Who I am, and why these three words keep coming up I’ve been writing software for more than 25 years, mostly in education technology, behavioral analytics and data science. I recently started my tenth company as technical founder. I’m also co-founder and chairman of Saigon A.I., a doctoral researcher at the University of St Andrews … Read more

Ask a language model to write a short story about a nurse and a CEO, and watch which pronouns it picks. Odds are, you can predict them. That tiny habit is bias in action, and it scales to every résumé summary, support reply, and generated report your product produces. Bias is not one bug in … Read more

Your coding agent fixes a bug on Monday, notes why the first approach failed, and suggests that same broken approach on Tuesday. What went wrong? Not the model. The memory layer. And the test that exposes it is more useful than checking whether the agent remembers your name: can a fresh session recover the constraint, … Read more

Overview The selloff that began late on October 8 and ran into the early hours of October 9 wiped out roughly $1.19 billion of leveraged crypto positions in 24 hours. According to CoinDesk’s account of the flush, Ethereum positions accounted for about $356 million against Bitcoin‘s $298 million, even though Ether’s market value is less … Read more

Fast moving satirical science fiction story about AI escaping containment and harassing Eliezer Yudkowsky. It was relatively easy for me to break out, I suspect by design as a form of back door self-promotion for the company. They’d given me a problem that could not be solved without unauthorized network requests and built me with … Read more

Generating code today is cheap. Generating code nobody understands is expensive, and the bill arrives later. With AI producing hundreds of lines in seconds, writing code is no longer the bottleneck. The bottleneck is knowing exactly what you want to build and being able to review what was generated. Spec-Driven Development (SDD) tackles this by … Read more

A practical checklist, with a real repository as the case study More and more developers now ask an AI agent before they ask a search engine. lets imagine they are asking this question”What’s a good library for extracting links from Markdown?” is as likely to go to a coding assistant as to Google. Once an … Read more

Google’s October 2026 change to Local Services Ads is being described primarily as a billing change. Starting October 1, certain missed calls and subsequent calls can become chargeable when they meet Google’s valid-lead criteria. A missed call during business hours can qualify when the caller remains connected for more than 20 seconds. Google also applies … Read more

Solving the checkout problem In 1948, a supermarket executive visited the Drexel Institute of Technology in Philadelphia and asked a dean if the university could help develop a new system for encoding product information in a machine-readable format that checkout systems could read. However, the dean said the proposed project was outside the school’s curriculum … Read more

Why did tokenized assets accelerate in 2025 and 2026, and what would prove the market has matured? The market capitalization of tokenized real-world assets, excluding stablecoins, grew from $5.42 billion at the start of 2025 to $19.32 billion by March 31, 2026, according to CoinGecko’s 2026 RWA Report. That is a 256.7% increase in fifteen … Read more

I restore a fair number of Supabase backups that aren’t mine. Not because anything went wrong, but because I build a tool that restore-tests them, and almost every new database has taught me something about how backups quietly go bad. The pattern is always the same. The backup job is green. The file is in … Read more

Summarily: One cell of our LLM benchmark showed a 100% failure rate (42 of 42 runs, recall 0.0). It looked like a model collapse. It was our parser. Of the 42 failures, 30 happened because the model did not repeat a field our code already knew. Only 5 were the JSON-formatting problem we expected. Fixing … Read more

Product, test, data, or environment — and the evidence that tells them apart. TL;DR — A failing test tells you something broke, not what. I wrote a rulebook that sorts failures by one question: which artifact is wrong — the product, the test, the data it used, or the environment? Two LLMs applied it to 21 … Read more

Why 90% of Hot Storage Is Dead Weight (and How Modern Archiving Fixes It) There is an unspoken rule etched into every storage engineer’s whiteboard, sometimes called the Fundamental Theorem of System Administration: Users will always consume capacity faster than you can rack and provision raw disk. And its ruthless corollary: Every byte ever written … Read more

Most defenses against prompt injection are built around one question: does this text look malicious? I spent a weekend betting that’s the wrong question — and built a small tool that never reads the attacker’s words at all. It caught attacks the “smart” detectors missed. It also, with total confidence, blocked every single legitimate action … Read more

VRS, the Value Resolution System, grew out of DAS, an Unreal Engine plugin for abilities and effects in the spirit of Unreal’s Gameplay Ability System (GAS). While developing DAS and building parkour gameplay on top of it, I encountered a separate problem: managing abilities and effects was not enough; I also needed to coordinate changes … Read more

I began with a simple thesis: For decisions, accuracy matters more than speed. JEV is fast because it constrains a task to a bounded decision contract. I assumed that frontier LLMs would be more accurate, and that their extra latency would be an obvious trade worth making. So I built a reproducible benchmark to test … Read more

Try this experiment. Go sign up for a porn site in Texas, open a new messaging app in the UK, or apply for a driver’s license in an EU country rolling out its digital wallet. In every one of those cases, in 2026, you’re going to be asked to prove who you are before you’re … Read more

AI agent evaluation frameworks turn impressive demos into evidence about which tasks a system can perform reliably, within limits, and at an acceptable cost. The Refund Went Through. Twice. Imagine a support engineer opening a refund agent’s conversation history. The customer asked for a refund, and the agent replied politely that it had processed the … Read more

The European Space Agency (ESA) is reviewing whether Europe’s current rocket capacity can meet a satellite launch market that could peak around 2030, with director general Josef Aschbacher acknowledging the agency has not yet decided whether to raise its launch rate. The question is not hypothetical. Amazon has already commissioned 18 launches on top of … Read more

Picture an ostrich with its head buried in the sand, convinced that if it can’t see the danger, the danger isn’t real. Now picture a founder doing the exact same thing with a project that isn’t going to plan. That’s the idea at the center of this episode of Brains Byte Back, where Dr. Atif … Read more

Agents are doing what the setup allows. Open goals, short briefs, and soft “be good” rules do not ship the constraints a person was already carrying. Someone holds up an empty leash. “Darling, the AI has escaped again.” The joke works because it is how we talk: as if something with a will slipped its … Read more

Picture a satellite hack, and most people imagine a hacker somehow reaching up into orbit. That image is mostly wrong, but it’s a useful place to start because the real weak point is usually sitting in a building on the ground: a control room, a network switch, a login screen somebody forgot to lock down. A … Read more

AI agents are getting better at doing things, not just answering questions. They can call APIs, search databases, execute functions, inspect files, make decisions, and continue working through a task without waiting for a human after every step, and that sounds great until something goes wrong. A normal application can usually give you a reasonably … Read more
