Cup to go ahead in the U.S. They are not receiving anywhere near the level of scrutiny they should.
The United States has denied a visa for Iran's national team manager Mehdi Mohammadnabi. He will be barred entering the U.S. for their the Fifa #WorldCup 2026 matches. He & others also denied visas will travel to the team camp in Mexico whilst efforts to obtain visas continue.

You know why I don’t buy the “everyone will build their own software” take? I can build this. I have the tools. I know how (probably). But I don't want to. I want someone else to to build it maintain it, and charge me for it.
I want the following in Codex, Cursor, and OpenCode... 1. Pinned Messages: Let me pin assistant messages to the sidebar for things I want to keep track of but am not ready to address yet. Render as a checklist & jump navigation. 2. Notes: Give me a scratchpad for thoughts while working.

Today marks Nakba Day, an annual day of remembrance to commemorate the expulsion of more than 700,000 Palestinians between 1947 and 1949 during the creation of the State of Israel and the year that followed. Inea is a New Yorker and a Nakba survivor. She shared her story with us — one of home, tradition and memory over generations.

I find myself doing a lot better work, being more satisfied, and also learn a lot more+faster when I do *the hard work* and don’t outsource it to AI. As in, I’ll use AI as a *tool* with substasks, additional research: but I don’t turn off my brain or kick back, assuming it can do the work for me. Every time I “hand over the” hard work part to AI and mentally turn off, I either regret it or find myself eventually needing to go back and spend more time on it. I also see slop work coming out from people who assume the AI does better work than they would.

Sentry Act 2: no layoffs, no axing random vendors (unless they suck obv), continued investment into AI and doing what we always do imo its weak leadership to keep pushing out the same junk PR blaming random things vs saying what you're actually doing
