just before dawn is my favorite time. it's always so beautiful, with so many little joys to experience, with light and color just teasing the horizon, rabbits running about before they'll be seen, a not quite quiet that hints at the day's potential.

If you're a Mac person who uses Windows (by choice or by fiat) and WSL, take a look at this github.com/shanselman/M... and let me know what you think. It takes your WSL (or a new one) and makes it as "Mac Comfortable" as possible with things like HomeBrew, zsh, starship, etc. File Issues with ideas.

The moon going from full moon to a red moon and starting to go back to a normal full moon, then my camera battery door fell off.

The moon going from full moon to a red moon and starting to go back to a normal full moon, then my camera battery door fell off.

Here's my first edit on the March 3rd Lunar Eclipse. 15 moon shots, 1 foreground. Taken over a 3 hourish period.

Picture of Marjane Satrapi alongside a quote from her. The quote reads:

The world is not divided into countries. The world is not divided between East and West. You are American, I am Iranian, we don't know each other, but we talk together and we understand each other perfectly. The difference between you and your government is much bigger than the difference between you and me. And the difference between me and my government is much bigger than the difference between me and you.

And our governments are very much the same...

- Marjane Satrapi, Iranian-French graphic novelist

Thinking about this quote from Persepolis creator Marjane Satrapi again.

From Problem to Taxonomy An introduction to content-defined chunking: why fixed-size splitting fails, how content-aware boundaries solve the deduplication problem, and a taxonomy of three CDC algorithm families.

Sharing a 5-part series on content-defined chunking (CDC) algorithms as background research for my master's thesis on source code deduplication. It's a tour of the algorithms, a deep dive into FastCDC, and explores costs for building deduplication pipelines at scale.

ASTRAL Research Preprint A research preprint on ASTRAL, an architecture for code generation that frames program synthesis as energy minimization over a constraint-shaped landscape.

i couldn't sleep last night (thanks, cats!), so i used the time to finish editing the research preprint on ASTRAL, an architecture for code generation that frames program synthesis as energy minimization over a constraint-shaped landscape: nulldivide.com/blog/astral-...

Graph Salience + Agentic Context Behavioral analysis finds code that changes. Structural analysis finds code that matters. Combining them gives agents something neither provides alone.

understanding a code base is crucial for an agent to operate on it appropriately, but most systems struggle to provide that understanding. homer combines structural graph analysis with behavioral signals into a code insights graph optimized for both agents and humans.

can't sleep? just work on more Lean formalisms of your constraint algebra. can always find more holes in those holes.

Turns Out There Was Voter Fraud in Georgiaβ€”by Elon Musk The state board of elections found Musk’s PAC sent prefilled ballot applications.

The story that Elon Musk committed voter fraud has gotten next to no coverage -- one of those things you can't make come up on a Google search.

But I think it's time for Dems to go on offensive abt right wing coddling of this immigrant interfering in our elections.

Energy, Structure, and Shaped Generation On ASTRAL, energy-based models, and what code generation looks like when you stop predicting and start satisfying constraints.

I've been working on shaped generation for quite a while, and seeing Logical Intelligence's recent updates about their progress with energy-based models has me super excited about the future of this space, so I wrote up more thoughts about it all: nulldivide.com/blog/energy-...
