Hi all,
Recently, a doujinshi event called Gijutsushoten 19 (技術書典19) was held in Japan.
https://techbookfest.org/event/tbf19
For those unfamiliar with the term: doujinshi are self-published indie books created out of personal passion rather than commercial aims. They aren’t limited to comics or fan works – many are non-fiction, technical, artistic, or entirely original works. Gijutsushoten is an event dedicated exclusively to technical books, and this was its 19th iteration.
I participated as an exhibitor and published a doujinshi about SymPy, so I’d like to share it here.
Python Refactoring Practice: A Practical Walkthrough of Refactoring SymPy
(Python リファクタリング実践記 SymPy をリファクタリングしてみた)
https://techbookfest.org/product/sSYNxpHxmLs9R4cXPeHNah
Note: The book is written in Japanese, so I’m sharing this mainly for your information.
Regarding the proceeds, although modest, I have donated them through NumFOCUS. I wish for the continued growth and success of SymPy.

This is awesome.
I really think it's important for us as software practitioners to
write and reflect about our technical work, whether that's in books,
blog posts, or even just commit messages. It sounds like doujinshi are
also a great avenue for this sort of thing in Japan.

Thanks, Aaron.
In Japan, it sometimes feels like the overall motivation to contribute to OSS is relatively low.
In the past, the language barrier made participation seem difficult, but with the arrival of LLMs, that obstacle has become much smaller.
I'm just an ordinary programmer who doesn't speak English, yet I want to show that even someone like me can contribute.
I hope this helps more people realize how accessible contributing can be, and that it encourages wider participation in SymPy and OSS in general.
