Btw I just put something up online that I spent a couple of evenings in my couch putting together: it's a website where you can track any numerical data on the web. Want to know how many Twitter followers you have?

It's hard to write code for computers, but it's even harder to write code for humans

Writing code for a computer is hard enough. You take something big and fuzzy, some large vague business outcome you want to achive. Then you break it down recursively and think about all the cases until you have clear logical statements a computer can follow.

Predicting solar eclipses with Python

As I am en route to see my first total solar eclipse, I was curious how hard it would be to compute eclipses in Python. It turns out, ignoring some minor coordinate system head-banging, I was able to get something half-decent working in a couple of hours.

Simple sabotage for software

CIA produced a fantastic book during the peak of World War 2 called Simple Sabotage. It laid out various ways for infiltrators to ruin productivity of a company. Some of the advice is timeless, for instance the section about “General interference with Organizations and Production”:

What I have been working on: Modal

Long story short: I'm working on a super cool tool called Modal. Please check it out — it lets you run things in the cloud without having to think about infrastructure. Scaling out, scheduling, containerization, using GPUs, setting up webhooks, and all kinds of other stuff.

We are still early with the cloud: why software development is overdue for a change

This is is in many respects a successor to a blog post I wrote last year about what I want from software infrastructure, but the ideas morphed in my head into something sort of wider.

Algorithms are breaking how we think

Today, Alec Watson posted a video titled “Algorithms are breaking how we think” on his YouTube channel, Technology Connections. The whole thing is excellent and very well argued. The main thrust is: people seem increasingly less mindful about the stuff they engage with. Watson argues that this is bad, and I agree. A little while ago I watched a video by Hank Green called “$4.5M to Spray Alcoholic Rats with Bobcat Urine”. Green has been banging this drum for a while. He hits some of the same notes as Watson, but from a different angle. This last month has been a lot, and I’ve withdrawn from news and social media quite a bit because of it. Part of this is because I’ve been very busy with work, but it’s also because I’ve felt overwhelmed. There are now a lot of bad-faith actors in positions of power. Part of their game plan is to spray a mass of obviously false, intellectually shallow, enraging nonsense into the world as quickly as possible. At a certain point the bullshit seeps in if you’re soaking in it. The ability to control over what you see next is powerful. I think it would be great if more people started being a bit more choosy about who they give that control to.
