I Built a Tool That Cuts Windows Setup Time From 4 Hours to 2 Minutes

Every developer has lived this nightmare. You fresh-install Windows. You open Chrome, go to the VS Code website, download the installer, click through the wizard. Then Git. Then Node.js. Then Python.

Astounding Stories of Super-Science, April, 2004 - Table of Links

It highlights a lost civilization that has evolved in complete darkness, abandoning sight as a sense and developing a society shaped entirely by touch, sound, and adaptation. The story explores perception, evolutionary change, and the limits of “normal” human experience.

If you are building a retrieval-augmented generation system for a higher-education institution, your pipeline is probably violating FERPA.

This post covers five rules that most enterprise RAG imple...

HOW I AUTOMATED MY DAILY WORKFLOW USING AI (AND GOT MY TIME BACK)

Every morning, I used to wake up feeling like a productivity machine. “This is the day. I’m getting everything done.” Then I open my laptop… One email turns into ten. One quick reply turns into a full conversation my notes look like something written during an earthquake and somehow, two hours are gone… just like that. At some point, I had to ask myself a very serious question: Why am I doing al...

Why Queues Don’t Fix Overload (And What To Do Instead)

This post is about the physical laws of backpressure in software systems, latency death spirals, and why unbounded queues are a bug.
