if you're wondering what I wrote my #RubyWorld toots on... it's my new Sony Xperia 1 VI and my trusty japanese bluetooth keyboard 3E-BKY8 plus the pebble mouse 2!
Using Android with a mouse makes things so much easier. Also either Sony or Stock Android made some nice improvements to multiwindow functionality

They solved the issue of how to make sure data migrates after changes, by using a feature flag, but check if the new and old orders are equal.
We love Ruby, we use it and we form the community and thats why we organize conferences.
We also have conferences in the US and Europe. its fun. and so we created gems and thus Rubygems. So we improved the language. 2001 in Tampa we had the first ruby conference there and we had people from 15 countries.
The amount of love is unique in the Ruby Community and that love made it a nice and friendly community. I am very proud of you. Ruby is great and it is OSS.
#RubyWorld Freee CTO on stage now talking about their journey from small startup to well known accounting and tax software.

Next up Mr. Hasumi from ANDPAD.
Ruby is fun. Why is ruby fun, because conferences is fun and because MINASWAN. #ANDPAD is a big part of Ruby Conferences (THANK YOU!) 3 Rubyists from ANDPAD traveled all over the world this year to conferences.
Now introducing ydah and other rubyists and their favorite ruby methods!
Matz now saying how he also wanted to do a overhaul of ruby in the early 00s with Ruby 2 *not 2.0, but he lost track, which was good, because perl and python had long migrations which took over 15 years. It was lucky that he didnt order or direct too much back then.
