I was burning context feeding HTML to LLMs, so I built a Markdown converter for agents

If you build AI agents, scrapers, or RAG pipelines, you have run into this: feeding raw HTML to a model is mostly waste. The <div> , the class="..." , the nav, the cookie banner. None of it is the content you wanted, and all of it costs tokens. I knew this was inefficient. I did not appreciate how inefficient until I measured it. Here is a single page of GitHub's documentation, run through an audit: HTML Markdown Savings ───────────────────────────...

A practical CSS variable setup for light/dark mode without theme flash

Dark mode is easy to start. It is harder to ship cleanly. Most implementations need to handle: light mode dark mode system preference stored user preference a toggle button no flash of the wrong theme on page load The flash is the annoying part. You save the user's choice in localStorage , but your app JavaScript usually runs after the browser has already started parsing HTML and CSS. So the page may briefly render in the wrong theme before your JavaScript applie...

AI made coding boring and nobody wants to admit it out loud

There was something fulfilling that died within me when I no longer had to debug my code. I can't tell you the specific date that this feeling began to spread. But there's a growing chorus of experienced developers saying the quiet part out loud: coding isn't fun anymore, and AI might be the reason. The Thread That Hit a Nerve A viral thread in a popular senior developer community recently went boom. The premise was simple: “coding doesn't seem fun anymore.” It wasn't burnout ...

How I Built a Premium Developer Tools Website Using Only a Local LLM (Gemma 4:12B + Ollama + VS Code)

Over the past few weeks, I’ve been experimenting with local language models. Like a lot of developers, I’ve used cloud AI assistants quite a bit, but I kept asking myself one simple question: Can a local LLM actually help me build a real, production-ready project? So I decided to find out for myself. I challenged myself to build an entire developer tools website using only a local AI model running on my own machine. No cloud assistant. No external API. Just my laptop, VS Code, Ollam...

O-AI Development Update

I wanted to share a quick update on how O-AI is progressing. Over the past few weeks, I've been rebuilding and improving almost every part of O-AI. The goal has always been to create something that's genuinely useful—not just another AI chatbot. Here are some of the biggest updates so far: • O-AI Agent Extension – O-AI is evolving beyond simple conversations and can now work more like an AI agent, capable of handling more advanced and multi-step tasks. • O-Code – A dedicated coding e...

I Built a 131-Test Eval Harness Before Writing New Features. Here's the Silent Failure It Caught.

Originally published on AIdeazz — cross-posted here with canonical link. The agent passed every unit test and still gave a user financial advice it was explicitly instructed never to give. No exception thrown, no log line in red, no failed assertion. The function returned a clean 200 and a well-formed string. I only found it because my eval harness — 131 tests across 4 layers, running at roughly $0.03 per full pass — flagged a semantic regression that no assertEqual could ever have caugh...

9 GitHub Projects Worth Building If You're Serious About Physical AI and Robotics

If you're trying to break into physical AI or robotics, you've probably already noticed that the field has a specific problem: everyone's resume looks the same. ROS 2. Python. Computer vision. Familiar with deep learning. None of that tells anyone anything useful. What actually matters in this field is whether you can take a pile of hardware, write the software to make it work, and ship something that runs reliably in the real world. That's a very different skill from knowing the right key...

AI Is Too Good at Coding - So I Built Something to Keep the Why (and Make It Scale)

Over the past few months I've been building with Cursor, Claude Code, and Codex - same tools a lot of builders are running right now. The pace is genuinely wild. I've shipped MVPs for friends where we went from a rough PRD to a working demo in a single day: auth wired up, database in place, deployed, link sent before midnight. Some of it fully vibe-coded. Some of it structured. All of it fast. You're seeing this everywhere now. Builders spinning up entire products over a weekend, sometimes ov...

The Feynman Technique Prompt: How to Make AI Explain Anything in 4 Layers of Depth

You asked ChatGPT to explain self-attention. It gave you a paragraph that sounded right. You nodded. Two hours later, you couldn't explain it back to yourself. That's not a knowledge gap. That's a prompting gap. You asked the model to explain, but you never told it how deep to go — or at which level you actually needed the explanation. So it defaulted to a single-register answer that optimized for sounding helpful rather than for making you understand. The Feynman Technique fixes thi...

Lessons from building a QR-paired browser handoff tool

I have been working on a small browser handoff tool. The use case is intentionally narrow: open a page on one device, scan a QR code with another device, then move live text or one selected file between the two browsers without creating an account, installing an app, or using a cloud drive. This post is less a launch announcement and more a build note. The interesting part was not drawing a QR code. It was deciding what the pairing model should promise, what it should not promise, and how to ...

Would you use a platform dedicated to recovery journeys? *I will not promote*

After a surgery, injury, or health diagnosis, would you use a platform dedicated to connecting with others going through the same thing? Why or why not? I recently got back surgery at 24 years old and was unable to really find anything or anyone I could really connect with online. That’s when it dawned on me there may be potential for an app for those to connect on recovery journeys. I know there is apps out there like PatientsLikeMe but I more so want to take the social media type angle and...

How much commission to charge for a new marketplace? I will not promote.

I’m a solo founder and currently handling everything myself. I’m trying to figure out the right commission structure. The platform uses Stripe connect for payments, so there’s already a payment processing cost of roughly 5-6% per transaction before I earn anything. My challenge is ...

Need motivation “i will not promote”

Hey guys, I’m a startup founder at the Pre-Seed stage. Things were going well, but since last week, I’ve been feeling mentally exhausted and unable to dedicate much time to my startup. Last Friday, I lost my grandfather, and today I received the news that my best friend has died. I want to work, but my body feels extremely tired, and I’m unsure if it’s mental or physical. All I do is scroll on my phone and stay in bed, wasting time. I need motivation from my fellow founders. Throw me some good...

Should your ICP of your mvp allow you to break even from pre seed? I will not promote

Preparing budget for pre seed stage. We have a few b2b customers on our MVP and looking to get a few more within a specific bracket. Slight snag, this bracket makes the economics of the ICP quite narrow. As a result, we would struggle to reach break even, if we were to stay within this bracket. The goal is obviously to address a larger customer bracket later on, when the MVP has progressed to a point where the product is ready for larger scale deployments. At the pace I see things progr...

My first hire as a founder lasted nine months. Looking back, I ignored a few obvious signs. I will not promote.

About 18 months after I started the biz, I needed someone to take over content and a bit of operations. She had a great portfolio and a reference, so I skipped the paid test project. Didn’t need the extra cost or hassle. The first month went well enough. Then deadlines started slipping and I realized I was reviewing almost everything before it went out. By month four, I was doing a big chunk of the work myself. What surprised me wasn't that it didn't work out, but how I kept convincing mys...

Is this the best strategy to build unique content now? i will not promote

Because of generative AI, any product that is virtual can be copied. This includes the copy, assets, and unique ideas. So, I was thinking that perhaps products now need to provide monthly, even weekly fresh content. For example, in a game, maybe you'd release a new level every month with new challenges, and offer a subscription model. That way, the unique pull is your own imagination and ideas, which is what users will keep coming back to you for. Other interesting AI-proof ideas might involve...
