PNG and Hidden Pixels

Over the last few months, I've been seeing an increase in a third type of hidden pixels: PNG padding. Almost all of these sightings have been associated with steganographic challenges, capture-the-flag forensic contests, and similar puzzles. (Ever since people began staying home due to COVID-19, there seems to have been an increased interest in security, steganography, and related topics.)

The Three-Body Problem

Netflix on Tuesday announced that David Benioff and D.B. Weiss, the showrunners of HBO’s Game of Thrones, are working on an adaptation of Chinese science fiction author Liu Cixin’s The Three-Body Problem trilogy as their first major project since signing exclusive contracts with the streaming service last year.

“Liu Cixin’s trilogy is the most ambitious science-fiction series we’ve read, taking readers on a journey from the 1960s until the end of time, from life on our pale blue dot to the distant fringes of the universe. We look forward to spending the next years of our lives bringing this to life for audiences around the world,” reads the duo’s joint statement.

I look forward to this series as I enjoyed the three books a lot; I even recommended them to my friend Simon.
