Recently I tried Fooocus by Lyumin Zhang (Illyasviel) which fulfills its promise to allow one to “Focus on prompting and generating” - it is certainly easy to use! But shortly after its release, someone has “ported” the code to ComfyUI as a Custom Node! So of course it’s time to test it out...

The Stability AI documentation now has a pipeline supporting ControlNets with Stable Diffusion XL! Time to try it out with ComfyUI for Windows.

In this post, I experiment with latent scaling and latent compositing with SDXL 1.0 using ComfyUI. That is to say, increasing / decreasing the size of the image, and combining multiple images into one à la green screen (chroma key) compositing.

SDXL 1.0 uses two text prompts used to guide image generation. In my first post, SDXL 1.0 with ComfyUI, I referred to the second text prompt as a “style” but I wonder if I am correct. I have no idea! So let’s test out both prompts...

Onward with SDXL and ComfyUI! Sometimes I want to tweak generated images by replacing selected parts that don’t look good while retaining the rest of the image that does look good. Rather than manually creating a mask, I’d like to leverage CLIPSeg to generate a masks from a text prompt.

Yesterday I mentioned in passing that my Nvidia RTX 2060 with 12GB could not run both SDXL 1.0 Base and Refiner models in a single ComfyUI workflow. Today, I show you my workaround and also experiment with adding the SDXL 1.0 Official Offset Example LoRA to the workflow.

Stability.ai has released Stable Diffusion XL (SDXL) 1.0 (26 July 2023)! Time to test it out using a no-code GUI called ComfyUI!

A short post about setting up a mouse on macOS to mimic trackpad gestures.

May I present to you: my second LEGO Space MOC, the Blacktron Star Fighter! This is an alternate build using only parts from set 40580: Blacktron Cruiser.

In my previous post, I managed to get Whisky, with Apple’s Game Porting Toolkit, working on macOS Ventura without Homebrew. Here I manage to get Steam running after jumping through hoops.

A long time ago, I compiled Wine from scratch on 32-bit macOS Sierra. I lost interest because I never used it. Now after WWDC 2023, everyone is talking about the happy side effect of Apple’s Game Porting Toolkit (GPTK) which uses Wine under the hood to run Windows 10 DirectX 12 games on macOS!

Want to check your connected bluetooth device battery level on a mac? Here is one way: using xbar (I am aware there are a bunch of other xbar plugins to do something similar, but I’ve been using my own script before I ever used xbar).

Did you know that macOS has a built-in game performance HUD with a frames per second (FPS) counter, similar using RivaTuner Statistics Server (RTSS) to display a GPU performance overlay in Windows? Here’s how to enable the Metal Performance HUD.

Some time ago, I explained how I setup “Global hotkeys for macOS with skhd”. I mentioned running it automatically upon login via the macOS Launch Daemon but did not detail the steps. So here they are...

I have been using UTM on M1/M2 macs for all my virtualization needs for a while, but never posted much because it practically works out of the box. Since around October 2022, UTM v4.0.9 on macOS Ventura allows Apple Hypervisor Virtualization Virtual Machines to use Rosetta 2.

I was recently researching external storage for my Mac, looking for the “fastest” and most “reliable”. There are so many options, and of course, so many different price points! It’s all very confusing: NGFF M.2? NVMe M.2? USB 3.1 Gen 1 (5 Mbps)? USB 3.1 Gen 2 (10 Gbps)? USB 3.1 Gen 2x2 (20 Gbps)? Thunderbolt 3? Thunderbolt 4? USB 4.0?

Recently (around 14 December 2022), Apple’s Machine Learning Research team published “Stable Diffusion with Core ML on Apple Silicon” with Python and Swift source code optimized for Apple Silicon (M1/M2) on Github apple/ml-stable-diffusion. Here I’m trying it out on a MacBook (though the code also works on iPhones and iPads)...

Did you know the macOS Printer service (Common UNIX Printing System, or CUPS) keeps a copy of every single print job ever? Here’s how to change this default behaviour.

Following from my previous post, AI-generated images with Stable Diffusion on an M1 mac: This time, using the image-to-image script, which takes an input “seed” image, in addition to the text prompt as inputs. In this case the model will use the shapes and colors in the input image as a base for the output AI-generated image.

There has been a lot of buzz about Stable Diffusion for text-to-image synthesis, which saw its Public Release around 22 Aug 22. You can read more on the Stability.AI blog and try it at Hugging Face. What’s groundbreaking is is that is open source, with a pre-trained downloadable model and modest system requirements, so anyone can try it on their own computer... anyone... like me!
