I am pleased to announce that we will have a booth at RubyKaigi 2025 (at Ehime Prefectural Cultural Center). If you happen to see us at the venue, we would be happy if you could use the opportunity for communication with friends, colleagues, or people you will meet, as well as for discovering new books (and maybe killing time, too)!

We are accepting your recommendation for the listing books (see the above page to reach the submission form). Thanks!

Thank you for your github sponsors <https://github.com/sponsors/ko1/>. Now I run 8 machines <https://dev.to/ko1/personal-efforts-to-improve-the-quality-of-ruby-interpreter-2lcl> in my house to maintain ci.rvm.jp CI environment to find out ruby's bugs and we found many failures/errors this year too. Thanks again for your support.

Happy black Friday and you only need $1! https://github.com/sponsors/ko1

Thank you for many GitHub sponsors! https://github.com/sponsors/ko1 Thanks to your support, I can add a new machine called ruby-sp3. It is the smallest but the fastest! Now this machine is running many tests http://ci.rvm.jp/results/trunk@ruby-sp3

👋 I will have a workshop at RubyConf 2023 to show you how RBS and Steep can help your Ruby development.

I will give you a sample application with RBS type definitions and Steep setup. Through some coding exercises, you will learn how the type checking helps you (and bothers you too...)

RSVP to join the workshop!

Thankfully, we will be able to continue Ruby development at STORES <https://st.inc>. During our job search, we consulted with many people and received many warm words of encouragement. I would like to take this opportunity to thank them.

An oracle gave me an inspiration to make some kind of cloud-like icon, and PowerPoint granted it to me.

* QRCode https://qr.quel.jp/text.php で SVG をつくる
* PowerPoint でゴニョゴニョ

でできた。PowerPoint すごい。
