I am building a cloud

Today is fundraising announcement day . As is the nature of writing for a larger audience, it is a formal, safe announcement. As it should be. Writing must necessarily become impersonal at scale. But I would like to write something personal about why I am doing this. What is the goal of building exe.dev ? I am already…

How I program with LLMs

This document is a summary of my personal experiences using generative models while programming over the past year. It has not been a passive process. I have intentionally sought ways to use LLMs while programming to learn about them. The result has been that I now regularly use LLMs while working and I consider their…

The network started off using IPX over coax to a Novell Netware server, the fanciest software we ever owned. IPX was so much easier than TCP/IP. No DHCP and address…

Zero Trust Networks

I am leery of jargon. I am as guilty of using it as the next engineer, but there comes a point where there are just too many precise, narrowly-understood terms polluting your vocabulary. The circle of people you can talk to shrinks until going to the store to buy milk feels like an exercise in speaking a foreign…

Searching the Creative Internet

I had of late been lamenting the loss of the internet of the 1990s. A place where everything was obscure or new. If you saw something mainstream like a Disney princess, it was because someone had taken the time to handcraft an ASCII art portrait. Today if you type [disney] into the ubiquitous search engine , every…
