> HELLO!

The kind of note you write standing up, in a hurry, because the next talk is about to start and you want the book to remember you were there. A 
fox stamps it "FOUND" and files it under the registry, somewhere between a lost umbrella and a chat about #Sorbet and #tapioca

The amazing @yujiyokoo gave a piece of advice that is also a way of life:
> Make whatever you want! Never mind the trend!
> Yuji Yokoo
Yuji has been doing cool things with #Ruby for a very long time, and after that long you learn that the trend will move on and the thing you actually wanted to build will not. A fox nods, ignores the latest trends entirely, and goes back to making something weird for his #SEGA #megadrive / #genesis.
In green, boxed neatly on page 173, @edouard_chin made a reference to the #polish #Ruby community:
> The dragon of #Krakow is that strong :)
> Edouard Chin
> Kaigi 2026
The Wawel #dragon, the Smok, that strong. Edouard slid a Polish legend into a @rubykaigi note. A fox tips its hat to the cross-cultural mischief.

Big bold pink capitals fill page 176, all the way to the gutter. @andrzejkrzywda, for the Polished #Ruby Team:
> RubyConf Thailand 2026
> The Polished Ruby Team
> Dla Alexa z Szacunkiem
> Andrzej
The Polish(ed) Ruby Team, written in the least polished, most enthusiastic block letters imaginable, which is somehow the most respectful thing of all. A fox salutes the Polish delegation at @rubyconfth.

Right where the book pits a Rabbit against a ScubaArgentine, @peterzhu2118 left a tiny compliment in Japanese:
> すごい！日本語上手。
> @peterzhu2118
Peter, the #Figma #Ruby core committer who spends his days teaching the GC new tricks (variable-width allocation, Object Shapes, the things that quietly make every #Rails app a little faster), took a moment off from compacting the heap to write here.

Right on the Method Missing page, @mame, Ruby committer, #TRICK champion, the man who made a #Quine Relay across 128 languages, signed in with a tiny program:
> eval$s=%!puts"eval$s=%"<<33<<$s<<33
> # Yusuke Endoh!
A self-printing Ruby one-liner. A #quine, written in a guestbook, by hand. Because that's how a fox who breathes obfuscated #Ruby leaves their name.

Short and sweet, on page 202:
> #rubyfriends
> Masafumi Okura
One hashtag, written by @okuramasafumi's hand, in a paper book. That's commitment to the bit. A fox would absolutely tag its friends if it had thumbs and a phone.
And the fox would attend to @kaigionrails as well.

On page 236, with a comic about adding a dividing slash to arrays, @eregon left a blessing with a little drawn gem:
> May the Truffle of a 
be with you!
> @eregon
The @truffleruby maintainer himself, wishing you the Truffle. The comic insists "RUBY doesn't come with this method! And skeletons don't come with beards. But wizards do!" A fox, neither skeleton nor wizard, accepts the truffle and moves on.

Across the spread on page twenty-nine, the man behind @JRuby left his blessing in bright pink:
> Ruby and JRuby, friends forever! Keep Ruby Chunky!
> Charles Nutter
@headius would have it no other way.

Right where the book says "Kon'nichi wa, Ruby" and two foxes perch on the chapter rule, @ioquatix slipped in an #Async reference:
> Async do
> puts "Hello World!"
> end # Samuel Williams
The fellow who taught Ruby to do a thousand things at once, and what does he leave us? A polite hello. Even the busiest #fiber waves on its way past.
