Typing the technical interview
In the formless days, long before the rise of the Church, all spells were woven of pure causality, all actions were permitted, and death was common. Many witches were disfigured by their magicks, found crumpled at the center of a circle of twisted, glass-eaten trees, and stones which burned unceasing in the pooling…

Evidence Based Scheduling
Software developers don’t really like to make schedules. Usually, they try to get away without one. “It’ll be done when it’s done!” they say, expecting that such a brave, funny zinger will reduce t…

Reflecting on one very, very strange year at Uber
As most of you know, I left Uber in December and joined Stripe in January. I've gotten a lot of questions over the past couple of months about why I left and what my time at Uber was like. It's a strange, fascinating, and slightly horrifying story that deserves to be told while it is still fresh in

The Perils of JavaSchools

Painless Functional Specifications

Designing for People Who Have Better Things To Do With Their Lives
When you design user interfaces, it’s a good idea to keep two principles in mind: Users don’t have the manual, and if they did, they wouldn’t read it. In fact, users can’t r…

Five Worlds
Something important is almost never mentioned in all the literature about programming and software development, and as a result we sometimes misunderstand each other. You’re a software develo…

Options vs. Cash
I often talk to startups that claim that their compensation package has a higher expected value than the equivalent package at a place like Facebook, Google, Twitter, or Snapchat. One thing I don’t understand about this claim is, if the claim is true, why shouldn’t the startup go to an investor, sell their options for…

Good at programming competitions does not equal good on the job [video]
A couple of days ago I watched a How Computers Learn talk by Peter Norvig. In this talk, Peter talked about how Google did machine learning and at one point he mentioned that at Google they also applied machine learning to hiring. He said that one thing that was surprising to him was that being a winner at…

Acing the technical interview
If you want to get a job as a software witch, you’re going to have to pass a whiteboard interview. We all do them, as engineers–often as a part of our morning ritual, along with arranging a beautiful grid of xterms across the astral plane, and compulsively running ls in every nearby directory–just in case things have…

On average, skipping college and investing tuition costs nets a higher return
We've all heard how expensive college is getting, along with plenty of criticism surrounding its value in a changing job market. Of course, there are many benefits beyond the monetary ones that should be considered when exploring college options, but for the purpose of this post I'm going to limit the scope and purely…

Engineering management lessons (2014)
Welcome to engineering management. It’s fun, it’s exhausting, it’s rewarding — but most importantly it’s new! What worked for you before won’t work now. You’ll have to acquire a new set of skills, and shed some bad habits in the process. Here is a short guide to get you started.

Uncle Bob and Silver Bullets
A while back I wrote that Robert Martin was ruining software by being too good at programming. That was supposed to be a joke. Since then he’s done his damndest to actually ruin software by telling people they’re doing it wrong. His most recent response where he yells at software correctness was the breaking point for…
