I've had komoroske.com/sudoku running for more than 8 years now, and users have solved over 800,000 puzzles in that time. I've never been particularly happy with the quality of the puzzles deployed on the site, and for the past couple of years I've been idly working on a sudoku generator written in go--mostly in the downtime on flights. The goal is to take all of that historical solve data to train a model that will give accurate ratings of a puzzle's difficulty.

The library is still really rough and there's a lot more I intend to do, but last week I rolled out the first (experimental) set of puzzles on my sudoku site to get more data to train the model, so I figured now was as good a time as any to open source it.

It's worth reading the post that Gruber is responding to--it's a succinct argument that I find compelling about why expectations for the Apple Watch are too high.

But Gruber's response to it is amazing: " I’m far from convinced that I’m going to find Apple Watch useful. I’m convinced more by Apple’s public and private confidence in it than by what they’ve revealed so far."

... Behold, the power of cultish devotion to a brand.

Today I learned why digital projections, especially if my eyes are moving, sometimes have this weird, stuttery look where the Red, Green, and Blue all break down.

The effect is called the Phantom Array effect (and for digital projectors, it's specifically called the DLP rainbow).

This happens when your eyes are moving because each red, green, and blue frame will hit your retina at different places that don't overlap. It happens more often in your peripheral vision because the Flicker Fusion Threshold is lower there.

Did I get that right?

I love learning about the complexity hidden behind seemingly straightforward things. 500,000 for a seat? Crazy!

This is some of the best writing I've seen in a very long time, and it's about design patterns. It's insightful, clever, clear, and just about perfect in every way. It should be required reading for anyone who has ever written code.

Even the margin notes are awesome: the point about loading up the program into your brain to reason about it literally being an OCR process blew my mind a bit.

We just updated polymer-project.org with a new look, new logo, and new beginner content. We're now officially in "alpha"!

I've spent a lot of times in the past few days reading the back catalog of stratechery. I find the author to be always interesting and often insightful--he's great at combining microeconomic theory, rigorous analysis, and a good understanding of the tech industry.

Yup, this is almost precisely my worst nightmare.
