Experimenting with my Sketches and ControlNet
April 1st, 2023Lately I’ve been spent some time using ControlNet to process some of my sketches, the results are quite interesting and show the potential of the technology even when the starting sketch is very low quality and noisy, due to being on squared paper.
Can we show causation between a book genre and its quality?
May 14th, 2022Quality is subjective, true, but can we show that no matter the audience a fantasy book is always better than an horror book?

June 10th, 2017I’m currently reading Deep Learning, from Ian Goodfellow, Yoshua Bengio and Aaron Courville. While reading I got interested in calculating the determinant of a square matrix, I know there are many existing libraries to do that but the algorithm looked simply enough to give it a try.
Enabling browser BPG support using Service Worker

April 26th, 2015Lately I found myself spending a considerable amount of time playing with Service Worker.
