Screaming Frog Gave Me 10,000 Errors. Here

I ran Screaming Frog on a client's 4,000 page e-commerce site. It came back with 10,247 issues. I stared at that number and immediately wanted to close my laptop and go outside. 10,000 issues. Where do you even start? Turns out, after spending two full days triaging everything, only about 10 of those issues were actually impacting rankings or traffic. The rest were technically "issues" according...

AI Agents and ADHD Brains Break in the Same Ways

I built an API in C, couldn't document it, so I accidentally created an open-source tool

It started with C and suffering A while back I built an API in C. Yes, C — I am weird, I know. Using Mongoose — an embedded HTTP server library for C/C++ by Cesanta (not to be confused with Mongoose.js, the Node ODM). Every route, every handler, every response — written by hand. No framework. No annotation type system. No decorators. When I was done, I went looking for a documentation...

Git for AI Prompts: Why Your Team Needs Prompt Version Control Right Now

If you're shipping AI features in production, you have a problem you probably haven't named yet. Your prompts are everywhere — hardcoded in source files, pasted into Notion pages, buried in Slack threads from six months ago. When something breaks, you have no idea what changed. When someone "improves" the system prompt on a Friday afternoon, you find out on Monday morning via a support spike. We...

Jog Squad | A Gamified Eco-Jogging App: Fix the Earth. Fix Your Health. One Run at a Time. 🏃

This is a submission for Weekend Challenge: Earth Day Edition I'm a jogger. Not the "I ran a marathon once" kind but the "I need to run or my brain stops working" kind. Running is how I think, how I decompress, how I stay sane. But here's the thing that drives me crazy: every single run, I pass litter. Plastic bottles in the grass. Wrappers caught in fences. Cans rolling down the sidewalk. I...

PostgreSQL High Availability: A Practical Guide with Patroni and pgBouncer

Introduction Your database is the last thing that should go down. Yet setting up PostgreSQL for high availability remains one of the most under-documented areas in the DevOps world.

Cross-Examination in a Click: Using AI to Uncover Witness Inconsistencies

For the solo criminal defense attorney, reviewing discovery is a monumental task. Manually comparing hundreds of pages of witness statements for contradictions is time-consuming and prone to human error. What if you could automate the initial analysis, letting AI flag the critical discrepancies so you can build a sharper case strategy? The core principle is moving beyond simple summarization to c...

The Restore Path Is the Most Neglected Part of Backup Design

The restore path is where backup architectures fail — not the backup job, not the retention policy, not the storage tier. This is not an operations failure. It is a design omission. Most architectures are designed to write data — not to get it back. The Backup Job Is Not the Goal Most backup architectures are designed around the protection plane — backup jobs complete, retention wind...
