# An untagged page by Yukihiro Matz Matsumoto, 2025-06-15

## From the post on ruby.social

There, right at the front, just beneath the title and those gentle words that whisper who’s behind this masterpiece of a book (it’s why the lucky stiff, in case you’re still curious), you’ll find a little note from @matz addressed to  why:

It’s a note that feels like a secret handshake,
or a fox peeking out from behind a line of code.
