We’re building a public cloud, on hardware we own. We raised money to do that, and to place some bets; one of them: GPU-enabling our customers. A progress report: GPUs aren’t going anywhere, but: GPUs aren’t going anywhere. A couple years back, we put a bunch of chips down on the bet that people shi...

I was talking to a friend about how to add a directory to your PATH today. It’s something that feels “obvious” to me since I’ve been using the terminal for a long time, but when I searched for instructions for how to do it, I actually couldn’t find something that explained all of the steps – a lot o...

Shell scripts sometimes have to append data to a file. Redirecting output with >> is the conventional way and works fine, but using tee -a instead is a usually better default, especially in continuous integration. It’s just as easy and gives automatic introspection: the same value is printed to stdo...

These are wild times. It’s now possible to describe a fancy app in a single text prompt, e.g., “Make an AI recipe generator with ChatGPT that lets me enter a food, generate recipes and save my favorites to a gallery for later” And watch a complete app materialize in seconds: If you’ve been playing w...

I cannot count the number of times in my career I wished I could run JS in response to CSS property changes, regardless of what triggered them: media queries, user actions, or even other JS.
