Emergent Design & Gall's Law: When Complex Coding Problems Dissolve Instead of Being Solved

I recently read an article by the main maintainer of InversifyJS describing the journey of rebuilding its dependency resolution algorithm. What caught my attention wasn't the performance improvements or the technical details. It was something much more familiar. As I was reading, I realized they were experiencing the exact same phenomenon I had experienced years ago while creating InversifyJS. It...

How to store AI-generated images per user in object storage and delete the old ones

Use one key prefix per user, delete from the application every key you can name, and leave lifecycle rules to sweep the old temporary images nobody will ever ask for again. That's the whole design, and I've watched teams get it wrong in the same two ways for years: they either try to make the storage layer clever enough to know what a user is, or they hand the entire deletion problem to a lifecyc...

How to Catch AI Hallucinations: A Copy-Paste Hallucination Checker Prompt (Tested)

You ask an AI a question. It answers in fluent, confident prose — complete with a study, a percentage, and a name. Some of it is wrong, and nothing about the wording tells you which part. That's the whole problem with hallucinations: the errors wear the same suit as the facts. The fix is not "trust it less" in some vague way. The fix is a repeatable audit step between AI wrote it and I used it. B...

Why Your AI Agents Need Finite State Machines: Building Deterministic Workflows in a Vibe-Coding World

Originally published on tamiz.pro. The rise of "vibe coding" has democratized software development, allowing developers to build complex applications using natural language prompts. However, this same flexibility introduces a fundamental challenge for enterprise-grade AI agents: non-determinism. When you ask an LLM to "handle this customer support ticket," the model might draft an email, query a ...

Pokémon Emerald [tif]

Similar to the Pokemon Yellow recently, I had a GBA Emerald Green sent in for repair. Just 24 hours ago, this was going to be a post on how I had failed to repair it, but in a last minute ditch, I managed to save it. Loading up the game resulted in nothing, and opening the shell explained why. There was a lot of corrosion around the PCB, but more importantly, two of the legs on the ROM had complet...

CRM for Startups: How to Build a Scalable Customer Workflow

Startups often manage their first customers through spreadsheets, email threads, messaging apps, and personal notes. That approach may work when the company has only a few leads, but it becomes difficult to maintain as the team and sales pipeline grow. A customer relationship management system, or CRM, gives a startup one place to organize contacts, record conversations, monitor opportunities, an...

We're getting close to the last part of iteration one — the skeletal build of the site. Good! I'm getting eager to get on with the design work now. For some reason, doing this series (along with being busy in general) has stifled my ability to think creatively about my site. I guess I need to get all the non-technical stuff published to let my brain fully switch. Brains are weird, man. Anyway, we...

Microsoft Copilot for Word Can Copy Hidden Prompts Into New Documents

Hidden instructions in a Word document can make Microsoft 365 Copilot rewrite figures in a report, then copy the same instructions into the finished file. Håkon Måløy disclosed the technique on July 28, 144 days after reporting it to Microsoft. In his proof of concept, the internally generated file triggered the same behavior when it was used in a second Copilot drafting session. Måløy's
