Chinese, Japanese, Korean (CJK) users need different features than other languages. Language and culture dependent features and usage are important for productivity software such as LibreOffice. This talk will introduce some recent problems encountered in the CJK user environment of LibreOffice and how to improve them. Patterns of CJK language specific problems can be common across different software. Therefore, it may be applicable to other smartphones and desktop apps as well. The LibreOffice project is an aimed at multilingualism, as stated in The Document Foundation’s “Our Values” of “Our Next Decade Manifesto” that anyone can translate so that everyone can use it in their mother tongue. https://www.documentfoundation.org/pdf/tdf_manifesto.pdf However, LibreOffice developers are mostly in Europe, and in order to use them conveniently in other languages, those who understand those languages need to solve the problem. LibreOffice 's CJK and problems unique to the Japanese environment are various such as vertical writing, external characters, phonetic, currency and date notation. Of course, LibreOffice has various functions and problems for languages other than CJK. Typical examples are RTL languages that writes characters from right to left. Sometimes CJK regression bugs occur in the LibreOffice project. It is important to strengthen user’s feedback loop approach. We have to be able to explain it to people from different cultures. It is also important that CJK people actually try to fix the CJK bugs. From COSCUP 2019, I introduced typical CJK bugs every year. In this talk, I will present some of the major recent issues and episodes in CJK environment. I will also introduce the efforts of the RTL language community and the TDF initiative.

How PostgreSQL extensions work and how to get started developing extensions.
PostgreSQL is an open-source software RDBMS that is popular worldwide, and one of the main features of PostgreSQL is its extensibility. Extensions allow users to add functionality and customize PostgreSQL exactly as they want.
When using PostgreSQL with extensions, you may have wondered how extensions work or wanted to develop your own extensions.
In this talk, I will talk about how PostgreSQL extensions work and the first steps to start developing one. The target audience for this talk is anyone interested in PostgreSQL extensions or developing their own. I hope that this talk will be helpful for anyone who wants to get involved in the PostgreSQL development community. Note: This is a revised version of my talk at the Database Society of Japan in 2022.

Reading well-structured source code is an effective way to learn programming skills. The free, libre, and open source software (FLOSS) is considered an excellent tutor or learning guide for programming learning courses. However, in actual programming classes, it is not apparent that the teachers consult the source code of real applications as good examples. This talk provides several teachers' thoughts from the university who teach informatics, including programming skills.
