Building a Mac app with Claude code

I recently shipped Context, a native macOS app for debugging MCP servers. The goal was to build a useful developer tool that feels at home on the platform, powered by Apple's SwiftUI framework. I've been building software for the Mac since 2008, but this time was different: Context was almost 100% built by Claude Code1. There is still skill and iteration involved in helping Claude build software, but of the 20,000 lines of code in this project, I estimate that I wrote less than 1,000 lines by ha

Rocket Report: Japan’s workhorse booster takes a bow; you can invest in SpaceX now

Welcome to Edition 8.01 of the Rocket Report! Today's edition will be a little shorter than normal because, for one day only, we celebrate fake rockets—fireworks—rather than the real thing. For our American readers, we hope you have a splendid Fourth of July holiday weekend. For our non-American readers, you may be wondering what the heck is happening in our country right now. Alas, making sense of <waves hands> all this is beyond the scope of this humble little newsletter. As always, we welcom

Tesla Gets Dismal Sales News After Disastrous Robotaxi Launch

Tesla has posted its second quarter delivery numbers — and they're not looking good. As the New York Times reports, the company reported it had delivered just 384,000 vehicles between April and June, a massive drop from 444,000 vehicles over the same period last year. Meanwhile, CEO Elon Musk has focused his carmaker's resources on developing a robotaxi network of fully autonomous vehicles. However, given a disastrous launch filled with near-collisions, bizarre driving behavior, and human "saf

Mandelbrot in x86 Assembly by Claude

Mandelbrot in x86 assembly by Claude. Inspired by a tweet asking if Claude knew x86 assembly, I decided to run a bit of an experiment. I prompted Claude Sonnet 4: Write me an ascii art mandelbrot fractal generator in x86 assembly And got back code that looked... like assembly code I guess? So I copied some jargon out of that response and asked: I have some code written for x86-64 assembly using NASM syntax, targeting Linux (using system calls for output). How can I run that on my Mac? That

Building a Personal AI Factory

Anthropic Let an AI Agent Run a Small Shop and the Result Was Unintentionally Hilarious

Anthropic ran an experiment where its Claude chatbot was put in charge of a tiny, automated "shop" inside its San Francisco headquarters — and the results were nothing short of hilarious. Despite claims in an Anthropic post that "Claudius," the name given to the AI agent in charge of stocking the shop's shelves, was "close to success," everything about the gambit seems to demonstrate just how bad AI is at managing things in the real world. Dubbed "Project Vend," the month-long experiment was u

Joby Aviation stock pops 14% after delivering first flying taxi to UAE

An electric air taxi by Joby Aviation flies near the Downtown Manhattan Heliport in Manhattan, New York City, U.S., November 12, 2023. Joby Aviation stock soared about 14% as the flying air taxi maker got closer to launching a service in the United Arab Emirates. The electric vertical takeoff and landing, or eVTOL, company said Monday that it delivered its first aircraft to the UAE and has completed piloted flight tests as it readies for a 2026 launch in the region.

NASA will start livestreaming content on Netflix later this summer

This should be a convenient way to watch rocket launches and spacewalks. NASA is bringing live NASA+ programming to Netflix. For the uninitiated, NASA+ is the space agency's very own streaming platform. Content will begin showing up later this summer. This will be reserved for live events, with NASA saying it'll be used to stream "rocket launches, astronaut spacewalks, mission coverage and breathtaking live views of Earth from the International Space Station." NASA+ also streams original docum

What happened when Anthropic's Claude AI ran a small shop for a month (spoiler: it got weird)

Daniel Grizelj/Getty Images Large language models (LLMs) handle many tasks well -- but at least for the time being, running a small business doesn't seem to be one of them. On Friday, AI startup Anthropic published the results of "Project Vend," an internal experiment in which the company's Claude chatbot was asked to manage an automated vending machine service for about a month. Launched in partnership with AI safety evaluation company Andon Labs, the project aimed to get a clearer sense of h

Anthropic's Claude stocked a fridge with metal cubes when it was put in charge of a snacks business

If you're worried your local bodega or convivence store may soon be replaced by an AI storefront, you can rest easy — at least for the time being. Anthropic recently concluded an experiment, dubbed Project Vend, that saw the company task an offshoot of its Claude chatbot with running a refreshments business out of its San Francisco office at a profit, and things went about as well as you would expect. The agent, named Claudius to differentiate it from Anthropic's regular chatbot, not only made s

The second launch of New Glenn will aim for Mars

Blue Origin is making steady progress toward the second launch of its New Glenn rocket, which could occur sometime this fall. The company already ignited the second stage of this rocket, in a pre-launch test, in April. And two sources say the first stage for this launch is in the final stages of preparation at the company's facilities in Cape Canaveral, Florida. Publicly, the company has said this second launch will take place no earlier than August 15. This is now off the table. One source to

So you want to serialize some DER?

