Why HN links it
HN readers link this deep dive into the GIF format, which shows how an image can be built from 0s and 1s. One comment riffs on it with steganography tips and other file formats, without judging the post.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
This is a personal website of Dr. Pedram Hayati, a (Cyber) Security Researcher, Serial Entrepreneur, Lecturer, Keynote Speaker, and Baba.
