Joe Bertolami writes bertolami, a personal blog at bertolami.com about programming and ai. Since 2014, 15 different Hacker News readers have linked it 42 times, most often “Perceptual Image Hashing”. No feed was found, so read it on the site itself.
Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers link Joe Bertolami's blog for intuitive explanations of the Fourier transform and its use in compression, and cite posts on adaptive binary arithmetic coding and Claude Code benchmark tracking.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Joe Bertolami's portfolio and blog covering artificial intelligence, game development, computer graphics, data compression, and more.

HN discussionDoes this use a claude subscription or key, and has the account been used for anything else that day? On HN a few days ago there was a post suggesting that Claude gets dumber throughout the day: https://bertolami.com/index.php?engine=blog&content=posts&de...
