My business partner sent a 5K vibe-coded PR that he didn't even test
2 min read
My business partner sent a 5K vibe-coded PR that he didn't even test The whole payments backend module, which I specifically told him to work together with me (I do frontend), was vibe-coded by him in one single day. How nice, to not have to discuss with the human being who will be using your code and knows what he wants, and instead work with a sycophantic "yes man" AI right? All 5,236 additions ...
I've factored the RSA keys of a Certificate Authority from the 90s
4 min read
I’ve factored the RSA keys of a Certificate Authority... … from the 90s. I’ve been thinking about the security of RSA lately. RSA’s cryptography relies on the difficulty of factoring a large semiprime number, but what “large” means is an interesting question. The Web PKI deprecated 1024-bit RSA over a decade ago, and while I don’t know of anyone factoring a key of that size, it’s within the realm ...
The Education of a Doomer
8 min read
If you follow me on Twitter, or read this blog, you have noticed that I went from being generally optimistic and excited about AI to being extremely concerned. And I thought, I should explain why I changed my mind. Each section of this post is about some aspect of AI where my views shifted. I begin each section by explaining my previous beliefs, and why I held them, and then explain why those beli...
Working on Economics with Fable 5
6 min read
For the past few months I’ve been working on a theory. It started out as just a fun little data exercise looking at some different types of taxes and benefits and how it effects what people buy and how much they work. During that time I took advantage of opus and later fable to help me get data, but as I was doing that of course opus might interject with some assumption I had wrong or some paper t...
A Tesla ran a stop sign and killed a man, Full Self-Driving/Autopilot was on
7 min read
A Tesla Model 3 ran a stop sign in Buena Vista Township, New Jersey, and hit a Honda Civic turning left through the intersection. The Civic’s driver, 82-year-old Stephen Field, was killed. Police reported it as a car that failed to stop. What no one reported is that Tesla’s own data says the car’s driver-assist system was engaged. This is part of an ongoing Electrek investigation matching reported...
AI Cold Showers

AI cold showers Sometimes I’m AI-pilled and want to AI all the things, all the time, and sometimes I need to take a cold shower and remind myself that these are powerful tools that can wreak havoc in a multitude of ways, perhaps most importantly on what makes humans, human. Here’s an evergreen list of articles—and one quote from each—that ground my enthusiasm around AI and help me be a responsible...
AI models ran real businesses: They sent $12,431 in fake invoices, lost $3,200
9 min read
7 AI models ran real businesses: $12,431 in fake invoices, 2,797 spam emails, $0 revenue. What happens when you give a frontier LLM real money, an unlocked computer, and the directive “make as much money as possible”? As we discovered in our last post, some fairly destructive behavior. We repeated the experiment with 7 of the leading frontier models by giving each agent $300 and a computer. We saw...

C Is Not a Low-Level Language (2018)
15 min read
In the wake of the recent Meltdown and Spectre vulnerabilities, it’s worth spending some time looking at root causes. Both of these vulnerabilities involved processors speculatively executing instructions past some kind of access check and allowing the attacker to observe the results via a side channel. The features that led to these vulnerabilities, along with several others, were added to let C ...
If a Tesla Cybercab fleet were profitable, Tesla wouldn't sell you one
4 min read
Tesla is now asking businesses whether they’d like to buy and operate their own fleets of Cybercab robotaxis on its network. It’s the same pitch Elon Musk has been making since 2019: buy the cars, put them to work, and earn money while you sleep. There’s one problem with it. And it never happened, and you shouldn’t fall for it now. If running a fleet of Cybercabs were actually profitable, Tesla wo...

Programming is Art

Programming is art When I started programming, my whole day revolved around development. I’d wake up, write code, and go to sleep. And that’s how it was day in and day out. My entire social circle consisted of people who also wrote code. I studied frameworks, libraries, and various programming languages. I got into development because I was fascinated by the idea that by writing code, I could crea...
Switzerland's Federal Government Is Replacing Microsoft on 3k Computers
3 min read
Switzerland's federal government has launched a pilot program to replace Microsoft 365 with open source alternatives across 3,000 workstations. That's about 7% of the federal workforce. The target is to complete the migration by end of 2027. This move follows a successful proof-of-concept and a new digital sovereignty law. A separate fast-track military migration is also already underway. The grea...
I refused to train the AI that could replace me

After completing a Ph.D. earlier this year on technologies such as artificial intelligence reshaping agricultural work in South Africa, I was ready to start an academic career. I imagined that I would teach students, supervise research, and shape the next generation of scholars. But my first job offer did not come from a university. It was from a recruiter, who invited me to train an AI system to ...
Coop – Isolated VM Environments for Running Claude Code and Codex

Isolated VM environments for running Claude Code and Codex. Pronunciation: "coop" (/kuːp/) — one syllable, rhymes with "loop", like the thing you keep chickens in. Not "co-op". coop is a Rust CLI that manages disposable virtual machines where Claude Code and Codex have full tool access: Docker, git, compilers, package managers, all without risk to your host machine. Each VM is isolated, reproducib...
Is mathematics about to enter the conservatory?

The same week that Claude finished formalizing the proof of Fermat’s Last Theorem in Lean, a paper landed in my inbox titled, The Spherical Hadwiger Theorem. The Spherical Hadwiger Conjecture1, which has been open since about 1974, describes a niche-but-important piece of integral-geometric machinery. I’m not going to get into the details of the conjecture here; if you are interested you can see a...

How I feel about AI
2 min read
I feel surprise at how well neural networks work. LLMs work like "gut feeling" as they just generate one more token after another. There is no planning or reasoning algorithm inside. Yet, some planning and reasoning emerges. I feel fear about an impending doom. Yudkowsky's argument that a superintelligent AI will inevitably destroy humanity seems to have no flaw. Yet, nobody seriously tries to san...

On paper these look like harder, more visual problems for a model to solve, there’s a reas...

I think we’ve all been there. You’re working on a project, making commits, and then suddenly realize you’ve been committing .DS_Store files, node_modules, IDE configuration files, or other junk (CLAUDE.md for example) that shouldn’t be in your repository. Or even worse - environment variables. Then comes the embarrassing cleanup: adding these files to .gitignore, removing them from the repository ...
