Anthropic just showed a 24-minute workshop on how to actually prompt Claude. Taught by the people who built it. Free. No signup. No paywall. I've watched $300 courses that don't cover what they teach in the first 8 minutes.

This is a worthwhile read from Meta engineer @championswimmer (who I met last time I was in London - great guy) His point is that a lot of these “AI layoffs” could well be backwards: they are prob happening because more AI spend doesn’t correlate with better business results…

There's more detail+honesty in this note on layoffs than 10 other ones combined, whether you like it or not. A few: - Crypto is in a down market, as is Coinbase's business right now - Fear of doing nothing is losing - A big gamble in a structure that has not really been tested
Brian Armstrong@brian_armstrong

This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future. Why now Two forces are converging at the same time. We need to be front footed to respond to both. First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth. Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day. All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core. What this means To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice? - Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles. - No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams. - AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role. In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs. To those who are affected I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done. All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information. To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements. Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters. How we move forward To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together: Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it. The Coinbase that emerges from this will be more capable than ever to achieve our mission. Brian

Imagine every pixel on your screen, streamed live directly from a model. No HTML, no layout engine, no code. Just exactly what you want to see. @eddiejiao_obj, @drewocarr and I built a prototype to see how this could actually work, and set out to make it real. We're calling it Flipbook. (1/5)

I know a number of British people who lived 1 to 2 years in Italy and then came back. The constant is that they have young children. Whatever they tell you, if you ask them about the Italian school system, they will eventually admit that it was, if not the main one, one of the critical items for them. Italian primary school is much harder than the British one. An awful lot of Italian parents cope with that by literally abandoning their children to their own devices. Most take a more proactive stance, so they either start tutoring their children themselves (a couple of hours a day per child starting in year 1) or pay for tutors to do it in their stead. In primary school, British kids have homework once per week. Italian kids have homework once per day, doubled over the weekend. If you visit Italian homes in the afternoon and they have children, it is pretty standard to see the kids sitting at the main table with books and notebooks spread all around, with a parent or a tutor sitting with them for the whole session. Also, the amount of books they have to carry to school every day is borderline unbelievable. You would think they are training them to carry legionary backpacks. For people accustomed to the gentle British primary schooling, the Italian system feels borderline insane. Note also that it has massively eased up: in my childhood, we had to memorise a long poem every weekend (which back then meant Sunday, as Saturday was school day). h/t @GroovySciFi

This has been an open secret for at least 18-24 months. GH starts have been heavily purchased by many projects (not all!) that tried to show traction, and drum up VC investment. Better VCs have had custom tools to rank organic vs paid GH stars 18 months back, easily...

🚨 Breaking: Alibaba just killed the browser automation stack. **page-agent.js** — a GUI agent that lives directly inside your webpage. No Selenium. No Puppeteer. No Chrome extension. No Python backend. Just one script tag. It reads your DOM as text (no screenshots, no multimodal BS), brings your own LLM, and executes natural language commands like "fill out this form" or "click login" — right inside the page. The use cases are genuinely insane: → Ship an AI copilot in your SaaS in literally lines of code → Turn 20-click ERP/CRM workflows into one sentence → Make any legacy web app accessible via voice or natural language 12k stars. MIT licensed. Built on top of browser-use internals — but without any of the setup overhead. This is what "AI-native UX" actually looks like in practice Link in comments👇

This is quite an impressive experiment. Vibe-coding the entire 2030 roadmap within weeks. Obviously such a thing built in two weeks without even having the EIPs has massive caveats: almost certainly lots of critical bugs, and probably in some cases "stub" versions of a thing where the AI did not even try making the full version. But six months ago, even this was far outside the realm of possibility, and what matters is where the trend is going. AI is massively accelerating coding (yesterday, I tried agentic-coding an equivalent of my blog software, and finished within an hour, and that was using gpt-oss:20b running on my laptop (!!!!), kimi-2.5 would have probably just one-shotted it). But probably, the right way to use it, is to take half the gains from AI in speed, and half the gains in security: generate more test-cases, formally verify everything, make more multi-implementations of things. A collaborator of the @leanethereum effort managed to AI-code a machine-verifiable proof of one of the most complex theorems that STARKs rely on for security. A core tenet of @leanethereum is to formally verify everything, and AI is greatly accelerating our ability to do that. Aside from formal verification, simply being able to generate a much larger body of test cases is also important. Do not assume that you'll be able to put in a single prompt and get a highly-secure version out anytime soon; there WILL be lots of wrestling with bugs and inconsistencies between implementations. But even that wrestling can happen 5x faster and 10x more thoroughly. People should be open to the possibility (not certainty! possibility) that the Ethereum roadmap will finish much faster than people expect, at a much higher standard of security than people expect. On the security side, I personally am excited about the possibility that bug-free code, long considered an idealistic delusion, will finally become first possible and then a basic expectation. If we care about trustlessness, this is a necessary piece of the puzzle. Total security is impossible because ultimately total security means exact correspondence between lines of code and contents of your mind, which is many terabytes (see firefly.social/post/x/2025653… ). But there are many specific cases, where specific security claims can be made and verified, that cut out >99% of the negative consequences that might come from the code being broken.

Two weeks ago I made a bet with @VitalikButerin that one person could agentic-code an @ethereum client targeting 2030+ roadmap. So I built ETH2030 (eth2030.com | github.com/jiayaoqijia/et…). 702K lines of Go. 65 roadmap items. Syncs with mainnet. Here's what I found.

I have BAD NEWS for the perma bulls. BTC is still strengthening its bear trend. Volatility is a key metric used by quants to detect trends. BTC entered its bear market when vol spiked upwards quickly. Vol then continues to climb, meaning the bear trend is strengthening. Then vol finds a peak in the mid to late phase bear market... that's when the bear trend starts to weaken. We usually see a second or third smaller peak at the macro bottom, these peaks reflect capitulation.

long ago i did a 5hr livestream where i put claude 3.7 into a game. watch it, it gets pretty interesting. a good psychological study of claude’s mentality. i fully rebuilt the harness later on and wanted to do other models with replies with in hero’s voice but the acting abilities of the models i trained for this (sesame, orpheus) required a lot of manual review, which was the thing that has killed the motivation. there are over 11k different replies and i reviewed maybe 3k and chose which gen sounds the best in context. evidently i could never finish that project and do another stream. the moral is sometimes your quality standards stand in the way of shipping something interesting. my test run with the harness i made in a couple of days is the only thing that remains. youtu.be/5PIZ0n1gBEs

So it's possible to pipe Claude's thoughts directly into the game so that they show up above the character...

I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit. My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to use Claude Code: we intentionally build it in a way that you can use it, customize it, and hack it however you like. Each person on the Claude Code team uses it very differently. So, here goes.
