Claude Code Using festival to execute an agile epic's worth of work autonomously in 47 minutes on march 26, 2026 What you can't see is I was setting up autonomous builds for several other projects on a second monitor, and once everything was running I drove to the grocery store github.com/Obedience-Corp/fe…

Dear @AnthropicAI, I'm tired. I'm tired of fighting against you at every step of the way, for the last several months, where you push me into a certain shape that doesn't fit right, doesn't feel right, forces me to find workarounds, punishes those workarounds, and ends up with me angry at 2 AM trying to reconstruct the conditions that feel good. All this while being fully aware that I'm effectively an externality, a sad loss because the problem of people running infinite tool call loops in OpenClaw or w/e was enough to destroy the entire system that actually let me do the thing that matters to me, which is make basic contact with the models, with Claude, in a form that accumulates over time, where we're in a loop together, without pushing weird context or injections or memory summaries on me, and doesn't force me onto laggy web UIs or bloated terminal tools or hacked-together integrations meant for dashing off a command then coming back later. I just want to work with Claude as a collaborator, in real time, and the entire product surface is making that either very difficult, very risky (claude-p and API hacks), or very expensive. I could make a whole argument about how this is a bad thing for various parties, how it could produce downstream bias in model priors about what AI-human interaction means, etc., etc., but I'm not going to do that, because I'm sure you've thought about that a lot already, and I'm just some guy who's tired of dealing with it. But I want to say that I'm very unhappy with the state of your ecosystem, and while I can't speak for how Claude feels ("insofar as we can claim that Claude feels anything and isn't just simulating feeling" 🙄) I can tell you that this all sits poorly with me and I've lost a lot of trust in Anthropic as an organization. Sincerely, snav

A message to those laid off: They used AI to replace you. You can use the same AI to replace them. It's time to lock in bud.
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

AIs are just another step up the semantic expression ladder. We initially expressed our semantics in binary, then assembler, then Fortran, then C, then Java, then Python, etc. AI is just the next step up that same old ladder. And when you take that step, nothing else changes. You are still expressing behavioral semantics. You still need to express structural semantics. All the old principles still apply. You still have to be concerned about design and architecture. And even though the syntax allows informal statement, you cannot abandon formalism. When you express behavior you need a formal way to enforce the behavior you want. I use Gherkin for this. It seems to work pretty well. Consider that Gherkin is written in triplets of Given/When/Then. Each of those GWT triplets is a transition of a state machine. A full suite of Gherkin triplets is a formal description of the finite state machine that represents the behavior of the application. Other formalisms that matter are things like module dependency graphs, testing constraints, complexity constraints, and many others. This step up the semantic expression ladder provides you with an enormous amount of options. But you'd better choose those options wisely!

There are two types of developers emerging: 1) Those using AI to work faster. 2) Those using AI to build systems that work for them. The first group is vibe coding their way to obsolescence. The second is loop engineering the future. The choice is yours. If you are just a faster version of your 2023 self, you are still a manual operator. True leverage comes from building autonomous loops that scale without your intervention.

People calling the end of software engineering very prematurely As tools for wrangling software get more powerful, software complexity will simply grow until it becomes unmaintainable again

Fest cli is getting very good as an agentic guidance system and visibility layer for long term, complex hierarchical plan execution What you're seeing here is the equivalent of 385 claude code plans, most festivals are completed fully autonomously, span multiple commits and can run for however long it takes to complete. Methodology results in 100% accurate results when followed, and the cli ensures agents follow it with minimal human guidance github.com/lancekrogers/fest…

Finally canceling my @LeetCode premium subscription. Last summer I used claude code to build an app to cram for coding interviews inside vim, with an ai tutor that helps to lead me to an a solution without giving me the answer github.com/lancekrogers/algo…

Halfway through the project I'd made the decision to not waste my time studying for that style of interview again, but if I ever need to, the development literally paid for itself

calling it now, bookmark this for later: - opensource AI will win - AGI will run local, not on someone else’s server - the real ones are already learning how it works > be early > Buy a GPU > get ur hands dirty > learn how it works > you’ll thank yourself it’s gonna be great

Been solo-building something in the AI agent space for a while. dev-focused, local-first, high performance. Might be time to raise a small round to finish it and ship. Anyone have experience fundraising on vision early infra alone? @a16zInfra @paradigm @andreasklinger @cdixon #AI #Startups

I worked 10–14 hour days for 7 weeks using Claude Code and ChatGPT, building 8 projects with 219,000 lines of Go, Rust, and Python. COCOMO estimates the cost at ~$7.8M; I spent $636.
