    • Comfy UI Setup On AWS

    I setup a comfy UI rig on an EC2 instance to play around with image generation using open source Flux, SDXL models and LoRAs. While setting up manually was excruciating, it was a good learning curve.

    LoRA Training

    Most multimodal GPTs were not able to generate the new Hyundai Tucson model with the new wing-like DRLs. I trained a LoRA model using Flux that generates accurate Hyundai Tucson renderings.

    (More) About Me

    I'm proud to belong to the LimeWire, Napster and Bonzi Buddy era of computing. I cannot do without tech. I've dismantled laptops and PCs for fun, or just to put thermal paste when it got too hot for gaming. I've overclocked CPUs and burnt cooling fans. I've reset BIOS passwords to get into password protected PCs. I've setup media file servers on raspberry pis. I've flashed custom ROMs to make old phones run faster. I've modded PC games because, why not?

    I discover music and genres from Movies and TV Shows only. I detest today's music. I'm loyal to Oasis, Fuel, Semisonic, Dishwalla. Dr Dog, Stephen Sanchez, Cigarettes After Sex are cool though. If it's new music, it has to be acoustic or lo-fi covers of good ol rock n roll noise (Tame Impala, Chezile, Torre Florim).

    Blog

    I blog about things I find interesting in tech and AI. I also showcase my passion projects. I'll opine and rant, even.
