As soon as GitHub Copilot burst onto the scene, everyone started asking, “How do we teach Copilot about our platform?” Whether you’re building a managed Postgres service (like Neon) or a specialized set of APIs, it’s no longer enough to rely on devs hunting through documentation. They want AI-driven...

In this blog post, we look at how can make things “read-only” in TypeScript – mainly via the keyword readonly.

Experimentation at Deliveroo has significantly boosted our innovation as a company. It has allowed us to explore new ideas, protected us from unforeseen challenges by preventing wasted time and resources on ineffective initiatives, and promoted intellectual honesty by validating our assumptions. Ove...

A few weeks ago I ran a terminal survey (you can read the results here) and at the end I asked: What’s the most frustrating thing about using the terminal for you? 1600 people answered, and I decided to spend a few days categorizing all the responses. Along the way I learned that classifying qualita...

As beautiful as a greenfield database is, it’s useless without data. This is not just for production–tests, development, staging, and demos–all need data for proper functionality. This is where seed files come in. Seed files are scripts that populate your database with initial data: admin roles, ini...

If you’ve been keeping up with the Neon story, we introduced database branching in December 2022. Our instant branches—complete copies of production, including data and schema—have enabled thousands of developers to work and test efficiently within the safety of their own isolated environments. Neon...

Trigger warning: incredibly wonky theoretical cryptography post (written by a non-theorist)! Also, this will be in two parts. I plan to be back with some more thoughts on practical stuff, like cloud backup, in the near future. If you’ve read my blog over the years, you should understand that I have ...

Imagine your AWS RDS Postgres database scales to 100 TB. Now, sh*t disaster happens—your production instance experiences a critical failure. How would RDS handle different failure modes? And how long would it take to restore full production capability? Production failure modes Production teams commo...

I've started working on a new edition of Ruby Under a Microscope that covers Ruby 3.x. I'm working on this in my spare time, so it will take a while. Leave a comment or drop me a line and I'll email you when it's finished. RUM includes a series of “experiments:” simple code snippets that show eviden...

During the last two years, ESM support in TypeScript, Node.js and browsers has made a lot of progress. In this blog post, I explain my modern setup that is relatively simple – compared to what we had to do in the past:

A lot of us as developers have hi-DPI screens, and we can easily forget to test the websites we build on low-DPI screens. One common issue I noticed is that thin font weights can be hard to read on low-DPI screens. Since there are fewer pixels to render details, fine lines can appear blurry due to a...

An AI is not inspired because a computer doesn't have a soul.AI has a limited ability to inspire.Humans are better-inspired by other inspired humans.The human soulHumans have an inner spirit. When we give expression to our inspiration, we create in the world what had started on the inside. My though...

Most developers know about red teams: a specific group of people chosen to be the antagonist to your system, trying to sniff out vulnerabilities in your code or organization. Basically, like Sneakers, or the annoying plotline in The Newsroom season two. (Someone should have really red team’d Sorkin ...
