I am a sucker for good books, and so especially O'Reilly books. Here's one that is WIP, but in return, it is free, thanks to @antithesis.com It's for CTOs / eng leaders who want to get AI to deliver *business value* which is... tricky. Get it here: pages.antithesis.com/oreilly-scal...

I'm glad that the slowdown of AI development finished today with the release of Opus 5.5 and GPT-6 Sol and Luna! Now that all the safety issues are fixed, we can continue to move forward!

Serverless hosting of coding agent sessions and web apps. I decided that using EU regions on fly.io might be good enough to get started. When demand is proven, I can start renting bare metal machines from Scaleway and run Firecracker myself.

Excellent piece by @seldo.com I’ve noted some connections on Semble: semble.so/url?id=https... imo protective, ‘fair source’ licensing applied sparingly is perfectly compatible with commercialized registries and helps draw clearer boundaries where there currently are none.

Ink & Switch's approach of being forward-looking while staying uncompromising on both the value of intention in what you make and the necessity of shaping the world to match your and your community'´s system of values is (in my opinion) the most essential message in software right now
A quote from Peter van Hardenberg, the lab director of Ink & Switch, from his talk "How to Research Tools for Thought":

"I would encourage everybody to think about how – as we're moving through this new world – that we are intentional about how we shape it. And I don't want to tell you whether you should or shouldn't adopt any particular technology, but I will tell you that the world will not wait for us – and that we need to figure out how we can engage with our values and our intentions, and how we can serve our communities to make sure that the people who are using these tools that we build and that other people build are able to do them in safe and trustworthy ways, but also in ways that are satisfying and joyful and let us have what we set out to do."

Screenshot of the commit-rewriter web interface. A heading reads commit-rewriter above the repository path and current branch and commit hash, with a short description of the tool. A toolbar shows a pending edits count with Discard drafts and Rewrite commit messages buttons, followed by a search box for message, author, or hash and an Edited only checkbox. A left sidebar titled Navigate commits lists recent commit messages with their short hashes. The main panel shows a card for each commit with its hash, author and timestamp, an editable text area containing the commit message, and a View full formatted diff toggle.

ctrl+F "china", yup, it's the usual dario dementia, close tab. nothing of value there. he's not urging a "slowdown", he's spinning a story to lure you into reading his sinophobic manifesto about how everyone needs to "keep [US]’ AI lead over [China] as large as possible" or the world ends.
Pacing within democracies will be limited by the lead that US companies have over authoritarian regimes, chiefly the Chinese Communist Party. If we slow down by more than this amount, then (unpaced) CCP-associated projects will pull ahead, creating significant national security risk. I agree with Secretary Bessent that a Chinese lead in AI would pose grave danger for the United States and the world. The CCP-associated projects will run the alignment risks that US companies are carefully preventing, and even if they avoid those risks, they will be in a position to militarily dominate democracies (for example with AI-driven drones). Thus, a key part of pacing within democracies is to keep democracies’ AI lead over autocracies as large as possible, to give us the breathing room we need in order to pace effectively.

The main steps we can take to defend this gap are:

    Do not sell powerful AI chips or semiconductor manufacturing equipment to China, and crack down on chip smuggling operations and remote access to data centers outside China. Chips will be the main determinant of China’s AI strength.
    Crack down on unauthorized distillation by companies in authoritarian countries. Distillation of frontier models allows lagging companies to narrow the gap using a fraction of the cost it would take to develop their own AI independently.
    Strengthen security at the AI companies and prevent model weight theft.

Companies and the US government should cooperate to make these steps as effective as possible. Anthropic has consistently advocated for all of these measures, because we’ve always understood that they would be essential to any pacing.
