I Thought AI Interior Design Was Mostly a Gimmick Until I Built One

For the longest time, I assumed AI interior design tools were just another "upload a photo and get a fancy render" demo. Then I tried building one. Turns out, generating the image is the easy part. The difficult part is making the result look like something a person could actually imagine doing to their room. One thing I noticed while testing is that people rarely ask for a complete redesign. Nobody uploads a picture of their bedroom expecting AI to magically create a million-doll...

How to redesign an app: Change nothing

I've never seen a project go so smoothly. Three developers, one fractional head of design, six weeks, virtually no production bugs. No heroics, no overtime — just a solid plan: constrain the problem, hand-craft the building blocks, and let an LLM safely do the manual labour. The pitch The app worked, it was simple, users even called it idiot-proof, but to be fair it didn't do all that much. None of us were really proud of it. The design wasn't consistent anywhere, each feature bu...

The Eligibility-Matching Problem Is Not Search — It’s Constraint Solving

Most startup funding platforms work like search engines. You type “AI grant” or “startup funding” and get a list of opportunities. But founders are usually asking a different question: “Can my company actually apply for this?” That is not a search problem. It is an eligibility-matching problem. A grant might require: a U.S.-registered company, fewer than 500 employees, majority founder ownership, a full-time technical lead, and an early-stage product. A search engine can fi...

I measured the RAG technique menu on 46,000 chunks. Four things mattered.

Search "advanced RAG techniques" and you'll get a list of twenty things: hybrid search, reranking, HyDE, query decomposition, contextual retrieval, RAPTOR, GraphRAG, parent-child chunking, multi-vector retrieval, semantic chunking. They're presented as a menu you work through, each one making your system a bit better. They don't compose like that. Techniques at the same pipeline stage mostly compete — they fix the same failure, so the second one you add finds nothing left to fix. And the on...

Building an Efficient Authentication Pipeline with ASP.NET Core, Playwright and Token Caching

Authentication is one of the most important parts of any application that integrates with external services. While many modern platforms expose OAuth APIs or SDKs for third-party developers, there are situations where an application needs to interact with an authentication flow that is primarily designed for browser users. Recently, while building a mobile application that integrates with an external football management platform, I needed to design an authentication architecture that was both...

Netlify's Hot AR Summer Challenge: I Wasn't Going to Enter. 33 Apps Later, I'm So Glad I Did

On Friday, July 31, I was at date night dinner with my wife in LA. We sat down at 8. The plan was simple: enjoy dinner, drive the hour home by 11, post my last app, close out the month. It was a five course tasting menu. At 9:15 we had finished exactly one course. I did the math at the table. Four courses to go, an hour of driving after that, and a deadline that did not care about either. So I picked up my phone in panic. Not my laptop, which was at home. My phone. I built the last one...

Deal-scoped PASETO: three things I got wrong about audience-bound tokens

The Model Context Protocol's authorization section says something blunt: a server must reject any token that was not issued for it. That has been normative since the 2025-06-18 revision rather than arriving with the current one, which is worth saying plainly because the interesting question was never whether the rule is new. I have been running a system where every credential is scoped to exactly one two-party transaction, so I want to write down what that actually took, including the third thin...

It Printed "Verifying." It Verified Nothing.

It printed "verifying sha256 digest." Then "success." The file it had just verified was 561 bytes of nulls, and its own filename said so. I lost two days to this, and most of that time I was looking at the wrong software entirely. What was actually happening I run AI agent frameworks in a hardened VM, because those frameworks execute code a language model writes, and their own documentation tells you not to run them anywhere near your real filesystem. The model lives inside...

GitHub Models Shut Down: What Beginners Should Learn About AI Vendor Lock-In

An AI feature can look permanent right up until the provider removes the sign from the building. GitHub Models reached that moment on July 30. GitHub had announced that the playground, model catalog, inference API, and bring-your-own-key endpoints would all be retired for existing customers, not just closed to new ones. I did not find a more substantial AI or developer-tool development in the previous 24 hours, so I widened the window to seven days. The shutdown happened three days ago. ...

GitHub finds your vulnerabilities. Something still has to manage them.

Turn on CodeQL, Dependabot, and Secret Scanning across a handful of repositories and you get exactly what the marketing promised: findings. Lots of them. Each one sitting in its own repository's Security tab, behind its own set of tabs and filters, with no shared notion of who owns this , when is it due , or are we getting better or worse . That's the gap. GitHub is genuinely world-class at the detection half of application security. The operational half - triage, deadlines, ownership,...

Dollars and rupees without Stripe: what building Skill Exchange's checkout taught me (PayPal + UPI)

"Just add Stripe" is the default advice for a solo dev who needs to charge money. It works right up until you're an Indian merchant trying to sell to a buyer in San Francisco and a buyer in Bangalore in the same afternoon — at which point you discover that a single provider can't actually do both, and the fix rearranges more of your code than you'd expect. I hit this building Skill Exchange (a marketplace for reusable AI skills — link at the end). The marketplace itself isn't the point here...

https://b4uwork.vercel.app/ I created a free public UK trust score that searches for thousands of public sources and documentation (without AI) about a business and creates a clear 0-100 score. This is designed to be a mobile app, so I don't want marketing websites in front of the application. It should be open, search, and result. The idea is minimal wait times, minimal clicks, minimal screens, simple navigation, and easy to understand information, free and unlimited. Nearly all feedback...

The biggest problem with vibe coding isn't security

Some context on who's writing this... I have built software for 8 years and now run a small AI consultancy. A growing share of our work lately isn't building new products at all, it's rescuing vibe coded ones that already have paying customers. So I get why security dominates the conversation. The leaked keys and open endpoints are real but security is a known category of problem. You can buy an audit for it and the thing I keep running into on these rescue jobs doesn't have an audit and it bo...

Chat linked to Apple Health?

I got a notification that Chat can now link to Apple Health. On the one hand, that seems so incredibly helpful in a lot of ways. On the other….well…..this could go terribly wrong in so many terrible ways. If I’m already giving the information to Apple and my health insurance company, that I trust exactly as much as I trust Facebook, does it even matter if I give it to Chat???

Today, between 4:00 p.m. and 5:00 p.m. Eastern Time, I had to restart at least ten voice calls. The app frequently displayed “unstable connection,” and the conversation would suddenly end.
