Advertising still speaks the language of manufacturing. Campaigns are launched. Creative is produced. Audiences are bought. Results are reviewed after the campaign has run its course. That vocabulary assumes an ad is a finished object. Generative AI breaks that assumption. An ad no longer has to be a fixed combination of image, copy, audience, placement, … Read more

I built a natural-language product search engine over a marketplace catalogue in twelve languages. The interesting failures were not in the model’s language understanding — that part mostly worked. They were in the seams: a price filter that had never once filtered, an LLM confidently inventing valid-looking category IDs, a substring match that turned “newborn” … Read more

Images are essential to modern websites. They make product pages more persuasive, break up long articles, explain complicated ideas, and give brands a recognizable visual identity. The problem is that images are also capable of adding a substantial amount of data to a page. When they are prepared or delivered incorrectly, visitors can end up … Read more

For the past couple of weeks I’ve been playing through Hacker Holidays 2026 – “The Byte Lotus,” TryHackMe’s resort-themed CTF: 14 rooms unlocking one a day (Jul 27 – Aug 9, 16:00 UTC), all wrapped around a luxury-hotel story starring VERA, the resort’s a little-too-helpful AI concierge. What I liked about this event is how much ground … Read more

The science, the systems, and the very expensive question of who gets to keep living Every human being who has ever lived has been party to a contract none of us signed. The terms are simple.

I ended the last article (Linked: Part 2) on a single root cause, structured, quantitative data forced through a pipe built for unstructured language, producing the linearization defect during extraction and the tokenization disconnect during embedding. The natural conclusion is that you need a better extractor. That conclusion is half right, and the missing half … Read more

You spent three hours debugging a broken ETL script, your data is sitting in five different places in five different formats, and the stakeholder meeting is tomorrow morning. If you’ve ever stared at a pile of raw CSVs, API responses, and database dumps wondering how to wire it all into something that actually works reliably, … Read more

I had a page from Lost Garden, my AI anime series, that read fine on paper. One line said the heroine was torn between trusting the stranger and running. Any script reader would get that instantly. A generation model turned it into a woman standing still, doing nothing, wearing an expression that could mean anything … Read more

Denial of service is the least fashionable category in security because nothing is stolen and nothing is forged and the report at the end of it reads like a capacity planning memo rather than a crime scene. On most infrastructure that reputation is deserved, since a process that exhausts its heap will trip a pager … Read more

AI code review is a dedicated verification discipline — not a feature of your generation tool. Understanding what it analyzes, where it fits in your SDLC, and how to evaluate tools on rigorous benchmarks is what separates teams that ship confidently from teams that ship fast and fix later.

Adversary is a memory matching game with one change to the usual formula: hidden among the matching pairs is a Danger card that can mess up your round.

Roughly $972 million was lost across 207 incidents in the first half of 2026, less than half the total of the same period a year earlier, while the incident count more than doubled from 83 and set a record. Attacks became more frequent and less profitable at the same time. That is a change in … Read more

I have a contrarian bet that drives my research and my writing. Token economics, cost per inference, and carbon footprint will determine which AI programs survive past 2027. Boring infrastructure math, not model capability, will sort the winners from the failures. If that bet is right, we are teaching the next generation of builders the … Read more

Picture the moment every agent builder eventually hits.  You’ve got a script working. It reads a task queue, calls an LLM, executes a few tool calls, writes some output, and loops. In a terminal window, on your laptop, it looks like magic. So you do the obvious thing: you let it keep running. You close … Read more

Why Enterprises Need an Agent Framework as Their AI Operating System Large Language Models, or LLMs, have reshaped how people use and interact with software. a few years ago conversational AI was more of a niche research topic.

Companies keep building the website. More pages, better copy, a rebuilt pricing page, a resource library. Buyers stopped reading it. Forrester surveyed close to 18,000 business buyers in 2025. Ninety-four percent used AI somewhere in the buying process, up five points in a year. Twice as many named generative AI or conversational search their most … Read more

Every automated system that still has a human with override permissions is not an automated system. It is a hybrid, and the human half never gets profiled. I spent years shipping trading rules I described as systematic. Entry conditions in code, stop distance in code, position size in code. And then, most days, I would … Read more

Every AI cost-attribution tool I looked at works the same way. You point base_url at their gateway, they see every request before it happens, and in exchange you get real-time blocking if a call is about to blow your budget. That’s a fair trade for a lot of teams. It was not the trade I … Read more

I’ve been running an AI agent on a Raspberry Pi 5 for the past three months. It writes code, browses the web, manages my email, and even deployed a production SaaS to a DigitalOcean droplet last week. The whole setup costs zero dollars in API fees because every inference runs locally on the Pi itself. … Read more

Software is completely changing. The cost of building something is a race to zero, but the cost of getting an audience and distribution isn’t getting easier or cheaper.
