I program on the subway
Ever since moving to New York City, I've found my time to be in more demand than ever. Between work, meetups, and social events, I have noticeably less time for side projects than I had before moving here. At the same time, my commute is a massive time suck. It's 30 minutes each way, which doesn't sound that bad, but…

The Theatre of Pull Requests and Code Review
I recently attended the Goatmire Elixir Conf and one of the standout talks for me was Saša Jurić’s “Tell Me a Story” . It was an incredible presentation that combined theatrical storytelling with practical technical advice. Saša performed parts of his talk in character, turning technical topics into a compelling…

Things you can do with a debugger but not with print debugging
People do or do not use debuggers for a variety of reasons. For one thing, they are hard to setup in many codebases. Second, you can’t use them when your application is running on remote environments (such as kuberenetes). So, anecdotally, I have seen way more people using Print/ log.Debug compared to a debugger.

Async Queue – One of my favorite programming interview questions
For the past 7+ years, I've been conducting a programming interview that has been a true personal favorite of mine. It was passed down to me from good friends (Jeremy Kaplan and Carl Sverre, and it was the latter whom I believe invented it). This interview has probably been

Shardines: SQLite3 Database-per-Tenant with ActiveRecord
There is a pattern I am very fond of - “one database per tenant” in web applications with multiple, isolated users. Recently, I needed to fix an application I had for a long time where this database-per-tenant multitenancy utterly broke down, because I was doing connection management wrong. Which begat the question…

Baba Is Eval
Baba is You is a sokoban puzzle game where the rules themselves have to be manipulated to win. (For the uninitiated, the store page should explain the idea best.) The level of abstraction required to solve most levels makes it a formidable reasoning benchmark, with many reasoning steps being completely orthogonal to…

Rust to C compiler – 95.9% test pass rate, odd platforms
