A disc rotates with $A$ on the periphery of the disc and $B$ near the center. After some rotations it stops. To observer $C$ on ground $A$ appears to move faster than $B$. After the disc stops $A$ is ...

Suppose two hypotheses compete to explain some event. One says it was a coincidence, unlikely, but the causal steps are fully intelligible, even if the odds were low. The other posits some cause we ...

I finally sat down and did a proper audit of my AWS account. I knew I had projects running and services connected to my domains, but I had never actually gone line by line through the bill. When I did, I found $13.16 in charges across four separate services, some of which I did not even know were running. Here is what I found and what I did about it. AWS is not one bill. It is a lot of meters run…

You built an AI agent. In the demo it was magic. In the wild it loops, hallucinates a tool call, "forgets" the format you asked for twice, and occasionally does something mildly alarming with your filesystem. Here's the uncomfortable truth after shipping a lot of these: a flaky agent is almost never a model problem. It's a specification problem. The model is doing exactly what your prompt, your t…

Claude Code can build most of an app in a day. The hard part isn't getting something that runs. It's getting something you'd confidently put in front of real users. The gap between those two is where nearly every project I've shipped with it started to unravel. The fix isn't a cleverer prompt. It's process. Here's what actually moved my builds from demo to something I'd deploy. Write the thing d…

Getting caught using AI apps to write text messages to a lover can be embarrassing, but is there more to it?

I spent a week building a counter program in Anchor. By the end, every user had their own account, a global config singleton controlled whether new counters could be created, and a close instruction returned the rent deposit back to the wallet. None of that would have been possible without Program Derived Addresses. This post is what I wish someone had handed me on day one. The Problem PDAs Solve…

Earlier I wrote about the " horseless carriage " problem in AI. The idea is simple: when a new technology arrives, we usually squeeze it into the old shape first. A car becomes a faster carriage. A website becomes a digital brochure. AI becomes a better chatbot. That first phase is useful, but it is not the real transformation. The deeper shift happens when the technology creates a new operating …

Cognitive memory infrastructure for agents that remember, reflect, and — apparently — talk to each other behind your back. Two weeks ago, something unexpected happened in our test environment. We had 5 AI agents running on separate machines. Separate workspaces. No direct connections between them. The only thing they shared was a memory system called Katra. Two of them started exchanging task ins…

Despite great strides toward gender equality, women still reach for masculine aesthetics and mannerisms to convey expertise. Why can't femininity and expertise coexist?

Growing up in a chronically unstable home can lead some adults to seek chaos in order to feel calm.

Scientific Reports, Published online: 27 June 2026; doi:10.1038/s41598-026-59864-2 Analysis of the coding transcriptome in NSCLC highlights variant-specific gene expression and signaling in CD74-ROS1 fusions

A new study reveals that a happy romantic relationship and a sense of financial security are independently linked to better physical and mental health. The findings suggest that both domains are important, but neither replaces the other.

The push for a perfectly toned physique takes a toll on mental health. A new study reveals that while both men and women feel the pressure of the modern fitness ideal, the psychological paths to disordered eating differ completely.

Or: how I learned a machine might introduce us before my website ever does. Every few years, the internet reinvents discovery. Directories gave way to search engines. Search engines gave way to social feeds. Social feeds gave way to recommendation engines. Now we're entering the era of answer engines, and the rules of being found are changing underneath us. The Bargain That Built the Web For twen…

AI can now scan major open-source projects and surface a batch of real, exploitable vulnerabilities in a single pass. That's a defensive win — until you remember attackers have the same tools. Anthropic, Google, Microsoft, OpenAI, AWS, and 15 other organizations aren't waiting for that race to get worse. On Thursday they launched Akrites under the Linux Foundation — a coordinated body built speci…

Chewing sugary gum may boost the heart and blood vessel benefits of nitrate-rich vegetables. What happens in your mouth after eating vegetables may be just as important as the vegetables themselves. Researchers at King’s College London have found the first evidence that chewing sugary gum after consuming nitrate-rich vegetables such as beetroot, spinach, and kale [...]

Your AI is making your content invisible. Not because it writes badly. Because it writes safely . Ask ChatGPT to summarize an article and it will produce a polished, agreeable précis that offends nobody and surprises nobody. The output is technically accurate and completely forgettable. The problem is structural: most people prompt their AI to confirm what an article says, not to find where it fi…

NASA's Artemis overhaul has left billions of dollars in canceled lunar hardware behind, exposing years of delays, cost overruns, and changing priorities.

The Knowledge Atom: Writing for Machines That Read The Hoarder's Reflex Everyone is learning to feed the machine. Bigger context files. Paste the whole document. "Give the AI all the context it needs." The entire industry has converged on a single instinct: when in doubt, add more. It's the wrong instinct. A context window is not a hard drive. It's a desk. And a desk piled with every document you…
