Using Git Worktrees for Parallel AI Agent Development

Git worktrees are a lesser-known feature of git that only really became useful as CLI coding tools became really popular. They enable "duplicates" of a git project to exist on your file system that share the same .git database. This enables stashes, branches, etc to be shared across all worktrees. Since the folders + files are duplicated, this enables you to have different test environments, databases, env config, etc so multiple coding agent sessions can be run in parallel. However, switching between and creating git worktrees is a pain. The syntax is cumbersome, there are no great CLI completions, and it’s not supported within tools like forgit…

The Future and AI, Part 1

Introduction I’m in the midst of hunting for the next startup idea, and I’ve been thinking about and playing around with AI nearly every day over the last year. I’ve had a lot of conversations with fellow technologists about how the advances in AI are going to change our world, and I wanted to get some of them down on paper. I’d love to hear critiques and comments on any of these thoughts! I’m still revising my thinking here and would love to hear different points of view. How Will AI Improve? It’s impossible to predict exactly how things will play out, but it’s important to at least define a point of view and think about the categories where AI may or may not improve: Cost. Undoubtedly, inference costs will drop…

What I’ve Learned Searching for a New Startup Idea, Part 3

This is part 3 of a series of blog posts (here’s part 1 & part 2) about what I’m learning as I hunt for a new startup idea to work on). PE Rollups Create Opportunity Private equity is rolling up every industry you can imagine 1 . Plumbers, electricians, dental offices, primary care offices, machine shops, lawn businesses, RV parks, and software. PE is brilliant at extracting returns from an unoptimized business. It’s bad at focusing on the customer and building a great product. As industries roll up, prices increase, the quality of service decreases, and opportunities for a new disruptor at the bottom of the market emerge. Why does this happen? When PE acquires a business, the original founders lose motivation…

Categorizing Personal Email Contacts with AI

For years I’ve wanted to send out a yearly update (digital Christmas card of sorts) email to friends, both new and old. One of the problems is I don’t have a good address book that indicates who is a personal or work contact. I’ve been playing with datasette and I thought it would be fun to index all of my past emails and have AI categorize if they are a work, personal, or vendor contact. Importing Emails The first step is importing your emails from gmail into a local database. The easiest way to do this is to use a combination of Google takeout and a datasette plugin (note that it’s easiest to use my fork of the datasette plugin, the original package is dead)…

Using ChatGPT to Convert LabCorp PDFs into a Google Sheet

The last couple of years I’ve monitored my food, blood levels, etc more closely. It’s a topic for another blog post, but it’s been really interesting to watch how key blood levels have changed over time and reacted to changes in my diet and exercise. I use lab core for all my blood work, and I’ve been relatively happy with them. However, their online portal does not allow you to download a CSV or Excel document of your blood work over time. They only offer a PDF download. This makes it challenging to track your levels over time and understand what’s changing and why due to lifestyle changes. Enter ChatGPT. With the latest vision models, you can use it to extract tabular data from the unstructured PDF that LabCorp provides you…

Scraping the web with OpenAI

One of the really interesting LLM use cases is extracting structured data from unstructured data. In the old days (6mo ago), extracting structured data from web pages required custom xpath or css selectors for each website that constantly broke as the host changed their page structure. For instance, extracting the price of a house on redfin. This is why Plaid (and similar competitors) break so often: many of their integrations "screen scrape" which means they need a team of people updating xpath and css selectors on various bank sites (TreasuryDirect, for example, is broken constantly). I built a open source database of venture capital firms that used this approach to extract team member information from each firm…
