My profile in Japanese is profile-in-Japanese page.

Name

Ryo HAYASAKA

Gender

Male

Specialities

Software engineering. Especially, software accountability of law enforcing information systems in Legal engineering, abstract modeling, software architectures/design/structuring, software development methodologies, analysis of execution histories/logs of software systems/its applications, ease-of-evolution of software systems, tools (version control systems, configuration management systems, etc.)/development environments, patterns/frameworks, extensibility/customization of software systems, and object-oriented techniques.

My Ph.D. research theme is "Definition and Realization of Software Accountability in Legal Engineering." My master's thesis was titled, "A Software Development Project-Adapted Architecture of the Extensible Version Control System" (URI).

Research Interests

Software system properties (software accountability, self-* properties (self-adaptability, self-management, self-organization, etc.), context-awareness, context-sensitivity, etc.), aspect-orientation/feature interaction, software reuse, intentions in software development/its applications, embedded/real-time software, software analysis/program comprehension, software validation, testing/simulation, and FLOSS (Free/Libre/Open Source Software).

Activity

Use, develop, and support FLOSS, and join its development communities. If I had spare time, I could begin my FLOSS projects....

I'm a member of the administration group of ftp.jaist.ac.jp, which is one of the largest mirror servers in Japan. I'm mainly in charge of *BSD and pkgsrc mirrors.
