Finding a 27-year-old easter egg in the Power Mac G3 ROM

This ROM was used in the beige desktop, minitower, and all-in-one G3 models from 1997 through 1999. As I write this post in mid-2025, I’m having a really diff

Making TRAMP faster

I recently changed jobs and found myself in a position where I would need to do a lot of work on remote machines.

Since I would be using it all day now I figured I should take some time to make it faster.

Apple Research just unearthed a forgotten AI technique and is using it to generate images

Today, most generative image models basically fall into two main categories: diffusion models, like Stable Diffusion, or autoregressive models, like OpenAI’s GPT-4o. But Apple just released two papers that show how there might be room for a third, forgotten technique: Normalizing Flows. And with a dash of Transformers on top, they might be more capable than previously thought. First things first: What are Normalizing Flows?
