Shipping a Neural Network on iOS with CoreML, PyTorch, and React Native
This is the story of how I trained a simple neural network to solve a well-defined yet novel challenge in a real iOS app. The problem is unique, but most of what I cover should apply to any task in any iOS app. That’s the beauty of neural networks.

Advantages of monolithic version control
Someone : Did you hear that Facebook/Google uses a giant monorepo? WTF! Me : Yeah! It's really convenient, don't you think? Someone : That's THE MOST RIDICULOUS THING I've ever heard.

Speeding Up Ruby with Shared Strings
It’s not often I am able to write a patch that not only reduces memory usage, but increases speed as well. Usually I find myself trading memory for speed, so it’s a real treat when I can improve both in one patch. Today I want to talk about the patch I submitted to Ruby in this ticket. It decreases “after boot” memory…

An opinionated guide to Haskell
For me, this month marks the end of an era in my life: as of February 2018, I am no longer employed writing Haskell. It’s been a fascinating two years, and while I am excitedly looking forward to what I’ll be doing next, it’s likely I will continue to write Haskell in my spare time. I’ll probably even write it again…

I still keep a couple of my favorite old smartphones. Sometimes I use one of them as my primary device for fun. Phones are among the fastest evolving markets, even a year makes a whole lot of differences. One of the biggest challenges with using old phones is the software: they don't run modern software.

An Introduction to Cache-Oblivious Data Structures
If you read my recent post about Postgres you may have noted that Postgres operates primarily with fixed-size blocks of memory called “pages.” By default, Postgres pages are 8KB.
