Check out spelungit: An MCP server I wrote for semantic search of git history. Fully local using a local LLM and sqlite to store embeddings.

Plans to use stronger online models in the future, but for now, this works pretty well!

Spelungit: When git log --grep isn’t enough

Ever tried to remember why you made a change six months ago? I built Spelungit so you can search Git commit history with natural language instead of praying to the regex gods.

At every point in the universe, if you look out into space, the universe is expanding in all directions from that point. Every point in the universe is the center of the universe. So ma’am, in answer to your question if I think the world revolves around me, the universe does.

I think GitHub's CodeQL scanning is broken. It looks like every successive warning includes all the previous warnings.

I was trying to find an old router in my order history on Amazon and how did I order this before I was born?!

I recently adapted GitHub's scripts to rule them all github.com/github/scrip... to PostHog's existing bin scripts. Now it's a part of our handbook: posthog.com/handbook/eng...
And there's a repo: github.com/PostHog/scri.... I love the cross-pollination that happens when companies are transparent.

TIL a fact that’s obvious to any French speaking person but wasn’t to me. If it’s not a crescent shape then it’s not a croissant because croissant is literally crescent in French. It might be a viennoiserie instead.

I heard a scenario: Would you rather receive $1M dollars, or a penny on the 1st such that every penny doubles every calendar day.

Of course I pick $1M dollars. What'm I to do with 1 billion pennies? That wouldn't fit in my apt. It'd weigh over 2750 tons! I don't want that headache.

Do you work on a repo that squash and merges PRs? Notice that `git branch --merged` doesn't work in that scenario? Want a git alias that can clean up merged branches even if they've been squashed? Well I got you! An update to my GitHub Flow aliases: haacked.com/archive/2025...

Cleaning up gone branches

A git alias to clean up gone branches. Even ones that have been squashed and merged.

I now have an answer to the interview question, "What is the biggest technical challenge you've faced?".

Answer: Getting a React Native project to build and run locally. I now feel like I can handle any technical challenge!

Finished up some client sdk work in Ruby, and I don't like it as much as I used to. I really miss my types. I may have to look at introducing Sorbet into the library in the future.

Next stop is ... oh no ... PHP. God help me.

Wrote some Go finally. First impressions, I understand the appeal. It was quick to pick up, simple, and fast. Though I prefer rust for its richer type system.
