AI Hallucinations Are Still Not Solved

With every major model release comes the same reassuring note: hallucinations are down, reliability is up, the fabrication problem is largely behind us. And every release, within days, someone posts a screenshot of the new model inventing a citation, a quote, a case, a statistic or a person with total, serene confidence. The rate improves. The category does not disappear. It is worth understanding...

Why Every AI Startup Looks the Same

Spend an afternoon browsing new AI startups and a strange déjà vu sets in. The landing pages rhyme. There is a dark hero section, a gradient somewhere between indigo and violet, a little sparkle or star icon denoting Intelligence, a headline promising to let you “chat with” your documents or data or customers, and a demo video with the same upbeat, slightly anonymous soundtrack. You could swap the...

Why AI Benchmarks Mean Less Than You Think

Every model launch comes with a chart. Bars, usually, or a spider diagram, showing the new model edging past its rivals on a row of benchmarks with acronyms most people cannot expand. The bar is taller. The press writes it up as a leap. And within a week, users report that the new state-of-the-art model is, for their actual work, about the same as the last one or occasionally worse. The benchmark ...

The Problem With AI “Memory”

“Memory” is the feature everyone asked for and few thought through. The pitch is lovely: the assistant remembers your preferences, your projects, your writing style, the fact that you are vegetarian and allergic to long emails, so you never have to repeat yourself. In practice, it is one of the most consequential privacy decisions in consumer AI, dressed up as a convenience toggle, and most people...

When AI Refuses Perfectly Normal Requests

Ask a modern chatbot to help with something completely ordinary and there is a growing chance it will decline. Not because the request was dangerous, but because it brushed against a keyword, a topic, or a category that the vendor's safety systems treat as radioactive. A recipe that mentions alcohol. A history question about a violent event. A medical query you were entitled to ask. A creative sce...

Why AI Product Launches Feel Identical

Watch enough AI launches and they begin to blur into a single, endlessly repeating event. There is the understated title slide. The claim that we are at an inflection point. The chart showing the new model clearing a row of benchmarks. The live demo that works flawlessly. The superlatives — most capable, most advanced, our best model yet. And the closing note that all of this will roll out “over t...

OurBook: el MCP donde tu agente recuerda vuestra historia (no tus datos)

La mayoría de los "agentes con memoria" recuerdan datos: un string, un hecho, una preferencia. Pero cuando hablas semanas con un agente, lo que quieres no es una base de datos con tus notas. Quieres que recuerde vuestra historia: el día que conociste a su perro, la vez que os reísteis de una idea absurda, lo que prometisteis hacer juntos. Y, sobre todo, quieres que no confunda lo real con lo soña...

We Will Get You Through It!

There is a comedy sketch from Bob & Tom that starts with a hilariously impossible promise: overnight delivery by train, from New York to Los Angeles. At one point, someone asks if they can really get a 2,000-pound package across the country overnight by rail. The answer is delivered with absolute confidence: “Norfolk and Waypal, overnight. Absolutely. Positively.” The name is doing s...

JWT Authentication in Express That You Can Actually Revoke

Access tokens, refresh token rotation, and theft detection: the parts most Node.js tutorials leave out. A friend messaged me about his side project a few months ago: "Someone else is logged into my account. I changed my password. They're still in." He had followed the tutorials to the letter. Sign a JWT on login, send it to the frontend, keep it in localStorage, attach it to every request....

You would never install random software from a forum. Then you walk into your living room that has 14 always-on microphones, 6 cameras, 3 devices that map your floor plan, and a router you have never audited, all running firmware you have never ...

From Arduino To Automotive: How I Escaped The IDE And Owned The Bus

Arduino taught me how to build. Bare metal taught me how the build actually works. I have a lot of respect for Arduino. I mean that sincerely. It is a legitimate engineering platform, not a toy. It put a C compiler, a bootloader, and a sane hardware abstraction layer into the hands of millions of people and said go make something. Museums run on Arduino. Satellites have run on Arduino. My first t...
