- Yesterday we talked about how cheap code is fueling an era of idiosyncratic tooling, and previously we’ve talked about the rise of spec driven development. In that second piece, we ran through some of the initial examples of spec driven development with agents: By far, the...

- Introduction If you want to let users call your service from their own app. This is very possible. The hard part is not generating a key. The hard part is doing the full system well. Secure storage. O...
- Introduction Clean code always mattered. But now it matters more. AI reads your code. AI writes your code. The cleaner your codebase is. The better AI understands it. The better AI writes new code tha...

- TypeScript and Rust-Analyzer support a handful of quality of life, code navigation improvements. For example, if you try to go-to-definition on a variable in your IDE, but end up clicking the trailing comma, it still navigates to the variable. let a = 10 // ^ go-to-def...

- Howdy folks, can you believe that the year is over? Shocking! I spent December travelling around Sri Lanka with my family, and it was incredible! I published a few pics from our trip. I managed to catch up on a long reading list and, as I do every year, I published my annual...

- Jan Miksovsky lays out his idea for website creation as content transformation. He starts by talking about tools that hide what’s happening “under the hood”: A framework’s marketing usually pretends it is unnecessary for you to understand how its core transformation works — but...

- 8/5/2025 I'm somewhat obsessed with randomised testing. AFAIK, I'm the first consultant to do Deterministic Simulation Testing for a client. But when I am approached about implementing DST we quickly realize their existing codebase isn't ready for it; DST requires significant...

- I hate unrecognizable URLs. If I want to go back to a specific document or page, I should be able to type the name of it in the address bar and find it in my browser history. Notion is particularly good at this, and v0 was particularly bad at it (for a while), so this is what I...
- One of my pet peeves with testing in web development is mocking. So many devs tend to be purists who insist that the unit under test should be the only thing being tested, and that's why they mock everything. In projects that use Prisma or any other ORM, developers mock the ORM...
- TypeScript's type system can play DOOM. Surely we can make it do something useful for our projects too, right?...
- I quite enjoyed this talk. Some of the technical details went over my head (I don’t know what “split 16-bit mask into two 8-bit LTUs” means) but I could still follow the underlying point. First off, Andreas has a great story at the beginning about how he has a friend with a...

- Sometimes you have chunks of code you need to sync. For instance, in your backend you might have some validation that you want to sync with the UI. So you write: // Please keep in sync with api/routes/create_session.py! and a corresponding: # Please keep in sync with...

- I recently stumbled upon the term "vibe coding" through TikTok videos. It refers to using AI tools to generate code and drag-and-drop automation tools to handle business logic in apps. This trend leaves me with mixed feelings. While it's impressive to see people rapidly creating...

- One of the highlight features of Neovim 0.11 is the simplified LSP setup. My needs are pretty basic, so I moved things off the nvim-lspconfig to my configuration folder, uninstalled the plugin, and almost everything works like a charm. If you use plenty of LSPs and you...
