Pinocchio is weirder than you remembered
The original 1881 serial ended in chapter fifteen with the puppet hanging dead from an oak tree. Italian children wrote in begging the author to continue. He resumed reluctantly. What followed — donkey-skin drums, dead-girl fairies, a satire of every other moralising children's book in Italy — became one of the most…

Reverse-engineering the 1998 Ultima Online demo server
After 10 years of on-and-off work, I’m releasing a full reverse-engineering of the 1998 Ultima Online demo server: https://github.com/draxinar/ouo . About 5,000 functions disassembled from MSVC x86 and translated into portable C99, with each function compared instruction-by-instruction against the binary.

Multi-stroke text effect in CSS
I used to see that retro multi-stroke text effect quite often and tried to replicate it using the CSS text-stroke property, but the results never quite matched. Because text-stroke accepts a single value, stacking elements was the only workaround I could think of, though it didn't seem to work.

I'm scared about biological computing
I’ve been in the AI space since ChatGPT first dropped. I’ve toyed around with a lot of Language Models, built random side projects, built a couple from scratch and I’ve spent hours looking at the math behind it all.

Three Inverse Laws of AI
Since the launch of ChatGPT in November 2022, generative artificial intelligence (AI) chatbot services have become increasingly sophisticated and popular. These systems are now embedded in search engines, software development tools as well as office software. For many people, they have quickly become part of everyday…

AI didn't delete your database, you did
Last week, a tweet went viral showing a guy claiming that a Cursor/Claude agent deleted his company's production database. We watched from the sidelines as he tried to get a confession from the agent:

A polynomial autoencoder beats PCA on transformer embeddings
A closed-form autoencoder: PCA encoder + quadratic Ridge decoder. On FiQA it gives 4× compression of mxbai-embed-large-v1 at -0.88 p.p. NDCG@10, +1.34 p.p. over PCA. No SGD, no neural networks.

When everyone has AI and the company still learns nothing
Are people using AI, or is the organization learning from it? What changed because we spent those tokens? And who moves discoveries from individuals to teams to organizational capabilities?

Google Chrome silently installs a 4 GB AI model on your device without consent
Google Chrome is downloading a 4 GB Gemini Nano model onto users' machines without consent, with no opt-in, no opt-out short of enterprise tooling, and an automatic re-download every time the user deletes it. The pattern is identical to the Anthropic Claude Desktop case I wrote about last month, but the scale is…

Hand Drawn QR Codes (2025)
I really like QR codes. Recently I purchased a new sticky-note-like pad from a new local stationery store in Minneapolis. The sheets have a 10x10 grid and 2x10 grid. I knew what I wanted to...

CVE-2026-31431: Copy Fail vs. rootless containers
In the previous post about SELinux MCS and GitLab runners, I briefly mentioned CVE-2026-31431 (“Copy Fail”) as a motivating example for per-job VM isolation. After that post went out I spent the weekend setting up a lab to actually run the exploit, trace it at the syscall level, and verify that the rootless Podman…

Y Combinator's Stake in OpenAI (0.6%?)
The fact that Paul Graham personally has billions of dollars at stake with OpenAI doesn’t mean that his public opinion on Sam Altman’s trustworthiness and leadership is invalid. But it certainly seems like the sort of thing that ought to be disclosed when quoting Graham as an Altman character reference.

Bun is excellent software. Anthropic owns it now, Bun sits under Claude Code, and Claude Code getting worse makes me worried Bun could follow the same enshittification path.