So you want to serialize some DER? (Editor’s Note: My day job is at Anthropic.) This story starts where all good stories start, with ASN.1. ASN.1 is… I guess you’d call it a meta-serialization format? It’s a syntax for describing data abstractly (a notation, you might say), and then there’s a bunch of different actual encodings that you can use to turn data into bytes. There’s only one encoding I choose to acknowledge, which is DER (the Distinguished Encoding Representation, it’s got a monocle

NASA Continues Testing Multi-Billion Dollar Rocket While Trump Is Actively Trying to Cancel It

Despite president Donald Trump's plans to phase out Boeing's mega-expensive Space Launch System rocket for NASA, the agency is currently trundling ahead with the original plan. As Ars Technica reports, NASA and Northup Grumman tested an experimental hydrogen-based propulsion engine this week that's slated to launch the world's first crewed trip to the Moon as part of the agency's long-awaited Artemis mission. Unfortunately, this week's SLS engine test — the second such test launch in a week —

Anthropic’s Claude AI became a terrible business owner in experiment that got ‘weird’

For those of you wondering if AI agents can truly replace human workers, do yourself a favor and read the blog post that documents Anthropic’s “Project Vend.” Researchers at Anthropic and AI safety company Andon Labs put an instance of Claude Sonnet 3.7 in charge of an office vending machine, with a mission to make a profit. And, like an episode of “The Office,” hilarity ensued. They named the AI agent Claudius, equipped it with a web browser capable of placing product orders and an email addr

Anthropic says Claude helps emotionally support users - we're not convinced

Richard Drury/Getty Images More and more, in the midst of a loneliness epidemic and structural barriers to mental health support, people are turning to AI chatbots for everything from career coaching to romance. Anthropic's latest study indicates its chatbot, Claude, is handling that well -- but some experts aren't convinced.

OpenAI’s Unreleased AGI Paper Could Complicate Microsoft Negotiations

A small clause inside OpenAI’s contract with Microsoft, once considered a distant hypothetical, has now become a flashpoint in one of the biggest partnerships in tech. The clause states that if OpenAI’s board ever declares it has developed artificial general intelligence (AGI), it would limit Microsoft’s contracted access to the startup’s future technologies. Microsoft, which has invested more than $13 billion in OpenAI, is now reportedly pushing for the removal of the clause and is considering

Project Vend: Can Claude run a small shop? (And why does that matter?)

We let Claude manage an automated store in our office as a small business for about a month. We learned a lot from how close it was to success—and the curious ways that it failed—about the plausible, strange, not-too-distant future in which AI models are autonomously running things in the real economy. Anthropic partnered with Andon Labs, an AI safety evaluation company, to have Claude Sonnet 3.7 operate a small, automated store in the Anthropic office in San Francisco. Here is an excerpt of

Rocket Report: SpaceX’s dustup on the border; Northrop has a nozzle problem

Welcome to Edition 7.50 of the Rocket Report! We're nearly halfway through the year, and it seems like a good time to look back on the past six months. What has been most surprising to me in the world of rockets? First, I didn't expect SpaceX to have this much trouble with Starship Version 2. Growing pains are normal for new rockets, but I expected the next big hurdles for SpaceX to clear with Starship to be catching the ship from orbit and orbital refueling, not completing a successful launch.

Starcloud can’t put a data centre in space at $8.2M in one Starship

Abstract Starcloud have claimed that a single 100-ton Starship launch could suffice to create a 40 MW space data centre (SDC) for $8.2 M. My analysis finds that this is infeasible in a single launch but requires a total of upto 22 launches. The SDC’s solar arrays require 4 launches determined by examining existing solar arrays on the ISS. Similarly, the ISS’s radiator benchmarks indicate that 13 launches would be needed for the SDC’s thermal management system. The server racks would require an

Anthropic summons the spirit of Flash games for the AI age

On Wednesday, Anthropic announced a new feature that expands its Artifacts document management system into the basis of a personal AI app gallery resembling something from the Flash game era of the early 2000s—though these apps run on modern web code rather than Adobe's defunct plugin. Using plain English dialogue, users can build and share interactive applications directly within Claude's chatbot interface using a new API capability that lets artifacts interact with Claude itself. Claude is an

People use AI for companionship much less than we’re led to believe

The overabundance of attention paid to how people are turning to AI chatbots for emotional support, sometimes even striking up relationships, often leads one to think such behavior is commonplace. A new report by Anthropic, which makes the popular AI chatbot Claude, reveals a different reality: In fact, people rarely seek out companionship from Claude and turn to the bot for emotional support and personal advice only 2.9% of the time. “Companionship and roleplay combined comprise less than 0.5

'Made in the USA' reference disappears from Trump phone listing

'Made in the USA' reference disappears from Trump phone listing "Speculation to the contrary is simply inaccurate," a spokesperson told the BBC. But the Trump Mobile organisation says the phone will still be made in America. A "Made in the USA" tagline featured in promotional material for the Trump T1 phone when it launched on 16 June, was no longer displayed on its site as of Wednesday, reporters found. Days after the Trump Organisation announced plans to launch a US-made smartphone, a refe
